The 12 best solar panel installers in the UK 2024

✔ The best solar panel installer with nationwide coverage is Project Solar

✔ We’ve analysed 643 companies to find the best installers in the UK

✔ All these installers are certified by four authorities

If you want to keep the price of solar panels down, you’ll want the installation to be in good hands. After all, a poor installation will only lead to problems further down the line.

But of course, that’s easier said than done. Finding the right solar panel installer for you can be tricky, especially when there are more and more options out there.

Here are some pro-tips from one of the best solar panel installers in the UK, Everyone’s Energy: get quotes from around five different installers, and don’t fall from time-limited deals – they can be a sign that the installer cares more about making a sale than providing you with the best solar panel system to meet your needs.

A good place to start when choosing an installer is looking at their customer reviews on accredited third-party sites. Not everyone has the time or patience to do this however, and it’s easy to become bogged down in the details.

That’s why we’ve done the work for you. Our four researchers spent 30 hours analysing 643 installers across the UK to bring you this definitive list of the best solar panel installers.

These companies come with all the best certificates and highest ratings – because that’s what you deserve.

You can also find the best solar panel installers for your home by using our custom-built comparison tool. Simply fill in this free form, and our trusted specialists will be in touch with quotes.

How did we choose the best solar panel installers?

We began with the view that the best solar panel installers are widely certified and highly rated. Here are the factors we considered, which we’d recommend you think about too.

Accreditations

You deserve a top-quality installer, which means one that’s been assessed and approved by all the major accreditation bodies.

All 643 of the companies we looked into are certified by the Microgeneration Certification Scheme (MCS) – which your installer must be for you to receive payments from government-backed initiatives like the Smart Export Guarantee.

We cut this down to the 77 installers certified by the National Association of Professional Inspectors and Testers (NAPIT), the government-endorsed quality scheme TrustMark, and the Home Insulation and Energy Systems Quality Assured Contractors Scheme (HIES).

Ratings and reviews

It’s crucial to consider how an installer has treated customers who came before you.

The best way to assess this is to research the ratings and reviews they’ve given on independent sites like Trustpilot and Checkatrade.

We’ve measured installers based on their rankings, and we’ve made sure to look at individual reviews to see exactly what customers love (and hate) about each.

We’ve eliminated any company with a ranking under four stars or a low number of reviews, then found the highest-rated installer in each region of the UK.

Experience

Ideally, you want to hire a solar installer with enough experience that they can negotiate any unexpected obstacles with ease.

That’s why we made sure that even when a company on our list is relatively new, its solar panel installers have the necessary experience to provide you with the service you deserve.

Best for nationwide coverage: Project Solar

For more than a decade, Project Solar has installed top-notch solar panels on homes all over the country.

This centrally located company has carried out over 45,000 solar installations, saving a total of 150,000 tonnes of greenhouse gases – and all while sustaining a fantastic rating.

The average solar panel installer is much younger, at seven years old, and has carried out far fewer jobs.

A massive number of customers on TrustPilot have had their say, and Project Solar’s rating is an impressively high 4.4 out of five.

Pros and cons of Project Solar

Customer feedback

“Project Solar UK has been a great company to deal with. The salesman fully explained what we needed and why.

“He then gave us a report on how our system would perform and what it would generate.

“We had a bit of an issue with the installation due to the electrician being sick, but Project Solar got another electrician to complete the install the next day.

“I’ve already recommended the company to family and friends. The app allows you to see exactly what the system is doing.”

Best for East Anglia: CRC Electrical and Renewables

This family-run business is the youngest company on our list, but it contains 10 years’ worth of experience in the renewable energy industry.

And since it arrived on the scene in January 2021, CRC has managed to elicit and maintain a high rating of 4.7 on Facebook reviews, with several happy customers.

We can safely put this down to the company’s trustworthy nature and the genuine care it shows towards its customers in East Anglia.

Pros and cons of CRC Electrical and Renewables

Customer feedback

“Outstanding customer service and attention to detail from quotation through to installation.

“After receiving multiple quotes we took a friend’s recommendation to go with CRC. A seamless installation over 2 days with advice and the offer of ongoing support as we start to learn how to use our new system.

“The panels look great and the electrical work for the battery, inverter etc. is neat and tidy.

“A real team effort from Christian, Liam and their team – thank you again.”

Sarah Oakley, November 2023, Facebook Reviews

Best for London & South East England: Everyone’s Energy UK

In 2020, this London-based company dropped its previous name, GSES Services, for a much more appealing moniker and the slogan “it’s low cost and it’s for you”.

Managing director Jordan Brown has explained that he saw an opportunity to spread the benefits of green energy, saying: “I started Everyone’s Energy with Finn [Rawlings, a director] after seeing the positive feedback from happy customers on their savings.”

Customers have responded with near-perfect ratings – and if you’re worried about solar panel costs, Everyone’s Energy UK has a solution: buy collectively.

The company has partnered with Solar Together, which gets homeowners and local authorities to pitch in for solar panels together, so they can reduce individual costs while sharing the benefits.

Most installers wouldn’t go this far to help its customers – which is why Everyone’s Energy UK more than deserves its spot on this list.

For more information, check out our guide to solar panels in London.

Pros and cons of Everyone’s Energy UK

Customer feedback

“We have been very pleased and impressed by Everyone’s Energy, right from the initial survey, through quotation, installation, commissioning, to final handover and sign off.

“Their communication, customer care, and standard of work has been great.

“Our new solar energy system is performing really well, and we are already seeing the benefits.”

Best for the Midlands: The Eco Roof and Wall Company

As you may suspect, solar panels are just one of the renewable home improvements carried out by The Eco Roof and Wall Company, alongside insulation and heat pump installations.

With two decades of experience behind this Nottingham stalwart, you can rest easy in the knowledge that its staff know exactly what they’re doing.

One of those staff members, Zane Henson, told The Eco Experts that the company’s family-run setup had been crucial to its success.

“With the big corporate companies, the thing you lose is the personal touch,” he explained.

“Being a family-run business, we make sure each job is given due care and attention, from start to finish.”

This level of dedication is rare among installers, and will make the whole process of adding solar panels to your roof much easier.

Pros and cons of The Eco Roof and Wall Company

Customer feedback

“Excellent end to end experience all the way from sales, through to installation and early life support.

“They know what solar products work together well as a system, and also got me through a very difficult period for them through the new year with winter at its peak.”

Kanwar Gill, March 2023, TrustPilot

Best for North East England: 0800 Repair

Let’s be clear: 4.8 is an excellent TrustPilot rating, and even more so when it’s off the back of tens of thousands of Trustpilot reviews.

Many of these reviews come from before PHS Home Solutions launched its 0800 Repair brand, but still, homeowners in the northeast can trust this company.

Its engineers, who have been successfully installing green technology in the area for around 20 years, are continually trained to the newest standards at the company’s in-house academy.

The average solar company doesn’t have a training centre, let alone one where installers can learn from instructors with this much experience.

Pros and cons of 0800 Repair

Customer feedback

“Excellent, very thorough inspection and explained everything in full. Both visits we’ve had have been on time; would recommend highly.”

Mick Rawlinson, February, 2024, TrustPilot

Best for North England: Solar Fast

This Castleford-based installer has maintained a high level of quality since 2006.

The company has achieved its excellent 4.7 rating on Trustpilot with a thoughtful approach that focuses on meeting customers’ specific needs – from the initial design to aftercare.

You can put your faith in Solar Fast, especially as 93% of reviewers have reported having a four or five-star experience.

This is probably because the company uses the best solar panels – which the average company avoids, to cut costs – and values consistency in its installers’ performances.

Pros and cons of Solar Fast

Customer feedback

“From the initial approach on the doorstep to workmen doing the job, all were friendly, helpful and respectful.

“The team were efficient and acted in a professional manner at all times.

“Customer services seem attentive and checked up on each stage of the operation.”

David Burgess, January 2024, TrustPilot

Best for North West England: Warma UK

Warma UK has excellent customer service, and its installers know how to get the job done for a reasonable price – and that’s all reflected by its high rating on Trustpilot.

However, the Cheshire company’s true strength lies in its ability to connect you with solar panel government grants.

If staff can get you some money off your installation, they will – and that’s special. Most installers won’t go the extra mile and do this for you.

Pros and cons of Warma UK

Customer feedback

“Very grateful for the installation of solar panels and storage heaters to my property.

“The process was well explained from application to final EPC survey. Communication from Jack and Alex was good throughout.

“There was a delay in getting the funding, but both kept me updated. As soon as the funding was available, the date was booked in for scaffolding to be put up and the installation booked in (within 2 weeks!).

“All contractors/surveyors who came to my property were friendly and respectful.”

Zoe Whitcombe, January 2024, TrustPilot

Best for Scotland: Greener Energy Group

When you’ve got a high rating of 4.5 on TrustPilot, you’ve done something right.

Greener Energy Group has won plenty of awards for its sterling work in sorting out renewable installations, but its customer reviews are the best argument to pick this excellent provider.

If you move quickly, you may be able to get a free Project EV electric vehicle charger with your solar panel installation – and even if you just get a quote, the company will still plant a tree.

The average installer doesn’t have this much commitment to green causes.

Pros and cons of Greener Energy Group

Customer feedback

“We had solar panels and a storage battery installed in January 2023, and couldn’t be happier with the result.

“Installation was quick and efficient, staff from initial survey through to sign off were unfailingly helpful and informative.

“One year on, the system has worked faultlessly. We wouldn’t hesitate to recommend Greener Energy Group!”

Tom Smith, February 2024, TrustPilot

Best for South England: Solum GB

It’s easy for a family-run business to play it safe, but Solum GB isn’t resting on its laurels.

This long-established south-coast company has earned a 4.9 rating on Checkatrade, with its quote accuracy and workmanship in particular receiving extremely positive reviews.

And it doesn’t stop there, either. Solum GB installs all types of renewable technologies, including excellent solar panels, and attempts to convince its customers to go green for the best reasons.

Its sales line is: “We all decide what type of world we live in. Renewables are part of our future.” We can get behind that level of green enthusiasm.

Pros and cons of Solum GB

Customer feedback

“I recently had a solar PV installation completed on my home, and I couldn’t be happier with the results! From start to finish, this experience has been nothing short of fantastic.

“The installation itself was seamless and efficient. The crew arrived on time and worked diligently to get everything set up. They were respectful of my property and made sure to clean up after themselves, leaving my home just as they found it.

“My monthly electricity costs have significantly decreased.”

October 2023, Checkatrade

Best for South West England: Tile Energy

It’s tough to survive as a sustainable installer for a decade, but Tile Energy has thrived.

The company proudly offers “down-to-earth advice” on renewable installations that puts it above most installers that are unable to properly explain eco-friendly products to homeowners.

Tile Energy follows this up with a level of quote accuracy, courtesy, and reliability that’s earned it a fantastic 4.8 rating on Checkatrade.

It also has a five-star rating on Which? – and as if that wasn’t enough, Tile Energy will give you a 10-year guarantee on your solar panel installation.

Pros and cons of Tile Energy

Customer feedback

“The process of quotation through to installation was very good.

Bad weather delayed the install but the office kept us informed and left us feeling they were doing all they could to resolve and the engineers returned a few days later and completed the work.

“Happy with the job and I would use this company in the future.”

November 2023, Checkatrade

Best for Wales: City Energy Network

City Energy Network offers a holistic approach, which gives you the chance to see all the ways you can save energy and cut your bills before you commit to an installation.

This Cardiff-based company is up-to-date with all the latest sustainable options, as well as all the best government grants, which is exactly what you want from an installer.

And if you doubted its green credentials, City Energy Network has committed to reaching net zero emissions by 2040 – before the UK as a whole.

We welcome this extremely unusual step, and you can take it as confirmation that this company truly values green energy.

Pros and cons of City Energy Network

Customer feedback

“My experience with City Energy was good throughout from the start with the Inspection and then the Survey both of whom went through things with me to ease my mind with regards to the Solar PV Installation.”

Christopher Prior, February 2023, TrustPilot

Best for Yorkshire: Clever Energy Boilers

With 4.2 stars on Trustpilot, Clever Energy Boilers has more than earned its spot on this list.

More than 700 reviews on this site confirm what anyone in and around west Yorkshire knows: you can rely on this company to follow through.

Don’t be fooled by the name, either. The staff are also specialists in renewable installations, and can offer you a range of the best solar panels for your roof.

That’s part of the reason why Clever Energy Boilers has won multiple awards in the local area over the past few years.

Pros and cons of Clever Energy Boilers

Customer feedback

“I had a battery system installed onto my existing solar installation.

“The job was completed to a high standard within the day and the site was left clean and tidy. The engineer installed the various apps on my phone and explained how everything worked.”

Dave, June 2023, TrustPilot
