Monthly official commentary on construction material prices and deliveries, the tier 1 series to cite for any materials-inflation claim. The material price index for 'All Work' increased by 6.0% in June 2026 compared with June 2025, and repair and maintenance rose 5.7% over the same period. Fabricated structural steel was the largest single price mover at 17.7% year on year. Deliveries of bricks fell 16.3% and blocks 12.3% in June 2026 against June 2025. Prices of inputs of metals and non-metallic mineral products rose 8.4% in the year to July 2026, against a revised 9.0% in the year to June, driven partly by basic iron, steel and ferro-alloys. Sawn wood over 6 mm thick was a GBP1,176 million import category in 2025 but no timber-specific annual price change is given in this edition. Published monthly, roughly one month after the reference period, with data tables in Excel and ODS.

HSE page (updated 7 October 2025) defining a domestic client under CDM 2015 as any individual having construction work done on their own home or a family member's home that is not part of a business. On a single-contractor project the contractor automatically takes on the client's legal duties; where there is more than one contractor the principal contractor takes them on, unless the client makes a written agreement for the designer to act as principal designer.

HSE's scaffolding page states that employers and self-employed contractors must assess the risk from work at height and plan the work so it is done safely, providing general access scaffolds wherever practicable. Scaffolding must be designed, erected, altered and dismantled only by competent people under the direction of a competent supervisor, following NASC Safety Guidance SG4 'Preventing falls in scaffolding operations' or equivalent manufacturer guidance for system scaffold. Strength and stability calculations are required unless the scaffold matches a generally recognised standard configuration for which a note of calculations exists, and a competent person must draw up an assembly, use and dismantling plan. Covers guard rails, toe boards, scaffold design, structures needing bespoke design, operative competence and scaffold inspection.

The section that kills the persistent claim that work to a listed building is VAT free. With effect from 1 October 2012 the zero rate for the first grant of a major interest in a substantially reconstructed protected building was withdrawn in cases where zero rating relied on three-fifths of the work, measured by cost, being approved alterations. The transitional relief that softened the change expired on 30 September 2015, and was only ever available where a relevant consent was applied for or a written contract entered into before 21 March 2012, or where 10 per cent of the substantial reconstruction was complete before that date. Zero rating survives only where the first grant of a major interest relates to a protected building substantially reconstructed from a shell. Defines a major interest as the freehold, in Scotland the absolute interest, or a lease of over 21 years, though not less than 20 years in Scotland. Ordinary alteration work to an occupied listed home is therefore standard rated at 20 per cent.

The 5 per cent conversion rate and, importantly, what it does not cover. A qualifying conversion into single household dwellings arises where the premises after conversion contain a greater or lower number, but not fewer than one, of single household dwellings, and includes a property never lived in such as an office block or a barn, a bedsit block, non-self-contained living accommodation such as staff rooms above a pub, and a dwelling previously adapted in its entirety to another use such as offices or a dental practice. It expressly does not include the creation of living accommodation that is not a single household dwelling, naming most granny annexes and additional bedrooms at a care home, nor the renovation of living accommodation used for other purposes without adaptation, such as a flat above a shop used for storage, which is directed instead to the section 8 empty homes rate. Paragraph 7.3.1 makes clear that work unrelated to changing the number of dwellings cannot be reduced rated, and works three examples through a block of sixteen flats showing that parts of a building are examined independently. Goods that are not building materials, such as carpets or fitted bedroom furniture, remain standard rated along with their installation.

The section that carries the 5 per cent empty home rate, which most renovation budgets miss. A contractor may charge VAT at 5 per cent instead of 20 per cent on renovating or altering an eligible dwelling that has not been lived in during the 2 years immediately before the work starts. Paragraph 8.3.2 sets out what proves the two years: Electoral Roll and Council Tax records, utilities companies, or an Empty Property Officer at the local authority, and states that a letter from an Empty Property Officer certifying two years empty is sufficient on its own with no other evidence needed. Paragraph 8.3.3 lists occupation that can be ignored: illegal occupation by squatters, occupation by guardians installed to deter squatters and vandals, and non-residential use such as business storage, but expressly not occasional use as a second home, which defeats the relief. Paragraph 8.3.4 allows the reduced rate to continue on all the work even where people move in while the work is carried out, provided the two-year test was met when work started. Goods that are not building materials, such as carpets or fitted bedroom furniture, must still be standard rated including the installation charge.

HMRC's internal manual chapter on the approved alteration zero rate, whose very title fixes the date the relief ended: the rules it explains are those prior to 1 October 2012, so a note that still tells readers to claim zero-rated VAT on approved alterations to a listed home is out of date by more than a decade. Manual published 19 March 2016 and updated 4 August 2026. The chapter contents show what the old test required and remains useful for pre-2012 work and for understanding the terms still used: VCONST08100 the basic conditions for zero-rating, VCONST08200 whether the work is to a protected building, VCONST08300 whether the work is an approved alteration, VCONST08350 whether the work is approved, VCONST08450 the distinction between alterations and repair or maintenance, VCONST08550 incidental alterations, VCONST08600 structures in the curtilage of a building, VCONST08700 certificates, VCONST08750 services excluded from zero-rating and VCONST08800 apportionment.

Carries the actual deduction rates, which explain the difference between two builders' quotes and the numbers on a subcontractor's payment statement. A contractor must deduct 20 per cent from payments to a registered subcontractor, called net payment status or payment under deduction, and pass it to HMRC as an advance payment towards the subcontractor's tax and National Insurance. If the subcontractor is not registered for the scheme, the contractor must deduct 30 per cent instead. A subcontractor who does not want deductions taken in advance can apply for gross payment status, which also registers them for CIS. Registration applies to a sole trader, the owner of a limited company, or a partner in a partnership or trust, and is not required of an employee.

The second volume of Approved Document B, needed when a homeowner project crosses out of purely domestic use. Paragraph 0.1 draws the line: Volume 1 deals solely with dwellings INCLUDING blocks of flats, so a flat conversion stays in Volume 1, while Volume 2 covers every other building type. Table 0.1 sets the purpose groups: 1(a) flat, 1(b) dwellinghouse with a habitable storey at least 4.5m above ground up to 18m, 1(c) dwellinghouse with no habitable storey 4.5m above ground, then 2(a) residential institutional, 2(b) residential other (hotel, boarding house, hall of residence, hostel), 3 office, 4 shop and commercial, 5 assembly and recreation, 6 industrial, 7(a) storage and 7(b) car parks for vehicles up to 2,500kg gross. Its notes keep work within purpose group 1: surgeries, consulting rooms or offices forming part of a dwellinghouse and used by an occupant in a professional capacity stay in group 1 provided they total no more than 50m2, and a detached garage or open carport of no more than 40m2 stays in group 1(c). Paragraph 0.21 requires a separate purpose group for an ancillary use if that use is a flat, or if the building or compartment exceeds 280m2 and the ancillary use is more than one fifth of the total floor area; paragraph 0.22 requires separate purpose groups for genuinely independent uses such as shops with offices above, and the more onerous guidance applies where there is doubt. Paragraphs 0.23 and 0.24 require Volume 1 to be consulted as well for mixed use buildings that include dwellings, and paragraph 3.2 requires separate escape routes, or other effective protection of common escape routes, where a building has storeys or parts of storeys in different purpose groups.

The current NPPF, published 17 August 2026 (130 pages), replacing the framework first published March 2012 and revised July 2018, February 2019, July 2021, September 2023, December 2023 and December 2024, and also replacing Planning policy for traveller sites. The single most important thing about this edition for anyone citing it: the framework has been completely restructured from continuously numbered paragraphs into lettered and numbered policies, so every existing citation of an NPPF paragraph number is now stale. The chapters are Plan-making (PM1 to 17), Decision-making (DM1 to 10), Achieving sustainable development (S1 to 6), Climate change (CC1 to 3), Homes (HO1 to 13), Economy (E1 to 4), Town centres (TC1 to 4), Communications (CO1 to 2), Clean energy and water (W1 to 4), Minerals (M1 to 6), Making effective use of land (L1 to 3), Green Belt (GB1 to 8), Well-designed places (DP1 to 4), Transport (TR1 to 8), Healthy communities (HC1 to 8), Pollution (P1 to 6), Flood risk (F1 to 9), Natural environment (N1 to 6) and Historic environment (HE1 to 10). Policy GB7(1)(b) is the one homeowners meet: the reuse, extension, alteration or replacement of an existing building is not inappropriate development in the Green Belt provided the existing building is of permanent and substantial construction, is lawful in planning terms, and any extension or alteration will not result in a disproportionate increase in size compared to the original building, with footnote 40 defining the original building as the building that existed on 1 July 1948 or, if later, as it was originally built. Policy HE5(2)(c) now defines substantial harm expressly, as where a development proposal would seriously affect a key element of a heritage asset significance, and HE4(2) requires clear and convincing justification for any harm to a designated heritage asset.

MHCLG's official explanatory booklet on the Party Wall etc. Act 1996, applying to England and Wales, Crown copyright 2016. Explains the Act's effect on the Building Owner who wishes to carry out work covered by the Act and the Adjoining Owner who receives notice of it. Defines 'owner' for the Act's purposes as including anyone holding the freehold title, holding a leasehold title for a period exceeding one year, under contract to purchase such a title, or entitled to receive rents from the property, so a single property can have more than one owner. States clearly that the Act is separate from planning and building regulations control: agreement under the Act does not remove the need for planning permission or building regulations compliance, and neither does planning permission or building regulations compliance remove the need to comply with the Act. Carries a disclaimer that the booklet is a general guide and not an authoritative interpretation of the law.

SCOTLAND, with no England equivalent: a seller in Scotland must commission a Home Report before marketing, where an England seller commissions nothing and the buyer pays for their own survey. Introduced in 2008 to give buyers and sellers better information on property condition before offers are placed, to stop duplicate surveys and valuations, and to stop artificially low asking prices. The Home Report comprises three documents: an Energy Report, a Property Questionnaire and a Single Survey, and only surveyors registered with or authorised to practise by RICS may produce the Single Survey. It was developed with the Home Report Implementation Group, whose members included RICS, the Law Society of Scotland, the Council of Mortgage Lenders, the National Association of Estate Agents and Citizens Advice Scotland.

Section 20(1) prohibits practising or carrying on business under any name, style or title containing the word 'architect' unless the person is registered with ARB. Section 20(2) preserves the designations 'naval architect', 'landscape architect' and 'golf-course architect'. Section 20(3) lets a company, firm or partnership trade under a name containing 'architect' only where the architecture side of the business is under the control and management of a registered person who does not act in that capacity for another business at the same time, and where the work is carried on by or under the supervision of a registered person at every premises. Section 20(6) makes clear that being employed by another person does not stop someone from practising, section 20(7) defines business to include any undertaking carried on for gain or where services are not provided free, and section 20(8) preserves the validity of building contracts in customary form. This is why an architectural technologist or designer may lawfully do the same drawings but not use the protected title.

Section 36(1) lets the building control authority, without prejudice to prosecuting for a fine, serve notice on the owner requiring work that contravenes building regulations to be pulled down or removed, or at the owner's election altered so as to comply. Section 36(2) applies the same power where work was executed without an application for building control approval, despite refusal of one, or otherwise than in accordance with the requirements of a granted application. Section 36(3) gives the owner 28 days, or longer if the appropriate court or tribunal allows, before the authority may carry out the work itself and recover the reasonable expenses. Section 36(4) is the key protection: a section 36 notice may not be given after 10 years from the date the work was completed. Sections 36(5) and 36(5A) bar a section 36 notice where a building control approval application for work that is not higher-risk building work was granted and the work was executed in accordance with the approved plans and any requirement imposed.

Section 34(2) exempts an occupier of domestic property in respect of household waste produced on the property, but section 34(2A) still requires that occupier in England or Wales to take reasonable measures to ensure any transfer of that household waste is only to an authorised person. Section 34(3) lists authorised persons, including waste collection authorities, waste management licence holders and carriers registered under the Control of Pollution (Amendment) Act 1989.

The source for why a skip on the road needs a council permit while a skip on your own driveway does not. Section 139 makes it unlawful to deposit a builder's skip on a highway without the permission of the highway authority, and that permission names the highway and may attach conditions on the siting of the skip, its dimensions, the painting of the skip for visibility, the care and disposal of its contents, its lighting and guarding, and its removal at the end of the period. The owner must keep the skip properly lighted during the hours of darkness, clearly and indelibly marked with the owner's name and telephone number or address, and remove it as soon as practicable after it has been filled. Breach carries a fine not exceeding level 3 on the standard scale, with a defence where the breach was due to the act or default of another person and the owner took all reasonable precautions and exercised all due diligence. A builder's skip is defined as a container designed to be carried on a road vehicle for storing materials or disposing of rubble and waste.

The RICS professional statement that defines the three survey levels a homebuyer is offered, and the standard a note should cite instead of describing surveys loosely. Page updated 17 June 2026. The 1st edition was published in 2019 and became effective in 2021; it sets mandatory requirements for RICS members and regulated firms in the UK delivering residential property surveys, and it replaced and harmonised the earlier RICS residential survey publications. It defines four report products, RICS Home Survey Level 1, Level 2 (survey only), Level 2 (survey and valuation) and Level 3, and a member needs a Home Surveys Licence to produce any of them. The old report formats were permitted only during a transition period from 1 March to 31 August 2021, and the new reports have been mandatory since 1 September 2021. The standard is currently under review: a public consultation on a 2nd edition ran from 19 August to 14 October 2025, informed by a survey of 325 members and a UK consumer survey of over 1,400 homeowners, with proposed changes covering AI and drone or camera-pole technology, greater clarity on survey levels, optional valuation at all levels, guidance for additional risk dwellings, and retrofit assessments. RICS states members should continue to use the 1st edition until the 2nd edition takes full effect, so any note dating the change should say the 2nd edition is not yet in force.

NRM 1 is issued by the RICS Quantity Surveying and Construction Professional Group as one of a suite of three (NRM 1 order of cost estimating and cost planning, NRM 2 detailed measurement for building works, NRM 3 order of cost estimating and elemental cost planning for building maintenance works), all reissued in October 2022 as practice information having been published in October 2021 as guidance notes, with no material change to content. NRM 1 covers quantification of building works for cost estimates and cost plans, and also how to quantify the items that are not measurable building work: preliminaries, overheads and profit, project team and design team fees, risk allowances, inflation, and other development and project costs. It sets out the floor area method for order of cost estimates and defines the terms a note should use precisely: cost per m2 of gross internal floor area (cost/m2 of GIFA) is the unit rate which, when multiplied by the gross internal floor area, gives the total building works estimate, and gross internal floor area (GIFA, also gross internal area or GIA) is defined in Appendix A with reference to the latest edition of the RICS Code of Measuring Practice. It also distinguishes GEA (gross external area) and NIA (net internal area). This is the source to cite for why a cost per m2 figure is meaningless without stating which area basis it uses.

Building Control Northern Ireland (the 11 district councils)
NORTHERN IRELAND. The scale of building control fees is set centrally by the Department of Finance under the Building (Prescribed Fees) Regulations (Northern Ireland) 1997 as amended in 2013 and 2022, with the current fees applying to applications made after 1 April 2022. Unlike England, where each authority or private approver sets its own charges, NI fees are prescribed and are not subject to annual increase, being revised periodically by the Department. There is a FIXED RATE plan fee for certain domestic extensions, detached domestic buildings such as garages, roofspace conversions and houses up to 250 square metres. For small extensions UNDER 20 SQUARE METRES the plan fee also covers all subsequent site inspections, so there is no separate inspection charge. Other work is charged on an estimated cost of works basis using a contractor's cost. Where part of the works is solely for a person with a disability that part is excluded from the fee calculation, and a full exemption applies where the works are exclusively for a person with a disability or are described as exempt. A fee calculator is provided.

Dwr Cymru Welsh Water
WALES and parts of England, since Dwr Cymru Welsh Water's operating area crosses the border. You must notify Welsh Water if extending over or within THREE METRES of a public sewer or lateral drain, across a network of more than 30,000 km of sewers. An application is unlikely to be accepted where the sewer's internal diameter exceeds 225 mm or the pipe is deeper than 3 metres, and a greater standoff may then be required; commercial extensions and new detached structures need a sewer diversion instead. Nothing may be built over or near water mains or pressurised sewers. There are two routes, self-certification against set criteria and a full application with technical assessment. The published charges are £278.10 for consent by letter with no network alterations, £936.85 for consent by letter after alterations, and £1,053.00 for consent by legal agreement, covering administration, any site inspection, technical support, liaison with building control or the approved inspector, and issue of the consent. Work must not start until consent is given, and sewer traces are strongly recommended before excavating. Accessibility adaptations get extra support via the Build Over Sewers team on 0800 917 2652.

Its structure is progressive in the same way as SDLT: the percentage rate for each band applies only to the part of the price above the relevant threshold and up to the next, and nothing is payable below the first threshold. Separate rate and band tables exist for residential properties, residential property with the Additional Dwelling Supplement, non-residential properties and commercial leases. The Additional Dwelling Supplement is the Scottish equivalent of the higher rates for additional properties. Revenue Scotland also administers the Scottish Landfill Tax, the Scottish Aggregates Tax and the Scottish Building Safety Levy, and publishes a tax calculator and legislation guidance.

HSE's definition of a contractor under CDM 2015: anyone who directly employs or engages construction workers or manages construction work, including sub-contractors and any self-employed worker or business that carries out, manages or controls construction work, who must have the skills, knowledge, experience and, where relevant, the organisational capability to do the work safely. On all projects a contractor must make sure the client is aware of the CDM 2015 client duties before work starts, plan manage and monitor all their own work taking account of risks to anyone affected including members of the public, check that workers they employ or appoint have the necessary skills knowledge training and experience or are obtaining them, provide a suitable site-specific induction unless the principal contractor has already done so, provide appropriate supervision information and instructions, take reasonable steps to prevent unauthorised access before starting on site, and provide and maintain suitable welfare facilities from the start. On projects with more than one contractor they must also coordinate with the rest of the project team, comply with directions from the principal designer or principal contractor, and comply with the relevant parts of the construction phase plan. This is the source for what changes when a homeowner engages several trades directly rather than one main contractor.

The HSE's proportionality statement on legionella in domestic property, which corrects the common claim that landlords need a paid legionella certificate. Defines a landlord for this purpose as anyone renting out a property they own under a lease or licence shorter than 7 years, covering local authorities, housing associations, private landlords, housing co-operatives and hostels, and including renting a room within your own home. Identifies the legal basis as section 3(2) of the Health and Safety at Work etc Act 1974, with section 53 treating landlords as self-employed, plus the Control of Substances Hazardous to Health Regulations, and the Approved Code of Practice L8 on the control of legionella bacteria in water systems. States plainly that while there is a duty to assess the risk, this does not require an in-depth, detailed assessment, and that risks in most residential settings are generally low because of regular water usage and turnover. Sets out the low-risk profile: daily water use sufficient to turn over the entire system, cold water direct from a wholesome mains supply with no stored water tanks, and hot water from instantaneous or low volume heaters.

The HSE leaflet that carries the temperature range every hot water and cylinder note should cite. States there is a reasonably foreseeable legionella risk where water is stored or re-circulated, where water temperature in all or part of the system is between 20 and 45 degrees Celsius, where there are nutrients such as rust, sludge, scale and organic matter, and where water droplets can be produced and dispersed, giving showers and cooling tower aerosols as examples. Defines legionellosis as the collective name for the pneumonia-like illness caused by legionella bacteria, covering legionnaires' disease itself plus the less serious Pontiac fever and Lochgoilhead fever, and notes everyone is susceptible but higher risk attaches to people over 45, smokers and heavy drinkers, people with chronic respiratory or kidney disease, and anyone with an impaired immune system. Legionella pneumophila occurs naturally in rivers, lakes and reservoirs in low numbers but multiplies in purpose-built systems including cooling towers, evaporative condensers, hot and cold water systems, whirlpool and spa pools, humidifiers and air washers. Published 04/12 as leaflet INDG458, and points to the Approved Code of Practice L8 for detail on control.

HSE's dutyholder table for CDM 2015. Defines a domestic client as someone having construction work done on their own home, or a family member's home, that is not part of a business; domestic clients are in scope but their client duties normally transfer to the contractor on a single contractor project and to the principal contractor where there is more than one contractor, unless the domestic client instead makes a written agreement with the principal designer to carry out the client duties. Commercial clients must make suitable arrangements for managing the project, appoint other dutyholders, allocate sufficient time and resources, prepare and provide relevant information, ensure the principal designer and principal contractor carry out their duties, and ensure welfare facilities are provided. Designers must eliminate, reduce or control foreseeable risks arising during construction and during maintenance and use. Principal designers are designers appointed by the client on projects involving more than one contractor.

HM Land Registry's collection of UK House Price Index reports for England, Scotland, Wales and Northern Ireland, published as reports and CSV, last updated 19 August 2026. The UK HPI is a National Statistic; the Northern Ireland House Price Index is calculated and published quarterly, and the Northern Ireland monthly sales volume is now estimated by dividing the quarterly total by 3. The July 2026 UK HPI was due at 9.30am on Wednesday 16 September 2026. Notes the March 2024 revision of estimates from January 2021 onward and a later identified error in cash and mortgage transaction counts for January 2021 to December 2022 which did not affect the indices or price levels. This is the authoritative average-price-by-local-authority source for any value uplift or 'extend or move' calculation.

The SDLT band table for a single residential property: zero up to 125,000 pounds, 2% on the portion from 125,001 to 250,000 pounds, 5% from 250,001 to 925,000 pounds, 10% from 925,001 to 1.5 million pounds and 12% above 1.5 million pounds. A 5% surcharge is usually added on top of these rates if the buyer already owns another residential property. HMRC's worked example gives 4,750 pounds on a 295,000 pound purchase (0 plus 2,500 plus 2,250). New residential leaseholds pay SDLT on the lease premium at these rates, plus 1% on the portion of the net present value of rent above the 125,000 pound threshold; this does not apply to assigned leases. This is the moving cost that has to be set against an extension or loft conversion budget.

Defines the boundary of the scheme, which decides whether a given trade's invoice should carry a CIS deduction. Work covered is most construction work to a permanent or temporary building or structure and civil engineering such as roads and bridges, and expressly includes preparing the site such as laying foundations and access works, demolition and dismantling, building work, alterations, repairs and decorating, installing systems for heating, lighting, power, water and ventilation, and cleaning the inside of buildings after construction work. The listed exceptions are architecture and surveying, scaffolding hire with no labour, carpet fitting, making materials used in construction including plant and machinery, delivering materials, and work on construction sites that is clearly not construction such as running a canteen. Confirms contractors must register but subcontractors need not, though unregistered subcontractors suffer deductions at a higher rate, and that the same rules apply to a business based outside the UK doing construction work in the UK.

The single most useful correction for any derelict-property or doer-upper note. HMRC states flatly that there is no tax relief and no lower rate of SDLT for uninhabitable properties, that a very high proportion of repayment claims in this area are wrong, and that buyers should be cautious about being misled by repayment agents. Being suitable for use as a dwelling is not the same as being ready for immediate occupation, and if a building retains the character or identity of a residential property it is wholly residential for SDLT despite disrepair. Lists the defects that expressly do not make a property unsuitable for use as a dwelling, even in combination: temporary removal of bathroom or kitchen facilities before sale, substantial repair or replacement of windows, floors, doors or roof, replacement boiler and pipework, unsafe electrical wiring, services switched off, pest infestation, damp proofing needed or plasterboard damage, flood damage, the presence of asbestos, and structural defects that can be repaired. Past use as a dwelling is a strong indicator of suitability. Cites the Court of Appeal in Amarjeet and Tajinder Mudan [2025] EWCA Civ 799 as now legally binding, upholding the Upper Tribunal at [2024] UKUT 307 (TCC).

The five conditions that must all be met for a sale to be free of Capital Gains Tax under Private Residence Relief, two of which renovation choices can break. You must have one home and have lived in it as your main home for the whole period of ownership; you must not have let part of it out, though having a lodger does not count; you must not have used part of the home exclusively for business purposes, and using a room as a temporary or occasional office expressly does not count as exclusive business use; the grounds including all buildings must be less than 5,000 square metres, just over an acre; and you must not have bought it just to make a gain. Where all apply the relief is automatic and no tax is due; where any fails there may be tax to pay. Married couples and civil partners can only count one property as their main home at any one time. The exclusive-business-use point is what a dedicated garden office or converted consulting room can trigger.

The duties that attach to anyone who pays subcontractors for construction work, which matters for a homeowner acting as their own main contractor and for judging whether a builder is operating properly. Registration as a contractor is required if you pay subcontractors to do construction work, or if your business does not do construction work but has spent more than 3 million pounds on construction in the 12 months since the first payment. The six rules are: register before taking on the first subcontractor; check whether the person should be employed rather than subcontracted, with a penalty if they should be an employee; verify with HMRC that subcontractors are registered with CIS; make deductions from payments and pay them to HMRC, the deductions counting as advance payments towards the subcontractor's tax and National Insurance; file monthly returns and keep full CIS records, with a penalty for failing to; and notify HMRC of changes to the business.
