This will be our 10th year in this house and we still get mail delivered for the previous owners! Not junk mail, catalogues etc but letters from HMRC, the NHS, possibly important stuff. We used to send it on to them, and after telephoning they said they'd sort it out. But after five years it was still coming so we wrote 'no longer at this address return to sender' and popped it back in the postbox. Now we just bin it. Enough is enough. We, and they, had our mail redirected for 12 months and I think we only had 2 items forwarded to us by the people who bought our house.
