Certified fire doorsets: our service in East Sussex
We provide certified fire doorsets across East Sussex, covering 10 towns and 34 postcode districts, including Brighton, Eastbourne and Hastings.
Pre-hung doorsets keep disruption down in occupied buildings in East Sussex, with less cutting and fewer return visits. Every doorset we fit in East Sussex is handed over with its certificate reference and photographs of the frame fixing and gap sealing.
Wherever your building is in East Sussex, the fire safety duties come from national rules, and our installation standard is the same.
Why choose a doorset over a door leaf?
A fire door's rating belongs to the assembly that was tested, not to the leaf on its own. When a certified leaf is hung in an old frame with mismatched hinges and seals, nobody can say with confidence how it will perform. A doorset arrives with the frame, gaps and ironmongery already matched, so the installer's job is to fix it correctly into the opening and seal it to the structure.
Doorsets also cut time on site, which matters in occupied buildings: less cutting, less dust and fewer return visits.
Which fire door rules apply in East Sussex?
Fire doors in East Sussex fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.
For residential buildings in East Sussex above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Common questions
Do you provide certified fire doorsets across East Sussex?
Yes. We cover all of East Sussex, including Brighton and Eastbourne. 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.
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.
