Awaab’s Law replaces a landlord’s judgement about how urgent a repair is with a legal deadline. It has applied to social housing in England since 27 October 2025, and the Renters’ Rights Act 2025 provides for extending it to the private rented sector. No date has been set for private landlords yet.
For a private landlord the change will not be that damp becomes your problem, because it already is. The change is that once the extension is made, the clock will start when the landlord becomes aware of the hazard, whether through a tenant’s report or otherwise, and missing the deadline will become a breach rather than a complaint.
In short
- Awaab’s Law has applied to social housing in England since 27 October 2025; the Renters’ Rights Act allows it to extend to private renting.
- No date has been set for private landlords, though the social sector timescales are a reasonable planning guide.
- In social housing, significant damp must be investigated within 10 working days and made safe within 5 working days of the investigation finishing.
- Damp concentrates in solid wall construction with no cavity to insulate, converted flats with poor ventilation, and buildings where previous work sealed them up.
- An independent damp survey is now essential due diligence on pre-1919 or solid wall purchases.
What Awaab’s Law requires
The law works by writing fixed timeframes into the tenancy itself, so a hazard the landlord becomes aware of triggers a duty to investigate and then to act within a set number of days. In the social sector those requirements sit in the Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025, and the government’s own guidance sets out what each stage demands.
The important structural point is that the duty attaches to the landlord’s awareness, not to their assessment of whether the concern is reasonable. Awareness can come from a tenant, but it can equally come from an inspection, a contractor or a neighbour, so no report having been made is not a defence.
That is a different operating model from the one most private landlords run, where a repair queue is ordered by whoever chases hardest.
Awaab’s Law timescales as they stand
For social landlords, from 27 October 2025, emergency hazards must be investigated and acted on as soon as reasonably practicable and in any event within 24 hours.
Significant damp and mould hazards run on a longer chain.
| Hazard / stage | Timescale |
|---|---|
| Emergency hazards | Investigated and acted on as soon as reasonably practicable, and in any event within 24 hours |
| Significant damp and mould: investigate | Within 10 working days of becoming aware |
| Written summary to the tenant | Within 3 working days of the investigation finishing |
| Property made safe | Within 5 working days of the investigation finishing |
The landlord must investigate within 10 working days of becoming aware of the issue. Within 3 working days of that investigation finishing, they must give the tenant a written summary of what was found and how the property will be made safe. The property must then be made safe within 5 working days of the investigation finishing.
The written summary is the part landlords tend to overlook, and it is the part that creates evidence.
It is a dated document, produced by you, recording that you knew. Getting the repair right but never issuing the summary still leaves a gap in the file.
The scope widens over time. From 30 November 2026 the social sector regime extends to further hazards, including excess cold and heat, falls, structural collapse, fire and electrical hazards, and a later phase planned for 2027 is set to cover the remaining hazards under the Housing Health and Safety Rating System, with overcrowding excluded.
When it will apply to private landlords
No date has been set, and anyone quoting you one is guessing.
The Renters’ Rights Act carries the power to apply Awaab’s Law to privately rented homes, and the government’s implementation roadmap places it in the third and final phase, alongside a modernised Decent Homes Standard for the sector.
The roadmap does not attach a commencement date to that phase, and the timescales for the private sector are subject to consultation.
So the position is that the power exists, the direction is settled, and the deadlines that will apply to you have not been written yet.
That is still useful rather than a reason to ignore it. The social sector version is the template the private version will be built from, and it has been running since October 2025. Treating those timescales as the likely shape of your future obligation is a reasonable planning assumption, provided you do not tell a tenant they are already the law.
What it does to older stock
This is where it stops being compliance reading and starts being a pricing question.
Damp is not distributed evenly across the housing stock. It concentrates in solid wall construction with no cavity to insulate, in converted flats with poor ventilation, and in anything where previous work sealed a building up without giving moisture a way out. That description also covers a lot of the cheap, high yielding terraced stock that looks best on a spreadsheet.
A fixed deadline changes the economics of owning that stock in two ways.
- It removes the option of deferring, because the cost lands on a date set by the moment you find out rather than by your cash flow.
- And it pushes you toward fixing the cause rather than the symptom, because a mould wash that fails in four months restarts the clock instead of closing the issue.
None of that makes older property uninvestable. It does mean the survey matters more than the yield, and that a property priced as though ventilation and damp proofing are optional is priced wrong.
What this means for property investors
Buy with the repair liability visible. On any pre-1919 or solid wall purchase, an independent damp survey, not one from a firm selling the remedial work, is now essential due diligence, because you are underwriting a future obligation with dates attached rather than a vague maintenance risk. Where a property already shows damp, the question is whether the cause is fixable and what it costs, not whether the tenant is likely to complain.
Build the process before you need it. A landlord who cannot show when they became aware, when they inspected and what they told the tenant will struggle regardless of what the final timescales say. That record keeping sits naturally alongside the compliance paperwork the PRS Database, the new national register of private landlords and their properties, will require, and alongside the Decent Homes Standard arriving in the same phase. They are one workload, not three.
