We advised Thames Materials Ltd (Thames), a leading construction waste management company, on its sale to Holcim, a leading provider of sustainable building solutions.

The acquisition will reinforce Holcim UK’s position in the recycling and construction demolition materials (CDM) market in London and surrounding areas and is a key pillar of the company’s growth strategy.

Thames Materials was formed in 1995 and has grown into a leading waste recycling and aggregate supplier to utilities, infrastructure and construction projects throughout the London area.

It specialises in the removal, haulage and recycling of waste from construction sites across London and surrounding counties. In 2024 it received more than 400 Kt of material for processing, recovering 340 Kt for sale into the secondary aggregates market through the use of state-of-the-art processing and wash plant equipment. Where material has little recycling potential, the business redirects it into land restoration projects. With only 5% of material diverted to landfill, the acquisition further strengthens Holcim’s commitment to the UK’s circular economy.

We’re really looking forward to taking the business forward with Holcim UK and harnessing their expertise and networks. This move allows us to continue on our growth trajectory and expand both our capacity and offering. Holcim is a market leader in the UK and internationally with a clearly articulated vision for circularity and sustainability and we are excited to be a part of that.

I am very pleased to announce the acquisition of Thames Materials and feel that it’s really exciting for them to be joining Holcim. It strengthens our footprint in the London construction market and aligns to our ambition of making sustainable construction a reality as we work towards becoming the leading UK provider of sustainable solutions. We only have one planet. Now, more than ever, we must ensure we prolong the life of our natural resources and look to build new from old as much as possible.

Thames also has a great synergy with our existing recycling and construction demolition materials business in the East of London and the acquisition will allow us to develop our services and reach to support the move to a more circular economy - especially with the need for greater use of recycled or reused materials in projects within the capital. By 2030 we have set ourselves a target to process 6.5 million tonnes of CDM annually.

Lee Sleight, CEO, Holcim UK

This transaction marks a significant step in advancing the UK’s circular economy. The recycling of construction and demolition (C&D) waste and the use of secondary aggregate both play a crucial part in making our construction sector more sustainable. Thames and Holcim both have a strategically important role to play in this regard, This deal strengthens Holcim’s position in the London market and adds further scale to their existing CDM operations. We were delighted to work closely with Thames on this transaction and look forward to following their next chapter of growth.
