IN Brief:
- Mackoy has filed a notice of intention to appoint an administrator.
- The Hampshire contractor reported £23.3m turnover and a £616,000 pre-tax loss in its latest accounts.
- The filing reflects continuing pressure on housing-linked groundworks and civil engineering specialists.
Mackoy has filed a notice of intention to appoint an administrator, placing one of the South of England’s larger housing-focused groundworks specialists under formal financial pressure.
The Hampshire-based contractor works across groundworks, infrastructure, civil engineering, earthworks, foundations, roads, sewers, drainage, and associated services for residential and commercial development schemes. Its contracts have ranged from £250,000 to more than £10m, with work across Hampshire, Dorset, Berkshire, Sussex, and Surrey.
Latest accounts for the year to 31 March 2025 show turnover of £23.3m and a pre-tax loss of £616,000. That compares with a pre-tax profit of £866,000 in the previous year. Directors warned in the accounts that interest rate rises had delayed new housing work, while existing contracts were affected by rising prices.
Mackoy was founded in 2011 and is based at Chandler’s Ford, near Southampton. The family-owned groundworks and civil engineering business has grown across the South, working with more than 300 operatives and investing more than £10m in new plant since it was established.
A notice of intention to appoint an administrator gives a company temporary protection from creditor action while restructuring or insolvency options are considered. It does not, on its own, mean that an administrator has been appointed.
The filing comes during a difficult period for specialist contractors exposed to housebuilding. Groundworks businesses sit early in the construction programme, so delayed site starts, slower plot release, and client caution can reduce workload quickly. These companies also carry heavy exposure to plant, fuel, aggregates, muckaway, labour, drainage products, and subcontracted packages, all of which have been affected by inflation volatility.
Groundworks packages are often priced months before site conditions, material costs, labour availability, and client programmes settle. If a scheme slows or costs move materially, the contractor is left managing fixed obligations against a shifting commercial base. Delayed starts also leave overhead and plant costs running while revenue recognition is pushed back.
Housing-linked civils contractors have had to navigate weaker private housing demand, planning delays, nutrient neutrality issues in some regions, higher funding costs, and developers taking a more cautious approach to land and site opening. The result is less predictable sequencing of work, which can be more damaging than a simple reduction in contract volume for businesses built around gangs, plant, and regional delivery teams.
Mackoy’s position will be watched by clients and suppliers across the southern housing market because groundworks capacity is not easily replaced at short notice. Disruption to a major groundworks contractor can affect roads, drainage, foundations, utilities corridors, and early-stage infrastructure across live or planned developments.
The case adds to wider evidence that the construction supply chain remains financially stretched despite selective recovery in some areas. Housing infrastructure specialists will depend on developers converting consented sites into live, funded, and properly sequenced work at a pace the supply chain can support.
