A free charity-run fundraising website to rival JustGiving, Bmycharity and the anticipated Virgin Money Giving will go live on 1 August.
Mygift.org.uk will have no initial set-up fee or monthly subscription charges for UK-registered charities, and organisations will be able to display logos and messages for free on the site's banner area.
Five per cent of every donation will be taken to cover transaction and credit card costs, a similar proportion to that taken by other such sites.
The new site has been devised by the Charity Service, a registered charity that distributes payroll giving and Gift Aid funds to charities and helps trusts make grants.
Michael Colin, chief executive of the Charity Service, said the site would appeal particularly to small organisations. "Charities with very limited resources will benefit, where previously such a service could have cost them more in administration charges or registration fees than was being raised," he said.
Colin said organisations would be attracted to the site because it was run by a charity and provided choice for people who didn't want to use a commercially oriented site.
"A couple of the other sites have sales people that visit charities, encouraging them to direct their donors onto their fundraising sites," he said. "I wonder if that is the best use of charitable funds.
"We aren't driven by commerce and we are completely transparent," Colin added. "It will see every penny possible returned to where it belongs - the charities."
