If you’re planning a home extension, bringing a Quantity Surveyor (QS) into your team can save you time, stress, and money — before you even break ground.
Here’s how a QS adds value to your project:
At the design stage - A QS can help you understand approximately what your build costs are likely to be before you invest valuable time and money getting planning approval and building warrants. This gives you confidence that your project is affordable and realistic from the start.
At the tender stage - A QS can prepare a list of materials and quantities in the project, which you can send to multiple builders. This ensures all builders are pricing the same project and nothing gets missed, making comparisons accurate and fair.
Understanding builder quotes - A QS has a strong understanding of market rates and can help you spot whether a builder’s quote is unusually high or low — protecting you from overpaying or falling into a “too good to be true” situation.
In short: a QS helps you budget accurately, tender fairly, and spend wisely — giving you peace of mind and confidence at every stage.
