On 02 October 2023 we rebranded to Heidelberg Materials. As well as aligning with our parent company, our new name better reflects the company we are today.
We’re focused on driving down carbon emissions, increasing the use of recycled materials to grow the circular economy and leading our industry towards net zero with innovative projects such as carbon capture and storage.
Some of the new Heidelberg Materials signage and vehicle livery is already in place and we hope to have completed this within the next two years. Please note that our email and website details have also changed.
Coldstones Quarry, situated on Greenhow Hill at 1400 feet above sea level, is one of the highest quarries in Britain. Several small limestone quarries operated around Greenhow over the last two centuries and in the early 1900s the surrounding hills were dominated by stone quarries. Gradually these closed until Coldstones became the last working quarry in the area.Operated by Hanson, a member of the Heidelberg Cement Group, it provides aggregates and asphalt for major construction projects across the U.K.
The quarry currently covers an area of about 30 hectares. It is worked on 6 benches, 15-18m high, to a depth of 300m O.D (ordnance datum) at the base of the quarry.
Coldstones provides an average of 600,000 tons of aggregate each year, and supplies building materials into West and North Yorkshire.
Interesting fact: Coldstones Quarry has achieved both a 5 Star Environmental Award from the Quarry Products Association and the Harrogate Borough Council Special Award for Environmental Excellence, in recognition of educational work with local schools and its active support of the local heritage.
In 2005 Hanson UK set up the Greenhow Enhancement Fund to mitigate the impact of the extension of Coldstones Quarry in Greenhow on the surrounding landscape.

There is a public viewing platform at Coldstones Quarry called THE COLDSTONES CUT, this is an artist designed viewpoint commissioned by Nidderdale Visual Arts and designed by Andrew Sabin, it is opened to the public at all times and in 2011 was awarded the Bruntwood Award for Arts and Business and the Marsh Award for Excellence in Public Sculpture. In the MPA Biodiversity Awards in 2013, it won the Special Award.
Coldstones Cut has “Certificate of excellence” on Trip Advisor and gets over 20,000 visitors a year. From here you can see the quarrying operations, including the blasting, extraction and crushing of rock. You can also see the geological strata which make up the quarry and which provide the raw material for its products.
