These prices cover the cost of the service itself. If your engineer finds a fault during the visit, any repairs or replacement parts are usually quoted separately.
Boiler services are typically quoted as a fixed cost job. If anything more than a minor repair is required, then this should be quoted and agreed separately.
What Impacts the Cost of a Boiler Service
Annual boiler service quotes will mainly depend on the type of boiler you have, whether you're using a local tradesman, and where you're located in the UK.
- Location — Labour rates are typically £10 to £20 higher in London and the surrounding areas than the UK average.
- Boiler type — The fuel your boiler uses is one of the biggest factors in the price, since some systems need extra safety checks.
- Boiler condition — Older or poorly maintained boilers can take longer to clean and adjust.
- Access — A boiler that's harder to reach adds to the time an engineer needs, and therefore the cost.
- Local engineer vs. national company — National companies often charge more to cover higher overheads.
As your location and type of boiler are probably the biggest factors impacting boiler service prices, it makes sense to break down how these affect costs in more detail.
Annual Service Costs by Boiler Type
Some boiler systems may need more time and additional safety checks during a service, so the type of boiler you have can be one of the biggest factors in determining your service costs.
| Service Type | Duration | Average Cost |
|---|---|---|
| Annual Gas Boiler Service Price | 1 to 1.5 hours | £85–£120 |
| Annual Electric Boiler Service Price | 1.5 to 2 hours | £75–£110 |
| Annual LPG Boiler Service Price | 1.5 to 2 hours | £90–£120 |
| Annual Oil Boiler Service Price | 1.5 to 2 hours | £90–£125 |
| Annual Biomass Boiler Service Price | 3 to 4 hours | £180–£350 |

Gas Boiler Service Cost
Gas-fuelled boilers are the most common type of boiler in UK homes, which means they are typically straightforward and relatively affordable to service. The typical cost to service a gas boiler is between £85 and £120.
Electric Boiler Service Cost
With no combustion process and all the associated components, electric boilers are probably the simplest to service, which is reflected in the cost. Servicing costs for an electric boiler should be between £75 and £110.
LPG Boiler Service Cost
With their stored fuel systems, LPG-fuelled boilers require additional safety checks, which naturally take more time. This means the typical cost to service an LPG boiler is between £90 and £120.
Oil Boiler Service Cost
An oil-fuelled boiler usually requires more in-depth cleaning and maintenance during a service, which increases the cost. Servicing an oil boiler should cost between £90 and £125.
Biomass Boiler Service Cost
Biomass boilers need more involved servicing than a standard gas boiler, as the process includes flue gas analysis alongside cleaning and safety checks. A biomass boiler service typically costs between £180 and £350.
Is servicing a biomass boiler more involved than a gas boiler service?
"An annual biomass boiler service typically costs £180–£350. It is more thorough than a gas boiler service due to the additional cleaning and maintenance required."
Boiler Service Price Variation Across the UK
As supply costs for this type of job are low (typically around £5), boiler service quotes you get are mostly going to be for the labour cost of servicing the boiler.
Because labour costs typically vary across the UK, this means that the cost of your boiler service can be lower or higher than the UK average, depending on where you live.
The table below shows how the average boiler service costs vary by region.
| Region | Typical Cost | Average vs UK |
|---|---|---|
| London and South East | £100–£120 | +10% |
| Midlands | £85–£110 | 0% |
| North England | £80–£105 | -10% |
| Scotland | £75–£100 | -15% |
| Wales | £80–£105 | -10% |

Additional Boiler Service Costs
A boiler service is usually a fixed-cost job, but your engineer may recommend some follow-on work if they spot an issue during the visit. Common additional costs include:
- Radiator bleeding — Releases trapped air so radiators heat evenly and don't waste energy. Costs around £100.
- System power flush — Clears sludge and debris from an old or inefficient heating system. Costs around £400.
- Smart thermostat installation — Gives you more control over your heating schedule and can help lower energy bills. Costs around £265.
- New radiators — Worth considering if bleeding and flushing haven't improved performance. Costs around £200 per radiator.
These aren't part of a standard service. Your engineer should always quote separately for any extra work before carrying it out.
What Type of Tradesperson Do I Need for My Boiler Service?
The type of tradesperson that you need to hire to service your boiler depends on the type of system you have:
- Gas Boiler Service — It's a legal requirement to have a Gas Safe registered engineer carry out any work.
- LPG Boiler Service — A Gas Safe registered engineer, but with an additional LPG qualification.
- Oil Boiler Service — Requires an OFTEC-registered technician for installation and any maintenance tasks.
- Electric Boiler Service — Should be serviced by a heating engineer or a qualified electrician with boiler experience.
What Does a Boiler Service Quote Include?
Not sure what to expect during your boiler service appointment?
It's best to think of a boiler service as a diagnostic health check. You'll find out what's right and wrong with your boiler, but you won't get repairs made on the spot (unless it's a clear safety hazard).
Broadly, this includes:
- Manually inspecting the boiler, pipework, fittings, and flue for leaks.
- Testing the boiler is working correctly, including controls and temperature settings.
- Checking the boiler for mechanical or electrical faults.
- Issuing a safety report to confirm the boiler is in working order.
- Advising on any work or potential issues that may require further action.
For clarity, here's what's not included in a typical boiler service quotation:
- Major boiler repairs, and the supply of required replacement parts
- Power flushing
- Magnetic filter cleaning
- Boiler replacements
If you're unsure of what's being checked, ask for written confirmation at the time of requesting a quote.
What's Involved in a Boiler Service?
In the UK, you are not permitted to legally carry out a boiler service yourself, unless you are qualified to do so. This is not something you can do as a DIY job, due to both the legal and safety requirements involved.
To have your boiler serviced by a professional, you can hire a heating engineer via MyJobQuote. To ensure you get the best price, it's always recommended to get three separate quotes first (free, no obligation to commit).
Once you have booked your boiler service, below is a guide to what you can expect to happen during the process:
Before the Service
- Visual Inspection — The engineer will carry out a visual inspection of the boiler to ensure it appears to be in full working order. This is done according to current standards to look for leaks or corrosion. They will also visually check the flame in your boiler.
During the Service
- Boiler Casing Removal — Removing the boiler casing, the engineer will then check internal components to ensure everything is working correctly. They will clean the inside of the boiler, including the burner, spark probe, main injector, and heat exchanger.
- Flue, Gas Pressure, and Flow Check — The flue will be inspected to ensure there are no obstructions inside the terminals and that it's fitted correctly and safely. The engineer will also test to ensure the boiler has the correct gas pressure and flow, in line with the manufacturer's guidelines.
- Safety Checks — All safety devices that shut down the boiler in the event of a fault will be tested to ensure they are working correctly.
After the Service
- Final Checks — Once all the above points have been completed and any action taken, the boiler will be fired up to check for any faults while it is in operation.
Checklist: Hiring a Heating Engineer to Service a Boiler in the UK
When you get your boiler serviced, there are a few things to consider when looking for the right tradesman for the job:
- Are they Gas Safe registered? Only engineers listed on the Gas Safe register are legally allowed to work on a gas boiler, while electrical boilers should be serviced by a qualified electrician.
- Does the engineer have the right experience? Make sure the engineer has worked on your type of boiler previously and can provide confirmation that they have the correct qualifications and certifications required.
- Do they have public liability insurance? Although not a legal requirement, it's standard for any tradesmen to have insurance that provides protection in the event of accidental damage or injury while servicing or working on your boiler.
- Have you asked for recommendations or reviews? See if any friends or family use a boiler engineer they would recommend, check for online reviews and read customer feedback on MyJobQuote.
- Have you gathered at least three quotes? Search for boiler specialists using MyJobQuote and ask more than one company for a detailed quote. This will help you compare prices in your area.
- Have you received an itemised breakdown? Ask for a clear, itemised breakdown of the costs, so you can not only ensure you're paying a fair price but won't be hit with any unexpected charges.
- Do they offer any guarantees on their work? When you get your boiler serviced, especially if any additional work is carried out, you should always receive a guarantee or boiler warranty in the event of any issues.
Local Engineer vs National Provider for Boiler Services
When booking your annual boiler service, you have a choice between a local tradesman or a national boiler servicing company.
Here's how the two compare:
| Factor | Local Engineer | National Company |
|---|---|---|
| Availability | Often same-day or next-day | Wider coverage, but a longer wait to book |
| Cost | Lower overheads, usually cheaper | Higher overheads, usually pricier |
| Service | More personalised, often the same engineer each year | Standardised process, recognised brand |
| Parts | Can take longer to source manufacturer-specific parts | Easier access to manufacturer parts |
| Emergency cover | May not offer 24/7 call-out | Often has 24/7 emergency support |

We recommend using a local company to service your boiler to ensure a fast, reliable service, at the best price possible.
What is involved in using a boiler guarantee if it’s worn down before its time?
"For a boiler warranty to be valid, you MUST service the boiler every 12 months. In the absence of this, you will not have any case."
How Do I Know If My Boiler Needs a Service?
If you think something's wrong with your heating, and your annual boiler service isn't due, it can still be a good idea to have someone check if you need any boiler maintenance or repairs.
It's important to note that unresolved issues relating to fuel-burning boilers could lead to a risk of carbon monoxide poisoning, and electrical faults can become a potential fire risk.
If you're experiencing any of the following, it could be a sign that your boiler needs a service:
- Strange Noises Coming from the Boiler — While some running noise is normal, constant banging, knocking, or gurgling sounds aren't normal, and could mean your boiler needs attention.
- Repeated Loss in Water Pressure — It's normal to top up your pressure every now and again, but if it's repeatedly dropping after being topped up, it might mean there's a leak somewhere in your system.
- Lack of Heating — If your heating simply isn't working, your boiler is probably the reason and needs some maintenance.
- Change in Flame Colour — In gas boilers, the flame should be blue. If it's changed to yellow or orange, you need urgent attention from a Gas Safe registered engineer as this could lead to a dangerous situation.
- Error Codes Showing — If your boiler has an error code that you're unable to clear yourself, it's time to call in a local engineer to carry out some regular servicing or boiler repairs.
Why is my boiler making a bubbling or gurgling noise?
"This could be due to scale build up in your boiler."

Ask your question
How Often Should You Service Your Boiler?
You should check with your manufacturer to see the service period of your particular boiler model.
As a general rule of thumb, a boiler should be serviced 12 months after it has been installed, and it should then be serviced every 12 months thereafter.
How can I ensure my boiler is ready for the winter?
"We would recommend getting an annual boiler service once a year and if this hasn't been done for a while, getting a service booked in with a qualified Gas Safe Engineer."
Tips For Saving On Boiler Costs
While monthly payments may be easier to manage financially, keeping your boiler running efficiently doesn't have to be expensive. Below are some tips on how to reduce servicing and boiler repair costs to be cost-effective without compromising on the quality of service you receive.
Check Your Boiler Warranty
Before arranging a boiler service, it's worth checking your warranty and, if applicable, boiler cover plan. Some warranties include an annual service as part of the initial purchase, or may cover the cost of certain repairs, particularly if your boiler is relatively new.
Book Appointments in Advance
Arrange for your boiler to be serviced in advance so you can put the date in the diary and provide yourself time to get the best deal. Booking your appointment during the quieter months, such as off-season (spring and summer), can potentially reduce costs.
Having your boiler regularly serviced can also help avoid last-minute call-outs, as emergency plumbing can automatically increase the cost. The average call-out fee in the UK is around £75, followed by an hourly rate to carry out the work.
Compare Several Quotes
By comparing more than one quote, you can ensure you're getting a fair price. Although it's good to remember that the cheapest isn't always the best option in the long run.
Choose Reputable Engineers
By following our checklist for hiring a qualified heating engineer, you can ensure you're hiring a reputable tradesman. This will help to provide the peace of mind that you're hiring the right person for the job, and you won't be caught out by any additional costs or labour fees.
FAQs
What Are the Benefits of an Annual Boiler Service?
Having your boiler serviced on an annual basis protects your family from dangers such as gas leaks and carbon monoxide, or electrical faults, improving the reliability and lifespan, as well as saving on repairs, improving efficiency and potentially lowering your energy bill. It will also help keep your boiler warranty valid.
Is an Annual Boiler Service a Legal Requirement?
If you're a homeowner, it's best practice to have your boiler serviced regularly, although it's not a legal requirement. However, if you're a landlord in the UK, you're legally required to have your boiler serviced annually under the Landlord and Tenant Act 1985.
How Much Does a Commercial Boiler Service Cost?
For a commercial boiler that's 40kW or under, there is usually a minimum call-out charge of around £95. However, this may vary between tradesmen, and costs are likely to be higher in areas such as London and the South East due to covering higher labour fees.
Can You Get a Boiler Service Grant?
Government-backed schemes typically cover boiler replacements and upgrades for eligible parties, not for routine boiler servicing. It's best to check with your local council to see what's available in your area.
When Is the Best Time to Get a Boiler Service?
It's best to get a boiler service in the summer months, as there's typically a surge in boiler services being booked in the winter months. The best way to beat the annual service check rush is to simply book in advance.
Can I Complete a Boiler Service Myself?
No, you cannot carry out a boiler service as a DIY job. To ensure your safety and compliance with heating regulations, you must hire a qualified engineer suitable for the job.
Do Building Regulations Apply for a Boiler Service?
You don't need Building Regulations approval for a boiler service. However, if your boiler or central heating system needs to be replaced, approval is required due to safety considerations. Under current building regulations (Part L), any new gas condensing boiler must meet a minimum of 92% ErP efficiency.
Are Gas and Electrical Safety Certificates Included With a Boiler Service?
No, gas and electrical safety certificates aren't automatically provided with a standard boiler service, and you don't legally require a copy. However, if you're a UK landlord, legally you must renew a Gas Safety Certificate annually for properties with mains gas. An Electrical Safety Certificate is also required every 5 years.
Does Boiler Cover Include an Annual Service?
Some boiler cover plans include an annual service as standard, though this varies by provider, so it's worth checking your policy documents. Monthly boiler cover typically costs £8 to £13, or £180 to £300 as an annual package, and can also cover the cost of repairs and call-outs.
