Renovation Quotation Checklist: What to Check Before You Sign

What isn't written down is what you'll argue about later. Use this checklist on every quotation before you sign.

What a clear quotation includes

The Competition and Consumer Commission of Singapore (CCCS) published a fair trading guide for the renovation industry. It covers five areas, and each one is something to look for in your quote:

What each line should tell you

For every item, you should be able to answer four questions: what, where, how much, and what it's made of.

VagueClear
Kitchen cabinet – lump sumKitchen bottom cabinet, 3.2 m run, plywood carcass, [brand] laminate, soft-close hinges, [brand] quartz top
Hacking – TBCHack kitchen wall between kitchen and living, approx. 2.4 m, including PE endorsement and debris disposal
Floor – vinylVinyl strip flooring, [brand/series], 4 mm, living and 3 bedrooms, approx. 65 sq m, including skirting

The examples are illustrative. The point is that sizes, materials, brands and inclusions are written down.

6 words that cost you later

Word in the quoteWhat to ask
“Lump sum”What's inside it? Ask for sizes, materials and quantities.
“TBC”What's the likely price range? Get it in writing.
“Approx.”How will the final size be measured, and how will it be charged?
“Tiles up to $X psf”This is an allowance. What will an upgrade cost?
“Selected laminate”Which brand and series?
“Inclusive”Inclusive of what, exactly?

Questions to ask, section by section

What's often not in the quote

Ask the ID to confirm, in writing, whether each of these is included:

How to compare 2–3 quotes fairly

A lower total with more “TBC” items can end up costing more than a higher, clearer quote.

Variation orders (VOs)

A variation order is any work added to, or removed from, the signed quotation. Small VOs add up quickly. CaseTrust's standard renovation contract requires cost variations to be agreed in writing.

FAQ

Can I ask for changes to the quotation before signing?

Yes. Ask for vague items to be itemised, and for anything verbal to be written into the quote. A good firm will do this without fuss.

Is a lower quote always better?

No. Check what's missing and how many items are “TBC”. The cheapest quote often grows the most through variation orders.

What is PE endorsement?

For some hacking works, a Professional Engineer must endorse the plans. Ask whether it's needed for your works and whether it's included in the price.

Can you review my quotation?

Yes. Quotation review is an add-on to our consultation. WhatsApp us with your quote for a fee.
