Our Services

We specialise in the installation of boilers and renewable energy products from Worcester, using the latest technology available. Modern Worcester condensing boilers improve efficiency to over 90%, which could save you a minimum of 30% per year on your home heating bills and result in a big saving over the lifetime of your boiler. If you already know which boiler you want, our expert engineers will be able to install it for you. Alternatively, if you want some help and guidance, you can arrange a no-obligation visit by one of our engineers who will come to your property to advise you on the best boiler for your home.

Annual boiler servicing is a wise precaution. We can ensure that your current system is operating to peak performance, protect against Carbon Monoxide leaks and prolong its lifespan. Regular maintenance can also help prevent a system breakdown which can be expensive and never welcome. All Worcester boiler guarantees (and many other brands) are conditional on an annual service.

Boilers that are over ten years old waste a lot of valuable energy. No matter what type of boiler your household has, our team of experts can quickly diagnose and repair your boiler using quality components and parts. All work is covered with a 30-day labour and 1-year parts guarantee. If you are experiencing problems with your boiler and would like to book an appointment for one of our engineers to visit, you can request one here.
