Ok, So I am working full time and wish to start up by myself during the evenings and weekends. I understand I will need to register as self employed and that I would need to file yearly tax self assesments.

My question is, will registering as self employed effect my earning from my full time job?

Also for Services that require your employement type (eg car insurrance) would I declare self employed or employed? As my job status as Self employed is not my primary job??

Thanks, Tony.
