What Does the BSR’s Remediation Improvement Plan Mean for Building Safety Professionals?

If you work anywhere near the building safety space in England, you’ll know that the remediation of higher-risk buildings has become one of the most pressing (and frustrating) challenges in the sector. Almost nine years after the Grenfell Tower tragedy, thousands of residents still live in buildings with unsafe cladding, and the regulatory process meant to fix the problem has been struggling under its own weight.

That’s why the Building Safety Regulator’s (BSR) newly published external remediation improvement plan deserves close attention. It represents the most significant operational reset of the remediation approval process since the BSR was established under the Building Safety Act 2022.

Why Has the BSR Launched a Remediation Improvement Plan?

The plan addresses a specific bottleneck: external remediation applications for higher-risk buildings (HRBs) in England have been taking far too long to process. Average determination times have been running at around 18 weeks or more, well above the statutory target of eight weeks. Older, more complex cases have fared even worse.

The causes are a combination of internal resource constraints within BSR, a backlog of non-compliant legacy submissions, and the sheer complexity of remediation work on existing occupied buildings. Around 40% of live remediation applications also rely on government funding, which adds another layer of coordination.

In January 2026, the BSR formally transitioned from sitting within the Health and Safety Executive (HSE) to become a standalone arm’s-length public body, sponsored by the Ministry of Housing, Communities and Local Government (MHCLG). That move, itself a key recommendation from the Grenfell Tower Inquiry, was designed to give the regulator sharper focus and clearer accountability. The remediation improvement plan is, in many ways, the first major test of whether that independence can translate into faster, more effective outcomes.

What Is Actually Changing Under the New Plan?

The improvement plan introduces several practical measures. A dedicated external remediation multidisciplinary team (MDT) will be established, modelled on the BSR’s Innovation Unit, which has already shown success in processing new-build applications since late 2025. This team will be backed by dedicated account managers to handle applicant communications, freeing up technical regulatory leads to focus on the work that only they can legally carry out.

A recruitment drive is also underway to reduce individual caseloads for regulatory leads from an average of 25 down to around 10. That is a significant shift in capacity, and if delivered, it should make a real difference to turnaround times.

Perhaps the most notable change is the introduction of ‘approval with requirements’. This mechanism allows projects to start safely while distinct technical issues are resolved in parallel, rather than holding everything up until every last detail is signed off.

The BSR is also committing to more direct engagement with applicants. That means face-to-face or virtual meetings for complex projects, rather than relying solely on written correspondence. It’s a simple change, but one that industry has been calling for. In my experience, most technical disputes are resolved far quicker through conversation than through chains of emails and document revisions.

Why Are Incomplete Submissions Still Causing So Many Delays?

This is the uncomfortable part of the conversation, and it’s one the industry needs to own. The BSR has been clear that a significant proportion of delays are caused by applicants submitting incomplete or non-compliant documentation. The list of common failings is actually very startling: insufficient evidence of fire-resistant properties for replacement materials, missing structural loading calculations, inadequate cavity ventilation assessments, and incomplete thermal performance data.

Aside from the technical deficiencies, the BSR has also flagged applications that rely on vague statements of future intent rather than finalised design information, unsupported ‘non-worsening’ claims with no comparative analysis, and poorly organised document packs that make it difficult for assessors to even navigate the submission.

I’ve spent nearly four decades in the health and safety sector, and a consistent truth across every compliance regime I’ve encountered is this: the quality of what you put in determines the speed of what comes out. If your remediation application lands on a regulator’s desk with missing fire test evidence or no structural calculations, it isn’t going to be fast-tracked. It’s going back to the bottom of the pile. Getting the submission right first time is the single most effective thing an applicant can do to reduce delays.

How Does This Fit into the Wider Building Safety Picture?

At the end of February 2026, some 4,310 residential buildings of 11 metres and above had been identified nationally with unsafe cladding. Just over half had undergone some form of remediation, and only around 35% had completed works entirely. With the government’s 2029 deadline for landlords to either remediate or set a completion date for all affected buildings, time is only getting shorter.

The BSR has set itself a target of reducing average decision times for remediation applications to under 12 weeks by December 2026, with approval rates above 65%. That 12-week figure is still above the statutory eight-week milestone, but it would be a marked improvement on where things stand now. The regulator also aims to bring its live remediation caseload down to a steady 80 to 100 cases by September 2026.

It’s worth acknowledging what this plan represents within the broader trajectory of post-Grenfell reform. The BSR’s strategic plan for 2026–27 identifies five priority areas, and remediation is front and centre. The Building Safety Levy comes into effect in October 2026. The single construction regulator, which the BSR is intended to evolve into, is being actively shaped.

What Should Health and Safety Professionals Be Doing Now?

For those involved in building safety, whether you’re a fire engineer, a building manager, a principal accountable person, or an OSH consultant working in construction, there are some practical steps worth prioritising.

• Audit your current remediation submissions. If you have live applications with the BSR, review them against the common failure points identified in the plan. Missing fire test evidence, absent structural calculations, and poorly organised documents are all fixable before the regulator has to ask for them.
• Invest in submission quality upfront. Engage fire engineers, facade specialists, and structural engineers early enough that their evidence packages are finalised before you submit, not promised for later.
• Prepare for closer regulatory engagement. The BSR’s shift towards direct meetings and account management means your team needs to be ready for more interactive, less paper-based exchanges. That’s a good thing, but it requires preparation.
• Understand the prioritisation structure. The BSR is developing a published prioritisation framework for external remediation. Knowing where your building sits in that structure will help you plan realistic timelines and manage stakeholder expectations.
• Stay current with BSR guidance. The regulator has committed to publishing further remediation-specific guidance and digital tracking tools over the coming months. Monitor these closely; they’ll directly affect how applications are assessed and progressed.

The remediation improvement plan is a necessary and overdue step. It won’t solve everything overnight, and the targets the BSR has set itself are ambitious given the scale of the backlog. But the direction is right: more capacity, clearer processes, better engagement, and a firm expectation that the industry raises the standard of its submissions. For health and safety professionals working in this space. Prepare well, submit well, and engage early.
