GS Kelsey Construction was established in the late 1990s by founder Geoffrey Snowden Kelsey, continuing a family legacy that dates back to the early 20th century.
The business traces its origins to Arthur Benjamin Kelsey, who operated a small contracting business in Crowle, North Lincolnshire, undertaking work for district councils, railways and local farmers.
Over the decades, successive generations of the Kelsey family have played a part in shaping the local built environment. In 1996, Geoff Kelsey, drawing on his experience as a quantity surveyor, continued this legacy by establishing a contractor built on reliability, professionalism and a commitment to quality, delivering new build, extension and refurbishment projects for local authorities and businesses.
Investment in the public sector during the early 2000s provided a platform for sustained growth, with the business expanding significantly over the following decade. In 2010, Geoff's son, Andrew, assumed leadership and further strengthened the company's position while maintaining its core principles.
Since then, GS Kelsey Construction has evolved into a modern, forward-thinking contractor while remaining grounded in its heritage. With an annual turnover in excess of £10 million, the company now operates across a range of sectors including education, social housing, healthcare, retail, commercial and leisure. While its strong presence in the public sector remains central, the business continues to diversify, guided by a commitment to its people, its values and the communities it serves.
In 2026, the business marks 30 years of trading, alongside key milestones including the receipt of its first national award and the delivery of two of the largest projects in its history, each exceeding £10 million in value. This period is marked by significant investment in staff development, health, safety and environmental initiatives, as well as digital systems and technology, preparing the business for its next phase of growth.
