There are a few members based in London. Not sure where they go to surf but if she can get in contact with them ( maybe viva the old app) could rent a car and head to the south coast breaks. There is the London board riders club but not sure how good that is now ( they used to do trips in whoever had a car). There are plans for a Wavepool to be built in London by the same people who run the wave in Bristol but I think that at least a couple of years away.
