Boiler Service

Boiler Service

Heppelthwaite the Red Van Plumbers provide a comprehensive boiler service. Our boiler service takes approximately 1 hour and is undertaken by a fully qualified registered gas safe engineer, who is directly employed by us (not subcontracted).

It is highly recommended that you have an annual boiler service to ensure safety and to prevent nasty repair bills. If you still have a boiler warranty, then make sure you check the small print as it may be a requirement to have an annual service to validate the warranty.

To book an appointment please call 01628 533 550

Why have a Boiler Service?


Aside from ensuring an on-demand supply of heat and hot water, keeping on top of boiler maintenance is a good idea for a number of reasons:

  • Gas safety – Carbon Monoxide can kill
  • Recommended by Gas Safe Authority
  • Helps to reduce gas bills and maintain the efficiency of the boiler
  • Helps to prevent boiler breakdowns and nasty repair bills
  • Prolongs the life of the boiler
  • It is compulsory for most manufacture warranties
  • It is the law for landlords that gas appliances are checked

Manufacturer and Gas Safety Authority Recommendation

It is highly recommended by boiler manufacturers and by the gas safety authority (Gas Safe) that all gas fired boilers are serviced on an annual basis. This is predominantly to check the safe operation and test for Carbon Monoxide leaks, but will also help improve the efficiency and extend the life of your appliance. Regular maintenance can also help prevent a system breakdown, which can be expensive to repair.


Check your warranty as most boiler manufactures will require you to have an annual boiler service to validate the warranty.

Additional Extras

Not All Boilers Are The Same

Not all boilers are the same. However our team of engineers are experienced and qualified to work on all types of boilers. For example, specialist training is required for engineers to undertake LPG, Oil and Biomass boiler services.

LPG stands for Liquefied Petroleum Gas (or Liquid Petroleum Gas), which is an alternative central heating option that is becoming increasingly popular with domestic property owners in the UK. It’s designed as a safe alternative to regular gas, oil-burning or biomass boilers. LPG can be stored in cylinders or tanks on any property large enough to house it. LPG can even be delivered direct from a pipeline straight to your heating system depending on the areas in which you live, although most LPG users don’t have access to piped gas. Find out more

Oil central heating system work similar to a gas-powered counterpart, using an oil-fired boiler to heat water provides the central heating via radiators.

Biomass heating systems work by burning renewable fuel such as locally produced wood pellet, chips or logs. These boilers are designed to provide heat using an existing ‘wet system’ (eg through radiators) and provide hot water to a home. Heppelthwaite the Red Van Plumbers are specialists in renewable energy services, and are MCS approved and registered with REA (renewable energy assurance).

Commercial heating systems are more complex and require specialist training, Heppelthwaite the Red Van Plumbers have a team dedicated to commercial installations and services.
