Our Suppliers

Our business operations critically rely on our supply chain to deliver quality homes for our customers. 

Creating a responsible supply chain

We are partners with the Supply Chain Sustainability School to assist in the delivery of a consistent approach to sustainability and responsible sourcing. The School provides a learning and engagement platform to upskill people working within the built environment sector. Our partnership support enables free online learning materials, seminars, workshops and other services for our supply chain to help it improve environmental, social and economic sustainability awareness on issues including carbon reduction, waste reduction, resource use and human rights.

Ensuring ethical, safe and fair working conditions within our supply chain is very important, and we operate a robust approach to supplier selection and adherence to our policies. We are mindful of the risks of modern slavery in the construction industry and have training programmes in place, site inspections and whistleblowing provisions.

Respecting Human Rights across the value chain

As a housebuilder we operate solely within the UK, with most of our first-tier supply chain and subcontractors also being UK based. Nonetheless, the Group recognises that the construction sector has a particularly high exposure to modern slavery risk. In this context, we have established robust controls and procedures to reduce this exposure and to provide assurance that our employees and suppliers continue to work to the high standards we demand.

In 2025, we have continued our engagement with organisations which provide access to intelligence on modern slavery trends and good practice guidance. This includes the CCLA-led ’Find it, Fix it, Prevent it’ initiative, and the Gangmaster and Labour Abuse Authority (’GLAA’). Senior members of the Group’s Management team have attended engagement events with the CCLA to benefit from their expertise and understand stakeholder concerns for our sector. The regular bulletins from the GLAA are also shared with our teams to ensure than any relevant intelligence can be acted upon promptly.

These actions have helped us further build our comprehensive suite of controls. Controls include regular audits on supply chain and increasing awareness, led by our Group Internal Audit department. Awareness posters are also in place at all sites, encouraging the reporting of potential concerns via our whistleblowing provision. Routine inspections and worker interviews are carried out by the Group HS&E department, and tailored training is in place for employees in Commercial, Procurement and Construction functions. Site-based workers also receive an annual training session via The Persimmon Way App, which reached over 20,000 workers.

Responsible sourcing of timber

We are committed to responsible sourcing and look to use supply chain systems, which minimise the environmental impact associated with the production of key commodities such as timber. All buyers, surveyors, suppliers and subcontractors to Persimmon via Group deals are required to purchase Forest Stewardship Council (‘FSC’) or Programme for the Endorsement of Forest Certification (‘PEFC’) certified timber and timber-derived materials for use in all our operations.

If FSC or PEFC certified timber and timber-derived materials cannot be purchased, evidence must be provided that alternative materials are sourced from reputable and sustainable sources.

As a minimum, all buyers, surveyors, suppliers and subcontractors must ensure compliance with any applicable laws and regulation in relation to the sourcing of timber and timber-derived materials. The Group Procurement department actively tracks compliance with this policy.

Timber and timber-derived materials are a key feature of our annual Carbon Disclosure Project (‘CDP’) reporting, through the Forestry section of the questionnaire. We gain the information for our disclosure from a detailed annual questionnaire to our Group timber and timber product suppliers.
