OVO Solar & Heating Reviews 

Good engagement, quick quote. Followed up by the survey and quick installation .
The quality of the installation, especially by the electrician was brilliant.
Would recommend.

Greenhome, who quoted and then fitted my system were superb from start to finish. The team that came had some serious issues on the morning of install but still came and worked till the job was finished on a very warm day. The team were very professional and a pleasure to have doing the work.

I am very happy with my solar installation. I would recommend most highly this company. Every employee I encountered was very capable and hard working . Each were patient and polite . I was very impressed with their dedication and hard work. I highly recommend this company.

Communication could have been better but excellent installers and the system is working great.

The guys that did the work were friendly and worked really well, everything was explained and everywhere was tidy

Very professional and very well prepared from the scaffolders to installers. Many thanks guys 👍

Very comprehensive quote at the right price with good technical support. Works were uninterrupted back to back days with minimal disruption carried out by experienced staff. I highly recommend them as a Contractor who cares about what they are doing to People's homes.

All good from start to finish, seamless installation, with excellent trades people.

The solar and battery system was commissioned on Friday, 24th April 2026, towards the end of the day. However, only a few hours later, the entire system went completely offline, which was extremely disappointing considering the significant amount of money spent on what was presented as a bespoke system. Unfortunately, despite the sunny weather over that weekend, I was unable to utilise the system for its intended purpose at all.

NextGen arranged for an EcoFlow technician to attend on the following Monday (27/04), and the system was eventually brought back online through factory resetting, rebooting, and further troubleshooting. However, from my perspective as a customer, I remain concerned that there may have been an issue with the wiring or configuration from the outset. I am not a technical expert, but a newly commissioned system should operate smoothly from day one unless something has gone wrong somewhere during the installation or commissioning process.

Although the solar and battery system has now been installed and commissioned, several important issues remain unresolved and require urgent attention. Unfortunately, despite multiple emails, phone calls, and follow-up messages, I have received little to no response regarding the outstanding works.

From day one through to commissioning, I dealt directly with Greg Bishop and Alex McKinney. However, since the final full payment was made, both have stopped responding to my emails and messages, with no call backs or meaningful communication. I feel completely ignored despite several unresolved issues still requiring attention.

The main concerns are as follows:
System Isolation / Gateway Configuration Concern
During connectivity diagnostics, the electrician isolated the entire solar system, including the inverters and batteries. Unexpectedly, this also disconnected the property from the main grid electricity supply. In a properly configured setup, isolating the solar installation should still allow the property to draw power directly from the grid, but this did not happen. This raises serious concerns regarding the configuration, functionality, and operational safety of the system.

Connectivity and Monitoring Issues
The system frequently appears offline, making it difficult to reliably monitor generation and performance data through the mobile application. A Wi-Fi booster was installed in an attempt to resolve the issue; however, the connectivity and stability problems still remain unresolved.

Exposed AC/DC Cabling and Incomplete External Works
Live AC and DC cables have been left exposed without adequate protection or covering. In addition, a garden tile removed during installation has not been reinstated properly, leaving the external area unfinished.

Poor Render Finish Around AC Cabling
The AC cable beneath the rendered finish has not been properly reinforced or secured, resulting in the cable repeatedly protruding through the render, which is both unsightly and concerning from a workmanship perspective.

Missing Spare Ways in Consumer Unit and Gateway
As per the agreed quotation, spare ways were expected to be provided within both the new consumer unit and the Gateway installation. However, I do not believe these have been installed as specified. Despite requesting clarification several times via email, I have received no confirmation or response.

Overall, while the installation itself has been unfinished the lack of aftercare, communication, accountability, and resolution of these outstanding issues has been extremely disappointing. I hope the company takes these concerns seriously and resolves the remaining works promptly and professionally.

Everything went smooth on installation day. Workers were very knowledgeable in their field of work. Would highly recommend them, and the admin team. Thank you.

The whole process of getting the solar system fitted from the initial consultation to the final fit and set up of the SEG was very easy.
Everyone involved was extremely helpful, knowledgeable, friendly and worked very hard to make the whole experience a delight for us and we're very satisfied with the results.
A fantastic team.

All very helpful, well organised and punctual.

I work full time on night shifts so I booked annual leave, hoping that the solar install could take place while I was off. I was very grateful that it did. Roland Hill, the company assigned to us, were very considerate in organising this. The team were all exceptionally professional, courteous and worked to a high standard. We are also delighted with the results.

easy process from start to finish. Whole of workforce from scaffolders to roofers to electricians to survey team were excellent , friendly and efficient. Super impressed.

It was an exceptional service from initial enquiry through to install , there was one small glitch which was rectified immediately
