Slavery and Human Trafficking Statement 2021

Our Modern Slavery Statement

Download PDF

This statement is made pursuant to section 54 of the UK Modern Slavery Act 2015 (‘the Act’) and covers the activities of Great Portland Estates plc (‘GPE’) and all the Group’s subsidiaries including Pontsarn Investments Limited (‘PI’). The Company supports Article 4 and more generally, the principles of the UN Universal Declaration of Human Rights and core conventions of the International Labour Organisation.

Our business

GPE is a property and development company owning, managing and developing commercial and residential real estate solely in central London through its joint ventures and subsidiaries including PI and those referenced on page 5. Whilst our statement applies to all subsidiaries listed, only GPE and PI have a turnover high enough to qualify for the Act.

In March 2021, the Group owned £2.5 billion of property and directly employed 116 employees.

All our direct employees are paid in excess of the London Living Wage and are based either at the Group’s head office or at buildings within our Investment portfolio.

Our business model requires us to work with diverse service partners to develop and operate our portfolio. Our supply chains are complex with over 1,600 service partners: these include direct service partners such as advisors, consultants and maintenance contractors and indirect service partners who may be subcontracted to Principal Contractors, or supply the materials used to construct or refurbish our buildings.

Our policies

We have a number of policies in place that protect our employees and those working on our behalf in our supply chain. In addition to policies which consider working hours, payroll and the right to work, we have the following policies in place:

  • Equal Opportunities, Harassment and Bullying Policy
  • Ethics Policy
  • Whistleblowing Policy
  • Sustainability Policy
  • Health and Safety Policy

These policies, in addition to our Slavery and Human Trafficking Statement, are communicated to all employees through our new employee induction process and when there is a material policy change, and they are accessible to all employees on our Intranet. Compliance with these policies is monitored by the Health & Safety, Human Resources, Company Secretarial and Sustainability teams.

Our supply chain

We recognise the importance of working with our service partners and our responsibility for seeking to ensure, through due diligence and risk management activities, that there is no slavery, forced labour or human trafficking within any part of our business or in our supply chains.

We set out and communicate our expectations with our supply chain in a number of ways:

  • our Service Partner Code of Conduct sets out the standards that we require of our service partners and specifically addresses involuntary, forced, human trafficked or slave labour including indentured, bonded and child labour;
  • under our Sustainability Policy, we expect our service partners to review their own activities and their supply chains to ensure that products and services used are from responsible service partners;
  • our Sustainable Development Brief for all developments and major refurbishments sets out our requirements for the responsible sourcing of materials, in particular, the usage of Forest Stewardship Council certification with its inclusion of aspects in connection with labour human rights for communities and forest workers; and
  • our Community Strategy commits to working with our contractors to eradicate modern slavery and addresses measures such as training, awareness and payment of the London Living Wage and encourages membership of the Living Wage Foundation.


  • when engaging any new contractor, we complete a competency check to ensure the contractor has the required health and safety provisions and controls in place for their workforce;
  • we support the objectives of the Gangmasters and Labour Abuse Authority’s Construction Protocol, which aims to eradicate slavery and labour exploitation in the building industry;
  • service partners are encouraged to engage with BES 6001, the Framework Standard for Responsible Sourcing, and BES 6002, the BRE Ethical Labour Sourcing Standard, which promote the responsible sourcing of both labour and materials;
  • all construction and refurbishment works from minor projects to our largest developments must be registered under the Considerate Contractors Scheme, which measures our contractors and construction sites against health and safety and social criteria;
  • slavery, forced labour and human trafficking is a standing agenda item at all our major project principals meetings to heighten awareness of the risk of slavery and human trafficking within ongoing development projects. We also meet regularly with our main contractors to share information on industry best practice about health and safety and responsible sourcing.

Wherever possible, we encourage our service partners to raise any concern with their usual point of contact at the Company. Alternatively, we have a formal whistleblowing policy, which can be found here, and provide a confidential whistleblowing hotline, operated by an independent third party, through which contractors and their workers can raise concerns on an anonymous basis.

Our risk assessment

Through our modern slavery and trafficking risk assessment, which is subject to ongoing review, we have concluded that, based on our own policies and procedures, the risks of slavery or human trafficking in the recruitment and engagement of our direct employees in our business is low.

Our risk assessment identified that our highest risks remained within our construction and refurbishment activities, both on-site labour and within the supply chains involved with the procurement of materials for our projects. Supply chains associated with this work can often include several tiers, making transparency more challenging.

Within our investment portfolio, we identified that our highest risk service partners were connected with cleaning and waste management processes due to the nature of the work, the high turnover of personnel involved and the use of agency workers in those industries.

Supply chain monitoring and due diligence for the year ended 31 March 2021:

  • we updated our Service Partner Code of Conduct which sets out the standards we require of our service partners to help ensure they operate ethically and responsibly. Updates included strengthened minimum labour standards and the requirement for contractors to register with the Considerate Constructors Scheme (CCS), where appropriate for the scheme;
  • we continued to use Safety Systems in Procurement (SSIP) prequalification schemes to ensure all our main contractors have been appropriately vetted for health and safety and other ethical matters and have incorporated reference to our Service Partner Code and Sustainability Policy in all new development and facilities management contracts;
  • we continued to undertake independent Labour Practice Audits at all our active construction sites over £5 million (construction costs), raising awareness of our commitment to the eradication of slavery and human trafficking from our supply chain. We recommenced the audit programme in 2021 following a period of postponement in 2020 due to the COVID-19 pandemic;
  • our confidential whistleblowing hotline, Safecall, continued to be promoted at our active construction sites;
  • we sponsored poster campaigns at all of our construction sites to provide information on modern slavery and human rights;
  • monitoring was undertaken to ensure that 100% of our contractors remained accredited by an appropriate SSIP;
  • our service partners continued to pay the London Living Wage for all their employees working in our buildings and we are working with our construction contractors at our developments to support the continued roll-out of the London Living Wage through their supply chains.

Training and awareness

Ongoing training forms a key part of our commitment to eradicate modern slavery. During the year ended 31 March 2021, we partnered with Unseen, a modern slavery charity and provider of the Modern Slavery Helpline, to deliver bespoke training to the GPE team. Following the training, 71% of our people felt more confident in their ability to spot the signs of modern slavery and how to respond should they identify any concerns. We continued to provide initial training on our policies and the risks of modern slavery within our employee induction programme for all new joiners.

We provided financial support to Hestia’s Phoenix Project, through our COVID-19 Community Fund, in recognition of how the pandemic exacerbated existing vulnerabilities of modern slavery victims. Our donation enabled Hestia to support 56 adults and over 60 dependent children in London.

Ongoing effectiveness

We have no reason to believe that slavery, forced labour or human trafficking has occurred within our supply chains based on the policies, actions and measures taken above.

We had no reports to our confidential helpline involving modern slavery concerns.

During the year, our Labour Practice Audit programme identified opportunities to strengthen controls in certain areas as contractor processes were adapted as a consequence of COVID-19.  In one particular instance, this included a contractor’s introduction of virtual documentation checks for its workers.  While no evidence of modern slavery was found, improvements were agreed with the Principal Contractor to strengthen control measures without breaching COVID protocols.

At the start of the COVID-19 pandemic, construction was temporarily paused at our active sites until additional arrangements could be implemented to protect worker health and safety in line with government guidance. Our Project Managers undertook regular site visits to view the measures in place, which also supported ethical labour standards give the potentially higher risk of modern slavery during the pandemic.

We continue to evaluate our processes and our supply chains to further best practice in the prevention of slavery, forced labour and human trafficking.

During the year ending 31 March 2022 we will:

  • continue our auditing programme for our construction projects and cleaning contractors;
  • enhance our labour practice audit programme to ensure that both the demolition and construction phases are audited due to the different risk profile of these sub-contractors.
  • deliver enhanced awareness training for employees with procurement responsibilities. We will also extend our awareness programme to our main contractors and provide training where appropriate;
  • strengthen key performance indicators to support improved management of risks connected with modern slavery;
  • review main contractor accreditation standards to ensure that they reflect the risk profile of the contractor concerned;
  • undertake an exercise to improve the transparency of our supply chains relating to the materials procured for our development projects. This detailed sourcing information will help to minimise both ethical and environmental risks; and
  • review and update our Sustainable Development Brief and as part of this process improve transparency from service partners regarding the procurement processes for the materials purchased on our behalf and used on our projects.
