Having just changed my trading name it was very eazy
all my customers had a letter of the change along with new customer detail form , which we have asked them all to fill in , I now have all but a few contact details of all my customers ,
Just remember you will have to change your bank account to your new trading name along with all your paper work busisess cards , insurance , inland revenue if you employ , its a lot to do just for a change in name
But this has given me the new start i have wanted for quite a while , I now feel i can move forward with my business
hope this helps
