FAQs — PUB Licensed Plumber Singapore
What does a PUB licence mean for a plumber?
A PUB (Public Utilities Board) licence means the plumber or company is legally authorised to carry out water supply installation, sanitary plumbing and drainage works in Singapore. It is illegal for unlicensed contractors to perform these works. AOT Trinity holds a valid PUB licence — you can request verification before work begins.
How is AOT Trinity different from plumbing-only companies?
AOT Trinity is a PUB-licensed multi-trade contractor. Unlike plumbing-only firms, we also handle aircon servicing, electrical works, water heater installation, pumps and tanks — all under one contract. This means you get better coordination, fewer contractors on-site, and significant savings on bundled jobs.
Is there an emergency plumber available at night?
Yes. AOT Trinity operates 7 days a week for emergency plumbing calls including burst pipes, severe drain blockages and flooding. Call 6816 2462 or WhatsApp 8151 8857 for immediate dispatch.
What is the cheapest plumber in Singapore?
AOT Trinity's plumbing services start from S$50 for drain unblocking and S$60 for pipe leak repairs — among the most competitive rates for a fully licensed contractor in Singapore. Pricing is transparent and quoted upfront before any work begins.
Does AOT Trinity serve condominiums and offices?
Yes. We handle all property types — HDB, executive condominiums, private condos, landed homes, shophouses, offices and industrial units across Singapore.
