Gift aid is tax relief on money donated to UK charities - HMRC
Gift Aid donations made since 6 April 2008, for every £1 donated, the charity can receive 25 pence tax relief from the UK government, so the total value of your £1 donation is £1.25.

Donors must
* pay enough UK income tax and/or capital gains tax themselves to cover the amount of tax the charity will reclaim
* give the charity a gift aid declaration, which should include
- Your name
- House or flat number and post code
- Confirm that your gift is a Gift Aid donation
- Confirm that you have paid UK tax which covers the tax our charity will reclaim.
