How Much Compensation for Damp and Mould in the UK?

Short answer: Most damp and mould housing disrepair claims in England and Wales settle between £3,000 and £15,000. The bulk of the award is usually calculated as a percentage of the rent paid during the period the home was affected, typically 25% to 50%, depending on severity. The standard limitation period for bringing a claim is 6 years. Awaab's Law (in force 27 October 2025) has tightened expected landlord response times in the social-housing sector and is starting to push compensation upwards where the landlord has missed statutory deadlines.

This is a framework, not a quote. Every case turns on its facts.

What goes into a damp and mould compensation award

Awards in housing disrepair generally combine three or four elements:

1. Money back on your rent, a share of the rent you paid while the home was not fit to live in properly. Often put as "25% back for a year of mould in two rooms" or "50% back for six months where the whole flat was affected".
2. A payment for the stress and discomfort, a separate amount for the upset, the inconvenience, and any effect on your health (usually backed up by letters from your doctor and medical records).
3. The cost of what was ruined, money to replace belongings (clothes, bedding, furniture, electronics) damaged by the damp and mould, plus any money you had to spend because of it.
4. An order to fix the home, the court can order the landlord to actually carry out the repairs.

The 25% to 50% rent framing

Courts have developed an unofficial scale for how much of the rent you "did not get the benefit of" when the home was affected by damp and mould. The rough bands look like:

You then take that percentage off the rent you paid while the home was affected. So 30% off £700 a month for 18 months = £3,780 from the rent part alone, before anything for the stress or for ruined belongings is added on top.

The £3,000 to £15,000 range in practice

Most published settlement and court awards in social-housing damp and mould cases fall inside £3,000 to £15,000. Within that:

• £3,000 to £6,000 is typical where mould was in one or two rooms, lasted under a year, and there is no documented health impact.
• £6,000 to £10,000 is typical where mould was persistent, affected multiple rooms, ran for one to three years, belongings were damaged, and there is some health impact.
• £10,000 to £15,000 is typical where mould was severe and prolonged, there is documented health impact (medical records, hospital visits), and substantial belongings have been replaced.
• Above £15,000 does happen, particularly where children are affected, the landlord ignored repeated reports, or there is a clear public-record failure. Recent independent rulings show awards at this level and higher, you can see real published cases here.

The largest single damp-related case in recent UK history, the inquest into the death of 2-year-old Awaab Ishak in Rochdale, led directly to the 2023 reforms that became Awaab's Law. The personal-injury element of any case where there has been a death sits in a different legal pathway altogether (clinical negligence/Fatal Accidents Act).

You usually have 6 years to claim

For housing disrepair, the law (the Limitation Act 1980) usually gives you six years to claim, counting from when the problem started. So you can normally claim for up to six years of damp and mould, as long as you were the tenant during that time and you reported it.

A couple of exceptions:

• For the health part of a claim, the limit is three years from when you knew your health was affected.
• In Wales, the rules can be slightly different, so get advice from someone who knows the Welsh system.

How Awaab's Law affects the figure

Since 27 October 2025, social landlords in England have been required to investigate prescribed hazards (including damp and mould) inside fixed statutory timescales and to carry out emergency repairs inside 24 hours. Where a landlord misses those deadlines, that breach is now a named statutory failure rather than just a general one. Courts and independent rulings are starting to reflect that in awards, particularly where landlords missed the 24-hour emergency category.

The Renters' Rights Act 2025 is expected to extend Awaab's Law-style timescales to the private rented sector from October 2026.

What you have to prove

To get compensation you need to show:

1. The defect existed (photos, dates, contractor visits, environmental health reports).
2. The landlord was on notice (reports in writing, complaints references, emails, portal screenshots).
3. The landlord failed to put it right inside a reasonable time (the running clock between report and repair).
4. You suffered loss (rent paid during the period, damaged belongings, health impact, out-of-pocket costs).

Without "notice in writing", most cases fail. Keep records.

How a claim actually works

1. Free assessment, most CMCs and solicitors offer this. Call us on 0800 030 4669.
2. Letter of claim to the landlord.
3. Landlord investigates and usually offers a settlement.
4. Court action only if the landlord refuses to settle reasonably.

On no-win-no-fee terms the fee only comes out of your compensation if you win, never out of your own pocket. There should be no upfront cost to you.
