Boiler Service Cost UK 2025

Why pay for an annual boiler service?

Getting an annual boiler service is one of the best ways to keep your heating system in good shape. It helps you catch problems early, so you do not get any surprises later. A yearly boiler service also makes sure the boiler is safe, works well, and is ready for the winter months.

A yearly check from a Gas Safe engineer or a qualified engineer for oil boilers can help keep you safe from carbon monoxide. This kind of annual servicing can lower the risk of carbon monoxide poisoning. It also helps your boiler last longer. You may not have to pay high boiler repair costs or worry about boiler repair as often. For landlords, having a safe engineer do annual servicing is not just a good practice, but it is also a legal requirement.

What affects the cost of servicing your boiler?

The cost of a boiler service in the UK can go up or down for many reasons.

Where you live, the type of boiler you have, and the company you choose, all change the price you pay for a boiler service. A gas boiler will be less expensive to get serviced than an oil or electric one. A newer boiler can also cost more to get checked. If repairs or new parts are needed in the middle of the boiler service, the price will also go up.

It is smart to get quotes from several companies before you book your boiler service. This way, you and your home get the best deal for what you need.

• The type of boiler you use matters when it comes to service cost. It could be gas, combi, system, conventional, oil, or electric boilers.
• Where you live can change the price a lot. In London and the South East, service cost is higher than what people pay in the North of England, Wales, or Scotland.
• The time of year has an effect on service cost. Prices go up in the winter months since many people want to get their boilers checked.
• The provider you choose will make a big difference. A large company like British Gas will likely be more to pay than hiring a local engineer.
• When there is extra work, you will pay a higher service cost. A standard check-up always costs less than doing repairs, adding new parts, or cleaning the internal components.

Boiler service cost trends: 2023 vs 2024 vs 2025

The price for an annual boiler service is higher now than it was a few years ago. Workers’ pay has gone up, and things cost more because of inflation. Parts and materials for a boiler service are also more costly. Because of this, the cost that people pay for a regular boiler service is now more than before.

Here’s how prices compare year-on-year:

This means that the boiler service costs have gone up by 5–10% since 2023. A lot of people will need to pay an extra £10–£20 each year for the boiler service. The rise is not huge, but it does put more pressure on people. This is on top of higher energy bills.

Booking a boiler service when it is not winter can sometimes help you pay less. You might save money if you book a boiler service plan. If you want to know what you have to pay each month, look at monthly payment plans. Before you choose, make sure to compare boiler cover. This can help you find the best deal for you.

What does a standard boiler service include?

A standard boiler service in 2025 is not just a quick look at the boiler. A qualified engineer will do a careful check. This is to make sure your central heating system is safe and works as it should. The engineer wants your heating system to work well so you get the best out of it.

No matter if you own a gas boiler, a combi boiler, an oil boiler, or an electric boiler, the steps of this boiler service are mostly the same. The engineer may need to make small changes based on the boiler type. Still, the main goal will always be to check if everything is safe and working the right way for all of us.

Here is what you get in a normal annual boiler service:

• Visual inspection of the boiler casing and internal components
  The engineer takes off the boiler casing and checks all the visible internal components. They look for signs of wear, leaks, or rust. This check includes the seals, wires, and the shape of the boiler. Finding and fixing small boiler repair issues now stops bigger problems later.
• Testing gas pressure, controls, and emissions
  A gas boiler must have good gas pressure to work safely. The engineer looks at the gas pressure, then tests the system’s settings, safety controls, and thermostat. They want to check that all parts work the right way. The engineer also looks at how the boiler burns fuel and checks its emissions to make sure it runs safely and as it should.
• Inspection of the heat exchanger, burner, and ignition system
  The heat exchanger is one key part inside the boiler. A crack or block in the heat exchanger can cause a lot of problems and can be dangerous. The engineer checks the burner, pilot light, and ignition system. They clean these parts and check for faults or any signs of wear. This keeps the boiler safe for use.
• Checks for gas leaks and signs of wear
  A gas leak, even if small, is very risky. The engineer uses tools to find any gas leaks. All pipes and joints are checked to make sure they are tightly sealed. If you have an oil boiler, the fuel lines and nozzles are checked the same way.
• Assessment of hot water production.

Why is this important?

Getting your heating system checked can help lower the chance of a boiler breakdown. It also gives you peace of mind. You know your heating system is safe to use for another year. A good checkup can spot things like worn seals, blocked filters, or burning problems early. This lets you fix small things before they turn into big issues. In the long run, it helps you avoid emergencies and save money on energy bills.

Boiler service vs boiler cover

One-off Annual Service

• Cost: £80 – £130
• You make a payment one time each year.
• This is for checks only. If there are repairs, they will be an extra cost.

Boiler Cover Plan

• Cost: £100–£300 each year
• You can choose to pay every month or every year.
• This covers the annual boiler service, repairs, and call-outs. Sometimes, if you need it, you might get a new boiler as part of the plan.

Boiler cover can be a good choice for people who have an old boiler in the house. A boiler that is old may stop working more often. It is always smart to compare boiler cover. This helps you get the best deal.

Why regular servicing saves money

Booking an annual boiler service is not just something you have to do. It can also help you save money at home. A boiler is one of the most expensive things you will have in the house. If you do not get a boiler service, it could lead to bigger bills and repairs that cost a lot. A yearly boiler service helps make sure your boiler works well and does not stop working.

Here is how regular boiler servicing can help you save money as time goes by:

Getting regular boiler servicing can be good for you and your home. A boiler that has been looked at often will work better and last longer. This means you spend less money on repairs or a new one. When you have boiler servicing, the machine will use less energy, so your bills can go down. A well-serviced boiler can keep you, your family, and the people with you safe. Small problems that could get bigger over time are seen early on when you get regular boiler servicing. This can stop you from having to pay a lot later. Overall, looking after your boiler is an easy way to keep it running well and save money over the years.

• Lower energy bills from improved efficiency
  If you do not take care of your boiler, it will have to work much harder to keep the central heating system and hot water running. Some problems, like blocked filters, broken seals, or burnt-out parts, can use up more energy. A safe engineer can clean and fix these things during regular servicing. This helps your boiler use less fuel and waste less energy. Even a small change over one heating season can help you save some money on your energy bills.
• Protection of your warranty or manufacturer guarantee
  Most new boilers come with a warranty that can last up to ten years. But you have to be able to show proof of annual servicing with a gas safe engineer or OFTEC technician. If you forget to do this, your cover may not be there anymore. Then, if your boiler breaks, you will have to pay all the boiler repair costs yourself. Sometimes, this can cost several hundred pounds.
• Reduced risk of unexpected boiler breakdowns
  A boiler breakdown during winter months is a big problem and costs more. When it is cold, more people call for repairs, so the price to come out will go up. A regular maintenance visit with a safe engineer or gas safe engineer will let them find small problems, such as low gas pressure or parts that are worn out. If you catch these early, it will stop bigger issues with your heating system or central heating.
• Avoidance of emergency repair costs such as a sudden boiler breakdown.

Regular servicing vs. reactive repairs

Think of a boiler service like you would insurance. You pay a set amount of money each year. This can help you avoid big, surprise bills if there is a problem. Some people want to spread out the cost. They may use a boiler service plan or look at other offers to find the best deal. If you choose this, your annual check is included. You will also get help if your boiler stops working out of the blue.

Here is a look at the normal prices in the UK for 2025:

This shows that when you pay about £100 each year for regular servicing, you help stop any big and unexpected bills. These bills can be hundreds or maybe even thousands of pounds. Doing this over the life of your boiler can save you a lot of money.

Example: 10 years of servicing vs. no servicing

To help you see what the numbers show, here is how the costs can go up over ten years.

Scenario 1: Regular servicing

• The service cost for the annual service is £100 each year. You will pay this amount for 10 years. When you add it all together, that will be £1,000.
• You may also have to pay for a small repair at some point. Over the 10 years, this can be £200.
• So, in 10 years, your total cost for all this will be £1,200.

Scenario 2: No servicing

• If you do not get your boiler looked at for five years, it will not work as well. This can make you spend about £100 more each year for energy. So, after five years, you will have lost £500.
• In the sixth year, something can go wrong, and you may have an emergency. A repair like this may cost you £400.
• A heat exchanger could stop working in year eight. You might need to pay £800 to get a new heat exchanger.
• After ten years, your boiler may break all the way. A new boiler installation will cost you about £3,500.
• If you add it up, you pay £5,200 over ten years.

If you have regular servicing, you will spend about £1,200 over ten years. But if you do not have regular servicing, you could end up paying over £5,000. This extra cost is not the only problem. If your heating breaks down in the coldest months, you will feel a lot of stress too.

New boiler vs regular servicing

Getting a new boiler installation in the UK will cost a lot, often between £3,000 and £4,500. The price you pay will depend on the boiler type you choose. If you spend about £100 every year on regular boiler servicing, you can help your old unit keep working for a longer time. Regular boiler servicing also helps the boiler run well. This is a better and lower-cost option than paying for a new boiler.

If you are not ready to get a new boiler, you can look at getting a boiler service plan. You can also compare boiler cover to see what is best for you. A plan like this can help you handle the yearly cost and get help if your boiler breaks suddenly. A boiler service and boiler cover both give you peace of mind.

Service timing and location

• Best time to book: The best time to book is in spring or summer. There is less demand, so prices are lower at this time.
• Winter months: A lot of people book in the winter months. You might wait longer and pay more during these months.
• Location: If you live in London or the South East, you will often pay 20–30% more than people who are in the north.

Why choose a Gas Safe or OFTEC-qualified engineer?

A Gas Safe engineer is the only one who can legally do a boiler service for gas boilers. For oil boilers, you have to get an OFTEC-registered engineer. This is so the job will be safe and done the right way. When you use a safe engineer for your boiler service, it will follow the rules. Your home will be safe because of this.

• You can keep safe from gas leaks and carbon monoxide poisoning.
• You will follow UK laws, and that is important, especially for landlords.
• You will feel better because you know that your central heating system gets checked the right way.
• You will know your insurance policy or your boiler warranty is still good.
