Durkan Quits UK Contracting After 50 Years as an £18.6m Building Safety Charge Wipes Out a £6.2m Operating Profit

If this were my business, I would price one number before I priced another tender. I would ask what every building I finished in the last twenty years could still cost me. Durkan has now put that answer on the record.

Durkan Holdings Limited has filed accounts for the year to 30 November 2025. Construction Enquirer reported them on 27 August 2026. Operating profit rose to £6.2m. An exceptional charge of £18.6m then landed. It covers legacy fire remediation claims under the Building Safety Act. The result was a net loss of £11.2m. On the same day the group confirmed it is leaving contracting altogether.

A solvent exit, and that is the point

Durkan is not short of money. Net assets stood at £33.9m at 30 November 2025. The cash balance was £36.5m. No administrator was appointed and no creditor forced the decision.

The company said the withdrawal follows more than 50 years in contracting and reflects an increasing legislative and regulatory burden. It named the consequence directly: "heightened risk and declining returns."

Contracting was the largest revenue line in the group last year at £86.7m. The regeneration arm turned over £28.7m and the homes business £30m. Group turnover had already fallen to about £146m from £192m as the contracting operation was scaled back. What is left is a homes and regeneration business, after a final contracting job in Greenwich.

Group chief executive Ronan Murphy said the costs relate to projects delivered years ago. Some go back decades. He tied them to the longer defects period under the Building Safety Act. He also cited delay and uncertainty in how the regime is applied.

That is the mechanic worth understanding. An income statement covers twelve months. The liability behind it now reaches back decades.

The Ardmore file shows where the money actually lands

A second London builder has just published the other version of the same story. Ardmore Construction Group entered administration on 11 June 2026 owing creditors £29m. The move followed a £14.99m adjudication award to Crest Nicholson. That claim concerned alleged fire safety defects at the 569-home Admiralty Quarter scheme in Portsmouth.

Administrators from BTG reported to creditors in August. Construction Enquirer set out the figures on 21 August 2026. Subcontractors are owed £5.1m. Other trade and expense creditors are owed £3.7m. HMRC is owed just over £5m. The creditor schedule lists 226 claims.

The contingent number is the large one. The company faces 23 potential developer claims. They are linked to work by sister company Ardmore Construction Limited, which failed in August 2025. No judgments have been made. Administrators put total exposure at anywhere between nil and £300m.

Assets of £23.1m sat in debtors, retentions and work in progress. Specialist insolvency quantity surveyor Kinetica estimates recoveries of between £546,500 and £1.57m. Unsecured creditors, subcontractors included, are currently expected to receive nothing.

Set the two figures side by side. Trade exposure of £5.1m against a defect tail the administrators size at up to £300m. The supply chain had already pulled its credit. The liability had not moved anywhere.

The remediation queue nobody wants to price

Government figures published on 27 August 2026 show more than 2,000 identified unsafe cladding blocks still waiting for work to start. Some 46 per cent of identified buildings have yet to begin remediation.

That is a large volume of work with a small pool of willing bidders. Insolvency Service data for the twelve months to June 2026 records 3,805 construction company insolvencies in England and Wales. That is the highest count of any industry. The rolling total sits about 5 per cent below the previous year. It is roughly 18 per cent above the 2019 figure of 3,221.

Two exit routes are now running in parallel. One is administration. The other is a board deciding the return no longer covers the tail. That board walks out with the balance sheet intact.

Why European sponsors should read this closely

This is a pricing signal rather than a British curiosity. Any jurisdiction that lengthens the period during which a finished building can be reopened creates the same effect. Contractors carry an open-ended provision against work already invoiced. Insurers and surety providers reprice. Capacity leaves the residential and higher-risk segments first.

For clients across Europe the practical consequence arrives at the tender box. Fewer firms will bid consented residential schemes. Bonding capacity, indemnity cover and the strength of the signing entity will matter more than headline price. Many public sponsors treat a performance bond as clean risk transfer. They should test what it now costs and what it excludes.

Developers and funders should assume they will carry more completion risk themselves. Well-capitalised clients have already started restructuring delivery around contractor failure rather than waiting for the market to fix it. The question for any board with a live residential programme is simple. If the builder walks away by choice rather than by insolvency, who finishes the building, and at what price.
