Get to know us


David Hill, boasting over 35 years of experience in both the public and private sectors, has played a pivotal role in the development of over 5000 homes. His recent projects include 1100 low-energy units achieving 40-100% carbon reductions compared to 2002 Building Regulation standards. In 2009, he founded Carbon Legacy to push the envelope in zero-carbon housing solutions, marking significant milestones with the development of the first zero-carbon Code 6 homes in Upton, Northamptonshire, and leading the first zero-carbon refurbishments in East Leake, Nottinghamshire.

His efforts also extended to introducing the UK’s first commercial buildings equipped with ground-sourced heat pumps at Raleigh Square, Nottingham. Under his guidance, Carbon Legacy has flourished, focusing on carbon emission reduction and operational cost savings. The company has made significant strides in sustainability, including electrifying its vehicle fleet and expanding its office space in 2022/23 to accommodate a growing team and workload.


Shirley Mills plays a crucial role in our business success, serving as a warm and approachable point of contact for both customers and staff. She is instrumental in efficiently overseeing and directing a wide range of business processes, ensuring the smooth delivery of our services.
