same thing with me, no sign of my mortgage at all but I think I may have an idea how that happened. On the online form it asks for Main Forename & Middle name, which I supplied. My mortgage, which is the only debt at my current address, is addressed to me as <Forename> <Middle name> <Surname> and although I had supplied both they decided that wasn't enough and asked me for proof of residence. I duly sent them a bill and for good measure a mortgage statement and they duly sent me back a report without any details relating to my current address.
It isn't particularly clear from their website but when I looked on the report they had only done searches on
<Forename> <Surname> - (which returned some results)
<Middlename> <Surname> - (which returned nothing)
despite the obvious (to me) implications of the word Middle name, they listed no searches on
<Forename> <Middlename> <Surname> at any address
They do have an option to add more forenames, middle names and surnames and I think that the only way to get around their lazy approach may be to add a forename of <Forename><Middlename> and probably any initials as well (e.g. <Forename><M> and <F><M>) as they do not seem to have the same, pretty universal, understanding of "Middle" that the rest of us share.
