If you are a UK taxpayer, using Gift Aid means that for every pound you give, we receive an extra 25p from the Inland Revenue, increasing the value of your donation by 25%, helping your donation to go further at no extra cost to yourself. By ticking the box below you declare that you wish the Griffin Institute to treat qualifying donations made within the last 4 years and in the future until you notify us otherwise with Gift Aid. You are a UK taxpayer and understand that if you pay less Income Tax and/or Capital Gains Tax than the amount of Gift Aid claimed on all your donations in that tax year it is your responsibility to pay any difference.
