Getting certified fire doorsets right in Greater London
Our certified fire doorsets service runs throughout Greater London. Main towns include London, Islington and City of Westminster, and we cover the smaller places in between.
Every doorset we fit in Greater London is handed over with its certificate reference and photographs of the frame fixing and gap sealing. Pre-hung doorsets keep disruption down in occupied buildings in Greater London, with less cutting and fewer return visits.
Fire door work in Greater London spans housing providers with large estates, individual landlords, businesses and homeowners. We price every job from a survey, never from a list price alone, because the condition of the frames and the hardware makes a real difference.
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.
Which fire door rules apply in Greater London?
In Greater London, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet. In London, the London Fire Brigade is the enforcing authority for fire safety law.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Greater London building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.

Common questions
Do you provide certified fire doorsets across Greater London?
Yes. We cover all of Greater London, including London and Islington. Surveys and written quotes are free.
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.
Do doorsets come painted?
They can be supplied primed, factory painted, veneered, laminated or with a composite skin, depending on the product. Factory finishes avoid painting over seals and labels on site.
