Steel fire doors for Kent buildings
For steel fire doors anywhere in Kent, one team handles the survey, supply, installation and handover, covering Maidstone, Gillingham, Chatham and the rest of the county.
For steel fire doors in Kent we order factory-prepared doorsets so the hardware matches the test evidence exactly. Plant rooms, bin stores and warehouses in and around Kent often call for steel doorsets that can take knocks and damp.
Wherever your building is in Kent, the fire safety duties come from national rules, and our installation standard is the same.
How installation differs from timber
Steel frames are fixed with the anchors and fixing centres the manufacturer specifies, and frames are often grouted or packed according to the instructions. Steel doors usually arrive with hinges and hardware preparations made in the factory, so the hardware set must be ordered correctly at the outset. BS 8214:2026 now covers steel, metal and composite doors as well as timber, including how to seal them to the surrounding structure.
What the rules say for Kent
Fire doors in Kent 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 Kent 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 steel fire doors across Kent?
Yes. We cover all of Kent, including Maidstone and Gillingham. Surveys and written quotes are free.
Can steel fire doors be painted?
They are usually supplied powder coated. Repainting on site is possible but must avoid covering seals and labels, and should follow the manufacturer's guidance.
Do steel fire doors need intumescent seals?
Some steel doorsets use intumescent seals and some do not, depending on how they were tested. The certification sets out exactly what is required.
