Is Ipswich too far?
My husband used East Anglian Sea School, they were very good.
Cannot think of any on the North Norfolk coast. There is the East anglian forum , further down the main topic listings.
might sound strange, but we just came back from Gibraltar - with cheap flights it can be as cheap as doing it in the UK, and its warmer, the water is cleaner and just a great sailing location - we even made it to Morocco, check out theses guys, just brilliant - http://www.atlanticcharters.co.uk/
