Like many I'm sorting out paper work etc and have found household bills going back years! I'm trying to streamline EVERYTHING and finally put my house in tip-top order... well that's my plan! (Still have the cutlery drawer to clear out 
Any tips on what to keep and for how long and even how you store/file things would be much appreciated.
I do have a house file but it's bursting!... and also a concertina file with 6 sections
Thanks in advance
