I think it is closer to £84,000 basic. We had a 3% lift in April. I don't think there is any truth in the pay rise being missed if you haven't been signed off, certainly not something I have ever heard.
The sector and duty pay does add up. I put about 5% into the pension and my take one is around £4,600 in the winter and gernally over £5,000 in the summer.
