u need to start a firm... and a adress for that firm because its not legal to do it in your yard and make money on it

Do you car washing equipment like they do at car wash places

or do you mean to do it at home with just water and sponges

To be legal you need to create a business, have a business account and register with HMRC as self employed, and be fully insured

where would you be doing this work? whose water would you be using? you probably can't run a business like that from your house

I'm nearly 14, so we were wondering if I could start a buisness up and wash cars for 3 pound per car, maybe more. It would just be round out close but I was just wondering if it would be legal/ would I have to do anything to make it legal

Thanks
