Under the Inland Revenue's Gift Aid scheme, Cancer Research UK is entitled to reclaim the tax made on gifts by UK taxpayers. This means that, if you are a UK taxpayer, your gift can increase by nearly a third – at no extra cost to you.

For example, if you give £10 to Cancer Research, and you Gift Aid your donation, the Inland Revenue will add £2.80, bringing the total donation to £12.80.

In addition, if you are a higher rate taxpayer, you can reclaim the 18 per cent difference between the higher rate of tax and the basic rate of tax, in your Self Assessment Return.

You can read more about our credit card and the terms and conditions on our credit card page.

Yes, we do. You can purchase gifts and cards from our online catalogue.

All the transactional areas of Cancer Research UK's websites (for example for donating, entering events and buying merchandise) are on a secure server and use industry standard 1024 SSL encryption.

When we capture your personal data it is encrypted in transit, and stored in a carefully controlled environment, with restricted access. We are fully committed to protecting the security of your data. More information on the steps we take to protect your privacy can be found on our privacy page.

We are extremely grateful for all donations we receive, regardless of the amount. We hope you will appreciate our commitment to spending as much as we possibly can on research. Every penny received really does make a difference.

We have taken the decision to only acknowledge individual donations of £10 and over. This is in order to save on administration costs and to ensure that as much of our funds as possible are put into research.

We aim to acknowledge all donations within 14 days of receipt. Sometimes, however, due to a large response to our appeals, backlogs can occur.

During these times, please remain patient with us and we will send your acknowledgement as soon as possible.

If you have not heard from us after three weeks please contact our Supporter Services team on 020 7121 6699 and we will look into this for you.

Cancer Research UK has employed street fundraisers since March 2007. We do not ask for money directly there and then on the street. Our street team collect names and addresses of people wanting to help us beat cancer and then we contact these individuals at a later date in order to find the best way for them to support Cancer Research UK.

If you would like any more information or would like to get involved please contact our Supporter Services Team on 020 7121 6699.
