We have just had a new air source heat pump installed by our new friends at Cinergi. This pump replaces our old oil boiler so we gain a lot of space where the boiler sat as well as the oil tank in the garden.Dave and colleagues looked after the physical installation and we were very impressed with their attention to detail and consideration during the whole process. The administration team back in the office looked after all processing of the paperwork and government grant application very efficiently as well.If you live anywhere near Romsey and are thinking about a modern clean source of heating for your house I can''t recommend Cinergi too highly. They know what they're talking about with this technology and do the work with the least hassle and disruption to your life. We are delighted with the result.

Cinergi recently installed an air source heat pump at our home. From the surveys conducted by Elliot and Ian to the installation by plumbers Lewis and John and electrician Lewis, the whole job was done efficiently and professionally with no mess or fuss. We couldn't be happier.

We're extremely pleased with our ASHP installation performed by Cinergi, combining it with our pre-existing Solar PV and Solar Thermal systems. In just the first six weeks (Mid February through March) it reduced our average daily energy consumption (kWh) by two thirds, and the cost by one third, all whilst keeping the house very comfortable and providing plenty of hot water.We would really like to express our thanks to Justin who pretty much installed the system single handed! He definitely went beyond the call of duty. He was an absolute pleasure to work with and get to know over the two weeks he was with us. Thank you!

Cinergi are outstanding solar, battery, heat pump and EV charge system designers and installers. Our site was exceptionally challenging in terms of planning constraints, extreme coastal exposure to salty, storm force wind and a complicated and technically demanding roof structure. The system we went with is top end at a brilliant price and is properly installed down to every last detail. We are absolutely delighted. Renewable energy is a no-brainer with great payback, added house value, and is a pleasure to own, as well as the vital carbon thing. Jack, the lead installer's determination and success in getting everything spot on was wonderful. The young apprentices who rotated through the site during the work as part of their training - we'd name you all if we could - were clearly thriving. Shannon, James, thank you for the tireless reworking of our design to get it perfect even as the target you were aiming at shifted about. The Loveridge family are running a jewel of a company doing great things outstandingly well. Their knowledge of heating and electrical systems is deep indeed. If you need a renewables company in the south of England who can cut the mustard on anything from complex domestic systems to commercial scale projects this is who you need to get on site for a chat. I work in the construction sector and know quality and outstanding professionalism when I see it. Cinergi - well done and a huge thank you.

Why aren't people choosing the right company for heat pump?I recently had a heat pump installed, and I couldn't be happier with the entire process. From the initial consultation to the final installation, everything was handled with the utmost professionalism. The team was incredibly knowledgeable, answering all my questions and providing detailed explanations about the system and its benefits. Kate Loveridge was particularly helpful and supportive, explaining each stage of the process and what needed to be done.The installation itself was seamless. The technicians arrived on time, worked efficiently, and left everything clean and tidy. I was particularly impressed with their attention to detail and the care they took to ensure everything was set up perfectly.Since the installation, the heat pump has been performing excellently, providing consistent and energy-efficient heating and cooling. The installed products are Vaillant heat pump and cylinder which is brilliant.Overall, I highly recommend this company to anyone considering a heat pump installation. The combination of expert service, quality products, and excellent customer care made this a top-notch experience!

Cinergi recently replaced the gas combi boiler in our kitchen with a Vaillant Arotherm plus 7kW heat pump and matching Sunamp Thermino 210 DHW unit, and we could not be more pleased with the outcome. Both heating and also hot water supply are better than they have ever been in our mid-thirties ca. 100 square metre 3-bedroom semi-detached house. Our initial contact was a pre-booked visit to Cinergi’s Romsey show room, where we could experience a Vaillant heat pump in action, appreciate the moderate size of a Sunamp Thermino heat battery for DHW, and have an initial, sales pressure-free chat with Ian regarding various potential design options for our property. After a site visit by Ian, the Cinergi team quickly produced an initial quote and heat loss calculations for our specific property. Importantly, Daisy was happy to share her calculations with us so that we could make an informed choice which radiators to keep and which to replace with more efficient bigger ones. Based on those decisions, Katie then sent us a detailed quote and allocated an installation slot within a reasonable timeframe. During the install, Adam and his team were efficient, punctual, tidy and always mindful of our requirements and comfort. As planned, all of the equipment required for heating and DHW (other than the outdoor heat pump unit) is entirely housed in the standard, 600 mm wide kitchen space where the combi boiler had been located. Having now been able to test the new system at temperatures below zero degree C, we can say that it provides comfortable and even heating throughout our home as well as reliable hot water of a constant temperature. In conclusion, we highly recommend Cinergi as heat pump installers, and would be more than happy to share our experience with anyone thinking about making the switch.

Cinergi delivered and installed an EV Charger at our home address. I made the inquiry via their web site and was called within a few hours. After hearing how they would be able to help me I decided to go ahead so we scheduled an installation time for the following week. The office called me when the engineer was enroute and were able to inform me of his arrival time within a 5-minute window.When the engineer arrived, in a clearly marked Cinergi vehicle, he was very courteous and polite and explained exactly what he was going to do and how long it would take. When his job was complete he made sure every area was spotless where he had been working and then demonstrated how to use the charger.From start to finish the service was excellent!

My experience of using Cinergi to install an air source heat pump for me in place of my elderly gas boiler was entirely positive from start to finish. They were very helpful when I phoned them for a chat about whether an air source heat pump would be right for my small mid terraced house. After visiting to do a thorough survey, they sent me an initial quote and I visited their showroom to discuss this with them and see the heat pump they recommended in action which was very useful. Once I decided to go ahead, the whole process ran very smoothly, thanks to Cinergi's organisation and high standard of customer care. I was kept up to date about the installation, provided with all the information I needed, and the Cinergi team were always happy to answer questions. I was impressed with the engineers who installed my air source heat pump so skilfully, and I'm delighted with the final result. I chose to use Cinergi because they were highly recommended to me by a friend whose air source heat pump they installed a few years ago. I second her view. Cinergi provided me with an excellent service and I too highly recommend them.

We were recommended Cinergi by my parents who had a recent air source heat pump and solar battery install. A great family run business who were able to survey and install at a very efficient and effective pace. The install was well explained throughout and I was fully informed. The process from inital quote through to install was brilliant. Thank you.

Cinergi is a solid family run company that puts the customer first. We found them to be friendly, helpful and easy to talk to. Our installation of a ground source heat pump was a smooth and happy experience. We would gladly recommend anyone to this company.

The company is a very well run and organised family business, demonstrated by the ethos emanating from all.From first Web site impression (Everything, well explained), Enquiry, Survey, Tender, Clarifications, Contract, Installation, Commissioning ….. to Handover Documentation, the Team performed exceedingly well and beyond client expectation. For a time, Solar PV project ran in parallel at the same site location as ASHP installation.Onsite personal, always worked well as a team, helping each other in their areas when required (no demarcation issues, no subcontractors, just one company).Communication with the client was always respectful and courteous, taking time to explain any answers to questions that were put their way. Installation wasn’t rushed but well thought through and agreed with client, must give a special thank you to Justin Parry, whom performed exceptionally well throughout the ASHP project. Water is hot and plenty of it too, central heating system is working well and of course will be tested fully this coming winter 😊Good liaison was had with client for Solar PV install, including the battery of which needed further consideration with respect to installation location and its service access panel.Solar Edge, delayed final live commissioning, due to a software update preventing client app monitoring of the system. Cinergi Ltd worked hard to resolve SolarEdge’s problem and kept client informed and updated.Glad to say, the Solar PV system is working very well and can be monitored on the Solar Edge app.Thank you !!! Cinergi Ltd for Outperforming 😊

Cinergi installed in-roof solar panels, 10kW battery, ASHP, hot water cylinder and secondary hot water circuit. The system is all working perfectly and we are thrilled with the outcome.

We knew there was a problem with our Ground Source Heat Pump (no heating for 5 weeks in Feb!) and Dan came and advised us what the problem was and the options available. We took the plunge and went for an Air Source Heat Pump and the difference has been astonishing. The added bonus is that the team who installed it were professional knowledgeable and friendly. Would recommend Cinergi very highly.See more

Installed a Vaillant system boiler and unvented cylinder along with radiators in all rooms.A family business who knew what they doing and worked very fast and efficiently. Tidied up, left no mess and removed all the old rads and boiler. Very personal and friendly. Had to move a couple of things but stuck to their original quote to the penny even though they we very keen on price comparison with others. Can't recommend them enough. Don't be put off with their apparent casual approach they know what they are doing and work very hard. Even came on a Saturday to get things done quicker.See more
