All prices, quotations and estimates given by phone, WhatsApp, email, website or online messages are based on information available at that time. Final pricing may change after site inspection if the actual issue, access condition, parts required, manpower required, urgency, safety risk, concealed defect or service scope differs from the information first provided.

Our technician may inspect the site before confirming the final work scope and price. If additional work, parts or risks are discovered, we may provide a revised quote. The customer may accept or reject the revised quote, but inspection, transport, attendance or diagnostic charges may still apply where stated or agreed.

4. Authority To Instruct Work

The person confirming the booking or instructing the technician is deemed to have authority from the owner, tenant, occupier, managing agent or relevant party to approve the work and charges.

Customer Responsibility

Before Work Starts

Drilling, Cutting, Hacking And Wall Works

Where drilling, cutting, hacking, mounting or penetration works are required, there is a risk of cracks, chipped tiles, weak plaster, concealed pipes, concealed electrical wiring or hidden defects.

Electrical works are subject to applicable safety requirements. If an electrical condition is unsafe, our technician may stop work, isolate the issue, recommend further inspection, or decline to proceed until the risk is resolved.

Authority And Third-Party Requirements

No Retention Unless Agreed

The customer shall not withhold retention, set-off or deduction unless expressly agreed in writing by Alpha & Omega Trinity Pte Ltd. Full payment must be made according to the stated payment terms.

Waiting Time, Delay And Site Readiness

Customer-Supplied Or Third-Party Products

Where the customer supplies parts, appliances, fixtures, taps, heaters, pumps, tanks, electrical fittings or other materials, we are not responsible for product defects, compatibility issues, missing parts, manufacturer warranty, performance or future failure of those items.
