For flats, leaseholders and freeholders
Our residential fire door replacement in London swaps flat front doors that cannot be repaired for secure, certified FD30S doorsets. The old door goes out and the new one goes in on the same day.
Replacing flat front doors
Many London flats still have front doors fitted decades ago, or replaced by a past owner with a door that is not fire rated. Inspections and fire risk assessments often flag these.
Residential fire door replacement gives you a door that protects the shared stairs, keeps your home secure and comes with proof of its rating.
We protect the hall and landing, take out the old door and frame, and fit the new doorset. Locks, seals and the closer are set before we leave.
You get new keys the same day. Your home is never left without a lockable door overnight.
Need doors replaced in a workplace or larger block? Our London fire door replacement service handles those as well.
Doors in period houses or odd-sized openings may need made-to-measure residential fire doors instead.
Signs to look for
Some faults can be repaired. These ones usually mean the door has to be replaced.
If there is no label and no paperwork, nobody can show the door is a fire door. Most freeholders will ask for it to be replaced.
Decorative glass that is not fire rated.
Doors bent by damp or heat no longer fit the frame, so gaps and seals fail.
Many filled and refilled holes from past locks weaken the door.
A frame split by a break-in cannot hold the door safely in a fire.
Gaps that cannot be closed with lipping.
How it works
From the first measure to new keys in your hand.
Most leases need the freeholder’s permission. We can send them the door spec.
We measure the opening and help you pick a style and hardware.
Old door and frame out, new doorset in.

Failed doors swapped in these buildings as well.
On the day
We arrive in the morning and leave you with a secure, working fire door the same day.
Mistakes to avoid
A new door can still fail if the wrong door is chosen or it is fitted badly. These are the mistakes to avoid.
Many front doors sold online look solid but are not fire doors. Always check for a label and test evidence.
Closers left off because residents dislike them.
A standard letter plate cut into a fire door lets fire and smoke straight through.
The old frame kept to save money.
Doors fitted without permission may have to be changed again at the owner’s cost.
Seals skipped because the door was tight.

What residents, landlords and freeholders ask about replacing flat doors.
A supplied and fitted FD30S doorset usually costs £1,100–£1,900, before VAT. The final price depends on the lock, letter plate, glass and finish you choose. Taking away the old door is included. If you are replacing several flat doors in the same building, the price per door is usually lower.
It depends on your lease. Where the leaseholder owns the door, they normally pay. Where the freeholder owns it, the cost often goes on the service charge. Check the lease or ask your managing agent before ordering. If the lease is unclear, get advice before work starts, so the cost can be shared fairly.
In most cases, yes. Leases usually need the freeholder’s written consent, and listed buildings may need council consent too. Getting permission first avoids having to change the door again later. We can send the door’s details and test evidence to your freeholder to help with the consent.
Look for a label or plug on the top edge or hinge edge of the door. You may also have paperwork from when it was fitted. If there is neither, an inspection can help, but the door may need replacing.
Usually not. A fire door is tested with its frame, so the safest option is a full doorset. If your frame is sound and matches the door’s test evidence, a new leaf may be possible, but this is less common for front doors.
You will not be. We remove the old door and fit the new one on the same day. You get new keys before we leave. Most replacements take about a day, starting in the morning and finishing by late afternoon. We tidy up before we leave.
Yes, within reason. Fire doors come in many styles and colours. Some freeholders set a style for the whole building, so check that first. We can show you options that meet both. Glazed, panelled and flush styles are all available, in many colours.
Yes. Many FD30S doorsets are also tested for security. We fit fire-rated locks, and multi-point locks are available on some doors. Ask us if security is a big concern. A spyhole and door chain can also be fitted, as long as they are fire rated and suit the door.
Older flats often have taller or wider openings. In that case, a made-to-measure fire door is built to the exact size. It takes a little longer but fits properly. We measure every opening before ordering, so you know which type of door you need.
You get photos of the door and its label, the door’s rating and maker, and a fitting record. Send a copy to your freeholder or agent, and keep one for when you sell. Good records can also help if you remortgage, as lenders sometimes ask about fire safety.
