Customer reviews

  • I had to exchange the hot water cylinder and Aspect didn't disappoint - Andrew was professional, knowledgeable and trustworthy! A Customer Service Representative kept me updated on payments and delivery dates and also sorted out the warranty for me!

  • The two gas engineers who came to install my combi boiler were very professional and friendly.

  • When I complain I complain. When I praise I praise... So I just want you to know that I was very happy with today's visit from Rafal your gas engineer. He was polite, extremely quick in resolving the problem and explained things very clearly. I felt confident in him and hope that he'll be able to attend to any future works we do with Aspect.

Benefit from an extended warranty

We’re independent and can install almost any type of domestic gas boiler. Despite this, we install far more Worcester Bosch, Vaillant and Ideal boilers than any other brands. Based on our experience we regard them as the most reliable domestic boilers to choose from.

Aspect is part of the Worcester Accredited, Vaillant Advance and Ideal Recommended installer programs. When we install a boiler made by any of these leading manufacturers you benefit by getting an extended warranty period. Depending on the model, the warranty is automatically extended by between 2 to 5 years.

When you’re choosing your new boiler we’ll let you know about options to increase the warranty even further.

You’ll be provided with installation certificates to show the boiler has been installed correctly and have been fully tested. Our gas engineers will do everything they can to keep your boiler running trouble-free for years to come.

Our guarantee and accreditations

We’re fully trade accredited. Aspect is registered with Gas Safe and is a member of the Building Engineering Services Association (BESA). In addition, the Aspect Guarantee covers our tradesmen’s workmanship for up to 12 months.

When you book Aspect for a new boiler installation you can count on getting the professional expertise you’re looking for.
