How Much Does a Fire Door Cost to Fit in Croydon?

What you are actually paying for

A fire door is a tested assembly, not just a heavy door. An FD30 door is rated to hold back fire for 30 minutes, but only when it is fitted with the right frame, intumescent strips, fire-rated hinges, a suitable latch and, where required, a self-closer. If one of those parts is missing or badly fitted, the rating no longer counts for much.

This is why the cost of the door leaf is often less than half the job. Much of the price goes on labour and on getting the gaps right. The gap around the edges should usually be about 2 to 4mm, and many older Croydon properties have frames that are out of square or worn, which makes that hard to achieve.

Typical price ranges around Croydon

These are rough guides based on common jobs in the area. Your actual price will depend on the property and the specification, so treat them as a starting point rather than a quote.

• FD30 door leaf hung in an existing, sound frame: roughly £300 to £550 supplied and fitted
• FD30 door with a new frame or lining: roughly £500 to £900
• Certified FD30S doorset, such as a flat entrance door with smoke seals: roughly £900 to £2,000 or more
• Self-closer, fire-rated hinges and signage added to an existing door: roughly £80 to £250
• Glazed fire doors or special finishes: expect to pay more than the figures above

What pushes the price up or down

Two doors that look the same can be priced very differently. These are the most common reasons.

• Frame condition: rotten, damaged or non-standard frames often have to be replaced, which adds time and materials
• Door size: older Victorian and Edwardian houses in areas like Thornton Heath and South Norwood often have odd-sized openings that need a door trimmed or made to size
• Glazing: fire-rated glass and glazing systems cost more than a solid door
• Finish: a primed door you paint yourself is cheaper than a factory-finished veneer
• Number of doors: fitting several doors on one visit usually brings down the cost of each door
• Access and making good: plastering, architrave and decorating around a new frame can add to the bill

Loft conversions, flats and HMOs in Croydon

A lot of fire door work in Croydon comes from loft conversions. When you add a storey to a two-storey house, Building Regulations usually require a protected escape route, which often means fire doors onto the stairway from the habitable rooms. Your building control inspector will check this before signing off the work, so it is worth budgeting for these doors from the start.

In purpose-built blocks and converted houses, flat entrance doors must be fire-rated and self-closing. Under the Fire Safety Regulations 2022, responsible persons in buildings over 11 metres must check flat entrance doors each year and communal fire doors every three months, so faults are often found during these checks. If you let a property as an HMO, Croydon Council's licensing conditions will normally expect fire doors on bedrooms and kitchens, which often means several doors fitted at once.

Getting a quote you can trust

A good quote will name the fire rating, say whether you are getting a certified doorset or a leaf fitted into an existing frame, and list the hardware included. Be careful of very low prices that leave out intumescent strips, smoke seals or a self-closer, because those are exactly the parts that make the door work.

Ask whether the installer will leave you with a record of what was fitted, such as the door's certification label or plug and a list of the components. Landlords and managing agents will need this for their fire risk assessments, and it makes any future inspection much simpler.
