Fire door compliance is not a grey area. Landlords who fail to install, maintain or inspect fire doors in HMOs and multi-occupied buildings face criminal prosecution, unlimited fines and — since the Renters Rights Act 2025 — Rent Repayment Orders where tenants can reclaim months of rent.
The Legal Framework — Three Pieces of Law Apply
- Regulatory Reform (Fire Safety) Order 2005 (as amended): Applies to all non-domestic parts of residential buildings (communal areas, escape routes)
- Housing Act 2004: Applies to HMOs via licensing conditions
- Fire Safety (England) Regulations 2022: Added specific fire door inspection duties
What Are the Maximum Fines?
| Offence | Maximum Penalty |
|---|---|
| Failure to carry out fire risk assessment | Unlimited fine + 2 years imprisonment |
| Non-compliant fire doors (communal areas) | Unlimited fine |
| Failure to carry out quarterly fire door inspections (11m+ buildings) | Unlimited fine |
| Unlicensed HMO | Unlimited fine + Rent Repayment Order |
| Breaching HMO licence conditions (inc. fire doors) | Up to £9,000 |
| Failing to register with Property Portal | Up to £2,250 |
The Cost of Getting It Right vs Getting It Wrong
A typical HMO fire door costs £115–£195 to supply and fit professionally. A prosecution, fine and legal costs can run to tens of thousands of pounds — not including the reputational damage and potential imprisonment for serious breaches.
The cheapest fire door compliance is always the proactive kind — installed correctly before a council inspection, not reactively after one.
