I was one of the lucky people to qualify for this (started my NQT year in 2004). Fast forward to 2011 and this month they've unexpectedly taken over £200 out of my pay. All I can think of is a few months ago I received a letter asking for an updated address, which I phoned and gave them and explained that I had written to them when I changed address about 5 years previous. Everything I know about the SLC makes me worry that this isn't going to go well. Can anyone offer me advice?
