Can I put in a plug for Michael Branwell's "Balletic Enjoyment" class at Central School of Ballet on Thursdays from 7.15pm to 8.45pm? It's a bit of hike into central london but I reckon it's worth it. The name is a bit of a misnomer as it's a 'proper' ballet class. Michael is around 60 years old now, but he worked for years as a professional dancer (ENB) and he's studied the history and theory of dance too. Put those together and he has some great tips for improving technique, especially in people who are no longer bendy 15 year olds, and as the class is (usually) quite small, you get quite a lot of personal attention. It's rather a 'gentle' class, but you still work hard - and get results. Classes are drop-in and cost ?8.
