What Happens If the QS Estimate Is Higher Than My Budget?

You’ve found the perfect section. Your builder’s keen. You’re working through the bank paperwork.

Then — curveball — the QS estimate lands... and it’s higher than your budget.

Breathe.

This situation is more common than you think — and it doesn’t mean your build is off the table. In fact, it’s often just a case of “apples vs oranges.”

In this short guide, we’ll explain:

• Why QS estimates are sometimes higher than builder quotes

• What the bank is really looking for

• What you can do if the numbers don’t match your expectations

• And how to move forward without delays to your First Home Grant or construction loan.

  
  

What the QS Is Actually Estimating?

Let’s clear something up straight away — a Quantity Surveyor’s (QS) estimate isn’t designed to match your builder’s quote.

It’s designed to satisfy your bank.

That means it includes things your builder might not have priced — like professional contingencies, staged funding logic, and risk factors lenders want to see accounted for.

While a builder quote is a sales document, a QS estimate is an independent, third-party validation of your project’s financial reality.

Think of it as the blueprint your bank relies on to say:✅ “Yes — we’ll fund this.”

Not because they don’t trust you — but because they have to trust the numbers.

Why the Estimate May Be Higher Than Your Budget

When a QS estimate comes in above your budget, it’s not a mistake — it’s a reflection of what the bank needs to see to safely lend on your build.

Here’s why the number might look bigger than expected:

• Contingencies are required Most reports include a standard contingency (often 10%) to cover unknowns like price shifts or delays.

• Escalation factors are real Central Otago costs move fast — QS reports include escalation margins for longer build timelines.

• Bank forms are structured differently Each lender has its own reporting style — these don’t always match builder quotes, so figures can appear larger.

• Your builder may have excluded items Driveways, landscaping, curtain rails — a QS includes it all so there are no funding gaps later.

📌 This isn’t about inflating numbers — it’s about protecting your funding. If the bank can’t see the full cost, they can’t approve the full loan.

What the Bank Really Wants to See

When a bank asks for a QS report, it’s not to make life harder — it’s to protect everyone involved: you, the builder, and the lender.

They’re looking for:

• ✅ Clarity – A full, itemised breakdown

• ✅ Realism – Safe, achievable numbers

• ✅ Independence – Third-party objectivity

• ✅ Template Compliance – Matching ANZ, ASB, BNZ formats

• ✅ Funding Certainty – Clear staged drawdown logic

🔍 The bank isn’t saying no — they’re saying, “Help us say yes, confidently.”

What You Can Do If the Estimate Feels Too High?

First things first — don’t panic and definitely don’t abandon the build.

A higher QS estimate doesn’t mean the project is unaffordable — it just means a deeper look is needed.

Here’s what to do:

• Talk to your QS – We’ll walk you through it line by line

• Check your scope – Are extras bumping the number?

• Review the builder’s quote – Is it missing key costs?

• Adjust the timeline or finishes – Swap, stage, or simplify

• Explore bank flexibility – Some offer equity top-ups or guarantor support

💬 The takeaway? Your QS estimate isn’t a dead-end — it’s a map. Let’s use it to navigate, not stall.
