Make reported information easier to substantiate
ESG reports often depend on information held across finance, operations, HR, procurement and property teams. Land Sterling helps organisations establish responsibilities and controls so that reported figures can be traced to their sources and reviewed consistently.
Our assurance-readiness work identifies weaknesses in evidence, definitions and approval processes before they become recurring reporting problems. It prepares the organisation to respond more effectively to internal review or an external assurance provider; it does not itself constitute an independent assurance opinion.
Our ESG data and control services
We begin with the indicators and disclosures the organisation needs to support, then work backwards to the data owners, source documents, calculations and approvals required.
Evidence requests and ownership
Create a data request list linked to the reporting scope and assign an accountable owner to each requirement. The register records the relevant period, entity, unit and source document so that teams understand what to provide and reviewers know what to expect.


KPI definitions and collection rules
Document indicator definitions, calculation boundaries and collection frequency. Clear instructions reduce inconsistent interpretation between business units, sites or reporting periods and help distinguish a genuine performance change from a change in the method used to collect data.
Completeness and quality reviews
Check whether expected evidence has been received and whether it covers the intended scope. Quality reviews flag unusual values, inconsistent units, duplicated records or unsupported figures. Issues are assigned for investigation rather than silently corrected or removed.


Estimates and exception management
Where primary information is unavailable, document the estimation basis, assumptions and approval. Maintain an exception log with responsible owners and remediation actions. This gives management visibility of uncertainty and prevents estimates from being presented as directly measured results.
Review and approval workflows
Separate preparation from review through an appropriate maker-checker process. Record KPI approval, version changes and reporting decisions so that the final output has a traceable review history and the team can explain how a figure reached publication.


Assurance preparation and support
Organise the evidence pack around the selected scope and review requirements. We help teams identify likely information gaps and coordinate responses to requests from the appointed assurance provider. The provider’s independent judgement and engagement requirements remain separate from our preparation work.
A repeatable evidence pack
Deliverables can include an evidence register, data-quality report, approved KPI register, exception and remediation log, and a structured reporting pack. Digital workflows can support collection and version control without replacing accountable review.

Link reporting controls to the people providing the data
Land Sterling helps translate reporting requirements into tasks that operational and corporate teams can carry out. The emphasis is on clear definitions, usable evidence and an identifiable review path so the next reporting cycle can build on an organised starting point.
