Boiler Service Cost – An Overview

If you are planning to service your boiler, to ensure that your old boiler continues to work or because you’ve moved into a new house, our boiler service cost guide will provide excellent information about boiler servicing costs for different types of boilers, including oil boilers and central heating boilers.

What are the advantages and disadvantages of an oil boiler?

The advantages to having an oil boiler include being able to change supplier whenever you choose as well as the ability to select from a wide range of appliances.

One of the main disadvantages of having an oil boiler is that some of the leading insurers will not cover an oil boiler storage tank.

Additionally, oil boiler installers do not have to be OFTEC registered, so there is no overall governing body such as Gas Safe to protect homeowners.

Annual Boiler Service

An annual boiler service cover ensures that your boiler is serviced regularly to function properly. Boiler servicing is a very responsible job that should only be carried out by a Gas Safe registered engineer. If your boiler warranty is still valid, an annual service is still included in it. Always ask to see the engineers Gas Safe ID.

What is included in a boiler service?

Firstly, the engineer will need to look at the inside components to check that it is all working properly and complies with all the safety requirements. To do this they will remove the outer casing. They will then check:

  • The gas is operating at the correct pressure and flow. Check the Flue and the combustion. The engineer will want to make sure that your boiler is burning gas and air at the correct mixture. They do this by using a flue gas analyser.
  • Electrics – all the connections should be clean and working properly. The condition of the electrics will be thoroughly checked.
  • All the key parts of the boiler, including fans will be checked to ensure they are working properly.
  • Seals are assessed for damage and replaced if necessary.
  • All the electrodes will be checked for condition.
  • Any integral safety devices are checked.
  • The engineer will look for blockages in the condensate trap and in the pipes and take any necessary action.
  • The water and gas pipework will be assessed for safety and function.

Once the service is finished the engineer should give you a written service report, which details the work that they have done. You should have the chance to ask any questions you may have and the engineer will be able to answer these and give you any relevant advice. If at any time between services you think your boiler is not working properly you should contact a registered gas safe engineer.

Monthly boiler cover cost

 Covering your boiler means you are protected if the boiler or it’s controls break. Most boiler cover also includes the cost of servicing but some don’t so always check the small print. Boiler insurance usually costs between £60 to £100 a year and is paid on a monthly basis. Here are the costs of some of the more common boiler cover policies:

  • British Gas charges from £12 per month
  • CERTI UK costs from £13.50 per month
  • EDF Energy from £13.29 per month
  • Homeserve from £13 per month
  • Scottish Power from £13.13 per month
  • Your Repair from £9 per month
  • 24/7 Home Rescue from £9.60 per month
  • Swale Heating from £6.66 per month
  • Gorgi Home Plan from £6 per month +3 months free
  • SSE Boiler Breakdown Cover £4.95
  • NPower Boiler Cover from £10.92 per month

If you don’t want to go for a standalone policy to cover your boiler, sometimes you can add this onto your existing home insurance. In many cases this is sold as an add-on service known as ‘Home Emergency Cover’. This often works out a lot cheaper – around £5 a month – compared to the standalone boiler policies.

Be sure to check that the insurance covers your specific boiler as some have restrictions on boilers such as the Megaflow boiler or other unvented systems.

One-off boiler service cost

Your boiler manufacturer or energy supplier may provide you with an annual boiler service, if not; you’ll need to independently hire a boiler engineer to service your boiler. The average boiler service cost comes to £71, however, according to Energy Saving Trust (EST) the cost of a boiler service can range from £50 to £100; more specific one-off boiler service costs are detailed bellow:

  • Npower boiler servicing prices start from £99.
  • British Gas charges from £79 for a boiler service check.
  • EDF Energy boiler service starts from £80.
  • Homeserve charges £80 for one-off boiler service.
  • Baxi annual boiler service price starts from £96.
  • Worchester-Bosch service cost starts from £90.

Benefits of having a boiler service

The benefits of having your boiler serviced tend to outweigh the average boiler service cost:

Save money on repairs – Your boiler should work perfectly and efficiently; a boiler service engineer will make sure your boiler is working correctly and pick up on any minor faults, which if left unrepaired, could cause major problems in the future. Servicing your boiler could save you money on larger repair bills and emergency call-out fees.

A boiler service could save your life – a faulty boiler can be extremely dangerous; around 20 people die every year in the UK from Carbon Monoxide (CO) leaks caused by faulty gas boilers and appliances; reports the Health and Safety Executive. A regular boiler service will detect any CO leaks, keeping you and your family safe from CO poisoning.

Reduce your fuel bills – A boiler service engineer will make sure your boiler isn’t wasting energy; this can save you money on your fuel bills as well as cut your household carbon emissions.  A boiler service may cut your heating bills drastically. It should save you money in the long run so that you don’t need to fully replace it

A Service may ensure your insurance is valid – Many boiler warranties require you to have your boiler regularly serviced.

Stay legal – landlords are legally obliged to service boilers in their rental properties every year and must provide a valid Gas Safety certificate for gas boilers.
