The Regulations amended the Customs (Northern Ireland) (EU Exit) Regulations 2020 to correct errors, introduce 'interchangeable goods' provisions under Chapter 6 for repayment/remission claims, and link Chapter 5 relief to Chapter 6 claims, while inserting a 'fit and proper person' test for certain claims.

The Customs (Northern Ireland) (EU Exit) (Amendment) Regulations 2026 modify the existing 2020 Regulations concerning customs duties in Northern Ireland post-EU exit by correcting minor errors across several chapters and introducing two key substantive changes: establishing a linkage for claims between the Chapter 5 relief scheme and the Chapter 6 repayment/remission scheme, and introducing a mechanism for 'interchangeable goods' claims where identifying specific goods is impracticable due to mixing.

The commencement date for the Customs (Northern Ireland) (EU Exit) (Amendment) Regulations 2026 was officially changed from 20th April 2026 to 25th May 2026.

These Regulations, officially titled The Customs (Northern Ireland) (EU Exit) (Amendment) (No. 2) Regulations 2026, introduce a technical amendment to delay the enforcement date of a preceding Statutory Instrument, specifically S.I. 2026/393.

The Treasury exercised powers under the Taxation (Cross-border Trade) Act 2018 to move the commencement date for specific customs amendments in Northern Ireland from April 20th, 2026, to May 25th, 2026.

The North East Combined Authority's maximum tolls for the Tyne Tunnel crossing were revised and specified in a new schedule, effective May 1, 2026, following the revocation of the 2025 toll revision order.

Expanded pension eligibility to include elected members and mayors of the Sussex and Brighton Combined County Authority.

The Sussex and Brighton Combined County Authority is directed to make the necessary employer contributions and payments to fund these pension benefits for its members.

Created a new statutory body called the Birmingham East Mayoral Development Corporation to oversee urban development in a designated section of the West Midlands.

This Order establishes a Mayoral development corporation for a designated area in East Birmingham, formally named the Birmingham East Mayoral Development Corporation.

Starting 11 May 2026, the Corporation functions as a statutory body under the West Midlands Combined Authority, tasked with urban development within the geographic boundaries defined by the associated official map.

The Order applies to the Secretary of State, the West Midlands Combined Authority, and any persons or entities operating within the specified development area.

Mandated a one-year notice period for new council tax premiums on second homes in specific areas following local government reorganisations.

These Regulations amend the Local Government (Structural Changes) (Finance) Regulations 2008 to clarify how new successor councils in England must implement higher council tax rates on periodically occupied dwellings.

They direct that when a new council is formed from multiple predecessor authorities, any new decision to charge higher council tax in an area where it was not previously charged is treated as a 'first determination.' This triggers a legal requirement under the Local Government Finance Act 1992 for the council to make that decision at least one year before the start of the financial year in which the higher rate takes effect.

The Order also mandates that landscape and ecological management plans for the main site construction works demonstrate a minimum of 87% biodiversity net gain using a specific metric.

These changes apply to the developers of the Longfield Solar Farm and the relevant planning authorities in Essex.
