It looks as though they have provided a reconstituted CCA in line with that allowed by Carey v HSBC. This does not require signatures or dates, but must include the correct address when originally provided, together with your name. They must also provide a current version of those T&Cs if different, again with the correct name and address. If they say it is a true copy, then the wording (as well as your name and address) must be absolutely accurate and identical in wording (not layout) to the original. Failure to be identical is fatal.
(They can get the name/address information from any source – it does not have to be gleaned from the original CCA. However, it MUST be accurate. This begs the question, ‘why not just provide the original CCA?’ I think there are two answers: (a) they don’t have it, or (b) it’s cheaper to send a recon rather than dig out the original, as it satisfies a s78 request.)
However, while this complies with a s78 request, it does NOT mean the debt is enforceable in court. The McGuffick ruling also means they can continue chasing, even if they do not have the original agreement.
To enforce this debt in court, they should be forced to produce the ORIGINAL agreement (or a genuine facsimile copy), not a reconstruction. However (and sadly) some judges have fallen for the reconstructed version, as they have not fully understood the Carey ruling, so beware.
In that respect, you are being fobbed off (they may even be, er, fibbing) when they claim this document makes the debt enforceable. It most certainly does not.
