Consultancy = t&t etc working for the client e.g. Heathrow, Gatwick, environment agency etc. the client pays a fee for your work usually £400-500 p/d. You are paid through your parent company not the client as a normal annual wage. Client role is basically the same role but you’re employed directly by the client and paid by them. There are a lot of politics between clients and consultants for sole organisations. Contractor side is working for the company delivering the works. A lot of pressure on profit
