The engineer was very nice and knowledgeable. He took the time to talk me through the system in more detail, so that I could understand what features of the system I should look to monitor on a more regular basis.

Viessmann heat pump service
A very thorough annual service was undertaken by EPC as they outlined in their report. The engineer was well versed in the system we have and actually highlighted an issue with the installation where a relief drain was not correctly terminated despite having been originally commissioned by the manufacturer. (Subsequently rectified by Viessmann). Good communication and recommended for their service

Hi Peter,
Thanks so much for taking the time to share such a thorough review — we really appreciate it. It’s great to hear that you were pleased with the level of detail in our annual service and that our engineer’s knowledge of your Viessmann system was evident throughout the visit.
We’re particularly glad that the inspection helped identify that installation issue. Even though it originated from the original commissioning, it’s exactly why a comprehensive service is so valuable — catching those little things before they turn into bigger problems.
Your comments on communication and professionalism mean a lot to us, and we’ll be sure to pass them on to the engineer who carried out your service.
Thanks again for choosing EPC Improvements to maintain your Viessmann heat pump. If you ever need further advice or want to discuss efficiency tweaks for your setup, we’re only a call away.

EPC was recommended to me by a friend… a good experience!
EPC was recommended to me by a friend and neighbour - I also saw his Heat Pump installation and was impressed by the neatness of the work.
My experience has been very good from the very start; a good team explaining their product and their commitment to getting it right! The finished job is neat, tidy and very professionally installed. The plumbing team were polite, friendly and very knowledgeable as was their electrician counterparts. The whole process was properly "Project Managed" by a helpful and knowledgeable person who was always "just a phone call away" - the commissioning engineer carefully explained how to use the system and the associated App.
A great team effort from a committed and friendly company - I thoroughly recommend them.

It was a pleasure working with you, and we’re so glad your friend’s recommendation led you to us. Enjoy your new Vaillant heat pump, and we’ll look forward to seeing you again for next year’s service. And if you’re happy to, please recommend us to friends, family — and even random strangers — who might be thinking about making the switch!
Thanks again for recommending us!

EPC were excellent throughout the…
EPC were excellent throughout the process of investigating our Heat pump right the way through to installation and then an after check to ensure everything was finished and working. I even received a rebate after th grant had been settled.
The process was not straightforward and every step of the way I could phone up and there would be someone to answer questions and they were always supportive.
The installation was thorough and well handled. Equipment and parts arrived when they were needed, no delays and always the correct item.
The work went smoothly and even a tricky installation having to use existing ducts went well without fuss.
Then after the whole system was in and working they turned up again to do an inspection and make sure we were happy with the work, the controls and the app.
Really exceptional work and service.

Hi Martin,
Thank you for sharing such a fantastic review — we’re thrilled to hear how positive your experience was from start to finish. We know heat pump projects can sometimes be complex, so it’s great to hear our team’s communication, organisation, and attention to detail made the process smooth and stress-free for you.
It’s especially rewarding to know that even with the challenges of working with existing ducts, everything came together neatly and on time — and that the follow-up checks gave you confidence in the system and controls. The fact you highlighted our team being “always supportive” really means a lot, as that’s exactly the standard we aim for.
Enjoy the comfort and efficiency of your new system, and we’ll look forward to seeing you again for servicing in the future. And if you’re happy to, please do recommend us!
Thanks again for your kind words.

Top banana
Top banana! From initial engagement to the site delivery team, EPC have been great and I cant fault the quality and communication of all involved. The site was left clean and tidy follow the install of our ASHP, which is so rare to have and everyone involved super friendly and took time to answer any questions we had.

Expert service
The engineer was thorough and clearly knowledgeable. He arrived on time and was attentive to the needs of our home. He wore shoe covers which is always a real kindness that I appreciate - I wish more companies did it. I had a great experience of the service carried out - it was very well done and completed effectively and efficiently. I feel confident in what has been done.
