Our Services

Boiler installation covers everything from taking out the old unit to setting up the controls and balancing the radiators. We size the boiler to the property rather than fitting the biggest one available. Most installs are finished in a day. See our boiler installation page for how it works.

Boiler replacement suits homes where the existing boiler still runs but costs too much to keep repairing. We keep the existing pipework where it is sound, which cuts both the disruption and the price. The old unit leaves with us. More on our boiler replacement page.

A new boiler quote should tell you the make, model, output and exactly what is included, not just a single figure. We look at the property, the radiators and the mains water pressure before quoting. There is no charge for the visit. See our new boiler quotes page.

A combi boiler heats water on demand, so there is no cylinder and no tank in the loft. It suits flats and smaller houses in Kingston upon Thames with one bathroom. We check your mains pressure first, because that decides whether it will work. Read our combi boiler installation page.

System boilers work with a hot water cylinder and suit larger homes where two showers might run at once. They hold pressure steadily across the whole property. We fit, fill and commission the system from start to finish. Our system boiler installation page explains the difference.

Boiler supply and fit means one price covering the boiler, the labour, the parts and the paperwork. You are not left buying a unit yourself and hoping it is the right one for the house. The warranty is registered on the day. See our boiler supply and fit page.

Frequently Asked Questions

How much does a new boiler cost in Kingston upon Thames?

It depends on the type of boiler, the output your home needs and whether the pipework has to move. A straight combi swap sits at the lower end, a full system change at the higher end. We give a fixed written quote after seeing the property, with nothing added later.

How long does a boiler installation take in Kingston upon Thames?

Most straight swaps take a single day. Moving the boiler to a different room, or changing from a system boiler to a combi, usually takes two. We tell you which applies when we quote, so you can plan around the heating and hot water being off.

Which boiler is best for a flat in Kingston upon Thames?

A combi boiler suits most flats because it does away with the cylinder and the tank, which frees up cupboard space. If you have two bathrooms or low mains water pressure, a system boiler with a cylinder may serve you better. We test the pressure before recommending anything.
