This includes residential developments, commercial buildings, industrial facilities, and condominium projects. The contract is essential for both new installations and modifications to existing systems. Property developers, main contractors, and individual homeowners all require this document when engaging licensed plumbing contractors. Given Singapore's emphasis on water security and building safety, no plumbing work should commence without a proper contract in place.

Licensing requirements are paramount—your contractor must hold valid PUB licenses and relevant certifications.

Additionally, include provisions for regulatory approvals, inspection schedules, and compliance with building codes.

Legal requirements in Singapore

Singapore's regulatory framework for plumbing work is comprehensive and strictly enforced. The Building Control Act requires all plumbing contractors to be licensed by PUB (Public Utilities Board) and registered with BCA (Building and Construction Authority). Your contract must comply with the Public Utilities (Water Supply) Regulations and incorporate requirements from Singapore Standard SS 636:2018 for water services. The Sewerage and Drainage Act governs drainage system installations, while the Building Maintenance and Strata Management Act applies to common property works. All plumbing work must receive proper approvals before commencement, and completion certificates are required for regulatory compliance. Your contract should reference these statutory requirements and ensure the contractor assumes responsibility for obtaining necessary permits and approvals.
