    Heatsy completed our boiler repair quickly and efficiently.
    We called at 12pm and were offered two appointments, 4-6pm that evening or 8-10am the following morning at a lower rate.
    … More As it’s winter and mom was visiting from the US we decided to get the emergency appointment.
    The engineer called and text before he arrived and kept me updated throughout the work.
    Coming from the states we’re used to great customer service and I must say Heatsy made me feel right at home.
    Your slogan should be ‘British class with American service’
    I’ll be telling all the other moms at the next PTA meeting 😊

    Great boiler service, the engineer took everything apart and cleaned the inside and changed the seals.
    He also took a water sample from the boiler which showed the system was dirty
    … More and he was able to book me in to get my system cleaned without me needing to do anything.
    Very helpful and professional.
    Thank you
  • Avatar Sarah Luetchford ★★★★★ a month ago
    Was extremely helpful and explained what needed doing and was honest about what I needed to consider. Once he had finished and I messaged with an enquiry my engineer offered to come … More back and have a look. They sent a follow up message to ensure everything was still working and to check it was ok. Would definitely use again.
  • Avatar Martin Gilbert ★★★★ 3 months ago
    I had a combined boiler service with landlords gas safety certificate.
    The company were very professional and my tenant was very happy with the engineer.
    All paperwork and certificates
    … More were emailed in real time and I could track the engineer which is a nice touch.
    Four stars as the appointment had to be rescheduled due to over running work.
