10. Book a table

When you make a dinner reservation using new app and website Charitable, the restaurant donates £1 for every diner to a UK charity – there are 7,000 to choose from. With eateries on Charitable’s books ranging from The Wolseley and Petersham Nurseries to the tiny Honey & Co, country pubs and chains such as Piccolino, Bill’s and Aubaine, this could be the most enjoyable and easy way to do good (charitablebookings.org).
