What Alt-group does

Alt-Group is a UK-based, privately-held renewable energy EPC and technology provider headquartered in Worcester, with a regional office in Derby. Founded in 2017 as Alt-Energi Ltd by Phil Mole and Will George, the group operates through three wholly-owned divisions — Alt-Solar, Alt-Energi and Solar Mounting — brought together under a single Alt-Group brand in September 2025. The company delivers end-to-end commercial solar PV, battery energy storage systems (BESS), solar carports, and UK-manufactured mounting hardware, alongside consulting, design, installation, and long-term operations and maintenance services for projects ranging from 50kW rooftop arrays to 16MW ground-mount installations and 200MW+ portfolios.

The company's technology stack combines AC- and DC-coupled solar PV and BESS, proprietary mounting systems (P-Type, S-Type, A-Type, M-Type, B-Type and G-Type foundations) manufactured in Britain with 25-year guarantees, in-house design engineering aligned to Eurocode standards, and active performance monitoring with thermal imaging and DC string testing. It serves commercial and industrial, agricultural, developer, public sector and real estate clients through a direct enterprise field-sales motion with dedicated project managers and sector-specialist business development.

Alt-Group monetises through a mix of one-time EPC project revenue (CapEx sales), subscription-style asset finance contracts, Power Purchase Agreements with third-party funders, and recurring Operations & Maintenance contracts. The business is bootstrapped with no external institutional investment disclosed, holds a full suite of UK sector accreditations (MCS, NICEIC, NAPIT, Achilles Network Silver Plus, Made in Britain, among others), and reports quantified customer outcomes including 20–50% electricity bill reductions, 2.8–4 year payback periods, and CO2 avoidance in the hundreds of tonnes per installation.

Revenue model

1. Solar PV System Sales & Installation: Alt-Group designs, installs and commissions solar PV systems for commercial, industrial, agricultural and public sector clients. Revenue is generated through EPC (Engineering, Procurement and Construction) contracts for ground-mounted, roof-mounted, and carport solar installations. Payment is received upon project completion with optional financing arrangements.
2. Battery Energy Storage Systems (BESS): Sale and installation of battery storage systems integrated with solar PV or standalone, providing peak shaving, load management, and backup capabilities. Systems help reduce demand charges and optimise self-consumption.
3. Operations & Maintenance (O&M) Services: Long-term maintenance contracts providing active monitoring, preventative maintenance, reactive engineering support, and performance reporting for installed solar and storage assets. Includes warranty management and lifecycle optimisation services.
4. Mounting Systems Manufacturing & Sales: Design, manufacture and supply of commercial solar mounting systems including P-Type, S-Type, A-Type, M-Type, B-Type, and G-Type solutions. All systems manufactured in Britain with 25-year guarantees.
5. Consulting & Feasibility Services: Technical feasibility studies, financial modelling, ESG advisory, and initial consultation services to assess site suitability and project viability. Initial consultation offered at no cost.
