Summary

The UK Secretary of State has issued the Non-Domestic Rating (Renewable Energy Projects) (Amendment) Regulations 2026, amending the 2013 Regulations. These changes, effective April 1, 2026, introduce new definitions and calculations for relevant multiplier ratios related to non-domestic rating of renewable energy projects.

What changed

The Non-Domestic Rating (Renewable Energy Projects) (Amendment) Regulations 2026 amend existing regulations concerning the non-domestic rating of renewable energy projects in England and Wales. Key changes include amendments to the definition of "non-domestic rating income" and the introduction of a new definition and calculation formula for "relevant multiplier ratio" within regulation 13. These amendments modify how non-domestic rates are calculated for certain renewable energy hereditaments.

These regulations are effective from April 1, 2026. Businesses involved in renewable energy projects, particularly those subject to non-domestic rates, should review the updated definitions and calculation methods for "relevant multiplier ratio" to ensure accurate rateable value assessments and compliance with the revised provisions. While no specific compliance deadline is mentioned beyond the effective date, understanding these changes is crucial for financial and legal departments managing property tax liabilities.

What to do next

  1. Review amendments to regulation 2 (interpretation) and regulation 13 (non-domestic rating income) of the Non-Domestic Rating (Renewable Energy Projects) Regulations 2013.
  2. Understand the new definition and calculation formula for "relevant multiplier ratio" as introduced by regulation 4.
  3. Assess the impact of these changes on non-domestic rateable values for renewable energy projects and ensure accurate financial reporting.

Explanatory Note

(This note is not part of the Regulations)

These Regulations make amendments to the Non-Domestic Rating (Renewable Energy Projects) Regulations 2013 (S.I. 2013/108) (“ the 2013 Regulations ”).

The 2013 Regulations designate classes of hereditaments in relation to which a billing authority may disregard an amount of non-domestic rating income for the purpose of certain calculations under Schedule 7B to the Local Government Act 1988 (local retention of non-domestic rates).

Regulation 13 of the 2013 Regulations makes provision for the calculation of the non-domestic rating income in respect of a hereditament within a designated class, and regulations 14 to 18 make provision for the amounts to be disregarded in respect of each designated class.

The Non-Domestic Rating (Multipliers and Private Schools) Act 2025 amended Schedule 7 to the 1998 Act to make provision for the introduction of additional multipliers for financial years beginning on or after 1st April 2026.

These Regulations adjust the way in which the amounts to be disregarded under regulations 14 to 18 of the 2013 Regulations are calculated, by introducing a scaling factor in regulation 13 of those Regulations to remove the impact of the additional multipliers on the total amounts of non-domestic rating income that a billing authority may disregard in respect of hereditaments to which the 2013 Regulations apply.

An impact assessment has not been produced for this instrument because it amends an existing local tax regime.

(1) 1988 c. 41. Schedule 7B was inserted by section 1 of, and Schedule 1 to, the Local Government Finance Act 2012 (c. 17) and amended by section 9 of the Non-Domestic Rating Act 2023 (c. 53).

(2) S.I. 2013/108, amended by S.I. 2017/1132 and 2024/184.

(3) Paragraph A6A was inserted in Schedule 7 by section 1(3) of the Non-Domestic Rating (Multipliers and Private Schools) Act 2025 (c. 12).

(4) Part A1 was inserted in Schedule 7 by section 15(2) of the Non-Domestic Rating Act 2023.
