AE Renewables ltd is built almost entirely around Erik (also spelled Eric or Erik Johansson), a Heat Geek-affiliated engineer whom Southampton reviewers credit with detailed heat-loss surveys and air source heat pump installations, typically Vaillant aroTHERM units paired with radiator upgrades, unvented cylinders and full conversions from gravity-fed to pressurised systems. His team, including Simon, Mike, Chris and James, are repeatedly praised for tidy, careful work and clear explanations throughout, with one review describing the BUS grant and permissions being project-managed as part of the install. Customers consistently report warmer homes, lower running costs and a smooth, low-risk experience even on older or complex properties. As a heat pump and underfloor heating specialist in Southampton, AE Renewables ltd holds a 4.9-star average from 89 Google reviews.

We picked Heat Geek for their performance guarantee and our Heat Geek was Erik Johansen from AE Renewables Ltd. Erik undertook a detailed heat-loss survey of every room and discussed in detail the various options, making sure we were happy with each design decision. The result was a Vaillant aroTHERM Plus 7kW ASHP running at 45°C design flow temperature coupled to a Joule 300ltr unvented hot water cylinder and a lot of radiator changes to ensure best performance; all with a guaranteed combined heating & DHW efficiency of 390% - we actually got 435% for May. The resulting system is quiet and performing exactly as expected and the house generally feels more comfortable, with the recent May cold snap being a useful initial test. The install team of Erik, Simon, Mike and Chris were excellent. They were friendly, tidy, and proud of their work. They changed the whole house from gravity feed to pressurised, removing all the redundant pipework, shower pump and cold-water tanks. Their communication was excellent throughout, walking us through design options and decisions, and during installation continually checking we were happy with what they were doing. Overall, we are very happy with the whole experience. The combination of a Heat Geek Black Label design with a careful, communicative installer focussed on delivering a quality solution made the whole project feel low-risk. Highly recommended.
Every thing about the installation was very good. The team were efficient, clean and tidy, knowledgeable, courteous and friendly, professional, accommodating to unforeseen circumstances, prompt and thorough.
“Eric came back to service the system he installed for us 12 months ago, and I couldn’t be more impressed. The original install was already very neat and professional, but the level of detail during the service really exceeded my expectations. He carried out a thorough check of all pressures and valves, made sure everything was performing exactly as it should, and even took the time to clean the outside of the heat pump — which looked great afterwards. The amount of dirt and debris that came out of the system was honestly mind-blowing, and it just shows how important a proper service is. Brilliant work from start to finish — highly recommend Eric!”
I recently had a heat pump installed by AE Renewables and couldn’t be happier with the service from start to finish. A big thank you to Eric, Simon, Chris, and Mike – they were all incredibly polite, professional, and a pleasure to have in the house. The team kept us fully informed throughout the entire process, explaining everything clearly and making sure we were comfortable at every stage. They worked efficiently, kept everything very clean and tidy, and the installation itself was completed to an excellent standard. The heat pump installation is amazing, and we’re really pleased with the result. It’s clear they take pride in their work. 5-star service all round – I would highly recommend this team to anyone considering renewable energy solutions!
Erik installed my heat pump 2 years ago and we've been very pleased with the install and the efficiency. House is always warm and our bills have gone down as well. Thank you!!
We had a really smooth installation from Erik and his team. The initial survey was very thorough, Erik explained all the options to us and gave his recommendations supported by the new Heat Geek Zero Disrupt software. This really gave us the confidence we needed to sign up. Erik also took the time for an additional visit before install to make sure everything was in order. Installation was very tidy and stress-free. We knew what would be changing and which bits of the house to prepare in advance. Erik's team were very careful to avoid damaging anything, and they tidied up every day before they went. The wiring, piping and lagging all looks very neat and you can really tell that the team prides themselves in doing good work. No bodging here! System was commissioned on the Friday morning as expected, and Erik explained everything about the app and the software. We are very happy and have been cosy and warm ever since. It's easy to keep track of our running costs and we have been pleasantly surprised at how low they can be (working together with our solar panels and home battery). We would recommend Erik and AE Renewables to anyone for a good heat pump installation!
