How Much Does a Fire Door Cost in the UK?

Fire door pricing varies a lot more than most guides let on — a domestic-style FD30 and a heavy steel fire exit door for a warehouse aren't remotely the same job. Here's a realistic breakdown of what you should expect to pay in the UK in 2026, and what actually moves the price.

Average Fire Door Costs at a Glance

These figures are for a standard supply-and-fit job by a certified installer, and assume a fairly typical single-door opening:

Labour typically makes up 30–50% of the total, with certified installers charging in the region of £250–£400 per day. All of the above is exclusive of the standard 20% VAT that applies to commercial installations.

What Drives the Price Up or Down

• Fire rating. FD60 doors need thicker cores and more robust intumescent seals than FD30, so they cost more to manufacture and fit.
• Material. Timber, composite and steel all sit in different price brackets — steel is the most expensive but the most durable for high-traffic commercial and industrial use.
• Glazing. Any vision panel needs fire-rated glass and the correct beading, which adds cost over a solid leaf.
• Hardware. Fire-rated hinges, closers, and panic hardware cost more than standard ironmongery, and using anything else invalidates the certification.
• Frame condition. If the existing frame needs replacing rather than reusing, that adds materials and labour on top of the door itself.
• Single vs double doors. Double door sets cost roughly double the leaf cost, plus extra ironmongery for the meeting stiles.

Hidden Costs Worth Budgeting For

The headline door price rarely covers everything. Before you commit to a budget, factor in:

• Certification and documentation. Proper paperwork proving the installed door meets its rating — essential for your fire risk assessment file.
• Disposal of the old door. Removing and disposing of an existing door and frame is sometimes quoted separately.
• Making good. Redecorating or patching plasterwork around a replaced frame.
• VAT. Always confirm whether a quote is VAT-inclusive before comparing prices.

Steel Fire Exit Doors: A Different Cost Bracket

Warehouses, industrial units and high-traffic commercial premises typically need steel fire exit doors rather than timber — they're built to withstand heavier daily use and, in many cases, exposure to the elements on an external escape route. That durability is reflected in the price, but it also means far less frequent replacement than a timber door under the same traffic. Our steel fire exit door servicing covers installation, repair and the regular servicing that keeps them compliant year after year.

Common Questions

Fire Door Cost FAQs

How much does it cost to fit a fire door in the UK?

A standard FD30 timber fire door supplied and fitted typically costs £400–£700. An FD60 door runs £700–£1,200, and a steel fire door for industrial or commercial use is usually £1,000–£3,500 depending on size and hardware.

Is VAT charged on fire door installation?

Yes — standard 20% VAT applies to commercial fire door supply and installation. Always confirm whether a quote is VAT-inclusive before comparing suppliers.

How much does a fire door inspection cost?

It depends on the number of doors and the size of your building, since most inspectors price per visit rather than per door. Ask for a fixed-price quote based on a walk of your specific premises rather than relying on a generic per-door rate.

Can I install a fire door myself?

Legally you can, but a fire door only performs to its rating if the frame, gaps, seals, hinges and self-closer are all installed correctly. An incorrectly hung door can fail its rating even with a fully certified leaf.

Do I need building control sign-off for a new fire door?

Fire door work typically falls under Building Regulations Part B, and significant changes to fire compartmentation or escape routes may need building control approval. Check with your local authority or fire risk assessor if you're unsure.
