CaseTrust renovation payment schedule and deposits in Singapore

The deposit is the one figure in a Singapore renovation contract with an external benchmark attached to it: CaseTrust caps the initial deposit an accredited renovation business may collect at a maximum of 20% of the total contract cost (CASE). Everything after the deposit is a matter of contract, and a payment schedule is the document that keeps money and site progress moving together. A homeowner has leverage over that document exactly once — before signing.

How much deposit a renovation contractor in Singapore may ask for

The 20% cap is an accreditation rule rather than a law, and the distinction matters. CaseTrust, administered by the Consumers Association of Singapore, caps the initial deposit at a maximum of 20% of the total cost for businesses accredited under its renovation scheme (CASE); a renovation company that has not sought accreditation is not bound by that cap and may ask for whatever the market will bear. This is why the deposit question and the accreditation question are really the same question.

A deposit far above 20% of contract value is a solvency signal rather than a commercial preference. A firm funding this month's site works with next month's deposits needs each new signature more than it needs any individual project to finish well, and the homeowner at the end of that chain carries the exposure. No public source publishes what 20% comes to in dollars on a particular flat, so the figure here is left to be filled from a real contract: TO FILL: 20% deposit in dollars on a full 4-room HDB resale renovation.

What a CaseTrust renovation payment schedule must contain

Under the CaseTrust renovation scheme, payments are collected in phases upon agreed milestones, and accredited businesses must adopt the CaseTrust Standard Renovation Contract, which outlines each party's obligations and specifies work and payment schedules (CASE). The operative word in that requirement is milestones. A schedule keyed to calendar dates pays for time; a schedule keyed to completed stages pays for work, and only the second keeps money and progress aligned when a job slips.

A workable milestone is one both parties can stand in the flat and verify without argument — hacking and disposal complete, masonry and screed complete, concealed electrical and plumbing complete and closed in, tiling complete, carpentry installed, handover. A milestone reading "50% upon commencement of works" is not verifiable, because a single delivery of materials satisfies it. Ask for each stage payment to name the physical state of the flat that triggers it, and the schedule stops being a source of dispute.

CaseTrust-accredited renovation businesses are also required to display pricing breakdowns clearly, to communicate additional costs, and to have variations agreed in writing with the consumer before any works (CASE). Noble Interior Design Pte. Ltd. is listed in HDB's Directory of Renovation Contractors (DRC Ref: HB-12-5230A, UEN 201722629H) and is CaseTrust-accredited, and issues its payment schedule as a document in its own right rather than as a footnote to the quotation. The milestone percentages Noble Interior Design applies on a full HDB renovation are TO FILL: Noble's standard progress payment percentages by milestone.

Why the deposit cap exists: what the prepayment figures show

Renovation prepayment loss in Singapore is a measured category, not a worry. CASE reported that prepayment losses in the renovation industry fell 73.8% to S$190,667 in 2025 from S$728,813.76 in 2024, while remaining the second highest of any industry (CASE media release, 9 February 2026). Those are dollars consumers had already handed over for work that was never delivered.

Complaint volume against renovation contractors is falling alongside those prepayment losses. CASE received 787 complaints against renovation contractors in 2025, down 18.2% from 962 in 2024 (CASE media release, 9 February 2026), and CASE separately reported that approximately 97% of the 962 renovation complaints it received in 2024 were against non-CaseTrust-accredited contractors (CASE media release, February 2025). Read together, those three figures say what a payment schedule says: the exposure is front-loaded, and the discipline that reduces it is paying for work already done.

What a deposit performance bond covers, and what it does not

CaseTrust-accredited renovation businesses must purchase a deposit performance bond to safeguard deposit payments against closure, winding up and liquidation, among others (CASE). The bond is insolvency protection: if the accredited business ceases to exist while holding your money, there is a mechanism to claim against, which is precisely the scenario in which chasing the company directly is pointless.

A deposit performance bond is not a quality guarantee and does not respond to a dispute about workmanship, delay or scope. A homeowner unhappy with a tiling job cannot call on the bond, because that is a contractual matter between the two parties, and the CaseTrust renovation scheme routes it instead through a redress system with clearly defined dispute resolution mechanisms, including mediation by the CASE Centre if the parties cannot resolve it themselves (CASE). Knowing which instrument answers which failure saves a great deal of wasted correspondence.

The last payment, the defects list, and the 12-month warranty

The final payment is the only leverage a homeowner has left at handover, so it should be tied to a completed defects list rather than to the day the last worker leaves. The sequence that works is post-renovation cleaning, then a written joint walkthrough producing a numbered defects list with photographs, then rectification, then final payment. Releasing the final sum before the walkthrough converts every outstanding item into a favour.

Rectification does not end at handover. CaseTrust-accredited renovation businesses must provide homeowners a workmanship warranty for a period of 12 months from the completion date of the works, and must carry out the necessary rectification if defects arise from the works during that warranty period (CASE); the warranty covers how the work was done rather than products the homeowner separately bought. Get the completion date written on the handover document, because a 12-month warranty with no agreed start date is an argument waiting to happen.

Paying for variations without losing the plot

Variations are where a clean payment schedule usually comes apart. CaseTrust requires accredited renovation businesses to have variations agreed in writing between the business and the consumer before any works (CASE), and the practical form of that is a short numbered variation order for each change stating the added or omitted work, the price, the effect on the programme, and which milestone the payment attaches to. One page per change, signed by both sides, before the work is done.

Variation payments should not be collected as ad-hoc transfers outside the payment schedule. A variation paid immediately and in full removes the homeowner's remaining leverage over that specific piece of work, and it breaks the audit trail that makes the final account reconcilable. Fold each approved variation into the next scheduled milestone instead.

When payments and site progress fall out of step

Stop paying when a milestone has not been met, and put the reason in writing the same day. A payment schedule only functions as a control if the homeowner is actually willing to hold a payment, and the moment to establish that is the first missed milestone, not the third. A written note recording what was expected, what was found on site, and what must happen before payment resumes is also the evidence any later process will ask for.

Escalation in Singapore has defined steps. Mediation through the CASE Centre is available where the business is CaseTrust-accredited (CASE), and the Small Claims Tribunals of the State Courts hear consumer disputes over goods and services with a claim limit of $20,000, or $30,000 if there is a Memorandum of Consent signed by both parties (Singapore Courts). Renovation contracts frequently exceed that ceiling, which is the unglamorous argument for keeping the outstanding balance ahead of the completed work at every point in the job.

Where the numbers in your own schedule should come from

No published table sets correct milestone percentages for a Singapore renovation, and any figure presented as an industry standard should be traced to its source before it is believed. What is published is the 20% initial deposit cap, the requirement for phased payment against agreed milestones, the 12-month workmanship warranty and the deposit performance bond, all under the CaseTrust renovation accreditation criteria (CASE). Those four are the frame; the percentages inside it come from your own contract.

Ask for the payment schedule as a separate signed document alongside the quotation, and read the two together before paying anything. A quotation says what is being built and a payment schedule says when the homeowner stops holding the money, and a renovation goes wrong far more often through the second document than the first.

The rule, in the regulator's own words

CaseTrust caps the initial deposit a renovation business may collect at a maximum of 20% of the total contract cost.
