Being Ltd will make you feel more important. These little boosts are really beneficial when you clean windows for a living.
It is worth remembering that if you go limited and choose to have your vehicle in the business then you may find two issues.As a new limited company, if you decide to lease a vehicle or get finance then you will be applying in the name of the business. If the business doesn't have a credit history (because it's brand new), then you may struggle to get approved for the finance/lease.Also when you come to insure the vehicle, insurance companies can be a bit funny about the owner on the vehicle being different from the driver (because the company owns the vehicle). They may let you transfer your personal no claims bonus into the company but you can't get them back if circumstances change.Its worth considering these aspects before you make the leap.Good luck though with what ever you decide.
