What is a contractor?

Energy efficiency measures and technologies include lighting, heating, cooling, ventilation, insulation, and renewable energy solutions.

Contractors are any players in the energy efficiency supply chain. That includes manufacturers, distributors, suppliers, technology and service providers, installers, and more. They can be any size – including individuals and small companies as well as larger contractors. But, we do prefer to work with contractors based in Oxfordshire.

Our service is centred around trust and expertise, so we need contractors that we can rely on to consistently deliver high quality work.

How it works

Where do contractors fit into the process?

Our team initially take clients through a feasibility stage, assessing their premises, identifying the energy efficiency measures and technologies which will work for them, and making sure they’re ready to go ahead.

At this point, we’ll then bring in our Approved Contractors to quote and tender for the work – so you’re accessing a client who is already ready to start work.

Based on this, we’ll decide which contractor is best suited for that project. Our team will then work with them to project manage the delivery and oversee the quality assurance process.

Recommending clients

Did you now that we’re able to support businesses and organisations with the upfront costs of energy efficiency improvements?

We do this by helping them access pre-approved, low-interest loans and finance opportunities, and assessing the cost savings made to make sure that the money saved by reducing energy bills covers any loan payments.

If you have a new or existing client that you think could benefit from this, please get in touch – we’d love to help.
