Despite the withdrawal of Green Deal funding, there are still mechanisms that can make energy efficiency works more affordable. For example, private customers of Sustainable Energy Services can still take advantage of 0% finance from Barclays Partner Finance. Sustainable Group (UK) is an accredited broker and can assist clients who require interest-free credit to help pay for energy efficiency improvements, general building work, decorating and repairs.

External Solid Wall Insulation

Although Sustainable Energy Services delivers all kinds of insulation contracts, it has an especially impressive track record in the field of external solid wall insulation. The company is an approved installer member of the Solid Wall Insulation Guarantee Agency (SWIGA), a member of the National Insulation Association and a BBA-accredited installer for external wall insulation projects carried out to the PAS 2030:2014 standard.

Using this experience, the company is able to operate as a main contractor and can handle anything from small, private installations to multi-million pound solid wall insulation contracts.
