I thought I had a gas leak from my cooker, rang Plumbing force who sent out an engineer, Anthony, within 2 hours. He checked my gas main and appliances for leaks and tracked it down to the old cooker. He uninstalled the cooker and checked again for leaks on the whole system. He was extremely thorough, kept me informed of each stage of the work and doubled checked everything. He left us with no mess at all, and helped to move the old cooker out of my way. I would recommend Plumbing force and especially Anthony whom I would suggest should be made engineer of the month !
