It’s always nice when your money goes a long way, isn’t it?

Especially with a big investment like a new boiler, you want peace of mind that you’re covered if anything goes wrong – which is exactly why Worcester Bosch’s 10-year guarantee is so ideal.

Now, if you’ve been paying attention to my blog recently, you’ll probably already know that I make no bones about being Worcester Bosch’s biggest fan, but let me tell you exactly why their guarantees are the best on the market.

A comprehensive package

Most of my customers have been particularly impressed with Worcester Bosch’s 10-year guarantee covering the entire Cdi boiler range, when fitted with the brand’s own controls and heating filter.

It means everything is covered in one nice little package, the boiler controls and filter will all be covered with the 10 year guarantee. And it’s one of the longest guarantees you’re going to find when purchasing your new boiler.

Because although Worcester Bosch is one of the most reliable brands on the market, 10 years is still plenty of time for things to go wrong.

TIP: Don’t forget to get your new Worcester Bosch boiler installed by an accredited installer, as this ensures you’ll get the maximum-length guarantee.


There are plenty of boiler manufacturers out there offering decent guarantees, but it’s annoying when you check the overly complicated small print and discover there’s a catch.

It’s even worse to find out the company managing the guarantee have a mandatory credit card charge for a call-out before they’ve even discovered the cause of the problem.

Worcester Bosch’s guarantee, on the other hand, is what’s known as a ‘no quibble’ guarantee, with no hidden charges or clauses in the small print. Plus, the company has their own dedicated team of engineers who are only experienced in dealing with Worcester Bosch boilers, so you know you’ll get the best possible service.

TIP: You must still have your boiler serviced annually for the guarantee to be valid, so set yourself a reminder and don’t let it get past that date!

Not interested in the CDi range?

No worries. You can still get an incredible nine-year guarantee with Worcester Bosch’s Si boilers, or eight years of cover with the new Greenstar i range – as long as you also fit the Worcester Bosch controls and heating filter, which will be covered, too.

All of Worcester Bosch’s guarantees are no-quibble, and you won’t have to worry about any hidden clauses in the small print.

See? Now everyone’s happy!


It’s nice to know your investment’s protected, which is why I recommend Worcester Bosch’s guarantees to all my customers. I can without a doubt say that it’s the best, most comprehensive guarantee on the market, and you can be reassured there’s no clauses or small print to catch you out.

You can get up to 10 years’ cover on the CDi range, but don’t worry – you’re also covered up to nine years for the Si boilers and eight years for the Greenstar i range.
