Vaillant Boiler Prices
As you would expect there is a significant range of prices across Vaillant boilers depending on the type of boiler (Combi, System, Standard – aka regular/conventional) and the size (power output) of the boiler. Vaillant is on the upper end of the price spectrum for boilers as it is a premium brand and was the winner of our Best Premium Brand Boiler category earlier this year.
On average, a Vaillant boiler can cost anywhere from £800 to £2,500. However, the cost of installation is usually not included in this price and can add an additional £500 to £1,500, depending on the complexity of the installation.
Vaillant Boiler Installation Cost
Installation costs for a Vaillant boiler will vary depending on numerous factors, including the company you purchase your Vaillant boiler from, your regional location, whether it’s a straightforward installation or a boiler replacement that involves the removal of your old boiler, and if you require any additional parts or labour.

Frequently Asked Questions (FAQs)
Are Vaillant Boilers Any Good?
Absolutely! Not only is Vaillant one of the oldest and most recognised manufacturers of heating systems in the UK but they currently have a top rating of “Excellent” on Trustpilot from nearly 20,000 customer reviews.
How Long Does a Vaillant Boiler Last?
According to Vaillant, one of their boilers should typically last between 10 and 15 years. This is conditional on how it is used, how well it is maintained, and if it is serviced regularly or not. If you maintain your boiler well, there’s no reason why you should need a new Vaillant boiler installed anytime before that 10 to 15 year mark.
As you’ll have seen become apparent, it’s hard to put a definitive answer to the question of Vaillant boiler costs, because you’ll always have to purchase your new Vaillant heating system through a third party.
