About Costable.
Our goal is simple: clear, reliable and accessible cost advice that helps you make confident decisions about your construction project.
Who we are
Costable was founded by a husband and wife team with over 15 years in construction and quantity surveying, much of it with one of the UK's top five main contractors.
We do not just price projects. We walk through every estimate with you personally, one on one, led by one of us. Clear cost breakdowns, honest risk flags, and budgets that are realistic before work begins.
We work fully remotely, which keeps us flexible and efficient without the overheads of a traditional consultancy. And because we are a small family business, you will always deal with one of us directly. We take pride in building long-term relationships with our clients.
