We are solar installers installing solar thermal (hot water) and solar PV (electricity) systems throughout England and Wales. Our head office is in Reading; however we have a network of locally based installation teams to manage installations across the UK. All installers are employed directly by us - we do not sub-contract work out (except scaffolding).

We are a solar PV specialist offering a complete service encompassing design, supply and
installation. Our lead solar installers have fitted hundreds of systems in Spain and the UK,
ranging from small domestic systems to large solar farms.
We are not double glazing salesmen turned solar, nor are we a company of electricians
doing a bit of solar on the side. Our passion is for renewable solar energy and we
have dedicated many years to building up a wealth of experience to become the top
specialists for solar panel installations.

Experienced solar installers
Our installation managers have been installing for several years in this country and overseas and have carried out hundreds of solar installations. You can therefore be assured that your solar panel system will be fitted by an expert installer with a proven track record in the industry.
We can provide testimonial after testimonial from satisfied customers saying how impressed they are with our installation team. You are welcome to speak to previous customers; some of our customers are also happy to show you around their system!
We do not cut corners. We work tidily, trunking loose cables and replacing any tiles should they be cracked whilst we work on the roof.
Structural compliance
We work closely with qualified structural engineers to ensure that we comply with current Building Regulations (in particular Parts A and C). We provide full structural calculations for you and for Building Control to make sure that your roof can take the additional load. We do not take the view (as many of our competitors do) that the load from the solar panels is not material. We know from experience that it is. If your roof needs strengthening we will make sure this is done.
We use German engineered mounting systems which screw into the rafters. Unlike some of our competitors we do not try and do a 'quick job' by hanging the panels like tiles off the roof battens. This would lead to a much quicker installation but the system will only be as good as the screws holding the battens into the rafters - in general these are not designed to take another 150kg load.
Fanatical about customer service
We are totally committed to customer service. Our experienced staff are on hand to answer all of your technical questions. Test us out now - give us a call now on 0845 475 3953 - 9 - 5pm Monday to Saturday. We'll answer within a few rings and give you helpful advice on the fantastic incentive the government is giving you to install solar panels (Feed-in Tariff).
