There is also Skate Attack in Turnpike Lane, Slick Willies in Kensington may have some ice skates, there is also a rink shop at Guildford and one at Milton Keynes both of which are an easy commute from London. There may be a shop at Lee Valley but not sure, and there is a shop in Chelmsford easily findable on the internet- again an easy journey from London. Rod Turner sharpens every 6 weeks at Guildford and Chelmsford and has a good stock but email in advance as he doesn’t bring with by default. Email address is in the recent sharpening thread.
