swimming lessons for 12 year old

[Ginxi]

Hi I'm trying to find a swimming class for my 12 year old, who is high functioning autistic, and a very capable swimmer, level 5-6; was with Elite Swimming for just over a year, very happy, very expensive!, but they don't seem to be able to accommodate us for the new term within a suitable group (which should ideally be a small group, 2-3 children max).
Any suggestions? Thank you :-)

We love Seals swimming - you could talk to them. They do small groups. www.sealsswimming.co.uk/

I was going to say Elite but then read your post :( but I also noticed the other day that King's Hedges pool are doing new 'premium' lessons with a max ratio of 4 pupils to one teacher.
