Key Takeaway

• Your home renovation cost in Singapore can be higher for a resale flat because hacking, rewiring, or pipe replacement each add their own line to the quote.
• Compare quotes line by line, and check whether light fittings, appliances, and GST are included before you set your budget.
• CPF savings don’t cover renovation, so you’ll need cash or a bank loan, which can be capped at six times your monthly income or S$30,000.
• CaseTrust-RCMA accredited firms can take up to 20% of the total as a deposit, backed by a deposit performance bond, with the rest paid in stages.
• If your HDB flat was built in 1997 or earlier, check for HIP before redoing your toilets, since toilet upgrading is a subsidised HIP option.

Introduction

Ask three firms to quote for the same renovation, and you can get three very different totals. The gap can come from what each quote includes, which materials each firm picked, and what it left out.

Knowing what drives the home renovation cost in Singapore helps you read those quotes with confidence. It also matters for cash flow. You can’t use CPF savings for renovation, so the money has to come from cash or a loan.

One big factor shows up before anyone writes a quote: the flat you’re starting with.

Why Do Renovation Costs Differ Between BTO, Resale and Condo Homes?

A resale flat can cost more to renovate than a new BTO of the same size, because there’s more to remove or replace before the new work starts. Your home renovation cost in Singapore depends on your scope and your flat’s condition. So an itemised quote for your own home is the number to plan with.

New BTO flats have no old finishes to remove, so your money goes into what you add, like carpentry and lighting.

In a resale flat, some work comes before the fun part. Old tiles may need hacking (breaking out), and older wiring or pipes may need replacing. Each of these becomes its own line in the quote, on top of the design work you wanted.

Living in a condo? Check the renovation rules set by your condo management (MCST) before you collect quotes, so every firm prices the same allowed scope.

If you’re comparing cost estimates you’ve seen online, check that they’re for the same flat type and condition as yours. Otherwise, you may be comparing a blank-slate BTO with a resale flat that needs extra work.

Should Older Flats Wait for HIP Before Renovating?

If your HDB flat was built in 1997 or earlier, it may qualify for the Home Improvement Programme (HIP). So check before you spend on the bathroom.

Under HIP, Essential Improvements cover basic repairs. These include fixing spalling concrete (cracked, flaking concrete) and replacing old waste pipes. The government fully funds these for Singapore Citizen households.

Toilet upgrading sits under the Optional Improvements, along with a new entrance door and grille gate. For the full optional package, Singapore Citizen households pay only a small share of the cost:

If HIP is coming to your block, redoing your toilets first means paying the full price for work the programme would have subsidised.

What Drives the Price in an Interior Design Quotation?

An interior design quotation in Singapore lists the work trade by trade, so you can see exactly where your money goes. Here’s what each main line item covers and what can push it up:

When two quotes differ, compare them line by line. The gap can come from one trade rather than the whole job. Also check whether each quote includes design work, since some firms only build. This guide to renovation and interior design explains what each one covers.

A lower total can still cost you more later. This look at why affordable and cheap aren’t the same covers what to watch for when one quote looks far cheaper than the rest.

A lower quote can still lead to a pricier renovation. Any work missing from the quote still has to be paid for if you need it later.

Which Costs Might Not Be in Your Renovation Quote?

Some costs sit outside the renovation quote, so check what’s included before you fix your renovation budget in Singapore. Look out for these:

• GST may be added on top if the firm is GST-registered, so check whether the total includes it.
• Light fittings may be missing, since a quote can cover the wiring but not the lights themselves.
• Appliances such as the oven, hob and hood may be bought separately, even though your carpentry is built around them.
• Aircon supply and installation can come as a separate quote.
• Curtains, blinds and loose furniture may not be included either.
• Cleaning after the work ends may cost extra.

It also helps to keep a buffer for surprises. Hacking in an older flat can uncover problems, and those fixes won’t be in the original quote.

How Do Deposits and Progressive Payments Affect Your Budget?

Progressive payments spread the cost across the project, so you don’t pay everything upfront. Under the CaseTrust scheme for renovation businesses, accredited firms cap the first deposit at 20% of the total. They also have to buy a deposit performance bond, which protects your deposit if the business closes. MJS Interior holds this accreditation.

Staged payments still need money ready at each stage. If you take a loan, plan around its limit. One major bank lets you borrow up to six times your monthly income or S$30,000, whichever is lower (as of October 2026). It also asks for a signed, itemised renovation quotation, so check your own bank’s terms before you plan around a figure.

Before you sign, map each payment stage against your cash flow. This step matters if your furniture and appliances fall due around the same time.

Staged payments protect your deposit, but they don’t fund the renovation. Each stage still needs cash or loan money ready when it falls due.

How Much Should You Budget to Renovate a Home in Singapore?

Budget for the full scope, not just the quote total. Start with your flat and its condition, then add the trades you need and your choice of finishes. After that, add the costs outside the quote, like appliances and lighting. Finally, line up cash or a loan for each payment stage before you sign.

Frequently Asked Questions

1. Why can two interior design quotations in Singapore differ for the same flat?

They may not cover the same work. One quote might include design, hacking, or electrical works that another leaves out, or use different materials. Ask both firms to quote from the same layout and list of works, then compare each trade side by side.

2. Is the home renovation cost in Singapore higher for a resale flat?

It can be. Still house-hunting? Get a rough renovation estimate for that unit before you commit. That way, the flat price and the renovation together still fit your plans.

3. Should I pay the full renovation amount upfront for a discount?

Paying in stages keeps more of your money protected while work is in progress. If something goes wrong midway, you haven’t already paid for work that isn’t done. Ask how the firm ties each payment to a stage of work before you sign.

4. Does HIP replace my own renovation?

No. HIP covers a set list of repairs and optional upgrades, such as toilet upgrading. Your carpentry, kitchen and lighting are still part of your own renovation.

5. Can I change my design after signing the contract?

Yes, but each change (called a variation) can affect the price. Under the CaseTrust scheme, you and the firm have to agree each variation in writing before the work starts. Ask for the cost of each change on paper before you say yes.

A renovation budget gets easier to plan once you see where the money goes. Your flat’s condition sets the starting point, and the quote shows how each trade adds up. The extras outside the quote then decide whether your renovation budget in Singapore holds. Getting these clear early stops the home renovation cost in Singapore from surprising you halfway through the build.
