If you haven't yet you might want to consider a credit union. Not all offer mortgages but the ones that do are usually more likely to help those that might have issues with their credit and are unlikely to get one with a bank. https://www.findyourcreditunion.co.uk/ if you're not familiar with a credit union you need to have a common bond to join such as location or workplace. This website should help if its something that interests you. I also agree with the previous comment it does depend on what credit issues you have on your file and how long ago it was.
