4.7

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.
