Factors affecting cost in the UK
- ·Region — London and the South East run 15–30% above national averages.
- ·Specification tier — premium materials and finishes can double the base cost.
- ·Access and site conditions — flats, restricted parking and listed buildings add time.
- ·Scope changes mid-project — late design decisions are the biggest cost overrun driver.
- ·Trade availability — quotes rise 10–20% in peak spring and summer months.
Ways to reduce cost
- ·Choose certified FD30 doorsets (door + frame + ironmongery as one kit) rather than building up component-by-component.
- ·Specify factory-finished doors to skip on-site painting.
- ·Use a FIRAS-registered fire door installer to ensure certification.
- ·Buy from specialist suppliers (Vicaima, Distinction, Premdor) via trade rather than retail.
- ·Combine multiple door replacements into one install visit.
Frequently asked questions
- Where are fire doors required in a home?
- In England and Wales, fire doors are required in HMOs (Houses in Multiple Occupation), between a garage and a dwelling, between a loft conversion and the rest of the house (if not compartmentalised differently), and in flats. Building regulations Part B determines specific requirements.
- What does FD30 mean?
- FD30 means the door provides 30 minutes of fire resistance. FD60 provides 60 minutes. The rating refers to the door's ability to prevent the spread of fire and smoke for that period, allowing time for evacuation.
- Can any joiner fit a fire door?
- Fire doors should ideally be installed by a certified installer (e.g. Certifire or BWF-CERTIFIRE scheme registered). An incorrectly fitted fire door — with wrong intumescent strips, wrong gap sizes, or non-fire-rated ironmongery — can fail to provide its rated protection.
