I've spoken to them a couple of times recently and they couldn't be more helpful...

Thank you so much Brian.

The Pension Service is part of the Department for Work and Pensions (DWP). I had a 'forecast' from them. I have (of course) lost the letter but go to the GOV.UK and you will find out how to email them.
