Clearing a choked toilet bowl is the single most common plumbing job in Singapore, and the published price for it ranges from S$70 to S$150 across the eight companies below. That is more than double, for the same fault, in the same flat. We read every rate off each company's own website on 27 August 2026 rather than from any directory, and the gaps that matter are not in the headline numbers. Get Plumber lists the lowest rate at S$70, but the same page separately publishes a S$30 transport charge, a from-S$50 minimum plumbing fee and S$20 for each hardware-store run. FixMove advertises no call-out or inspection fee at all, then adds a S$10 fuel surcharge to every visit and S$30 if you want a specific time slot. AOT is the only firm here that publishes its after-hours surcharge as a table, and it is steep: plus S$50 on a weekday evening, plus S$80 to S$100 after 10pm, plus S$100 to S$150 on a public holiday. Only three of the eight publish a PUB licence number you can actually check on PUB's own register (AOT WS16882018, Mr Plumber WS17962021, Nile WS18142021). And two names that most roundups list as separate companies are not: Mr Plumber Singapore and Everyworks give the same WhatsApp number, 8241 0032, and the same address at 1090 Lower Delta Road, while Mr Plumber's own site carries an Everyworks network graphic listing both brands alongside DW Aircon, Daylight Electrician and A1 Handyman. Their price lists still differ, so which of the two you should message depends entirely on the job.
A choked toilet is the most-called-out plumbing job in Singapore, and the published price for it runs from S$70 to S$150 depending purely on whose number you have saved.
> Quick view: lowest published rate is Get Plumber, from S$70, though its own page adds S$30 transport and a from-S$50 minimum; most firms sit at S$80 to S$150, and only three of the eight publish a PUB licence number.
Why the same job costs double
Nothing above is a discount war. The spread from S$70 to S$150 on one toilet choke comes from three things, and all three are decided before anyone opens a toolbox.
The first is what the quoted rate is supposed to cover. Mr Plumber and Everyworks state their rates already include transport, labour and basic materials, which is why they read higher. Get Plumber's table says the same, but the same page also prices transport at S$30 separately. AOT quotes labour only and says so, with parts, hacking and reinstatement priced on top.
The second is the hour. AOT is the only firm here that publishes the surcharge grid, and it is worth reading even if you call someone else, because it is a fair map of the trade: roughly plus S$50 for a weekday evening, plus S$80 to S$100 overnight, plus S$100 to S$150 on a public holiday. Mr Plumber's after-hours call is S$150 to S$350. FixMove charges S$30 simply for a slot you choose. If the leak can wait until Monday morning, waiting is the biggest single saving available.
The third is scope, which is where headline numbers mislead most. Family Plumber's S$10 to S$60 is a basin cleared by hand; the same page prices a toilet at S$120 to S$400. Read the row, not the banner.
The licence question, and how to check it yourself
Regulated water service and sanitary plumbing work in Singapore has to be carried out by, or under, a PUB Licensed Plumber. That covers new pipe runs, work on the water supply, wall-embedded pipes and storage water heater installation, which is why Mr Plumber's storage-heater packages include a PUB submission and its instant-heater packages do not.
Three of the eight companies here publish a licence number on their own site: AOT (WS16882018), Mr Plumber Singapore (WS17962021) and Nile Plumbing (WS18142021). The other five describe their people as licensed without giving a number. That is not proof of anything either way, but it does mean you have to ask.
PUB runs a public register at eservices.pub.gov.sg called Find a Licensed Plumber, searchable by name or licence number and filterable by the type of sanitary or water service work you need. It sits behind a CAPTCHA, so it is a two-minute job rather than an instant one. PUB's own advice on that page is the best line in this guide: it is good practice to get three quotations before confirming your engagement with a Licensed Plumber.
How to choose, in four lines
Choose AOT if you want the fullest picture of the bill in advance, including the night surcharge. Choose Mr Plumber for anything tied to a renovation or a storage water heater, or for a genuine emergency at an antisocial hour. Choose Nile when the fix has to hold, and take the 90 days in writing. Choose Home Plumbers or Family Plumber when it is a plain choke and you want it cleared cheaply and fast.
Whoever you call, do the same three things: send a photo on WhatsApp and get a range before dispatch, ask whether the figure includes transport and GST, and ask for the licence number if the work touches a pipe in a wall.
