What happened

Subcontractors are set to lose out on £5.1m following the administration of Ardmore Construction Group, according to a report from administrators BTG published on Companies House this week and reported by Construction News and Construction Enquirer.

The £344m-turnover group went into administration in June, several months after its construction arm, Ardmore Construction Ltd, had itself collapsed in August 2025. The group filing followed a judgment that found it liable to pay £14.9m to Crest Nicholson over an adjudication dispute. BTG's report puts total unsecured creditor claims at £10.6m, made up of £5.1m owed to subcontractors and £1.8m owed to 132 former employees, with no cash expected to be recovered for either group. The report also flags a further 23 potential claims tied to work carried out by the collapsed construction arm, which BTG estimates could total up to £300m if they proceed.

Why it matters

This is a reminder that a contractor collapse rarely ends cleanly on the day administrators are appointed. It can take months, sometimes years, for the full scale of exposure to emerge, as claims and adjudications work their way through the process. Ardmore Construction Ltd went under a year ago, and its parent company has only now been forced into administration by a single adjudication judgment. The prospect of another £300m in potential claims shows how much liability can sit unresolved on a construction group's balance sheet long after the trading business has stopped.

For the wider market, it's another data point in a difficult year for contractor insolvencies, which have now risen for two consecutive months according to the Insolvency Service's most recent figures, with construction remaining the worst-hit sector in the UK economy.

What it means for your career

If you're a commercial manager, QS or contracts director working with subcontractors on live schemes, this is a case study worth keeping in your back pocket for supply chain risk conversations. A defects or adjudication liability can resurface at parent-company level long after the operating business has gone quiet, so due diligence on a contractor's group structure, not just the entity you're contracting with, matters more than ever.

For anyone currently weighing a move to a mid-size contractor, ask about the group's claims history and how adjudication risk is tracked, not just the order book. And if you sit on the subcontractor side, this is a strong argument for tighter retention terms and credit insurance on any tier one or tier two relationship, particularly with firms that have a history of disputed final accounts. Commercial and risk roles at firms that can demonstrate robust supply chain protection are increasingly valued, this is exactly the kind of scenario boards are now hiring commercial directors to prevent.
