Groundworks infrastructure and civil engineering specialist Mackoy Limited, trading as Mackoy Groundworks, has been bought out of administration by new company Geocore Civils Limited.
All 20 jobs in the old company have been protected under TUPE regulations and the pre-pack sale secures the future of the business, which is based in Chandler’s Ford, Hampshire.
Established in 2011, Mackoy provided groundwork, infrastructure, and civil engineering services to the UK’s leading house builders. Mackoy had established itself as one of the largest groundwork specialists operating in the South of England, providing foundations for new homes, roads and sewer systems. Turnover of the company was reported as £23.3m in 2025.
Recently, the business had experienced several challenges, including increases in the cost of materials and labour, which affected previously agreed contract pricing. This, combined with changes in buyer behaviour, had a negative impact on cashflow and profitability.
Following an accelerated sales and marketing campaign, Kelly Mitchell and Alyson Richards of Quantuma we appointed joint administrators and have secured the pre-pack sale of the Company.

Geocore Civils Limited was first registered on 12 May 2026, with directors Ben Bousfield and Mike Mayock, the former managing director and chairman of Mackoy respectively.
Kelly Mitchell, joint administrator and managing director at Quantuma, commented: “I am incredibly pleased to have achieved such a positive outcome for this highly regarded business, ensuring that all employees’ jobs have been saved.
“We are happy to have secured the long-term viability of the business, allowing it to continue its journey. We wish the team every success in their next chapter.”
