Insurance

Definition and Core Function#

In the context of the UK built environment, insurance is defined as a contract providing financial protection against specified risks or losses. Within the cladding and external wall system (EWS) sector, this typically manifests as a suite of policies designed to mitigate the financial consequences of latent defects, professional errors, or property damage. For those managing multi-storey residential or commercial assets, insurance serves as a risk-transfer mechanism, where a premium is paid to an insurer in exchange for the insurer assuming the financial burden of defined fortuitous events.

The relevance of insurance to cladding stems from the significant capital expenditure required for remediation and the potential liabilities arising from design or installation failures. It is not a guarantee of building performance, but rather a financial instrument structured around the probability of specific adverse outcomes. In the UK, the availability and terms of insurance for buildings with complex external wall systems are heavily influenced by the historical performance of those systems and the evolving regulatory landscape.

Professional Indemnity and Public Liability#

When engaging in cladding testing, repair, or replacement, two primary forms of insurance are central to the process: Professional Indemnity (PI) and Public Liability (PL). Professional Indemnity insurance is held by consultants, surveyors, and fire engineers. It is designed to cover legal costs and damages arising from an alleged breach of professional duty, such as an incorrect assessment of a cladding material’s fire performance or a design error in a remediation scheme. For building owners, the level of PI cover held by their advisors is a critical factor in the technical due diligence process.

Public Liability insurance, conversely, is typically held by the contractors performing physical works on the building fabric. This covers claims made by third parties for incidents of bodily injury or damage to property occurring during the works. In the context of cladding replacement, where scaffolding and heavy machinery are deployed in proximity to the public and residents, PL insurance provides the necessary financial framework to address accidental damage to the building or adjacent structures.

External Wall Systems and Property Insurance#

The relationship between building fabric and property insurance—often referred to as Buildings Insurance—has become increasingly complex. Insurers assess the risk profile of a building based on the materials used in its construction, including the insulation, core material of rainscreen panels, and the presence of cavity barriers. The presence of certain combustible materials may influence the premium, the excess, or the willingness of an underwriter to provide cover at all.

For buildings undergoing remediation, insurers often require detailed technical information regarding the proposed replacement system. This data typically includes fire classifications achieved through BS EN 13501-1 testing or large-scale system tests such as BS 8414. The objective for the insurer is to quantify the risk of fire spread across the building envelope. Consequently, the insurance status of a building is often intrinsically linked to the evidence provided in an EWS1 (External Wall System) assessment or a comprehensive fire risk appraisal of external walls (FRAEW) conducted to PAS 9980 standards.

Regulatory and Process Context#

In England and Wales, the regulatory context for insurance in the cladding sector is shaped by the Building Safety Act 2022 and the subsequent changes to the Building Regulations. While the legislation focuses on safety outcomes and the identification of accountable persons, it has significant implications for the insurance market. The Act introduces new pathways for claiming costs associated with defective work, extending limitation periods for claims under the Defective Premises Act 1972.

The process of obtaining insurance for remediation projects often involves a ‘tripartite’ information flow between the building owner (or their representative), the technical consultants, and the insurance brokers. Regulators do not mandate specific insurance products, but they do require that works are carried out by competent persons. From an insurance perspective, competence is often evidenced by the ability of a firm to secure adequate PI cover. Furthermore, the UK government has occasionally engaged with the insurance industry to facilitate schemes—such as those related to professional indemnity for fire assessors—aimed at addressing market capacity issues.

Considerations for Duty Holders#

Building owners, managing agents, and directors of Right to Manage (RTM) or Residents' Management Companies (RMC) must navigate the insurance requirements of both the operational building and the remediation project. A key responsibility is the disclosure of material facts. If a building is identified as having cladding that requires remediation, this must be communicated to the building insurer. Failure to disclose such information can lead to the voiding of a policy or the rejection of a claim.

During remediation, duty holders must ensure that the "joint names" provisions are considered. This typically involves adding the building owner to the contractor’s all-risks insurance policy for the duration of the works. This protects the owner’s interest in the event of damage to the works in progress. Additionally, duty holders should verify the 'run-off' cover of their consultants; this ensures that if a firm ceases trading, insurance remains in place for a specified period to cover claims arising from work completed while they were active.

Common Misunderstandings#

A frequent misunderstanding is the belief that a valid insurance policy equates to a certification of safety or compliance. Insurance is a risk-based financial product, not a regulatory approval. A building may be insured even if it requires significant remediation, albeit potentially at a higher cost or with specific exclusions. Conversely, the fact that a building is insured does not mean the current cladding system meets contemporary Building Regulations or functional standards.

Another misconception involves the scope of 'All Risks' cover. Despite the name, these policies contain specific exclusions and conditions. In cladding projects, these might relate to specific types of hot works or the use of certain materials. Stakeholders often assume that the existence of a contractor's policy automatically protects the client from all financial loss; however, if the contractor breaches a condition of the policy—such as failing to follow agreed safety protocols—the insurer may decline the claim, leaving the liability with the contractor and potentially impacting the building owner.

Related Terminology#

Understanding insurance in the cladding sector requires familiarity with several related terms:

• Excess/Deductible: The initial amount of a claim that the policyholder must pay. In high-risk cladding scenarios, these can be substantial.
• Warranties: Often confused with insurance, a warranty is a promise that a product will perform as described, whereas insurance is a contract for indemnity against loss.
• Subrogation: The right of an insurer to pursue a third party that caused a loss to the insured, intended to recover the costs of a claim paid out.
• Material Fact: Any information that would influence the judgement of a prudent underwriter in determining the premium or whether to accept the risk.
• Exclusion: A specific provision in a policy that eliminates coverage for certain risks, such as ‘combustible cladding’ exclusions which became common in PI policies following 2017.
