Barber's Farm in Somerset installed three milk source heat pumps, achieving over £70,000 in annual electricity savings and cutting carbon emissions by nearly 60 tons. The pumps cool milk to 4C and produce high-grade hot water at 92C, replacing older systems.

Energy savings reported include £20,808 and £19,710 for two farms, with a projected £31,775 for the third, totaling £72,288 across all farms. The technology, developed by Arkaya Energy, has been commercially installed on over 20 dairy farms in the UK since 2023 and received the Royal Dairy Innovation Award in 2026.
