Replacing your boiler with Vaillant
Vaillant was founded in Germany in 1874 and builds its UK boilers in Belper, Derbyshire. Its ecoTEC boilers have been a common sight in British homes for years, and the brand is known for quiet running and fine control over heating output.
We fit Vaillant boilers as like-for-like replacements, combi conversions and system boiler upgrades. The compact ecoFIT pure suits kitchens where cupboard space is tight, while the ecoTEC plus covers bigger homes and higher hot water demand.
The online quote shows the Vaillant models that suit your home, with one fixed price for the whole job.
Vaillant’s gas boilers fall into a few clear ranges, each suited to a different kind of home.
| Model | Type | Best for |
|---|---|---|
| ecoFIT pure | Combi, system or regular | Smaller kitchens and cupboards; compact and quiet |
| ecoTEC pro | Combi | Straightforward combi swaps in small to mid-sized homes |
| ecoTEC plus | Combi, system or regular | Mid-sized and larger homes, with a wide choice of outputs |
Outputs and availability depend on your home, so your online quote only shows the Vaillant models that suit it.
The price of a Vaillant installation depends on the range and output you choose and the work involved. Across all brands, like-for-like combi swaps start from £1,759 fitted; an ecoTEC plus system boiler with a new cylinder, or a move from a tank-fed system, costs more.
Every quote is fixed, so nothing is added after the survey. You can also spread the cost: as an example, a £1,799 boiler over 10 years at 9.9% APR works out at £23.26 a month, subject to status.
The ecoFIT pure is built for compact spaces and is a good like-for-like option where the old boiler sits in a wall cupboard.
The ecoTEC plus comes in higher outputs and as a system boiler, so it pairs well with an unvented cylinder in larger homes.
Vaillant boilers can be paired with the brand’s own smart controls and app, so you can manage your heating while you are out.
It depends on the model, its output and the work involved. Across all brands, like-for-like combi swaps start from £1,759 fitted, and your online quote shows a fixed price for the Vaillant boilers that suit your home.
