Under Singapore’s Building Control (Amendment) Regulations 2026, lightning protection systems must be designed to protect buildings and their occupants, and lightning protection compliance now hinges on a Professional Engineer (electrical) preparing and certifying the LPS plans. Any project with a gross floor area of 30,000 m² or more must submit these plans now. The immediate action for a developer or design team is to engage a PE (electrical) early and commission a risk assessment under SS 555 before the concept design freezes.
TL;DR:
- Projects of 30,000 m² or more must submit lightning protection system plans certified by a registered electrical professional and retain testing records for ongoing compliance.
- The risk assessment under SS 555 Part 2 guides designing a cost-effective LPS tailored to each building’s exposure, avoiding unnecessary blanket coverage.
- LPS plans must include detailed site, roof, elevation, and floor layouts, with records of testing results available for inspection during the building’s operational life.
- Involving a PE (electrical) early ensures proper integration of the LPS with architectural and structural features, reducing costly rework later in the project.
- Engaging a specialized consultancy like Aman Engineering streamlines statutory approvals and supervision, helping projects stay on schedule as thresholds may change in future phases.

What Does Lightning Protection Compliance Require Under the 2026 Regulations?
The Building Control (Amendment) Regulations 2026 formally add lightning protection systems (LPS) to the list of required plan particulars submitted for approval. The regulations state a clear intent: an LPS must guard the building fabric against physical damage from a lightning strike and protect occupants from the electrical currents that a strike generates. New regulation 11A sets out exactly what must appear on submitted plans, closing a gap where LPS design once sat outside formal statutory review.
The amendment also introduces obligations that extend past design approval into the building’s operating life. Compliance with lightning regulations now means keeping evidence, not just drawings.
- LPS plans must be included among the particulars required for building plan approval.
- Regulation 11A specifies the drawings and details the Commissioner of Building Control expects to see.
- Owners and their engineers must retain inspection and test records, including electrical continuity and earth-termination resistance results.
- Records must be available for inspection, supporting ongoing lightning protection system inspection cycles rather than a one-time certification.
Which Standards Govern Lightning Protection Design in Singapore?
Singapore Standard SS 555 is the technical code of practice referenced when regulators assess whether a design meets its statutory duty. The series runs across four parts, each mapped to a corresponding part of IEC 62305 but adapted with local lightning intensity data and installation guidance.
- Part 1 covers general principles: how lightning damages structures and the rationale for protection.
- Part 2 sets out the risk-management procedure used to decide whether protection is needed at all, and to what level.
- Part 3 addresses physical damage to structures and life hazard, covering air-termination systems, down-conductors, and earthing.
- Part 4 deals with electrical and electronic systems inside structures, including surge protection.
Part 2’s risk assessment is the part practitioners lean on most, because it stops LPS design from becoming a default, one-size-fits-all exercise applied to every roof regardless of exposure.
Who Must Sign Off on Lightning Protection Systems?
Responsibility for LPS design and supervision sits with named, qualified individuals, not with a contractor’s in-house team acting alone. The regulations draw a firm line between who designs the system and who verifies it was built as designed.
- A Professional Engineer registered in electrical engineering must prepare and sign the LPS plans before submission. This is a statutory requirement, not a recommendation, and covers the electrical engineering scope of the project.
- A PE (Supervision, Electrical) oversees installation and issues the Certificate of Supervision once continuity and earth-resistance testing confirms the system performs as designed.
- The project team coordinates the LPS scope with architectural and structural submissions early, since air-termination layouts affect roof detailing and bonding points affect facade and M&E coordination.
Bringing the PE (electrical) in after the architectural concept is locked almost always forces rework on rooftop equipment layouts and parapet detailing.
When Do LPS Plans Need to Be Submitted?
BCA is rolling out LPS submission requirements in phases rather than applying them to every project simultaneously. Right now, submission is mandatory for developments with a gross floor area of 30,000 m² or more.
- Projects below the current GFA threshold are not yet required to submit LPS plans, but this requirement will be phased in for smaller developments over time.
- The Building and Construction Authority has committed to giving at least six months’ notice before extending the requirement to a new project category.
- Watch BCA circulars and CORenet announcements directly, since threshold changes will arrive there before they reach general guidance documents.
- Build a schedule contingency into procurement now. A project that sits just under the threshold today may not sit there by the time it reaches tender.
Treat the notice period as a planning window, not a grace period. Six months disappears quickly once structural and M&E tenders are already out.
What Must Appear on Your LPS Plans?
Regulation 11A is specific about the drawings and particulars that must accompany a submission, and reviewers will bounce a submission that omits any of them. Preparing CAD layers that map directly to these requirements speeds up the review cycle considerably.
- Site plan showing lot boundaries, lot numbers, a georeference, and distances to adjacent structures.
- Roof plan detailing the air-termination network and the layout of down-conductors.
- Elevation views showing the protection zones the LPS design achieves across the building envelope.
- Floor plans marking earth electrode locations and equipotential bonding details at points where services enter the building.
- Signed certificates and test or inspection records that the Commissioner of Building Control may request, including continuity and earth-termination resistance results.
Pro Tip: Set up your drawing template with these five deliverables as named layers from the start of schematic design. Retrofitting a submission to match regulation 11A after tender documents are issued costs far more time than building the structure into your CAD standard from day one.
How Do You Actually Achieve Compliance With Lightning Codes?
SS 555 Part 2’s risk assessment is the mechanism that turns a legal obligation into a specific, defensible design. Skipping straight to a blanket air-termination grid across every roof surface is common, but it is rarely the cheapest or most technically justified route.
- Run the risk assessment first. Building use, height, surrounding terrain, and local lightning flash density all feed into the calculation.
- Classify the LPS level the risk assessment indicates, rather than assuming the highest protection class by default.
- Develop the detailed design, air-termination, down-conductors, earthing, and bonding, once the classification is settled.
- Submit through the PE (electrical), with plans matching regulation 11A’s required particulars.
- Supervise installation and test, confirming electrical continuity and earth-termination resistance before commissioning.
- File the records and certificates, including the Certificate of Supervision, for the building’s operating life.
A tolerable-risk calculation under SS 555 Part 2 can justify a reduced or simplified external air-termination scope where the calculated risk already meets the acceptable threshold, which often changes the procurement cost for rooftop works materially.
How Aman Engineering Consultancy Supports LPS Compliance
Aman Engineering Consultancy’s electrical engineering and LEW team handles LPS design, PE endorsement, statutory submission, and supervision as a coordinated package rather than separate handoffs between consultants. That matters because rooftop LPS layouts interact directly with facade detailing, M&E routing, and structural penetrations for earth electrodes.
A practical engagement sequence starts with the PE (electrical) joining the design team at schematic stage, running the SS 555 risk assessment alongside the architectural concept, then carrying that design through statutory submission and on-site supervision toward the Certificate of Supervision and completed test records.
Perspective: What the 2026 Changes Mean for Project Timelines
The 30,000 m² threshold will not stay fixed. Teams below it today should still engage a PE (electrical) and book testing vendors during design, not after tender, because the six-month notice window for phase expansion will compress fast against a live construction schedule. Watching BCA circulars should be a standing task, not an afterthought.

Get Your LPS Compliance Scope Reviewed
Specialist consultancy firms provide a direct route to lightning protection compliance for developers who need a PE (electrical) to design, submit, and supervise an LPS without juggling separate consultants for each stage. This approach centers on single-point statutory coordination across a multidisciplinary PE team, which matters most on LPS work precisely because the rooftop, facade, and earthing scopes never sit in isolation from each other.
If your project sits near or above the 30,000 m² threshold, or you simply want the risk assessment done before committing to a rooftop layout, get in touch with Aman Engineering Consultancy for a scope review. The team can also fold LPS submissions into a broader authority approvals package if your project has other statutory clearances pending, so your PE (electrical) and PE (structural) submissions move on the same track instead of competing for review slots.

FAQ
What Are the Lightning Protection Requirements in Singapore?
The Building Control (Amendment) Regulations 2026 require LPS plans prepared and signed by a PE registered in electrical engineering, with design following SS 555. Submission is currently mandatory for projects with a gross floor area of 30,000 m² or more.
Does Every Building Need Lightning Protection?
Not automatically. SS 555 Part 2’s risk assessment determines whether protection is needed and to what extent, based on building height, use, location, and local lightning exposure rather than a blanket rule.
Does Lightning Protection Need to Be Certified?
Yes. A PE (Supervision, Electrical) must issue a Certificate of Supervision after testing confirms electrical continuity and earth-termination resistance meet the design. These test records must be retained and available for inspection.
What Are the Main Standards for Lightning Protection?
The SS 555 series, Parts 1 through 4, is Singapore’s authoritative code of practice for lightning protection design. It aligns with IEC 62305 while incorporating local lightning intensity data for Singapore’s tropical climate.
