9 Best Plumbers in Singapore (2026)

Here is the part most people skip. In Singapore, certain water and sanitary works legally require a PUB-licensed plumber, known as a Licensed Plumber or LP. This is not marketing fluff. Works that connect to the public water supply, like installing or replacing a storage water heater, altering water supply pipes, or replacing water fittings, fall under PUB regulation, and an LP is the only person allowed to certify them. A general handyman doing this work is not just risky, it can be non-compliant.

For everyday jobs, the line is softer. Clearing a choke, fixing a leaking tap, swapping a toilet seat or unclogging a floor trap does not always need an LP. But here is my honest take: the good PUB-licensed firms handle both the regulated and the everyday work anyway, so hiring one for everything saves you from guessing where the line sits. A proper licence number (you will see formats like LP or WS followed by digits) is the single fastest credibility check you can do before letting someone into your flat.

The other thing I look for is a real 24-hour response and a transparent callout fee. A burst pipe or a backed-up toilet does not wait for office hours, and the firms worth trusting will tell you the inspection fee and the nett price before they touch anything. If a water heater job also involves the electrical connection, you may want a licensed electrician on the same visit (my best electricians in Singapore guide covers that), and if your "leak" is actually condensation dripping from a unit, it might be an aircon issue, which my best aircon servicing in Singapore guide handles.

Mr Plumber is the one I point most people to first, and it comes down to trust at scale. They sit at 4.9 stars across well over four thousand Google reviews, which is a volume almost nobody else in this trade comes close to. That many reviews makes the rating very hard to fake or fluke, and the consistency in them is what stands out.

They are PUB licensed (licence WS17962021) and BCA certified for plumbing and sanitary works, with 24-hour teams running every day of the week. So whether it is a 2am choke, a leaking pipe, a water heater swap or a toilet that will not stop running, they cover the full range for HDB, condo and commercial properties. They do not publish a fixed price list and prefer to quote over WhatsApp, which is the one thing to be aware of, but reviewers consistently describe the pricing as fair and explained upfront.

If you want the safest single default for almost any plumbing job in Singapore, this is it.

Nile Plumbing is my pick when you want transparent pricing without a phone call first. They are one of the few firms that actually publish starting prices on their site: inspection from S$60, clear choke from S$150, tap replacement from S$120, water heater installation from S$160. For anyone nervous about being quoted a number on the spot, seeing real figures upfront is a relief.

They are PUB licensed (WS18142021) and BCA certified, sit around 4.9 stars on Google, and run a genuine 24-hour service with an average arrival of 30 to 45 minutes for emergencies. The detail I like most is the 90-day leak-free warranty: if the same leak or choke comes back within three months, they return and fix it free. That is the kind of accountability that separates a real firm from a fly-by-night.

They cover HDB, condo and landed across most of the island, with strong presence in the central and northeast estates.

Best known for: Published nett pricing plus a 90-day leak-free warranty.

Wong Plumber has built a reputation around HDB work specifically, and the reviews reflect it: a perfect 5.0 rating from verified customers who repeatedly mention prompt arrival and fair, no-surprise pricing. When a firm holds a clean five-star record, I read every review carefully, and here the recurring themes are speed and honesty.

They are a PUB-licensed plumber (LP WS18752023) covering choke clearing for toilets, basins, sinks, floor traps and urinals, leaking tap repairs, toilet bowl and cistern work, and leaking pipe service across copper, stainless steel and UPVC. The service runs 24/7 islandwide, from Bedok and Tampines in the east to Jurong and Clementi in the west, with same-day appointments available.

If you live in an HDB flat and want someone who does this exact kind of work day in, day out, Wong is an easy recommendation.

Google Rating: 5.0 stars (verified reviews)
Best known for: HDB-focused PUB-licensed plumbing with prompt same-day response.

QB Plumbing earns a spot because it does the one thing nervous customers love: it puts package prices on the website. An instant heater package at S$458, a storage heater package at S$518, a toilet overlay package at S$988. You may still need a custom quote for unusual jobs, but seeing fixed numbers for the common ones removes a lot of the haggling anxiety.

They are a PUB-licensed plumber available 24 hours, seven days a week, covering water heater installs, toilet bowl repair and replacement, water pipe leak detection, drain cleaning, kitchen sink and tap replacement, ceiling and roof leak repair, plus bathroom waterproofing and HDB and industrial work. That spread makes them a good fit when your job is bigger than a single tap.

Good choice if you want a clear package price for a water heater or toilet job before anyone shows up.

Direct Plumber SG is the budget-friendly pick on my list, leading with "from $35" for general plumbing and positioning itself as one of the more affordable options in town. For small, straightforward jobs where you do not want to overpay, that low entry point is genuinely useful.

Operated by 777 Home Services, they bring 29 years of combined experience across pipe leak repair, toilet bowl repair and replacement, sink and kitchen choke clearing, floor trap and drainage work, tap and mixer installation, and water heater support. They serve the whole island, with named coverage across Tampines, Ang Mo Kio, Clementi, Marina Bay and beyond, and they carry a verified review badge for maintaining a score above 4.5.

Just confirm the licensing scope directly if your specific job is a regulated water-supply work, since the site leans more on price and coverage than on licence detail.

Google Rating: 4.5+ (verified review badge)
Best known for: Low entry pricing from S$35 for small everyday jobs.

As the name suggests, HDB Plumber Service is built around flat-dwellers, and they bring serious tenure: 25 years in the trade. When something is leaking in an older HDB block with quirky pipework, experience like that counts for a lot.

Their plumbers are PUB licensed and they run around-the-clock for emergencies, covering leak detection and pipe replacement, toilet and tap installation, water heater servicing, and drain and choke clearing across HDB, condo and commercial properties. Pricing is positioned low, with simple repairs like fixing leaks or replacing taps starting from around S$40 to S$50, and they provide an upfront quote before any work begins.

A sensible call for everyday HDB repairs where you want experience without a premium price tag.

Best known for: 25 years of HDB plumbing experience at low entry prices.

EZ Plumber is a solid 24/7 option, especially if you are out west. They are based in Jurong West, hold a 4.9 rating, and pitch themselves squarely on round-the-clock emergency cover across the island. For a late-night choke or leak in the western estates, proximity can mean a faster arrival.

The work covers pipe repair and leak detection, water heater installation, repair and maintenance, toilet and bathroom repairs, kitchen and sink solutions, and commercial plumbing. They quote per issue rather than publishing a price list, with free quotes through their enquiry system, so ask for the nett figure upfront before confirming.

Worth a call if you live in the west and need someone available at odd hours.

Location: Jurong West, serving islandwide
Google Rating: 4.9 stars
Best known for: 24/7 emergency response with a strong western Singapore base.

PW Plumbing is a steady, experienced general plumber with more than 10 years behind it and a base in Tampines. They are not the flashiest site on this list, but reviewers consistently flag reasonable, affordable rates even on emergency jobs, which is exactly what you want when you are caught off guard.

Their range is wide: plumbing fixture installation and repair, waterproofing, pipe repair and leak detection, rubbish chute installation and maintenance, water heater work, and toilet bowl choke repair, serving HDB, commercial, industrial and F&B premises like restaurants, hawkers and food courts. That F&B and commercial depth makes them a useful pick for small businesses, not just homes.

Their listed hours run long rather than strictly 24-hour, so confirm availability if your job is a deep-night emergency.

Best known for: Affordable general and commercial plumbing, including F&B premises.

ADM Plumbing rounds out the list with strong 24/7 emergency cover and a northern base in Woodlands Industrial Park. They describe themselves as on standby 24 hours a day, 365 days a year, which, for residents up north in Woodlands and Yishun, can mean one of the quicker responses available.

The service menu is detailed and practical: WC and urinal repairs, toilet choke clearing, leaking pipe repairs, water heater installation, drainage clearing, grease trap maintenance, kitchen and basin mixer replacement, shower and bidet mixer swaps, bottle trap installation, concealed flush system repairs and sensor tap servicing. They emphasise transparent, fixed pricing with upfront quotes and free WhatsApp estimates.

A good shout if you are in the north and want a 24-hour plumber with a clear, fixed-quote approach.

Prices vary by job complexity, parts and time of day (after-hours emergencies cost more), but here are the realistic ranges I see across the firms on this list. Treat these as a guide and always get the nett quote confirmed before work starts.

The single biggest cost driver is whether the issue is contained or hidden. A visible leaking tap is cheap and quick; a concealed pipe leak behind a wall or under a slab means detection work, hacking and reinstatement, which is where bills climb. After-midnight emergency callouts also carry a premium, so if it is not urgent, booking for daytime usually costs less.

1. A PUB licence where the job requires it. For water-supply and regulated sanitary works, a Licensed Plumber (LP) number is non-negotiable. For everyday jobs it is still a strong trust signal.
2. A transparent callout or inspection fee. The firm should tell you the inspection cost and the nett repair price before they start, not after.
3. Genuine 24-hour availability. Burst pipes and chokes do not keep office hours, so a real round-the-clock line matters for emergencies.
4. Reviews at volume, not just a high star count. A 4.9 across thousands of reviews tells me far more than a perfect score across a handful.
5. A workmanship warranty. A 30 to 90-day guarantee that the same fault will be re-fixed free shows the firm stands behind its work.

I am a web designer, not a plumber, so I will be upfront about my method. I searched the way a frustrated homeowner would (best plumber Singapore, 24 hour plumber Singapore, PUB licensed plumber), then visited each firm's actual website and checked the things that signal a real, accountable business: a visible licence number, clear pricing or at least a stated callout fee, genuine 24-hour cover, and the depth and consistency of their Google reviews.

Where I could verify a rating or review count, I have stated it; where I could not, I have described the reputation qualitatively rather than invent a number. I have not been paid to include anyone here, and every external link is a plain editorial reference. Ratings and prices shift over time, so confirm the current quote and licence directly with the plumber before you book. If you spot something out of date, that is on me to update.

For certain works, yes. Any job that connects to or alters the public water supply, like installing or replacing a storage water heater, changing water supply pipes, or replacing water fittings, must be done by a PUB-licensed plumber (LP) in an HDB flat or condo. For non-regulated everyday jobs such as clearing a choke, fixing a leaking tap or replacing a toilet seat, you have more flexibility, but most reputable firms are LP-licensed anyway, so hiring one keeps you compliant without having to figure out which side of the line your job falls on.

A standard callout or inspection fee usually sits between S$40 and S$80, and many firms waive or rebate it against the repair if you go ahead with the work. After-hours and emergency callouts (late night, public holidays) typically carry a premium on top. The key is to ask for the callout fee and whether it is absorbed into the job before the plumber comes out, so there are no surprises. Any firm that refuses to state its callout fee upfront is a red flag for me.

Yes, several firms on this list run genuine round-the-clock teams. Mr Plumber, Nile Plumbing, Wong Plumber, QB Plumbing, EZ Plumber and ADM Plumbing all advertise 24-hour or 24/7 emergency response, and some quote average arrival times of 30 to 45 minutes for urgent cases. For a true emergency like a burst pipe or an overflowing toilet, call the firm closest to your area first, since proximity often beats reputation when minutes matter. Just confirm that the after-hours rate is quoted before they dispatch.

The best defence is getting the nett price agreed before any work starts, in writing over WhatsApp if you can. Ask for a clear breakdown (callout, labour, parts) rather than a single lump sum, and do not authorise extra work mid-job without a fresh quote. For bigger jobs like water heaters or concealed leak repairs, a second quote from another firm on this list takes ten minutes and gives you a sanity check on the price. Firms that publish pricing, like Nile or QB, are inherently easier to hold to a number, which is part of why I rate that transparency so highly.
