Vaillant is the boiler a lot of engineers quietly choose for their own homes. German-engineered, the ecoTEC range has a reputation for quiet, efficient, long-lived running, and it sits at the premium end of the market for good reason. As with any boiler, the install is half the story: a great boiler fitted poorly is still a problem, which is why the quality of the engineer matters as much as the brand.

The right Vaillant, fitted properly

LMB fits the Vaillant range across Bridgend, Cardiff, Barry and the wider area, matching the boiler to your home, your hot water demand and your budget rather than selling up by default. The work is done to Vaillant's specification by a Gas Safe registered engineer, with the system set up to run efficiently from day one.

Installations start from £1,900, with a fixed fitted price available online in about 90 seconds and no sales visit required. The price you agree is the price you pay, backed by a public record of 207 Google reviews at a straight 5.0. Where a Baxi suits the home and budget better, that is recommended instead, honestly.

Questions people ask

Are Vaillant boilers worth the money?

How much is a Vaillant boiler installed?

Installations start from £1,900, with a fixed fitted price available online in about 90 seconds and no sales visit needed.

Do you fit the Vaillant ecoTEC range?

Yes. The Vaillant range is fitted to manufacturer specification by a Gas Safe registered engineer, with the boiler matched to your home and hot water demand.

Vaillant or Baxi, which should I choose?

It depends on the home and the budget. Both are fitted, and you get an honest recommendation rather than a default upsell. The combi-versus-system and brand questions are talked through before you commit.
