This site contains every charity record held by the Charity Commission for England and Wales including removed charities; currently this is over 300,000 records.
The intention of the site is to allow easy donations to charities, using a payment method already used by millions of people in the UK.
There are only a very few charities on this site with a donation link at the moment, but all entries are included for completeness. You can, of course, ignore the pages without donation links if you want. (Search with the word “donate” added to see only those pages with donation links.)
Check out the FAQs.
