Project Solar UK

What Project Solar UK does

Project Solar UK Limited is a privately held, UK-based residential solar installer and a subsidiary of Project Better Energy Group. Headquartered in Burton-on-Trent with customer support in Manchester and operations spanning the North West and Midlands, the company designs, supplies and installs rooftop solar PV and battery storage systems for UK homeowners, operating nationwide across England, Scotland and Wales. Itself-claims to be the UK's largest independent solar panel installer and has completed over 50,000 residential installations since 2011.

The company's core offerings are solar PV panels carrying a 99-year manufacturer product warranty, lithium battery storage systems with a 15-year warranty, and an add-on EV charger priced at £699. The Project Solar App delivers real-time monitoring of generation, battery state and grid flows, while Project Solar+ — an AI-driven battery and grid optimisation service operated in partnership with Joulen (Power On Technologies) — automates charging, discharging and export decisions using weather forecasts, time-of-use tariffs and grid-services signals, with integration into National Grid ESO flexibility markets. The technology stack combines MCS-certified installation standards with monitoring platforms such as Solax Cloud and FoxESS, regulatory certifications (HIES, NAPIT, Trustmark, CTSI Consumer Code, FCA credit broking under FRN 704308) and a Year One Performance Guarantee.

Project Solar operates a direct-to-consumer model: customers enter the funnel via a free online quote on energy.projectsolaruk.com or via the 0800 112 3110 national phone number, proceed to an on-site survey, then installation by Project Solar's own field teams. Hardware and installation revenue is captured through four payment pathways — cash, fixed-payment finance, leasing and Buy Now Pay Later via Tandem at 8.9% APR — with additional credit-brokerage commission, optional Project Solar+ grid-services participation and customer referrals forming supplementary revenue streams. Customer acquisition is heavily content- and PR-led, anchored by brand ambassador Kevin McCloud, Trustpilot reputation management, and seasonal campaigns including Black Friday and Refer-a-Friend promotions.
