CIRIA (Construction Industry Research and Information Association)
The reference for what happens when an excavation goes below the water table, which is the hidden cost driver in basement digs and deep foundations on wet ground. CIRIA C750, Groundwater control: design and practice, second edition, published April 2016, 205 pages, ISBN 978-0-86017-755-5, authors Preene, Roberts and Powrie. Paywalled at GBP 110 excluding VAT (GBP 55 for members) with a minimum order of five copies, so only the catalogue page and a PDF excerpt are public. The page states the core proposition plainly: whenever an excavation is made below the water table there is a risk that it will become unstable or flood unless measures are taken to control groundwater in the surrounding soil. Scope covers the potential effect of groundwater on construction works, groundwater control and dewatering techniques as temporary works, safety management and contractual matters, legal and environmental issues, site investigation requirements, and design methods for groundwater control schemes.

CIRIA (Construction Industry Research and Information Association)
The UK code of practice for making an existing home resistant to and recoverable from flooding, and free to download after sign-in, which makes it unusually accessible for a CIRIA title. The C790 project produced four outputs a note can name separately: C790A, the Code of practice for property flood resilience, Edition 2, which sets six standards specifying what should be achieved; C790B, Guidance on the code of practice, explaining how each of the six standards should be met across the stages of a property flood resilience delivery process; C790C, Making your property more flood resilient, written for households and businesses; and C790D, Guidance for local authority planners. The code draws the distinction a renovation note should use: resistance measures reduce the amount of water entering a building, and recoverability measures limit the damage caused once water is inside, with the aim of reducing damage and speeding up recovery and reoccupation.

Considerate Constructors Scheme
A route most UK renovation articles never mention: what a neighbour affected by building work can actually do. The Scheme records all concerns, comments, compliments or complaints about a registered activity regardless of source. Once a concern is reviewed and found to relate to the Code of Considerate Practice, the Scheme informs the activity designated contact, usually the site manager or company contact, and may highlight the relevant parts of the Code. If the person raising it gives permission, their name and contact details are shared so the contact can work with them directly, particularly where compensation may be involved or where they have already been in contact with the site; if permission is not given, the Public Support team liaises on their behalf and the matter is handled confidentially. Crucially, if the construction activity is NOT registered with the Scheme, the Scheme will still contact the relevant organisation and attempt to mediate between the parties, but cannot progress the concern if that organisation does not respond. Contact is by freephone 0333 049 4600 in the UK, 1800 939 109 in the Republic of Ireland, or publicsupport@considerateconstructors.com.

Considerate Constructors Scheme
The code a registered contractor commits to, and the standard a homeowner or neighbour can measure a builder against. Registering an organisation, contractor or supplier with the Scheme is a commitment to observe and implement the Code, and the Code applies equally to all registered activities regardless of size, type or location. It has three sections. Respect the community: courteous and respectful language and appropriate behaviour in and around the activity; providing a safer environment, preventing unnecessary disturbance and reducing nuisance for the community; and proactively maintaining effective community engagement. Care for the environment: prioritising environmental issues to protect the natural environment and minimise negative impacts; optimising the use of resources including minimising carbon throughout the value chain; and engaging with the community to improve the local environment. Value the workforce: creating a supportive, inclusive and healthy workplace. Registration also means agreeing to be visited and scored by a Scheme Monitor, with conformance recognised through Certificates of Performance, Records of Performance and the Leading Lights Awards, and optional paid advisory visits available.

Passivhaus Trust
The UK body page for the Passivhaus standard, and the right citation for a note explaining low-energy standards above Building Regulations. It confirms EnerPHit is the separate, slightly relaxed Passive House Institute standard for RETROFIT projects, used where existing architecture and conservation constraints make full Passivhaus infeasible, which is the distinction most renovation articles blur. The Trust defines eight Passivhaus principles: the five building principles of insulation, airtightness, ventilation, minimised thermal bridging and high-performance windows, plus three principles of approach, namely detailed performance and comfort criteria, accurate design modelling using the Passive House Planning Package (PHPP), and rigorous quality assurance. It states the UK performance gap between designed and in-use energy conservatively results in a 60% increase in space heating demand in residential buildings, and often considerably more in non-residential, whereas Passivhaus buildings on average perform as designed. On claims: a building may reasonably be called a self-declared Passivhaus provided it satisfies all requirements of the standard, but certification must be by a registered Passivhaus Certifier independent of the design team. Caution when citing numbers: the headline criteria table on this page is published as an image and linked PDF rather than as text, so the numeric targets must be taken from the Passive House Institute criteria document itself.

Property Care Association
The Property Care Association's homeowner hub and searchable directory of PCA member specialists. Lists the service categories the PCA covers and vets against: damp control, invasive weed control, residential ventilation, structural repair, structural waterproofing, timber preservation, ground gas protection, flood protection and recovery, sump and pump maintenance, and sprayed foam evaluation. Specialists can be searched by type as a surveying and contracting company, an independent or freelance surveyor, a spray foam assessor or a ground gas verifier. The PCA describes itself as the trade body for the industry, whose members have the skills to diagnose, report on and repair buildings affected by various sources of dampness, and offers homeowner guidance pages on damp control, timber rot and woodworm, structural repairs and structural waterproofing. Use this to establish which body accredits damp and timber specialists rather than relying on a contractor's own claims.

Society for the Protection of Ancient Buildings (SPAB)
SPAB's summary of its research programme on the thermal performance of traditional buildings, undertaken to complement work by Historic Scotland on sandstone construction and English Heritage on brick, and covering vernacular walling types such as wattle and daub panelling, cob, limestone, slate and granite. The key finding: results from the first stage suggest that standard U-value calculations used across the construction industry underestimate the thermal performance of traditional walls, and that in some instances heat loss through vernacular materials can be up to three times lower than expected. The report, written by Dr Caroline Rye, compared measured in-situ U-values of various traditional vernacular walls with theoretical U-values calculated using BuildDesk U 3.4 software. SPAB warns that calculated theoretical U-values suggesting poorer performance may lead owners and professionals to adopt disproportionate energy saving interventions that are unnecessary, invasive and potentially harmful to historic fabric. Cite this before repeating a standard solid wall U-value figure for a period house.

Financial Ombudsman Service
The ombudsman's own account of what it sees and how it decides, last updated 24 July 2023, which is a stronger citation than an insurer's marketing page. Confirms that buildings insurance typically responds to accidental damage, weather such as storms, flooding, ground movement such as subsidence, and underground pipes made from pitch fibre. Lists the recurring complaint types: repairs done but the problem not fixed; the insurer insisting on repair where the consumer wants replacement; the insurer deciding the sum insured on buildings or contents is not enough to cover the claim, which it names as underinsurance; the insurer saying the customer carelessly or deliberately failed to give the true rebuild cost of the home or replacement cost of contents and cancelling the policy on that basis; a replacement offered that is not the same as what was lost; and a cash settlement too small to have the repairs done. Links its separate approaches to accidental damage, building warranties, damage to underground pipes, flood damage, gradual damage, home emergency insurance and multiple-occupancy buildings insurance.

Financial Ombudsman Service
Sets out what happens when an insurer says a homeowner gave wrong information, which is the mechanism behind most declined renovation-related claims, last updated 10 July 2026. Defines misrepresentation as information given carelessly, deliberately or recklessly that was incomplete or misleading, and non-disclosure as leaving out relevant information that was asked about. Lists the insurer's possible remedies: charge more for the policy, retrospectively apply a restriction so an ongoing or future claim is declined, settle a claim proportionately, or avoid the policy so the claim is declined outright. States the legal test the ombudsman applies is the insurer's obligations under the Consumer Insurance (Disclosure and Representations) Act 2012, asking whether the questions were clear and specific, whether the consumer took reasonable care to answer correctly, whether the answer was incorrect or incomplete, and whether the insurer would have acted differently with the correct information. Confirms the complaint route: complain to the firm first, and if it does not send a final response letter within eight weeks, or the response is unsatisfactory, bring the complaint to the ombudsman, whose service is free.

Financial Ombudsman Service
Explains the average clause, the mechanism that reduces a payout when a home is insured for less than its rebuild cost, last updated 10 July 2026. States that where a policy contains an average clause the insurer may use it so that the policyholder bears a proportion of any loss or damage if the item was insured for less than its replacement value, and that the insurer applies its own formula. Identifies the two grounds on which the ombudsman upholds such complaints: the insurer tried to apply an average clause that is not actually in the policy, and the insurer applied the average clause without ever having asked the consumer to estimate the full value of the buildings or contents. Also covers complaints where the insurer failed to ask the right question, giving the example of an application asking how much cover do you need when what the insurer wanted was the total value of everything in the home, and where the insurer did not make clear that pre-filled parts of an online form had to be checked for accuracy. Confirms the complaint route requires a formal complaint to the firm first, with the ombudsman available if no final response arrives within eight weeks.

NHS
The clinical authority for what carbon monoxide does and how many alarms a home needs. Lists symptoms as headache, dizziness, nausea or vomiting, weakness, tiredness and confusion, chest and muscle pain, shortness of breath, flushing and loss of vision, and notes the tell-tale pattern that symptoms worsen in an affected room and improve on leaving the building. Names the appliances that can produce carbon monoxide when badly installed, faulty or poorly maintained: gas boilers, gas cookers and clay ovens, gas or paraffin heaters, wood, gas and coal fires and portable generators, plus barbecues or camping stoves used indoors and engines run in a garage. The prevention advice is specific: get a carbon monoxide alarm for each room of the home containing an appliance that burns gas, oil, coal or wood, have appliances properly installed and serviced regularly by a qualified and registered engineer, and keep chimneys and flues clear. Directs readers to call NHS 111 for suspected poisoning and 999 for breathing difficulty, sudden confusion or loss of consciousness.
