New Boiler Installation Service

If your boiler is on its last legs, it might be time to get a new one. We understand that getting a new boiler installed can be a stressful process that is why we pride ourselves on providing a hassle-free service with no hidden costs. We’ve designed this page to give you as much information as possible and guide you through the process of getting a new boiler.

What type of Boiler do you need?

The first thing we’ll need to know is what type of boiler you need. Don’t worry if you don’t know – lets chat! One of our friendly boiler engineers will be happy to help you to identify the type of boiler you need. There are three main varieties:

Conventional Boiler

Conventional boilers are the most traditional form of heating in the United Kingdom. They require hot and cold water tanks usually in your loft.

System Boiler

System boilers need a cylinder for storing hot water. They do not require a loft tank which has the benefit of allowing you to free up some space.

Combi Boiler

Combi boilers heat water directly from the mains upon turning on the tap, eliminating the need for a hot water storage cylinder or a cold water tank in your roof.

We provide a professional boiler fitting service across London. We understand that you may have several questions when it comes to getting a boiler installed or replaced in your home.
