Top 10 Best Plumbing Services in Singapore
Alpha & Omega Trinity Pte Ltd, commonly known as AOT Singapore, is a mechanical and electrical contractor incorporated on 25 June 2012. The company provides plumbing, electrical, air conditioning, water heater and building maintenance services for residential and commercial properties.
Its plumbing capabilities include water service installations, concealed piping, sanitary works, water pumps, storage tanks and projects requiring PUB submissions. The company also serves MCST-managed developments and property managers seeking coordinated building maintenance services.

It also identifies its BCA ME12 Grade L1 registration, UEN 201215586K and bizSAFE Level 3 credentials.

What Makes Alpha & Omega Trinity Stand Out

Water Pump and Tank Expertise: Its services extend to water pumps, storage tanks and associated water supply infrastructure.
Integrated M&E Capabilities: The company combines plumbing with electrical, air conditioning, water heater and other building maintenance work.
Building and Regulatory Work: AOT handles plumbing-related PUB submissions and advertises BCA contractor registration, making it relevant to certain regulated and building-related projects.
Ideal For: Homeowners, landlords, MCSTs and commercial property managers requiring plumbing contractors with published licensing details and capabilities extending into water pumps, tanks and other M&E systems.
