There are numerous makes and models of boiler available in the UK, but Cosy Abodes tends to advise its customers to choose from four heating company brands – Worcester Bosch, Vaillant, Baxi and Glow-worm.

Each offers something a little different from the next in terms of quality, warranty, reputation and cost.

To make sure you select the best boiler for your property and budget, here is Cosy Abodes’ review of each boiler brand so you can make an even more informed purchase.


Worcester Bosch has made boilers since 1962. The company is part of the Bosch Group.
