Boost your savings with the best solar panels in London from these 5 shops
The Department for Energy Security & Net Zero revealed that the UK now has more than 19 gigawatts (GW) of installed solar capacity. That’s already 4.2 million solar setups if we convert it into typical home systems.
This makes it clear that solar panels aren’t just for eco-enthusiasts or rural homes anymore. They’re becoming a normal part of everyday housing and even commercial properties in our city.
That’s why our team decided to search for the best solar panel installers in London. We looked closely at their expertise, system quality, and pricing.
Here are the companies to check, so you don’t have to sort through dozens of installers on your own.
How much do solar panel services cost in London?
Solar panel installation in London may cost from £4500 to £8000 for a 3 to 4 kW system. The higher the system size is, the more expensive it gets. Other factors that affect the pricing include battery storage and the complexity of installation.
1. The Solar Co.

Address: 21-23 Elmfield Rd, Bromley
Contact Details: +442031938888
Operating Hours: Monday – Sunday: Open 24 Hours
The Solar Co. stood out to us because they cater to both residential and commercial solar panel installations. They cater to spaces ranging from 100 sq ft to 10,000 sq ft, offering customised system designs to maximise energy generation.
Aside from that, they’re also backed by insurance, since they’re members of the Home Insulation & Energy Systems Contractors Scheme (HIES). This is a huge plus as it gives your investment the protection it needs.
Another thing we like about this company is that it also provides solar battery storage solutions. This allows clients to store excess energy for later use and get the most out of their solar systems.
When it comes to their service itself, we can say that they’re very reliable. They have skilled installers who deliver clean solar panel installations. Clients shared that their installers left their property really tidy too.
Just one thing to note: they focus more on installation and aren’t the best choice for solar repair or servicing. They’re not ideal if you have an older system installed by another company and need maintenance or troubleshooting.
Superb installation
“We found the Solar Company to be very response and answered all queries promptly. They were clear and concise in what they were going to do and delivered what they said they were going to do, when they said they were going to it. The installation was superb and they used scaffolding that provided safe access to the roof to install the panels. They were clean and tidy and the installation was straightforward taking care of our house. A local company that were brilliant, efficient and knowledgeable.”
-Mr. Andy Scholes, Google Review
Responsive team
“George was very responsive. Came to see us promptly and provided a very competitive quotation. The work was carried in a timely fashion. All of the installation team were professional, courteous, skilled and friendly. We would highly recommend The Solar Co.”

2. Acen Solar & Electrical Ltd

Address: 44 Broadway
Contact Details: +442030053282
Operating Hours:
- Monday – Friday: 7:30 AM – 5:00 PM
- Saturday: 9:30 AM – 1:30 PM
With 10 years of experience under their belt, Acen Solar & Electrical Ltd is another reliable solar panel provider in London.
We’ve seen their recent projects, and we can say that they install clean-looking panels that blend well with the property’s aesthetics.
With their offerings, both targeting residential and commercial clients, they can personalise solar solutions to a wide range of energy needs and property sizes.
Some of their projects include solar panels and battery storage installation on a 6-bedroom house in Camberwell and a commercial office solar panel installation in Mile End.
It also felt reassuring that they have up to 25 years warranty on their products and a 2-year warranty on their installation service. You get service and equipment protected for the long term.
Also, we appreciate their clear quotes. Clients mentioned that the quotes were itemised in terms of equipment, labour, and scaffolding. This is very helpful for understanding what exactly you’re paying for.
Overall, Acen Solar & Electrical Ltd is a solid choice. We just find their team a bit small, so there might be some wait for installations.
Very helpful team
“Having undertaken a fair bit of research and looking for a local installer I came across Acen Solar. Aras spent much time with me going through a few iterations with my constant questions he was very patient and was always very helpful to draw up proposals, eventually settling on a optimum configuration. He and his team did the install within a week. System is now up and running and exports also setup and I’m definitely seeing a return on my investment.
Highly recommend Acen.”
-Mr. Naveed Bashir, Google Review
Excellent job
“Aras from ACEN installed and commissioned our Solar and Battery system and did an excellent job. His work was neat and precise. I am a retired electrical engineer and found him easy and professional to work with. He was also reliable and flexible with regard to site dates and times. Communication (usually by WhatsApp) was generally good. In our instance ACEN were working for us via Glow Green Ltd, but I understand they undertake work directly. From our experience I would thoroughly recommend them.”

3. Excel Energy

Address: First Floor, 85 Great Portland St
Contact Details: +442038349440
Operating Hours: Monday – Friday: 8:00 AM – 5:00 PM
Excel Energy stood out with its impressive 5-year workmanship warranty. Typically, companies offer only 2 years of coverage, so this extended warranty is a huge advantage and source of reassurance.
Aside from that, their 30 years of experience also give us confidence in their expertise. They’ve already handled solar panel installations with various requirements, so clients can be confident their solar panels will be handled by capable hands.
Their experience shows in their portfolio as well. One installation project we’re impressed with is the QuidelOrtho 1.58 Megawatt commercial solar in South Wales.
It’s a huge project that smaller firms might have a hard time managing, but Excel Energy handled it really well.
We also find their post-install aftercare very reliable. Clients said that the team provided guidance on system monitoring and handled minor issues promptly.
We also love that they offer a free consultation. It’s a great way to get personalised advice and understand costs with no commitment.
The only hitch? They’re more specialised in commercial solar installations, and don’t cater to residential solar.
Professional and efficient
“Exceptional Service from Start to Finish!
I recently completed a solar PV project with Excel Energy, and I can’t recommend them highly enough. From the initial contact to the final delivery and installation, the company was proactive and excelled in every single aspect.
The communication was outstanding—they kept me informed at every stage and were always available to answer my questions. The installation team was professional, efficient, and clearly took pride in their work, ensuring a seamless setup.
Knowing I was in such capable hands made the entire process stress-free. Thank you, Excel Energy, for a fantastic experience and a job truly well done. I look forward to the future with my new system!”
-Mr. Ashwin Shah, Google Review
Smooth and efficient process
“A site visit from Nick Neza left me in no doubt that my solar installation was going to be in good hands with Excel Energy and I wasn’t wrong!
The quote was favourable, the whole process was smooth and efficient. All the various permissions were obtained by Nick, the attention he gave to detail was thorough and so very reassuring. The installation team were simply magnificent. Ploughing on through rain and shine, their work ethic was truely amazing. I could never have imagined the project being completed as it was. Nothing was too much trouble, simply first class!”

4. Sunsave

Address: 119 Wardour St
Contact Details: +442038683236
Operating Hours: Monday – Saturday: 9:00 AM – 6:00 PM
Sunsave won us over with its subscription-style solar financing model. Solar panels in London can be huge investments, so we love that the company gives homeowners a chance to go solar with little to no upfront cost.
In fact, their service Sunsave Plus is the UK’s first solar subscription, which only requires you to pay a fixed monthly rate. It also comes with a 20-year Sunsave Guarantee as a type of protection.
They’re also backed by the government, including the Department for Energy Security & Net Zero. This just proves that their services meet national standards for reliability and quality.
On top of that, we love how accommodating their team is. They’re open to doing video consultations where you can ask questions about their subscriptions and explore your options before deciding.
Clients also shared that their online consultations were promptly scheduled and went really well. They noted clear explanations from the team.
Their installers are also professional, quick, and considerate, topped with great post-installation support.
The only slight downside is that it can be expensive over the long term, especially since costs are spread over many years. Still, we think it’s great for those who want to start going solar immediately and are on a tight budget.
Easy process
“Just finished the install with Sunsave. Very easy process to follow and the support from the team was great throughout. Easily contactable and supportive with any queries.
Highly recommend if you are wanting a manageable solar installation.
Included a last minute request for a EV charger and they were more than helpful getting it added to the quote.”
-Mr. Steve Garroway, Google Review
Honest advice and great service
“Honest advice, great service with fast response times and clear updates. They told me that 3 additional panels on the side of my house would not be worth the investment. Did not try to sell me as many as possible to increase their revenue but only wanted to provide what makes sense for me.
Antonio is always available to answer ta question or provide an update
Would highly recommend”

5. Discover Solar Ltd

Address: The Chocolate Factory, 5 Clarendon Rd
Contact Details: +442036330298
Operating Hours:
- Monday – Friday: 9:00 AM – 6:00 PM
- Saturday: 9:00 AM – 5:00 PM
Discover Solar Ltd offers two free panels with their solar panel plus battery installation. This is a nice added incentive that can help reduce the overall cost of your system.
We also find their solar package options very flexible. They offer systems from 3.68 kW to 7.36 kW, giving you the freedom to choose what best fits your household’s energy needs and budget.
It’s also great that they cater to both residential and commercial solar. Clients looking to switch both their home and business to solar energy will appreciate not having to work with multiple companies.
The quotes are fair too. Clients mentioned that Discover Solar Ltd is the only company that did property checks. They also said that they have the most competitive quotes among other companies.
Their installers? They’re professional and leave a very tidy work. From what we’ve heard, they also explain things very clearly to their clients, especially regarding the app and system monitoring.
However, it’s a relatively new company. While early reviews are great, they’re still on their way to establishing their reliability and reputation.
Incredibly tidy work
“I’m very pleased with the job done by Louis and the fitters. Incredibly professional from start to finish, delivered on every promise, kept to times, incredibly tidy work and a competitive price too. Furthermore the savings so far are more that what was calculated as the estimated saving Louis gave were very conservative. I’m very happy with the work and already seeing the return on the investment.”
-Mr. Sami Mahawish, Google Review
Kind and professional team
“Louis and Discover Solar team are very kind, professional, friendly, efficient and informative. They have done the great job on last Saturday. They are very professional and clean and tidy work. They answered all of my questions explained everything and setup app and systems very quickly. We highly recommend this company and their services. Fantastic work 👏🏻👏🏻👏🏻Thank you for your help and support.”
-Mr. Pirasanthan Nadarajah, Google Review
