What Does An FD30 Fire Door Cost In London In 2026?

The honest answer is that FD30 fire door cost in London varies significantly depending on several factors — and most online price guides are either out of date or vague to the point of uselessness. This page gives you the actual cost ranges Doorz London works to in 2026, explains what drives the variation, and tells you what to watch out for when comparing quotes.

What Drives The Price Variation?

1. Whether A New Frame Is Required

This is the single biggest variable. If the existing door frame is fire-rated, square and in good condition, the door leaf can be replaced without disturbing the frame — significantly lower cost. If the frame is non-rated, warped, worn or damaged, a new fire-rated lining must be installed. Doorz assesses this at the survey visit — it is not charged as an extra after the work has started.

2. Standard vs Non-Standard Door Size

Standard UK door sizes (762mm × 1981mm and 838mm × 1981mm) are available off-the-shelf from trade suppliers. Period London properties — Victorian terraces in Islington, Camden or Hackney, Georgian properties in Westminster or Kensington — frequently have non-standard openings. A door that needs to be made to measure costs more and takes longer to source, typically 5–10 working days.

3. Finish

Unfinished (bare wood, to be painted or stained on site) is the cheapest option and common for HMO compliance work. Pre-finished white primed doors cost a little more. Oak veneer or solid oak fire doors cost significantly more — typical for owner-occupier properties in higher-value London boroughs like Richmond or Kensington where the finish needs to match the interior.

4. Quantity

The per-door cost falls as the number of doors increases. A single door replacement and an eight-door HMO package involve the same set-up costs (survey, scheduling, van, equipment) spread across different numbers of units. Doorz applies quantity pricing to all multi-door jobs — we set this out transparently in the quote.

5. Access Difficulty

Ground floor doors in straightforward access — standard cost. Upper floor rooms in houses with narrow stairs, flats in buildings with no lift, properties with difficult parking or access restrictions — these all add time and therefore cost. Doorz flags access considerations at survey and prices accordingly.

FD30 Fire Door Costs By London Borough

Costs do not vary significantly by borough — the price is determined by the job specification, not the postcode. However, some London areas have specific characteristics that affect cost: non-standard door sizes in period properties in Islington, Camden and Kensington; access constraints in tower block properties in Tower Hamlets and Southwark; and above-average specification requirements for high-rise buildings in Westminster and Canary Wharf.
