We all assume that Title Deeds are always vital. In fact that is not always necessarily the case.
Land Registry property title is folio only so if you own a relatively old Land Registry property with
1. No Planning issues ( i.e. built before 1963 and never extended)
2. No tax issues - no deaths or gifts on title
3. No marital issues
then title is proved by the copy folio only or, if has issued, the Land Certificate ( a sort of copy folio).
In these circumstances, you don't need and won't have any other title deeds, so no storage issues.
I accept that these would be a minority of cases but its worth just having your solicitor flick through the deeds to see what if anything is necessary and irreplaceable and what could be binned.
