PERMANENT ICE RINKS (ALL YEAR LONG)
Queen's Ice Rink (Queensway): central location, average size, offers private and group lessons. Generally busy in peak hours, open till late. Sessions last 1 hour but no one really checks so you can usually stay longer.
Alexandra Palace: large rink, offers lessons, better skates for hire than most, sessions last 1.5 hs. Not as crowded, but sells out fast and has limited opening hours - from 11 until 16:30 or 17:30 depending on the day.
Lee Valley Ice Centre: Olympic-sized twin pad rink, due to open soon from renovations!!
Streatham Leisure Centre: large rink, offers lessons, sessions are 1 hour, limited spaces so best to book in advance.
Sapphire Ice & Leisure Ice (Romford): super highly recommended by folks!
Guildford Ice: great Ice Dance culture!
Cambridge Ice Arena: in Cambridge, looks big as it's used for ice hockey. Haven't been but considering a day trip to check it out! Update: I've been informed by Nikita that it's smaller than Streatham 🙃
