Fire Door Installation

A fire door only works if it is fitted correctly — and most are not. We supply and install FD30 and FD60 fire doorsets across London for landlords, agents and block managers, with intumescent strips, cold smoke seals and self-closers fitted to specification, gaps gauged, and every door documented for inspection.

FD30 and FD60 Doorsets, Properly Specified

FD30 doors resist fire for 30 minutes and are the standard requirement for HMO bedroom and kitchen doors opening onto escape routes; FD60 doors give 60 minutes and appear in higher-risk locations such as doors to plant rooms or between commercial and residential parts of a building. The rating belongs to the whole assembly — leaf, frame, hinges, intumescent strips, seals and glazing — not the leaf alone. We install certified doorsets or certificated leaf-and-frame combinations, never an unrated door with strips added as decoration. Ironmongery is fire-rated and UKCA or CE marked: three hinges minimum, closers to BS EN 1154, and intumescent protection to locks and latches. Where a period property deserves it, we fit fire doors with traditional panel profiles so compliance does not cost the building its character.

Why Installation Is Everything

A fire door hung with sloppy gaps is worthless — smoke and flame pass straight around it. The workmanship tolerances are precise: a consistent 2–4 millimetre gap between leaf and frame at the head and sides, and gaps over 4 millimetres are a routine inspection failure. The threshold gap should generally not exceed 8–10 millimetres, or around 3 millimetres where cold smoke sealing is required. Our installers work to BS 8214 guidance: frames packed and fixed correctly, intumescent strips and cold smoke seals continuous and unpainted, closers adjusted so the door fully self-closes onto the latch from any angle, and no wedges, broken closers or trimmed-down leaves left behind. Each fitted door is gap-gauged and photographed before we sign it off.

Fire Door Surveys for HMOs and Blocks

Under the Fire Safety (England) Regulations 2022, responsible persons in residential buildings over 11 metres must check flat entrance doors at least annually and communal fire doors every three months. In licensed HMOs, councils inspect fire doors as a matter of routine, and damaged or wedged-open doors are among the most common licensing defects. We carry out fire door surveys across London portfolios: every door checked for certification evidence, gaps, seals, closers, hinges and glazing, with a photographic report grading each door as compliant, repairable or for replacement. Repair is often legitimate — replacing seals, adjusting closers, re-hanging a leaf — and far cheaper than wholesale replacement. The report gives landlords and agents a costed, prioritised plan rather than a scare list.

Frequently Asked Questions (FAQ)

How much does a fire door cost fitted in London?

A certified FD30 doorset supplied and installed typically costs £400–£900 per door depending on specification and finish, with FD60 doorsets from around £700–£1,300. Upgrading seals, closers and ironmongery on an existing compliant leaf costs considerably less. Multi-door HMO and block packages are priced per schedule after a survey.

Where do I need fire doors in an HMO?

Typically FD30 doors with self-closers on all habitable rooms and kitchens opening onto the protected escape route, in line with the council’s licensing standards and LACORS fire safety guidance. Requirements vary with height and layout — a three-storey HMO is treated more strictly than a two-storey house share. We confirm the exact door schedule for your borough before quoting.

My fire doors failed inspection even though they are fire doors — why?

Almost always installation defects: gaps over 4 millimetres at the leaf edge, missing or painted-over intumescent strips and smoke seals, closers removed or disconnected, or unrated hinges and glazing. The leaf itself is often fine. We re-hang, re-seal and re-certify existing doors where possible rather than defaulting to replacement.

How often must fire doors be checked?

In residential buildings over 11 metres, the Fire Safety (England) Regulations 2022 require quarterly checks of communal fire doors and annual checks of flat entrance doors. For licensed HMOs, regular documented checks are expected as a licence condition. We run scheduled survey visits for agents and block managers with a photographic report each round.
