What is Naked Solar?

Naked Solar is a solar panel and battery installer with its head office at Quintrell Downs, just outside Newquay in Cornwall. It fits systems for homes, farms and businesses across the South West.

The company says it was founded in 2010 and traded as Cornwall Solar Panels until April 2017. It changed the name because the old one “didn’t really tell people what we believed”. The word “naked” stands for a service with “nothing to hide”, and its three stated principles are to give factual information, never to take commission from manufacturers, and to keep improving.

• It designs and installs. Solar panels, battery storage, EV chargers and upgrades to existing systems.
• It says it uses its own installers. Its website states: “We never sub-contract & all workmanship comes with a 10-year warranty.”
• It isn’t tied to one brand. It describes itself as “100% impartial” and says it never takes commission.
• It has a team of more than 50, by its own count, working from three sites.

Naked Solar’s team page names Tony Sampson as founder and managing director, and Shelley Sampson as finance and growth director, alongside an operations director and a sales director.

Naked Solar Ltd: company details

These details are from Companies House, for anyone who wants to check the business before signing a contract.

An active company with accounts filed up to date is what you want to see. Naked Solar gives 2010 as its founding year, and the limited company on the register dates from August 2011.

Where Naked Solar works: Newquay, Cornwall, Exeter and Bristol

People search for “Naked Solar UK”, but this is a South West installer. It doesn’t offer installation across the whole UK. It works from three sites, which it calls hubs:

Naked Solar Cornwall: the Newquay head office

Newquay is home to the head office. From there Naked Solar covers the whole of Cornwall, which takes in towns such as Truro, Falmouth, St Austell, Penzance and Bude. Cornwall has some of the best sunshine in the country, and a well-placed roof here generates about 1,050–1,150kWh a year for every kW of panels (solar panels in Cornwall).

Naked Solar Exeter and Devon

Naked Solar says it set up its Exeter installation and maintenance hub on the Sowton Industrial Estate in 2023, to give Devon customers a faster response. It covers Devon from there, along with parts of Somerset and Dorset (solar panels in Exeter).

Naked Solar Bristol

The Bristol hub at Avonmouth is the newest of the three. Naked Solar says it serves Bristol, Bath, Somerset and Swindon from there, and across the Severn to Newport and Cardiff (solar panels in Bristol, Bath, Swindon, Cardiff).

If you’re near the edge of these areas, ask which hub would look after you and how far its engineers would travel for a repair.

Naked Solar prices (2026)

Most installers don’t publish prices at all. Naked Solar does, which fits the name. This is the home price guide on its website, which it dates summer 2026.

Three things to take from the table:

• The guide sits above our typical UK range. The bottom of each range is close to the middle of ours, and the top is well above it.
• The ranges are wide. The page doesn’t say what puts a system at the top or bottom, or whether the top end includes extras. Treat the guide as a starting point and rely on your written quote.
• Home systems are charged at 0% VAT, which applies until 31 March 2027.

In our view, higher prices are consistent with what Naked Solar offers: its own employed installers, ten years on workmanship and a leaning towards premium kit. Whether that’s worth the extra is your decision, and the only way to judge is to compare its quote with another (solar panel cost).

On returns, Naked Solar says payback “typically ranges from 7–12 years”. By our sums, a 4kW system in the South West generates about 4,000–4,600kWh a year, worth roughly £770–£880 a year without a battery at October 2026 electricity prices (solar panel payback, are solar panels worth it?).

Deposit and payment terms

Naked Solar sets out its payment stages on its website:

1. £500 deposit to book your installation slot.
2. 60% of the price, less the deposit, ten working days before the installation. It says this pays for your parts.
3. The final 40% after the work is complete.

It says deposits and advance payments are held in a separate bank account and covered by insurance through the Renewable Energy Consumer Code. We didn’t find a finance offer on its website. If you want to spread the cost, ask (how to finance solar panels).

Naked Solar panels, batteries and storage

Naked Solar doesn’t sell one fixed package. It says you can “choose from any products on the UK solar market”. These are the brands and partner statuses named on its website:

Naked Solar batteries and storage prices

Naked Solar’s battery comparison page lists a price against each battery. These were the figures when we checked:

The page doesn’t spell out what each price includes. They look to us like the cost of a complete battery installation on its own, with its inverter. That’s a different thing from the £3,500–£5,500 we’d expect for a 5–10kWh battery added at the same time as new panels, so the two aren’t like for like. Get the battery priced as part of your whole system (are solar batteries worth it?, adding a battery to existing solar, Fox ESS review, Enphase review, Duracell review).

Naked Solar and Tesla Powerwall 3

Naked Solar says it is a Tesla Powerwall Premium Certified Installer and in the “top 3% of UK Powerwall installers”. Its awards page also lists a site excellence award from Tesla in 2024. A Powerwall 3 has 13.5kWh of usable storage, a built-in solar inverter and a 10-year warranty, and it can run a whole house in a power cut (Tesla solar review, battery backup in a power cut).

Octopus and grid trading

Naked Solar is an Octopus Trusted Partner, which it describes as Octopus Energy selecting it to install solar and batteries in the South West. It also promotes “solar grid trading”, where a battery sells stored power to the grid when prices are high. It says this can cut the payback period by one to two years. That depends on your tariff and how you use the battery, so ask for the assumptions behind any figure (Octopus solar review, Intelligent Octopus Go).

How a Naked Solar quote works

This is the process as Naked Solar describes it on its website:

1. Get in touch by phone or through the quote form. The form says the team will “be in touch shortly”.
2. Consultation. You talk through your home, your bills and what you want from the system.
3. Site survey and design. It describes a “bespoke site survey and design”, with the system modelled in PV*Sol.
4. Forecast and quote. It says a personalised forecast is emailed within two working days for a home, and that you get several options so you can compare systems on your own roof. It calls this “try before you buy”.
5. Deposit. £500 books your installation slot.
6. Installation, then a follow-up after one month and once a year after that.

It describes its quotes as “transparent” and “itemised”, with no obligation. Before you accept one, check these:

• Is scaffolding shown as a line in the price?
• Which panels, inverter and battery, by exact model?
• What yearly output in kWh is the design based on, and does it allow for shade?
• Is bird-proofing mesh included? (pigeon proofing solar panels)
• What’s the expected installation date?
• What does the workmanship warranty cover, and is it insurance-backed?

More on what a good quote contains is in how to choose a solar installer.

Naked Solar installation and wait times

Naked Solar doesn’t publish a wait time from order to installation. Its homepage says: “We’ve more than doubled the size of our team in the past year to bring waiting times down.” That tells you waits have been an issue it has worked on, but it isn’t a figure you can plan around. Ask for an expected installation week before you pay the deposit.

Part of any wait is outside the installer’s hands. Your local electricity network, which is National Grid Electricity Distribution across most of the South West, has to approve most battery systems before they’re fitted (how long does solar installation take?, how panels are installed).

Two to four days on site is longer than the single day some national firms quote. In our view that’s no bad thing. It suggests the job isn’t being rushed.

Naked Solar warranties and accreditations

Ten years on workmanship is as good as you’ll find from most UK installers, and it matters. It’s the cover for a leak, a loose cable or a bracket that wasn’t fixed properly (solar panel warranties explained).

Naked Solar lists a long set of accreditations on its website:

• MCS, which it says it has held since December 2010 (MCS certification explained)
• RECC, the Renewable Energy Consumer Code
• TrustMark, the government-endorsed quality scheme
• NICEIC, for electrical work
• CHAS and SMAS Worksafe, for health and safety
• B Corp. The B Corp directory shows a score of 91.0 and certification since June 2024
• Manufacturer statuses: Tesla Powerwall Premium Certified Installer, SunPower Elite Partner, REC Professional and Sigenergy Gold Installer

Its awards page lists the South West regional solar installer title at the Energy Efficiency Awards in 2025 and 2026, the national solar installer title in 2022, and a place among Business Cornwall’s Best Places to Work in 2026.

Naked Solar maintenance, aftercare and O&M

Naked Solar calls its Exeter and Bristol sites “installation and maintenance” hubs and says it has a dedicated aftercare team. Its aftercare page puts the offer like this: “Free post install advice & support. You only pay if we have to come to site and many issues are covered by warranties.”

• Advice by phone is free for its customers.
• A visit to site is charged, unless a warranty covers it. The call-out charge isn’t published, so ask what it is before you book.
• It publishes a fault-finding guide for inverters on its website.
• For most small systems, it says a yearly clean of the panels is all that’s needed.

For businesses, it offers “ongoing monitoring and support” after installation, which is the operations and maintenance, or O&M, side of a commercial system. It doesn’t publish contract terms or prices.

We couldn’t find a statement on whether it will service or repair a system fitted by another company. If that’s what you need, ask, or see solar panel servicing and solar panel maintenance.

Naked Solar reviews

What customers praise

In the positive reviews we read, the same things come up: consultations that focus on what the customer needs, clear explanations and pricing, tidy and careful installation, and staff who answer questions quickly. Some reviewers mention coming back to Naked Solar for further work.

Critical reviews

Critical reviews are a small minority. We read two. One Trustpilot reviewer felt the call-out charge for a visit was very high, while saying the service itself was good. One Google review, shown in the review feed on Naked Solar’s own website, describes repeated faults with the optimisers on a system about three years old, and a bill for third-party costs during a warranty repair. According to that review, a Naked Solar director responded and acknowledged there were lessons to learn.

These are individual customers’ own accounts, which we haven’t verified, and two reviews can’t tell you how a company performs overall. They do point to two sensible questions for any installer: what a call-out costs, and who pays for labour and access if a part fails under the maker’s warranty.

Read the most recent reviews yourself on Google and Trustpilot, and look at how the company replied.

Naked Solar vs other installers

The picture is clear enough. Naked Solar is strong on the things that are hard to fake: years in business, its own installers, a long guarantee and a full set of accreditations. Where it may lose out is price, and you can only know that by comparing.

If you’d rather buy from a national name, we’ve reviewed Heatable, Octopus, BOXT, E.ON and British Gas, and compared them in solar panel companies UK. Outside the South West, start with solar panel installers near me.

Commercial solar from Naked Solar

Naked Solar also fits systems for businesses and farms. Its commercial price guide starts at £12,666–£21,140 plus VAT for 10kW and runs to £68,508–£132,231 plus VAT for 100kW. Its website shows projects at golf clubs, holiday parks and manufacturers across the South West (commercial solar panels).

Naked Solar jobs

Naked Solar is recruiting, and “Naked Solar jobs” is a common search. These were the roles on its careers page when we checked on 6 October 2026:

Applications go through the company’s page on Indeed. The benefits it lists include health and travel insurance, the option to increase holiday to 38 days a year, a cycle-to-work scheme and flexible hours. It also runs its own installer training. Vacancies change often, so check its careers page for the current list. We’re not connected with Naked Solar and can’t pass on applications.

Naked Solar or Naked Energy?

The two names get mixed up, and they’re different companies.

• Naked Solar is the Cornwall-based installer this review is about. It fits standard solar panels and batteries on homes and businesses.
• Naked Energy is a separate British company that designs and makes solar collectors. Its VirtuPVT product is a hybrid that produces electricity and heat from one unit, and its VirtuHOT product produces heat. Both are aimed at commercial and industrial buildings.

So if you searched for “naked hybrid solar panels”, you’re looking for Naked Energy. As far as we can tell, the two have no connection. For how heat-producing panels differ from the usual kind, see solar thermal vs solar PV.
