Getting flat entrance fire doors right in City of Westminster
If you need flat entrance fire doors in City of Westminster, we can survey, supply and install, then leave you the evidence your fire risk assessor will ask for.
Fire doors in City of Westminster protect escape routes in schools, converted flats and purpose-built blocks of flats alike. We adapt the programme to the building and its occupants, never the standard of the installation.
We work with freeholders, managing agents and individual leaseholders in City of Westminster, whoever is responsible for the doors under the lease. In a block of flats in City of Westminster, each flat's front door is what keeps smoke out of the shared corridor, which is why a working closer matters as much as the door.
Why flat front doors matter so much
In most blocks the fire strategy relies on each flat containing a fire for long enough that other residents can stay put or leave safely. The flat entrance door is the barrier that makes that work. A door without a working closer, with a missing seal or with a non-fire-rated letterplate can let smoke into the corridor within minutes.
In England, regulation 10 of the Fire Safety (England) Regulations 2022 asks responsible persons in residential buildings above 11 metres to use best endeavours to check flat entrance doors at least every 12 months. Rules differ in Wales, Scotland and Northern Ireland; our guide to the regulations for flats sets them out.
What you get:
- Survey of door, frame, threshold and ironmongery
- Intumescent and smoke seals, threshold set to evidence
- Certified FD30S doorset in timber or composite
- Viewer, numerals and security hardware within the certification

Common questions
Do you work in City of Westminster?
Yes, we take on flat entrance fire doors in City of Westminster and the surrounding area, including Pimlico and London. Send your postcode and a few details and we'll come back with survey dates.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
Can residents choose the colour of their front door?
Often, within the range the doorset manufacturer offers and within any rules the freeholder sets for the corridor. Factory finishes are better than site painting, which can clog seals and hide labels.
Can a flat door have a letterbox?
Only if the letterplate is covered by the doorset's test evidence. A standard letterplate cut into a fire door breaks the rating. Many managing agents choose external post boxes instead.
