Ardmore Construction Group enters administration

Ardmore Group has confirmed that several of its construction operating companies have entered administration, marking one of the most significant contractor failures to emerge from the post-Grenfell building safety regime.

The administration affects Ardmore Construction Group, Ardmore Construction, Ardmore Construction Limited, Ardmore Major Projects, Ardmore Regeneration, Ardmore Fit-out, Ardmore Hotels & Commercial, and Ardmore Landmark. The wider Ardmore business has said it has not entered administration and has applied for a moratorium while it continues to assess its legal and commercial position.

Pressure on the business is linked to legacy fire-safety liabilities arising from Admiralty Quarter in Portsmouth, a residential development completed between 2007 and 2009. The scheme later became subject to extensive defect and fire-safety claims, with liabilities increasing sharply after a Building Liability Order judgment under the Building Safety Act 2022.

Ardmore is preparing an appeal, with permission granted and the Court of Appeal agreeing to expedite the case. The company argues that the judgment raises wider legal questions around the circumstances in which Building Liability Orders can be made and the extent to which liabilities can move through associated company structures.

Several live London sites have been closed, creating immediate uncertainty for clients, subcontractors, suppliers, and staff. More than 100 employees are reported to be affected, while supply-chain companies tied to Ardmore’s operating businesses will now have to assess outstanding payments, incomplete works, and the status of active packages.

The failure comes against a difficult financial backdrop. Ardmore Construction Group reported a pre-tax loss of more than £42m on turnover of around £346m in its most recent accounts, despite maintaining a substantial order book. The business had remained active on major London projects, including complex high-rise, hotel, and mixed-use schemes, but historic liabilities placed further pressure on a balance sheet already exposed to inflation, programme risk, and dispute costs.

Building safety liabilities have moved from a compliance concern into a major financial exposure for contractors, developers, landlords, and professional teams. The Building Safety Act has extended limitation periods and created new routes for recovering remediation costs, including through associated companies in certain circumstances. Historic residential work can now generate current liabilities long after completion, particularly where cladding, compartmentation, fire-stopping, or design responsibility remain contested.

That shift is already shaping procurement and risk allocation. Contractors taking on residential work are facing greater scrutiny of fire strategy, product substitution, workmanship records, gateways, and long-term accountability, while clients are examining balance sheets more closely before appointing delivery partners. The pressure is also visible in remediation procurement, including Portsmouth’s £120m framework for tower block safety works, where councils and housing providers are moving large programmes into the market.

The consequences extend beyond main contractors. Specialist façade contractors, fire engineers, insurers, funders, certifiers, and leaseholder-facing clients are working in a market where historic records and contractual responsibility can define commercial survival. Disputes over old projects are no longer remote balance-sheet footnotes; they can affect trading, bonding, insurance, and access to future work.

The appeal process may clarify how far Building Liability Orders can reach, but the administration has already sharpened the industry’s view of historic building safety exposure. For construction companies with legacy residential portfolios, the dividing line between completed work and live risk is now far thinner than it once appeared.
