Getting steel fire doors right in Hertfordshire
Across Hertfordshire, from Watford to Hemel Hempstead, we survey, supply and fit steel fire doors for homes, blocks of flats and workplaces.
Plant rooms, bin stores and warehouses in and around Hertfordshire often call for steel doorsets that can take knocks and damp. For steel fire doors in Hertfordshire we order factory-prepared doorsets so the hardware matches the test evidence exactly.
Hertfordshire has a mix of buildings, from purpose-built blocks to converted houses and commercial premises. We tailor the programme to the building, not the other way round.
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 Hertfordshire
In Hertfordshire, 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.
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 Hertfordshire 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.
