A demonstration by protesters against a drilling firm in clay cross has cost Derbyshire Constabulary nearly £140,000 since it started around four months ago.
Protesters have been camped outside PR Marriott’s, on Pilsley Road, since June. It's understood the company supply the shale gas industry with drilling equipment.
The Derbyshire Police Federation say the cost of policing the protest is having an effect on police budgets.
Inspector Mark Pickard, the federation's chairman said: "The problem is that this eats into the police budgets that are already at a critical stage, and they've got to make savings of £5 million. It looks like fracking is going to move elsewhere on Derbyshire, which we'll have to continue to manage.
"What we have to do is either pay overtime, or take away from normal everyday policing."
There have also been claims that officers have been subject to abuse from protesters.
