It’s one of the first practical questions anyone asks once they’ve decided they actually need a quantity surveyor. You’ve got the budget concerns, the tender to price, or the cost plan to build, but before any of that, there’s a more immediate one sitting in your inbox: what is this going to cost me?

Fair question, and one that doesn’t have a single tidy answer, because “hiring a QS” can mean several quite different things depending on how you go about it. Here’s what actually drives the cost, and where the real savings are hiding.

The Traditional Route: Hiring Locally

The conventional approach is hiring a quantity surveyor directly, either as a permanent employee or bringing in a local consultant on a project basis. In Ireland, an experienced QS working locally typically commands a salary or day rate that reflects the local cost of living, professional overheads, and demand for QS talent, which has been consistently high in recent years.

For a single project or a smaller developer, hiring a full-time QS often doesn’t make financial sense, the workload simply isn’t there to justify a permanent salary. That leaves project-based consultancy as the usual alternative, which solves the commitment problem but still comes with a day rate that reflects the same local cost base.

Why the Number Varies So Much

The cost of a quantity surveyor depends heavily on experience level, project complexity, and whether you’re engaging someone for a single service, like a cost estimate or a BOQ, versus ongoing project support through the full build. A junior QS supporting take-offs costs considerably less than a senior QS managing final accounts and contractual risk on a complex commercial scheme. Location matters too. Dublin rates and rural rates for the same level of experience aren’t the same number.

“How much does a QS cost” doesn’t have a single answer that applies to every project. The honest answer is: it depends on what you actually need, and for how long you need it.

The Alternative: Remote QS Support

This is where the model has genuinely shifted for a lot of Irish developers and contractors in recent years. Remote quantity surveying, engaging an experienced QS team working remotely rather than locally, delivers the same professional standard of work at a significantly lower cost, because it strips out the overhead of local hiring without compromising on quality or oversight.

At SwiftCore, our remote QS model consistently delivers over 60% in cost savings compared to hiring an intermediate quantity surveyor locally, while still providing Ireland-based oversight and the same level of accuracy and turnaround you’d expect from an in-house hire. We’ve completed more than 250+ BOQs across housing, commercial, education, and data centre projects, with a 99 percent on-time delivery rate, so it’s not a trade-off between cost and quality, it’s simply a smarter delivery model.

What the Delivery Model Actually Looks Like

“Remote” doesn’t mean handing over your drawings and hoping for the best. In practice it’s a structured process:

• Briefing. Every engagement starts with a proper scoping conversation, what’s needed, by when, and to what level of detail, so the team is working from the same brief a locally hired QS would be given.
• Integration with your processes. The team works within your existing workflows, document formats, and reporting cadence, rather than asking you to adapt to theirs. Output slots into your systems the way an in-house hire’s would.
• Ireland-based oversight. Every deliverable, whether it’s a cost plan, a BOQ, or a final account, is reviewed and signed off in Ireland before it reaches you, so you’re never dealing with unchecked offshore output.
• QA/QC. A structured review sits behind every piece of work, checking measurement accuracy, pricing assumptions, and consistency before anything ships, which is what underpins the 99% on-time delivery rate across the 250+ BOQs completed to date.
• Communication. You get a consistent point of contact and regular check-ins through the life of the project, so there’s no black box between briefing and delivery, and no surprises when the numbers land.

That combination, local accountability wrapped around a remote delivery team, is what makes the cost savings possible without asking you to compromise on how the work is managed.

So, What Should You Actually Budget For?

If you’re comparing options, it’s worth pricing out both routes properly rather than assuming local hire is the only path. Ask what’s actually included in a quoted rate, whether it’s a single deliverable or ongoing project support, and what level of experience you’re getting for that price. Then compare it against a remote QS model that can flex up or down with your project’s actual workload, rather than committing to a fixed local cost regardless of how busy the project actually is.

“How much does a QS cost” in isolation matters less than “how much does a QS cost relative to what I actually need done.” That’s a conversation worth having before you commit to either route.
