When you donate to any charity via a website such as mydonate, or others like JustGiving or Virgin Money Giving say, not all of your money goes to the charity because the website take some administration fees and commission. The websites vary in how much they take, which you can read all about in the Money Saving Expert article here. We chose mydonate as it passed the most on to the charity, in part due to BT's generous sponsorship.
Sadly BT have announced they are closing the mydonate site later this year (read their announcement here), so we have had to look for an alternative. The choices included well established sites such as JustGiving and Virgin Money Giving - which have very large followings, but tend to take more administration fees and commission - or less well established sites with fewer charities using them but often charging lower fees.
In the end, we have decided to go with the Charities Aid Foundation (CAF) which only takes modest fees, is very reputable, and dedicated to supporting charities. For a £10 donation from you, with an extra 25% Gift Aid (+£2.50), a total of £12.05 comes to us (details here).
