Renovation Payment Schedule in Singapore: Deposits, Progressive Payments and Retention
Almost every renovation argument we have ever been called in to look at started as a payment argument. Not a taste argument, not a workmanship argument — a disagreement about who owed what, at which point, and what the money was supposed to have bought.
The reason is that most homeowners sign a quotation that specifies the work in detail and the payment in one line. The scope runs to four pages; the payment terms run to nine words. Then the job starts, and the nine words are the only part anyone refers to again.
This is how renovation payments are structured in Singapore, what each stage is meant to be paying for, and the specific clauses that decide whether you have leverage or not.
The principle: money follows completed work
A renovation payment schedule exists for one reason — to keep the amount you have paid roughly level with the amount of work that has actually been finished. Not started, not ordered, not delivered to site. Finished.
When that alignment holds, both sides are protected. The contractor is never funding your project out of his own pocket, and you are never so far ahead that walking away costs you more than staying. When it breaks — and it usually breaks in the homeowner's direction, because the payments are front-loaded — you have paid for a house that is half built and you have nothing left to withhold.
Everything below is a way of testing that one principle against a real quotation.
The deposit, and the number that should make you stop
The first payment is booking money. It covers mobilisation, the ordering of long-lead items, and the contractor's commitment of a slot in his schedule. It is legitimate, and it is not supposed to be a large share of the contract.
As we say in our guide to reading and comparing renovation quotations: do not pay more than 20% upfront unless there is a large custom order genuinely requiring advance payment, such as imported stone. A contractor asking for a 50% deposit is either short of cash or has a different plan for it. Either way the risk lands on you.
If a big deposit is being asked for because of a specific material order, ask for the supplier's invoice. A real long-lead item has a paper trail. A number that exists only in the quotation does not.
The middle stages: what each one should be tied to
Between deposit and handover, the payments should attach to events that either of you can see and neither of you can argue about. In a typical Singapore residential renovation those events are:
- Hacking and demolition complete. The flat is stripped, debris is cleared, and the shell you are actually building on is visible for the first time.
- Wet works complete. Masonry, screeding, waterproofing and tiling done. This is the stage where hidden defects become permanent, which is why it deserves an inspection and not just a payment.
- Carpentry installed. Usually the largest single line in a residential quotation, and the stage where "delivered to site" and "installed and functioning" are very different things.
- Mechanical and electrical complete. Points live, lights working, plumbing tested, everything tested rather than merely wired.
- Practical completion and handover. Works finished, site cleaned, keys and any warranties handed over.
The wording matters more than the count. "Upon commencement of carpentry" is a date. "Upon completion of carpentry installation" is an achievement. Only one of them is something you can verify before releasing money, and it is worth insisting the schedule is written in the second form throughout.
Retention: the clause that makes defects get fixed
The single most useful thing you can negotiate is not a lower price. It is retention.
Holding back 10–15% until defects are rectified is what gives a contractor a reason to come back after you have moved in. Once the final payment has cleared, the only thing bringing anyone back to your flat is professionalism — which most contractors have, and which is a thin thing to rely on when a door is not closing properly and everyone is already on the next job.
Two details make retention real rather than decorative. First, it must be written into the payment schedule, not agreed verbally. Second, there must be a defined release trigger — a defects period with an end date, after which the balance is due. Open-ended retention is unfair to the contractor and, in practice, tends to get quietly abandoned, which helps nobody.
What retention is not is a substitute for a warranty. Our guide to what a renovation warranty should cover sets out the difference.
Variation orders: where budgets actually break
Nothing breaks a renovation budget like changes agreed in a WhatsApp message and priced after the fact. A variation order is any change to the agreed scope, and it is the most common route from "the quotation said $X" to a final bill that does not resemble it.
The discipline is simple and it protects both sides. Any change is written down, priced, and accepted before the work is done. The variation says what is being added or removed, what it costs, and whether it moves the completion date. If it affects the payment schedule, that is stated too.
This is not bureaucracy for its own sake. A homeowner who approves four verbal changes over six weeks will genuinely not remember agreeing to the third one, and neither will anyone else. The written variation is what stops that becoming a dispute at handover.
The costs that sit outside the payment schedule
Several real costs in a Singapore renovation are not contractor payments at all, and they surprise people because they fall due at inconvenient moments.
For HDB flats, the renovation permit is applied for by the licensed contractor — ours is HB-09-5667H — and the conditions attached to it govern hacking, timing and noise. For condominiums, the MCST typically charges an admin fee of around S$200–500 and holds a refundable renovation deposit of roughly S$2,000–5,000, which is your money sitting with the management until the works are signed off. If those items are not on your quotation, ask who is paying them rather than assuming. The condo renovation rules and MCST approval guide covers the process.
Then there are the costs of the household itself — storage, temporary accommodation, or the compromises of living in the flat while the works run. None of these appears in a payment schedule, and all of them appear in real life.
Paying in a way you can prove
Pay the company, not a person. Bank transfer to the company account, or a cheque made out to the company, leaves a record that matches the contract. Cash paid to an individual on site does not, and if there is ever a disagreement about whether a stage was paid, the record is the entire argument.
Keep the quotation, the signed payment schedule, every variation order and every payment receipt in one place. It sounds like advice for a business rather than a home. It takes about ten minutes in total, and it is the difference between a conversation and a dispute.
What we do, and why it is arranged this way
We are a direct contractor. There is no interior designer between you and the people doing the work, and our carpentry is made in our own factory at 19 Kaki Bukit Industrial Terrace rather than bought in — which is why carpentry, usually the biggest stage payment in a renovation, is a stage we control end to end rather than one we are waiting on a third party to deliver.
We quote from the scope after a site visit, itemised, so that each payment stage is attached to work you can point at. If a stage in a schedule cannot be explained in one sentence that a non-builder would accept, it is written wrongly — ours included.
Before you sign, check these six things
- The deposit is 20% or less, or there is a supplier invoice explaining why it is not.
- Every stage is worded as a completion, not a commencement or a calendar date.
- Retention of 10–15% is written into the schedule, with a defined defects period and release date.
- Variation orders must be written and priced before work proceeds — and that is stated in the contract.
- Permit and MCST costs are allocated to somebody in writing.
- All payments go to the company, by traceable means.
Six lines. They cost nothing to insist on before signing and are close to impossible to add afterwards.
Send us the quotation you are looking at
If you have a quotation in front of you and the payment terms are one line, send it over. We will tell you plainly which stages are missing, whether the deposit is reasonable, and what we would want changed before signing — whether or not the quotation is ours. As a direct contractor we quote from the scope after a site visit, itemised.
