National Lottery operator Camelot has put forward plans to increase its social investment by a further £1.4bn between 2012-2024, calling for a five-year extension to its current ten-year licence in order to do so.

Camelot will take advantage of the "untapped demand"  in rural areas by installing a further 8,000 lottery terminals in suburban areas throughout the UK if the National Lottery Commission agrees to extend its licence, which is due to run out in 2019.

Since the start of the second lottery period in 2002, Camelot has successfully increased National Lottery sales by 20.4 per cent. To date over £26bn has been raised for the Good Causes programme, which awards grants to individual projects for civic and social regeneration. Some 28 per cent of all National Lottery revenue is expected to go to good causes by March 2012.

Dianne Thompson, Camelot Group CEO, said the ability to expand on this record "hinges on the Commission's assessment of (Camelot Group's) proposal during a relatively small investment window".

"With charities and foundations up and down the country anxious about future funding, an extra £1.4bn in good causes funding alone over the next 12 years could make a real difference to people and communities," she added.

The National Lottery Commission is "carefully evaluating" the proposal, advised its chief executive, Mark Harris.

"We will reach a decision following a thorough consideration of whether the proposal is in the best long-term interests of the National Lottery, and the thousands of good causes all around the country that benefit from National Lottery funding," he said.

Good causes money is distributed by 13 Lottery funders, each independent of government. These include the Big Lottery Fund, Arts Council England, the Heritage Lottery Fund and the Olympic Lottery Distributor.
