Why the way you ask for quotes matters
A quantity surveyor (QS) can help with budgeting, cost estimating, tender analysis, progress claims, variation assessment, and final account work. But quotes for QS services can vary a lot depending on the scope, the stage of your project, and how clearly you brief the provider.
If you simply ask, “How much for a QS?”, you may get very different answers because one firm may be pricing a basic estimate, while another is including detailed cost planning, trade breakdowns, site meetings, and contract administration support. The goal is not just to get a low figure — it’s to get a quote that matches what you actually need.
In New Zealand, that matters because construction costs, lead times, and labour availability can shift quickly. A well-scoped QS engagement can help you make better decisions before you commit to a builder or sign a fixed-price contract.
First decide what you want the quantity surveyor to do
Before seeking quotes, write down the exact service you need. A QS may be involved at one or more stages:
- **Feasibility or concept stage**: rough cost plan, budget check, early advice on affordability - **Pre-tender stage**: detailed estimate, schedule of quantities, value engineering ideas - **Tender stage**: review and compare builder quotes, check allowances and exclusions - **Construction stage**: assess variations, progress claims, cost reports - **Completion stage**: final account review and close-out
For a renovation or new build in NZ, a clear brief helps avoid “scope creep” later. For example, if you only need a pre-build estimate for a kitchen and bathroom renovation, you probably do not need monthly cost reporting or full contract administration.
When you ask for quotes, include:
- The property address and region - Type of project: new build, renovation, extension, remediation, or commercial fit-out - Approximate floor area in square metres - Current stage of design or consent process - Whether plans/specifications are complete or still being developed - Your budget target and any non-negotiables - Any deadlines, such as needing advice before council consent lodgement or before tender closing
The clearer your brief, the more useful the quote will be.
What a good QS quote should include
A professional quote should make it easy to understand what is included, what is excluded, and how the fee may change if the scope changes. Good quotes are usually written, not just given over the phone.
Look for these details
| Item | Why it matters | |---|---| | Scope of services | Tells you exactly what the QS will do | | Deliverables | Shows what you will receive, such as a cost plan, estimate, or report | | Assumptions | Reveals what the price is based on | | Exclusions | Prevents surprises later | | Fee structure | Fixed price, hourly rate, stage-based fee, or percentage | | Disbursements | Travel, printing, courier, software, or other extras | | Timing | When the work will be delivered | | Revision policy | Clarifies whether updates or rework are included | | GST | Confirms whether the quoted amount is plus GST or GST-inclusive | | Terms and conditions | Sets out payment timing, liability, and cancellation terms |
A good quote should also say what information the QS needs from you. If they are estimating from concept plans only, the quote should say the result is an indicative estimate rather than a fully detailed tender analysis.
How to request quotes the right way
To compare QSs fairly, send the same information to each one. That keeps the pricing more comparable and reduces the chance that one quote looks cheap simply because it leaves things out.
Your request should include:
- A short project summary - Drawings, specifications, or concept plans if available - A list of the QS services you want quoted separately - The expected timeframe - Whether you want a fixed fee or are open to charge-up pricing - Any required credentials, insurance, or membership standards
It can help to ask each provider to quote on the same basis, for example:
- Option A: feasibility estimate only - Option B: feasibility + pre-tender estimate - Option C: full service through to final account
That makes it much easier to compare value, not just numbers.
If your project may need council consent, be clear about where the QS sits in the process. A QS does not replace the need for a designer, engineer, plumber, electrician, or other licensed tradesperson where their work is required. For example, plumbing, gasfitting, and drainlaying are restricted under the PGDB regime, and electrical work is regulated by the EWRB. Building work may also require a building consent from your local council, depending on the scope.
Fixed price vs charge-up: which is better?
QSs in New Zealand may quote on a fixed fee, hourly rate, stage fee, or a mix of these. Each has pros and cons.
Fixed price
A fixed-price quote means you know the fee upfront for the agreed scope.
**Best for:** - Clearly defined jobs - Homeowners who want budget certainty - Projects with complete plans and a stable brief
**Watch for:** - Narrow exclusions - Extra charges if plans change - Limited revisions - Assumptions that reduce accuracy
A fixed price is only useful if the scope is genuinely clear. If the brief changes after the quote, expect the fee to change too.
Charge-up or hourly rate
Charge-up pricing means you pay for time spent, usually at an hourly or daily rate.
**Best for:** - Early-stage projects with incomplete information - Complex disputes or variations - Work where the scope is hard to define in advance
**Watch for:** - Less budget certainty - Time spent can grow if the brief is vague - You should ask for an estimate of hours and a cap, if possible
A charge-up arrangement can be fair, but only if the QS tells you the rate, expected hours, and when they will seek approval if costs rise.
A practical approach
For many homeowners, the best option is a hybrid:
- fixed fee for a defined deliverable, such as a pre-tender estimate - hourly rate for additional advice, variations, or scope changes
That gives you more certainty while still allowing flexibility if the project evolves.
How to compare quotes fairly
The cheapest quote is not always the best value. Compare the scope and assumptions first, then the fee.
When reviewing QS quotes, ask:
- Are they pricing the same service? - Do they include site visits, meetings, and phone support? - Are revisions included if the design changes? - Will they liaise with your architect, designer, builder, or engineer? - Are GST and disbursements included? - What reports or documents will you receive? - How experienced are they with similar NZ projects?
If one quote is much lower, it may be because it excludes important tasks like attending tender interviews, reviewing builder exclusions, or updating estimates after design changes. Those extras can become costly later.
It is also worth checking whether the QS has relevant experience in your type of work. A person who mainly does large commercial projects may not be the best fit for a villa renovation, and vice versa. For residential work in NZ, experience with local building costs, consent processes, and common construction methods is valuable.
Warning signs that a quote is too cheap
An unusually low quote can be a genuine discount, but it can also mean the scope is incomplete or the provider is underpricing to win work.
Be cautious if the quote:
- Is vague about exactly what is included - Has no exclusions or assumptions listed - Does not mention GST - Promises a fully detailed service for a price that seems far below the others - Relies heavily on “estimate only” language without explaining limitations - Offers no revision policy - Does not ask questions about your plans or specifications
A too-cheap quote often becomes expensive later when extra meetings, redesigns, or re-estimating are billed as extras. Sometimes the lowest quote also comes from someone who has not properly allowed for the time needed to do the job well.
On the other hand, a higher fee can still be good value if it includes better scope, more experience, clearer reporting, and fewer surprises. What you want is a quote that is realistic, not just low.
Check credentials before you commit
A QS does not need a single government licence in the same way as an electrician or plumber, but you should still check their qualifications, experience, and professional standing.
Useful checks include:
- Relevant quantity surveying or construction cost management qualifications - Experience with projects similar to yours - Insurance, especially professional indemnity insurance - Membership of relevant professional organisations, if applicable - References from recent NZ clients - Clear written terms and a legitimate business address
If the QS will also be dealing with contract claims, variations, or payment certifications, ask about their experience with NZ building contracts and dispute processes. That can matter if a project becomes contentious.
Questions to ask before choosing a QS
These questions help you compare providers on more than price:
- What exactly is included in your fee? - What assumptions have you made about the project? - How many revisions are included? - Will you visit site, or is the service remote only? - How do you handle variations to the scope? - What happens if the design changes after your estimate is issued? - Do you work on fixed fee, charge-up, or both? - What deliverable will I receive at the end? - How soon can you start, and how long will it take? - Do you carry professional indemnity insurance?
If the answers are clear and consistent, that is a good sign.
A simple process for homeowners
A sensible quote process for NZ homeowners looks like this:
1. Define the QS service you need. 2. Gather plans, photos, scope notes, and deadlines. 3. Send the same brief to at least three providers. 4. Ask for written quotes with GST, assumptions, exclusions, and deliverables. 5. Compare like-for-like, not just headline fees. 6. Check experience, insurance, and responsiveness. 7. Choose the quote that offers the best combination of clarity, value, and fit.
For renovations and new builds, the right QS can help you avoid budget blowouts and make better decisions before you sign contracts or start work. The key is to brief them well, compare quotes carefully, and be wary of pricing that looks too good to be true.
