Boiler Service Near Me: Cost, What's Checked & How to Book a Gas Safe Engineer
Searching for a boiler service near you usually means two questions at once: what will it cost locally, and who can I trust to do it safely. This guide covers indicative 2026 prices by boiler type and UK region, exactly what a Gas Safe engineer checks, and why an annual service often costs less when it is bundled inside a boiler cover plan.
Quick answer
A one-off boiler service near you typically costs around £100 in 2026 (roughly £80–£120), though independent local engineers off-peak can charge £70–£95 and national brands £130–£200. Prices run higher in London and the South East and lower in the North and Scotland. Always use a Gas Safe registered engineer and verify their ID card on arrival.
If you want servicing plus breakdown protection, a boiler cover plan at roughly £8–£25 a month often includes an annual service — for some households better value than paying ~£100 for a standalone visit, though it depends on the plan's terms and your boiler's age. This is information only, not financial or gas-safety advice, and we feature a selected panel of providers rather than the whole market.
How to find a boiler service near you
The single most important step is choosing a Gas Safe registered engineer. By law, only a Gas Safe registered engineer may work on gas appliances in the UK — this is the legal replacement for the old CORGI scheme.
Use the official Gas Safe Register postcode search to find registered businesses near you. You can filter by the type of work, so look for "boiler", "domestic" and "natural gas" (or LPG) to match your appliance.
When the engineer arrives, ask to see their Gas Safe ID card. Check the photo, the licence number, the expiry date and the categories of work they are qualified for on the back. Our guide to how to check an engineer on the Gas Safe Register walks through this step by step.

Boiler service cost near me 2026
The average one-off gas boiler service in 2026 is around £100, with most homeowners paying between £80 and £120. Where you land in that range depends heavily on who you book and when.
Independent local engineers are usually cheaper than national brands, especially off-peak in spring and summer. National providers cost more for a one-off visit but can be convenient if you want a recognisable name.
| Who you book | Indicative one-off cost (2026) |
|---|---|
| Independent engineer (off-peak, spring/summer) | from £70–£95 |
| Independent engineer (peak winter) | £90–£130 |
| National brand / large firm (one-off) | £130–£200 |
| Typical UK average | ~£100 |
Prices are indicative and last checked in 2026 — always confirm the figure with the engineer or provider before booking. For a deeper breakdown see our guide to boiler service costs and what's included.
Cost by boiler type
The fuel and appliance type affect how long the job takes and therefore the price. Gas combi boilers are the quickest; oil and LPG appliances tend to cost a little more.
| Boiler type | Indicative service cost (2026) |
|---|---|
| Natural gas (combi or system) | £85–£120 |
| Electric | £70–£110 |
| LPG | £90–£120 |
| Oil | £75–£125 (average around £90–£100) |
Note that oil and LPG work requires an engineer registered for that specific fuel — natural gas registration alone is not enough. Oil-fired appliances are covered by OFTEC registration rather than the Gas Safe Register.
Boiler service cost by UK region
This is the part most cost guides skip when they quote a single national average. The "near me" in your search matters, because labour rates vary noticeably across the UK.
| Region | Indicative gas service cost (2026) |
|---|---|
| London & South East | £100–£130 (often +10–20%) |
| Midlands | £85–£110 |
| North of England | £80–£105 |
| Wales | £80–£105 |
| Scotland | £75–£100 |
Out-of-hours or emergency call-outs sit well above these figures — typically £150–£350 depending on the time and urgency. If you ever smell gas or suspect carbon monoxide, leave the property and call the National Gas Emergency line on 0800 111 999 immediately.
What's checked in a boiler service
A proper service is far more than a quick visual glance. A thorough Gas Safe service typically covers the following eight areas:
- Flue inspection — internal and external checks for sound seals and safe termination.
- Flue gas / combustion analysis — an electronic analyser reads CO, CO2 and the CO/CO2 ratio to confirm the boiler is burning fuel safely and efficiently.
- Burner, heat exchanger and main injector — inspected and cleaned where needed.
- Seals and gaskets — checked for integrity and wear.
- Gas pressure readings — both operating and standing pressure measured against the manufacturer's specification.
- Flame picture / flame sensing — checking the flame is correct and stable.
- Controls and safety devices — pressure-relief valve (PRV), thermostat and safety cut-offs tested.
- Test-fire and visual leak/corrosion check — casing, pipework, expansion vessel and condensate trap inspected, then the boiler is fired up to confirm safe operation.
The visit should end with a written service report and an entry in the boiler's gas log or Benchmark book. The combustion analysis is the heart of the service — it is the main check that protects you from carbon monoxide leaking from your boiler. All of this work must be carried out by a Gas Safe registered engineer; it is not safe or legal to attempt it yourself.
How long does a boiler service take?
A healthy modern combi boiler usually takes 30–45 minutes. An older unit, or an oil boiler, can take up to 1.5 hours because more components need cleaning and adjustment.
If an engineer is in and out in ten minutes without using a flue gas analyser, that may be a sign of a less thorough service — it is reasonable to ask what checks were carried out.
How often should you service your boiler?
For homeowners, an annual service is widely recommended as best practice but is not a legal requirement. It helps keep the boiler safe and efficient and is usually a condition of keeping a manufacturer's warranty valid.
For landlords the picture is different — annual gas safety is a legal duty. Under the Gas Safety (Installation and Use) Regulations 1998, a Gas Safe registered engineer must carry out a gas safety check on relevant gas appliances and flues every 12 months, and the landlord must give the tenant a copy of the record within 28 days (and to new tenants before they move in).
Landlords: the annual gas safety check is mandatory and failing to comply can carry significant penalties. See our guide to Gas Safety Certificate (CP12) cost for landlords for the detail.
Is a service the same as a Gas Safety Certificate (CP12)?
No — and this is one of the most common points of confusion. They are two different things, even though an engineer can often do both in one visit.
- A boiler service is a maintenance and efficiency check: cleaning, combustion analysis, pressure readings and a full performance inspection of one appliance.
- A Gas Safety Certificate (CP12), properly called a Landlord Gas Safety Record, is a legal safety document for landlords confirming the gas appliances and flues in a property have been checked. It is a safety check, not a clean or tune-up.
A standalone CP12 typically costs around £60–£90 for a single appliance, with a little more per extra appliance. A CP12 does not necessarily include the cleaning and efficiency work of a service, so for a let property landlords often arrange both — combining them in one visit usually saves £20–£40 versus booking separately. Read more on CP12 costs here.
What happens if you don't service it?
Skipping services rarely saves money in the long run. The risks stack up:
- Warranty void. Most manufacturer warranties (Worcester Bosch, Vaillant, Baxi, Ideal) require a documented annual service. Miss one and the cover can be invalidated — check your own warranty terms, and see why a documented annual service protects your warranty.
- Higher running costs. The Energy Saving Trust notes that a poorly maintained, inefficient boiler can cost noticeably more to run. Our guide on keeping your boiler efficient explains how to claw that back.
- Carbon monoxide risk. An unserviced boiler is more likely to develop a fault that lets carbon monoxide escape — the combustion analysis in a service exists precisely to catch this. Fit an audible CO alarm regardless.
- Shorter lifespan. A well-maintained boiler can last around 15 years; a neglected one may fail sooner.
The alternative: boiler cover that includes an annual service
Here is the angle the trade-quote sites tend to miss. If you pay roughly £100 a year for a one-off service alone, you get only the service. Many boiler cover plans at £8–£25 a month bundle an annual service plus breakdown repair cover.
Run the maths: a plan at around £10–£15 a month is £120–£180 a year — comparable to, or only a little above, a standalone service — but you also get repair cover if the boiler breaks down. For some households that is better overall value than paying for the service in isolation; for others a one-off service is cheaper. The right choice depends on the plan's terms, excess and your boiler's age, so always read the policy.
| One-off service only | Cover plan with service included | |
|---|---|---|
| Typical cost | ~£100/year | £8–£25/month (~£96–£300/year) |
| Annual service | Yes | Yes (where the plan includes one) |
| Breakdown repairs | No — pay per repair | Yes (per plan terms) |
| Parts & labour on faults | Charged separately | Usually included (check exclusions/excess) |

How we present providers: we feature a selected panel of providers, not the whole market, and may earn a commission if you take out a plan. This does not affect the price you pay. FCA-regulated boiler insurance and unregulated service or care plans are different products — we label which is which, and a service plan is never described as insurance.

How to book and what to have ready
Booking is smoother if you have a few details to hand before you call or fill in the form:
- Your boiler make and model (on the front or a label inside the casing).
- The log book or Benchmark book, if you have one.
- The date of the last service.
- Clear access to the boiler and any external flue.
Book in spring or summer if you can. Demand and prices climb in autumn and winter when boilers fail in the cold, so off-peak booking is usually cheaper and easier to schedule.
How much does a boiler service cost near me in 2026?
Expect around £100 on average for a one-off gas service (roughly £80–£120). Independent engineers off-peak can charge £70–£95, while national brands often charge £130–£200. London and the South East run higher; the North and Scotland tend to be lower. Prices are indicative — confirm with the engineer before booking.
How long does a boiler service take?
A healthy modern combi boiler usually takes 30–45 minutes. Older boilers and oil-fired units can take up to about 1.5 hours because more components need cleaning and checking.
Can I service my own boiler — is DIY legal?
No. Only a Gas Safe registered engineer may legally work on gas appliances in the UK. Gas, burner, flue, sealed circuit, gas valve, PCB and pressure-relief valve work must be left to a Gas Safe engineer — never attempt it yourself. If you smell gas or suspect carbon monoxide, leave the property and call 0800 111 999.
Can I skip a boiler service if it seems fine?
As a homeowner you can — it is not a legal requirement — but it is rarely wise. Skipping services can void a manufacturer warranty, raise running costs, increase carbon monoxide risk and shorten the boiler's lifespan. Landlords have no choice: an annual gas safety check is a legal duty.
Is a boiler service the same as a Gas Safety Certificate (CP12)?
No. A service is a maintenance and efficiency check on one appliance. A CP12 (Landlord Gas Safety Record) is a legal safety document for landlords covering the gas appliances and flues in a property, costing around £60–£90 for a single appliance as a standalone. An engineer can often do both in one visit, but they are different things.
Is it cheaper to get a service or take out boiler cover?
If you only want a service, a one-off visit at ~£100 is the simplest option. A cover plan at £8–£25 a month often includes an annual service plus breakdown repair cover, which can be better overall value for some households — but it depends on the plan terms, excess and your boiler's age.
