Does removing old addresses from credit report help?
Personal identifying information like names and addresses don't affect your credit score in any way, so an old address on your credit report won't have a direct impact on your ability to secure new credit.
How do I find my previous addresses UK?
Your previous addresses will be recorded on your Credit Report, providing your lenders and local councils have shared them with the Credit Reference Agencies. You can use checkmyfile to view your Multi Agency Credit Report, where you'll be able to see your recorded address history.
