About Haverstone Ltd

Haverstone Ltd is the official UK agent for Biolectric NV, Europe’s leading manufacturer of small-scale, slurry-only anaerobic digestion (AD) systems. We work with dairy and pig farmers across the UK to help them turn their slurry into renewable energy and long-term value for their business.

Haverstone Ltd trades under the name Dairy Energy, a brand dedicated to supporting British farmers in producing their own green electricity and improving nutrient management. Whether you see us as Haverstone Ltd or Dairy Energy, it’s the same team — providing UK-based knowledge, guidance, and on-farm experience to support the rollout of Biolectric technology.

Every Biolectric system is designed, built, and factory-tested in Belgium before being delivered to the farm as a complete, plug-and-play unit. The result is a compact, automated system that transforms slurry into clean electricity and heat, while reducing fertiliser costs, improving soil health, and cutting greenhouse gas emissions.

Our Role

Haverstone Ltd acts as Biolectric’s official UK agent, supporting farmers at every stage of the process — from initial discussions and feasibility assessments to planning guidance, grid connection advice, and funding introductions. We ensure that every project is properly scoped, clearly explained, and well supported.

All contracts, warranties, and guarantees are held directly with Biolectric NV, giving every customer complete confidence that they are dealing directly with the manufacturer. Haverstone’s role is to make the process smooth and practical on the ground — ensuring clear communication, realistic expectations, and dependable local support through Biolectric’s UK engineering network.

Why Work With Us

• We make small-scale AD straightforward, handling the technical detail so you can focus on the farm.
• We help you assess feasibility, from energy use to slurry availability and site layout.
• We bridge the gap between your farm and the manufacturer, ensuring a smooth installation and long-term performance.
• We provide ongoing local support, backed by Biolectric’s dedicated UK team of engineers.

With energy costs rising and pressure to reduce emissions increasing, small-scale AD is one of the most effective ways to future-proof your farm.

Haverstone Ltd (trading as Dairy Energy) is here to make that journey clear, achievable, and rewarding — with proven European technology, direct manufacturer contracts, and trusted UK support.
