If you manage property in Wales and you have read that the Decent Homes Standard now applies to you, or that Awaab's Law gives you 24 hours to investigate a damp report, you have been reading guidance written for England. Some of it was not even correct about England.

But the correction that most articles stop at is only half right, and the half they leave out is the half with a live deadline in it. Wales does have hazard response timescales. They came into force on 1 April 2026. They apply to social landlords, not private ones, and they sit in a completely different instrument from the English rules.

Here is what actually applies on each side of the border, and to which landlords.

The Short Answer

Two of those are English regimes that do not cross into Wales. Two are Welsh regimes that do not cross into England. Nothing about the labels tells you that, which is why the confusion is so persistent.

There is a second layer of confusion sitting on top. A provision existing in an Act is not the same thing as a provision being in force. Much of the Renters' Rights Act reporting has collapsed those two ideas, which is why English landlords have also been told to prepare for standards that have not commenced.

What Does Not Apply in Wales

• The Decent Homes Standard:
  This is an English measure that applies to social housing. The Renters' Rights Act 2025 provides for extending it to the English private rented sector, but that has not been brought into force and the timetable follows a consultation. A great deal of guidance published in early 2026 announced it as a live England-and-Wales change. It is neither live nor Welsh.

   

• Awaab's Law:
  This originates in the Social Housing (Regulation) Act 2023, which inserted a new duty into the Landlord and Tenant Act 1985. Regulations brought it into force for English social landlords on 27 October 2025, covering emergency hazards and significant damp and mould hazards, with further hazard categories phased in during 2026 and 2027. The Renters' Rights Act 2025 contains a power to extend it to the English private rented sector. That power has not been exercised and no commencement date has been confirmed. Housing is devolved, and none of it reaches Wales.

The practical harm here runs both ways. A Welsh private landlord reading English coverage believes a statutory clock is running that is not. A Welsh contract-holder reading the same coverage believes they have a fixed-timescale remedy that does not exist in their tenure. Both are working from the wrong rulebook.

What Applies to Private Landlords in Wales

Wales reaches the same subject matter through the occupation contract rather than through a duty imposed from outside it.

Section 91 of the Renting Homes (Wales) Act 2016 implies into every occupation contract a term that the dwelling is fit for human habitation. Section 92 implies the obligation to keep the structure and exterior in repair, along with the installations for the supply of water, gas and electricity, and for sanitation, space heating and heating water. These are contractual terms, enforceable by the contract-holder as a breach of contract.

Fitness is judged against the Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022. Regulation 3 requires regard to be had to the presence or occurrence, or likely presence or occurrence, of the 29 matters and circumstances listed in the Schedule, which cover damp and mould growth, excess cold and heat, electrical hazards, fire and much else.

On top of that assessment, regulations 5 to 8 impose three hard requirements. Fail any of them and the dwelling is treated as unfit for human habitation, without any further assessment:

Two details that catch people out. A battery smoke alarm does not satisfy regulation 5, because the alarm must be connected to the electrical supply and interlinked. And where investigatory or remedial work is carried out on the electrical service installations between inspections, the landlord must give the contract-holder written confirmation that the work was done. The Welsh Government's guidance for landlords is explicit that the whole regime is preventative in purpose, not a checklist to satisfy after a complaint.

Note also that regulations 5 to 8 apply only to the contract types listed in regulation 4. The transitional period that once delayed these requirements for converted contracts has long passed, so if you are still treating them as future obligations, you are years behind.

There Is No Statutory Clock, and That Is Not the Relief It Sounds Like

Wales imposes no fixed timescale on a private landlord to investigate or remedy a hazard. The test is the general one: a reasonable time from when you knew, or ought to have known, of the disrepair or unfitness.

Landlords tend to hear that as latitude. It is closer to the opposite. A fixed statutory deadline tells you exactly what compliance looks like. A reasonableness standard is decided after the fact, by a court, on the specific facts, with the benefit of hindsight and a contract-holder's timeline of unanswered messages. What "reasonable" means for a leaking roof in January is not what it means for a cracked tile in June.

Which makes the dated record the whole ballgame. When the report arrived, what you did, when the contractor attended, what they found, what was done next. An auditable maintenance record across the portfolio is not administrative tidiness in this regime. It is the evidence the reasonableness question turns on.

What Applies to Social Landlords in Wales

This is the part missing from almost every article that correctly says Awaab's Law does not apply in Wales.

Welsh Government did respond to the death of Awaab Ishak. It did so by consulting on, and then adding, a Hazard Response Rule as an addendum to the Welsh Housing Quality Standard 2023. It came into force on 1 April 2026 and it carries real timescales:

Where it is not possible to remedy within those timescales, the social landlord must send the tenant a written summary plan within five working days. Compliance is monitored through a quarterly return, the first of which fell due at the end of June 2026, and landlords are expected to publish their response times and report on performance as part of the WHQS compliance return.

So the accurate statement is not "Wales has no Awaab's Law." It is that Wales built its equivalent inside the social housing standard rather than in statute, applied it to social landlords only, and left the private rented sector on the fitness for human habitation regime with no fixed clock.

Welsh Government has said the private sector position is under consideration. Nothing has been made.

The Two Different Twenty-Nines

A genuine trap, and one worth knowing if you operate across both tenures in Wales.

The fitness for human habitation regime has 29 matters and circumstances, set out in the Schedule to the 2022 Regulations, and it governs occupation contracts. The Housing Health and Safety Rating System, introduced by the Housing Act 2004, assesses 29 categories of housing hazard, and it is what feeds WHQS compliance, where any element with a Category 1 hazard automatically records the dwelling as failing.

Both are 29. They are related, they overlap heavily in subject matter, and they are not the same list operating under the same regime. If you manage a mixed portfolio, do not let a single spreadsheet column pretend they are interchangeable.

What to Do

1. Establish which regime each property sits in:
   Private lettings in Wales run on fitness for human habitation. Social stock runs on WHQS, including the Hazard Response Rule, alongside the fitness duty that applies to occupation contracts generally. Mixed portfolios need both, tracked separately.
   
   
2. Audit the three hard requirements across every private let:
   Interlinked mains-connected smoke alarms on each storey, carbon monoxide alarms in every room with a qualifying appliance, and a valid electrical condition report with a copy issued to the contract-holder. Any gap means the dwelling is treated as unfit, whatever its actual condition.
   
   
3. Check whether your interim electrical work was documented to the contract-holder:
   This is the most commonly missed obligation in the whole regime, because the work itself gets done and the written confirmation does not get sent.
   
   
4. Date-stamp everything on the private side:
   Hazard reported, acknowledged, inspected, quoted, fixed. In a reasonableness regime, an undated recollection is worth close to nothing. Portfolios that keep property and maintenance records in one system can reconstruct a timeline in minutes; portfolios spread across inboxes and phone calls generally cannot.
   
   
5. If you hold social stock, confirm your quarterly return is in hand:
   The rule has been live since April and the first return was due at the end of June.
   
   
6. Stop reading English guidance for Welsh properties, and check commencement even when you are reading about England:
   This is the root cause of both errors. Anything referencing the Decent Homes Standard, Awaab's Law, Section 21 or assured shorthold tenancies is England material and does not govern your Welsh portfolio. And a reform announced in an Act is not a reform in force.

The Wider Picture

Four nations, four regimes, and they are diverging rather than converging.

England has Awaab's Law in social housing and has legislated to extend both it and the Decent Homes Standard to the private rented sector, though neither extension is yet in force. Wales has fitness for human habitation across all occupation contracts and hazard timescales in social housing only. Scotland has its own approach in progress, with regulations proposed to impose investigation and repair timescales on both social and private landlords from October 2026. Northern Ireland is different again.

The same border logic governs possession and contract paperwork, not just standards. Wales runs its own occupation contract regime with its own deadlines and its own compensation, most recently the [written statement changes that took effect on 1 June 2026](INTERNAL LINK: add slug at publish).

For anyone operating across borders, the sensible planning assumption is that a compliance process built for one nation will be wrong in the others, and that the gap will widen. The instinct to write one policy and apply it everywhere is exactly the instinct that produces the Decent Homes error.

Conclusion

The correction is easy to state. The Decent Homes Standard and Awaab's Law are English measures, neither applies in Wales, and the private rented sector extensions have not commenced even in England.

The more useful point is that Wales did not simply decline to act. It regulates property condition through the occupation contract, with an implied fitness term, 29 matters and circumstances, and three specific requirements that render a dwelling unfit on their own if breached. And it did respond to Awaab Ishak, through the Welsh Housing Quality Standard, with timescales that have been binding on social landlords since April.

The risk for a Welsh landlord is not that the rules are lighter. It is that they are differently shaped, so English guidance produces confident compliance with the wrong regime. A private landlord in Wales who spends six months preparing for a Decent Homes assessment that will never come, while running battery smoke alarms and an expired electrical condition report, has a property that is already treated as unfit for human habitation.

Work out which regime you are in first. Everything else follows from that.

Frequently Asked Questions

1. Does the Decent Homes Standard apply to my Welsh rental property?
No. It is an English standard for social housing, with extension to the English private rented sector legislated for but not yet in force. Wales regulates condition through the fitness for human habitation duty under the Renting Homes (Wales) Act 2016.

2. Does Awaab's Law apply in Wales?
No. It applies to English social landlords. Its extension to the English private rented sector is a power in the Renters' Rights Act 2025 that has not yet been commenced. Welsh social landlords are subject to a comparable Hazard Response Rule under WHQS 2023 from 1 April 2026. Welsh private landlords are not subject to fixed statutory timescales.

3. How long do I have to fix damp and mould in a private let in Wales?
There is no prescribed period. The obligation is to act within a reasonable time of knowing or being expected to know, judged on the facts. Treat urgency as a function of the risk to the occupier, and keep dated records.

4. Are battery smoke alarms acceptable in Wales?
Not for contracts caught by regulations 5 to 8. The alarms must be on each storey, in repair and proper working order, connected to the electrical supply, and interlinked. A non-compliant dwelling is treated as unfit for human habitation.

5. How often do I need an electrical inspection?
At intervals of five years or less, by a qualified person, or sooner if the condition report specifies an earlier date. The contract-holder must be given a copy of the report, and written confirmation of any investigatory or remedial work carried out between inspections.

Important Notice

This article applies to Wales only. Housing law is devolved and the position differs in England, Scotland and Northern Ireland. Wales operates under the Renting Homes (Wales) Act 2016, which uses occupation contracts and contract-holders rather than tenancies and tenants. The Decent Homes Standard and Awaab's Law are English measures and do not apply in Wales.
