Latest reviews

  • Nest Thermostat Install (this week)

    Though I didn’t end up completing this job due to scheduling and work travel, Daniel did come for an initial consultation and was very knowledgable and friendly. Would consider hiring him for future work if needed. Good vibes. :))

  • Boiler flame not lighting for central heating

    Daniel was very polite and informative. Very happy with the job done, and to know someone in the local area, whom I will definitely use for future jobs.

  • Correct Heating System

    Daniel came to our house to fix the underfloor heating and did an amazing job. More importantly I was impressed by how knowledgeable Daniel was in his field, he spotted immediately the issue by applying a scientific approach and proposed a smart fix to avoid replacing the system which would have been costly. He's very honest and very professional, I can only highly recommend him and will hire him again without a doubt.
