Every law, deadline and sector statistic we quote on this site comes from a published source, and they're all listed here by topic, with a short note on why each one is relevant.
Each entry below opens the original document in a new tab.
The Acts of Parliament and statutory instruments that create the duty.
Awaab's Law is Section 42 of the Social Housing (Regulation) Act 2023.
The primary statute that creates Awaab's Law. Read it for the exact wording of the new duty on social landlords and the 'all reasonable endeavours' defence.
Section 42 inserts sections 10A and 10B into the Landlord and Tenant Act 1985.
How Awaab's Law actually binds landlords. Section 42 inserts a new implied covenant into every relevant tenancy agreement, which is what residents (and their lawyers) can sue on.
Detailed timeframes sit in The Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025 (SI 2025/1042).
The statutory instrument that defines the actual deadlines: 24 hours, 10 working days, 3 working days, 5 working days. The numbers everyone quotes come from this document.
The Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025 (SI 2025/1042) came into force on 27 October 2025 and apply to lessors of social homes in England.
Confirms the date the clock started for damp and mould plus emergency hazards. The opening page of the SI carries the commencement provisions in full.
The Renters' Rights Act 2025 received Royal Assent on 27 October 2025.
The legal vehicle for extending Awaab's Law to the private rented sector. Royal Assent confirms the Act exists; commencement of individual provisions is staged.
The Renters' Rights Act 2025 extends Awaab's Law to the private rented sector; the commencement date is subject to further consultation (published in the MHCLG Implementation Roadmap, 13 November 2025).
The single best guide to when each PRS reform commences. Indicates that the Awaab's Law extension to private renters is subject to further consultation, not a fixed date yet.
Awaab's Law was announced by the UK government in February 2023.
The original government announcement. Useful for tracing the policy timeline from inquest finding (Nov 2022) to enacted regulation (Oct 2025).
From 6 October 2026, Scottish landlords must investigate reports of damp and mould within 10 working days and begin any required repairs within 5 working days of completing the investigation, under The Investigation and Commencement of Repair (Scotland) Regulations 2026.
Scotland's parallel regime, with its own dates and slightly different wording. Essential reading for any portfolio that crosses the border.
Note: The underlying draft SI is at https://www.legislation.gov.uk/sdsi/2026/9780111065594/contents.
In Wales, section 91 of the Renting Homes (Wales) Act 2016 (in force 1 December 2022) requires the landlord to ensure the dwelling is fit for human habitation on the occupation date and for the duration of the contract. It binds community landlords - housing associations and councils - through secure contracts.
The core ongoing duty for Welsh social landlords - the Welsh counterpart to England's repairing obligations. Every Welsh damp and mould case starts here.
The Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022 (in force 1 December 2022) list 29 matters for assessing fitness; matter 1 is 'Damp, mites and mould or fungal growth' - 'exposure to house dust mites, damp, mould or fungal growths'.
The Welsh fitness test puts damp and mould first on the list. If a Welsh home has a damp or mould problem, the fitness duty is engaged.
The Housing Health and Safety Rating System (England) (Amendment) Regulations 2026 (SI 2026/571) came into force on 23 June 2026. They replace the A-J hazard bands with High, Medium and Low; rename the four classes of harm to Extreme, Severe, Serious and Moderate; and reorganise the prescribed hazard descriptions.
Awaab's Law hazard definitions hang off the HHSRS, so a change to how hazards are assessed and banded lands directly in damp-and-mould triage and assessment processes.
The MHCLG implementation roadmap for the Renters' Rights Act 2025 states: "We will extend Awaab's Law to the PRS, setting clear legally enforceable timeframes within which PRS landlords must make homes safe where they contain serious hazards." The private-rented wording is "serious hazards"; the social-housing regulations use "significant hazards".
The two sectors use different statutory words. For private renting the government says "serious hazards"; the social-housing regulations say "significant hazards". They are not interchangeable.
The MHCLG implementation roadmap expects the new private rented sector Landlord Ombudsman to begin "in 2028, when the Secretary of State is confident the service is ready for delivery". Membership will be mandatory for PRS landlords, funded through a charging model.
The government's expected start date, 2028, for the new ombudsman that private landlords will have to join.
Government guidance on the deadlines: the four statutory windows in England and the WHQS timescales in Wales.
Emergency hazards: the landlord must investigate and complete relevant safety works within 24 hours of becoming aware.
The government's official guide to the 24-hour clock for emergency hazards. The plain-English companion to the regulations, written for social landlords.
Significant (damp and mould) hazards must be investigated within 10 working days of becoming aware.
Defines the deadline that applies to almost every damp-and-mould case. Read this for what the government considers an acceptable investigation.
The landlord must provide a written summary of the investigation findings to the tenant within 3 working days of the investigation concluding.
The often-overlooked third clock. Within 3 working days of concluding an investigation, the landlord must hand a written summary to the resident. Useful when drafting templates.
Relevant safety work for significant hazards must be completed within 5 working days of the investigation concluding.
The completion clock for damp-and-mould remediation. Tells operations teams what counts as 'relevant safety work' and what they must finish in the 5-working-day window.
If the landlord cannot complete safety work in the initial remediation period, they must secure suitable alternative accommodation at their expense until the work is done.
The financial backstop. If a landlord cannot complete the work in time, they must rehouse the resident at their own cost. Worth reading before any case where the deadline is at risk.
From 1 April 2026, the WHQS Addendum (Responding to Hazards, Element 1c) requires Welsh social landlords to investigate hazards with imminent risk of harm within 24 hours and remedy within a further 24 hours; otherwise investigate within 10 working days and remedy within a further 5 working days, with a written summary plan to the tenant within 5 working days where the timescale cannot be met. Covers all HHSRS hazards except overcrowding; damp and mould is the first listed. Reported quarterly through the WHQS compliance return.
Wales's answer to the same problem Awaab's Law addresses in England - but delivered as a regulatory standard with reporting duties, not an implied tenancy term. The timescales Welsh operations teams now run to.
Note: Announced by Written Statement, 19 December 2025 (gov.wales). It is a rule and statutory guidance under the WHQS, not legislation. First quarterly report due end of June 2026.
When the law expands beyond damp and mould, in 2026 and 2027.
Phase 1 covers damp and mould plus emergency hazards (from 27 October 2025). Phase 2 (2026) adds excess cold and heat, falls, structural collapse, fire, electrical hazards and explosions, and hygiene hazards. Phase 3 (2027) covers all remaining HHSRS hazards except overcrowding.
The official phasing schedule. Tells you which hazards are in scope today and which arrive in 2026 and 2027 - the planning horizon for any operations team.
How regulators and ombudsmen in England and Wales hold landlords to account.
Awaab's Law contains an 'all reasonable endeavours' defence: section 10A(5) of the Landlord and Tenant Act 1985 (inserted by Section 42 of the Social Housing (Regulation) Act 2023) makes it a defence for the lessor to prove they used all reasonable endeavours to avoid the breach.
The only statutory defence available when a deadline is missed. The exact statutory phrase is 'all reasonable endeavours' - read the section for the wording a court or the Ombudsman would start from.
The Regulator of Social Housing's Safety and Quality Standard has been in force since 1 April 2024 as one of four revised Consumer Standards.
One of the four standards the Regulator of Social Housing inspects against. Damp and mould failures are routinely judged here; this decision statement confirms the standard's scope and effect date.
The Housing Ombudsman's Complaint Handling Code became statutory on 1 April 2024.
The statutory rules for how social landlords must handle complaints, including damp and mould. Treat as the procedural baseline for every case file the Ombudsman might review.
The Regulator of Social Housing can issue unlimited fines: Schedule 3 paragraph 6 of the Social Housing (Regulation) Act 2023 amends the Housing and Regeneration Act 2008 so the penalty "is unlimited", in force 1 April 2024 (SI 2024/437).
The provision that removed the old £5,000 cap on regulatory penalties. In force since 1 April 2024 - the financial ceiling on enforcement is gone.
The Regulator of Social Housing aims to inspect registered providers with 1,000 or more social homes at least once every four years ('we aim to carry out a programmed inspection at least every four years'; frequency is risk-based).
The most-cited inspection rhythm for the regulated sector. If you are a registered provider with at least 1,000 social homes, this confirms the Regulator's inspection cadence.
On 15 December 2022 the Regulator of Social Housing issued a regulatory notice finding Rochdale Boroughwide Housing in breach of consumer and governance standards in relation to damp and mould.
An example of what an RSH breach finding for damp and mould looks like in practice. Cited often as the template for serious regulatory consequences.
Note: The notice was lifted on 26 March 2025 (issues resolved; RBH back in compliance). The breach was of the Home Standard in force at the time.
The UK government withheld £1 million of funding from Rochdale Boroughwide Housing in response to the Awaab Ishak case - announced 24 November 2022 and confirmed in the December 2022 gov.uk update.
The financial precedent. £1 million of funding pulled from a single landlord over damp and mould - illustrates the political pressure that produced the law.
The Welsh Housing Quality Standard 2023 applies to all social housing in Wales from 1 April 2024. Element 1b: 'Homes must be free from damp' - including persistent condensation; the absence of a Category 1 hazard alone does not constitute a pass.
The Welsh quality standard is stricter in wording than the English hazard test: free from damp, full stop, including persistent condensation.
Welsh housing associations are regulated by the Welsh Government (Regulatory Framework for Housing Associations Registered in Wales); tenant complaints about Welsh councils and housing associations go to the Public Services Ombudsman for Wales, not the (English) Housing Ombudsman.
Wales has a different accountability map: the Welsh Government regulates, and complaints go to the Public Services Ombudsman for Wales. When a document says 'the Ombudsman', check which one it means.
Spotlight reports, annual reviews, and notable determinations.
The Housing Ombudsman's Spotlight report 'Damp and mould: it's not lifestyle' was published in October 2021 with 26 recommendations.
The report that set the no-blame standard for the sector. The 26 recommendations are the de facto checklist regulators and Ombudsman investigators still measure landlords against.
The Housing Ombudsman published a follow-up Spotlight on damp and mould in February 2023.
An update on how landlords had responded to the 2021 report. Useful for tracking the gap between guidance and behaviour - and for benchmarking your own progress.
The Housing Ombudsman recorded over 100 severe maladministration findings on damp and mould across 20 named landlords (published 16 October 2024).
Confirms the scale and seriousness of damp-and-mould casework at the Ombudsman. Severe maladministration is the most damaging finding short of regulatory action.
Housing Ombudsman (Richard Blakeway, October 2024): 'This is a topic that now dominates half of our casework.' The Ombudsman's own report index renders this as 'dominates 50% of our casework'.
The Ombudsman's own measure of how much of its work is damp and mould. Use it when sizing the staff and contractor capacity you'll need.
Housing Ombudsman Annual Complaints Review 2024-25: 7,082 determinations (up 30% year on year); more than 40% of total compensation ordered was for leaks, damp and mould; 578 compensation orders above £2,000; the largest single order was almost £32,000; and 131 landlords received at least one severe maladministration finding.
The most current full-sector view of complaint volumes, compensation, and severe-maladministration findings. The starting point for any board paper that asks 'how exposed are we, really?'
Note: The 131-landlords figure appears on the accompanying press release (23 September 2025): housing-ombudsman.org.uk/2025/09/23/annual-complaints-review-2/. The review landing page gives the total of 714 severe maladministration findings.
The Housing Ombudsman ordered Lewisham Council to pay a combined £40,000 in compensation across three damp and mould cases (March 2024).
A concrete example of high Ombudsman compensation against one landlord, across three cases. Use it to size the risk on long-running complaints.
Housing Ombudsman Annual Complaints Review 2024-25: 71% of complaints upheld; complaints about repairs up 43% year-on-year; 26,901 interventions made; repairs featured in 45% of high-risk cases; mid-sized landlords (1,000-10,000 homes) and local authorities struggled most with on-time complaint handling.
Shows how complaints at the Ombudsman end up. A board weighing its complaint exposure should start with the 71% upheld rate.
Housing Ombudsman Richard Blakeway's open letter to social landlords (29 November 2022) warned against blame language like 'lifestyle choices' and 'behaviours', and reinforced a zero-tolerance approach to damp and mould in the aftermath of Awaab Ishak's inquest.
The clearest official statement of the no-blame standard expected of landlords. If your case files still contain the words 'lifestyle' or 'behaviours', start by reading this.
Government and research figures on damp, mould, and housing quality.
English Housing Survey 2024 (published 29 January 2026): damp prevalence was 10% in the private rented sector, 7% in social rented housing, and 4% in owner-occupied homes.
The government's own comparison of damp by tenure. Private renting has the highest rate, at 10%.
English Housing Survey 2024: serious condensation or mould affected 6% of private rented, 5% of social rented, and 2% of owner-occupied homes.
The headline figure for the most severe category of mould in English homes. Pairs with C27 (self-reported) to show the gap between observed and lived experience.
English Housing Survey 2024: 9% of all dwellings in England have at least one HHSRS Category 1 hazard - approximately 2.3 million homes.
A sense of scale for Phases 2 and 3. Roughly 2.3 million homes in England have a Category 1 hazard today, though that figure covers every tenure, owner-occupied homes included.
English Housing Survey 2024: self-reported household condensation, damp or mould affected 46% of private rented, 41% of social rented, and 22% of owner-occupied homes.
What residents themselves report, which runs much higher than the surveyor-observed figures. It's a better guide than the technical hazard count to how many reports landlords should expect.
BRE (9 November 2021): the first-year NHS treatment cost of poor housing hazards in England is £1.4 billion per year.
The number most often quoted to argue the public-health case for housing standards. Useful for board narratives that connect housing condition to NHS pressure.
BRE: Category 1 dampness hazards cost the NHS approximately £38 million per year.
Isolates damp and mould from the wider poor-housing cost figure. Smaller absolute number, but more directly attributable to the conditions Awaab's Law targets.
BRE (July 2023): remediating England's poorest housing could provide £135.5 billion in societal benefits over the next 30 years - BRE's headline framing is 'poor housing will cost over £135.5bn over the next 30 years without urgent action'. England, not UK.
The long-term economic case for investment. A useful counter to short-term cost objections in board papers and procurement business cases.
UKHSA estimates around 2 million people in England live in homes with significant damp and/or mould (3-4% of residences), with ethnic minority and disadvantaged groups disproportionately affected.
The public-health authority's own estimate. It also finds ethnic minority and disadvantaged households are disproportionately affected, so it belongs in any decision that touches your Equality Act duties.
English Housing Survey 2024-25: 75% of social renters were satisfied with their accommodation - the lowest of the main tenures (94% owner-occupiers, 81% private renters).
Social renters are the least satisfied of the main tenures, below private renters and well below owners. Worth quoting in a board paper on resident experience.
The Awaab Ishak inquiry that gave the law its name.
Awaab Ishak died on 21 December 2020 aged two at his family’s flat managed by Rochdale Boroughwide Housing, the social landlord.
The coroner's Regulation 28 report (ref 2022-0365, 16 November 2022) - the primary record of the case that gave the law its name. The right source for board briefings and staff training.
The government bodies responsible for the policy.
The responsible department is the Ministry of Housing, Communities and Local Government (MHCLG), reverted to this name on 8 July 2024. The current Secretary of State is the Rt Hon Steve Reed OBE MP.
The department that owns Awaab's Law and the broader social-housing policy agenda. The page lists the current Secretary of State and ministerial team.
Trade-body positions and sector-wide statistics.
The National Residential Landlords Association publishes guidance advising private landlords to prepare for Awaab's Law extension.
The largest UK private-landlord association telling its members the extension is coming and how to prepare.
National Housing Federation (Kate Henderson, February 2025): 'Social housing providers are committed to ensuring the failures that led to the tragic death of Awaab Ishak never happen again and that all homes are free from serious hazards.'
The trade body's on-record position on Awaab's Law. The NHF also urged government to extend the law to private rented homes 'as soon as possible'.
As of 31 March 2025, registered providers in England owned around 4.5 million social homes (2.9m private registered providers, 1.6m local authorities).
The total denominator for everything Awaab's Law applies to today. Useful for any 'how big is the affected fleet?' analysis at sector level.
There were 1,581 providers on the Regulator of Social Housing's register on 31 March 2025 - 228 local authorities and 1,353 private registered providers.
The full count of regulated landlords in England. Also tells you the local-authority versus housing-association split - useful for benchmarking against peer organisations.
