Barclaysafe is (or was!) Barclays' secure paper document storage. I don't have any firm details, but it looks like Barclays are starting (a date of 4 Jan for first letters was mentioned) to write (I haven't had a letter yet) to users of the service to ask them to retrieve pouches/wallets, and the back office is a bit busy with requests (unsurprisingly) so they've not taking any more withdrawal requests at present. Tnere seems to be no date for final closing of the service, it sounds like a phased/gradual thing, letting people get their documents, and also so there's not a deluge all at once on the back office that's shipping all the pouches out.
So if anyone has any recommendations for a similar secure paper document storage service, that would be useful/helpful!
