Led by Experience. Driven by Detail.
Hi, I’m David Metcalfe, founder of DM Estimating. I’ve been in the construction industry since I was 17, starting out hands-on with a Level 3 Plumbing & Heating apprenticeship. After six years on the tools, I moved into an M&E estimating role — and I’ve never looked back. Over the years, I’ve had the opportunity to work on landmark schemes in London and across the UK, covering a wide range of sectors including:
These experiences have given me a deep, practical understanding of how buildings come together — and how to price them accurately and efficiently. At DM Estimating, I bring together that background in both installation and estimation to offer a service that’s reliable, responsive, and tailored to your needs. I know what it’s like to be on-site, under pressure, and up against deadlines — which is why I focus on clear communication, fast turnaround, and accurate numbers you can trust. Whether you need support with a single tender or an ongoing pipeline of work, I’m here to help.
