Northern Ireland's accessibility rules for a dwelling's sanitary provision, October 2012. Section 10 requires a water closet in the entrance storey, or the principal storey, reachable from the habitable rooms of that storey without negotiating a stair; where a bathroom exists on that storey the WC may sit inside it. Paragraph 10.2 requires a clear space of not less than 900 mm by 750 mm at the WC for a person with a disability, and allows the washbasin to project into that space provided it does not impede access; frontal access centres the space on the pan, oblique access offsets it towards the approach. Paragraph 10.4 requires the doorway to be positioned so a wheelchair user can reach the clear space and, for oblique access, that the door edge is not in front of or 250 mm behind the WC unless there is room to manoeuvre. Paragraph 10.5 requires the door to open outwards or not to impinge on the clear space at any point of its swing. Table 10.1 sets clear opening widths against circulation route width: 750 mm head on from a 900 mm route, 750 mm not head on from 1200 mm, 775 mm not head on from 1050 mm, 800 mm not head on from 900 mm. Section 11 covers socket outlet and switch heights.

Northern Ireland's equivalent of Approved Document G, issued under the Building Regulations (Northern Ireland) 2012 and the source to cite for a reader in NI. Regulation 85(1) requires a dwelling to have at least one water closet, one washbasin and one fixed bath or shower. Regulation 86(2) requires every washbasin, bath and shower to have a piped supply of hot and cold water. Regulation 87(2) requires the hot water supply to any fixed bath to be designed and installed so the temperature delivered to that bath does not exceed 48 degrees C, the same scalding limit as England and Wales. Regulation 88 governs unvented hot water storage systems, and the guidance splits them at 500 litres storage and 45 kW: Section 2 covers systems up to 500 litres and 45 kW, then systems over those thresholds, with a separate part on discharge pipes from tundishes.

Northern Ireland's ventilation guidance, the devolved counterpart to Approved Document F, and a clean source for extract rates because its Table 2.1 sets them out room by room. Intermittent extract minimum rates: kitchen 30 litres per second adjacent to the hob or 60 litres per second elsewhere, utility room 30 litres per second, bathroom 15 litres per second, sanitary accommodation 6 litres per second. Continuous extract minimum high rates: kitchen 13 litres per second, utility room 8, bathroom 8, sanitary accommodation 6. The whole-dwelling ventilation rate should not be less than 0.3 litres per second per square metre of internal floor area, and where a greater level of occupancy is expected an extra 4 litres per second per occupant should be added. It describes System 1, background ventilators with intermittent extract fans, as the common domestic strategy. The 30 versus 60 litres per second split is the figure that decides whether a cooker hood can sit above the hob or must be sized up when placed away from it, for example over an island.

GOV.UK
The council grant for adapting a home, and what work it can pay for. Eligibility covers physical disability, learning disability, age-related needs, autism, cognitive impairment such as dementia, a progressive condition such as motor neurone disease, terminal illness and mental health conditions. The listed works are wide enough to cover substantial building work: widening doors and installing ramps or grab rails, improving access to rooms and facilities with a stairlift or level access shower, improving access to the garden, building an extension such as a downstairs bedroom, providing a heating system suitable for the applicant's needs, and adapting heating or lighting controls. Confirms a Disabled Facilities Grant does not affect any other benefits the applicant receives.

GOV.UK
Carries the maximum grant by nation, which differs across the UK and is the figure most articles quote wrongly. England up to 30,000 pounds, Wales up to 36,000 pounds, Northern Ireland up to 25,000 pounds, and in Scotland Disabled Facilities Grants are not available at all, with support instead provided through equipment and adaptations schemes. Some councils may give more. The award is means tested on household income and household savings over 6,000 pounds, but disabled children under 18 can get a grant without their parents' income being taken into account, and landlords can get one without their income and savings being assessed, though the council may require the property to be let to another disabled person if the tenant moves within 5 years. Warns that starting work before the council approves the application may mean no grant at all. Payment is either in instalments as work progresses or in full on completion, paid to the contractor directly or through the applicant, and where the applicant or a relative does the work the council will normally only accept invoices for materials or services bought.

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.

HSG274 Part 2, second edition 2024, ISBN 978 0 7176 6753 6, issued under the HSW Act 1974, COSHH 2002 and the Management of Health and Safety at Work Regulations 1999. Paragraph 2 sets the risk trigger: water stored or recirculated, any part of the system between 20 and 45 degrees C, deposits such as rust, sludge or scale, and droplets that can be dispersed. Paragraph 2.6 gives the temperature regime: cold below 20 degrees C, hot stored at least at 60 degrees C and distributed so it reaches 50 degrees C (55 degrees C in healthcare) within one minute at the outlets. Cold branches should deliver close to incoming temperature within two minutes of running, and stored cold water should not normally exceed one day's use. Combination cylinders may store cold at up to 25 degrees C serving other outlets or 38 degrees C serving the hot vessel only, per the Water Supply (Water Fittings) Regulations 1999, the Scottish Water Byelaws and BS 3198. Circulating return to the calorifier not less than 50 degrees C; shunt pumps must raise the whole vessel, including solar-heated cylinders, to 60 degrees C. Appendices 4 and 5 illustrate sentinel points.

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.

The HSE's own temperature rules for domestic hot and cold water, and the reason a cylinder thermostat should not simply be turned down to save money. Cold water systems should be maintained where possible at a temperature below 20 degrees C. Hot water should be stored at least at 60 degrees C and distributed so that it reaches 50 degrees C, or 55 degrees C in healthcare premises, within one minute at the outlets. Against that, there is a scalding risk where water comes out of taps above 44 degrees C. For most people the scalding risk is minimal where water is delivered up to 50 degrees C at hand-wash basins and a hot water warning notice may be sufficient, but where vulnerable people can access baths or showers and the scalding risk is significant, a Type 3 thermostatic mixing valve must be fitted to prevent water discharging above 44 degrees C. The page sets out the system types it applies to, including gravity fed hot and cold storage, hot water storage only, and cold storage only with mains pressure hot water.

The ACOP that gives legionella control its legal force. Fourth edition 2013, ISBN 9780717666157. It sets five dutyholder duties that carry Approved Code of Practice status, meaning a court may take failure to follow them as evidence of breach unless compliance was achieved another way: identify and assess sources of risk, prepare a written scheme to prevent or control the risk, implement manage and monitor the precautions, keep records of them, and appoint a named responsible person to manage legionella control. The fourth edition raised risk assessment, the role of the responsible person, the control scheme, review of control measures and the duties of the water system supply chain from guidance to ACOP status. Detailed technical parameters, including the 20 to 45 degrees C growth band and the 60 and 50 degrees C storage and outlet temperatures, sit in the companion HSG274 Parts 1 to 3 rather than in L8 itself.

The page that explains why an R rating on a tile datasheet is not the reassurance retailers imply. HSE answers the question how do I check whether my floor is slip resistant by pointing first to the manufacturer's technical data sheet, then warning that a floor labelled R9 should be treated with caution because it indicates slipperiness when wet: the R scale comes from the German shod ramp test, which uses an oil-covered ramp and a walker in boots, and the lowest classes tell you little about a wet barefoot bathroom or a contaminated kitchen floor. HSE's own definitive measurement is the pendulum test to BS 7976, available through specialist testing services. It explains surface roughness as the fine texture of the flooring, with the analogy that sandpaper would stop you slipping in the wet whereas the smooth surface of paper would be slippery, and notes that roughness readings feed HSE's Slips Assessment Tool. It also warns that safety floors, being rougher, hold more cleaning solution and leave residue as it evaporates unless a dry mop or wet vacuum is used, and that metal profiling wears round and loses grip.
