Consumer feedback

Generated from the text of this trader's consumer reviews

Alliance Heating & Air Conditioning, led by Paul (often alongside Lee), comes highly recommended for dependable heating, plumbing and air conditioning work. Customers praise how Paul fits and services boilers with clear explanations, tidy finishes and honest advice—one installer had a Mitsubishi air con fully running on day one during June’s record heat, with both units described as “quiet and efficient.”

What Customers Say

  • Reliability & response times: Many reviewers highlight punctual, “always reliable” visits, including one call for no hot water where Paul arrived the same day and diagnosed a faulty hot water cylinder quickly.
  • Professional, thorough workmanship: Reviews repeatedly mention Paul’s thoroughness—“explained how the new boiler works” clearly, and service work carried out “annually” as part of guarantees.
  • Friendly communication & cleanliness: Customers value being kept informed “all the time,” alongside polite conduct and jobs left “clean and tidy,” with teams like Paul and Lee noted for being respectful of the property.
  • 0 missed appointments in the past 6 months

    "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."
