The 5 Best Solar Panel Providers in London That’ll Make Your Roof Work Overtime
When my cousin moved into her new London place, she wanted to make it energy-efficient from the start.
That goal became a lot more urgent after her first electric bill arrived, because it made her realise just how expensive it could be to run the house the usual way.
Solar panels seemed like the obvious next step, but the research was overwhelming. Every company sounded like it had the “best” system, and the jargon did not help. One firm even asked about her roof’s “solar yield potential”—whatever that means!
My cousin knew what she wanted, but figuring out where to begin felt like hacking through a jungle with a spoon. Since I owed her for helping me assemble Ikea furniture, I took it upon myself to find the best solar panel providers in London.
If you’re ready to cut bills and your carbon footprint but don’t know where to start, this guide is for you.
How much does solar panel installation cost in London?
Solar panel installation in London typically costs £6,000–£8,100 for a 2–3 bedroom home. Adding battery storage increases the price, which can reach £14,000 depending on system specifications.
1. The Solar Co.
Address: Kingfisher House Business Centre, 21-23 Elmfield Rd, Bromley BR1 1LT
Contact Details: +44 20 3193 8888
Operating Hours: Open 24 hours
The Solar Co. makes getting solar panels feel easy. Right from the start, their team walks you through everything—they’ll explain how solar works and help you choose what’s best for your home or business.
They collaborate with well-known brands like Sunsynk and SolarEdge. That means if you’re looking for something high-end, they can set you up with premium panels. This’ll give you more efficiency, so you get more power even on cloudy days.
For bigger business setups, they offer panels that handle extra power, or you can add battery storage like the Tesla Powerwall.
Something I noticed when talking to their customers was how the installers do clean, careful work and communicate well at every step. Folks really seemed to appreciate that, especially when it came to working on roofs or with home wiring.
Even after everything’s installed, they continue to support their clients. They’ll make time to do maintenance, grant paperwork, or just answer any questions you may have.
If there’s any downside, it’s that you might need to wait a bit longer during busy seasons, especially for bigger projects.
A top-quality install, great communication and a team that really knows their stuff
“We had solar panels and a battery installed at our home and couldn’t be happier with the whole experience. From the very first conversation through to installation and aftercare, Mark, Gerorge and the team were professional, knowledgeable and genuinely helpful. The installation itself was smooth, tidy and completed on schedule. The team clearly took pride in their work and explained everything in a way that was easy to understand, which gave us real confidence in the system. Since installation, the system has been performing brilliantly and the battery has already made a noticeable difference to our energy usage. Any questions we’ve had have been answered quickly and clearly and customer service has been excellent throughout. If you’re considering solar, I honestly couldn’t recommend this company highly enough. A top-quality install, great communication and a team that really knows their stuff.”

A local company that were brilliant, efficient and knowledgeable
“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.”

2. Excel Energy
Address: Urban Living Cucine, First Floor, 85 Great Portland St, London W1W 7LT
Contact Details: +44 20 3834 9440
Operating Hours:
- Monday to Friday – 8:00 AM to 5:00 PM
- Saturday to Sunday – Closed
It’s not every day you find a solar company that gets praised for both their technical skills and the way they treat people, but that’s exactly what stood out to me about Excel Energy.
With over 30 years of experience, they handle everything in-house, from the first chat and system design to equipment selection, careful installation, and ongoing support after it’s all up and running.
That attention to detail carries through to the equipment they choose. They work with trusted brands like SolarEdge, and don’t just offer a one-size-fits-all option—systems are designed for each property rather than pulled off a shelf.
Customers also love the clear communication, especially regarding paperwork, certifications, and grid approvals. We know that that stuff can be confusing, but Excel Energy seems to make it straightforward.
And if anything does go wrong, they back their work with a 5-year workmanship warranty. It gives customers a clear period of protection if an installation-related issue shows up after the system is fitted.
However, their tailored approach can mean projects take longer to kick off, especially compared to the larger, “fast fit” solar companies.
The installation team was professional, efficient, and took pride in their work
“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!”
– Ashwin Shah, Google Review
The quote was favourable, the whole process was smooth and efficient
“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!”

3. Discover Solar Ltd
Address: The Chocolate Factory, 5 Clarendon Rd, London N22 6XJ
Contact Details: +44 20 3633 0298
Operating Hours:
- Monday to Friday – 9:00 AM to 6:00 PM
- Saturday – 9:00 AM to 5:00 PM
- Sunday – Closed
Discover Solar offers bespoke system designs, tailoring solar PV and battery setups to suit the property rather than pushing a standard package.
They work with reputable brands such as Aiko Gen 2 panels and Fox ESS batteries, which gives some reassurance around performance and durability.
Each system includes online or app-based monitoring—something I consider essential, as it lets you track output and savings in real time.
Another thoughtful touch, especially for London homes, is the option to install anti-bird mesh to tackle the persistent pigeon problem that can damage or disrupt roof-mounted systems.
They also cover EV charger installations, either as part of a wider solar package or as a standalone service. Battery storage can be added independently, too; it’s pretty useful for those who already have panels installed.
But it’s worth mentioning that most of their packages tend to favour whole-system installs, so they may not be able to cater to you properly if you’re after a minor add-on.
Still, several customers report a fast timeline from survey to installation (often 2–4 weeks), which isn’t always the case in this industry. It’s probably because the team is comfortable working with challenging roof types and even ground-mounted systems.
Incredibly professional from start to finish, delivered on every promise
“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.”
– Sami Mahawish, Google Review
They answered all of my questions explained everything
“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.”

4. Acen Solar & Electrical Ltd
Address: Stratford Shopping Centre, 44 Broadway, London E15 1XH
Contact Details: +44 20 3005 3282
Operating Hours:
- Monday to Friday – 7:30 AM to 5:00 PM
- Saturday – 9:30 AM to 1:30 PM
- Sunday – Closed
When I first heard about Acen Solar & Electrical Ltd, I was impressed by how much they do. It’s not just solar panels—they offer batteries, electric car chargers, and a bunch of electrical services, too.
Their portfolio really stands out as well, with projects ranging from homes and commercial spaces to EV charger installations across London and the Southeast.
They even try out different products and have packages for both homes and businesses, including handy combos with battery storage.
Something else that put me at ease was their credentials. Acen is certified with MCS, NAPIT, and NICEIC, and they’re also part of the RECC Consumer Code.
And with those qualifications, it’s obvious that their installation team knows their stuff. From what many people have said, they can tackle just about any setup, whether that’s on a roof or an off-grid project.
Beyond the installation itself, Acen also ensures systems are looked after over time. Maintenance plans cover panels, batteries, and chargers, providing aftercare.
One thing to watch, though—they’re a bit choosy with the brands they install and don’t always give specifics about which panels you’ll get. If you care about exactly what’s going on your roof, just ask for details before you agree to anything.
Acen Solar did a fantastic job on my Solar install
“Acen Solar did a fantastic job on my Solar install. I had got quite a few different quotes and was finding a lot of companies were overpriced and inflexible. Aras was the complete opposite and I found him down to earth, helpful and willing to work with me to provide the equipment and install I was looking for. The quote was also itemised in terms of equipment / labour/ scaffolding which incredibly no other company seems to provide. Aras came round to do a survey within a few days and had the job done about 2 weeks later. I ended up fitting 14 panels which far exceeded my expectations in terms of generation and I’m over the moon about it. All documentation and MCS certificate was provided a few weeks after which was longer than I expected but understand there is a wait for DNO. Thanks Acen Solar, highly recommended!!!”
– Laurie Robinson, Google Review
It’s been a pleasure having the team on board
“So I recently had Aras and his team install and commission my solar and battery storage system, everything was explained and taken care of right from the start. It’s been a pleasure having the team onboard can’t thank them enough and highly recommend to anyone looking to get solar. All paper work inc registration with the DNO and MCS was taken care of. Thank you Aras and team.”

5. Emyra Solar
Address: Solar, Emyra, 17 Hanover Square, London W1S 1BN
Contact Details: +44 80 8280 0056
Operating Hours:
- Monday to Friday – 9:00 AM to 5:00 PM
- Saturday to Sunday – Closed
Emyra Solar works with Tier 1 panels and high-efficiency inverters, offering plenty of flexibility for on-grid, off-grid, hybrid, and battery storage setups.
Whether you’re a homeowner or running a big industrial site, each installation is tailored to your needs, with certified engineers designing the system on-site rather than using subcontractors.
Through this, I noticed a lot of people saying they finally feel in control of their energy bills, while business clients highlight how Emyra handles tricky sites and keeps maintenance running smoothly.
I also like their remote monitoring—every new system gets this, so you and the company both know if something’s off, often before you even notice it yourself. It’s a small thing that should give you peace of mind.
They back it all up with long warranties (up to 50 years!), and after-sales support that consists of maintenance, cleaning, and digital monitoring.
You don’t have to worry about any nasty surprises on your bill either. Emyra sticks to their fixed pricing, and they mention if any service or product has an additional cost.
But with their busy schedule across the UK and internationally, bigger projects can sometimes take a little while before getting started.
No hidden costs, no surprises – just solid work
“After comparing a few companies,we choose this one because they were upfront and easy to deal with. The 5.5kW solar system was installed neatly, with clear explanations throughout the day. No hidden costs, no surprises – just solid work and a system that’s already making a difference.”
– Theodore Wales, Google Review
The installation team was polite, efficient, and took the time to set up
“I compared several companies across the UK before choosing this one, and their price was by far the most competitive while still including quality components and full installation. Communication was clear from the start, and they explained everything in a way that was easy to understand. The materials were delivered quickly, and I only had to pay after I received them, which felt very reassuring. The installation team was polite, efficient, and took the time to set up the monitoring app and show me how everything works. Overall, a very professional service with excellent value for money”
