A significant UK construction company has officially entered administration, according to a recent notice. The Hampshire-based firm, which specialises in infrastructure for housing and commercial developments, has been operational since 2011.
Company Background
Mackoy Limited, a groundworks contractor, was one of the largest of its kind in the South East of England. The family-owned business employs over 300 operatives across the South and has established a strong reputation in the region. Its work includes "all aspects of essential groundworks to service large-scale building projects in Hampshire, Dorset, Sussex, Surrey, Berkshire and beyond," as stated on its website.
The company has invested more than £10 million in new plant since its inception. However, its latest accounts for the year ending March 31, 2025, show a turnover of £23.3 million, resulting in a pre-tax loss of £616,000. This marks a significant decline from the previously reported profit of £866,000.
Reasons for Financial Difficulties
Mackoy attributed its financial troubles to interest rate rises, which caused delays in new housing projects, and increased costs affecting existing contracts. These challenges are not unique to Mackoy; several other construction firms have entered administration in recent months, citing costly materials and operational expenses.
Administration Details
Kelly Mitchell and Alyson Richards of Quantuma Advisory Limited were appointed as administrators on June 9, 2026, as per an official notice in the London Gazette. The company's registered address is Unit 10, Monks Brook Industrial Park, School Close, Chandlers Ford, Eastleigh, which also serves as its principal trading address.
Administrators have been contacted for comment. Mackoy joins a growing list of construction firms facing financial difficulties, including a century-old ceiling specialist that recently ceased trading and Northamptonshire-based Agetur, which entered administration after a sharp dip in trading.
