Willis Renewable Energy Systems


In today’s environment, energy is more vital to us than ever before. We use energy in different forms to produce heat and light in our homes. However for too long we have relied heavily on the earth’s resources of fossil fuels of coal, gas and oil. Our dependence and use of these fossil fuels has had a dramatic effect on the earth’s climate. The UK’s energy supplies in the years to come will be increasingly dependant on imported gas and oil from Europe and beyond.

At Willis, we have recognised the need to develop and understand renewable energy in it’s many different forms. Over the years we have applied our engineering experience to a wide range of renewable energies including solar, geothermal, combined heat and power. We have the expertise to design and incorporate renewable energy systems into a wide range of engineering applications in the domestic and commercial sectors.

Recognised throughout the industry as pioneers in innovation, Willis have formed alliances with a number of the World’s leading manufacturers in renewable energy systems, to provide expertise in Solar systems.
