Why use a cost calculator?

Renovation costs are hard to estimate

Most property owners underestimate renovation costs or are surprised by unrealistic quotes. Our calculator provides a realistic guide.

Realistic cost range

Instead of a flat figure, receive a range from minimum to maximum costs, tailored to your property and desired standard.

Breakdown by trade

See at a glance how much each trade costs: façade, windows, bathroom, heating and more — broken down individually.

Basis for quotes

Use the cost range as a negotiating basis. Instantly recognise whether a contractor's quote is within range.
