What Square 4 Solar does
Square 4 Solar (SQ4S), trading as Square 4 Services Ltd (Companies House registration 10512712), is a UK-based commercial solar PV installer headquartered in Warrington. The company was founded around 2016 and operates with a headcount in the 11-50 band. Its core business is the design, supply, installation and maintenance of rooftop solar PV systems for commercial and public-sector customers, with a documented project base spanning national retail (Lidl GB, Premier Inn), higher education (Lancaster University), the NHS (University Hospital of North Tees), blue-light services (Greater Manchester Fire & Rescue) and schools (Pear Tree High School). Revenue mechanics combine one-off EPC contracts on a framework and tender basis with an in-house operations and maintenance service (energWISE) launched in January 2023 to generate recurring post-installation revenue. The go-to-market is anchored by a national framework agreement with Lidl GB (signed December 2019) covering 60+ completed installations and a pipeline of 100+ stores, supplemented by approved-installer status with Bauder for bio-solar green roof systems (April 2023) and a CPD-accredited training programme (April 2023) targeting M&E consultants and specifiers at the design stage. Underlying technology is mainstream commercial PV (modules, inverters, mounting, monitoring), with a strategic equipment partnership with Huawei/Segen (June 2022) supplying component access. Pricing and contracting follow standard UK commercial PV EPC structures; Square 4 holds the relevant accreditations (MCS, NAPIT, ConstructionLine, GRO, Acclaim H&S) required to tender public-sector and large-enterprise work.
