Deege Solar Arvostelua 

It wasn't all done correctly first time but the fixes were minor, and carried out quickly. It all seems to be performing as promised now and it cost less than the other quotes I got.

When I first ordered the service from this company, everything seemed great. The team was friendly, the service during the installation process was good, and at that stage I had no complaints at all.

However, once the payment was completed, getting anything done became almost impossible. We had to wait around six months for the certificates, which I initially understood since it was winter and delays can happen.

A few months later I noticed that one of the two batteries was not working properly (or possibly not working at all). I contacted them about this and they promised several times that someone would come to inspect and fix the issue. Unfortunately, for the past two months I have been constantly told that someone will come soon, but nobody has actually shown up.

Now it seems they have simply stopped responding and are ignoring my messages completely.

The frustrating part is that the sunny season has already started, which is exactly when the system should be producing the most benefit, but because of this unresolved issue the system is not working as it should.

It is very disappointing, and unfortunately I will probably have to hire another company to diagnose and fix the problem.

This experience really makes me question whether it is worth supporting local businesses if the after-sales service is handled like this.

Over the last four years I’ve been investigating Solar and having lots of different companies come round and try and rip me off with ridiculous prices and not giving me exactly what I wanted Deege Solar was recommended to me by my colleagues Uncle who has been nicknamed the Solar guru!! after speaking to David the owner he came across on the phone as very honest extremely knowledgeable and completely agreed with what I felt I wanted on my roof which was quite Simply wherever the Sun is. I want as many solar panels as possible, apparently that was music to his ears. let me put this into perspective all other companies apart from David could only put six solar panels on my roof apparently.!! I now have 18😁 also David’s price was quite a few thousand pounds cheaper than everyone else’s
After paying the deposit on the phone on trust only within a few weeks things started happening. I run my own business and have worked closely with electricians and roofers all my life and I know if they’re not at the top of their game this was not the case with David’s tradesmen. They were all at the very top of their game and very trustworthy to the point. I actually left my house for a couple of hours unlocked with three people on my property that I’d only known for a day and I was at peace the work and the product they have done and supplied is quite Simply 2nd to none I would highly recommend this company. Don’t bother with anyone else it’s not worth it.

Where to start with this absolute disaster?

My Deege ordeal began in August 2024. Yes, you read that correctly: 2024. Whilst the right make & capacity inverter was installed, it was the wrong model: charging and discharging the batteries at a slower rate than I'd specified. Furthermore, the system pulls about a kWh of energy from the grid every day, even when I'm not at home and peak usage is only around 400W. This occurs regardless of the load placed upon the system or the fact that there is energy available in the batteries to service the load.

Getting Deege Solar to respond is a herculean task. They're happy to pick up the phone when they're waiting for payment, but post installation service is atrocious to non-existent. Their phone lines are never answered and e-mails are blatantly ignored. It was October of 2024 before I could get a-hold of someone. The conversation started well, but things went downhill when we disagreed about the inverter discharge rate, with him ultimately, point-blank, refusing to do anything about it as it would cost him too much money.

I was told it would be a further six weeks before a site visit could be arranged to correct the excessive power draw. I agreed that they could attend the week before Christmas. Things then went very quiet, so I e-mailed them in mid-December to remind them of their obligation: I got no reply. When the day of the site visit arrived, despite waiting in all day, no-body arrived, nobody e-mailed and nobody called. By this time, I was not exactly surprised.

I logged a complaint with HIES, only to learn that Deege had ceased to be a member since 2023, although their website still claimed membership (as a result of my notifying HIES, it no longer does). I've subsequently logged a complaint with MCS, who have referred my case to NAPIT. At this point, Deege did at least come to the table. In light of my experience, I was offered a “system upgrade”: the 6kW Growatt inverter would be replaced by 2 x 3.6kW inverters operating in parallel. This installation was supposed to take place in April 2025, but after their installation team turned-up without any kit, then the wrong kit was delivered, along with numerous other issues, I was left operating on a single 3.6kW inverter for a further three weeks before installation was finally completed in May 2025.

It was around this time that I finally got my handover documentation (inaccurate), MCS certificate & G99 registration, but missed out on 8 months of export revenue.

Problems persisted with the new system (some even getting worse) & Deege continued to ignore me. Proceedings were then escalated to MCS who served Deege Solar with MULTIPLE suspensions of their license, yet still I was ignored by Deege Solar. Eventually, in late 2025 I was contacted as it seemed they’d noticed there was “an outstanding customer complaint” (it’s about the only thing that is outstanding about this company): I imagine it’s hard to issue MCS certificates to your new customers if you’ve had your license suspended. I also wonder if this is not the first time they’ve had such license suspensions, given it took them 7 months to issue my own MCS certificate.

A further “system upgrade” was then agreed & an installation date set. A week before installation, they called to push the date back three weeks, and then failed to attend the new installation date, without any prior notice whatsoever. Via NAPIT & MCS, I’m now claiming a full refund. If they don’t oblige, they’ll be paying solicitors fees and compensation, too.

If you're reading this because you're scouting Deege Solar for potential business, I'd encourage you to go elsewhere. No matter what it is about them that is tempting you, re-read my experience and ask yourself if you want to go through the same thing: is it really worth it?

My story is a very long one which started with another company. But in December 2025 I contacted Deege to help with my Sungrow battery storage system. The fitters turned up beginning of January and replaced the Inverter as I was told by previous company that it was faulty. It turned out it was sabotaged, as company went broke. After Deege fitters left, hoping that all was working, I woke the next morning to find that the batteries had not charged overnight even I was on Octopus Intelligent Go. I am now on Octopus Go as my car (Mii) and wall charger are not compatible (sungrow EV charger box). Spent 4 weeks trying to help get the battery storage up and running. Nothing back from Deege.

Dave from deege solar has been enormously helpful in my quest to upgrade my solar panels and battery storage. His knowledge is second to none, and his prices are the most competitive out there . I would highly recommend
Thanks

We decided to have pv panels on our roof, having had panels in our previous property. Alas, the old FITariffs no longer apply so it isn’t as profitable as it used to be. Degee turned up to install panels on the roof, inverter and battery in September 2022. All done and dusted within a day and a half.
I was a bit apprehensive about using Chinese built equipment as my dealings with Chinese manufacturers in the past have been problematical to say the least.However, writing four years later, I have to say that there have been no glitches or problems with any aspect of the installation Degee was responsible for. The system has worked faultlessly for more than 3 years and I have asked Degee Solar to install another battery to enhance our independance from the usual power suppliers. If the new installation is as good as the last one, I shall be delighted.

This is the second install from Deege, the system was well designed and consisted of 15 solar panels with Tesla powerwall 3, tesla gateway and tesla powerwall 3 expanson unit.

All paperwork given in a handover pack together with the necessary certifications.

The work was done by the deege team themselves and the cables were neat.

Very happy with the install

Deege Solar is recommended, Excellent service with very knowledgeable. The panels were put up very quickly and whole system was in place within a few hours. meanwhil qucik response if any issue happen.
Overall I was very happy with the work and would recommend this company.

I don't usually write a review but I can't believe how negligent this company is.
The system was fitted in 2022 and still they haven't completed the paperwork so we can't get any export tarriff for the solar panels.
We have repeatedly chased them but they just keep kicking it down the road or don't bother to respond at all.
Be very wary!

There are a lot of suppliers in the market. We approached a number, including a big national utility. But Deege were head and shoulders above the others in technical knowledge - meeting customer needs with no hard sell - and delivering with a passion for quality.
Very professional scoping of the system with the flexibility of using optimum equipment / technology to meet our specific requirements and budget.
The full system included:
- 33 Solar Panels and optimisers
- Gateway
-30kw Battery
- EV charger
- Bird protection
Careful installation across two roof areas [with great attention to avoiding damage to roof tiles]. Very thoughtful installation of battery cable runs, gateway and integration into legacy household electrical system.
The team dealt with challenges well and showed a real commitment to delivering a quality, neat and tidy system. They were responsive and reliable.
Personal thank you to Dave for a great design and Jamie and Richie for a quality installation.
Highly recommended for your solar project.

Excellent pre-installation assessment and scoping of work. Good scheduling; PV & battery system deliveries and fit all done smoothly and to a very good quality, despite rather fragile roof tiles. Everything worked well 'straight out the box' and our energy costs are now negative; I estimate payback in 7 years or less, as we are now net energy producers, especially into the 'teatime' gap. And no gas standing-charge.Thank you for making the long trip, Deege 👍

Very helpful and friendly team. There were a few delays on the start date but once the work was underway it was completed efficiently and tidily.
Can't recommend a solar installion enough, one year on i still love watching my panels power the house.
Recommending Deege to my friends and if you go ahead get the biggest batteries you can.

Excellent service with very knowledgeable guys. The panels were put up very quickly and whole system was in place within a few hours.

A few difficulties were encountered but they were really quickly resolved.

The whole company from sales (thank you Pete Ward) to roofers (thank you Richie and your team) to the electrician (thank you Ryan) to customer services (thank you Scott) have been fantastic ...

Have already recommended you

Deege Solar was recommended to us by a neighbour - and were not disappointed. Thus small company’s ethos is professionalism, knowledge and enthusiasm - and the customer benefits from all three. David heads up the team and is ably supported by technicians and support staff. Their success is growing but there is no dilution in their standards - you may just have to wait your turn in the diary. It will be worth the wait. From our limited experience and that of our neighbour, the follow up support is similarly outstanding. Well done.

From the initial consultation to the final installation, my experience with Deege Solar has been nothing short of outstanding.

Pete provided a comprehensive overview of the available systems, offering a competitive quote that made sense for my needs. I opted for the Sigenstor system over the Tesla Powerwall 3, and Pete's technical knowledge and patience in addressing all my questions were invaluable.

Nick handled the battery installation with remarkable attention to detail, ensuring a pristine setup. Despite delays due to M25 traffic, Nick and the team went above and beyond to deliver the equipment promptly. Nick's professionalism and engaging discussions about the technical aspects made the process enjoyable.

Kate was instrumental in coordinating schedules, deliveries, and payments. Her precision and proactive communication kept everything on track.

I also had the pleasure of speaking with David Norman, the Managing Director, whose approachability was commendable. Scott provided consistent updates on the system's progress and offered remote assistance to implement specific requests, showcasing the team's dedication to customer satisfaction.

The solar panel installation was seamless. The installers exceeded expectations, delivering a visually appealing AIKO ABC system that performs exceptionally well. Since the installation of the first set of 15 Aiko Neostar 2S panels, I've been off-grid, and with both sides of the roof now equipped with 30 panels totaling a 13.8kWh peak output, the system's performance is phenomenal.

I wholeheartedly recommend Deege Solar to anyone considering solar energy solutions. Their expertise, professionalism, and commitment to excellence are truly exceptional.

I hired Deege Ltd (Director: David Norman) to install a solar system and refurbish my roof under a settlement agreement, following a prior two-year delay where Deege limited failed to install a solar system despite a deposit being paid. What followed was a nightmare of delays, dangerous work, broken promises, and what appears to be a poor attempt to escape legal responsibility.

Major Issues:

Unsafe Electrical Work: Live wiring was left exposed in the attic, posing a fire and electrocution risk. Earthing cables were left unterminated. Even after being warned by authorities, David Norman ignored professional safety advice from the IET.

Job Incomplete & Severely Overdue: The project is now 200+ days past the agreed deadline (Originally due to be completed on 24July 2024), with incomplete roofing, missing solar equipment (batteries, panels, conduit, incomplete wiring), and no certification or valid sign-off.

Criminal Red Flags:

Negligence: Unsafe scaffolding led to a serious injury in my family.

Trespassing: David Norman accessed and performed unauthorized, unapproved work on a neighbor's property after damaging my neighbors property.

Falsified or missing documentation: Required insurance, certification, and guarantees were never provided, or falsified.

Lied about subcontracting a roofing company to carry out, Roof work they weren't accredited to carry out, including providing false paperwork.

Repeated failure to act on formal notices and safety violations.

Attempt to Evade Responsibility: There is evidence that the director David Norman may be attempting to offload Deege Ltd to a company called Upvolt Ltd — potentially in an effort to dodge liability for the unresolved issues, damages, and breaches of contract. Customers should be extremely cautious.

Broken Promises & Poor Workmanship: Roof work was subcontracted to unqualified workers, resulting in structural defects, water ingress, and visible damage. Many repairs were promised, but never delivered. The director David Norman also demanded payments outside the agreed schedule and failed to pay penalties outlined in our legal agreement.

This has caused deep financial harm, emotional stress, and has left my family living in an unsafe, incomplete home. Deege Ltd's in particular its director David Norman behavior has been dangerous, deceptive, and potentially criminal. I’m sharing this to protect others from enduring the same treatment.

I am currently pursing multiple lawsuits against David Norman & Deege Ltd etc. please do not trust this person as he is a deceptive and fraudulent operator in the industry.

I've had a front row seat to observe his business practice and its disgraceful.

Avoid Deege Ltd (and any successor company like Upvolt Ltd) at all costs.

------------------------------------------------------
Update:

please note that the Accreditations shown on their website i.e. MCS, NAPIT, RECC etc. DO NOT PROVIDE CONSUMER PROTECTION or maintain standards despite their marketing I have direct firsthand experience. Despite the proven violations and criminal behavior mentioned in this review, this company is still certified under these schemes to conduct business. I implore those reading this to pause and take the time to examine this company, their history and the accreditation bodies they belong to before, making the same mistake I did.

This company is facing multiple lawsuits and an ongoing criminal investigation.

Update: This review was originally posted in June 2025. After a significant period with no response from Deege, the company submitted multiple requests for its removal, including claims that the review was related to a different company not Deege Solar and was defamatory. These were independently reviewed by Trustpilot and rejected.

The company’s public reply followed these moderation outcomes. The statements in this review reflect my direct experience and a factual timeline of events: the project was not completed or commissioned; any payment dispute arose after significant delay and incompletion; contractual penalties accrued and remain unpaid; property damage arising during the works remains unresolved and safety issues remain unresolved.

Documentation was submitted which purported to certify works/completion, but did not reflect the actual status of the work done, and the parties carrying out certain works were not those originally represented. Prospective customers are encouraged to carry out their own due diligence.

I was recommended Deege Solar by a friend who had a battery/solar installation locally. I got three quotes including one from a major energy company but I chose Deege Solar for the following reasons. Firstly they were very flexible to accommodate my requirements. For example, I wanted an installation where the battery stack and inverter were in the garage. Their quote included the work to run underground cabling from house to garage whereas the other providers did not offer this. Secondly David took the time to answer my numerous questions up front and gave confidence in their capabilities.

A detailed quote was provided which included ROI calculations. We then agreed an installation date. The scaffolding arrived as planned, and the work was completed 1 day after the planned finish as there was an issue post switch on which the main installer Nick investigated overnight and was fixed the next morning. Scaffolding was removed the week after installation.

The quality of the installation work was very good. The cable runs for the panels, battery stack and inverter were very neat as were the roof panel fitting. Nick answered all my questions throughout the installation process and took me through the app installation setup, explained the system and tested the UPS capability and I have been very happy with the system performance since the installation.

Overall I was very happy with the work and would recommend this company.

The solar system that Deege Solar designed and installed to my specifications was completed today and I am super happy with it! It is a bespoke installation as I wanted certain features and some specific equipment. Deege Solar made it a reality at a price I could afford!
Thank you so much to David and his team and I'm more than happy to recommend Deege if you're looking for a solar installation.

Prolonged incompetence and agony from start to finish. Don't believe the MCS certifications etc or any guarantees. They have no intention of complying.
