The materials giant confirmed it has ceased production of GRC after the division made a trading loss of £3m last year.

Ibstock said: “The GRC business recognised a trading loss of around £3 million in 2024, reflecting acute pressure on margins in the current market environment, as well as losses from recent subcontractor failures. 

“In light of its performance and near-term prospects, during the final quarter of the 2024 year, the Group took the decision to cease production of GRC after discharging all existing commercial commitments, which is expected to conclude during the first half of 2025.”

The move resulted in a £5m one-off charge in the latest results for the year to December 31 2024 which showed pre-tax profit down to £21m from £30m last time on revenue of £366m from £406m.

The GRC facility was based in the West Midlands where it designed facades for mid and high-rise buildings in the residential and commercial sectors.
