What has happened to Ardmore Construction?
Ardmore Construction, one of London's larger privately owned building contractors, has entered administration. The business built a significant presence in residential, commercial and fit-out construction across London and the South East over several decades, with a reported turnover exceeding £400 million at its peak.
The administration follows a pattern seen across the UK construction sector, where contractors have faced fixed-price contracts agreed before inflation peaked, rising material and labour costs, extended project timelines and tightening client budgets.
Which projects are affected?
Ardmore had a number of live construction sites at the point of administration. The status of those projects will depend on the terms of each individual contract and the decisions made by the administrator. Clients with live contracts should seek legal advice immediately and review the insolvency and termination provisions in their contracts.
In many standard-form JCT and NEC contracts, insolvency of the contractor is a ground for termination, but the process for novating or completing works through a replacement contractor requires careful management to avoid additional cost and delay exposure.
What happens to subcontractors and suppliers owed money?
Subcontractors and suppliers with unpaid invoices will be treated as unsecured creditors in the administration. Recovery rates for unsecured trade creditors in construction insolvencies are typically low. Those owed money should stop work on any Ardmore-related sites pending instruction from the administrator and retain all documentation of work completed and invoices raised.
Where a subcontractor has a retention sum withheld by Ardmore, that amount forms part of the unsecured creditor pool unless held in a separately designated retention trust account. The absence of statutory protection for retentions in construction has long been identified as a systemic risk.
What are the rights of Ardmore employees?
Employees are preferential creditors for limited categories of arrears including up to eight weeks of unpaid wages and certain holiday pay under the Insolvency Act 1986. Employees whose positions are made redundant can claim statutory redundancy pay through the Redundancy Payments Service at gov.uk.
Why are construction firms failing in 2026?
The construction sector has seen an elevated rate of insolvencies since 2022. Key factors include fixed-price contracts entered into before material costs rose sharply, extended project timescales from planning delays and supply chain disruption, and a reduction in private development activity as interest rates remained elevated through 2024 and 2025.
For contractors working on residential schemes, slower sales rates for completed units created cash flow pressure on developers, which in turn delayed payments down the supply chain. The combination of thin margins and payment delays creates systemic fragility in businesses carrying large overheads.
What should clients do if Ardmore was building their project?
Clients should: review the insolvency provisions in their contract; secure the site and any materials on it; instruct solicitors to advise on contractor replacement and potential bond or insurance claims; notify their funder if the project is bank-financed; and register as a creditor with the administrator for any advance payments made.
What is the wider impact on the construction supply chain?
The failure of a contractor of Ardmore's scale has ripple effects across a wide network of subcontractors, labour agencies, plant hire companies and materials suppliers. Many of these are small and medium-sized enterprises that extended significant credit on the assumption of payment within standard industry terms. The Construction Leadership Council has consistently called for reform of retention practices and payment terms in the sector.
