Re: OAP
Having rented out my own house, I was staying with a friend temporarily until quitting my job to go travelling. One thing I needed to do was to get some travel injections for various things. I'd been de-registered at the GP surgery I was using whilst living at my now rented house and had long since changed my address to my parents' house about 20-30 minutes away by car. The GP surgery that served the area where I was temporarily staying was only a few minutes away, so I went to register there, only to be told I needed proof of address. I had no tenancy agreement, no bills and no post sent to the friend's house to provide this. I had no utility bills from my parents' place either to register with a doctor near them, of course, so what to do?
Like you, but in my case with The Gimp, I simply changed the address of a recent letter from HMRC sent to my parents' address, printed it out and used it as proof of address for the friend's house. It worked. Job done!
