Bespoke fire doors for any opening
We supply and fit made-to-measure fire doors in London for openings a standard door will not fit. Each bespoke door is built to size, then fitted and certified as a tested set.
Bespoke fire doors explained
A made-to-measure fire door is built for one opening. The maker sizes the door and frame to your measurements, instead of cutting down a stock door.
You may also hear them called bespoke or custom fire doors. They are still tested and certified like any other fire door.
Every fire door has limits on how much it can be trimmed. Cut past them and the door may no longer match its test evidence.
Odd sizes, tall openings and uneven walls are common in London’s older buildings. A bespoke door avoids the problem altogether, and is fitted by the same team that handles our fire door installation.
Owners of period houses, listed buildings and conversions. Also anyone with unusual openings, such as wide double doors or arched heads.
They also suit buildings where every door must match, such as hotels and smart offices.

What people ask about bespoke and custom fire doors.
A bespoke FD30 doorset usually costs £900–£1,800 fitted, before VAT. FD60 doors are around £1,200–£2,400. Period panels and special glass add £250–£700 per door. Bespoke doors cost more than standard doorsets because each is built for one opening. For odd sizes, they are often the only safe option.
Yes. Many makers build fire doors to your sizes, as long as they stay within the range of sizes their test evidence covers. Bespoke doors suit tall, wide, arched or out-of-square openings. They avoid the risk of cutting a stock door beyond what its test allows.
Yes, when they are made within the maker’s tested range and fitted correctly. We check this before ordering. Each door comes with the maker’s label and a fitting record, as part of our fire door certification. That gives you the same proof as a standard certified doorset.
It depends on the door. Most makers allow only a few millimetres per edge. Trimming beyond the limit can void the rating, which is why odd openings need bespoke doors. Always check the maker’s data before trimming. If an opening needs more than the allowed trim, a made-to-measure door is the safe choice. If it is a standard size, a regular fire door replacement is quicker.
Making usually takes a few weeks after you approve the design. Fitting is then usually a day per door. Ordering early avoids leaving openings waiting for doors. If a door is urgent, a temporary certified door can sometimes be fitted while the bespoke one is made.
Yes. Listed buildings may need consent before doors change, so check with your council first. We can supply drawings to help. Many listed buildings can take fire doors that look like the originals. Matching panels, mouldings and finishes helps when seeking consent.
Yes, as long as the glass is fire rated and fitted with the right beads and seals. The glass must be covered by the door’s test evidence. Fire glass carries an etched mark in one corner showing its type. Ordinary glass in a fire door is a common reason for a failed inspection.
In most cases, yes. We can match panels, mouldings, veneers and paint finishes. We bring samples so you can compare finishes on site. For period buildings, we can copy panel layouts and mouldings from your original doors.
