Within half an hour of posting this job, John Paul May was in touch, we arranged for him to come the following morning at 8.30. He came at exactly 8.30. He talked me through what he was doing and why and proceeded to fix the problem. John Paul is friendly, polite and professional, I am really happy with the job done. I will using be using him again to service the boiler etc and carry out other jobs around the house. I would highly recommend City wide gas services.
