Last updated 8 October 2026 — by Adrian Tan, SDM. Marketing guidance, not legal advice. Section numbers refer to the Electricity Act 2001, the Gas Act 2001 and the Public Utilities Act 2001 as currently shown on Singapore Statutes Online; check with EMA, PUB or a lawyer before relying on any point for a campaign.
Search “electrician Singapore” or “plumber near me” and you will find hundreds of ads: Google Ads with “24-hour licensed electrician” headlines, Facebook pages offering “same-day plumbing”, Carousell listings for water heater installation, and handyman directories that promise to “do everything”. Home services are a classic local-search category, and competition is fierce.
What many of these advertisers do not realise is that three Singapore statutes make the advertisement itself an offence if the advertiser is not properly licensed. The Electricity Act, the Gas Act and the Public Utilities Act each prohibit holding yourself out, by an advertisement or any other means, as authorised to do regulated work you are not licensed to do. For plumbing, the maximum penalty is a fine of up to S$10,000, up to three years’ jail, or both.
This guide explains what each statute says, what a handyman can legally advertise, what licensed businesses should put in their ads, and how marketing teams and agencies can avoid running campaigns that are offences in themselves.
The rules at a glance
| Trade | Advertising rule | Regulator | Maximum penalty |
|---|---|---|---|
| Electrical work | Electricity Act s 82(2) (individuals) and s 82(4) (businesses): no holding out “whether by an advertisement or any other means” as authorised, unless licensed | Energy Market Authority (EMA) | S$10,000 and/or 12 months, plus S$250 a day if it continues (s 92) |
| Gas service work | Gas Act s 11(1)(b): no advertising or holding out as a gas service worker, or as qualified to do gas service work, unless licensed or a practising professional engineer | EMA | S$10,000 and/or 12 months, plus S$250 a day (s 91) |
| Plumbing (sanitary and water service works) | Public Utilities Act s 40G(2) (individuals) and s 40G(4) (businesses): no holding out “whether by an advertisement or any other means” as authorised, unless a licensed plumber | PUB | S$10,000 and/or 3 years (s 40G(7)) |
| Any trade: false “licensed” or “approved” claims | Consumer Protection (Fair Trading) Act, Second Schedule item 2 | CCCS | Civil action, injunctions |
Electrical work: Electricity Act section 82
What the section says
Section 82 of the Electricity Act is built in layers. Section 82(1) stops an individual from carrying out, or offering or undertaking to carry out, electrical work unless they are a licensed electrical worker. Section 82(2) is the advertising limb: “An individual must not hold himself or herself out (whether by an advertisement or any other means) as authorised under this Act to carry out any electrical work, unless the individual is a licensed electrical worker.”
Sections 82(3) and 82(4) then apply the same logic to businesses. A person (which includes a company) must not hold out, by an advertisement or any other means, that it is authorised to provide electrical work in the course of business unless the work is done by licensed electrical workers or under their supervision. Section 82(5) makes it an offence for an owner or occupier to knowingly engage an unlicensed person.
Section 82(7) makes all of these offences. Because section 82 has no penalty of its own, the general penalty in section 92 applies: a fine of up to S$10,000, up to 12 months’ jail, or both, plus up to S$250 a day if the offence continues after conviction.
What a non-licensed handyman can still do
Section 82(8) carves out narrow exemptions. A person may replace a lamp or a household-type fuse in their own installation, and trades working on appliances may work on parts that are not connected to the supply. Those exemptions are about the work, not about marketing. They do not let a handyman advertise “electrical works”, “wiring”, “DB box upgrade” or “power point installation”.
There is no “EMA-licensed contractor”
A common phrase in electrical ads is “EMA-licensed electrical contractor”. The current Electricity Act licenses electrical workers, not contractors. Section 82(10) refers to the old Electrical Workers and Contractors Licensing Act only to keep old worker licences valid. A business can accurately say its work is carried out by EMA-licensed electrical workers. Calling the business itself an EMA-licensed contractor describes a licence that does not exist, which is a misleading claim under consumer protection law.
The three licence classes
Regulation 5 of the Electrical Workers Regulations sets three classes of licence: electrician, electrical technician and electrical engineer. An electrician may work on installations up to 1,000V and 45 kVA, and an electrical technician up to 500 kVA. A firm that advertises commercial or industrial electrical works beyond those limits needs workers holding the appropriate class, and its ads should not suggest a capability its licensed workers cannot legally deliver.
Regulation 16 requires EMA to keep a register of electrical workers, recording their names, licence numbers, issue and expiry dates and any convictions, and regulation 15 lets an EMA officer require a worker to produce their licence. Nothing in the Act or regulations requires a licence number to appear in an ad, but because the register exists, a stated licence number is a claim customers and competitors can check.
Gas service work: Gas Act section 11
The Gas Act is older and its wording is broader. Section 11(1)(b) says no person may “advertise or otherwise hold himself or herself out, or conduct himself or herself, in any way or by any means as a gas service worker or as a person who carries out or who is qualified by any written law to carry out gas service work” unless they are a professional engineer with a practising certificate or hold a valid gas service worker licence for that class of work.
Two parts of that wording matter for marketers. First, it names advertising directly. Second, it catches claims of being “qualified” to do gas work, not just claims of being licensed. An ad for “gas stove and gas water heater installation” from a business with no licensed gas service worker is squarely within it. Section 13 adds a separate offence of employing or instructing an unlicensed gas service worker, so a business cannot fix the problem by advertising the job and subcontracting it to someone unlicensed.
The general penalty in section 91 applies: up to S$10,000 and/or 12 months, plus up to S$250 a day if the offence continues. EMA keeps a register of gas service workers under regulation 26 of the Gas (Supply) Regulations.
Plumbing: Public Utilities Act section 40G
The offence
Section 40G of the Public Utilities Act mirrors the Electricity Act. Section 40G(2) says an individual must not hold himself or herself out, whether by an advertisement or any other means, as authorised to carry out regulated works unless a licensed plumber, and section 40G(4) applies the same rule to businesses. “Regulated works” means sanitary works, certain water service installation design works, and water service installation works.
The penalty is the heaviest of the three regimes. Under section 40G(7), breaching sections 40G(1) to (4) carries a fine of up to S$10,000, up to three years’ jail, or both. Owners and occupiers who engage someone other than a permitted person also commit an offence; PUB says it has been an offence to engage an unlicensed plumber since 1 April 2018.
What a handyman can advertise
PUB’s guidance draws the line in practical terms. Handymen may do simple jobs such as “replacing or removing any tap or mixer”. Regulated works, such as installing or altering water pipes, sanitary fittings and water heaters connected to the water supply, need a licensed plumber.
That gives a clear marketing boundary:
- Safe for an unlicensed handyman: “tap and mixer replacement”, “toilet seat replacement”, “showerhead replacement”, if those jobs are genuinely within PUB’s handyman category.
- Needs a licensed plumber: “plumbing works”, “pipe replacement”, “water heater installation”, “concealed piping”, “toilet bowl installation”.
- Never without a licence: “licensed plumber”, “PUB-approved”, “PUB-certified”.
PUB tells consumers to check its online search for licensed plumbers and to ask for at least three itemised quotes. Assume your customers, and your competitors, will check.
A note on aircon servicing
Aircon servicing is often advertised alongside electrical and plumbing work. NEA’s guidance indicates there is no general licence for servicing household air-conditioners: the duty to ensure service staff have completed ITE training for R32 systems falls on manufacturers, and the ITE certificate is voluntary for technicians. Chiller work has required certified technicians and NEA registration since 1 October 2022, and refrigerant from decommissioned equipment must be collected and properly treated.
The catch is installation. Running new power points or wiring for an aircon is electrical work, so an aircon company that advertises “installation including electrical works” needs licensed electrical workers to do that part. Advertise the electrical part only if a licensed worker will carry it out.
Consumer protection: false “licensed” claims
The three statutes deal with the unlicensed advertiser. The Consumer Protection (Fair Trading) Act deals with misleading claims more broadly, including claims by licensed businesses that go further than their licence. Several items in its Second Schedule list of unfair practices are directly relevant to home services:
- Item 2: representing that the supplier has a sponsorship, approval or affiliation it does not have. A false “EMA-licensed” or “PUB-approved” claim fits here.
- Item 3: misleading claims about the need for goods or services.
- Item 8: claims that repairs or replacements are needed when they are not.
- Item 9: representing price benefits that do not exist.
- Item 10: charging well above an estimate without the customer’s agreement.
The closest reported analogy is a 2021 State Courts declaration against a fire-safety trader that falsely claimed affiliation with SCDF or the government and quoted false prices. “Government-approved” language is exactly the kind of claim that attracts that response. Our guide to the Trade Descriptions Act for marketers covers the overlapping rules on false descriptions.
What licensed businesses should say in their ads
| Risky wording | Why | Better wording (if true) |
|---|---|---|
| “EMA-licensed electrical contractor” | The Act licenses workers, not contractors | “All electrical work done by EMA-licensed electrical workers” |
| “Licensed electrician” on a firm with one licensed worker and many helpers | Section 82(4) allows the business claim only if work is done by or under licensed workers | “Electrical work carried out or supervised by our EMA-licensed electrician” |
| “PUB-approved plumber” | A licence is not an endorsement | “PUB-licensed plumber, licence no. [number]” |
| “Gas cooker installation” (from a general handyman) | Gas Act s 11(1)(b) catches the ad | Offer it only with a licensed gas service worker |
| “Cheapest electrician in Singapore” | Unsupported superlative; item 9 risk | “Transparent quotes, itemised before we start” |
| “Your DB box must be replaced” | Item 8 risk if not genuinely needed | “Free inspection; we explain what needs fixing and why” |
Licence numbers
No rule requires licence numbers in ads, but showing them is one of the best trust signals in this category. It is verifiable, competitors without licences cannot copy it truthfully, and it answers the question PUB and EMA tell customers to ask. If you show a number, keep it current: when the worker leaves or the licence lapses, the claim becomes false.
Worked example: rewriting a handyman campaign
Consider a fictional home-services business with one EMA-licensed electrician on staff, no licensed plumber and no gas service worker. Its draft Google Ads campaign includes:
“Licensed Electrician & Plumber 24/7 | Gas Stove Installation | Water Heater Replacement From S$80 | EMA & PUB Approved”
Here is how we would rework it:
- Split the services by licence. Keep electrical works, because a licensed electrician does or supervises them. Remove plumbing, water heater installation and gas stove installation from the ads, or partner with a licensed plumber and gas service worker who actually carries out and is named for that work.
- Fix the credential claim. Replace “EMA & PUB Approved” with “Electrical work by EMA-licensed electrician”. Neither authority approves businesses in the way that phrase suggests.
- Check the price. “From S$80” must be a price at which the job is genuinely done, not a call-out fee that becomes S$300 once the technician arrives. State what the starting price covers.
- Clean up the keywords. Pause bidding on “plumber” and “gas” terms. Bidding on “licensed plumber” while sending clicks to a page that offers plumbing is holding out by advertisement.
- Audit every surface. The Google Business Profile categories, Facebook page, Carousell listings, van livery and directory profiles all count as “an advertisement or any other means”.
The result is a narrower campaign, but every click it buys can be converted legally. If the business later hires a licensed plumber, the plumbing services can be added back with that licence behind them.
Channel notes
- Google Search and Local Services. Keywords are part of the advertisement. Bidding on “licensed plumber” or “EMA electrician” while unlicensed sends a holding-out message before anyone reads the ad. Google Business Profile categories such as “Plumber” or “Electrician” make the same claim. Our guide to local SEO in Singapore covers profile set-up.
- Facebook, Instagram and TikTok. Short “before and after” videos of DB box or pipe work are effective, but a video showing regulated work by someone who is not licensed is evidence of the offence.
- Marketplaces and directories. Carousell services, handyman apps and directory listings are advertisements. Platform categories often bundle “electrical and plumbing”; list only what you are licensed for.
- Van livery and flyers. “Licensed electrician” painted on a van is holding out “by any other means”. It must stay true for as long as the van is on the road.
Related trades face similar rules. Renovation firms are covered in our guide to renovation contractor advertising, professional titles in our guide to architect, engineer and accountant advertising, and pest control in our guide to pest control advertising rules. Electrical firms installing home chargers should also read our guide to EV charger advertising rules, because only licensed electrical workers may install a fixed charger.
How the rules are enforced
Both regulators reported enforcement figures to Parliament in September 2026:
- Electrical: EMA received 20 reports of unlicensed electrical work between July 2025 and June 2026. Six investigations had been completed, with action taken in four. EMA has 11 inspectors.
- Plumbing: PUB detected 47 cases of unlicensed plumbing works in the past year and took 46 enforcement actions.
I found no published prosecution specifically for the advertising limb of any of the three statutes. That is not a safe harbour. An ad is often the evidence that starts an investigation into the work itself, and the advertising offence can be charged alongside the work offence. A complaint from a customer or a licensed competitor is all it takes.
Conclusion
Home services are one of the most competitive local advertising categories in Singapore, and also one of the few where the ad itself can be a crime. The rule is simple across all three trades: advertise only the work your licensed people can do, describe the licence accurately, and do not borrow EMA’s or PUB’s authority with “approved” language. Businesses that get this right turn licensing into a selling point, because a verifiable licence number is something unlicensed competitors cannot match.

Frequently asked questions
Is it illegal to advertise electrical work in Singapore without a licence?
Yes. Section 82 of the Electricity Act prohibits individuals and businesses from holding themselves out, by an advertisement or any other means, as authorised to carry out electrical work unless the work is done by or under licensed electrical workers. The maximum penalty is S$10,000 and/or 12 months.
Can a handyman advertise plumbing services?
Only the simple jobs PUB allows handymen to do, such as replacing a tap or mixer. Advertising regulated plumbing works, or holding out as a licensed plumber, without a PUB licence is an offence under section 40G of the Public Utilities Act, with up to S$10,000 and/or three years’ jail.
Is there such a thing as an EMA-licensed electrical contractor?
No. The Electricity Act licenses electrical workers, in three classes: electrician, electrical technician and electrical engineer. A business can say its work is done by EMA-licensed electrical workers, but should not describe itself as a licensed contractor.
Who can advertise gas stove or gas heater installation?
Only a licensed gas service worker or a professional engineer with a practising certificate. Section 11(1)(b) of the Gas Act makes it an offence to advertise or hold out as a gas service worker, or as qualified to do gas service work, without one of those.
Do I have to show my licence number in ads?
No rule requires it, but it is a strong trust signal because EMA and PUB keep registers that customers can check. If you show a number, keep it current and remove it if the worker leaves or the licence lapses.
Do aircon servicing companies need a licence to advertise?
NEA’s guidance indicates there is no general licence for servicing household aircons, though chiller work needs certified technicians. Any electrical work that is part of an installation, such as new power points, must be done by licensed electrical workers, so only advertise it if they will do it.
