Interview Charlton Park biogas plant UK: five years of grid quality biomethane
9 November 2026
We have published a new case study on the turnkey biogas plant we built for project developer Lepus Energy at Charlton Park Estate in Malmesbury, UK. The facility converts 47,500 tonnes of organic residues and manure into 4.8 million Nm³ of biomethane each year, enough to cover the gas needs of more than 3,800 average UK homes while cutting CO2 emissions by around 10,800 tonnes a year.
Client interview
Five years after start of operations, the Charlton Park biogas plant near Malmesbury, Wiltshire, still delivers grid-quality biomethane with minimal intervention. Stuart Homewood, CEO of Lepus Energy, explains how the plant has performed and how the collaboration with HoSt works in practice.
Scope of supply
HoSt supplied the plant as a full EPC turnkey project. It combines anaerobic digestion with membrane biogas upgrading and converts 47,500 tonnes of organic residues per year into biomethane for the national gas grid.
In the video interview
- Robust performance from feed system to mixing, with redundancy that lets one mixer go offline without disrupting the process
- Maintenance intervals extended beyond the standard schedule while the process stays stable
- Remote monitoring and control with HoSt SCADA, backed by service and maintenance support
- A partnership in which Lepus plant managers and HoSt engineers work as one team
“It’s very collaborative. You’re almost a team, even though you’re separate companies.”
