Extended manufacturer warranties up to 10 years — registered directly with Worcester Bosch on the day of installation
Worcester Bosch Accredited Installer status isn't held by every heating engineer. To qualify, engineers must meet Worcester Bosch's own standards for training, installation quality, and customer service — and that status has to be maintained, not just earned once.
For you as a customer, the most tangible benefit is the extended manufacturer warranty. A standard Worcester Bosch warranty through a non-accredited installer is typically two to five years depending on the model. As an Accredited Installer, I can offer extended warranties of up to 10 years — registered directly with Worcester Bosch on the day your new boiler is commissioned.
This is a manufacturer guarantee, not a third-party warranty or insurance product. It's Worcester Bosch standing behind the boiler they made, with an engineer they've approved. If something goes wrong within the warranty period, you deal with Worcester Bosch directly — not an intermediary.

I install the full Greenstar range. Below are the two models most commonly fitted — I'll advise which is the right choice for your home during the survey visit.
A reliable, well-proven combi boiler that suits the majority of homes. Compact enough for a standard kitchen cupboard, simple to operate, and efficient enough to achieve an ErP A-rating. A good all-round choice for like-for-like replacements and properties with one bathroom and moderate hot water demand.
Worcester Bosch's top-tier combi range, with higher efficiency ratings, quieter operation, and full compatibility with smart thermostats and the Wave controller. Better suited to larger homes, properties with two or more bathrooms, or customers who want the best available performance and connectivity. Available in a wider range of output sizes.
Not sure which model is right for you? I'll assess your property, hot water usage, and existing pipework during a free survey visit and give you a clear recommendation before any commitment. See also the boiler replacement page for more on the installation process, or compare with Vaillant accredited installations and Baxi boiler installation.
"Nicholas is a true professional. He has completed a couple of jobs for me where previous engineers had given an incorrect diagnosis or said they could not fix the issue. He is very knowledgeable, clearly knows his trade, and I'm glad I found him to resolve my problems."
It means I've met Worcester Bosch's requirements for installation quality and training. As an accredited installer I can register extended warranties of up to 10 years directly with the manufacturer — longer than you'd get through a standard installer.
