Assurance statement

Independent Assurance Statement to the management of Land Securities Group PLC

We have performed a limited assurance engagement on selected performance data and statements presented in the Land Securities Group PLC (the Group) 2016 Sustainability Report (the Report).

Respective responsibilities

The Group’s management are responsible for the collection and presentation of the information within the Report. Management are also responsible for the design, implementation and maintenance of internal controls relevant to the preparation of the Report, so that it is free from material misstatement, whether due to fraud or error.

Our responsibility, in accordance with management’s instructions, is to carry out a ‘limited level’ assurance engagement on selected data and performance claims in the Report (“the subject matter information”). We do not accept or assume any responsibility for any other purpose or to any other person or organisation. Any reliance any such third party may place on the Report is entirely at its own risk.

What we did to form our conclusions 

Our assurance engagement has been planned and performed in accordance with ISAE3000 (Revised) and to meet the requirements of a Type 2 assurance engagement as defined by AA1000AS (2008).  The criteria we have used to evaluate the Report (“the Criteria”) include the AA1000AS (2008) assurance principles of Inclusivity, Materiality and Responsiveness; and, for selected data, Land Securities’ own criteria as set out in the Report.

The procedures we performed were based on our professional judgement and included the steps outlined below:

  1. Interviewed a selection of the Group’s management and reviewed company-level documents to understand the progress made in the area of sustainability during the reporting period and test the coverage of topics within the Report.

  2. Conducted site visits to three development sites (Nova, Westgate and 1 New Street Square) to understand how the sustainability agenda is being managed at site-level.

  3. Reviewed the Group’s approach to stakeholder engagement through interviews with employees with responsibility for managing engagement activities and reviewed selected associated documentation.

  4. Reviewed the Group’s process for determining material issues to be included within the Report.

  5. Reviewed the coverage of key issues within the Report against the key issues raised in external media reports and the sustainability reports of the Group’s peers, as well as the topics discussed in our management interviews, site visits and by the Sustainability Committee and other internal working groups.

  6. Interviewed staff responsible for data reporting and carried out the following activities to review selected sustainability data:

i. Reviewed the guidance on data reporting, key processes and quality assurance performed.

ii. Selected a sample of data points from across the business and sought documentary evidence to support the data.

iii. Conducted a walk-through of data reported from a sample of sites to test consolidation. 

iv. Reviewed any explanations provided for significant variances. 

v. Reviewed the Report for the appropriate presentation of the data including limitations and assumptions.

Our review of data processes was limited to the following selected data sets:

Topic Selected Data
KPIs linked to executive remuneration
  • People trained and into jobs through Community Employment Programmes
  • Mandatory health and safety training (M1 & M2) completed within 6 months of joining
KPIs under EPRA Reporting
  • Direct GHG emissions (MtCO2e)
  • Indirect GHG emissions (MtCO2e)
  • GHG intensity from building energy (tCO2e/m2/ year)

The limitations of our review

Our evidence gathering procedures were designed to obtain a ‘limited level’ of assurance (as set out in ISAE3000 Revised) on which to base our conclusions. The extent of evidence gathering procedures performed is less than that of a reasonable assurance engagement (such as a financial audit) and therefore a lower level of assurance is provided. 

Completion of our testing activities has involved placing reliance on the Group’s controls for managing and reporting sustainability information, with the degree of reliance informed by the results of our review of the effectiveness of these controls. We have not sought to review systems and controls at the Group beyond those used for selected sustainability data (as presented in the table above).We have only sought evidence to support the 2015/2016 performance data.  We do not provide conclusions on any other data from prior years.

Our conclusions

Based on the scope of our review our conclusions are outlined below:


Has the Group been engaging with stakeholders across the business to develop its response to sustainability issues?

  • We are not aware of any key stakeholder groups that have been excluded from dialogue.
  • We are not aware of any matters that would lead us to conclude that the Group has not applied the inclusivity principle in developing its response to sustainability issues.


Has the Group provided a balanced representation of key topics concerning its sustainability performance?

  • We are not aware of any key topics concerning the sustainability performance of the Group which have been excluded from the Report.
  • Nothing has come to our attention that causes us to believe that the Group’s management has not applied its processes for determining material issues to be included in the Report


Has the Group responded to stakeholder concerns?

  • We are not aware of any matters that would lead us to conclude that Land Securities has not applied the responsiveness principle in considering the matters to be reported.

Completeness and accuracy of performance information

  • We are not aware of any material reporting units that have been omitted from the stated scope of the Group-level sustainability data.
  • Nothing has come to our attention that causes us to believe that the data relating to the above topics has not been collated properly from company-level systems.
  • We are not aware of any errors that would materially affect the data as presented in the Report.

How plausible are the statements and claims within the Report?

  • We have reviewed information or explanation on selected statements regarding the Group’s sustainability activities presented in the Report and we are not aware of any misstatements in the assertions made.

Observations and areas for improvement 

Our observations and areas for improvement will be raised in a report to the Group’s management. Selected observations are provided below. These observations do not affect our conclusions on the Report set out above.

  • Land Securities provides a detailed description of the materiality review that was undertaken this year to identify and prioritise the most critical sustainability issues for its business and wider stakeholders. This has resulted in a new sustainability strategy covering three focus areas: i) Creating jobs and opportunities; ii) Efficient use of natural resources; and iii) Sustainable design and innovation. The new strategy is simpler and more clearly articulates why sustainability is critical in running a successful property company. As the wider business context and stakeholder expectations change over time, Land Securities will need to periodically revisit this materiality review to ensure its sustainability strategy remains relevant for its business and wider stakeholders.
  • The Report describes the plan to conduct a review into responsible supply chain management and to develop a new management policy on this topic next year. As part of this review, Land Securities will need to identify the most significant sustainability risks within its supply chain and consider how it can best manage and mitigate these risks. Current activities to respond to the forthcoming requirements under the UK Modern Slavery Act could be included within this review. Where possible, we encourage Land Securities to report on specific risks within its supply chain and steps being taken to address them in next year’s Report.
  • Land Securities has reported two commitments this year in relation to: i) Maximising the biodiversity potential of all its development and operational sites; and ii) Ensuring its buildings are designed and managed to maximise wellbeing and productivity. Currently, these commitments are set out as broad aims and the Report describes current initiatives with the Wildlife Trusts and the World Green Building Council to deliver against them. In future years, Land Securities could consider clearly defining the outcomes to be achieved from these commitments and measure progress towards them with meaningful metrics.
  • Land Securities has well-structured processes for gathering, analysing and reporting energy consumption data across its London and Retail portfolios, which enables it to report Scope 1 and 2 greenhouse gas (GHG) emissions for its own operations and common areas in its properties. The report also includes Scope 3 GHG emissions associated with downstream leased assets and we encourage Land Securities to build on this good practice by incorporating other significant sources within its Scope 3 emissions from next year.

Our independence

We have implemented measures to comply with the applicable independence and professional competence rules as articulated by the IFAC Code of Ethics for Professional Accountants and ISQC1 . Ernst & Young’s independence policies apply to the firm, partners and professional staff. These policies prohibit any financial interests in our clients that would or might be seen to impair independence. Each year, partners and staff are required to confirm their compliance with the firm’s policies. 

We confirm annually to the Group whether there have been any events including the provision of prohibited services that could impair our independence or objectivity. There were no such events or services in 2015/16.  Our assurance team has been drawn from our global Climate Change and Sustainability Services Practice, which undertakes engagements similar to this with a number of significant UK and international businesses.
