Specialist fire door fitters
We handle fire door installation in London from survey to sign-off. Our fitters install certified doorsets exactly as the test evidence says, so each door performs as it was tested.
Fire door fitting explained
Fire door installation means fitting a new fire door and frame so it can hold back fire and smoke. The door, frame, seals and hardware all work as one set.
A fire door is only as good as its fitting. The best door in the world will fail if the gaps are wrong or the frame is loose.
Every fire door was tested in a lab with set gaps, hinges and seals. That test sets the rules for how it must be fitted.
Our fitters follow those rules to the letter. We match the hardware, the seals and the frame fixings to the maker’s instructions.
Landlords, agents and building owners fit new doors after a failed fire door inspection, a refit or a change of use. New flats and HMOs also need them.
If you are not sure which doors need replacing, our fire door specialist team can carry out a fire door survey first.
Fitted properly
A good fit is in the detail. These are the points our fire door installers check on every opening before they sign it off.
The frame is fixed and packed to the wall at set points.
Any gap around the frame is filled with fire-rated sealant.
Fire-rated hinges with every screw in place.
A closer sized to the door, tested to EN 1154.
Gaps of 2 to 4 mm on the top and sides.
Locks, latches and handles that match the test evidence.

You get more than a new door. Every installation comes with the paperwork you need to prove it was done right.
Avoid these
We are often called in to put right doors that were fitted badly. These are the mistakes we see most.
Cutting a door beyond the limits in its test evidence voids it.
Standard hinges can melt in a fire. Fire doors need rated ones.
An open gap behind the frame lets smoke straight past the door.
A closer that cannot shut the door against air pressure fails.
A lock or letter plate that is not fire rated weakens the door.
Hanging a new fire door in an old frame is not a tested set.

Most fire door installations are priced per doorset, supplied and fitted. The rating, glass, finish and hardware make the biggest difference.

Answers to what people search for before booking fire door fitters.
A supplied and fitted FD30 internal doorset usually costs £550–£950 before VAT. FD60 doorsets are around £800–£1,300, and flat entrance doorsets £1,100–£1,900. Glass, finish and hardware change the price. Prices include fitting, seals and hinges, and removal of the old door. London rates are usually a little higher than the UK average because of labour and access costs.
The law does not say who must fit them, but the door must perform as tested. In practice that means a competent fitter who follows the test evidence and BS 8214. Poor fitting is one of the main reasons fire doors fail.
Most single doorsets take around a day, including removing the old door. Larger jobs are planned floor by floor so the building stays in use. Odd-sized openings may need made-to-measure fire doors, which take longer to make. Fitting time depends on the wall and frame. Openings that need building work or making good can take longer, and we tell you this when we measure.
Only if the frame is part of the same tested set and in good condition. In most cases a complete doorset, with a new frame, is the safer choice. Old frames are often too damaged, the wrong depth or not part of the door’s test evidence. Fitting a new door into them can mean the door will not perform as tested.
FD30 doors resist fire for 30 minutes and FD60 doors for 60 minutes in a standard test. An "S", as in FD30S, means the door also has smoke seals. Your fire risk assessment says which you need. Read more in FD30 vs FD30S vs FD60 fire doors explained.
A fire doorset is a door, frame, seals and hardware supplied together as one tested unit. It is easier to prove than a door and frame bought separately. Doorsets come from the factory ready to fit, often with the hinges and seals already in place. That makes the fitting quicker and the paperwork simpler.
Most fire doors need three fire-rated hinges, as set out in their test evidence. Using only two, or ordinary hinges, can stop the door performing in a fire. Each hinge should be CE or UKCA marked to EN 1935, with every screw in place. Missing screws are one of the most common faults found in inspections.
You get a fitting record, photos and the maker’s label on each door. Our fire door certification service explains the paperwork in more detail. The record shows the door’s rating, location and the checks we made after fitting. Keep it with your fire safety records, as inspectors and insurers often ask for it.
