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.
Do I need boiler and central heating cover? What is it for?
Boiler and central heating cover is a type of home insurance that you can claim if your boiler and/or central heating stops working. It usually covers call out fees and the cost of repairs.
British Gas has it’s own boiler and central heating cover which means that if you have a problem on your system you can call us and one of our engineers will come to your home to fix the problem for you. If, in the middle of winter your radiators don’t come on or you find you have no hot water, you have the peace of mind that we will come and sort it out and cover the costs of the parts and labour.

How much does it cost to service an oil-fired boiler?
An oil boiler generally costs more to install, run and service, but if you live in a rural area which isn’t on the gas mains, this may be your only choice. The average cost of oil boiler service will vary depending on where you live and the make of your boiler:
According to MoneySavingExpert the average cost to service an oil boiler is £230
Fixed price boiler repairs or One-off boiler repair cost
When servicing your boiler, an engineer may find that you need some repair work done. If this is the case, it may be a good idea to negotiate a fixed price boiler repair. Shop around for the best fixed price boiler repair prices; for example:
British Gas fixed price boiler repairs starts from £79.
British Gas one-off boiler repair cost ranges between £79 and £459, depending on the time required for the boiler engineer to complete the project. Expect to pay from £79 or £89 for 30 minutes, £199 or £238.99 between 30 minutes and 2 hours and £409 or £459 anywhere over 2 hours.
Homeserve fixed price boiler repairs start from £210
The one-off boiler covers the following boiler issues:
- leaks or breakdown
- Heating exchanger repair
- Motorised valve replacements.
- Temperature or timing controls replacement.
Arranging a boiler service
You should have your boiler serviced every year, or more frequently if advised by the boiler manufacturer. Make sure you hire the right boiler service engineer for the job:
Gas boiler service – by law anyone who installs, repairs or services gas appliances must be registered with Gas Safe
Solid fuel boiler service – For a wood or coal burning boiler hire a HETAS registered engineer to safely carry out your boiler service. HETAS advise regular cleaning of your chimney and flue in addition to boiler checks
Oil boiler servicing – Ideally, you should have your oil boiler serviced by an OFTEC registered engineer.

Key things to look for
Any work you have done should be carried out by a registered Gas Safe engineer. This is the most important factor, price is secondary to the standard of service you will receive.
In the UK only Gas Safe Registered engineers are permitted to work on boilers. This ensures that the work is done safely and you can be sure of the same high standard across the board.
Your boiler repairman should have a Gas Safe Register card with a yellow triangular symbol. He will be happy to show you this.
Boiler service grants
Not everyone is aware that there is a helpful range of government grants for central heating boilers. Depending on whereabouts you live in the UK, there are different grants for central heating systems for which you could be eligible; including central heating grants for pensioners and central heating grants for disabled people.
