I contacted Jason when our old boiler needed replacing. He has done work for us before and he is always professional, reliable and efficient. We made an appointment for the following day. He was punctual and courteous, as always. We discussed which brand of boiler would be best and he quoted the cost for supplying and installing the boiler, plus the time-frame involved. Over the next few days, Jason kept us updated on progress with the boiler order/delivery, so we knew what was happening. As soon as he received the boiler, he called us to make an appointment to install it. Jason and his assistant arrived on time, completing the installation within the time frame he'd anticipated. They worked efficiently and with the minimum of fuss and inconvenience. They did an excellent job, finishing in good time, leaving the area around the installation immaculate, making good any loose plaster, thoroughly cleaning surfaces and vacuuming the hallway. They removed all rubbish, including the old boiler. Jason registered the installation with the boiler manufacturer on our behalf and the guarantee arrived with us within a couple of days. As well as being a knowledgeable and reliable professional, Jason is also a lovely, likeable chap. We would definitely recommend him.
