Regulatory

The Definition of Regulatory in the External Wall Context#

In the UK built environment, the term ‘regulatory’ refers to any matter pertaining to rules, standards, or laws established by a statutory authority. Within the cladding and external wall sector, this primarily concerns the legal frameworks governing the design, installation, maintenance, and remediation of building envelopes. It encompasses both primary legislation, such as the Building Act 1984 and the Building Safety Act 2022, and secondary legislation, including the Building Regulations 2010.

The regulatory landscape serves to define the minimum standards for performance, durability, and safety. For external wall systems, these standards address a variety of factors including structural integrity, thermal performance, moisture resistance, and fire safety. A regulatory requirement is not a suggestion or a best-practice guideline; it is a compulsory obligation that must be met to ensure legal compliance. Failure to adhere to these mandates can result in enforcement action, the inability to secure insurance, or challenges in property transactions.

Application in Cladding Testing and Remediation#

The term ‘regulatory’ is frequently invoked during the assessment of existing buildings. When a chartered engineer or qualified fire surveyor conducts an external wall survey, such as an EWS1 (External Wall System) assessment or a Fire Risk Appraisal of External Walls (FRAEW) under PAS 9980, they are operating within a regulatory framework. The purpose of such testing is often to determine whether the existing materials and construction methods align with the standards applicable at the time of construction or the heightened requirements introduced by recent legislative updates.

In the context of remediation, regulatory oversight ensures that any replacement cladding or insulation meets current performance specifications. For example, the ‘regulatory ban’ on combustible materials, introduced in 2018 and subsequently updated, dictates the types of materials permitted on the external walls of specific building types over a certain height. During repair or replacement work, the regulatory process involves notifying Building Control bodies, who inspect the work to verify that it conforms to the Approved Documents, which provide practical guidance on meeting the requirements of the Building Regulations.

Relationship to Building Fabric and External Wall Systems#

The regulatory status of a building fabric is determined by how its individual components—including the outer rainscreen, insulation, cavity barriers, and sub-structure—interact as a complete system. Regulations often specify performance criteria for the system as a whole rather than just individual products. This is particularly relevant in the context of ‘Regulation 7’, which requires that building work be carried out with adequate and proper materials and in a workmanlike manner.

External wall systems must also adhere to regulatory standards regarding thermal bridging and ventilation. In the UK, the regulatory drive toward ‘Net Zero’ has increased the stringency of thermal requirements, meaning that cladding replacements often involve a regulatory obligation to improve the building’s U-value (thermal transmittance) beyond its original design specification.

General Regulatory Context in England and Wales#

The regulatory environment in England and Wales has undergone significant transformation, particularly following the introduction of the Building Safety Act 2022. This legislation created the Building Safety Regulator (BSR) under the Health and Safety Executive (HSE). For ‘higher-risk buildings’—typically those at least 18 metres in height or at least seven storeys—the regulatory process is now more rigorous, involving specific ‘gateways’ during the design and construction phases.

For existing buildings, the regulatory focus has shifted toward the ‘Golden Thread’ of information. This is a digital record of the building’s design, construction, and ongoing management, intended to ensure that the regulatory history of the external wall system is transparent and accessible. The regulatory burden has also increased for ‘Accountable Persons’ and ‘Principal Accountable Persons,’ who are legally responsible for assessing and managing building safety risks. While the underlying Building Regulations provide the technical benchmarks, the new legislative framework provides the enforcement mechanisms to ensure these benchmarks are consistently achieved.

Obligations for Building Owners and Managers#

Directors of Residents’ Management Companies (RMCs), Right to Manage (RTM) companies, and professional managing agents must navigate a complex web of regulatory duties. A central requirement is ensuring that the building has a valid fire risk assessment that accounts for the external wall system. Under the Fire Safety Act 2021, the regulatory scope of the Regulatory Reform (Fire Safety) Order 2005 was clarified to explicitly include the building’s structure, external walls, and any common parts.

Understanding the regulatory status of a building is also essential for financial management. Many government funding schemes for cladding remediation, such as the Building Safety Fund or the Cladding Safety Scheme, are predicated on the building meeting specific regulatory criteria regarding height and the presence of certain materials. Building owners must also ensure that any professionals engaged for testing or remediation are competent to operate within this regulatory environment, as the ultimate legal responsibility for compliance often rests with the building owner or the designated Accountable Person.

Common Misunderstandings#

A frequent misunderstanding is the distinction between ‘regulatory compliance’ and ‘guidance.’ While the Approved Documents provide a common path to compliance, they are not the law itself; they are guidance on how to meet the requirements of the Building Regulations. A building may, in theory, achieve regulatory compliance through alternative means, provided those means can be proven to meet the functional requirements of the law. However, in the cladding industry, following the Approved Documents is the standard method for demonstrating compliance.

Another misconception is that regulatory requirements only apply at the time of construction. In reality, changes in legislation can impose new duties on existing buildings. For instance, the requirement to conduct an FRAEW may apply to a building that was considered compliant at the time it was built. Furthermore, ‘regulatory’ is often confused with ‘insurable.’ While insurers often require buildings to meet regulatory standards, they may also impose additional requirements that go beyond the statutory minimums to mitigate their own financial risk.

Closely Related Terminology#

To understand the term ‘regulatory’ fully, it is necessary to distinguish it from several related concepts:

• Statutory: This refers specifically to laws enacted by Parliament (Acts). All regulatory requirements are statutory, but not all statutory requirements are necessarily technical building regulations.
• Compliance: This is the state of meeting the regulatory requirements. A building is ‘compliant’ when it satisfies all relevant laws and standards.
• Non-compliance: The failure to meet regulatory standards. This may be due to the use of prohibited materials, poor installation, or a lack of required documentation.
• Enforcement: The process by which authorities, such as the Building Safety Regulator or Local Authority Building Control, ensure that regulatory requirements are met, potentially using legal notices or prosecution.
• Competence: In a regulatory context, this refers to the specific combination of skills, knowledge, experience, and behaviours required by professionals to perform work that aligns with the law.
