More than 3,000 households and businesses across four Norfolk councils have landed savings of up to 19% on solar systems as part of a collective purchasing agreement.

Norwich City, Broadland, South Norfolk and North Norfolk district councils banded together to run the scheme – which works in an equivalent way to online retailer Groupon – to allow residents to commit to purchasing PV in a one-day auction process.

A total of 3,379 households and businesses signed up and the savings offered to participants range from between 11 and 19%, with an average saving of 16% on the current market price.

The Solar Together Norfolk scheme has been powered by collective purchasing platform provider iChoosr and has selected energy efficiency technology installer Job Worth Doing to carry out the work, and all installations will be carried out by individuals based in Norfolk.

IChoosr will now contact all the offer participants throughout the next month in order to provide a personal offer based on their circumstances, and householders and businesses will have until 14 September to take up the offer or walk away.

“This is a great result and represents an absolutely fantastic saving for people,” said councillor Vaughan Thomas, cabinet member for affordable warmth and energy efficiency at Norwich City Council.

“It will help homeowners and businesses be more environmentally-friendly and save money in the long run. As a council we are really proud to be so closely involved in such an innovative scheme,” he added.
