Here are the factors we considered, which we’d recommend you think about too.AccreditationsYou 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 reviewsIt’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.ExperienceIdeally, 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.

Q&A How big is your solar panel system, and how roughly much did it cost? “We have a 5.76 kilowatt (kW) system, comprising of 16 360 watt (W) fully black Canadian solar panels. They’re connected to a Solis 5G 5.0 kW dual tracker inverter, with direct current (DC) isolation […].“We paid just under £5,000 for the whole system, and £750 for an electric car charging port.” What was the experience like buying the panels? “I searched for quotes online, and three [installers] got back to me.“We had two of the three come out and see the house, and we went with the cheapest option […].“The scaffolders came one Friday afternoon. The equipment was dropped off that day, and kept in our garage. […] The panels were up by Sunday morning, and the scaffolding was down Monday.” How much money do your solar panels save you on your electricity bills? “I know that the first month after we installed the panels, we went from £90 [a month] to £45-50.” Best for London & South East England: Everyone’s Energy UKTrustPilot customer ratingNumber of reviewsFoundedBased in4.82432019HertfordIn 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 Pros High rating Partners with Solar Together, so you can get solar panels installed for 30-35% less Passionate about saving you money Cons Relatively low number of reviewers, so you can't be certain they accurately reflect the service 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.”Graham Dorneyt, January 2024, TrustPilot Best for the Midlands: The Eco Roof and Wall CompanyTrustPilot customer ratingNumber of reviewsFoundedBased in3.7592003NottinghamAs 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 Pros Family-run company, assuring a friendly, personal response Two decades of experience, a rarity in the industry Well-versed in a variety of green products, so you can more than one eco-friendly retrofit done with them Cons Rating could be higher 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 RepairTrustPilot customer ratingNumber of reviewsFoundedBased in4.830,6332017County DurhamLet’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 Pros Incredibly high number of happy reviewers, so there's a higher chance these reviews accurately reflect the service It has an in-house training academy, so you can be sure all their installers are up to scratch Excellent rating, the best rating to number of reviews ratio on our list Cons Not nationwide, a real shame for such a highly rated company Customer feedback“Excellent, very thorough inspection and explained everything in full.

No it’s not harder to sell a house with solar panels – in fact, it can sometimes be easier, since solar panels are increasingly popular in the UK. Over two-thirds of Brits would be likely to buy a property that had solar panels, according to our latest National Home Energy Survey.Having solar panels installed on your roof can increase the value of your property by around 4.1%. Do I need to tell my electricity supplier that I have solar panels? Yes, if your solar panels are connected to the grid, you need to notify your Distribution Network Operator (DNO) that you’ve installed them. You won’t need to worry too much about this, since your installer will usually do this for you.Energy distributors need to know if you are exporting electricity back onto the grid so that they can manage their energy levels efficiently. How much do solar panels cost in the UK in 2024? The average cost of solar panels in the UK is £786 per panel, meaning a three-bedroom house will typically pay £7,860 for 10 solar panels.You can choose to buy more expensive solar panels for higher efficiency levels, which may allow you to reduce the average break-even point of 12.9 years. What to check before installing solar panels The most important thing to check before installing solar panels is the condition of the roof – it needs to be strong enough to hold the weight of several solar panels.Your installer will do this before beginning the installation. They’ll ask you for your energy usage to calculate how many solar panels you need, and check the orientation and angle of your roof, as this can affect how much energy the panels produce.For example, solar panels on north-facing roofs produce 20% to 40% less than ones on south-facing roofs.
