Today I took the train to reach the center London in the main office (30minutes) and after a 25minutes walk reached there I need to hear that I need to pay a fee of 59£. (Which naturally is not written in the invitation email.) If I am self-employee or make a contract with them the fee is the same. There earn from customer 15£ per hour but pay the cleaners just 8,5£ per hour. You need to calculate the time to reach the house to clean and buy your own stuff for cleaning (hearing from someone). So sometimes even not got time to lunch. And if you no going (sick or family emergencies) you need to pay a penality of 20£-400£.
Totally waste of time! Don't go with them!
If you go there then grap just a free muffin .
