BSR Approvals Are Speeding Up — But Gateway Three Looms

11 August 2026 · 4 min read · Regulatory Update

The Building Safety Regulator has published its latest transparency data to 1 August 2026 — and the numbers tell a story of genuine progress at gateway two, paired with an uncomfortable question no one in the residential sector can afford to ignore: what happens at gateway three?

Where We Are: Gateway Two Is Moving

The headline figures are encouraging. Over the last 12 weeks, the BSR made 349 building control decisions across all higher-risk building categories, with an overall national approval rate of 82%. For new higher-risk buildings and conversions, the approval rate reached 91% — a dramatic improvement from 39% a year ago. Median approval times have nearly halved, from 43 weeks to 22 weeks.

This is not cosmetic. The BSR's Innovation Unit, established in August 2025, has driven much of the improvement through streamlined assessment processes and closer engagement with applicants. The regulator is also managing 131 live new-build applications representing over 30,000 residential units — a substantial pipeline that was previously stalled.

The Problem: Gateway Three Is Untested

Gateway three is the final approval stage — the pre-occupation check that a building has been built as designed and is safe for residents. Despite the improving picture at gateway two, no new-build developments have yet reached gateway three. The first schemes are approaching, and the industry is right to be cautious.

The fundamental shift is this: under the Building Safety Act, iterative design changes between gateway two and gateway three are not an option. If the principal contractor deviates from the approved design, the developer faces a return to gateway two — with the associated delay, cost, and uncertainty. The golden thread of information is no longer aspirational — it is a condition precedent to occupation.

This creates a chain of risk. Who carries the cost of a gateway three rejection? If the principal contractor has altered specifications, the contractor may be liable. But if the root cause is inadequate design-stage information or poor coordination between designer and contractor, the position is less clear. Developers and their QS teams need to address this allocation of risk upfront, through contract terms, LADs holidays, or early handover arrangements — not after the problem materialises.

Approved Document B: Another September Deadline

The gateway three conversation intersects with another imminent change. From September 2026, updated Approved Document B guidance will require more than one common stair in blocks of flats with a storey at 18 metres or above, alongside provisions for evacuation lifts. For schemes currently at gateway two or early construction, this may necessitate design revisions — which, under the new regime, are far from straightforward.

Separately, the government is consulting on reforms to simplify maintenance and repair work in existing higher-risk buildings, with proposals to exclude small-scale work (undertaken by three or fewer people within five working days, not impacting fire safety) from the Category A approval route. That consultation closes on 3 September 2026.

What This Means in Practice

1. Don't assume gateway two clearance is the finish line. The real compliance hurdle is gateway three. Appoint a named person accountable for golden thread maintenance from day one of construction — not when the completion certificate is due.
2. Lock down design early. Every design change post-gateway two is a risk. If your project team is accustomed to value engineering through construction, that process now needs BSR sign-off or must happen before gateway two submission.
3. Allocate risk in your contracts. Ensure your building contract and professional appointments clearly set out responsibility for gateway three evidence. Principal designers and principal contractors should have explicit obligations around the golden thread — and the cost of failing to provide it.
4. Check your Approved Document B position. If your residential scheme is over 18 metres and you haven't accounted for second staircases, act now. Design changes post-submission will be costly and time-consuming under the BSR regime.
5. Cost the delay. A gateway three rejection doesn't just mean rework — it means unoccupied units, holding costs, and potentially breach of sale contracts. Factor this into your development appraisal as a quantifiable risk, not an unknown.

The BSR has proven it can unblock gateway two. The sector should take that as a warning, not a comfort. The regulator will apply the same rigour at gateway three — and there, the consequences of non-compliance are felt at completion, not at planning stage.
