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.
