No it's not a one off fee they charge this fee every week. £19 per week.
At twelve pound and hour your overpaying em .that is how every agency works im just being honest and telling you where the money is spent.
theres no way of getting rid of agencys , but as i keep saying , the way to do something about the umbrellas and the way they get by AWR is to complain to your MP about them , if people up and down the country did this , it would be a start..
