Hydrolysis (Scotland) Regulations 2026

The Hydrolysis (Scotland) Regulations 2026 are two Scottish Statutory Instruments — SSI 2026/50 (the No. 1 Regulations) and SSI 2026/51 (the No. 2 Regulations) — that together legalise and regulate alkaline hydrolysis (water cremation) as a method of disposing of human remains in Scotland. They were made under the Burial and Cremation (Scotland) Act 2016 and came into force on 2 March 2026, making Scotland the first part of the UK to permit the method.

What the No. 1 Regulations (SSI 2026/50) do:

  • Extend the framework of the Burial and Cremation (Scotland) Act 2016 to cover hydrolysis facilities, applications, record-keeping, and oversight on the same model as crematoriums.
  • Set out the application process for carrying out a hydrolysis on a deceased person.
  • Set out the operational requirements for the procedure itself.
  • Require facility operators under the Burial and Cremation (Scotland) Act 2016 regime to maintain a hydrolysis register and to retain records for 50 years.
  • Set out closure protocols and consequential amendments to legislation as far back as the Anatomy Act 1984.

What the No. 2 Regulations (SSI 2026/51) do:

  • Introduce the new certification forms required for hydrolysis (in parallel with the existing forms for burial and cremation).
  • Add pregnancy-loss documentation tailored to hydrolysis.
  • Make consequential amendments to other regulations to integrate hydrolysis into Scotland's existing disposal regime.

Operational impact for families:

  • Choosing alkaline hydrolysis works the same way as choosing flame cremation: instruct a funeral director, who arranges the procedure with a licensed facility.
  • The family receives the processed remains back in an urn.
  • The same rights apply to what the family does with the remains — scatter, bury, retain at home.

What the Regulations do not cover:

  • They are not retrospective for existing burial rights; the new 25-year burial-right tenure introduced in parallel applies only to new rights granted from 1 March 2026.
  • They have no extra-territorial effect — they regulate hydrolysis in Scotland only. England and Wales would need separate primary legislation; the Law Commission is consulting on a wider funeral-law reform.
  • They do not create or fund hydrolysis facilities. The Regulations create the legal framework; commercial providers must still secure planning permission and a Scottish Environment Protection Agency (SEPA) discharge consent before operating.

Operational status (May 2026): no facility is yet operational in Scotland. The Scottish Government has estimated a six-to-nine-month gap between the law coming into force and the first facility opening, suggesting late 2026 to early 2027 as a realistic window for the first operational hydrolysis service. Families currently arranging funerals in Scotland cannot yet choose alkaline hydrolysis in practice, although the legal route is now in place.

Background: the Regulations followed a Scottish Government consultation in 2023 and a published consultation analysis in 2024 that recorded majority public support (around 84% of respondents). An Alkaline Hydrolysis Working Group, including faith representatives, environmental regulators, and funeral industry stakeholders, advised on the regulatory shape.
