Active Heating and Renewables Ltd is praised across many reviews for heat pump installations, with one reviewer noting a Vaillant system working flawlessly for a year and another reporting a 4.30 SCOP. Reviewers often call the team professional, friendly and knowledgeable, and several say the work was left clean and tidy. Tom is named in several reviews for helpful advice and accurate surveys. One reviewer was unhappy that a paid heat loss survey led to a quote beyond their budget and that the main engineer was hard to reach and slow to progress the work. Another reviewer was left waiting all day when an engineer did not arrive and had to rearrange the service themselves.
When it came time to replace my existing oil boiler I had already decided not to get a heat pump, having read so many negative reviews. However, at the last moment I arranged a survey with Tom from Active Heating & Renewables, expecting this would probably just confirm my fears. By the time the survey was complete Tom had completely won me over to the idea of a heat pump and 6 weeks later the installation work started. It took 4 days to remove the old boiler and oil tank, install a Vaillant heat pump and hot water cylinder, replace 4 radiators and commission the new system. It has now been working flawlessly for the last 12 months, giving us plenty of hot water and keeping the whole house warm throughout the colder months. Everything works just as Tom promised it would, with even greater efficiency than his survey originally suggested. My wife, who was initially highly sceptical of the whole idea of a heat pump and was convinced I was making a huge mistake, now says that it is the single best decision I have made in the last 20 years! I am therefore very grateful to the team at Active Heating & Renewables for designing and installing our new heating system to such a high standard, and for making the whole process as smooth straightforward as possible.
Good first impressions from the company in the search for a heat pump + underfloor heating installation. Only option to get a proper quote was to opt for a heat loss survey (£300+) and ended up being a waste of money as the quote was way beyond initial expectations. While the support team was generally good, the main engineer was very difficult to engage with (I believe he only works part time) so it was painfully slow to get any progress refining the quote or progressing the work. Look elsewhere!
We have used Active Heating for the last few years for any issues, a boiler installation & boiler servicing and they have always been professional, prompt and friendly.
I was initially nervous about installing a heat pump in my terraced house, particularly concerned about the 10mm pipes to radiators and limited space. Active Renewables completely put my mind at ease. From the first consultation, they were incredibly understanding of all my concerns and took the time to walk me through every aspect of the installation process. Their staff were extremely helpful and remarkably fast to respond to all my questions - no matter how technical. The team's knowledge was outstanding. They expertly handled the technical challenges and delivered exceptional results - achieving an impressive 4.30 SCOP while keeping the house consistently at 21°C year-round. I also wanted constant monitoring capabilities, and they went above and beyond to fully install and help me diagnose some initial issues with OpenEnergyMonitor. Professional, knowledgeable, and genuinely committed to customer satisfaction. I couldn't recommend Active Renewables more highly!
Tom & team did a great job installing our air source heat pump. A challenging site with non standard installation, and so far it is performing very well. A slight issue with noise has been rectified by the addition of rubber vibration mounts and the system keeps the house at a good temperature even during the recent cold-snap. Tom has continued to be helpful for advice on fine-tuning the system and optimising performance long after initial installation. Would recommend
New Vaillant heat pump and tank installed. The very accurate pre install survey by Tom means we have exactly the right size heat pump to keep the house warm as economically as possible. Jay and Chris did a great job on the works and they were a pleasure to have around. Recommended.
Installed a 7Kw Air Source Heat Pump system plus some additional radiators into a 4 bed detached property. Professional and thorough service from initial survey to final commissioning. Installers were considerate and friendly. Transparent pricing. Thoroughly recommended!
Fantastic Service - Highly Recommend I couldn't recommend Tom & the Active team any higher. We had an unexpected boiler breakdown, late over the bank holiday weekend... reached out to Active Heating on their website enquiry form & Tom came straight back that evening within 30m to discuss the works. He managed to fit us in on the Tuesday for a replacemnet boiler installation, providing great advice on specification & size (kW) of boiler. His team were great, Tommy arrived promptly at half 8 and worked late to ensure the new boiler installation was all completed properly, including arranging Cadent gas engineer to visit & ensure that the regulator was working correctly for correct supply. We have great peace of mind now with the new boiler & extended warranty. Cannot thank the team enough & would recommend their services to anyone in the area. many thanks Michael
Connor and Tommy came over and did a great job upgrading our very outdated system. They also swapped out our seized inside stop valve for an easier more modern one too which was great. All of the pipework was cut and reconnected out of the way so now we have loads of extra usable space! The guys were friendly, respectful and left their workspace clean and tidy. I will definitely stick with them from now on! Thanks again, Tommy and Connor 😊
I had a great experience with Tom and his team. I was undertaking an extensive renovation of my house with an extension and AHR were helpful firstly in helping me understand how to go about transferring my house to an air source heat pump. They helped me understand the options and then effectively delivered an updated heating system for my 1950s property, including installing the air source heat pump, underfloor heating, water cylinder, water booster, and new pipes and radiators where needed. They worked alongside my builders, who they had not worked with before. My house is now very comfortable and affordable to heat. AHR we're very response to my regular questions and check ins and flexible to my needs. They showed an expert understanding of heat pump systems, I understand they are now regularly installing them. I found ASP via the Heat Geeks website, which I also recommend for anyone considering a heat pump.
Very professional and efficient team. Have already recommended them to several friends and family. Would definitely use them again!
Tom and his team did a great job, professional and knowledgeable. The new boiler is working as it should, I would recommend Active Heating.
Active Heating and Renewables were just brilliant during the installation of a Worcester Bosch hybrid heating system. I can recommend them 100%. Try these guys before you try anyone else. I think you will not be disappointed!
Our central heating was old and no longer heating the house properly. After visiting and carrying out a survey of our property, Tom recommended a new boiler and radiators to replace the old ones. The team from Active installed the new system over the course of a week, and they were brilliant - the work is of the highest standard and the guys went above and beyond, even modifying our kitchen units to make the boiler fit. Once the installation was complete, they showed me how to operate the new boiler clearly and left everything in working order, clean and tidy. We now have central heating that warms the whole house for the first time in years. I will certainly be using Active again in the future.
Couldn’t have wished for a more professional and caring company for our install. Thanks Tom and Team
Tom and the team fitted a new heatpump and solar installation for us after our oil boiler broke down. The team were great and very knowledgeable. Thank you very much definitely recommend to everyone
I highly recommend Active- I contacted them with an urgent issue needing a boiler service and our hot water and heating systems pressure testing for our house sale. They had a knowledgeable and friendly engineer with me quickly to help. They did everything I needed and spent as much time as required to do the job properly without feeling like they were needing to rush off to the next job. Active would definitely be my top plumbing and heating recommendation in the area!
Always a great service thankyou for helping us with the heating
It would have been nice to have phone call to say engineer wasn’t coming, waiting all day, service great at a later date I had to arrange
Have been using Active Heating for over 10 years for all my plumbing and heating requirements. Have always found them to be professional and a reliable company.
