The Building Safety Regulator (BSR) will formally transition from the Health and Safety Executive (HSE) to a new independent executive non departmental public body on 27 January 2026. This change is enacted by the Building Safety Regulator (Establishment of New Body and Transfer of Functions etc.) Regulations 2026 which were made on 7 January. The reform implements key recommendations from the Grenfell Tower Inquiry, aiming to strengthen accountability and create clearer oversight of building safety. 

What is changing?

New Independent Regulator

The BSR becomes a standalone body corporate, sponsored by the Ministry of Housing, Communities and Local Government (MHCLG). The new regulator will have the power to: 

• Enforce building safety laws and bring legal proceedings
• Charge for advice and services
• Enter contracts, employ staff, borrow funds, and receive government grants 

Transfer of functions

All building safety functions under the Building Safety Act 2022 will move from the HSE to the BSR. The shift is intended to consolidate regulatory responsibility and enhance focus on building safety. 

Governance structure

The BSR will be led by a chair and 3-8 board members appointed by the Secretary of State, plus a chief executive. The board may establish committees and sub committees to support operational delivery. 

Ongoing case management and support

The HSE will continue to support the BSR until December 2026, ensuring a managed handover.

All existing Gateway 2 and Gateway 3 building applications will transfer to the new regulator. 

Reporting obligations

The BSR must publish an Annual Report after each financial year, with its first financial year running from 27 January to 31 March 2026. 

Why it matters 

Greater regulatory clarity and accountability 

The new structure is intended to streamline decision making, centralise oversight, and improve transparency across the construction lifecycle. 

With dedicated statutory powers and independence from the HSE, the BSR is expected to take a more assertive enforcement approach aligned with post Grenfell expectations. 

Practical implications

• Dutyholders should anticipate more targeted regulatory engagement.
• New fee charging powers may affect project cost planning.
• Transitional arrangements mean current applications will continue without interruption, but oversight may become more stringent as the BSR matures.

To ensure alignment with BSR expectations, those affected should review ongoing and planned projects, and prepare for increased scrutiny, particularly in relation to high rise and higher risk buildings.
