How Much Does A Boiler Service Cost?

A boiler service will cost £81.00 (inc VAT) for a standard gas boiler service.  If you’re looking to get your oil boiler serviced, find out more about our oil boiler service cost here.

Worcester boiler servicing

Because we’re Worcester Bosch service partners, there’s no one better to service your Worcester boiler. All our engineers have attended the Worcester training academy where they’ve had training on all Worcester boilers.

If your Worcester boiler is under warranty, we can also carry out service work on behalf of Worcester Bosch. That means if we spot any problems during your service, we can get them sorted for free under your Worcester warranty.

Worcester full service

Worcester recommend a full service on your boiler every 5 years. During a full service the boiler is fully stripped down, cleaned and rubber seals and electrodes are replaced. We’ll also adjust the gas valve settings so your boiler will be left working as well as it was on the day it was installed.

This is only a recommendation by Worcester Bosch, failure to do so can lead to more expensive repairs in the future.

 The cost of a Worcester full service varies between models:

  • Worcester CDi or CDi Classic boiler – £232
  • Worcester Ri, Si combi, i Combi, I System, i Junior boiler – £166
  • Worcester CDi compact and Si compact system boiler – £170

Worcester service plan

If your Worcester boiler is under warranty, you’ll need to get it serviced every 12 months in order to keep the warranty. Why not take advantage of our Worcester service plan for only £7 a month?* You can still join the plan even if your Worcester boiler is out of warranty.

*£60 joining fee to cover the cost of the initial service

Extra appliances

If you have additional gas appliances (such as a second boiler, gas fire or gas hob/oven), you can also have those serviced at the same time as your boiler, which would reduce the cost of having them serviced separately.

Does a one-off boiler service cost more?

If we haven’t serviced your boiler before, or you haven’t had your boiler serviced in the last year or two, don’t worry. We can get your boiler and system checked over and issue a 12-month safety certificate for the same price as our standard boiler service. And we’ll even add you to our service reminder list, so you never need to worry about missing a boiler service again.

How often should I get my boiler serviced?

At The Boiler Service Company we recommend getting your boiler serviced every 12 months, to keep it working properly and efficiently. If your boiler is under warranty you’ll need an annual service in order to keep your warranty valid.

Boiler under warranty service

In order to keep your boiler warranty valid, all manufactures insist on getting your boiler serviced every 12 months. We carry out warranty services for a fixed price, regardless of what boiler you have.

After your service we’ll give you a Gas Safe certificate, and provide a receipt with a description of work for the manufacturer as proof of service.

A lot of boiler manufacturers won’t honour their warranty unless your boiler has been serviced for the last 12 months. If you’ve missed a boiler service don’t worry, one quick call to the manufacturer can confirm if your warranty is still valid. If it’s a Worcester Bosch boiler, we can sort it all for you as Worcester Bosch service partners.


Sometimes there is more that you might want doing than just the boiler service, more copy here.

Adding a chemical cleaner to the system £65*

If there’s sludge in your system, it’s likely your boiler will eventually stop working altogether. That’s why, if there are signs your system is dirty, we’ll recommend a chemical cleaner to remove the sludge in your central heating system. Once we’ve added it to your system, simply use your central heating as normal for the next two weeks, then we’ll come back to drain it down and add an inhibitor to stop the build-up of more sludge.

The signs of dirt or sludge in the system are:

  • Black substance when bleeding or venting radiators
  • Cold spots on radiators
  • Brown sludge in the heater tank
Power flush £440*

Sometimes a system can be so sludged up that a chemical flush won’t work and we’ll need to use something more powerful. In this case we’ll use a power flushing machine, which can shift most blockages. This will take a full day to complete.

Magnetic System Filter £130*

Magnetic filters, or boiler filters, are fitted to your boiler’s central heating return pipework, extracting any debris or sludge from the water so that there isn’t a build-up, which can damage the boiler or restrict the flow of water.

Deaerator £115.00*

The main reason for sludge build-up in central heating systems is excess air, mixed with steel in the radiators and dirty central heating water. This will result in the system rusting. Deaerators can stop that from happening, but they’ll only work if your system is clean. So if the system is relatively new you may be better off with a deaerator rather than a magnetic filter.

Scale Reducer £60*

If you’re in a “hard water” area, you may notice a lot of scale build-up on your taps and inside your kettle. The same thing could be happening inside your boiler, meaning a high chance of limescale build-up destroying expensive boiler components. Our scale reducer treatment can help remove and prevent limescale build-up inside your boiler.

CO alarms £25*

The HSE strongly recommends the use of audible carbon monoxide (CO) alarms. Carbon monoxide (CO) is a colourless, odourless, tasteless, poisonous gas produced by the incomplete burning of carbon-based fuels. If your boiler is in your living room or a bedroom, it’s a good idea to invest in a CO alarm to help keep your family safe.

*prices are for work carried out at the same time as the boiler service, and are dependant there being space to install, and the suitability of the system.
