Contractor to source half its electricity use from renewable sources after signing a supply agreement with EDF Energy.

Contractor ISG InteriorExterior is to source half its electricity use from renewable sources after signing a supply agreement with EDF Energy.

Under the agreement, half of InteriorExterior's electricity will come from generators using wind, landfill gas and hydropower, with the rest coming from conventional sources.

Simon Attwood, head of quality and continuous improvement at InteriorExterior, said that the deal "enables us to reduce our carbon footprint and play a positive role within the communities in which we operate."

"As a company, we believe passionately in developing more responsible and sustainable business practices and we are delighted to be able to introduce green electricity into our own offices and onto relevant projects across the UK."

InteriorExterior is also working on the UK's largest solar power project at the CIS Tower in Manchester, which is cladded with photovoltaic panels.
