Hiring an HDB-approved plumber is essential to ensure quality workmanship and compliance with regulations. After all, hiring an unqualified plumber can result in expensive repairs and possible penalties, as not all plumbers are permitted to perform plumbing work in HDB apartments.
Discover how to check for an HDB plumber in Singapore and learn why such a credential matters.
Why You Need an HDB-Approved Plumber
Plumbing work in HDB flats must be carried out by an HDB-approved plumber to ensure the safety and durability of the plumbing system. Approved plumbers are registered under the PUB (Public Utilities Board), which ensures they meet the required standards. Using a non-approved plumber may result in poor craftsmanship, water leaks, or even legal consequences if the work does not comply with HDB regulations.
Hiring an HDB plumber guarantees that repairs and installations adhere to the government’s plumbing codes. Whether fixing leaks, replacing pipes, or installing sanitary fixtures, an HDB-approved plumber ensures compliance, reducing the risk of rework or additional costs. If you require immediate assistance, many 24-hour plumbers offer emergency services while also being HDB-approved.
Steps to Verify If Your Plumber is HDB-Approved
1. Check the Official PUB Website
The easiest way to verify an HDB-approved plumber is by checking the PUB’s official website. PUB maintains an updated list of licensed plumbers who are authorised to work on HDB flats. To verify:
- Visit the PUB Licensed Plumber Directory on the official website.
- Search for the plumber’s name or the plumbing company they represent.
- Confirm if the plumber is listed as licensed and currently active.
If the plumber is not listed, they are not approved to perform HDB plumbing works.
2. Ask for Their License Number
Every HDB plumber should have a valid PUB license number. You can request this number directly from the plumber or the plumbing company. A legitimate plumber will provide their license details without hesitation. Compare the license number with the PUB directory to ensure it matches the records.
Some 24-hour plumbers in Singapore claim to be HDB-approved, but it is always best to verify their credentials before engaging their services, especially for emergency repairs.
3. Verify Company Registration with ACRA
If you are hiring a plumbing company, check if they are registered with the Accounting and Corporate Regulatory Authority (ACRA). ACRA registration ensures the company is legally operating. You can search for the company’s registration details using the BizFile+ website.
While ACRA registration does not confirm HDB approval, it helps validate the legitimacy of the plumbing company. Always ensure the plumber they send is personally HDB-approved.
4. Look for Past Customer Reviews and References
A reputable HDB-approved plumber will have reviews or references from past clients. Check Google Reviews, social media pages, or websites where customers leave feedback. Reviews can indicate whether the plumber has a history of performing quality work on HDB flats.
Negative reviews about faulty plumbing installations, leaks, or poor service should be red flags. Some 24-hour plumbers advertise quick response times but may not be HDB-approved. Always cross-check credentials to avoid hiring an unqualified service provider.
5. Request for Official Invoices and Documentation
A professional plumbing company will always provide official invoices, contracts, or service reports. If a plumber refuses to provide documentation, it may indicate they are not HDB-approved.
For major repairs or installations, ensure that the plumber submits the necessary permits or compliance forms required by HDB and PUB. These documents serve as proof that the work is done by a qualified professional.
Risks of Hiring a Non-HDB-Approved Plumber
Hiring an unapproved plumber may result in:
- Non-compliance with HDB regulations, leading to penalties or required rectifications.
- Low-quality repairs that can cause leaks, water damage, or increased water bills.
- Lack of accountability, as non-licensed plumbers do not have to adhere to PUB’s quality standards.
- Higher costs in the long run due to poor craftsmanship requiring additional repairs.
A 24-hour plumber who is not HDB-approved may still perform emergency services, but for major HDB-related works, always ensure they are properly licensed.
Conclusion
Verifying a plumber and a plumbing contractor in Singapore is straightforward but critical. Always visit the PUB website, ask for the plumber’s licence number, confirm that they are registered as a business, look at client testimonials and insist on the right paperwork. You can guarantee HDB compliance and steer clear of hiring unqualified plumbers by taking these precautions. Selecting an HDB plumber guarantees dependable and legally compliant services, regardless of your plumbing needs—from routine maintenance to emergencies.
