Persimmon Homes has entered into a partnership with Ecofill, a UK-based sustainable construction technology company, to support a more efficient and responsible way of managing surplus soils across its residential developments.

The partnership follows a rigorous trial phase, during which Ecofill’s technology was tested and validated on live housing sites, demonstrating clear evidence of impact and enabling Persimmon to embed this solution more widely into its construction delivery.

Ecofill’s technology enables soils and clays already present on site,  materials that would traditionally be sent to landfill,  to be processed and reused as high-performance aggregate replacement products. This significantly reduces the need for imported aggregates, cuts lorry movements, lowers carbon emissions, and improves safety both on site and on local roads, while also helping to minimise disruption to surrounding communities.

Using Ecofill’s specialist on-site machinery and carefully designed, low-carbon binder mixes, Ecofill converts surplus or soils into certified materials suitable for a wide range of construction uses, including adoptable roads, retaining walls, piling mats, embankments and trench backfills. All Ecofill materials are fully tested and independently validated to ensure compliance with all relevant national & European construction standards.

This provides Persimmon with a repeatable, scalable model for managing surplus soils, supporting consistency and best practice across all residential developments.

For Persimmon, the partnership reflects a disciplined approach to innovation, trialling new methods properly, validating performance on live developments, and integrating solutions that deliver measurable benefits without compromising quality or safety.

Dean Wigley, Group Engineering Director at Persimmon Homes, said:

“At Persimmon, we’re committed to building high-quality homes responsibly. We take a rigorous approach to innovation, ensuring solutions are properly tested and proven before they are integrated into how we build and deliver homes, at scale.

Working with Ecofill allows us to manage surplus soils more effectively, reduce waste and improve sustainability outcomes on our developments, while maintaining the standards our customers and communities expect.”

Trevor Gaughan, Founder and Chief Executive Officer of Ecofill, added:

“This partnership with Persimmon demonstrates what’s possible when innovation is validated through real delivery and then adopted as part of a wider construction approach.

By treating surplus soils as a resource rather than waste, we can significantly reduce landfill, cut carbon and improve safety both on site and on local roads. Collaborations like this are critical to decarbonising construction and delivering more sustainable places to live.”

The partnership will be supported by a joint programme of communications, including a partnership launch video and project-based case study examples, highlighting how the approach is being applied in practice on residential developments.

Together, Persimmon and Ecofill are demonstrating how proven innovation can be integrated into mainstream residential construction to deliver long-term environmental and operational benefits.
