You are going to be dealing with a lot of bits of paper. Keeping track of them, keeping copies of every form or letter you send, keeping the originals of any evidence you have from other people – your doctors, your care workers, family and friends – all this will need organising to save time and stress later.
The DWP often looses forms and files. So that’s why you must always keep copies of everything you write, and send only copies of evidence from anyone else. Always, when posting to officialdom, get at least the free postal receipt from the post office. More advice about actually sending stuff here
If you possibly can, buy a printer scanner copier. It will save you spoons, cash and crises in the future. I now fill my own cartridges – it’s really easy, it’s just a question of injecting the right amount of the right colour of ink into the right hole in the cartridge. For detailed instructions google the name of your cartridge plus ‘refill youtube’ and you should find a video to show you how to do it. Inks come from Ebay – or you can just buy ready to use cartridges. I bought my HP one in 2007 – it’s still working fine. Now they cost as little as £25.
