Latest Build UK Building Safety Regime explainer published

Build UK published its latest updated guide to the Building Safety Regime for July 2025. This update follows a number of previous versions, which have aimed to capture succinctly some of the key elements of the building safety regime and record significant changes as and when they happen. The guide is endorsed by the Construction Leadership Council(CLC), explaining relevant bodies, responsibilities, competence, and existing legislation reforms related to building safety, as well as activities outside the scope of the Act but still relevant to building safety.

Build UK originally published its Guide to Building Safety Regime in July 2023 to help businesses in the construction sector understand the upcoming Building Safety Act regulations and their responsibilities. The same guide has been updated at various points in time in line with changes, the first update being in October 2023 with links to the most recent guidance, including Safety Case for a High-Rise Residential Building and Preparing a Safety Case Report, and then a second update in November 2023 including information on higher-risk buildings, building control processes, remediation orders, and transitional arrangements for the second staircase.

The 2025 update to the Build UK Building Safety Regime explainer, as before, includes updates to:

• The new bodies providing oversight of the regime: the Building Safety Regulator, the National Regulator for Construction, and the New Homes Ombudsman.
• The responsibilities associated with accountable persons, building owners, landlords, developers, and duty holders.
• The systems introduced, such as building control as a regulated profession, competency requirements of individuals and the demonstrated organisational capability of organisations, gateways or decision points at the three key stages of a higher-risk building, and the golden thread of information, stored electronically and updated, as well as mandatory occurrence reporting.
• Existing legislation such as Approved Document B of the Building Regulations as updated, the Architects Act as amended, the Building Act with Section 38 brought into force, Building Liability Orders, the Defective Premises Act, and the strengthening of Fire Safety Orders.
• It also covers activities outside the scope of the Act, such as cladding remediation programs, the External Wall System (EWS1), and the Mayor of London's Building Safety Standards, with their higher standard of safety for new buildings in London.
