Double fire doors in Hertfordshire: how we work
We supply and fit double fire doors across Hertfordshire, including Watford, Hemel Hempstead and Stevenage. Every job starts with a free measure survey and ends with a handover pack listing each certified doorset fitted.
What the law says in Hertfordshire
Because Hertfordshire is in England, the starting point is Approved Document B for the specification and the Fire Safety Order 2005 for ongoing duties. Blocks with a storey above 11 metres also fall under regulation 10 of the Fire Safety (England) Regulations 2022: communal fire doors checked at least every three months, flat front doors at least every year.
Cost of double fire doors in Hertfordshire
Our guide price for double fire doors in Hertfordshire is £1,600 to £3,400 per pair including fitting, ex VAT. Non-standard sizes, veneers, vision panels and access control push towards the top of the range.
Made-to-measure sizes for older openings, vision panels and upgraded hardware are the usual reasons a door sits towards the top of the range.

Your questions answered
Can you work around tenants or staff?
Yes. We phase work in occupied buildings and keep escape routes available. Each door is planned to be removed and replaced the same day; if that isn't possible, the opening is made secure and we tell you in advance.
Can you fit just one door?
Yes — from a single door to a full building.
Will I get certificates for the doors fitted?
Every doorset is listed in your handover pack with the manufacturer's certificate reference, plus an installation record and photos.
Do pairs cost much more than singles?
Roughly 1.7 to 2 times a single doorset, depending on hardware.
