We have the largest range of renewable equipment available anywhere, and our consistent aim is to provide the highest quality equipment currently available, technically and physically robust. We are constantly trying out new kit ensuring it works to standard. We constantly innovate making sure we are on the cusp of current technical advances.

We can install these systems and equipment for you, anywhere in the world, or you can buy on-line, or we can visit your home and design-up a system fully bespoke solution tailored to your needs. You or your engineers can install and we will provide you with the technical back-up you need - we are very flexible on installation. We are based in the international finance centre of Guernsey and have a Renewable Energy Engineering installation team based in Guernsey and Jersey operating in the Channel Islands able to undertake installations anywhere in the world (see 'Global Task Force')


We pride ourselves being a solutions provider, the biggest difference from now and when we first started in business is that we Do Not do oil or gas solutions anymore. Electricity is the energy of the future and it has to be efficient and it has to be 'renewable'!
