Very friendly and excellent service from Martin Lobjoie who serviced my Heat Pump earlier today. Thank you, Martin!

Multiple members of air source heat pump install team were efficient, hard working, on time and pleasant whilst working in home. Install complete over two days- a well drilled team. Looking forward to finding post install help experience being the same.

thank you im happy with the the work that was carried out and I love the solar panels and a thank you to all the men that carried out the work to install the heating panels this was carried out in 2 days thank you again my house is so warm

A few years ago we needed a new heating system and opted for Greener energy company!They did a great job of changing our system from oil to air source heating and we have been delighted with this system!Every year they come and service the system and this it was done by Martin Lobjoie a highly skilled service engineer who talked us through the working stages of the system and advised us with questions we had on how best to take advantage of the air source way of life! Both my husband and I can,t thank this company enough and also the guys who originally installed the air source heating system not forgetting Martin Lobjoie who did a great service recently!

A very efficient service by Martin Lobjoie yesterday. Having the controls for the Air Source Heat Pump explained once again was very helpful! The house is warm and comfortable. This was so important when my husband was unwell last year.

Martin Lobjoie answered his phone after 5.00 o'clock when I got home to a cold house after a fortnight's absence. Our air source heat pump system had conked out days ago due to power cuts and I was stumped to what to do. I phoned Martin who kindly, patiently and expertly guided me on the phone what to do to get the system going again. Thanks so much!

Excellent annual service on our heat pump. Our engineer, Martin Lobjoie, was incredibly knowledgeable, friendly, and went the extra mile in terms of re-explaining the system and tweaking it for optimum performance. He has visited a few times now and not only remembers us and the property but is able to help us tailor things for our needs.

First class service from all who work at Grenner Energy Group. The employees could not have been more friendly, kind and highly knowledgeable and professional. Work carried out to an exceptional standard and no mess left in property, great banter with the installers and felt very at ease. So glad I chose Greener Energy as my installer. Top job guys, thank you, Arlene Gallacher. Should have added had 12 solar panels and the attic work installed in under a day, next day house surveyed for heat loss for now air heat source pump, new radiators and a towel rail. Work to begin on 25th March, couldn’t be more efficient these guys fab !! Update after next stage Air source heat pump, 8 new radiators and towel rail installed as well as all the water cylinder and others needed in attic in the past 3 days. The lads worked through some pretty wintry weather installing the pump, hard working lads. Nothing was a bother to them, any issues they came across were discussed and solved very knowledgeable. My old gas boiler, water tank and radiators all taken away as was every piece of rubbish, very tidy workers and careful with your property. The office staff are exceptional as well nothing is an issue and they are all so helpful, knowledgeable and professional. Even the accounts department was efficient and reliable, I cannot rate this company highly enough, top quality workmanship.

I DO NOT RECOMMENDED!!!It was a total failure/disaster,the pump started heating properly after 4 months of installation,poor contact to management,hard to get any engineers o fix it,they made a simple mistakes(starting with the wrong measurements of the room's area)....referring to my previous opinion and the greener energy response:due to your inaccurate/wrong calculations of the beginning and the instalation on insufficient number of radiators(after almost 4 months you added two more radiators and changed two to a larger size)Your compensation was to cover our heating in winter time because the pump worked more to reach our temp(19 degrees) because you installed not enough and to small radiators,wchich resulted from an incorrect calculation...I took a several times annual leave to wait for engineers and several times you postponed job on this same day(once ,after my complaint you offered voucher to M&S)system working OK now,after 4 months stress and wasting time on your mistakes..I don't know how your company stayed on the market with that poor service.

It was all fiction, the savings promised never materialised and there has been a significant increase in my energy bills. The salesperson omitted to mention that technology beginning with H does not work with heat pumps, making monitoring difficult. The pump failed in the first month after installation, and various engineers have attended, but there is still a problem. I have been contacting the company since October 2023 about this issue. In January 2024, the company promised to send an engineer to investigate the issue. To date I have not had a response. They installed the pump within the stipulated timeframe, so I gave them a rating.
