Heidelberg announced the acquisition move on the £220m turnover Mick George business last year to strengthen its circular materials offering while complementing its existing aggregates and ready-mixed concrete businesses.

Mick George operates four recycling facilities, eight waste transfer stations, 11 aggregates quarries and 10 ready-mixed concrete plants.

But the CMA raised concerns about competition in certain markets for building materials in East of England and the East Midlands.

Heidelberg has now gained agreement from the CMA for the deal to be rubber stamped after putting up its own proposals to offloads parts of the business in key areas to Essex-based Brice Aggregates and Peterborough-based P J Thory.

The divestments include five ready-mixed concrete businesses in Northampton, Market Harborough, Wellingborough, St Ives (Peterborough) and Ely.

The giant will also sell two of its quarries at Needingworth in Cambridgshire and Earls Barton in Northamptonshire, and offload Mick George’s Ringstead Grange Quarry in Kettering, and Watlington Quarry, near Peterborough.
