The Green Deal Home Improvement Fund (GDHIF) is a publicly funded scheme designed to help private homeowners in England and Wales with the costs of installing solid wall insulation. It operated briefly between June and July 2014 but was quickly closed by the Department of Energy and Climate Change when it reached its £120 million budget allocation. However, in December 2014, DECC reported that it would be re-opening the scheme on 10th December and that it would release additional funding in quarterly tranches thereafter.

The scheme will fund up to 67% of the costs of fitting solid wall insulation, subject to a maximum of £4,000, rather than the £6,000 previously allowed. It will also provide up to £1,000 to cover the costs of installing two other eligible measures, which include examples such as cavity wall insulation or fitting a new condensing gas boiler.

Please also be aware that the original Green Deal scheme is still running and can still help customers to pay for a raft of energy saving works, including solid wall insulation. More details can be found on the Sustainable Energy Services website.

In addition to conventional Green Deal funding, customers can also take advantage of 0% finance from Barclays Partner Finance. The Sustainable Group 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 Green Deal Installer for external wall insulation projects carried out to PAS 2030:2012.

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.

Sustainable Communicates With ResidentsDomestic and Commercial Clients

Please note that Sustainable Energy Services works exclusively with domestic clients and that Green Deal funding is applicable only to private homeowners in England and Wales. However, Sustainable Building Services (UK) Limited offers the same design, installation and project management services to commercial clients such as landlords, developers and housing associations.
