Advice for filming a surfer

Hi there,
A group of friends and myself are planning a movie in which the main character is a surfer. The actor who is playing the part is not a surfer and has never been surfing before.
I am posting this because I wanted to ask for peoples advice on what he should do to get used to surfing for the film, where I can buy/hire a surfboard for the film, and how would be best to film him while he is on the water. We are based in the UK.
Sorry if I have posted this in the wrong forum, but wasn't sure where it needed to be posted.
Thanks in advance for your help and I can't wait to hear you suggestions.
