Go to the Blacklisted part of this site for the address and write to Experian and Equifax to get a copy of your credit file. It will cost you #2 for each one. If the file shows you are not on the electoral roll, contact your Council and register as this is key to obtaining credit and proves you live where you claim to.(posted 8752 days ago)If your credit file is clear of unpaid debts - you should be OK but mortgages are credit scored so your time in job, time at address, time at bank are all important criteria. You are better applying to a lender here you already have a relationship - a current account or a savings account or a loan for example. They already know you are a good payer.
If your credit file shows debts, use the procedures in the leaflet they send with it to query why.
Hope this helps.
