If it's expired then all you do is fill in the new passport form,new photo and post it off,i have just done this a month ago,didn't need any member of my family to do anything.
Did you even look on the GOV website before posting, or come straight to GD?
I did mine a few months back. All I had to do was fill in the form, get a terrible picture and send it off with my expired passport.
Once done they send your expired one back with your new one.
One thing I will say if you wear glasses and they have issues with your first set of pictures and ask you to re take them take off your glasses. I had to do three lots before they asked me to remove mine costing me a extra £15 due to being a fiver a pop for passport pictures.
get it signed by someone that has known you for 2+ year
That would be too obvious!
I was going to start a thread for help the other day when I had a small fire in my house
True story, the fire part lol, wasn't really going to post!
I would have happily read such a thread!
-edit for the conceptual lolz of course, not for the house fire, I'm not a pyromaniac sociopath!
It said I had to on the form,I done it anyway and didn't have any problemsYou don't need any of that for a renewal unless your photo is unrecognisable (e.g. you changed genders)
