I had mine from when I moved in, even with a mortgage. Think if the bank have them you do have to pay an access fee. May be a one off as you should now be able to keep them as electronic records are seen as the prime documents.Ours is late 1890s in a conservation area so they should be quite interesting. I think you can request a copy for something like £10-£15? Might be worth a look.
Some properties don't even have them depending on their age and location.
