Code compliance on the UK construction

Building Safety Act 2022, with the Building (Higher-Risk Buildings Procedures) (England) Regulations 2023 (SI 2023/909) and the Building Regulations etc. (Amendment) (England) Regulations 2023 (SI 2023/911)

UK Parliament and MHCLG (legislation.gov.uk, gov.uk, HSE Building Safety Regulator)

Load-bearing for any residential work above 18m and increasingly for competence and duty-holder requirements on all buildings. The gateways are hard stops, which makes them programme risks rather than approvals.

New Roads and Street Works Act 1991 (notably s.50), with permit schemes made under the Traffic Management Act 2004

UK Parliament / Department for Transport / individual highway authorities

Urban UK sites routinely lose weeks here. The lead times belong in the programme as constraints, and they must be researched per authority.

Party Wall etc. Act 1996

UK Parliament / MHCLG

On any urban infill or basement job these notice periods control the start date, and they are commonly discovered after the programme has been issued.

The Building Regulations 2010 and the Approved Documents (Parts A to S)

UK Government / HSE Building Safety Regulator

Town and Country Planning Act 1990 (including Schedule 7A inserted by the Environment Act 2021), Community Infrastructure Levy Regulations 2010 as amended, and the statutory biodiversity metric

UK Parliament / MHCLG / Natural England

These are the consents that most often control a UK start date and they sit outside building control entirely, so a programme built only around building regulations approval will miss them.

NHBC Standards

NHBC (with equivalent regimes from LABC Warranty, Premier Guarantee and Checkmate)

UK new homes are effectively unsaleable and unmortgageable without a warranty, so the warranty provider's standards operate as a second, often stricter, code alongside the Building Regulations.
