Quick Answer: Which Solar Installers Have the Best Reviews in the UK?
Several UK solar installers have strong customer ratings, including Solar4Good, Sunsave, MakeMyHouseGreen, Project Solar UK and Glow Green Solar. Based on Trustpilot ratings checked in October 2026, most of these companies score around 4.6–4.8 out of 5, although review volumes vary significantly.
The headline rating should not be the only factor you consider. Recent customer feedback shows that even highly rated installers can receive complaints about communication, scaffolding delays, sales pressure or after-sales support.
Before choosing an installer, compare recent positive and negative reviews, MCS certification, warranties, system design, equipment, aftercare and at least three quotations. The best installer for one property may not be the best choice for another.
me electricity demand and suitable roof space, because every kilowatt-hour used directly on site can replace electricity that would otherwise be bought from the grid. Exporting surplus electricity can add revenue, but self-consumption is normally the stronger value driver.
A farm solar project should be sized around actual demand rather than roof area alone. Roof condition, structural loading, three-phase supply, DNO export limits, seasonal demand, battery economics and tax treatment can all affect the result. In 2026, current commercial market guides commonly put mid-sized rooftop installations at roughly £750–£1,100 per kWp, depending on size and complexity. Only a site survey and detailed quotation can establish a reliable price.
What Do Customers Actually Say About UK Solar Installers?
Customer reviews can reveal things that specifications and sales brochures cannot. They can show how installers communicate, whether installation dates are kept, how tidy the work is and, importantly, what happens when something goes wrong afterwards.
The examples below use genuine customer feedback published on Trustpilot. Ratings and review counts were checked in October 2026 and can change over time. Rather than relying only on five-star comments, we have also looked at recurring complaints and lower-rated reviews.
| Solar installer | Trustpilot score | Reviews | What customers commonly mention |
|---|---|---|---|
| Solar4Good | 4.8/5 | 800+ | Detailed surveys, professional installation and helpful staff |
| Sunsave | 4.7/5 | 400+ | Smooth installation, helpful support and competitive packages |
| MakeMyHouseGreen | 4.7/5 | 800+ | Clear advice, low-pressure sales and good communication |
| Project Solar UK | 4.6/5 | 7,000+ | Experienced installers and efficient fitting, with some sales and scheduling complaints |
| Glow Green Solar | 4.6/5 | 1,300+ | Competitive pricing and professional installers, with some communication and aftercare complaints |
| Evergen Solar | 4.2/5 | 1,600+ | Friendly installation teams, but a noticeably higher proportion of complaints about sales and aftercare |
Trustpilot ratings are snapshots rather than guarantees of future service. Review volumes and scores change as new reviews are added.
Solar4Good customer reviews
Solar4Good had a 4.8/5 Trustpilot score from more than 800 reviews, with 92% of reviewers awarding five stars when checked. Trustpilot’s review analysis highlights professional staff, detailed explanations and efficient installations as recurring positives. Some customers, however, report slower responses when arranging technical support or follow-up visits.
One verified customer who had considered several installers said Solar4Good spent around an hour surveying the property and even used a drone before installation. Their conclusion was that:
“The installation was on point.”
The same customer did report delays involving scaffolding, demonstrating why homeowners should look beyond the headline star score when comparing installers.
Sunsave customer reviews
Sunsave had a 4.7/5 Trustpilot rating from more than 400 reviews, with approximately 90% giving the company five stars. Positive feedback frequently concerns customer service, professional installation teams and a straightforward installation process.
One customer who compared different installers described Sunsave as:
“great from quote to install.”
That customer particularly praised the combination of equipment quality, warranty and value. Other reviews describe responsive support when technical problems occur.
However, the feedback is not universally positive. One September 2026 reviewer complained about repeated calls, messages and reminders before a consultation and considered the sales approach too persistent. Trustpilot’s broader review summary also identifies occasional complaints involving certificates, system faults and follow-up administration.
MakeMyHouseGreen customer reviews
MakeMyHouseGreen had a 4.7/5 Trustpilot score from more than 800 reviews. Around 76% of reviews were five-star and a further 13% were four-star when checked.
The absence of aggressive selling appears repeatedly in positive reviews. A verified customer writing in September 2026 said:
“No pressurised sales talks.”
The reviewer also praised the company’s explanations and regular updates during the solar-panel ordering process. Other customers highlight knowledgeable staff, clear system options and professional installation teams.
There are critical reviews too. Complaints include communication difficulties, installation or design issues and dissatisfaction with subcontracted work. This is a useful reminder to establish exactly who will carry out the installation before signing a contract.
Project Solar UK customer reviews
Project Solar UK has one of the largest review histories among specialist UK solar installers. It had a 4.6/5 Trustpilot rating from more than 7,000 customer reviews, including more than 1,400 submitted during the previous 12 months. Around 80% were five-star reviews.
Recent customers frequently praise the installation engineers. One reviewer described their installers as:
“very polite and explained everything.”
Other reviewers mention tidy workmanship, knowledgeable engineers and clear explanations of the finished system.
The critical reviews are important, though. Trustpilot’s review summary identifies complaints about pushy sales representatives, communication and delayed or missing quotations. Individual reviews also report scaffolding delays, changing installation dates and difficulties with post-installation administration.
Glow Green Solar customer reviews
Glow Green’s dedicated solar Trustpilot profile had a 4.6/5 rating from around 1,300 reviews, with 82% awarding five stars. Positive feedback frequently focuses on efficient fitting, clear explanations and professional tradespeople.
One September 2026 customer described the installers as:
“Clean, tidy, methodical and hard working.”
Other verified reviews praise communication from quotation through to installation and describe competitive pricing.
The weaker reviews tend to concern project coordination rather than the solar equipment itself. Recent complaints mention delayed scaffolding, installations taking longer than expected and difficulty getting updates from the company. Another customer liked the completed installation but described the after-sales and complaints process as poor following problems with paperwork and remedial work.
Evergen Solar customer reviews
Evergen Solar had a 4.2/5 Trustpilot score from more than 1,600 reviews. Around 72% were five-star, while approximately 16% were one-star, giving it a more mixed distribution than several of the installers above.
Installation teams attract considerable praise. One recent customer summed up the experience as:
“Friendly engineers. Tidy install.”
Other customers describe installers arriving on time, explaining the monitoring app and completing work efficiently.
Potential customers should also examine the negative feedback carefully. Several recent reviewers complained about lengthy or pressured sales appointments, discrepancies between what they believed had been discussed and the eventual documentation, and after-sales problems. These are customer allegations rather than independently established findings, but the frequency makes sales documentation and written system specifications worth checking carefully before committing.

There is no single installer that will be best for every homeowner. Ratings also change as companies receive new reviews. When comparing solar installers, look at the overall rating, number of reviews, recent feedback and recurring comments about installation quality, communication and after-sales support.
A company with thousands of reviews may give you a broader evidence base than one with a very small number, but review volume alone does not prove that it is the right installer for your property.
Reviews can be useful, but they should form only one part of your research. Check recent positive and negative reviews rather than relying on the headline score.
Look for repeated themes. Several customers reporting the same issue with communication, scaffolding, paperwork or aftercare may be more informative than one unusually positive or negative experience.
Trustpilot, Google reviews and recognised renewable-energy installer directories can all provide useful information.
Check more than one source where possible. This can help you distinguish recurring customer experiences from feedback that appears only on a single platform.
Not necessarily. A high Trustpilot rating is useful evidence of customer satisfaction, but it should not replace technical checks.
Compare the proposed solar panels, inverter, battery, warranties, installation specification and after-sales arrangements. You should also consider how many reviews produced the overall rating.
There is no minimum number that guarantees a good installer. However, a larger body of recent reviews normally provides more information about how consistently a company performs.
For smaller local installers, fewer reviews may be expected. In those cases, ask for references, examples of completed projects and details of relevant certifications and guarantees.
Yes. Negative reviews can be especially useful because they show how a company deals with problems.
Look for recurring complaints involving installation delays, sales pressure, system faults, scaffolding, missing paperwork or poor communication. Also check whether the installer responds constructively and appears to resolve complaints.
Pay particular attention to comments about the property survey, system design, installation quality, communication, punctuality, cleanliness, paperwork and post-installation support.
Reviews describing what happened several months after installation can also be valuable because they may reveal how effectively the installer handles technical faults or warranty issues.
MCS certification is an important check when choosing a UK solar installer. Energy Saving Trust recommends looking for MCS-certified solar installers, and MCS certification may be required if you want to access certain electricity export tariffs.
Always verify the installer directly rather than relying solely on a logo displayed on a website.
Energy Saving Trust recommends obtaining quotations from at least three installers. This makes it easier to compare system designs, equipment, warranties, projected generation and overall price.
Do not automatically select the cheapest quotation. A lower price can represent good value, but only if the proposed specification, workmanship and support are suitable.
A useful quotation should clearly identify the panels, inverter and battery where applicable, together with system capacity, expected generation, warranties and installation costs.
You should also ask how the installer has calculated expected savings and whether roof orientation, shading and your likely electricity consumption have been considered. Energy Saving Trust specifically recommends asking installers about these assumptions.
Neither is automatically better.
Local installers may offer more direct communication and strong knowledge of nearby properties. Larger national companies may have greater installation capacity, established support teams and a larger body of customer reviews. Compare the actual company, quotation and service rather than choosing purely on size.
Repeated complaints about high-pressure selling, unexplained specification changes, poor communication, missed installation dates, unfinished paperwork and difficult after-sales support deserve further investigation.
Energy Saving Trust also advises consumers to be cautious of pressure to sign immediately and large discounts offered only for signing on the spot.
Read reviews written after installation rather than looking only at comments from installation day.
Ask who handles technical faults, what response process applies, whether labour is covered by guarantees and who you contact if the installer-supplied equipment develops a problem.
Yes. Installation quality and equipment quality are separate considerations.
Two installers may quote different panels, inverters or batteries even for similar-sized systems. Compare product warranties, expected performance, manufacturer support and the suitability of each system for your roof.
For more information, see the Getfreequote.co.uk guide to the best solar panels in the UK.
Treat guaranteed-looking savings figures cautiously.
Actual savings depend on factors including solar generation, electricity prices, how much electricity you use while the panels are producing power, export payments and system performance. Energy Saving Trust recommends asking installers which electricity price and self-consumption assumptions they use when calculating savings.
Ask your installer to explain which certificates, warranties, commissioning information and system documentation you will receive.
Energy Saving Trust also recommends that installers provide information about maintenance, inverter fault signals and basic troubleshooting once the installation has been completed.
Look beyond the decimal rating.
Compare recent review patterns, review volume, MCS status, system design, equipment brands, workmanship guarantees, manufacturer warranties, after-sales arrangements, projected generation and total installed cost.
You can also use Getfreequote.co.uk to compare solar panel quotes before deciding which proposal suits your home.
No review rating can guarantee what will happen with an individual installation.
Use reviews as evidence alongside certifications, written quotations, equipment specifications, guarantees and a proper property survey. The strongest decision usually comes from considering all of these factors together.
What the Reviews Tell You
There is no installer whose public feedback is entirely positive. Even companies with ratings above 4.5/5 have customers reporting problems with scaffolding, paperwork, communication or after-sales support.
The more useful question is therefore not simply, “Which solar installer has the highest rating?” Look at what customers say about the parts of the project that could matter years after installation.
Check whether recent reviewers report accurate system designs, reliable installation dates, good communication, complete MCS and DNO paperwork, effective fault resolution and accessible after-sales support. Read recent one-, two- and three-star reviews as well as five-star reviews, and compare several quotations before making a decision.
A large number of reviews provides useful evidence, but it does not replace checking the proposed equipment, warranty terms, installer credentials and the suitability of the system for your particular property.
