Plumbing Services in Singapore: The Complete 2026 Guide
Simple tap, trap and visible leak jobs may be straightforward, but water service, sanitary plumbing and concealed pipe work can require a PUB Licensed Plumber. Send photos, symptoms and address first so the right scope is routed.
A choking toilet, a stain spreading across the ceiling, a water bill that suddenly doubled — most Singapore plumbing problems fall into just six job families, and knowing which one you have is what stops a quote from being inflated. Most common repairs cost S$60–$280 — a toilet choke starts from S$80 and a concealed pipe leak runs S$250–$600. Only "water service work" on the potable supply legally requires a PUB-licensed plumber; everyday repairs like tap washers and choke clearing do not. This guide breaks down each job, the 2026 price bands, and how to vet a plumber before anyone touches your pipes.

What do plumbing services in Singapore cover?
Almost every residential call-out falls into one of six families. Knowing which one you have makes quotes faster and harder to inflate:
- Chokes and blockages — toilet bowl, kitchen sink, basin, floor trap or the shared discharge stack. Recurring chokes usually mean the blockage is deeper than the fixture. See toilet choke service for the full breakdown of clearing methods.
- Leak repair — visible leaks at joints, traps and flexible hoses, and concealed leaks inside walls or floor slabs that show up as stains, damp cabinets or a rising water bill. Diagnosis paths are covered under water leak repair.
- Taps and mixers — washer and cartridge replacement, or swapping the whole tap body when it has corroded. A dripping tap is the cheapest fix on this list; see leaking tap repair.
- Toilet repairs — flush valves, fill valves, cistern reseals and full bowl replacement.
- Water heaters — instant (multipoint or single-point) and storage heater installation or replacement. Pricing depends on heater type; details at water heater installation cost.
- Pipe work — repairing or replacing exposed pipes, re-piping concealed runs after a slab or wall leak, and relocating supply points during renovation. For recurring leaks across several areas or ageing pipework, compare a whole-house repiping scope.
All six families, plus booking and warranty terms, are gathered on the main plumbing services Singapore hub.

What FixMove does
FixMove (registered ALL-IN-ONE FIX & MOVE, UEN 53505530K) comes to you anywhere in Singapore — your HDB flat, condo, office or shop. There is no counter to visit. One number covers eight kinds of work: aircon, plumbing, electrical, handyman, installation, moving, renovation and full-house customisation. We are open 24 hours, Monday to Sunday, and where the work is regulated we arrange the appropriately licensed person.
Visit charges: A S$10 fuel surcharge applies to every visit. No additional standard call-out or inspection fee applies. Urgent service or a customer-requested appointment time adds one S$30 fee, subject to technician availability and confirmation. The S$30 is a separate service fee. Repair, diagnostic labour and materials are quoted separately; work starts only after customer approval.

The full, regularly updated list lives on the plumber cost Singapore price page. The three variables that move a quote most are scope (how many fixtures or rooms), material tier, and site condition (accessibility and hidden damage).
When is a PUB-licensed plumber legally required?
PUB, Singapore's National Water Agency, requires a PUB Licensed Plumber for regulated water-service and sanitary plumbing works. Water-service work must comply with SS 636 (Code of Practice for Water Services); sanitary plumbing work must meet the applicable sanitary plumbing and sewerage requirements. PUB separately lists simple plumbing works — such as replacing a tap or P-trap and clearing a toilet or floor-trap choke — that a handyman may carry out. Confirm the actual scope before booking.
| Needs a PUB-licensed plumber | Does not need one |
|---|---|
| Extending or relocating water supply pipes (e.g. moving a sink during renovation) | Replacing tap washers, cartridges or a like-for-like tap |
| Installing or replacing a water heater connected to the supply pipework | Clearing a toilet, sink or floor trap choke |
| Re-piping after a concealed pipe leak | Replacing a flexible hose, bidet spray or shower head |
| Works on sanitary discharge stacks and drainage pipes | Resealing a cistern or replacing a flush/fill valve |
| Any work connecting to or modifying the water service installation | Sealing minor joint leaks on exposed fittings |
One related rule: if a storage heater needs a new heater point, the electrical side is regulated separately — new wiring must be done by an EMA-licensed electrical worker. A responsible company tells you up front which category your job falls into; FixMove states it in the WhatsApp quote before booking.
Emergency vs scheduled plumbing: what changes?
An emergency is anything with uncontrolled water: a burst pipe, a leak you cannot isolate, or a toilet overflowing onto the floor. Everything else — a dripping tap, a slow drain, a heater replacement — is cheaper and better done as a scheduled job.
If water is actively flowing, do this before calling anyone:
- Close the nearest isolation valve (under the basin or beside the cistern), or the main stopcock — in most HDB flats it is inside the service duct near the entrance.
- Switch off the water heater if the leak involves hot water pipes.
- Send a short video on WhatsApp so the plumber arrives with the right parts.
Emergency call-outs start from S$80 and are triaged on WhatsApp first — see emergency plumber Singapore for response times and after-hours coverage. Scheduled jobs get the standard rates above; weekday morning requests usually get a same-day afternoon slot.
How do you vet a plumber in Singapore?
Five checks separate a reliable plumber from a "cheap call-out, expensive surprise" operator:
- PUB licence check — for any water service work, ask for the plumber's name and licence number and verify it against PUB's public register of licensed plumbers on the PUB website.
- Written quote before work starts — a WhatsApp message counts. The quote should name the job, the price band, and what is excluded (e.g. tiling after a concealed-pipe repair).
- Itemised pricing — labour and parts listed separately, so you can see exactly what you are paying for. "Lump sum, decide on site" is where inflated bills hide.
- Registered business — check the company's UEN on ACRA's BizFile. Flyer operators with no traceable entity leave you nowhere to go if a repair fails.
- Workmanship warranty in writing — 30 days on the repaired part is the reasonable market standard. No warranty usually means no return visit.
HDB vs condo: what is different about the plumbing?
HDB flats
HDB plumbing is built around shared vertical stacks and a per-flat service duct, with three practical consequences. Recurring chokes can originate in the shared stack rather than your own fixture, so a snake through the floor trap often matters more than another bowl-level clear. Ceiling leaks are usually inter-floor seepage from the unit above — HDB treats this as a shared responsibility, and under its Goodwill Repair Assistance scheme repair costs are typically split between the upper and lower flat owners. Renovation-scope work such as relocating a sink or adding a heater point must follow HDB renovation guidelines and use appropriately licensed tradespeople.
Condominiums
In a condo, pipes inside your unit are your responsibility, while risers and common pipework belong to the MCST. Anything touching common property — including some concealed pipe runs — needs management approval first, and most managements restrict noisy work such as hacking to weekday working hours. Many condos also run pressurised systems from roof tanks or pumps, so a leak can discharge faster than in an HDB flat — know where your unit's isolation valve is.
How do you prevent plumbing problems in the first place?
- Never pour cooking oil or grease down the kitchen sink — it solidifies in the pipe and is the most common cause of kitchen chokes.
- Flush only the three Ps — pee, poo and (toilet) paper. Wet wipes, even "flushable" ones, are a leading cause of toilet and stack chokes.
- Lift and rinse floor trap covers monthly; hair and sediment build-up is the cheapest problem to prevent.
- Replace braided flexible hoses (under basins, behind cisterns) every 5–7 years — they fail suddenly and flood fast.
- Watch your water bill — an unexplained jump is the classic sign of a concealed leak. Confirm by closing all taps and checking whether the meter still moves.
- Service storage water heaters periodically and replace units showing rust streaks or weeping relief valves before they fail.
- Fix small drips early. A dripping tap is a S$60–$120 labour job today; the corrosion, swollen cabinet and concealed seepage it causes later are not.

FAQ
Do I need a PUB-licensed plumber for every repair?

What counts as a plumbing emergency?
Anything with uncontrolled water flow: a burst pipe, a leak you cannot isolate, or an overflowing toilet. Close the stopcock or isolation valve first to stop the water, then send a short video on WhatsApp so the plumber arrives with the right parts. Emergency call-outs start from S$80.
Who pays for a ceiling leak in an HDB flat?
Inter-floor seepage in HDB flats is treated as a shared responsibility between the upper and lower flat owners. Under HDB's Goodwill Repair Assistance scheme, repair costs are typically split between the two households. Diagnosis usually starts in the upper unit's bathroom floor slab or concealed pipes.
