Today, the law got teeth. Private landlords: damp and mould is now your problem too.

As of today — 22 June 2026 — councils across England have the power to issue private landlords a £7,000 fine for failing to fix severe damp and mould. No court order. No prior warning required. Just a council inspector, an unresolved hazard, and a civil penalty notice.

This is the moment private landlords joined the same compliance environment that social housing providers have been navigating since October 2025. The stricter repair timelines are still in consultation — but the financial exposure is live today.

A £15.4 billion problem that landlords think someone else has

Damp and mould is not a niche issue. It costs the UK economy an estimated £15.4 billion every year. The NHS spends £1.4 billion annually treating people made ill by poor housing conditions — of which £895 million is directly attributable to damp, cold and mould exposure. These are not abstract figures. They are conditions in properties that someone owns and is responsible for.

The scale of the problem in the private rented sector is significant. An estimated 6.5 million UK households are dealing with damp and mould right now.

The gap between what landlords believe and what tenants experience

When landlords and tenants were asked the same question about damp and mould, their answers were very different. 43 per cent of tenants have experienced damp or mould in their rental. Only 26 per cent of landlords say they identified damp or mould in their properties. And just 18 per cent say a tenant actually complained to them about it.

Nearly half of tenants are living with the problem. Fewer than a fifth of landlords have heard about it. The gap is not because landlords are ignoring complaints — it is because tenants are not making them. Many fear eviction, fear a rent increase, or simply believe nothing will change. So the problem grows silently, in buildings their landlords believe are fine.

As of today, not knowing is not a safe position. A council inspector does not need your tenant to have complained. They need to find a Category 1 hazard.

What changed today — and what is still coming

Active from 22 June 2026: councils can issue civil penalties of up to £7,000 under the Renters' Rights Act for failure to address severe damp, mould, or any of 20 other listed housing hazards. This is enforced under the updated Housing Health and Safety Rating System (HHSRS), which also came into force today.

Already available to tenants: under the Homes (Fitness for Human Habitation) Act 2018, any tenant can take you to court directly — without waiting for council action — for compensation and a repair order. There is no cap on what a court can award.

Coming via secondary regulations: Awaab's Law repair timelines are in active government consultation for the private rented sector. When they land, they will be automatically implied into every assured tenancy agreement. The expected framework: 24 hours to make safe any emergency hazard; 10 working days to investigate a reported damp or mould hazard; 3 working days to give the tenant a written summary; 5 working days to begin physical repair works.

The penalty tiers

• £7,000 council civil penalty — active today — for failure to fix a serious hazard.
• £40,000 escalated civil penalty for repeated or serious breaches under the Renters' Rights Act.
• Criminal prosecution for persistent non-compliance or deliberate neglect.

Missing a deadline once becomes an audit trail entry. Missing it twice becomes a referral for escalated enforcement. Once Awaab's Law timelines are extended to the private sector, every missed deadline is also a breach of contract — giving your tenant a direct civil claim against you.

What you can do today

• Audit proactively. Walk every property every three to six months. Blocked gutters, failed extractor fans, poor insulation, minor leaks — these create the conditions for damp long before mould appears. The problem you catch early is the one you fix cheaply.
• Make it easy to report. The compliance clock starts the moment you are notified. A simple, accessible reporting channel — text, WhatsApp, an online form — removes the barrier that stops tenants telling you there is a problem.
• Document everything. Date-stamped records, photographs, contractor confirmations. An email chain is not enough.
• Consider continuous monitoring. Sensor data that reads temperature, humidity and moisture levels gives you the picture a six-monthly walkthrough cannot. The at-risk property shows up on a dashboard before a tenant has to complain — and before a council inspector has to find it.

The direction of travel is clear

Private landlords have watched Awaab's Law from a distance since it was named after Awaab Ishak, the two-year-old who died in 2020 from a respiratory condition caused by mould in his family's social housing flat in Rochdale. That distance closed today.

The repair clock, the evidence requirements, the financial penalties — these are the new operating environment for private rented housing in England. The landlords who treat this as a compliance exercise to be managed will find it expensive. The ones who treat it as an opportunity to know their stock properly will find it manageable.
