GMR worked hard for me, and got me onto some good sites in London, with some pretty premium building companies. Obviously usual mixed bag of other trades and people on each site, but that's nothing to do with GMR. They have been prompt and straight forward payers without the "special" deductions and schemes other agencies insist you sign up for. Overall would certainly recommend. They got me the job, they took care of the paperwork and paid at the end of each week, what more could you ask for?
