Many reviewers of Earth NRG Ltd describe knowledgeable and helpful staff, with several praising workmanship and tidy installations across heat pumps and air conditioning. A number report clear communication and being kept informed, and some mention that work was completed on time and the site left clean. One reviewer had a poor experience with a heat pump quotation: after paying for a survey, the full calculation and heat-loss report were late, the price rose by about 20%, and calls about the increase were not returned. A separate reviewer says a request for an air conditioning quote was met with a reply about an air-to-water heat pump that ignored the details given.
Contacted EarthNRG for an ASHP quotation earlier this year, I chose them as they are very local to me and also HeatGeek trained and recommend. To be fair, they came pretty quickly, did a survey and I received a price estimate pretty quickly. I had two other companies around as well that did the same thing and EarthNRG was the only one to charge a fee for the survey for which I paid and was very happy to do so. After this is where it all went downhill rapidly, After many weeks of waiting for the full survey and heat-loss calculation that did not arrive, I chased it and received it, but the price was approximately 20% more than the price I had initially been sent over after the survey and also the MCS020 heat-loss was 2 Kw lower than that calculated by the other companies that quoted using the same MCS020 methodology. I had some genuine questions to ask in regard to the unexplained price increase and also the gap in calculated heat-loss compared to the other companies. I am aware that the correct heat-loss calculation is the cornerstone of a good technical design. Get that wrong and you could have a cold house in the middle of winter. Despite messages left on several occasions over many weeks with the receptionist, no one ever called me back, engaged with me to go through the proposal in detail or enter in to any kind of two way discussion. It was such a shame, they seemed like nice guys, I was a genuine customer with cash in the bank and I really wanted to use a local heatgeek trained company, but sadly the complete lack of any call back or engagement from them meant I had no choice but to place my order for a Steibel Eltron ASHP retrofit with another company. I wish them well, but on this occasion I felt genuinely let down and in the end had to face the fact they just didn’t want the job. I was unsure whether to share this feedback as they have a consistently high rating, but this was my experience and it should be shared.
Today we had an Air Conditioning unit installed at our office. We found Ryan & Harvey to be incredibly helpful, knowledgeable & professional when organising our unit. The installers Nigel & Michael also showed great workmanship & professionalism. They left the site clean & took away their rubbish. We plan to recommend Earth nrg to all of our customers.
Great knowledgable installers. Very flexible with the design and my needs. Would highly recommend them to others looking to get a heat pump fitted.
We contacted Earth NRG after a personal recommendation.Their representative Nigel came round and gave us very valuable advice on the options with no pressure. They were honest in terms of time frames and costs. When they arrived they were very friendly and professional in all respects, completed the work in the promised time frames and left the house immaculate. We are thrilled with the finished product and would highly recommend this firm
I had a brand new system installed last September, with brand new ASHP, hot water cylinder and 10x radiators and was introduced to Earth Nrg via Heat Geek. The entire experience from start to finish was fantastic, special thanks to Harvey and George for all their help, nothing was too much and I was kept up to date from the initial contact and survey through to the install and commissioning. A year on and the system is still working great, house is always perfectly warn and most importantly it's both cheap and efficient to run too!
Absolutely fabulous. Nigel was so helpful and knowledgeable. They even fitted on a Sunday so I didn’t have to close my business down for a day. Excellent quality and competitive price, I had a few quotes but this company ended up the best price and I couldn’t imagine any better workmanship. 100% recommend them.
First-class service from start to finish! Nigel came to quote and three weeks later our split air conditioning system is in and operational. His installation was very tidy and he worked well with his electrician (Ant) who also did an excellent job. Our Midea system is fully Home Assistant compatible so we can set schedules and routines with ease. All communications were incredibly quick and professional and we are more than happy to recommend Earth NRG to anyone.
Wasted by time. Emailed with a request for a Aircon quote with full details of what I wanted. reply asking me to submit it via the site with the details I did that and 2 weeks later emails a Air to water heat pump system completely ignoring every detail i asked for. Total waste of my time.
Really can’t recommend this company enough. I had a fault with my heat pump which had been installed 6 years prior by a company who are no longer trading. We tried a few different companies to organise a repair - most of whom never responded or used it as an opportunity to try to upsell. Thank goodness we found Earth Nrg. They responded quickly and attempted a repair. It transpired that this wasn’t possible and so they returned shortly after to install a new unit. At every stage and with every contact I found them to be friendly, professional and knowledgeable. The heat pump now works better than it ever has. I’d never use a different company.
Excellent service with friendly and efficient staff. Thoroughly recommend them
First class company, Joel, Cody and Ryan have been so professional, worked really hard and couldn’t be more polite. Nothing was a problem for them they just got on and sorted everything out accordingly. They always tidied up after themselves and all work is neat and tidy. Would highly recommend to anyone. Great work by all!
We would highly recommend this company to anyone considering having a heat pump installed. Ryan and Harvey are extremely knowledgeable in their field and are very good at assessing the needs of their clients and helped us every step of the way in our limited knowledge. During installation, Ryan, Harvey and their team worked efficiently and considerately to enable the least disruption.
The snow beat them on day one, but day two in they came, clean tidy, respectful. They had first floor flooring to lift and then move the new Heat Pump into position. They never left us without heating or hot water overnight and identified a flow problem which they rectified quickly. The heat pump is now fully installed and automated, loads of hot water, nice warm house and clearly cheaper than gas already.. I had 2 days when the sun popped out I heated the house and paid the over night charge from export. Its running at 350% efficiency, but Ryan sorted the schedules and since then I have fiddled with them to get the heating right around off peak tariffs. Well done Harvey, Ryan, and Cody for getting this all in and keeping us warm.
We have been in contact with these very kind, professional men who managed to sort an RHI problem that no one else was prepared to help with. They spent over an hour with us, and after many phone calls, and only asked for a google review in return. They now have the servicing. Many thanks.
We recently had an air source heat pump installed by Earth NRG ( via Heat Geeks), and we couldn’t be happier with the service. The team was incredibly knowledgeable, courteous, and maintained a clean work environment throughout the installation. They also impressed us by turning up on time, which is always appreciated. Highly recommend Earth NRG for their professionalism and excellent service!
Earth NRG installed a heat pump system in my house. This included removing a kerosine boiler and hot water tank, installing a new Vaillant heat pump and controls, a new Joule unvented cylinder and 4 new radiators. The installers did a cracking good job and I was very impressed with their attitude and the quality of their work. I am impressed with the performance of the system, heating and hot water, it is quiet running and it doesn't wake me up in the morning like my old system did!
Great service from Ryan & Harvey. Work completed to a very high standard, competitive prices and great communication. Would definitely recommend to anyone and very reliable. Many thanks.
Great service, informative feedback,nothing was too much trouble and very competitive prices . I would highly recommend this company. I will definitely be using them in the future.
Harvey and Ryan did a fantastic job of installing our new heat pump. They took care of the BUS [Boiler Upgrade Scheme] application allowing us take advantage of the £7,500 government grant that is available. Minimal fuss, explained everything and left the place spotless afterwards taking all the rubbish away I cannot recommend them highly enough - Top lads!
Prompt, efficient service at a good price, and very helpful with information and tips.
Excellent service :) Really happy with the work done!
Harvey was a really nice gentlemen. Came on call last minute and sorted my underfloor heating on the same day !!!!!!! would use again .
Very friendly and helpful. They installed a Heat Air Pump, new boiler and radiator/pipework through out. I'm very pleased with my heating and the service. Highly recommended!
Earth nrg installed my new air source heat pump which I am thrilled about, the service they gave was brilliant, very professional with a great work ethos and attention to detail. I Would definitely recommend this company! Thank you.
Excellent service from Ryan and the team, extremely knowledgeable and adaptable to modified customer specs - highly recommended!
