Your credit score can go up or down as a result of changes to your report.
Staying at the same address for a long time can help you build your credit score because it’s a sign of stability. The longer you’re at the same address, the more trustworthy you’ll appear to lenders.
It's really important to make sure that all of your financial accounts have been updated with your new address, as if they're registered to a previous one, this could be affecting your score.
