The laws affecting fire doors in London — in one paragraph each

Four pieces of legislation govern fire doors in London residential property today. They overlap; in practice you comply with all four by getting the doors and the documentation right once.

Regulatory Reform (Fire Safety) Order 2005

The primary law. Places a duty on the "responsible person" (usually the landlord or managing agent) to undertake a fire risk assessment and to maintain general fire precautions, including fire-resisting doors. Fines are unlimited and serious cases can result in imprisonment for responsible persons.

Building Regulations Approved Document B

The technical detail for new builds and material alterations. Specifies fire resistance ratings (FD30, FD60, FD90, FD120), where each is required and how compartmentation works. Existing buildings don't have to retrospectively meet Approved Document B in full, but the Fire Safety Order effectively requires the same standard for any escape-route door.

Fire Safety (England) Regulations 2022

The post-Grenfell reforms. Made quarterly fire-door checks mandatory for shared escape routes in higher-risk residential buildings, and tightened the documentation and Accountable Person regime. Through 2024 and 2025, London councils have applied the spirit of the 2022 Regulations to all licensable HMOs — not just high-rise.

Building Safety Act 2022 + Section 156

For buildings over 18m or 7+ storeys, the Building Safety Act introduced the Building Safety Regulator and the requirement for a building safety case. Section 156 expanded duties for non-domestic premises and the responsible person regime. If your block is in scope, your fire-door programme is now part of the safety case file.

Full detail of how these stack up is covered on the dedicated fire door regulations London page.

HMO landlords — what the 2025/26 rules actually mean

If your London property is licensable as an HMO (broadly: three or more tenants forming more than one household, sharing facilities), four things are now expected of your fire doors:

1. FD30S certified doors on every habitable room opening onto the shared escape route, plus on the flat-entrance door if the HMO is itself a flat.
2. Documentation pack: door certificates, installation record, photographs, ironmongery list.
3. Quarterly inspection log: every 3 months from sign-off, signed by a competent person, kept in writing.
4. Re-licensing readiness: when your borough's licence renewal lands, your evidence is current and complete.

Most London HMO landlords already do (1). The 2025/26 expectation is (2), (3) and (4). Doorz London delivers all four as a single package — see HMO fire door compliance London.

Block freeholders and managing agents

If you manage a residential block in London — particularly one over 11m — your fire-door duties are heavier because the Accountable Person regime applies. The most common compliance gaps we see in 2026:

• Pre-2018 flat-entrance doors with no documented certification trail.
• FD30S where FD60 is now expected (post-Grenfell, buildings over 11m).
• Non-fire-rated letter plates and viewers invalidating otherwise-compliant doors.
• No quarterly inspection log on the communal-side doors.
• Door programmes done piecemeal across years, with the documentation lost between contractors.

For block-level fire-door work see fire door compliance London and flat entrance fire doors London.

Flat-entrance fire doors — the single biggest compliance miss

The door between a flat and a communal corridor is the single most-frequently-failed item we see across London managing agents' portfolios. Three reasons: the door looks like a solid timber door (often it's the original from the 1960s-1980s when the block was built), the letter plate is non-rated brass, and there's no closer. All three need to be right. See the dedicated flat entrance fire doors London page for the spec council building-control teams accept.

The quarterly inspection regime

Since 2023 the Fire Safety (England) Regulations 2022 has required quarterly checks of fire doors in shared escape routes in higher-risk residential. Through 2024–2025 London boroughs have steadily extended this expectation across most licensable HMOs.

What the inspection actually looks like:

• Walk every fire door on the escape route.
• Visually inspect: certification plug, gaps, strip and seal condition, hinge condition, closer condition, latch operation.
• Test: release the door from 45°, 90° and 130° open positions and confirm it self-latches.
• Log: pass/fail per item, date, signature.
• Action: book any repairs identified within the next inspection cycle.

A typical 6-bed HMO inspection takes 30–45 minutes. We provide the template log + first signed inspection with every installation. For ongoing inspections see fire door inspection London.

Fines and prosecutions in 2026

Three enforcement routes London councils now use:

• HMO licensing civil penalty — up to £30,000 per offence under Housing Act 2004 amendments. Most-common route for HMO non-compliance.
• Improvement notices under Housing Act 2004 — requires landlord to remedy within a stated timeframe; failure to comply is itself an offence.
• Criminal prosecution under the Regulatory Reform (Fire Safety) Order — unlimited fines and imprisonment for responsible persons in serious cases (typically where a fatality occurs or where reckless non-compliance is evidenced).

Real cases from 2024–2026 are summarised in our fire door fines for London landlords guide.

Documentation you must keep

The single most-asked question in our inbox: "What documents does the council actually want to see?" Here it is, in the order it's usually requested:

1. The current fire risk assessment, signed by a competent person.
2. Door certificates — one per door type, from the manufacturer.
3. Installation record per door — fitter, date, ironmongery, signed.
4. Photographs of each fitted door at handover.
5. Ironmongery list with CE/UKCA confirmation.
6. Quarterly inspection log — current, with signed entries every 3 months.
7. Remedial works records — anything fixed since sign-off, with a record.

Doorz London delivers items 2–5 within 48 hours of any installation we do. Items 1, 6 and 7 are your responsibility, but our packages include the template for 6 and the first signed entry.
