Meet Modern

Definition and Technical Scope#

In the context of the UK built environment, the term "meet modern" refers to the requirement for a building’s external wall system or specific cladding components to satisfy current construction standards, performance criteria, and statutory requirements. It is a phrase frequently utilised by surveyors, fire engineers, and façade consultants when evaluating the gap between a building’s original design intent and the prevailing regulatory expectations at the time of assessment.

To meet modern standards does not merely imply a like-for-like replacement of aged components. Instead, it signifies that any remediation or new installation must align with the most recent iterations of the Building Regulations, associated Approved Documents, and industry-standard testing protocols. In the cladding sector, this typically focuses on fire performance, thermal efficiency, moisture management, and structural integrity. The term acknowledges the evolutionary nature of construction law, where the benchmark for "compliance" is a moving target influenced by technical advancements and legislative updates.

Application in Cladding Testing and Remediation#

The term "meet modern" frequently arises during the assessment phase of an External Wall System (EWS) survey. When a building undergoes a technical audit—such as an EWS1 assessment or a PAS 9980 appraisal—the primary objective is to determine if the existing assembly poses an unacceptable risk. If the system is found to be deficient by contemporary standards, the remediation strategy is designed to ensure the building will "meet modern" requirements upon completion.

In practical terms, this often involves the replacement of combustible insulation or rainscreen panels with non-combustible alternatives that achieve a European Classification (Euroclass) of A1 or A2-s1, d0. However, meeting modern standards also extends to the "hidden" elements of the façade, such as cavity barriers, fire stopping, and the mechanical fixings used to secure the system. A remediation project is generally considered successful only when a competent professional can certify that the entirety of the external wall assembly adheres to the current version of Approved Document B (Fire Safety) and Approved Document L (Conservation of fuel and power).

External Wall Systems and Building Fabric#

The relationship between the term "meet modern" and the building fabric is holistic. It is a common misconception that meeting modern standards only concerns the outermost layer of a building. In reality, the external wall system is treated as a single, integrated assembly. For a building to meet modern requirements, the interaction between the substrate, the insulation, the vapour membrane, the cavity, and the cladding must be technically sound.

When a building is updated to meet modern standards, the process often necessitates a re-evaluation of the building’s thermal envelope. Improvements in fire safety must be balanced with the requirement for increased airtightness and thermal resistance. This multidisciplinary approach ensures that the building fabric performs predictably over its remaining lifecycle, adhering to the standard of care expected in current professional practice.

Regulatory and Process Context#

The regulatory landscape in England and Wales has undergone significant transformation, particularly following the introduction of the Building Safety Act 2022. The concept of meeting modern standards is now inextricably linked to the "Gateways" process for higher-risk buildings (HRBs). Under this framework, the Building Safety Regulator (BSR) oversees the design and construction phases to ensure that works are carried out to current specifications.

In a general sense, the requirement to meet modern standards is triggered whenever "material effect" works are undertaken. If a cladding system is being replaced, the new system must usually comply with the regulations in force at the start of the work, rather than the regulations that existed when the building was first constructed. This retrospective application of heightened standards is a core component of the UK’s drive to improve the safety and sustainability of the existing high-rise stock. Professionals must navigate various codes of practice, such as British Standards (BS 8414 for large-scale fire testing) and the RICS guidance notes, to verify that the proposed works will indeed meet modern expectations.

Implications for Building Management#

For building owners, managing agents, and directors of Right to Manage (RTM) or Residents' Management Companies (RMC), the necessity to meet modern standards represents a significant technical and financial consideration. It is often the pivot point around which insurance premiums, mortgageability, and property valuations revolve. When a building is described as failing to meet modern standards, it implies a level of obsolescence that may require capital expenditure to rectify.

Directors must understand that "meeting modern" is not a voluntary upgrade but often a necessity for securing an EWS1 form with a satisfactory rating (such as A1, A2, or B1). Decisions regarding remediation must be informed by qualified façade engineers who can articulate how the proposed works will bridge the gap between the building’s current state and the statutory benchmarks. It is also important to note that the process involves rigorous documentation, often referred to as the "Golden Thread" of information, which proves that the materials and methods used actually satisfy the modern criteria.

Common Misunderstandings#

A frequent misunderstanding is that a building constructed ten or fifteen years ago automatically meets modern standards because it was compliant with the regulations at the time of its completion. However, regulatory requirements—particularly regarding the combustibility of materials on buildings over 11 or 18 metres—have changed substantially. A system that was considered compliant in 2010 may not meet modern safety benchmarks in the 2020s.

Another misconception is that meeting modern standards is synonymous with "zero risk." In technical terms, no building is entirely free of risk; rather, meeting modern standards indicates that the building aligns with the current "tolerable" level of risk as defined by the government and professional bodies. Finally, there is often confusion between "maintenance" and "meeting modern standards." While maintenance preserves the existing state, meeting modern standards typically involves an upgrade or alteration to bring the building into alignment with newer, more stringent codes.

Related Terminology#

To fully grasp the scope of meeting modern standards, it is helpful to understand several closely related industry terms:

• As-Built vs. As-Designed: The difference between the original plans and what was actually installed on the building.
• Material Change of Use: A regulatory trigger that often necessitates a building being brought up to modern standards.
• Competent Person: A professional with the necessary training and experience to certify that works meet modern requirements.
• Functional Requirement: The high-level goals of the Building Regulations (e.g., "the external walls shall adequately resist the spread of fire") that modern systems must satisfy.
• Legacy System: A cladding or insulation setup that was installed under previous versions of the regulations and may no longer meet modern criteria.

In summary, "meet modern" serves as a shorthand for the alignment of a building's external wall system with the contemporary legal and technical landscape of the UK construction industry. It is the baseline for all remediation and refurbishment activity aimed at ensuring long-term viability and safety.
