Nothing wrong with changing branding bit different to changing your name though eh,it looks dodgy no matter how it looks to you.
I know of about 4-5 builders and they’ve all changed names because they went either bust or took deposits and ran,one guy said I need 20k to finish the last job or I won’t be able to complete yours can I have a larger deposit she agreed,he took the money on the Friday on the Tuesday his company folded,lovely bloke.
As I say I wouldn’t change names but wraps and signage is whatever takes your fancy nothing wrong with changing that,it wouldn’t sit right with me as a customer.
