@99b9ed46 @0e241662 it is kind of free to incorporate for the vat scheme.
You can pay 10£ and be get it done automatically.

That said, you need an accountant once you are incorporated, and I'd say it is easilly £1,000 per year.

If you don't break 50k to 80k revenue a year, you better loose few tousands pounds in revenue rathen than incorporate than loose that in profit.
