## Licences
- **Licensed Plumber (LP)** (PUB, Singapore's National Water Agency, required): Required for regulated water service work (laying, altering or replacing water pipes, tanks and fittings) and sanitary plumbing work (installing, changing or relocating toilet bowls and sanitary pipes). It is an offence to engage an unlicensed plumber for these works. Check: https://eservices.pub.gov.sg/bpp/searchlicensedplumber

## How to choose
- Decide if your job needs a licensed plumber: toilet bowl replacement, pipe rerouting and water tank work do; tap replacement, choke clearing and basin installation do not.
- Verify the plumber's name and licence number on PUB's online Licensed Plumber search before work starts.
- Ask for a fixed quote after diagnosis, including parts and transport, rather than an open-ended hourly charge.
- For HDB flats, any change to the original sanitary piping needs HDB approval, so use a DRC contractor working with a licensed plumber.
- Ask whether the plumber gives a workmanship warranty, especially for concealed pipe work.

## Red flags
- Unwilling to give a licence number for work that needs a licensed plumber.
- Quoting a low call-out fee, then adding large 'parts' or 'machine' charges after starting.
- Recommending replacement of all pipes without showing you the leak or damage.
- Cash-only with no invoice or business name.

## FAQs
### Do I need a licensed plumber to change a toilet bowl?
Yes. Installing, changing or relocating a toilet bowl is sanitary plumbing work that must be done by a PUB Licensed Plumber. Since 1 April 2018, it is an offence to engage someone who is not licensed for regulated water service and sanitary plumbing works. You can check a plumber's licence on PUB's online search.

### What plumbing work can a handyman do in Singapore?
PUB allows handymen to do simple plumbing works without a licence. These include replacing taps, mixers, shower hoses and showerheads, flushing cistern mechanisms, installing or replacing washbasins, sinks, bathtubs and shower trays, replacing floor trap gratings, and clearing blockages in floor traps, toilet bowls and sanitary appliances. Anything involving water pipes or toilet bowl replacement needs a licensed plumber.

### How much does it cost to clear a choked toilet in Singapore?
Published rates for clearing a choked toilet bowl range from about $60 to $300, depending on how severe the blockage is and whether the bowl needs to be removed. Clearing a floor trap, basin or sink choke is cheaper, at roughly $40–$150. Ask for the price before work starts and whether transport is included.

### How do I check if a plumber is licensed by PUB?
Use PUB's online Licensed Plumber search, which lists plumbers available for hire. Ask the plumber for their name and licence number and match it to the register. The Singapore Plumbing Society and Town Councils can also refer you to licensed plumbers.
