Helix Construct files notice to appoint administrators after accounts flag cash and profit pressures

What happened

Helix Construct, a Newbury-based contractor that works on affordable housing, education, care and commercial projects across London and the south of England, has filed a notice to appoint administrators at the High Court. The move endangers more than 40 jobs and affects the business and its suppliers.

The firm's most recent accounts cover an 18-month period to June 2025. Key figures and disclosures in those accounts are:

• Turnover increased to £40m for the 18 months to June 2025, compared with £21m in the previous 12 months.
• The business recorded a £182,000 pre-tax loss versus a £542,000 profit in the prior period.
• Auditors raised concerns about accounting judgments on three long-term construction contracts with an aggregate value of £1.02m, specifically challenging the timing of profit recognition and the valuation applied to those jobs.

Directors defended their accounting treatment but disclosed they had strengthened financial reporting, project forecasting, contract reviews and oversight following the auditor's challenge.

Management explanation for the losses

Helix's directors attribute the downturn to several operational and market factors:

• Project start delays caused by planning requirements, client funding approvals and regulatory processes.
• Construction cost inflation and operational problems on a small number of contracts.
• Delayed mobilisation, which extended the period over which overheads must be recovered and increased working capital needs.

The accounts also note that the company had been investing in land-led development, expanding regional operations, creating joint ventures and growing the senior management team.

Ongoing uncertainty and post-period losses

The accounts, signed off in July, say losses continued after the period end. Management forecasts relied on successful project delivery, achieving forecast margins and maintaining funding. The directors stated these dependencies represented a material uncertainty that may cast significant doubt on the company's ability to continue as a going concern.

Strategic moves prior to trouble

In 2022, Helix diversified into house building through a unit called Helix Partnership Homes. That arm targeted small schemes of four to 30 homes as a way to build an in-house development pipeline in response to government calls for SME involvement in housebuilding.

Immediate implications

Filing a notice to appoint administrators signals severe financial distress and starts a formal insolvency process that can lead to administrator appointment, restructuring, sale, or liquidation. For employees, subcontractors and clients, the immediate consequences include job insecurity, potential payment delays or unpaid invoices, and uncertainty over ongoing projects.

What to watch next

• Whether administrators are appointed and, if so, what plan they propose for ongoing projects and creditor recoveries.

• Impact on subcontractors and suppliers tied to Helix projects in London and the south of England.
