Certified fire doorsets for Hertfordshire buildings
Whether your building is in Watford, Hemel Hempstead or a smaller place in Hertfordshire, we can provide certified fire doorsets with the same evidence-led approach.
Every doorset we fit in Hertfordshire 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 Hertfordshire, with less cutting and fewer return visits.
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.
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.
What the rules say for Hertfordshire
The rules that apply to fire doors in Hertfordshire are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts.
Where a Hertfordshire block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.

Common questions
Do you provide certified fire doorsets across Hertfordshire?
Yes. We cover all of Hertfordshire, including Watford and Hemel Hempstead. Surveys and written quotes are free.
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.
How long do doorsets take to arrive?
Lead times depend on the manufacturer, size, finish and ironmongery. Standard sizes can be quick; bespoke sizes and finishes take longer. We give you the lead time with the quote and confirm it at order.
