There is a lot of Wing Chun in London, and it depends what you are after. Victor Kan, Austin Goh, Sam Kwok, Simon Lau, Kamon, Leung Ting’s WT, probably Boztepe’s EBMAS, and dozens of others.
Some are very marketing oriented, lots of gradings, levels, compuslory seminars and cost.
Some are very formal, with lots of bowing and chinese nomenclature, lots of hierarchy.
Some are great workouts, with lots of calesthenics and warm ups at the start and end.
Some are defensive, some aggressive, some focus on the art, some on real fighting techniques.
Some schools train so you will get minor injuries, cut lips and black eyes. Some will never make contact.
My advice would be to go to as many as possible, observe the class, and see if it is what you feel comfortable with.
Well, since everyone is going to recommend their own school,
if you are interested in the Wong Shun Leung way, I suggest you take the 20 minute Thameslink ride from Kings Cross to St.Albans, where you will find a very informal, friendly school with instructors who each have over 30 years WC experience:

Simple, direct, efficient. No uniforms, gradings, monthly fees, just old school informal in-depth teaching, just like in Hong Kong.
Plus we have a yearly November trip to Hong Kong, where there is nonstop training, sightseeing and partying with the locals for a week! Not to be missed.
Come along, see if it floats your boat.
