BioWatt

What BioWatt does

BioWatt is a Bedford, UK-headquartered specialist founded in 2012 by James Lloyd and Iain Steel, focused exclusively on anaerobic digestion (AD) and renewable natural gas (RNG) projects. The company operates four service lines spanning the full AD asset lifecycle: multi-site operations, asset management, project development and funding, and construction management (including FEED and contract management). BioWatt operates, or has been involved in the construction of, more than a dozen UK biogas plants since 2015, handling over 200,000 tonnes of feedstock and digestate per year across sites including Marsh Farm (Basildon), Station Works (Thaxted), Buttermilk Hall Farm (Buntingford), Brigg Lane/Bonby, Deal Farm (Diss), and the Wincanton/Brains Farm RNG facility, which commenced operations in February 2025.

The company's core technology stack combines an in-house cloud-based project, document and contract management platform used across construction and development projects with the Smart-Ops operations data platform (spun out of BioWatt in July 2020), which captures geo- and time-stamped operational data from operators' smart devices and feeds web-based performance dashboards and alerts. BioWatt also deploys specialist biological optimisation techniques (e.g., FM Bioenergy's BC.MICROcon5 micronutrient dosing protocols) that have demonstrated the ability to recover underperforming plants, such as taking the Katharos AD facility from ~60% capacity to >850kW output at lower feed rates.

BioWatt generates revenue through (i) professional services fees for FEED, planning/permitting, procurement, construction project management and HAZOP/HAZID work, (ii) long-term managed services contracts for multi-site operations, asset management, finance management, compliance (PAS110, ISAE300, FMS, planning), insurance broking, and subsidy/green certificate trading, and (iii) transaction and advisory fees for project finance, M&A due diligence and financial close support. The customer base is concentrated in enterprise clients — blue-chip energy infrastructure investors (Vida Bioenergy/VTTI, Storengy/Engie), water utilities (Anglian Water), local authorities (London Borough of Hounslow, other unnamed councils), and landowners/farmers — served through a direct enterprise field sales motion backed by an ecosystem of technology vendors (Xergi, Weltec, Clarke Energy, 2G, Jenbacher, Air Liquide), civil contractors, legal advisors (Michelmores LLP) and feedstock partners (Bioganix).
