Due

Definition and Application in the Cladding Sector#

In the context of the UK built environment and external wall systems, the term "due" refers to an event, action, or document that is expected or required to happen at a certain time or in a specific manner. It denotes a point of necessity dictated by statutory cycles, contractual obligations, or the technical progression of remedial works. Within the cladding industry, the term transitions from a general temporal descriptor to a precise marker of regulatory compliance and asset management.

When an assessment or remedial action is described as "due," it indicates that a deadline—whether legal, safety-critical, or procedural—has been reached or is imminent. This applies to the lifecycle of a building’s facade, from the initial fire risk appraisal of external walls (FRAEW) to the periodic inspection of specific components such as cavity barriers, fire dampers, or integrated mechanical systems within the cladding buildup.

Role in Testing and Assessment Cycles#

The cladding industry relies heavily on cyclical evaluations to ensure that the building fabric continues to perform as intended. Under current UK frameworks, specifically regarding the Fire Safety Act 2021 and the Building Safety Act 2022, certain assessments become "due" based on the height, occupancy type, and existing safety record of a building. For example, a FRAEW conducted under PAS 9980:2022 may be deemed due if there has been a significant change to the building’s use, or if a previous assessment has expired according to the recommendations of a qualified professional.

In testing scenarios, the term relates to the scheduling of intrusive investigations. If a building's original "as-built" information is missing or deemed unreliable, an investigation into the composition of the external wall system becomes due. This involves the removal of small sections of cladding to identify the core material of panels and the presence or condition of insulation and fire stopping. The determination of when these actions are due is typically influenced by the building’s risk profile and the requirements of the Accountable Person or Principal Accountable Person.

Regulatory Context in England and Wales#

The regulatory landscape in England and Wales has formalised the concept of "due" actions through the introduction of the Gateways process for high-rise residential buildings (HRBs). During the design and construction phase, specific submissions to the Building Safety Regulator (BSR) are due at Gateway 2 (pre-construction) and Gateway 3 (completion). Failure to provide these when they are due results in a halt to the project, as the legal requirement to proceed is contingent upon these regulatory milestones.

For existing buildings, the "due" nature of safety documentation is often linked to the Golden Thread of information. Managing agents and owners must ensure that safety cases and digital records are updated whenever modifications occur. Furthermore, the mandatory registration of HRBs with the BSR established a hard deadline; buildings that were not registered by the due date were in breach of the new statutory requirements. The concept of "due" here is not a suggestion but a legal threshold that triggers enforcement possibilities if missed.

Implications for Building Fabric and External Wall Systems#

Regarding the physical building fabric, "due" often pertains to maintenance and the end-of-life cycles of specific cladding materials. Different systems—such as Aluminium Composite Material (ACM), High-Pressure Laminate (HPL), or render systems—have varying lifespans and maintenance requirements. A technical audit might conclude that a replacement or significant repair is due because the system has reached the end of its functional life or no longer meets current performance standards.

The table below outlines common triggers that render specific cladding-related actions "due":

Guidance for RMCs, RTMs, and Managing Agents#

For those responsible for building management, such as Directors of Resident Management Companies (RMCs) or Right to Manage (RTM) companies, understanding when actions are due is a core component of fiduciary and safety duties. A common area of focus is the "due diligence" process. This involves a systematic review of all cladding-related documentation to ensure that no statutory inspections have been overlooked and that the building’s safety case is robust.

Managing agents must distinguish between actions that are due as a matter of best practice and those that are due as a matter of law. While routine cleaning of a facade might be due according to a service charge schedule, the inspection of fire-spread risk is due according to the Regulatory Reform (Fire Safety) Order 2005. Miscalculating these timelines can lead to increased costs, insurance complications, or the inability for leaseholders to sell or remortgage their properties if EWS1 forms or alternative certifications are not provided when due.

Common Misunderstandings#

A frequent misconception is that a cladding inspection is only "due" if there is visible damage to the exterior of the building. In reality, many systemic issues, such as the absence of cavity barriers or the presence of combustible insulation, are not visible from the ground. Therefore, an assessment may be due based on the building’s age and original specification regardless of its aesthetic condition.

Another misunderstanding involves the EWS1 (External Wall System) form. There is often confusion regarding when a new form is due. An EWS1 form is generally valid for five years; however, it may become due for renewal sooner if significant changes are made to the wall system. Conversely, not every building requires an EWS1, and assuming one is due without professional consultation can lead to unnecessary expenditure.

Related Terminology#

• Statutory Deadline: A specific date by which a legal requirement must be met, often the ultimate point at which an action is due.
• Cycles of Inspection: The scheduled frequency (e.g., annual or quinquennial) at which building fabric reviews are expected to occur.
• Remediation Trigger: A specific finding or regulatory change that makes a repair or replacement project due for commencement.
• Compliance Schedule: A document detailing all upcoming dates when reports, tests, or maintenance tasks are due.
• Grace Period: A defined timeframe after an action becomes due during which it can be completed without immediate penalty, though this is rare in high-stakes safety contexts.

In summary, the term "due" serves as the temporal anchor for building safety and maintenance. Whether it refers to the submission of a safety case, the renewal of a fire risk assessment, or the commencement of cladding replacement, it signifies a transition from a planned state to a required action. Precise adherence to when these milestones are due is a fundamental aspect of professional property management and regulatory adherence in the UK cladding sector.
