Rowenoak Renewables Ltd

Brandon and the team have been amazing throughout our heat pump and heating system installation. We are in a complex listed building with lots of different levels and building materials, poor insulation and high heat loss which made it a very challenging project! Greenwave have been incredibly knowledgeable and supportive throughout our project and we couldn't be happier with our heat pump, traditional style column radiators and underfloor heating. We went four years without any heating system and to have it over this winter has been life changing! Id absolutely recommend Greenwave

I have recently moved into a new development where all of the bungalows / houses have Greenwave Air Source heat pumps installed. During the recent cold spells, my bungalow has remained snug and warm, with no cold spots anywhere. The heat pump runs almost silently and can bearly be heard over the birdsong. The team from Greenwave are helpful and friendly. Thank you. I would not hesitate to recommend Greenwave to anyone with a suitable property for a heat pump

We recently had our new air source heat pump installed by the team at Greenwave Renewables, and we couldn’t be more pleased with the service provided. From start to finish, the team worked to an exceptionally high standard. The installation was carried out with minimal disruption to our home, and great care was taken to avoid unnecessary damage or mess. It was clear that the team takes real pride in their workmanship, as every aspect of the fitting was completed neatly and professionally. They were also extremely knowledgeable and took the time to explain how the system works, answering all of our questions in a clear and helpful way. Their friendly and professional approach made the whole process smooth and stress-free. We would highly recommend Greenwave Renewables to anyone considering an air source heat pump installation.

We had just bought a property and wanted to replace the current LPG system with an air source heat pump before the LPG in the tank ran out, so we didn’t need to enter into a 2-year contract with the LPG supplier and pay any termination or tank removal charges. Therefore, as you can imagine, it was a bit of a race against time, so it was much appreciated that Greenwave acted fast, especially considering this was over the Christmas / new year period! It was just over a month from me contacting them through Checkatrade (23 December) to the heat pump being installed (26-27 January). A week after the first contact, Mark came out to conduct a heat loss survey and put together a proposal and provide a quote. Mark was friendly and down to earth, knowledgeable and happy to answer any questions I had, and tweak the plan to my preferences. The proposal was very comprehensive and informative. The proposal was for installation of a Clivet Edge Evo 2.0 Mono 5.1, four new larger radiators (around ⅓ of our radiators) which needed upgrading due to ASHP’s lower operating temperatures and target temperatures based on the room purpose (i.e., living room vs utility room or W/C), and a larger unvented water cylinder. A week or so later when the office was back open, my installation date was confirmed. The team showed up around 8-9 on the day of installation and got straight to it. Lee, Dan, Luke, Brandon 1, and Brandon 2 (apologies if I’ve missed or got anyone’s names wrong…), were all equally friendly, efficient, respectful of the property, and kept me informed throughout the installation. Work finished around 1:30pm on the second day, and Lee talked me through how to use the system / best practices for system efficiency before heading off. The property was left very tidy for the most part, with only a couple of spots missed which I soon cleaned up afterwards. I was informed on the first day that the Homely smart controller had not been delivered as intended and I am still waiting for this currently (+1 week) but it has been raised internally. This is only a fairly minor thing, that would just allow me to reduce costs slightly by setting schedules around my tariff and have visibility over it in the app. I am able to control the temperature of the rads and water, which is the main thing. As Greenwave are a Clivet-approved installer, you can enjoy a 10-year warranty if the heat pump is installed and serviced by them. Kaitlyn helpfully answered some queries I had about their service plans, and Erin was also helpful keeping me informed throughout the installation and confirming receipt of payment. The house took a long time to heat up initially after installation (not really heating up fully until the next morning) but I don’t believe this to be any fault of Greenwave, and more just of heat pumps being much more effective at maintaining rather than driving a temperature, and it being 4 degrees outside. Sometimes the actual temp will land at +- 1-2 degrees C either side of the target temp that I have set, but again I don't imagine this is any fault of theirs and just a quirk of the heat pump! The heat pump has seemed pretty expensive on the colder days, but we are coming from a much smaller house so I think this would have been a shock regardless - we just didn’t see the cost of the LPG going up on a smart meter (maybe I should put it somewhere less visible…) like we would electric or mains gas, although the % volume gauge was going down pretty quickly! We are in the process of switching to a better-suited tariff, and will also be getting some additional solar panels and a battery (which we will certainly be considering Greenwave for), so hopefully this will improve things quite a bit! Overall, a week on, a happy customer.

I recently had solar panels and batteries installed by Greenwave, and the whole experience has been excellent from start to finish. Every member of the team – from the roofers and scaffolders to the electricians – all were friendly, professional, and clearly took pride in their work. A special mention goes to Struan the surveyor who carried out the initial consultation and the final handover and Kaitlyn in Operations who kept me updated throughout the process. Both were extremely knowledgeable, explained everything clearly, and were a genuine pleasure to deal with. I’m very happy with the installation and the service provided. and wouldn’t hesitate to recommend Greenwave to anyone considering solar.
