When you change your name by Deed Poll you agree to abide by three declarations, one of which is to notify all persons concerned of your new name.
This will include your bank, credit card provider, mortgage company etc and they will in turn notify the three main credit reference agencies of your new name.
Therefore your current credit score will not be affected and should you wish you can also contact the credit reference agencies yourself to request that your file is updated with your new name.
The three main credit reference agencies in the UK are: Experian Ltd, Equifax plc and Callcredit plc.
