Boiler service, gas hob safety check and installing Nest thermostat
„Tom arrived promptly and got to work quickly on servicing our boiler and installing our new smart thermostat. He walked me through how to use the thermostat and also completed a gas safety check on our gas hob – a job I hadn’t requested prior to his visit. I would not hesitate to recommend Gas Tech Heating and will be contacting Tom and his team regarding fitting a new radiator at our home later this year! Really great service.”
New combi boiler with additional radiator, all outside pipework, flue in roof, disposal of old
„Very impressed with Gas Tech who transformed my heating system efficiently and neatly. They fitted a new outer discharge downpipe and flue through the roof, sealed off the loft water tank in a very awkward space. Decommissioned the old back boiler which involved moving large wall unit which I could not have emptied and moved on my own. They installed a radiator in the sitting room and finally all pipes were flushed through, All work done with the greatest care. I can recommend them 100%”
Replacement boiler
„Tom and Leo started work on Wednesday 3rd August, to replace my boiler with a combi. Tom and Leo kept us both up to date with the work. Everything went as planned, and the job was complete in 3 days. No problems or issues, and everything was to our satisfaction. Nothing was too much trouble, and both were very professional. Tom tidied up after each day, and I would get a courtesy text of arrival, which is always very handy. Tom was by himself for the last 2 days, and we were very impressed. The price was very reasonable, and affordable. Thank you to Tom and the team, we would recommend.”
