Installation across the Llanelli area

We cover the town and the surrounding communities — Felinfoel, Furnace, Pwll, Dafen, Llwynhendy and out towards Burry Port. Llanelli is at the western edge of our area, which suits installation work well: it is planned, booked ahead, and we arrive with the boiler, parts and the day set aside.

The survey comes first

Chris visits before quoting. He checks the radiators and how your household uses hot water, the gas supply, the flue route and the condensate drain, and talks through the options in plain terms.

That survey is what makes the quote accurate. A boiler sized from a photo or a guess is how homes end up with hot water that cannot run two taps, or a boiler bigger than the house needs.

Combi, system or regular?

Most Llanelli homes suit a combi, but houses with two bathrooms in use at once, or an airing cupboard cylinder in good order, may be better with a system boiler. Our combi vs system boiler guide compares them, and the what size boiler do I need guide explains output in plain terms.

Older houses, older systems

Llanelli's older terraces often have heating systems that have grown in stages. A new boiler is the ideal moment to deal with what holds the system back: a system clean, a magnetic filter, thermostatic valves or better controls. These are standard parts of a good installation, not extras to be talked into.

What the installation includes

  • Old boiler removed and taken away
  • System clean and magnetic filter fitted
  • Flue, gas supply and condensate checked and altered as needed
  • Controls set up and explained at handover
  • Benchmark registration and warranty paperwork completed

What drives the price

The boiler model is only part of the total — flue changes, controls, the system clean and any pipework alterations all add up. Our new boiler cost guide explains each factor so you can compare quotes properly.
