Overview

• The independent Law Commission has opened a consultation on legalising alkaline hydrolysis, known as water cremation, which remains effectively banned under UK funeral regulations.
• The process uses water, potassium hydroxide, heat and pressure to reduce bodies to sterile liquid and bone ash, discharging DNA-free effluent into wastewater systems.
• Co-op Funeralcare revived plans in 2023 to offer water cremation services but has been unable to proceed pending regulatory approval.
• Supporters highlight that water cremation emits about 28kg of CO2 per cycle—compared with roughly 245kg for gas cremation—and avoids mercury and other harmful emissions.
• Already offered in nearly 30 US states, Canada, South Africa and Ireland since 2023, water cremation typically costs between $1,500 and $5,000, similar to traditional cremation fees.
