BOXT Solar Panels Review: Prices, Reviews & Alternatives
BOXT built its name selling boilers online with fixed prices and fast installs, and it now sells solar panels and home batteries the same way. You get an instant online quote, AIKO panels, and a choice of Sunsynk or Tesla Powerwall 3 batteries.
Its £3,999 starting price is well below EDF’s £5,775 for the same number of panels. The things to check are what that price buys, the extras that sit on top, and a workmanship guarantee of just 2 years.
Quick Answer
BOXT solar panels start at £3,999 for a 4-panel system with AIKO panels, installed in two to three days. That is cheaper than EDF's £5,775 four-panel price, but most homes need 6 to 14 panels, battery storage is extra (Tesla Powerwall 3 from £7,345), BOXT does not fit flat roofs, and its workmanship guarantee is only 2 years.

BOXT solar panels reviews
BOXT has a Trustpilot TrustScore of 4.7 from 65,906 reviews, which is excellent. But BOXT started as a boiler company and most of those reviews are about boilers, so the score says more about its boiler installs than its solar ones.
Solar-specific feedback is thinner and more mixed. Reddit’s r/SolarUK has several BOXT threads, including one titled “A cautionary tale” from July 2026, and a recent Trustpilot review complains of a delayed install and a missing handover pack and DNO paperwork months later.
Before you sign: ask BOXT who will carry out the installation, when you will receive your MCS certificate and handover pack, and what happens if something goes wrong after the 2-year workmanship guarantee ends.

Choose BOXT if…
- You want an instant online price without a home visit
- You want a quick install, typically two to three days
- You are happy with AIKO panels and a Sunsynk or Tesla battery
- You can use the B&Q discount or a current BOXT offer
Choose an independent installer if…
- You have a flat roof, or live on a UK island
- You want a longer workmanship guarantee than 2 years
- You want other equipment, such as Sigenergy batteries
- You want a surveyor to visit before you commit
Our take
BOXT’s pricing is genuinely competitive and the online process is quick. The trade-off is a 2-year workmanship guarantee and limited solar-specific reviews. Use a BOXT quote as a benchmark, then get at least two quotes from local MCS-certified installers for the same number of panels and ask each how long their workmanship guarantee lasts.

BOXT Solar Panels FAQ
How much do BOXT solar panels cost?
BOXT's published starting price is £3,999 for a 4-panel system including installation, with 0% VAT. A battery is not included in that price. Most homes need more panels: BOXT says smaller homes need 6 to 10 and larger homes 10 to 14, so get a full quote for your roof.
Is BOXT a reliable company?
BOXT is MCS certified and TrustMark registered, and has a Trustpilot TrustScore of 4.7 from 65,906 reviews. Most of those reviews are for boilers, its original business, so they tell you less about its solar installs. Experiences shared on Reddit's r/SolarUK are mixed. The main weakness on paper is a 2-year workmanship guarantee.
Who is BOXT owned by?
BOXT Ltd is a privately owned UK company. It started out selling and fitting boilers online and now also sells solar panels, home batteries, heat pumps, air conditioning and EV chargers. It is not part of an energy supplier.
What solar panels does BOXT use?
AIKO panels, which BOXT lists at 24.3% efficiency. For batteries, it offers the Sunsynk Elite or the Tesla Powerwall 3, both with an integrated inverter and a 10-year manufacturer warranty.
How much is a Tesla Powerwall 3 from BOXT?
BOXT lists the Powerwall from £7,345, with up to £750 back on installation under its Powerwall 3 rebate terms. The Tesla Backup Gateway, needed for power-cut protection, is not included and costs an extra £500.
Is there a BOXT solar panels promo code?
BOXT does not publish a standing promo code for solar. B&Q customers can get £200 off BOXT solar and home battery storage through B&Q's partnership, and BOXT has advertised a "buy one panel, get one free" offer. Check the current terms before you order.
Does BOXT install solar panels on flat roofs?
No. BOXT says it does not install solar panels on flat roofs. It also only installs on residential properties in mainland UK, excluding islands, and not on commercial buildings.
What warranty do BOXT solar panels come with?
Panels carry a manufacturer warranty (BOXT's solar page says 30 years for product and performance; its terms say 25 years as standard, so check your paperwork). Batteries have a 10-year manufacturer warranty. BOXT's own workmanship guarantee lasts 2 years and is insurance-backed.
Does BOXT offer solar finance?
Yes. BOXT offers 0% finance over up to 48 months (its example is 8 panels for £5,199: a £926.98 deposit, then £89 a month for 48 months), or up to 180 payments at 6.0% APR from £22 a month. All are subject to status.
