Section 106 statutory and data changelog

Building Safety Levy in force. It applies to building-control applications for major residential development in England submitted on or after today: at least 10 dwellings, or at least 30 bedspaces in purpose-built student accommodation (a net increase of 10 or 30 where the building already contains either). Rates are per sqm of chargeable GIA, set per local-authority area in Schedule 3, with previously developed land at half rate. The Building Safety Levy (Amendment) (England) Regulations 2026 (SI 2026/1034) came into force the same day and widened what counts as previously developed land. The levy is a parallel charge: reg 122 and the per-head structure of s.106 are unchanged. See /regulation/building-safety-levy. [Building Safety Levy (Amendment) (England) Regs 2026 (SI 2026/1034)]

NPPF rewritten and republished. It replaces the Dec 2024 Framework, splits policies into plan-making and decision-making, drops the numbered paragraphs, and moves viability into decision-making Policy DM5, so the old paragraph 58 no longer exists. The reg 122 necessity test and the per-head structure of s.106 contributions are unchanged. See /regulation/nppf-dec-2024. [NPPF (Aug 2026)]

BNG amendment regulations laid (SI 2026/790): a 0.2ha small-site exemption, removal of the self and custom-build exemption, and a relaxed gain hierarchy for non-major development, all for applications submitted on or after 6 Aug 2026. See /bng/exemptions-2026. [Biodiversity Gain (T&CP) (Amendments and Transitional Provisions) (England) Regs 2026 (SI 2026/790)]
