FAQ
What is a boiler service?
A boiler service is generally where a registered engineer comes to your home or office and checks the boiler to see if there are any problems with it or whether it needs repairs.
The boiler service might include the following:
- Visual inspection for leaks or corrosions.
- Removal of the casing to check the parts and controls.
- Flue tests for safety.
- Gas pressure checks to ensure that it’s working correctly.
How important is a boiler service?
Having a regular boiler service is essential in making sure that your boiler, and your home, are entirely safe.
Not only can a damaged boiler mean that your heating might not work correctly or give you access to hot water, but it could also be dangerous.
Plus, if you don’t prevent problems with a boiler, you might need to purchase a new one, which could be far more expensive in the long run.

- Your gas is unusually high.
If you recognise any of these ‘symptoms,’ make sure you get your boiler serviced as soon as possible.

Boiler Types
Combi Boilers
A combination boiler is a single unit which is used for both heating your water and operating as a central heating boiler.
These types of boilers heat your water using the mains and don’t need a hot water cylinder.
Combination boilers are often less expensive to run as well, as it heats water instantly.
System Boilers
System boilers do require a cylinder to be able to store hot water for use later on, but all of these components will be built into the same boiler, which makes it easy to install.
These boilers are compatible with systems that are solar powered, which means less environmental damage and a more eco-friendly boiler.
Regular Boilers
Regular boilers are a more traditional type of boiler that uses a hot water cylinder as well as a cold water storage tank to maintain your central heating system.
This might be your preferred option if you have two or more bathrooms.
