Aventus Eco Ltd Reviews

Sean and the team at Aventus Eco provided exceptional support when we needed it most. Our heat pump had been incorrectly installed by another company that has since gone into liquidation, leaving us with nearly three years of no heating, ongoing faults, and constant leaks. Aventus Eco truly saved the day. Sean quickly identified the issues that had caused continuous problems for years and resolved them properly. We finally have warmth in our home again, along with peace of mind and renewed hope. The service has been first class throughout, with excellent ongoing support. I cannot recommend Sean and Aventus Eco highly enough and would like to thank them for their professionalism, expertise, and commitment to doing things right.

Sean and his team went above and beyond…

Sean and his team went above and beyond to try and fix a heat pump badly fitted by someone else. Always prompt and eager to help.

Heat pumps done right

Thank you so much to Sean from Aventus Eco. His heating design, installation and handover have all worked out very well. He is knowledgeable, professional, communicative, and responsive if any issues arise. Going into winter with a couple of cold snaps (-4 degrees), the heat pump has performed brilliantly. During November, the system achieved an impressive energy efficiency (COP) of 4.26. The outdoor unit is silent — I don't know it's on unless I put my hand in front to feel the cold air being pushed out. I was also surprised that the unit looks good aesthetically too. The biggest change has been comfort of my home. This system is a dramatic upgrade from my old gas boiler, which struggled to heat my listed Georgian flat. I sometimes woke up in winter seeing my breath. Combined with some light insulation measures recommended by Loco Home Retrofit, my flat feels completely different. I found Sean through Loco Home Retrofit, who I'd highly recommend as well. If you’re looking for people who combine technical expertise with excellent customer service, go to Loco Home, and go to Sean. And if you're interested in being cosier and doing right by the planet, heat pumps are the way to go.

You would have to look far and wide to find a Company as helpful as Aventus Eco . Sean from Aventus was able to face time my dad and talk him through concerns about how his air source heat pump was performing during cold weather . We managed to resolve the issues with Sean's patient help and expert knowledge. Many thanks again to a genuine guy , would highly recommend.

Outstanding Service from Aventus Eco Ltd – Highly Recommended! I had been struggling with unusually high electricity consumption—around 50 kWh per day—due to my air source heat pump system. Despite reaching out to multiple companies, including the original installer, no one was willing to help or even respond. That’s when I contacted Sean from Aventus Eco Ltd, and I’m so glad I did. Sean promptly visited my home, conducted a thorough evaluation of all relevant factors, and successfully identified the root cause of the issue. He didn’t stop there—he also provided a detailed report that I could share with the installer and even offered to assist further in resolving the problem. Sean’s professionalism, technical expertise, and willingness to go the extra mile truly set him apart. He is an absolute superstar, and I can’t recommend Aventus Eco Ltd highly enough for anyone facing similar challenges.

Exactly as the process should be – right from start to finish Aventus Eco fitted solar panels, battery storage and an air-source heat pump, and the whole experience has been great. There was no hard sell from these guys, just lots of advice from people who clearly care about what they do, their business and their reputation. They took the time to get the design right for my home, including properly working out our power use and heat loss and sizing everything accordingly. The solar panels were a no brainer, but Aventus suggested right sizing the solar panels and adding battery storage. Home energy when the sun’s not shining – brilliant. It’s working flawlessly. The heat pump means I’m no longer dependent on global oil and I’ve cut my carbon footprint. Heat pumps get a lot of bad press, often due to hard-sell companies pushing numbers rather than doing the job properly. The difference here is the care Aventus put in, and the work they have done with Heat Geek and their accreditation process (check their Youtube videos). That was the deciding factor. None of the other companies I spoke to had it. It gave me real confidence everything would be set up properly — and it shows. Originally, I wanted to keep the oil boiler “just in case”. I’m glad I took the leap to ditch it and trust the Aventus design. The house is comfortable and warm throughout. Neat install, great communication, and they made the grant process easy. Aventus Eco combine technical know-how with genuine customer care, and I’d happily recommend them. Thanks. Genuinely.

sean at Aventus Eco upgraded our battery storage and also a service on our heat pump he talked us through the process from start till finish i have Nothing but praise for the company and from Sean I would recommend these guys 100% and use them again in the future.

Great experience using Aventus Eco to install a Heat pump at our terraced home. Very efficient from start to finish from Sean & co, took 4 days and we’re really happy with how it’s working. Sean also took time to talk us through how it all works and has been on hand to answer any question post-installation. Will be recommending them to friends and family.

Aventus Eco upgraded our battery storage quickly and really easily, and fixed problems our original installer had left. Nothing but praise for the company.

Great experience from start to finish, excellent customer service and a job well done !

Outstanding service, difficult decision to make to change to air source heat pump especially give the level of misinformation. Sean/Aventus Eco were outstanding in helping me explore and decide that this was right solution. Additionally it involved full house re-plumb because of problems with the old system, This was handled sensitively and professionally by all the members of the team with Sean setting very high expectations for everyone. I had hesitated because of the level of disruption but in fact it all went very smoothly. Thank you Sean/Aventis Eco and your team. I have no hesitation in fully recommending Sean and Aventus Eco Ltd.

Excellent service before & after installation We've had very attentive customer service from Sean, and are very happy with the outcome of the installation of solar panels & batteries. We are also grateful for his knowledge and input into adjusting our heat pump and currently our bills are massively reduced. Being able to text Sean at any time to ask a question and get a helpful reply within a reasonable amount of time has been a very important aspect to me of the service before and after installation. I would recommend Aventus Eco. Date of experience: May 02, 2025

Sean with Aventus Eco came out and walked us through the entire process of solar panels from start to finish, and we are so chuffed with the results. Sean is a brilliant guy who really is diligent to give you the best service. Not only that, I know if we had any questions in the future he would be here to help us out in a heartbeat. He gives top quality service and wants to make sure you’re 100% happy. You’re definitely in safe hands with Aventus Eco, we would highly recommend!

After calling many companies and having an electrician come and wrongly replace our fit meter Sean could not have been more helpful. He took the time to help, explained everything so well despite it being a small job. He arranged for an electrican to come and checked in afterwards. I couldn't rate him higher, we are very grateful for his help.

Fantastic service from Sean. Extremely knowledgeable about energy efficiency. Customer service has been amazing from start to finish including checking after a few weeks in to make sure everything was perfect. A level of aftercare I haven’t experienced anywhere else.

Aventus Eco installed solar panels and a battery and all went like clockwork. Now running virtually all day on a few £ of off peak electricity (Octopus) and the rest is solar feeding into the battery. Very pleased with the result and the thorough job done by Aventus Eco.

After having several companies provide quotes for solar panels for my husband and me, Aventus ECO was by far the best. Their team was professional, transparent, and most importantly, there was no high-pressure sales pitch at all!

We initially had Sean over to provide a quote, and as we didn’t know much about heat pumps, he explained everything clearly and in a way we could easily understand. He emphasized the importance of proper heat loss calculations for our property, which helped us determine which existing radiators we could keep. Sean also walked us through how the system would operate once installed and shared tips on how to get the best efficiency from it. When the team came to install the system, the entire process was incredibly streamlined and completed in just three days. The guys made sure to cover all our carpets and left the place spotless. I can honestly say Sean and his team were fantastic—our heat pump is now up and running, and even on the coldest days, our energy usage is nearly half compared to gas. Although we’ve needed to tweak a few settings, Sean took the time to show us exactly how to adjust everything. I would highly recommend him and his team to anyone. In fact, we’ve already referred him to our neighbors, and he’s now working on their system too. Thanks again, Sean and team

We had an excellent experience with Sean and his team at Aventus Eco. They recently installed our air source heat pump and hot water system, and Sean was hands-on throughout the entire process. What really stood out was the additional guidance Sean provided about how we could improve our home’s insulation and reduce drafts. He explained how making these simple DIY improvements would help lower the heat loss in our home, ultimately reducing our energy bills in the long run. Sean’s approach was practical and cost-conscious, giving us great tips for upgrades that we could do ourselves to make the system even more efficient. The level of detail and care he put into both the installation and the advice was impressive. It’s clear that Aventus Eco is dedicated to not just installing systems, but making sure they perform at their best for the customer. We couldn’t be happier with the outcome and would definitely recommend Aventus Eco to anyone looking for a reliable, knowledgeable, and customer-focused company.

Aventus Eco is hands down the best company I’ve worked with in a long time. From the first phone call, I knew I was in good hands. Sean took the time to understand my needs and walked me through the entire process, from initial consultation to installation day. What really stood out to me was how well they communicated — I always knew what was happening and when. There were no surprises, and the installation was done ahead of schedule! The heat pump has been running flawlessly, and I’ve already noticed a drop in my energy bills. I highly recommend Sean and his team for their professionalism and efficiency!

On the day of the installation, the team showed up on time and got straight to work. They were professional and efficient, and the whole installation went smoothly.
