The Building Safety Regulator (BSR) has announced that it expects to conclude decisions on all but three of the 91 legacy Gateway 2 applications by the end of the year. These applications, which relate to 21,745 units caught under the previous regulatory regime before assessment processes were overhauled in the summer, represent a significant backlog the regulator is working to clear. According to the BSR, 88 of these schemes will be resolved within the year, with the remaining three expected to be decided by January, subject to ongoing progress and timely information provision by applicants.

The regulator’s latest data, as of 1 October, shows that 152 new Gateway 2 applications are currently in the system, covering 33,670 units alongside a further 253 remediation applications affecting 22,304 units. London leads with 200 Gateway 2 applications, with the rest of England accounting for 175. BSR chair Andy Roe, who has held the role since July, outlined efforts to accelerate the approval process, including batching applications, introducing account managers for major developers, and upgrading IT infrastructure. Notably, the average waiting time for Gateway 2 approval across the UK stands at 43 weeks, rising to 48 weeks in London, reflecting ongoing capacity and complexity challenges.

Despite progress, the regulator acknowledges several obstacles remain, including multiple ‘blockers’ in many cases, ranging from staff availability to the need for detailed technical information. A particular bottleneck is the scarcity of expertise in computational fluid dynamics — crucial for evaluating fire safety strategies in high-rise residential buildings. This shortage limits the speed at which complex safety decisions can be finalised.

In response to these challenges and the urgent need to support housing delivery, the UK government recently announced reforms to the BSR designed to accelerate housebuilding. These reforms include a new Fast Track Process aimed at speeding up the review of new build applications and reducing delays, ultimately boosting confidence in the sector. The changes align with recommendations from the Grenfell Tower Inquiry and intend to pave the way for a single construction regulator to oversee building safety and quality.

Further government data underscores the broader landscape of building safety remediation efforts. Monthly updates reveal ongoing activity in the remediation of unsafe cladding, with 64% of buildings applying for funding having started or completed remediation and 82% having formal remediation plans in place. By the end of the 2024-25 period, over 1,600 buildings had been remediated, representing about one-third of all identified buildings requiring attention. Yet, reports also highlight risks that the current system may struggle to cope with increasing demands, prompting additional measures to enhance operational capacity.

The BSR has made strides in streamlining processes for higher-risk buildings, reducing the average Gateway 2 decision time from up to 48 weeks to around 16 to 18 weeks in some cases. This improvement is supported by updated guidance and closer industry collaboration to improve application quality and reduce delays. However, the regulator’s timeline for clearing legacy applications—and advancing remediation work—remains contingent on overcoming persistent staffing, technical, and procedural hurdles.

In summary, while the BSR is demonstrating clear progress in addressing its legacy application backlog and implementing reforms to quicken approvals, significant challenges remain. The agency’s ability to maintain its projected timetable will rely heavily on enhanced resource availability, industry cooperation, and continued government support to meet housing safety and delivery goals.
