Fire door work in Hertfordshire spans housing providers with large estates, individual landlords, businesses and homeowners. We price every job from a survey, never from a list price alone, because the condition of the frames and the hardware makes a real difference.
What to check before you buy
Composite doors vary widely. The certification must cover the whole doorset as supplied: the core, skin, frame, glazing, letterplate, viewer and every item of hardware. Ask to see the certificate and the installation instructions, and check that the door's configuration, such as a side panel or glazed panel, is actually covered. BS 8214:2026 now includes maintenance guidance for composite and metal doors, reflecting how common they have become.
Which fire door rules apply in 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 composite fire doors across Hertfordshire?
Yes. We cover all of Hertfordshire, including Watford and Hemel Hempstead. Surveys and written quotes are free.
Can I add a letterbox to a composite fire door?
Only if the letterplate is part of the certified doorset. Cutting one in afterwards would compromise the door's fire performance.
Are composite fire doors as good as timber ones?
Both can perform well when they are certified and installed correctly. Composite doors offer low maintenance and colour choice; timber doorsets offer more flexibility on sizes and finishes. The certification and installation matter more than the material.
