How to use AI to write to your landlord about damp and mould (UK)
Black spots on the bedroom wall, a musty smell, windows streaming every morning – damp and mould get worse as the weather turns cold, and they can harm your health. If you rent, your landlord usually has to find the cause and fix it, but first they need to hear about it in writing. A free AI chatbot can help you write a clear, calm letter in a few minutes. This guide gives you copy-and-paste prompts, what to record, what to keep private, and where to go in England, Scotland, Wales and Northern Ireland if nothing happens.

What AI can (and can't) do for a damp and mould problem
- It can turn your notes into a clear letter or email, put dates in order, describe the effect on your household, make an angry message calmer, draft a follow-up or formal complaint, and explain housing jargon in plain English.
- It can't inspect your home, tell you what is causing the damp, decide who is legally responsible, or know the latest rules where you live. It can also make up laws, deadlines and case names that sound real but aren't.
- It isn't a housing adviser or a solicitor. For your rights, use the official and charity sources further down this page.
Think of it as a patient friend who is good with words: AI helps you write it down clearly, you check the facts and send it.
Which free chatbot to use
Any of the big free chatbots will do. Pick the one you already use:
- ChatGPT – a good all-rounder on the web and in the free app. New to it? See our beginner's guide to ChatGPT.
- Microsoft Copilot – free, and handy if you write letters in Word or Outlook.
- Google Gemini – free with a Google account, and handy if you use Gmail or Google Docs.
- Claude – free tier, good at calm, clear writing.
You don't need a paid plan. Writing a letter fits easily within the free versions. Wondering whether paying is ever worth it? See our free vs paid guide.
Keep your details private
The chatbot only needs a description of the problem, not who you are. Never type or upload:
- Your name, address or postcode, or your landlord's or agent's details.
- Your tenancy reference, rent account number, or bank details.
- Your tenancy agreement, letters from your landlord or medical letters – they're full of personal information.
- Details of anyone's health beyond what you need, such as names of children or medical records.
- Photos that show faces, children, post, documents or the outside of your home.
Tip: ask the chatbot to use placeholders like [MY NAME], [MY ADDRESS] and [LANDLORD NAME], then fill them in yourself after you've copied the letter into your email or word processor.
Many chatbots let you switch off using your chats to train their AI in the settings. More tips in our AI safety guide.
Before you write: gather your evidence
A letter is much stronger with dates and evidence. Before you start, jot down:
- Where the damp or mould is (which rooms, which walls, on clothes or furniture) and roughly how big it is.
- When you first noticed it, and when you first told your landlord or agent – by phone, email, app or in person.
- What you've already done, such as opening windows, using extractor fans and wiping condensation.
- Signs of the cause you can see – a leaking gutter, a damp patch after rain, a broken extractor fan, a cold external wall.
- The effect on your household – damaged belongings, rooms you can't use, and anyone at higher risk (babies and children, older people, pregnant women, or anyone with asthma, another breathing problem or a weakened immune system).
Take dated photos of the mould and any damage, every week or two, so you can show it getting worse or coming back. Keep copies of every email and message, and write down the date and name for every phone call.
If anyone's health is affected, talk to your GP or pharmacist, or call NHS 111. A GP letter can also support your case.
The main prompt: report damp and mould to your landlord
Copy this, fill in the [brackets] and send:
“Help me write a clear, polite but firm letter to my [private landlord / letting agent / council / housing association] in the UK reporting damp and mould in my home. Facts: there is [black mould on the bedroom wall and ceiling, about the size of a pillow], and [damp patches by the living room window]. I first noticed it in [month and year] and first reported it on [date] by [phone/email], but [nothing has been done / someone visited on [date] and only painted over it]. We have tried [opening windows daily, using the extractor fan, wiping condensation each morning]. It is affecting us because [my 2-year-old has asthma / clothes in the wardrobe have gone mouldy / we can't use the back bedroom]. Ask them to: 1) arrange an inspection to find the cause; 2) tell me in writing what they found and what work they will do and when; 3) fix the cause, not just treat the mould; 4) put right any damage. Ask for a reply within [14] days. Use [MY NAME], [MY ADDRESS] and [LANDLORD NAME] as placeholders. Keep it under 300 words, in plain British English. Don't quote any laws or invent any facts – I'll add those myself if I need to.”
Then keep going: “Make it shorter”, “Make it less angry” or “Turn this into a numbered list of dates.”
Check before you send. Read every line. Make sure the dates and details are right, delete anything you aren't sure of, and add your real name and address yourself. Send it in writing – by email, through your landlord's online repairs form or app, or by post with proof of posting – and keep a copy.

If you rent from a council or housing association (England): Awaab's Law
Since October 2025, Awaab's Law has set legal deadlines for social landlords in England. It is named after Awaab Ishak, a two-year-old who died in 2020 after long-term exposure to mould in his family's housing association flat in Rochdale. Government guidance for tenants says:
- Emergency hazards must be investigated and made safe within 24 hours.
- Significant damp and mould hazards must be investigated within 10 working days of being reported, and made safe within 5 working days of the investigation finishing.
- You should get a written summary of what they found within 3 working days of the investigation finishing.
- If your home can't be made safe in time, your landlord must offer you somewhere suitable to stay, for free, until it is.
Working days don't include weekends or bank holidays. More hazards, such as excess cold and electrical hazards, are being added in phases, so check the latest on GOV.UK (search “Awaab's Law guidance for tenants”).
“Add a short paragraph to my letter asking my [council / housing association] to confirm whether they are treating this as a significant damp and mould hazard under Awaab's Law, and to send me the written summary of their investigation. Don't add any other legal points.”
If you rent privately
- Your landlord usually has to fix problems that cause damp, such as leaking pipes, roofs and gutters, broken heating, faulty extractor fans they've installed, and cracked walls or rotten window frames – and keep your home fit to live in.
- Condensation: Shelter says landlords shouldn't just blame condensation without checking, tell you to paint over mould that keeps coming back, or tell you to stop everyday things like cooking or showering. If the home can't cope with everyday living, they should look at the cause, such as poor ventilation or insulation.
- Awaab's Law isn't in force for private renters yet. The Renters' Rights Act 2025 allows it to be extended to private rented homes in England, and the government is consulting on how and when. Don't let a chatbot tell you it already applies.
- Section 21 has gone in England. Since 1 May 2026, private landlords in England can no longer use “no-fault” Section 21 evictions. If you're worried about losing your home, get advice before you act.
- Letting agent ignoring you? Ask for its complaints policy. Letting agents in England must belong to a government-approved redress scheme, which you can complain to if the agent doesn't sort it out.
No reply or no repair? What to do next
If your landlord doesn't reply or the work isn't done, follow up in writing. Ask the chatbot:
“Write a short, firm follow-up to my landlord. I reported damp and mould in writing on [date] and [had no reply / they visited on [date] but nothing has been fixed]. Since then [the mould has spread to the hallway / my son's asthma has got worse]. Ask them to treat this as a formal complaint under their complaints procedure and to give me a date for the repair within [7] days. Use placeholders for my personal details. Don't quote any laws.”
- Council or housing association tenants in England: use your landlord's complaints procedure. If you're not happy with its final response, you can go to the free Housing Ombudsman Service.
- Private tenants in England and Wales: contact your council's environmental health or private housing team (search your council's website). They can inspect your home and make the landlord carry out repairs.
- Scotland: private landlords must meet the Repairing Standard, which includes the home being substantially free from damp and mould. If your landlord doesn't act after you've told them in writing, you can apply to the First-tier Tribunal for Scotland (Housing and Property Chamber). Council and housing association tenants can complain to their landlord and then to the Scottish Public Services Ombudsman.
- Wales: under the Renting Homes (Wales) Act, your landlord must keep your home fit to live in, and damp and mould are among the things that count. Council and housing association tenants can complain to the Public Services Ombudsman for Wales.
- Northern Ireland: Housing Executive and housing association tenants can use their landlord's complaints process and then the NI Public Services Ombudsman. Private tenants can contact their council's environmental health team.
Free advice: Shelter (England), Shelter Scotland, Shelter Cymru and Housing Rights (Northern Ireland) have free advice online – Shelter England also has letter templates – and Citizens Advice can help too. Get advice before you stop paying rent, move out or take legal action – doing these the wrong way can put your home at risk.
Rules and deadlines change, so check the official website before you act. Our guide to writing a complaint letter with AI has more prompts and UK escalation routes.
Keep warm and keep mould down
While you wait for repairs, these steps from Shelter and the NHS can help with condensation – they won't fix a leak or a structural problem, and you shouldn't have to put up with mould that keeps coming back:
- Open windows for a while each day if you can, and use extractor fans when cooking and showering.
- Cover pans, close internal doors when you cook or shower, and wipe condensation off windows each morning.
- Leave a gap between furniture and outside walls.
- Dry clothes outdoors or in a vented tumble dryer where possible.
- Keep your home warm enough – the NHS advises at least 18°C in the rooms you use, especially if you're over 65, have a health condition or have a baby at home. Cold homes get more condensation.
“I'm a UK renter with condensation on my windows every morning and a small budget. Suggest 10 free or cheap ways to reduce condensation and keep warm this winter, and explain which problems I should report to my landlord instead of fixing myself.”

Watch out for scams and cowboy firms
Damp is a common hook for cold callers and online adverts – and AI makes fake adverts, “free survey” offers and reviews look more convincing.
- Be wary of anyone who knocks on your door or messages you offering a free damp survey and then pushes expensive treatment the same day.
- If you rent, repairs are usually your landlord's job – don't pay a firm yourself without getting advice first.
- Never give bank details or a one-time passcode to someone who contacts you out of the blue claiming to be from the council, a “government grant scheme” or your landlord.
Check it yourself: contact your council or landlord using details you've found yourself, not those in the message.
- Forward scam texts free to 7726, and suspicious emails to [email protected].
- Report fraud to Report Fraud (reportfraud.police.uk, 0300 123 2040) in England, Wales and Northern Ireland, or to Police Scotland on 101.
- If you've given out bank or card details, call your bank straight away – you can dial 159 to reach many UK banks safely.

Frequently asked questions
Can ChatGPT write a letter to my landlord about damp and mould?
Yes. The free versions of ChatGPT, Microsoft Copilot, Google Gemini and Claude can turn your notes into a clear, polite letter or email that reports damp and mould, says when it started and how it affects your household, and asks for an inspection and a repair date. Use placeholders for your name and address, check every fact, and don't let it quote laws you haven't checked.
What is Awaab's Law?
Awaab's Law sets legal deadlines for social landlords (councils and housing associations) in England to deal with serious hazards. Since October 2025 it has covered emergency hazards and significant damp and mould: emergency hazards must be investigated and made safe within 24 hours, and significant damp and mould must be investigated within 10 working days of being reported and made safe within 5 working days of the investigation finishing. More hazards are being added in phases.
Does Awaab's Law apply to private renters?
Not yet. The Renters' Rights Act 2025 lets the government extend Awaab's Law to private rented homes in England, and it opened a consultation on how and when to do this in October 2026. Until it comes in, private landlords still have to keep the structure, heating and water in repair and keep the home fit to live in, and your council can inspect and order repairs.
My landlord says the mould is just condensation. What can I do?
Ask them to find out why the home can't cope with everyday living, such as cooking, showering and drying clothes. Shelter says landlords should not just blame condensation without checking, or tell you to paint over mould that keeps coming back. Keep doing what you reasonably can to ventilate, keep dated photos, and if nothing changes, follow the complaint and council routes in this guide.
Can my landlord evict me for complaining about damp?
In England, private landlords can no longer use Section 21 'no-fault' evictions since 1 May 2026, so they need a valid legal reason to end your tenancy. If you're worried about losing your home, get free advice quickly from Shelter or Citizens Advice before you do anything else.
Should I upload photos of the mould to a chatbot?
You don't need to. The chatbot only needs a description: where the mould is, how big, and how long it's been there. Send your photos to your landlord, not the chatbot. If you do upload one, make sure it shows no faces, children, post, documents or anything that identifies your address.
