Boiler Warranty: The Best 10-Year Warranty Boilers in 2020

If you’re looking for a new boiler that won’t break the bank and will last for a long while, the quick guide below will help you shortlist all boiler brands and models that have great warranties.

We’ll focus on boilers with a 10-year guarantee as a minimum.

Why A 10 Year Warranty Boiler?

The difference in price between a boiler with a 10-year warranty, and one with say, 2-years, isn’t much. For a typical 24kw unit, you’d expect the price difference to be around £200.

Essentially, you’re paying £25 per year, for each additional year of warranty. In our opinion, that’s an absolute bargain when you consider the overall purchase could be in the thousands, including installation.

The difference in price will be in relation to the purchase price of the boiler only, and not the cost of labour for the installation; that’s going to be the same.

A typical installation in an average home (24kw-30kw unit) is going to cost around £2,000. It’s hardly worth saving £200 on a low warranty boiler, when you then risk having to foot the bill for a new £2,000+ installation, just a few years down the line.

What’s The Minimum Recommended Warranty?

A boiler with a 5-year warranty is what we’d recommend as a minimum. If a brand is offering a 5-10+ year warranty, that’s suggesting they have confidence that their products have longevity.

A boiler with a 2-year warranty? Not so much…

But, if you have the budget to stretch to a boiler with a 10-year warranty, that’s advisable.

Boilers With a 10-Year Guarantee

Based on our extensive research in the market, these are the top boiler brands to deliver the best guarantee.

#1. Worcester Bosch Guarantee: 10 Years

Depending on the model, you’ll find various installers offering warranties of 5-10 years on Worcester Bosch boilers. This is not only extremely competitive it also shows the confidence Worcester Bosch has in the quality of their products.

But how do you get the 10-years Worcester warranty? We suggest heading over to HEATABLE — one of the most reliable online boiler installation company.

Worcester Bosch Greenstar i from Heatable

They not only offer the best rates on Worcester Bosch boilers (starting at £1,770 for the Greenstar model) , but they’re also able to offer them with a long warranty. At the time of writing, all Worcester boilers listed on their website come with a 10-year warranty.

#2. Viessmann Boiler: 10 Year Warranty

Another strong name in boiler manufacturing is Viessmann. The German company is one of the biggest players in the European market not only because they sell a lot of boilers every year, but because they built them to last. And that’s something most installers will tell you.

Viessmann Vitodens 050-W from Heatable

Viessmann boilers come with a 10 year warranty if acquired from HEATABLE. Prices start at £1,670 for the Viessmann Vitodens 050-W — a popular Which? Best Buy boiler.

  • Baxi 600, the Baxi duo-tec, the Baxi EcoBlue range or the Baxi Platinum
  • Ideal Vogue and Ideal Vogue Max
