We were changing from a gas cooker to an electric one and needed a gas engineer to uninstall the gas cooker safely. Sean was able to fit our job into his schedule with little delay, and the job was very quickly and efficiently done. However, his tests indicated a small gas leak. This proved not to be in the gas line that had fed the cooker at all. It was very impressive to see Sean's diligence and skill as he traced it to a faulty solder joint in the supply to the gas boiler, which he quickly repaired. Overall, it was a job done quickly at a good price, despite having turned out to be much more complicated than could have been anticipated. Communication with Sean regarding all aspects of the job was very easy, and it was a pleasure to have him visit and achieve so much. We would thoroughly recommend him.
