Hello from a fellow therapist in England,
Yes it is possible to learn Thai Massage in England.
I did quick search and found http://www.thai-massage.org.uk
They ran courses in 2006 in Birmingham. Contact them to see if they are running course for 2008.
Another organisation that run Thai Massage course is The Sunshine Network. If you look at the link below there are details of teachers in England. It does look like most courses are in London. The journey from Birmingham to London is not that long. I am keen to study with teachers from this group. I am thinking of doing some training in Thailand and London.
