Green Building Renewables - Daventry Avis 

As self-builders, we decided to use a one-stop shop for all our renewables and feel so lucky we chose Green Building Renewables. Solar and batteries, ASHP and underfloor heating were all calculated based on our specific needs. Matt Cowley from the Daventry branch held our hand throughout the whole project, always available to discuss issues and offer advice and solutions. The team are all friendly, polite and professional. The result is a system which looks great and delivers. We can’t recommend them highly enough.

They are an excellent company 👍came when they said they would and did a great job tided up after themselves Leo - Jordan did an brilliant job with the weather being really bad would have no problem recommending them so thank you to Matt and office staff

Excellent customer service over the phone, by email and in person from the engineer who came out on the call.

Back in November 2023 Green Buildings installed a Tesla Powerwall II and some additional Solar PV panels in my house. They did a great job so when I purchased a PHEV they were at the top of the list for quotations for a charger. Their quote was a bit more expensive than the cheapest quote, but when I discussed the price with them they reduced their price slightly. They did not match the price, but because of the great work that they had done before I decided to accept their new quotation. Now that they have completed the final installation and set up of the Zappi Charger I have a great installation and the MyEnergy App is fully populated and gives a huge amount of information now being connected to the Solar PV and Tesla installations. I am extremely pleased with the final installations and would highly recommend them for any similar installations. They are slightly more expensive than some, but you only get what you pay for. Do not hesitate, include them in your request for a quotation.

I would not recommend Green Building Store. I was looking to purchase a heat pump from them, but they kept recommending unsuitable products which didn’t fit my needs, even though they are recommend installers of the unit which would be suitable and was preferred. When questioned on this I was told they would only fit the unit they would not entertain other conversations.

Sally Hart in particular I found to be unhelpful, rude and condescending, leading me to not using this company.

Over the three years it took for me to get organised and sort out listed building consent, Green Building Renewables were helpful and patient. The installation was smooth and the installation team were lovely. Post-installation support has been wonderful, too. Staff have made themselves available to answer all my questions. Thoroughly recommended.

From start to finish the installation went like clockwork and the whole the team were so friendly and helpful.

The first person I spoke to at Green Business Renewables advised me of the quantity of solar panels and the battery I needed and sent someone to look over the layout of my house. I then received a quotation which I accepted and agreed a start date. The scaffolders arrived a few days before the installation team who worked their socks off. Next came the wiring up and their senior electrician linked it to my router.

He also installed an app on my mobile so I could read the data 24 hours a day – a bonus that I was unexpecting!

I am delighted with the outcome and GBR could not have been more efficient.

Great people to do business with from start to finish - and even during a few hiccoughs with the grid network operator. Couldn't fault the diligence or hard work. We had additional PV panels fitted, an old inverter swapped out and batteries fitted. There was a fair bit of unforeseeable complexity from the existing system (fitted by someone else) but all problems were solved seamlessly. On top of that, the team were all pleasant to have in our house.

From start to finish I found this a highly professional, pro-active, and courteous company to work with: and 'work with' is the key.

I had a very clear idea as a former professional physicist and technologist what I hoped to achieve, which I laid out before GBR as my 'dream', and they then managed this down to a realistic installation that satisfied us both. I had many and technical questions, and challenged assumptions about respective capabilities, and their answers satisfied me that they definitely knew what they were talking about. I also learned a lot from the technological side throughout and had to rethink a few of my own assumptions, usually in a very positive way: discovering things the systems could do that I had not thought about.

Throughout the 2-week installation phase of 14kW ASHP, several larger radiators, high-spec hot water tank, 34 PV panel 14kW array, inverter and 4 batteries, I was delighted with the way they prepared for work, carried it out, and tidied up afterwards. The engineers were particularly helpful in sharing information as I queried particular aspects of the installation, and we had a few occasions where we made joint decisions about a particular challenge that presented itself.

I would particularly commend Ryan for his plumbing and David for his electrical installation skills. Both guys were clearly passionate about their expertise and knowledge of the systems they were installing. They also took a special pride in completing their respective installations not only to a professionally high standard, but also to look aesthetically pleasing, almost like works of art! And, of course, Matt for his helpful management of the whole project from inception to aftercare.

They, and their supporting team - mainly Ollie, Leo, Liam, and a couple of others - were always courteous and willing to help.

The project encountered a few unexpected issues negotiating the construction of the house, as might be expected in a larger-than-average installation such as this. All were successfully resolved, but with a slight understaffing on several days, for various reasons, the project overran by a couple of days. This was a bit frustrating for all of us, but we all kept our cool (at least visibly!) and a few very minor details were resolved by a couple of visits later on without the need for us to be present.

I am very glad it's all over, but delighted we decided to have it done. We are already enjoying the benefits, being completely free of fossil fuel (gas supply capped off entirely), and only using overnight off-peak electricity from a 100% renewable supplier, stored away overnight and used off-grid during the day. But even in November, only 3 weeks off the winter solstice, we are generating up to 15kWh a day on a predominantly sunny one. We look forward to generating much more during spring through autumn and selling back to the grid.

To sum up, I would wholeheartedly commend this particular team of GBR to others reading this, and wish you a very pleasant encounter with a professional, reliable and passionately environmentally conscious organisation.

Excellent service!
Very helpful design and sales staff, friendly and skilled installation personnel; minor teething troubles post commissioning were dealt with promptly.

Excellent service from first contact to final installation of 10 solar panels and Tesla Powerwall battery. Very knowledgeable and competent staff.

Very easy process. Everything was clear from initial assessment to installation. Team in the house were all courteous and tidy. Couldn’t have asked for anything more really.

Very friendly and knowledgable engineer turned up. Had no idea what this service would entail cos never had a heat source system serviced. I was very surprised the whole process only took 30 min but I paid more than 3 times what I used to pay to have my gas boiler serviced in our old house, hence 4 stars rather than 5. I am in the wrong job!

Professional and knowledgeable company, friendly, courteous and tidy staff. Heat pump installation is working well, overall very pleased and would thoroughly recommend.

The entire experience, from the initial site visit to the completed installation was very competent and professional. We had quite a busy installation due to the nature of our roof configuration, but they took it all in their stride and expertly made everything come together.I wouldn’t hesitate in recommending them.

Totally recommended. From start to finish good communication and a great price. Come installation the team were friendly tidy and efficient, really pleased with our solar array and Powerwall.

We were very happy with the service we received from Ryan.

Friendly and tried to fit in with my tight schedule. Serviced my heat pump system. Engineer efficient and helpful.

Green Building Renewables always exceed my expectations. The team are wonderful, really responsive, proactive, and just all round brilliant - couldn't recommend them highly enough.

I have had my solar panel installation for precisely 3 months now and have been delighted with its performance. The Daventry team from inquiry to install were professional, helpful and efficient and did a very neat job on the install.
