FD90 and FD120 fire doors in Hertfordshire: how we work
Throughout Hertfordshire, including Watford, Hemel Hempstead and Stevenage, we survey, quote and fit FD90 and FD120 steel doorsets for plant and high-risk rooms as complete certified doorsets, with the manufacturer's certificate reference on every quote.
What the law says in Hertfordshire
In Hertfordshire, as across England, Approved Document B governs new work and the Fire Safety Order 2005 governs existing premises. Note that Approved Document B is removing the BS 476 fire-resistance test references on 2 September 2029, so specifications are moving to EN classifications such as E30 Sa.
What do FD90 and FD120 fire doors cost in Hertfordshire?
Budget around £1,900 to £3,800 per single doorset for FD90 and FD120 fire doors supplied and fitted in Hertfordshire, excluding VAT. We price each opening separately so nothing is hidden in a lump sum.
We show each door's price separately, so if budget is tight you can phase the work and start with the doors your fire risk assessment prioritises.
