Cladding Fire Compliance in Singapore: Fire Code 2023 Rules

Cladding fire compliance in Singapore is governed by the SCDF Fire Code 2023. Its external wall provisions in Clause 3.5, its material provisions in Clause 3.15 and its rules on regulated fire safety products in Chapter 11 set the requirements. Together they fix which materials may be used on a facade, which tests a composite panel must pass, what documents must accompany the product and who must report a suspected failure. This guide sets out those requirements in the order a project team meets them, from design to inspection to remediation.

TL;DR

External-wall cladding is regulated under Fire Code 2023 Clause 3.5 (external walls) and Clause 3.15 (materials), with composite panels subject to specific test and certification requirements.
Buildings taller than 15 m, or within 1 m of a relevant boundary, must have external walls of non-combustible construction, except for finishes that meet Clause 3.5.4.
QPs and Registered Inspectors who suspect non-compliant cladding must notify SCDF immediately. A known failed test left unreported has led to enforcement action.
Documentation matters: Certificates of Conformity, permanent product marking and site surveillance testing are part of the compliance trail.

The legal framework for facade cladding

The starting point is the Fire Code 2023 Clause 3.5 on external walls, which sets requirements for combustibility and fire resistance of external walls, including Clause 3.5.4 on external wall finishes. Clause 3.15 on materials for construction supplements it with the rules for composite panels.

The Fire Code defines external wall finishes broadly. According to the Code of Practice for Fire Precautions in Buildings 2023, the term covers materials or components on a building facade used for thermal insulation, weather resistance or appearance, and it explicitly includes cladding, fins and decorative features. A design team therefore cannot treat a decorative fin or an architectural screen as outside the scope simply because it is not a weather barrier.

A separate layer applies to the products themselves. The Fire Safety (Regulated Fire Safety Products) Regulations 2020 list a composite panel used as cladding to an external wall among the regulated fire safety products. This means the panel must be certified under the product certification scheme before it is supplied for use, in addition to meeting the Fire Code.

Which buildings and which cladding are caught

The height and boundary tests in Clause 3.5 determine how much freedom the designer has. Under the Clause 3.5 provisions, external walls of buildings exceeding 15 m in height, or situated within 1 m of a relevant boundary, must be built wholly of non-combustible materials and must attain the required fire resistance. The exceptions are external wall finishes complying with Clause 3.5.4 and internal linings complying with Clause 3.13.4.

In practice the assessment runs through three questions:

Height and boundary. Does the building exceed 15 m, or does any wall sit within 1 m of a relevant boundary?
Wall construction. If so, is the wall itself non-combustible and does it reach the required fire resistance rating?
Finish. Does the cladding, fin or decorative feature qualify under Clause 3.5.4, and if it is a composite panel, under the Clause 3.15 conditions?

The same logic applies to retrofits. A recladding project that changes the finish of an existing facade is a new decision on materials and needs the same checks, not a cosmetic change that sits outside the Fire Code.

Composite panels: tests, ratings and mounting conditions

Composite panels, typically aluminium skins bonded to a core, attract the most scrutiny because panels that look identical can perform very differently in a fire. Under Clause 3.15, composite panels used as external-wall cladding must be mounted against a 1-hour fire-rated wall and meet one of the following:

Route	Requirement
British Standard route	BS 476 Part 4 and Part 11, plus Class 0 under BS 476 Parts 6 and 7
European route	Class B under EN 13501-1
Assembly route	The panel assembly complies with NFPA 285

Two points deserve emphasis. First, the requirement is about the panel mounted against a rated wall, so the substrate is part of the compliance case and not an afterthought. Second, the assembly route evaluates the system as installed, which means that a change of insulation, cavity detail or fixing can alter the result.

Certification, marking and surveillance testing

Chapter 11 of the Fire Code adds product-level controls. Under Clause 11.8, Certificate of Conformity (CoC) holders must ensure that the brand, model, CoC reference, fire performance and manufacture date are printed legibly and permanently on composite panels used as cladding or roofing, and on their protective film.

The same clause requires surveillance testing of composite panels (honeycomb panels excluded) using samples from project sites, as set out in Table 11A. Where no site-specific samples are collected during the surveillance window, annual testing is required.

The background to these rules is documented in SCDF’s circular on external wall finishes of 21 January 2019. SCDF proposed project-site surveillance testing and permanent product information to reduce the risk of visually identical panels with different fire ratings being mixed up. A site team that photographs the marking on delivered panels and files it with the CoC has a practical record that matches the intent of the rule.

Who is responsible

Responsibility for cladding compliance is shared, and the Fire Code and SCDF guidance name the roles.

Party	Duty
Qualified Person (QP)	Checks that composite panels used as cladding comply, submits CoCs and supervises site testing
Registered Inspector (RI)	Verifies that requirements are fulfilled through inspection
Building owner	Must comply once informed and may be subject to orders if works or conditions are non-compliant
CoC holder (supplier)	Ensures permanent marking and certification of the panels

The allocation of QP and RI duties comes from the SCDF circular. Under the Fire Safety Act, an RI must notify SCDF of contraventions found where the owner fails or refuses to comply, and an RI inspection certificate is a prerequisite for a Temporary Fire Permit or Fire Safety Certificate. Cladding that has not been verified can therefore stall occupation of a new building. For the certificate side of this process, see our explainer on FC versus FSC certification.

The RI route also has a pragmatic element. The SCDF page on the Registered Inspector scheme describes Form 2 certificates, which allow temporary occupancy under strict conditions when minor non-compliances do not compromise core life safety. This is not a route for cladding that fails its fire performance requirements, where the matter goes to SCDF.

A documentation trail that stands up to audit

Project teams that handle cladding well assemble the evidence as the work proceeds, not at TOP stage. A workable file contains:

The facade design intent, with the height and boundary assessment under Clause 3.5.
The fire resistance rating of the backing wall and the basis for it.
The product’s CoC, the test route relied on (BS 476, EN 13501-1 or NFPA 285) and the full system detail where the assembly route is used.
Delivery records showing the permanent marking on panels and film, matched to the CoC reference.
Records of site surveillance sampling and results, where applicable.
QP supervision records and the RI’s inspection certificate.

Our guide to obtaining fire safety approval shows where this file fits in the wider SCDF submission sequence, and the role of SCDF in construction outlines the stages at which the authority checks it.

Existing buildings: assessing cladding already on the facade

Owners of older buildings often cannot say with confidence what their facade panels are. An assessment normally proceeds in this order:

Records review. Locate the original plans, the material specifications and any CoC or test reports from the time of construction.
Physical identification. Inspect the panels and look for manufacturer marking, then confirm the panel type, core and backing wall.
Testing where records are missing. A QP can arrange sampling and testing against the Clause 3.15 standards.
Fire safety assessment. Consider the proximity of the cladding to ignition sources, the proportion of wall covered and the available fire protection systems.
Remediation plan. Agree the scope with SCDF if a non-compliance is confirmed.

Step 4 mirrors the method SCDF itself applied in a real case, described below. Where the facade is also due for statutory checks, cladding condition can be reviewed alongside a periodic facade inspection, which keeps the owner’s inspection programme efficient.

Reporting duties and what happens when they are missed

The duty to report is explicit. Under the SCDF circular, a QP or RI who suspects that non-compliant cladding has been installed must notify SCDF immediately. The circular also states that installing non-compliant products without lawful excuse is an offence, and that SCDF proposed powers to order remedial action, including recall, stopping sale or removal from buildings.

The ICON@International Business Park case shows how this works. In SCDF’s 2019 news release, the owner had run its own burn test in March 2018 and the panels failed. The QP knew of the result in April 2018 but did not inform SCDF, and the owner alerted SCDF only in July 2019. SCDF found the building fit for occupancy based on its existing fire protection provisions, yet directed the owner to remove the cladding within 60 days. The delay between the failed test and the report was described as unacceptable.

The wider enforcement powers sit in the Fire Safety Act:

The Commissioner may order unauthorised fire-safety works to cease, be altered to comply or be demolished. If the order is ignored, the Commissioner may remove or alter the works or the building.
A person who carries out fire-safety works without approved plans can face a fine of up to $50,000, imprisonment of up to 12 months, or both, plus a daily fine of up to $1,000 for a continuing offence after conviction.

The lesson for owners and QPs is consistent: an adverse test result is a problem that can be managed with SCDF, while concealment or delay turns it into a professional and legal one.

Planning facade work for first-time approval

Most cladding problems are cheaper to prevent at design stage. Some habits reduce risk:

Fix the cladding system early. Late substitutions for cost or lead-time reasons are a common source of mismatch between approved plans and what is delivered.
Treat the backing wall as part of the specification. A compliant panel on a wall that does not achieve one hour does not meet Clause 3.15.
Specify marking and CoC checks at delivery as a contract requirement, so that rejection of unmarked panels is not a dispute later.
Keep fire compartmentation in view. Facade details can bridge compartments if cavities are not fire-stopped; our note on SCDF compartmentation limits covers the related rules.
Align the facade inspection cycle with the BCA periodic inspection schedule so condition data is gathered once.

Perspective: where cladding projects go wrong

From our work on authority submissions and facade-related engineering in Singapore, we see the same pattern. Cladding is rarely rejected because the Fire Code is unclear. It is rejected, or delayed, because the paper trail does not match the product on the wall: a CoC for one model, a delivery of another, a backing wall rated on assumption.

We advise project teams to treat cladding like a structural element: a named responsible person, a documented basis and verification at each hand-over. We also advise owners of existing buildings not to wait for a trigger. A records review and, where needed, sampling is far less costly than a removal directive, and it puts the owner in a position to report on its own terms.

How we support cladding compliance

We provide facade design services and manage statutory submissions to SCDF, BCA, URA and other Singapore authorities, together with PE endorsements and BCA periodic structural and facade inspections. Teams that need a second opinion on a cladding specification, or an owner who needs to establish what is on an existing facade, can start from our services overview and describe the project. We do not publish fixed prices, as scope depends on the building and the evidence already available.

FAQ

Does the Fire Code restrict cladding on every building?

The non-combustibility requirement for external walls applies to buildings exceeding 15 m in height or within 1 m of a relevant boundary. Finishes that comply with Clause 3.5.4 are the exception. Lower buildings still need to satisfy the other Fire Code provisions and the regulated product rules for composite panels.

Which standards can a composite panel meet?

Under Clause 3.15, a composite panel mounted against a 1-hour fire-rated wall must meet BS 476 Part 4, Part 11 and Class 0 under Parts 6 and 7, or Class B under EN 13501-1. Alternatively, the panel assembly must comply with NFPA 285. The QP confirms which route applies to the project.

What should a QP do if a panel fails a test?

A QP or RI who suspects non-compliant cladding has been installed must notify SCDF immediately. The owner should be informed at once, and the remediation approach is then agreed with SCDF. The 2019 ICON@IBP case shows that delay in reporting is treated as a serious failing.

Can panels be identified once installed?

Compliant composite panels carry permanent marking showing brand, model, CoC reference, fire performance and manufacture date, on the panel and its protective film. Where marking is not visible or records are missing, a QP can arrange sampling and testing to establish the panel type.
