I'm getting my insurance from a broker (can't remember companys name), but their phone is 01255420564 ask for Damon, tell him you want same as Angel Clean.

They have good prices based on the turnover of your company.
Up to Ł80000 is around Ł900.
That covers public and emloyers liability. No matter how many people work for you.
So its a good choice when you have many employees doing not that many hours.

cheers
