Gas Appliance Repair Cost UK 2026
Gas work must be done by a Gas Safe registered engineer — there is no legal DIY route. In Q3 2026 a call-out and diagnosis costs about £60–£120, most boiler repairs land at £120–£450 including parts, and a gas cooker repair is typically £80–£200.
Quick answer: what does it cost?
In Q3 2026, call-out and diagnosis typically costs £60–£120 in the UK. Across every option on this page prices run from £60 to £450. Where you land depends mostly on access, the condition of what is already there, and your region — London and the South East typically add 10–25%.
Gas Appliance Repair Cost UK 2026 — Full Price Table
Typical UK prices for Q3 2026 for gas appliance repairs. Any gas work must legally be carried out by a Gas Safe registered engineer, so always check the engineer’s ID card. What you pay is mostly the call-out plus labour, with parts on top — a thermocouple is a few pounds, a fan or PCB runs into three figures. A one-off repair is cheaper than a service-plus-repair visit, and an out-of-hours call-out costs more than a booked slot.
| Item | Typical cost | Notes |
|---|---|---|
| Call-out and diagnosis | £60–£120 | Often credited against the repair |
| Hourly rate thereafter | £50–£90/hr | Higher in London and out of hours |
| Boiler repair (typical) | £120–£450 | Parts and labour |
| Boiler service | £70–£120 | Annual; keeps the warranty valid |
| Gas cooker / hob repair | £80–£200 | |
| Gas fire service or repair | £70–£250 | Includes flue check |
| Gas safety certificate (CP12) | £60–£120 | Landlords; annual |
| Emergency / out of hours | £120–£250 call-out |

Regional Price Variation
Labour rates are the main regional driver, so the same job can differ by a third across the UK. The table below applies typical regional labour weighting to call-out and diagnosis (£60–£120 at the UK average).
| Region | Typical range | vs UK average |
|---|---|---|
| London | £73–£146 | +22% vs UK average |
| South East | £67–£134 | +12% vs UK average |
| East of England | £63–£126 | +5% vs UK average |
| South West | £61–£122 | +2% vs UK average |
| Midlands | £60–£120 | 0% vs UK average |
| North West | £58–£115 | -4% vs UK average |
| Yorkshire & North East | £56–£113 | -6% vs UK average |
| Wales | £56–£113 | -6% vs UK average |
| Scotland | £58–£115 | -4% vs UK average |
| Northern Ireland | £53–£106 | -12% vs UK average |
Regional weighting is indicative and reflects labour-rate differences, not material costs, which are broadly national.
What’s Included in a Gas Safe Engineer Quote
A complete quote should cover all of the following. If any line is missing, it is not a cheaper quote — it is an incomplete one, and the gap usually reappears as a variation once work has started.
- Attendance by a Gas Safe registered engineer
- Diagnosis and a written explanation of the fault
- Gas tightness and combustion checks
- Parts fitted to manufacturer specification
- Advice on whether repair or replacement is the better value
What Moves the Price Up or Down
Access
Restricted access, upper floors, scaffolding, or no parking near the property all add labour hours before any work happens. This is the most under-estimated cost on almost every quote.
Region
Labour rates vary 20–30% across the UK. Materials are broadly national, so the more labour-heavy the job, the bigger the regional swing.
The fault and the part
Diagnosis is the fixed cost; the part is the variable. A blocked condensate pipe or a faulty thermocouple is cheap; a fan, gas valve, heat exchanger or PCB can cost more than an old appliance is worth. Ask for the part price separately from the labour before you approve the repair.
Existing condition
Preparation and remedial work to what is already there is the most common reason a final bill exceeds the headline rate. A survey before quoting protects both sides.
When you call
An emergency or out-of-hours call-out carries a premium, and no heat in mid-winter is the busiest, dearest time to ring round. A booked weekday slot — or bundling the fix into an annual service — is nearly always cheaper.
Scale
Fixed costs — set-up, access equipment, waste disposal, travel — are spread across the job, so the per-unit rate falls as the job gets bigger.
Five Ways to Bring the Cost Down
- Get three like-for-like quotes. The spread between the highest and lowest quote on the same specified scope is routinely 25–40%. That is the single biggest saving available to you, and it costs nothing.
- Book it, do not emergency it. Unless it is a leak or total loss of heat in a cold snap, a planned weekday visit avoids the out-of-hours premium. Report a smell of gas to the emergency line first — that is a safety call, not a repair.
- Combine the repair with the service. If your annual boiler service is due, having the fault fixed in the same visit means one call-out, not two.
- Know when to stop repairing. On an appliance over 10–12 years old, a major part failure is often the point to replace rather than repair — pouring money into an obsolete boiler is the classic false economy.
- Describe the fault clearly. Note the make, model, any error code and exactly what it does before you call. The engineer can then bring the likely part first time, saving a return visit you would otherwise pay for.
How to Choose the Right Gas Safe Engineer
Price is the easiest thing to compare and the least useful on its own. Before you accept a quote, check:
- Public liability insurance — ask for the certificate, not just a claim that they have it, and check it is in date.
- Relevant registration or accreditation for the trade, where one exists, and that it covers the specific work you need.
- Recent, verifiable work — ask for two addresses from the last six months, and follow them up.
- A written, itemised quote with scope, materials, timescale, payment stages and what is excluded.
- A workmanship guarantee in writing, and clarity on who honours it if the firm ceases trading.
The Law on Who Can Work on Gas
Gas is the one home repair where using the wrong person is not just risky but illegal. Before any work on a boiler, cooker, fire or flue, know the rules:
- Gas Safe registration is a legal requirement. Only an engineer on the Gas Safe Register may work on gas appliances in the UK. Ask to see the card and check the licence number covers the appliance type.
- Landlords must hold a current Gas Safety Record. Every gas appliance in a rented home needs an annual check by a registered engineer.
- Warning signs mean stop. A lazy yellow flame, sooting around an appliance, excess condensation or a smell of gas all point to incomplete combustion. Turn it off and call an engineer.
Never let an unregistered handyman touch a gas appliance to save money — carbon monoxide is odourless, and the saving is trivial against the risk. If you let property, see our landlord safety certificate cost guide for the full schedule of checks.
Gas Appliance Repair Cost UK 2026 — FAQs
A common rule of thumb: if the repair costs more than about a third of a new boiler and the unit is over 10 years old, replacement usually wins on total cost. Under 8 years old with a repair below £400, repairing almost always makes sense.
Ask for their Gas Safe ID card and check the licence number on the official Gas Safe Register — the card shows which appliance types they are qualified for, and being registered for boilers does not automatically cover fires or cookers.
Do not use switches or naked flames, open doors and windows, turn off the supply at the meter if you can reach it safely, leave the property and call the National Gas Emergency Service on 0800 111 999. That call is free and available 24 hours.
For most manufacturer warranties it is a condition — miss one and the cover can lapse, which is an expensive way to save £90. It also catches the small faults that turn into January breakdowns.
Three is the sweet spot. One gives you no benchmark, two leaves you guessing when they disagree, and beyond three you are usually just delaying the job. Make sure all three are quoting the same scope — a cheap quote that excludes preparation, disposal or making good is not actually cheaper.
Ranges on this page are what a homeowner typically pays. Sole traders below the VAT registration threshold do not charge VAT; VAT-registered firms add 20%. Certain works — some energy-saving measures, and renovations of properties empty for over two years — can qualify for a reduced rate, so ask if you think you qualify.
Usually three reasons: different scope (what preparation and making good is included), different materials, and how busy the trade is — a firm with a full order book prices high because they do not need the work. Always compare the written scope line by line, not just the total.
