Now this one is easy. Too easy, in fact, as London is one of those brilliant cities which is actually chockers with free stuff to do.

One of the most obvious places to start is London’s world-class museums and galleries, which unlike other cities around the world, offer free admission to many of their permanent collections. You could easily spend days wandering the capital’s great galleries without spending a penny. But there’s a chance you could suffer from a serious case of gallery fatigue. Plus there’s loads more to see and do. Here’s a sample itinerary of a full (free) day in London:

11am Free 80 minute yoga class
Dermalogica, Kensington

The Dermalogica store in Kensington hosts a whole line-up of free health and well-being classes and workshops. Check online to see what’s coming up and book in advance.

1pm Take a packed lunch and picnic in the splendour of Kensington Gardens. People-watch, squirrel-watch and bird-watch for free.

2pm. Take in some culture and visit a free gallery or museum. The V&A Museum is nearby and houses an extensive collection of art and design.

4pm Get ready for a big night out with a free makeover at The Body Shop.

6pm. Go to a free taping of a TV show and spend the night with your favourite celebrities. Some of them even give you free booze! Apply well in advance for free tickets at the BBC or at Applause Store. Just keep in mind that you need to queue up very early for tickets on the night, and there’s no guarantee that you’ll get in.

9pm. Time to hit the (free) night clubs! Death Disco in at Notting Hills Arts Club is my pick of the bunch –with guest DJ sets (including the likes of Courtney Love, Tim Burgess, and Mercury Rev) and free live acts as well. (Wednesday nights only)
