For estate agents
We run our Project Calculator free of charge on any property or plot you are marketing, so your buyers have the build cost confidence to move forward and you close more sales.
Why deals stall
When a buyer views a property that needs significant work, or a plot with planning permission, they almost always ask the same question: what would it actually cost? Without a credible answer, deals stall. Buyers hesitate. Some walk away entirely, not because they cannot afford it, but because they cannot see clearly what they are committing to. We fix that, quickly, professionally and at no cost to you or your buyer.
What you get
A professional cost indication based on the property or plot, the scope of works and local market rates. Not a guess, not a national average. A number your buyer can rely on.
An honest view of how long the build or renovation would take, so buyers can plan their move and their financing with confidence.
The Project Calculator figure is free at enquiry stage. Your buyer commits to nothing. If they want to go further, we offer a full Feasibility Study at a reduced rate for estate agent referrals.
How it works
Send us the property address and a brief description of what the buyer has in mind. That is all we need to get started.
Within two to three working days you have a clear, written build cost range and programme your buyer can read and understand.
We send it directly, or back through you, whichever works best. Your buyer now has the information they were missing. You close the sale.

We will be in touch within one working day to confirm receipt. No obligation, no charge.
