Since 1999, Ecolution, also known as Cel-F Solar systems, has installed thousands of renewable systems nationwide on a variety of buildings and roof types. We are one of the UK’s largest and longest standing construction specialists, focusing on the installation of solar photovoltaic (PV), solar hot water (SHW), mechanical ventilation heat recovery (MVHR), air source heat pumps (ASHP) and energy storage solutions.

Our tailor-made services are designed to provide customers with state of the art energy solutions, combined with exceptional customer service. We will work together with you from the initial site assessment to the design and planning stages, to completion, ensuring all your requirements are met and that optimum renewable systems are delivered.

Whilst we have strong relationships with quality suppliers, our complete approach and our independence from system manufacturers allow us to provide the right system for the right project, ensuring that optimum efficiencies are achieved from design to maintenance.

We are always putting our clients and end users needs at the forefront which is which we pride ourselves on our quality installations and exceptional service. Check out our case studies and testimonials to find out more.

Usually, when tendering for all renewable installations, we also quote for the ManSafe and electrical contracts, to achieve economies of scale. Find out how our combined Electrical and ManSafe service packages can help you.
