Consumer feedback

Generated from the text of this trader's consumer reviews

Alliance Heating & Air Conditioning, led by Paul (often with colleague Lee), consistently earns praise for fast, professional heating and plumbing work. Reviews describe Paul as punctual and reassuring, providing quotes quickly, turning up on time, and completing jobs to a “very high standard,” while leaving homes “clean and tidy.” Customers also highlight excellent communication and value—one review notes the final invoice was “substantially below the original quote” after work finished quicker with fewer parts.

What Customers Say

  • Reliability & speed: Customers liked that Paul could be at the property quickly—“Paul came later that day” to diagnose a hot water issue, and he left after “20 minutes” once the fault was found.
  • High-quality workmanship: Whether installing new boilers, servicing Baxi units annually, or fitting two Mitsubishi air-con systems, work is described as “professional,” “thorough,” and “extremely high standard,” with quiet, efficient results.
  • Clear explanations & trust: Reviewers say Paul “explained how the new boiler works” and offered “ways to keep our gas bill down,” including a detailed, easy-to-understand Gas Safety Report.
  • Clean & courteous service: Customers repeatedly mention tidy finishes and friendly support—“left everything clean and tidy,” with Paul and Lee “very friendly and courteous and someone you can trust.”
  • 0 missed appointments in the past 6 months

    "Paul was brilliant from start to finish I asked for a quote which he gave within a day of visiting my house he agreed a date and turned up on time and completed 5 jobs in my house to an extremely high standard and asked for no cash up front or payment until I was completely delighted with the finished job which I totally was, and I was further pleasantly surprised when the final invoice was substantially below the original quote as Paul completed the work quicker and with fewer parts than estimated. Who expects a tradesman to that these days except Paul from Alliance Heating and Air Conditioning. I’d totally recommend this company and will definitely use them in the future."

    "Cannot say a negative thing about the work Paul and his team did installing 2 new Mitsubishi air con units in our home after our 2 previous over decade old units died. He and his partner did an amazing job getting new air con units installed, including one fully running on day one as we had just had a baby and were in the middle of the hottest days in June on record. Both units have now been installed professionally and our house is lovely and cool. The units are quiet and efficient. Paul worked with our schedule and some difficulties surrounding a party wall. We will not hesitate to call Alliance again for both our yearly service of the air con units but also for our boiler."

    "Paul fitted our Baxi boiler, and as part of the guarantee, it needed to be serviced annually. Paul has done this for years now and we are very pleased every time."
