The move was confirmed in latest results for parent company Durkan Holdings Ltd following a period of the contracting operation being scaled down.

The company said: “Following more than 50 years operating in the contracting sector, Durkan has taken the strategic decision to withdraw from this activity.

“This decision reflects the increasing legislative and regulatory burden in the sector which has driven heightened risk and declining returns.”

The move leaves Durkan operating as a homes and regeneration business following the completion of its final contracting project in Greenwich.

Legacy fire remediation costs will be treated as exceptional items going forward with £18.6m set aside last year.

Gradually withdrawing from contracting saw group turnover drop to £146m for the year to 30 November 2025 from £192m last time.

Contracting was the largest revenue driver at the business last year with a turnover of £86.7m  compared to £28.7m at the Regen business and £30m at Homes.
