In order to benefit from a voucher as a resident, you must be part of a group project. As part of this group, you are able to combine the values of your vouchers. There is no minimum size for a group project, but at least half of the total value of the vouchers in the project must be for businesses.
As an example, a group project could consist of 6 residents each claiming a voucher value of £500, and one business claiming a voucher value of £3,000. You can find the full terms and conditions for eligibility for the scheme here.
