Warranties and Aftercare Comparison

Most boiler brands offer a warranty with their boiler but Worcester Bosch offers a guarantee as well as a warranty it is one of their most enticing selling points.

This guarantee is an agreement from the manufacturer that they will repair or replace your boiler as soon as possible in case anything goes wrong, unlike other boiler brands it is not an agreement to repair the boiler free of charge.

All Worcester Bosch boilers purchased via Boiler Central, for example, come with up to a 12-year warranty whereas Baxi only offers a 7-year warranty on most of their boilers, such as the Baxi 600 model.

To validate your warranties and guarantees your boiler has to be annually serviced and by an approved boiler installer.

What is the price difference between a Baxi and Worcester Bosch?

The deal-breaker can most often be the boiler price when it comes to purchasing a boiler, this all can depend on the model you choose.

Overall as a market-leading brand, Worcester Bosch is just a little bit more expensive than Baxi. Some would say Worcester is the best boiler brand in the UK.

You can pay between £800 – £1000 for the Worcester Bosch Greenstar 25i (that can only be the boiler and not including the installation, accessories or flue).

Worcester Bosch can be slightly more expensive compared to a Baxi 600 that can cost between £700-£1000, but the high the warranty/guarantee on the boiler the more pounds you can save on boiler repairs. You can always spread the cost of your boiler with a boiler finance plan.

Baxi vs Worcester Bosch Boilers: And the winner is….

For decades both Worcester Bosch and Baxi have been around and accumulated thousands of positive reviews but we think that Worcester Bosch has the edge over Baxi.

Worcester has won the Best Buy Award 10 years running with Which? 

We would probably choose the Worcester 4000 – Read our Worcester 4000 review here for more information on this combi and system boiler. This will set you back around £1,950 fully fitted.

If you are looking for something a little cheaper in the Worcester range, then this Worcester 2000 boiler review will help you, coming in at £1,795 fully fitted.

If you are looking for a regular / heat-only boiler, then maybe go with the Worcester Ri range.

With a brilliant range of boilers including the Greenstar Compact which is ideal for kitchen cupboards, Worcester Bosch boilers also come in different dimensions and power outputs.

They have readily available parts in the UK and offer not just a warranty but a 10-year guarantee, whilst Baxi only offers a 7-year warranty as standard.
