Agrivert Group

What Agrivert Group does

Agrivert Group is a UK-based specialist renewable energy company founded in 1994 by Alexander Maddan, headquartered in Witney, Oxfordshire, with a registered office in Chipping Norton. The group designs, builds and operates anaerobic digestion (AD) facilities that convert food waste, sewage sludge, agricultural residues and energy crops into biogas, biomethane and organic digestate fertiliser, and additionally specifies, installs and maintains solar PV and battery storage systems through its wholly owned subsidiary Chiltern Solar (acquired October 2023). Agrivert is technology agnostic, integrating third-party process components (e.g., Jenbacher engines, HoSt and Wackerbauer hammermills, Huning silos) and applying proprietary design and turnaround know-how that has historically delivered ~97% of maximum output across its legacy fleet, versus a UK fleet average of 82%.

The service offering spans the full AD lifecycle: fixed-price EPC contracts (including the £225m / HKD 2.1bn O·PARK2 food waste AD facility in Hong Kong, delivered via the AJA Joint Venture with Alchmex and JEC), multi-year Operations & Maintenance contracts (e.g., Severn Trent Green Power, Ingenious portfolio 2019-2024, Charlton Park, Manor Farm, Tornagrain, and a 15-year O&M for O·PARK2), plant turnarounds and engineering consultancy, plus gate fees for organic waste processing under 44+ historical UK local authority contracts. In March 2024 Agrivert formed the Beacon joint venture with Low Carbon to develop 30-40 biomethane plants across Europe, with InCommodities taking a minority stake and offtaker role in December 2024. Customers span UK local authorities, water utilities (Northumbrian Water, 16+ years), renewable energy asset owners and investors (Severn Trent Green Power, Ingenious, SWEN Capital Partners, RAW Energy, HoSt Group), and international government clients (Hong Kong EPD), reached primarily through direct enterprise field sales, with the Beacon JV serving as a channel partner for European biomethane.

Revenue model

1. EPC contracts (Engineering, Procurement, Construction): Fixed-price turnkey construction contracts for AD facilities (e.g., Derby plant retrofit, Hong Kong O·PARK2 at £225m/HKD 2.1bn). Long-cycle, one-time revenue per project.
2. Operations & Maintenance (O&M) contracts: Multi-year operational and maintenance contracts for third-party-owned AD plants (e.g., Ingenious portfolio 2019–2024, Hong Kong O·PARK2 15-year operating contract, Severn Trent Green Power Derby facility, Manor Farm, Tornagrain). Includes both fixed management fees and performance-based fees.
3. Renewable energy / biogas / biomethane sales: Generation-based revenue from electricity exported to the grid (legacy CHP plants) and biomethane injected to gas grid from AD plants operated by Agrivert. Supported historically by Feed-in Tariff, Renewable Obligation, and Green Gas Support Scheme tariffs.
4. Waste processing gate fees: Per-tonne gate fees received from local authorities and commercial waste producers for accepting food waste, sewage sludge, and crop feedstocks at Agrivert's AD and composting facilities (44+ UK local authority contracts historically).
5. Solar PV and battery storage installations: Revenue from design, supply, installation and maintenance of rooftop solar PV and battery storage systems for commercial, agricultural, and domestic UK customers via the acquired Chiltern Solar business; future financing options planned.
6. Engineering consultancy and performance reviews: Diagnostic, design and consultancy services for AD plant owners (e.g., operational reviews and engineering upgrade recommendations for underperforming AD plants). Project-based revenue.
7. Equity participation / asset ownership via Beacon JV: Agrivert co-owns Beacon (JV with Low Carbon; minority investment by InCommodities) to develop, build and operate biomethane plants across Europe, generating equity returns and project development fees.

Core offering

Agrivert Group designs, builds and operates anaerobic digestion (AD) facilities that convert food waste, sewage sludge, agricultural residues and energy crops into biogas, renewable electricity, biomethane and biofertiliser. Through its wholly owned Chiltern Solar subsidiary it also specifies, installs and maintains solar PV and battery storage systems for commercial, agricultural and domestic customers. The group is technology-agnostic and delivers EPC, multi-year operations & maintenance, plant turnaround and engineering consultancy services in the UK and internationally.

Product overview

Agrivert Group operates as a platform-plus-acquired-brands renewable energy business rather than a single unified product. Its core offering is the design, build and operation of anaerobic digestion (AD) facilities (the North London AD, South Wales AD, Manor Farm, Tornagrain, Derby and Hong Kong O·PARK2 facilities being the named installations), supported by AD retrofit/enhancement, operation & maintenance, and turnaround services. Through the October 2023 acquisition of Chiltern Solar Limited, Agrivert added Solar PV and battery storage design, installation and maintenance for commercial, agricultural and domestic clients as a second service line. In March 2024 Agrivert partnered with Low Carbon to form Beacon, a JV platform targeting 30–40 biomethane/biogas plants across Europe by 2030, in which InCommodities took a minority stake in December 2024. Historically, Agrivert also offered In-Vessel Composting, open-windrow green waste composting and biosolids dewatering/liming assets, most of which were sold to Severn Trent Green Power in 2018. The group is technology agnostic and delivers these services across the UK (head office in Witney, Oxfordshire) and internationally (notably Hong Kong).
