Our basis for
Reporting and Assurance

International Integrated Reporting Framework

We utilise the principles of the International IR Framework in the preparation of our Annual Report and Accounts. IR applies principles and concepts that are focused on bringing greater cohesion and efficiency to the reporting process, and adopting 'integrated thinking' as a way of breaking down internal silos and reducing duplication. It improves the quality of information available to providers of financial capital to enable a more efficient and productive allocation of capital.

UN Global Compact

We participate in the UN Global Compact (UNGC), a strategic policy initiative for businesses that are committed to aligning their operations and strategies with ten universally-accepted principles in the areas of human rights, labour, the environment and anti-corruption. Our values and Code of Ethics reflect the UNGC.
Read more on how we implement the UNGC principles.

Non-financial reporting

Reporting on non-financial performance across customers, people, community investment and environment can be found in the specific sections of our material issues section.

Socially responsible investment

We have been included in the FTSE4Good index for the past seven years, and have also commissioned our own external benchmarking based on the criteria used for the Dow Jones Sustainability Index. We participate annually in the Carbon Disclosure Project. See Benchmarking and awards.


Our environmental data is externally verified as part of the annual environmental audit by Ricardo Energy and Environment.
Our community data is reported in line with the London Benchmarking Group methodology and our use of the model is independently assured by Corporate Citizenship.
