Well my request for British citizenship has been accepted. Just got the letter today. Now waiting for the citizenship ceremony in a few weeks. It has taken seven months in all to get there so not too bad. My advice for what it is worth: -For proof of address, ask the Council Tax Office for a letter stating when you started paying Council tax on your property. Depending on how long you've been at your property, you can go back quite a few years with a single piece of paper. - Ask HMRC for a tax summary, enabling you to easily prove part of (or even all of) your employment history with a single piece of paper. - For the nationality paperwork, I used the Southwark Nationality Checking Service, which I found useful and reassuring. Good luck.
