I want to walk you through this properly because damp and mold genuinely affect your health, not just your walls, and I think too many students sit on this problem for months simply because they don't know what to actually do about it.

Report It in Writing, Straight Away
I'd tell you to report any damp or mold to your landlord or letting agent in writing; email works well since it creates a timestamped record. I'd describe specifically where it is and how it's spreading and include photos. I'd avoid relying on a verbal conversation alone, since you'll want this documentation if things don't get resolved quickly.
What Your Landlord Is Actually Required to Do Right Now
I want to be precise with you about where things currently stand, because this is genuinely an area of UK law that's shifting. A new set of protections called Awaab's Law came into force for social housing landlords from 27 October 2025, requiring them to investigate damp and mold reports within fixed timeframes and act quickly on serious hazards. However, I'd be straightforward with you: Awaab's Law doesn't yet apply to private landlords, and as of now no implementation date for the private rented sector has been confirmed, with an extension not expected before 2027.
That doesn't mean your private landlord has no obligations, though. Private landlords are already required under Section 11 of the Landlord and Tenant Act 1985 to keep the structure and key installations of your home in repair, and the Homes (Fitness for Human Habitation) Act 2018 means your home must be fit to live in throughout your tenancy; serious damp or mold can make a property legally unfit. I'd treat these as your real, current legal footing if you're in a private rental.
Give a Reasonable Timeframe, Then Escalate
I'd give your landlord a clear, reasonable window to respond; I'd say one to two weeks for a non-urgent issue and immediately for anything posing a genuine health risk. If nothing happens, I wouldn't just keep waiting.
Escalating to Your Local Council
I'd contact your local council's environmental health team if your landlord ignores the issue. Councils can assess hazards under the Housing Health and Safety Rating System and can serve an improvement notice requiring the work, with civil penalties of up to £7,000 for non-compliance, rising significantly for serious or repeated breaches. I'd tell you this is a genuinely powerful, free route and one I'd use without hesitation if your landlord is dragging their feet.
What I Wouldn't Recommend
I'd specifically caution you against withholding rent as a response to unresolved dampness or mold. I know it feels like the obvious leverage, but it can put you at legal risk yourself and doesn't remove your obligation to pay. I'd pursue the formal routes above instead.
What Causes Damp in the First Place
I'd want you to understand the difference between condensation (caused by everyday living, cooking, showering, and drying clothes indoors without ventilation) and structural damp (caused by a building defect, like a leak, poor insulation, or a failing damp-proof course). Your landlord is responsible for fixing structural causes; you're expected to manage everyday condensation through reasonable ventilation. I'd flag this distinction because landlords sometimes try to blame "lifestyle" for what's actually a structural issue don't accept that explanation without a proper investigation.
My Damp and Mould Escalation Path
| Step | What I'd Do |
| Document | Photos, written report to landlord, keep a timeline |
| Give a reasonable window | 1-2 weeks for non-urgent, immediate for serious health risk |
| Escalate | Contact local council environmental health team |
| If unresolved | Consider a disrepair claim or report to a tenancy deposit scheme if it affects your deposit dispute |
My Honest Bottom Line
I'd tell you that while Awaab's Law's strict timeframes don't yet cover private renters, you're not without protection. Document everything, give your landlord a fair but firm window to act, and use your council's environmental health team if they don't. I genuinely think most landlords respond once a council gets involved, simply because the penalties are real.
Frequently Asked Questions
Does Awaab's Law apply to my private rented flat in London?
Not yet. It currently applies only to social housing, and no date has been confirmed for extending it to private renters, with this not expected before 2027. Your private landlord is still bound by existing repair and habitability laws in the meantime.
What is my landlord legally required to do about mould in my private rental?
Under Section 11 of the Landlord and Tenant Act 1985 and the Homes (Fitness for Human Habitation) Act 2018, your landlord must keep the property's structure in repair and ensure it's fit to live in, which serious damp or mould can breach.
What should I do if my landlord ignores my mould report?
I'd escalate to your local council's environmental health team, who can investigate and serve an improvement notice with real penalties if your landlord doesn't comply.
Should I stop paying rent if my landlord won't fix the mould?
I genuinely wouldn't. Withholding rent can put you at legal risk and doesn't resolve the issue. I'd pursue the council escalation route instead.
Is condensation the same as damp my landlord must fix?
Not necessarily. Condensation from everyday living is partly your responsibility to manage through ventilation, while structural damp caused by a building defect is your landlord's responsibility to fix. I'd push for a proper investigation rather than accepting a "lifestyle" explanation without evidence.

Key Takeaways
- Awaab's Law's strict timeframes currently apply only to social housing; private renters aren't yet covered, with no confirmed date for that to change.
- Your private landlord still has real legal obligations under existing repair and habitability law to address serious damp and mould.
- Document everything in writing, give a reasonable window to respond, then escalate to your council's environmental health team if nothing happens.
- I'd never recommend withholding rent as a response; it carries real risk for you and doesn't resolve the underlying issue.
- Push back if your landlord blames "lifestyle" condensation without investigating whether the real cause is structural.
