Annual Service of my boiler
Customer Service
Quality

Hartswood installed my boiler some 6 years ago and I chose them out of 2 other installers because of their professionalism. Each year the engineer arrives on time, is polite introduces themselves, dresses professionally and seems/is trustworthy. So I leave them to get on with the job of checking the boiler and bleeding the radiators. Job done in an efficient way which leaves me feeling reassured. Until the next year

Hartswood Heating serviced the boiler they installed a few years ago. It was done on time and with efficiency by the engineer, Charlie. He discovered the gas pressure to the boiler was low and contacted the necessary agency to come as soon as possible, which they did. The service was completed later in the day to my satisfaction.

Had an emergency while we were away on holiday when a leak was noticed and turned out to be our shower pump. They managed to get an engineer out so quickly to stop the leak and prevent some serious water damage. They got new parts ordered and fitted so efficiently and out our minds at ease while away. 5 star service thank you so much.

We are so thrilled we chose Hartwood for our New gas boiler, replacement radiators & new stainless steel towel rails. We had other quotes, but found Matt really listened to our needs & therefore gave us what we wanted. He was happy to answer all our queries and fine tuning what we eventually decided on. Harry, Jake and Charlie that did the installation were prompt, polite, and respectful. Very clean & tidy work. Highly recommend.

The installation of my heat pump and the associated upgrade to my water pipe and radiators has been great from start to finish. Whether it’s communicating on phone or the engineers in the house, everyone has been great - friendly, polite and tidy. Matt guided me through each step and made sure I understood what I needed and the ASHP itself is a dream - so quiet and efficient. Where things weren’t quite right - a miscommunication about type of radiator wanted - this was dealt with swiftly and without any drama.

This was my first meeting with Matt though I have used Hartswood Hearing one time previously. I had concerns re my boiler having just recently moved into a Victorian Terrace property. I thought the charge for the comprehensive work that Matt did and the time he spent at the property ,which included answering all of my many questions , was more than fair. I found his approach extremely professional throughout and would have no hesitation to use this business again.

Matt's team installed a new scheduling system for our heating and some new radiators. They worked really hard and efficiently, and left everything tidy. Matt recommended a Honeywell evohome system which is easy to set up and seems to be working as expected.

Heat Pump & Heating System Install
Customer Service

I would highly recommend Hartswood Heating. Matt and his team installed a completely new heating system in our four bedroom house including a Vaillant air source heat pump system. Matt and his staff were knowledgable, hard-working and professional throughout. Matt spent a considerable amount of time with us during the initial survey phase discussing how the the heat pump system would work, our options for the size and make of ASHP unit, the heat loss calculations for each room and radiator choices. Work began as scheduled. The team were only delayed due to the discovery of rotten timbers in our bathroom floor. Matt was able to put us in touch with a local builder so that remedial works could take place quickly, so there was barely a pause in the installation. After work was completed we were shown how to control the system in detail. All paperwork and guarantees arrived in my inbox straight after too. Throughout, Hartswood were responsive to our queries and put any minor snags right quickly. We had two other quotes from larger, national companies - one from our own energy supplier whose survey we paid for - but we were less than impressed with their surveys and high-pressure sales tactics.

Matt Lancley undertook an introductory boiler service at our new property. We used Matt as he had installed a boiler at our last property. We were very happy with the results and aftercare service. Additionally, he provided advice for our future plans for heating at the new house. Given our past positive experience of the work carried out, we fully intend to use Hartswood Heating for future work.

Matt from Hartswood Heating repaired our ground-sourced heating system and also made repairs to a bathroom toilet and shower. He made a visit to assess the work, confirmed the appointment date in writing and also let us know when he was 30 minutes from our house on the scheduled day. He and his colleague were polite, respectful, knowledgable and professional. They talked us through the required repairs and completed the work on budget and at a very good price clearing up as they went along and ensuring they did not leave anything other than satisfied customers. I can recommend Hartswood Heating without reservation. It was a relief to find a pluming company with expertise in both heating and general plumbing and their work was excellent.

The old gas boiler here was not compliant with current regulations. Matt is very knowledgeable and went through all of the possible choices to upgrade the heating system. The work in this old house was challenging but the team were friendly and considerate, completed the work on time and cleaned up. I am very pleased with the new boiler and controls so I feel that we made the right decisions. I can thoroughly recommend Matt and his team at Hartswood Heating.

We 100% recommend Matt and the Hartswood Heating team. They have been a pleasure to work with; knowledgable, clear, reliable, conscientious, kind and on hand to clarify any doubts and queries, plus they have gone the extra mile in helping us with some tricky pre-existing electrical issues post installation. The work was completed on time and with absolutely no hidden costs, which we really appreciate! On top of this, their rates are amongst the most competitive for heat pump installation. We wouldn't hesitate to recommend them to anyone looking for a heat pump install and are very grateful to have a warm house in time for Christmas!

First time using Hartswood Heating and most definitely will be using again. Very polite and understood the problem I was having. Identified the issue, and proceeded to rectify the problem. He then proceeded with a service to the boiler. At each stage I was informed of what was needed and if I was happy for them to proceed. I cannot express how pleased I am with Hartswood and will recommend to family and friends. Thank you Matt.

Matt came to investigate why our central heating was not operating although we had hot water. He identified the cause as a faulty thermostat and also noted that the pump had been leaking. He quoted a price for a new pump and thermostat installation which I accepted and advised that the office would advise me when they could send an engineer to carry out the work. He also isolated the wall thermostat so that we had heating until the work could be completed. We received a phone call the following day to confirm a date. The engineer arrived on time on the date specified and carried out the work as agreed. Very impressed with the service and the way the engineer carried out the work efficiently and cleanly. I would recommend Hartswood Heating.

From the first contact to the last, I have to say I’ve been really impressed with Matt and his team, we finally got into the modern ages and had gas central heating installed after 17years of warm air heating. Matt came around to look at the job and was really informative, offering a few different options and being thoughtful as to where the pipe work could go so not to disrupt the house too much and also make it look aesthetically pleasing. Sam was with us most of the week and I have to say how polite and courteous he was and how neat and tidy his work was as well, along with help from John, Charlie and Matt throughout the week, the installation went so well, each day they explained what they would be doing where they would be working in the house and what they had done. We are so happy (and warm now), with the work and looking forward to a nice cosy winter this year. We look forward to working with you again in the future and wont hesitate to recommend you. Thanks again for all your hard work.

I was dealing with Matt who was recommended to me, he was brilliant very quick to reply and keep me up to date and he booked Sean in for my job. I can honestly say he was brilliant as I’ve had different companies provide a boiler service and repairs but they didn’t carry out even half of the checks Sean did! He was so thorough and very polite such a nice guy. I cannot recommend them highly enough super happy and I'm hard to please. Thank you so much feel I'm finally being looked after properly.

We needed a replacement air source heat pump and quickly as we had been without heating for two weeks. Hartswood came to our rescue. Matt came assessed the situation tried to get spare parts and technical information to no avail so we decided to go with a new system. Matt ordered and had delivered within a few days our new heating system. Excellent service all round. We highly recommend Hartswood Heating.
