New boiler installation in Leamington Spa

The right boiler depends on the house. A two-bed flat off the Parade needs something very different to a four-bed family home in Whitnash or Lillington. So we don’t quote from a brochure. We come and look first.

At the survey we check your hot water use, the number of bathrooms, your water pressure and where the boiler and flue can go. Then we recommend a boiler sized for your home and talk you through the options. If a smaller, cheaper boiler will do the job, we’ll say so.

All the boilers we fit are A-rated. Manufacturer warranties run from 5 to 12 years depending on the model. We register yours before we leave.

Boiler replacement in Leamington Spa

If your boiler is getting on, replacing it can work out better than keeping it going. Older boilers tend to use more gas and parts get harder to find.

A straight swap for the same type of boiler takes one to two days. Switching type, say from a regular boiler to a combi, takes two to four days because the pipework and tanks change too.

Signs it might be time:

Combi, system and regular boilers

Combi boilers

Heat water as you use it. There’s no cylinder, which frees up a cupboard. Best for smaller homes with one bathroom.

System boilers

Keep a cylinder of hot water ready. They cope better when more than one tap is running, so they suit bigger homes.

Regular boilers

Use a cylinder and a cold water tank in the loft. They’re often the best match for older houses, and Leamington has plenty of those.

Gas Safe engineers in Leamington Spa and Warwick

By law, only a Gas Safe registered engineer can work on your gas boiler. That rule’s there for a good reason. Every boiler we install is fitted by a registered engineer. You can check us on the Gas Safe Register before we arrive.

We cover Leamington Spa, Warwick and the surrounding area.

Our focus is new boiler installations and replacements.

Boilers for Regency and Victorian homes

Plenty of Leamington homes have a bit of age on them. Regency townhouses, Victorian terraces, big old houses split into flats. Each one throws up something different. Pipework may be decades old. The boiler might be in a cellar or tucked into a top floor cupboard. Finding a sensible place for the flue can take some thought.

We plan all of that at the survey. If your home is listed, changes such as a new flue position can need listed building consent. We’ll flag it before we quote so you can check with the council first.
