One-off vs Boiler Cover

A boiler service is normally categorised into either a one-off service or an annual boiler cover service.

Boiler Brands

The price of servicing your boiler can differ depending on the brand of boiler you have. As demonstrated by the one-off boiler service price table above, the price is often higher when the service is carried out by the manufacturers own team as opposed to a local and trained independent technician.

If repairs are required, the brand of your boiler can also further influence the overall costs. Replacement parts for high-end boilers, such as Worcester Bosch or Vaillant, will be costlier than cheaper brands, such as Glow Worm and Baxi.

Other Pricing Factors

There are many more factors that can influence the cost of a boiler service. Below are a few tips to keep in mind when booking in a service.

Service in summer for cheaper prices: As you might expect, heating specialists are kept busiest during the winter months. When it is colder, boilers are used more frequently and have to work harder to keep your property warm, so breakdowns and faults occur more frequently. As such, booking your annual boiler service in over summer can often get you a better deal, as boiler technicians are less busy and often offer discounts to earn your business.

Service your boiler regularly: Boilers are an extremely important part of any home, providing heating and hot water throughout the year. If your boiler develops a problem, it can often be costly and slow to have repairs carried out. Regular boiler servicing can help prevent faults developing, and it vital to ensure your working efficiently and safely. It is recommend that you have your boiler serviced at least once per year. 

Request multiple quotes: Prices for boiler servicing can vary greatly between companies. If you want a cheap boiler service, money saving experts always recommend requesting at least 3-4 quotes from different companies. This will give you an idea of pricing in your area, and will help you find the best boiler service for your budget and home. We can help get the ball rolling – request a quote today!

Prices differ across the UK: Throughout the UK, prices for boiler services can differ. Typically, the highest boiler service prices are in London and the South of England. Also, locations without a nearby boiler and heating specialist can also incur higher servicing fees due to the added travel time. Comparing quotes from multiple boiler specialists is the best way to find the cheapest prices in your area.

Cost of Servicing Different Boiler Types

The type of boiler in your home can influence the cost of a service. Both the fuel type (gas, electric, etc.) and the boiler type (combi, conventional, system, etc.) can influence the price of an annual service.

To find out exactly how much a boiler service costs for your boiler type, please use our quick price checker.

Gas Boilers: One of the most common types of boiler used in the UK. They are powered by a gas supply, which is burnt to heat water for central heating and hot water taps.

Electric Boilers: Electric heaters are a common alternative to gas boilers, especially if there is no gas supply to the property. They use electricity to heat hot water for taps and central heating.

Oil Boilers: An oil boiler works in a similar way to gas, as it ignites to heat water for use around the home. Oil boilers typically have an onsite oil tank, which supplies the boiler. 

Combi Boilers: The most popular boiler choice in modern homes, combi boilers are compact and efficient. They directly supply both the heating and hot water supply throughout a property. 

System boilers: A system boiler heats hot water and stores it in a storage cylinder, which is normally placed in an attic or airing cupboard. They directly heat the central heating.

Conventional Boilers: Also known as traditional boilers, these boilers use a water storage tank and a cylinder. They can require a large amount of water to multiple taps simultaneously.

What happens during a boiler service?

The checks carried out during a boiler service will differ slightly, depending on the boiler brand, type and the fuel it uses. The engineer will remove the outer casings to inspect the components to ensure everything is working safely and efficiently.

Below is a general overview of the checks an engineer carries out during a gas combi boiler service.

  • The boiler controls are checked & adjusted, if required. Seals are checked for leaks & cracks. Fans, internal components, electrodes and electrical connections are inspected & tested. 
  • The engineer will check that the boiler has the correct gas pressure & flow. A flue gas analyser is used to check the boiler is burning the right mixture of gas & air. The flue is checked to make sure it is clean and free of debris.
  • The condensate trap and pipe are checked and cleared of blockages. Water & gas pipework is inspected. Boiler safety devices are then tested to check they are working correctly. 
  • Throughout a boiler service, the engineer will be looking for any signs of leaks, rust or corrosion.

It is important that you never carry out repairs or maintenance on your own gas boiler. Gas can be extremely dangerous, and all related work must be conducted by a Gas Safe registered technician. All of our gas boiler specialists are gas safe registered and approved.
