Commercial landlords are being told they need everything from comprehensive compartmentation surveys to gold-plated fire stopping upgrades. Separating genuine regulatory requirements from over-specification requires technical knowledge most building owners don’t possess. The confusion has intensified in 2026 as the Building Safety Act creates new duty holder obligations that overlap with existing fire safety regulations, whilst contractors of varying competence make contradictory claims about what compliance actually requires for your specific building type and use.

If you’re responsible for a commercial property, understanding your legal obligations isn’t optional. This article clarifies the five specific passive fire protection requirements you must meet under current regulations, cutting through the complexity to explain what’s genuinely mandatory for your building.

1. Compartmentation Integrity Maintenance

All commercial buildings must maintain the compartmentation integrity that was designed into the original construction. This means fire-rated walls, floors, and ceilings must continue to provide their intended fire resistance despite subsequent alterations for services, refurbishments, or tenant fit-outs.

Every penetration through fire-rated structures requires proper attention. Cables, pipes, ducts, and conduits that pass through compartment walls or floors must be sealed with appropriately tested and certified fire-stopping products that restore the fire resistance rating of the barrier. The responsibility sits with you as the building owner, regardless of who created the penetrations.

If your tenant’s contractor installed air conditioning pipework through a fire-rated wall without proper fire stopping, you’re liable for the compartmentation failure. This isn’t a hypothetical risk, building control can serve enforcement notices requiring retrospective surveys and remediation if compartmentation integrity cannot be demonstrated, with costs falling entirely on you as the duty holder.

The practical implication: when you commission works or approve tenant alterations, ensure fire-rated structures are identified beforehand and that any necessary penetrations are sealed by competent contractors using certified products. Retrospective surveys across entire buildings cost substantially more than getting it right first time.

2. Competent Person Certification

The Building Safety Act 2026 explicitly requires that passive fire protection works are installed by competent persons and that installations are certified by recognised third-party schemes. This ends the era when any general builder could claim fire stopping competence without independent verification.

For commercial buildings, this means remedial works or new installations must be carried out by contractors with FIRAS accreditation or equivalent third-party certification. You must retain documentary evidence of their competence and the specific product certifications for every application. Generic statements that ‘fire stopping has been completed’ no longer satisfy regulatory or insurance requirements.

Insurance policies increasingly include clauses excluding fire damage claims where passive fire protection wasn’t installed by accredited contractors or used tested product combinations. This makes competent person certification a financial requirement, not merely a regulatory box-ticking exercise. When purchasing commercial property or refinancing, lenders now routinely request evidence that passive fire protection meets competent person standards. Uncertified works can affect property values and transaction viability.

Ask any contractor quoting for fire protection services to provide their FIRAS certificate or equivalent third-party accreditation before accepting proposals. If previous owners or contractors cannot provide certification for existing works, budget for re-inspection and potential remedial installations by accredited specialists.

3. Periodic Inspection and Documentation

Commercial building owners must demonstrate ongoing compliance with fire safety regulations through periodic inspection regimes. For passive fire protection, this means annual or biennial surveys, depending on building complexity and use intensity.

The inspections must verify that compartmentation remains intact despite ongoing maintenance, tenant alterations, or building system upgrades. They must be conducted by competent surveyors who can identify defects and assess whether remediation is required. Visual inspections of ceiling voids, service risers, and penetrations through fire-rated structures form the core of these surveys.

You must retain a golden thread of documentation showing initial compliance certification, all subsequent inspection reports, any remedial works undertaken, and evidence that identified defects have been addressed. Building control and fire service inspections will specifically request this documentation chain. Missing links in your compliance history create regulatory vulnerability and complicate property transactions.

For buildings with multiple commercial tenants, your lease agreements should explicitly prohibit tenants from creating penetrations through fire-rated structures without your prior approval and certification by accredited contractors. You cannot delegate your duty holder obligations even though you don’t directly control tenant alterations. The legal responsibility remains with you as the building owner.

Establish a compliance file for each property containing original fire safety certificates, all inspection reports, remedial works certificates, and correspondence with building control. This becomes your evidence base if regulatory questions arise or if you sell the property.

4. Fire Risk Assessment Integration

Your building’s fire risk assessment must explicitly address passive fire protection adequacy. Where compartmentation defects are identified, you must demonstrate that reasonable steps are being taken to remediate within appropriate timeframes based on risk severity.

This doesn’t necessarily mean immediate remediation of every defect. Phased approaches are acceptable where life safety priorities are addressed first, but you need documented action plans with realistic completion dates and evidence of progression. Regulatory authorities assess reasonableness based on risk severity, available resources, and demonstrated commitment to resolution.

Fire risk assessors are increasingly recommending compartmentation surveys as part of their assessment process when buildings have undergone significant alterations or when visual inspections reveal potential defects. Ignoring these recommendations creates indefensible positions if subsequent incidents occur.

The courts have established that building owners who commissioned fire risk assessments identifying compartmentation concerns but took no action face potential corporate manslaughter liability if fire spreads through unsealed penetrations. This makes integration between fire risk assessment and passive fire protection compliance a legal imperative, not administrative nicety.

When your fire risk assessment recommends a compartmentation survey, commission it promptly and ensure the findings are appended to your fire risk assessment documentation. This demonstrates you’re taking reasonable steps to understand and address risks, which provides substantial legal protection even whilst remedial works are being planned or phased.

5. Insurance Disclosure and Evidence

Commercial building insurance policies now routinely require disclosure of any known passive fire protection defects and may condition coverage on remediation within specified timeframes or implementation of temporary risk mitigation measures.

When your survey identifies compartmentation failures, you must notify your insurer within the disclosure period specified in your policy, typically 14 to 30 days. Failure to disclose can void coverage entirely if fire damage subsequently occurs. This isn’t theoretical. Insurers are actively declining claims where policy holders failed to disclose known defects identified in surveys or fire risk assessments.

Insurers are requiring certification evidence that passive fire protection meets current standards as a condition of policy renewal, particularly for older buildings where original construction predated current Building Regulations. Renewal questionnaires now commonly ask specific questions about compartmentation surveys, identified defects, and remediation timescales.

For landlords with mortgaged properties, your lender’s interest is noted on insurance policies. Insurers who withdraw or restrict coverage due to passive fire protection defects will notify your lender, potentially triggering loan review or demands for immediate remediation as a condition of maintaining financing. The financial implications extend beyond insurance premiums to the viability of your property financing arrangements.

Maintain open communication with your insurance broker about compliance status. Provide copies of survey reports, remediation plans, and completion certificates as they become available. Brokers can often negotiate continued coverage with specific endorsements whilst remedial works proceed, provided you demonstrate a genuine commitment to resolution.

How to Verify Your Compliance Position

Commission a passive fire protection survey from a FIRAS-accredited contractor who can assess compartmentation integrity against current Building Regulations and identify any defects requiring remediation. This creates the defensible evidence base required to demonstrate reasonable steps to regulatory authorities, insurers, and lenders.

Review your building insurance policy specifically for passive fire protection clauses and disclosure requirements. Ensure your broker receives copies of survey reports and remediation plans within required timeframes to maintain coverage. Don’t assume your broker knows about surveys you’ve commissioned unless you explicitly provide the documentation.

Audit your documentation to verify you hold competent person certificates for any passive fire protection works undertaken since you acquired the building. If previous owners or contractors cannot provide certification, budget for re-inspection and potential remedial works by accredited specialists. Gaps in certification history create transaction problems when selling or refinancing.

Establish whether your fire risk assessment explicitly addresses compartmentation adequacy or simply makes general statements about fire safety. If necessary, commission a specialist passive fire protection survey that can be appended to your fire risk assessment to demonstrate comprehensive compliance documentation.

How TBL Fire Protection Closes the Gap

Fire barriers and fire boarding

TBL Fire Protection conducts compliance audits for commercial landlords that assess your current position against all five regulatory requirements, identifying gaps and providing prioritised action plans that demonstrate reasonable steps within realistic budgets. Our surveys don’t over-specify. We distinguish between mandatory regulatory requirements and recommended improvements, giving you the information to make informed decisions about scope and phasing.

We provide the competent person certifications and third-party accreditation documentation that satisfies insurance requirements and building control inspections. This eliminates the risk that your passive fire protection works are challenged for lack of proper certification. Our FIRAS accreditation means the work we complete meets the competent person standards that insurers and lenders now demand as a condition of coverage and financing.

Our survey reports are structured to integrate directly with fire risk assessments, providing the technical evidence that fire risk assessors need to close compartmentation concerns without requiring separate consultant engagement. This coordinated approach reduces costs and ensures your compliance documentation forms a coherent whole rather than disconnected reports that don’t speak to each other.

We coordinate with building control before and during remedial works to ensure our certification approach satisfies their specific evidence requirements. This prevents situations where completed works are rejected for documentation deficiencies that could have been avoided through upfront liaison. We know what building control officers need to see because we work with them regularly across the Midlands.

Take Control of Your Compliance Position

Meeting passive fire protection obligations as a commercial landlord in 2026 requires more than fixing visible defects. It demands comprehensive compliance across certification, documentation, inspection, and insurance dimensions that many building owners don’t fully understand until regulatory or coverage problems emerge.

Waiting for an enforcement notice, insurance renewal crisis, or transaction complication to discover compliance gaps puts you in reactive crisis management mode, where options are limited, and costs escalate. Taking proactive steps now to understand your compliance position gives you control over timescales, budgets, and priorities.

TBL Fire Protection offers compliance audits for commercial landlords across the Midlands who want definitive answers about whether their buildings meet current passive fire protection requirements and what specific steps are necessary to close any gaps. Our assessments provide clarity and defensible compliance positions before regulatory inspections or insurance renewals force reactive crisis management.
