Certified fire doorsets: our service in Northamptonshire
Whether your building is in Northampton, Corby or a smaller place in Northamptonshire, we can provide certified fire doorsets with the same evidence-led approach.
Doorsets suit refurbishment programmes in Northamptonshire, where several openings can be measured, ordered and fitted in one planned sequence. Pre-hung doorsets keep disruption down in occupied buildings in Northamptonshire, with less cutting and fewer return visits.
Managing agents, landlords, schools, care providers, businesses and homeowners in Northamptonshire can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
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 Northamptonshire?
England's framework applies in Northamptonshire. 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.
For blocks over 11 metres in Northamptonshire, 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.

Common questions
Do you provide certified fire doorsets across Northamptonshire?
Yes. We cover all of Northamptonshire, including Northampton and Corby. 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.
