Thanks for the reply.
On my credit file, the status is marked as Settled, although this is then detailed below as partially settled. I could be wrong due to my lack of knowledge but would the fact that it is marked as 3 months in arrears add to the issue? The 3 months in arrears is quite annoying as there was not a monthly payment required, and I have never missed a payment on any account.
I am aiming to apply for a mortgage before the end of the year but as my file sits at the minute I believe it would be extremely unlikely I will pass until July 2017 when this removes.
Again, thanks
EDIT: On credit file the sections for date last delinquent and default date is blank so I am assuming it is not defaulted?
