Certified fire doorsets in Croydon: what's involved
Our certified fire doorsets service in Croydon is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Croydon has a broad mix of buildings, including student accommodation, clinics and mixed-use office buildings, and the same fire door principles apply to all of them.
Every doorset we fit in Croydon is handed over with its certificate reference and photographs of the frame fixing and gap sealing. Doorsets suit refurbishment programmes in Croydon, where several openings can be measured, ordered and fitted in one planned sequence.
How is a doorset installed?
The opening is prepared to the size and tolerances in the manufacturer's instructions. The frame is fixed with the specified fixings at the specified centres, packed where needed, and checked for square, plumb and twist. The gap between frame and wall is then sealed with a material covered by the evidence, which BS 8214:2026 now describes in more detail. Finally the leaf is adjusted, the closer is set and the assembly is tested before the architraves go on.
As standard, the work covers:
- Frame fixing and frame-to-wall gap sealing
- Installation to the manufacturer's instructions
- Pre-hung, pre-machined doorsets where available
- Certificate references and photo record per opening
The regulations behind fire doors in Croydon
England's framework applies in Croydon. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors. Enforcement of fire safety law in Croydon sits with the London Fire Brigade.
For blocks over 11 metres in Croydon, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.
Where certified fire doorsets fit in Croydon
You are most likely to need certified fire doorsets if you look after blocks of flats, new-build and conversion projects or refurbishment programmes. Whatever the building in Croydon, we survey each opening and tell you which doors need work and which do not.
The steps on a Croydon installation
- Survey and measure every structural opening
- Specify doorsets by rating, size, hand, finish and hardware
- Prepare openings and remove existing doors and linings
- Fix and seal the frames to the structure
- Hang, adjust and test each leaf and closer
- Fit architraves, make good and hand over evidence
Guide prices in Croydon
If you need a budget figure first, the guide for certified fire doorsets is £650–£1,300 for an FD30 doorset and £850–£1,800 for FD60, supplied and fitted, ex VAT. We firm that up after a survey, pricing each door separately so you can see where the money goes.

Questions
Do you cover CR7 and nearby postcodes?
Yes. We cover Croydon including CR7, and nearby towns such as South Croydon and Wallington. The survey and written quote are free.
How quickly can you survey in Croydon?
It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
Can a doorset be fitted into an existing opening?
Usually, yes. Doorsets are made to fit the structural opening once the old frame is removed. We measure the opening on the survey so the doorset is made to the right size and the gaps to the wall stay within what the evidence allows.
Are doorsets more expensive than a leaf?
The product costs more, but the labour is often lower and the result is better evidenced. Where a frame would need replacing anyway, a doorset is usually the better value.
