Everything you need to know about professional endorsement services in Singapore — PE, LEW, Licensed Plumber, Licensed Surveyor, and Gas Service Worker.
Singapore has five main categories of professional endorsement: PE (Professional Engineer) endorsement under PEB for structural and M&E works; LEW (Licensed Electrical Worker) endorsement under EMA for electrical installations; Licensed Plumber (LP) endorsement under PUB for plumbing works; Licensed Surveyor endorsement under SLA for land and strata surveys; and Gas Service Worker (GSW) endorsement under EMA for gas pipe installations and works.
The right endorsement depends on the type of work and the authority involved. Structural works → PE. Electrical works → LEW. Plumbing works → Licensed Plumber. Land/strata surveys → Licensed Surveyor. Gas pipe works → Gas Service Worker. Many projects need more than one type. WhatsApp Er. David at +65 9800 4385 to describe your project and get a clear, no-obligation recommendation on which endorsements apply.
Yes. Endorse.sg is designed specifically for projects that require multiple endorsement types. Rather than engaging separate professionals for PE, LEW, plumber, and gas works, you have one point of contact who coordinates all required endorsements. This reduces administrative burden, avoids miscommunication between trades, and is especially valuable for A&A projects, shophouse renovations, and new developments.
Indicative fees: PE endorsement from S$500; LEW endorsement from S$400; Licensed Plumber endorsement from S$450; Licensed Surveyor endorsement from S$800; Gas Service Worker endorsement from S$500. All fees depend on project scope, complexity, and documentation quality. Endorse.sg provides fixed-fee quotes within one working day — no hidden charges and no obligation.
Consequences vary by authority and trade. For structural works without PE endorsement: stop-work orders and fines up to S$200,000 under the Building Control Act, plus compulsory reinstatement. For electrical works without LEW: criminal liability under the Electricity Act. For gas works without a GSW: criminal liability under the Gas Act. For plumbing without LP endorsement: PUB will not commission the installation. Always obtain required endorsements before commencing regulated works.
PE endorsement in Singapore is the formal certification by a Professional Engineer registered with the Professional Engineers Board (PEB), confirming that proposed structural or M&E works are safe and comply with the Building Control Act. Only a PEB-registered PE can legally provide this endorsement. Endorse.sg uses Er. David Zheng (PE Civil, PEB No. 4385) for structural/civil works and Er. Lu Min Thet (PE Mech, PEB No. 4379) for mechanical and M&E works.
For load-bearing walls in HDB flats, PE endorsement is mandatory. For non-load-bearing walls, PE endorsement may still be required by HDB or your MCST depending on the scope of works. Endorse.sg can advise based on your unit's specific layout and HDB block type.
A QP (Qualified Person) is a PE or registered architect formally appointed under the Building Control Act to supervise building works and submit plans to BCA on behalf of the owner. A PE provides endorsement of the engineering design; a QP takes on the statutory duty for the whole submission and supervision process. QP.sg (our sister site) specialises in QP submission services — see qp.sg for details.
A Licensed Electrical Worker (LEW) is licensed by EMA under the Electricity Act to carry out and supervise electrical works in Singapore. Their endorsement (signing the Electrical Installation Record / EIR) is required before SP Services can activate a new electricity connection or before EMA can renew an electrical licence. No person may legally carry out electrical works without being a LEW or being supervised by one.
Most commercial and industrial electrical installations require annual inspection and licence renewal by an LEW. The LEW must inspect, test, and endorse the installation before renewal can be processed by EMA / SP Services. Residential premises have longer renewal periods. Endorse.sg can handle your periodic LEW inspection and endorsement on a fixed-fee basis.
If your renovation involves any alteration to water supply or waste pipes — including relocation of toilets, basins, or floor traps — a Licensed Plumber must supervise and endorse the works. Simple cosmetic tiling without pipework changes may not require LP endorsement, but any plumbing alteration generally does. HDB may also require the LP's sign-off as part of the renovation permit process.
A Licensed Surveyor is required when you need to subdivide land, form strata lots (condominium or mixed-use), register a change in boundaries with SLA, or obtain CSC/TOP requiring as-built survey certification. Most development projects require Licensed Surveyor involvement at multiple stages from planning approval through to title registration.
No. Gas pipe works must be carried out by or under the direct supervision of an EMA-licensed Gas Service Worker (GSW). A PUB Licensed Plumber licence does not authorise gas works — they are separate licences under different Acts (Gas Act vs Public Utilities Act). Engaging an unlicensed person for gas works is a criminal offence and creates serious safety risks.
