Heidelberg Materials UK

Heidelberg Materials UK produces aggregates (crushed rock, sand and gravel), ready-mixed concrete, asphalt, cement and cement related materials and undertakes certain contracting services.  Heidelberg Materials UK is a part of the global Heidelberg Materials group of companies (formerly HeidelbergCement group), which has leading positions in aggregates, cement and concrete. Further information on our company structure can be found here.

The vast majority of Heidelberg Materials UK's suppliers (and supply chain) are UK based. As such, products and materials are largely sourced only from the UK.  Heidelberg Materials UK's supply chain also draws on certain supplies to the wider Heidelberg Materials group.  

As a result of any risks faced by supplies sourced from the UK, as well as in the context of the risks arising from other countries, Heidelberg Materials UK has in place various policies, procedures and processes to address modern slavery risks in its supply chain. These are described in this statement.

Policies and procedures in respect of modern slavery

Heidelberg Materials UK operates under a Heidelberg Materials group compliance framework which commits the companies to the eight core labour standards of the International Labour Organization (the "ILO"), the OECD Guidelines for Multinational Enterprises, the UN's Universal Declaration of Human Rights and the UN Guiding Principles on Business and Human Rights. These principles have also been incorporated into Heidelberg Materials’ Leadership Principles and Human Rights Position.

Heidelberg Materials UK follows a Code of Business Conduct which can be found here. This commits Heidelberg Materials UK to conducting business strictly in accordance with all applicable laws and regulations. Heidelberg Materials UK is committed to fair employment practices and to following all applicable labour and employment laws.

Heidelberg Materials UK's standard contractual terms of purchase require suppliers and relevant third parties to comply with a specific Supplier Code of Conduct, a copy of which can be found here. This Supplier Code of Conduct requires vendor compliance with international social accountability standard SA 8000 and principles of the ILO.

Key requirements from the Supplier Code of Conduct in respect of modern slavery are as follows:

  • Suppliers are prohibited from using child labour in any stage of manufacturing. Suppliers are required to operate in accordance with the ILO convention recommendation of minimum age for admission to employment.
  • Compensation and benefits must comply with fundamental principles relating to minimum wages, overtime hours and legally mandated benefits.
  • No form of forced or compulsory labour may be used and employees shall be free to leave employment on reasonable notice.
  • Suppliers are expected to adhere to the right of employees to freedom of association and recognition of employees’ rights to collective bargaining, in accordance with local law.
  • Workers must have safe and healthy working conditions that meet or exceed applicable standards for occupational health and safety. 
  • Suppliers must require their own direct suppliers to adhere to the principles of the Supplier Code of Conduct and exercise diligence in verifying that these principles are being adhered to in their supply chains.

Heidelberg Materials UK’s production sites and products are certified to BES 6001 standards in respect of Responsible Sourcing of Construction Products. Responsible Sourcing of Construction Products encompasses social, economic and environmental dimensions. It addresses aspects such as stakeholder engagement, labour practices and the management of supply chains.  A list of Heidelberg Materials UK’s accreditations can be found here2. Members of Heidelberg Materials UK have been awarded an 'Excellent' rating in respect of: Aggregates; Asphalt Mixes; Cement; Ready Mixed Concrete; and Ground Granulated Blastfurnace Slag product categories.  Other Responsible Sourcing accreditations have also been awarded. 

Heidelberg Materials UK's Sustainability Policy can be found here. It confirms our objective of striving for the fair treatment of everyone in our supply chain and confirms that we are committed to complying with certain standards (including BES 6001) in respect of the responsible sourcing of construction products. 

Assessing and managing risk

The Heidelberg Materials group has been running a risk assessment survey in respect of child labour and human rights violations since 2013. Heidelberg Materials UK last completed its own human rights risk assessment in 2021 and this risk assessment is updated on a regular basis. 

Heidelberg Materials UK’s suppliers are assessed against wide ranging criteria during tender / appraisal processes. This includes assessment against the Code of Conduct and the Supplier Code of Conduct. Specific diligence is required by the standard appraisal procedure in respect of modern slavery, health and safety and corporate social responsibility, including diligence in respect of working conditions, employee pay, employee age restrictions and independent employee grievance procedures.  The Master Data team at Heidelberg Materials UK’s Shared Service Centre carry out many wide-ranging background checks in conducting such diligence in order to make a risk assessment as to whether new suppliers meet such criteria and any alerts are flagged for further internal review and also recorded to monitor year by year trends. 

The procedures of Heidelberg Materials UK are regularly assessed against best practice.  Part of this assessment is a review of the extent to which modern slavery can be identified and eliminated from its business and supply chain. 

The Heidelberg Materials group has a global pre-qualification program for its suppliers and contractors to assess suppliers’ ability to fulfil Heidelberg Materials’ requirements with regard to sustainability and corporate social responsibility. Questions are asked and documentation requested in areas relevant to modern slavery including voluntary employment, child labour, freedom of association and human rights and welfare.  

Heidelberg Materials UK and the Heidelberg Materials group also have in place a compliance hotline (SpeakUp) for reporting any incidents of non-compliance with the Supplier Code of Conduct.  Since 2013, this has also included criteria for reporting violations (if any) of various human rights and core labour standards such as discrimination and child labour. It enables both internal and external whistle-blowers to provide information about possible human rights violations and infringements of labour standards, as well as in relation to infringements of other laws. Every report is investigated.  As in previous years, there were no instances of child labour or forced labour reported or alleged within Heidelberg Materials UK's business or supply chains in 2022.

Heidelberg Materials UK implemented specific anti-slavery training as a further enhancement to its protocols. Over one thousand five hundred employees in Heidelberg Materials UK have completed this training to date which includes new joiners during 2022.  This is in addition to general compliance training that Heidelberg Materials UK has in place.  Modern slavery awareness is also raised through an annual company-wide bulletin.

In 2022, a new platform, SAP Ariba Sourcing, featuring an integrated risk assessment module which will further enhance its supplier vetting process in relation to modern slavery, was introduced by the Heidelberg Materials group and is in the process of being rolled out worldwide.  Heidelberg Materials UK completed the set-up of the new portal during 2022 allowing for a simplified process in securing suppliers’ agreement to adhere to the Supplier Code of Conduct.  

In addition, Heidelberg Materials UK significantly exceeded its 2022 year-end target for 65% of supplier expenditure to comprise suppliers who have contractually agreed to comply with the Supplier Code of Conduct.  The final percentage of such supplier expenditure for 2022 was 90%.  Processes are in place to ensure the percentage remains above the new minimum target, which has been set at 80% for 2023.

This statement was approved by the board of directors of Heidelberg Materials Quarry Products Europe Limited on  6 June 2023.
