How to Prepare a UK SRS S1 Report: Complete Step-by-Step Guide

Educational practitioner material. Illustrative examples and wording require adaptation and technical review.

UK SRS S1 asks for material information about sustainability-related risks and opportunities that could reasonably be expected to affect an entity’s prospects. That objective reaches across the business model, value chain, strategy, risk management, finance, data systems and governance. A report assembled only by collecting existing ESG text will usually miss one of three things: completeness of the risk and opportunity universe, connectivity to financial planning, or evidence supporting the published claim.

The most efficient approach is to design the reporting basis, decision records and control trail before writing narrative. The article below uses a twelve-month cycle, but the same stages can be compressed or extended. The critical point is sequence: scope before collection, identification before materiality, materiality before disclosure design, and evidence before approval.

Create a short Basis of Preparation decision paper. It should identify the reporting entity, reporting period, standards and editions applied, whether application is voluntary or required by a specific route, the location of the disclosures, the intended compliance or alignment wording, reliefs expected to be used, and the approval body. The reporting entity should be the same as for the related financial statements, and the sustainability-related financial disclosures should cover the same reporting period and be published at the same time.

Do not leave the claim until the final legal review. A full UK SRS S1 compliance statement requires compliance with all applicable requirements. Climate-only use under paragraph E3 changes that outcome and must be designed into the basis from the start.

Set a governance model that reflects how the organisation actually operates. Name the board or committee that oversees sustainability-related risks and opportunities, the executives accountable for the reporting process, the owners of each material risk or opportunity, data owners, preparers, reviewers and the final approver. Terms of reference, role descriptions, reporting calendars and information flows should support the governance disclosure rather than being created after the narrative is drafted.

Appoint one accountable reporting owner and a cross-functional steering group spanning sustainability, finance, risk, strategy, legal, company secretariat, investor relations and internal audit.

Create a RACI for identification, materiality, financial effects, metrics, controls, drafting, technical review and board approval.

Open a decision log, source register, risk and opportunity register, data and evidence register, relief register and issue log.

Define change control: who can change a methodology, boundary, estimate, target or claim, and what reapproval is required.

The starting population is not a generic ESG topic list. Map the activities, products and services, geographies, assets, workforce, key customers and suppliers, distribution routes, financing relationships, joint ventures and other business relationships that shape cash generation. Then identify the resources and relationships the entity depends on and affects. UK SRS S1 makes clear that dependencies and impacts may exist throughout the value chain and can give rise to risks and opportunities for the entity.

The output should be a value-chain map at a level useful for decision-making, with known data gaps visible. It need not be a perfect end-to-end traceability exercise. The standard uses reasonable and supportable information available without undue cost or effort and does not require an exhaustive search. However, a team should not use that principle to ignore information already used in strategy, risk management, financial planning, procurement or operations.

Run structured identification workshops by business model and value-chain segment. Consider dependencies, impacts and external change; then trace each issue to a plausible effect on cash flows, access to finance or cost of capital over the short, medium or long term. Record both risks and opportunities. A positive initiative is not automatically an opportunity under UK SRS S1: the team needs a credible pathway to the entity’s prospects.

Internal inputs: enterprise risk register, strategy, budgets, capital allocation, asset reviews, procurement, workforce data, legal matters, customer insight, complaints and internal audit.

External inputs: law and policy, market and technology change, scientific and sector evidence, credit and insurance information, investor questions, peer experience and relevant statistics.

Value-chain inputs: supplier and customer concentration, location and commodity exposure, contractual dependencies, outsourced activities, product use and end-of-life effects.

Completeness challenge: sectors, geographies, time horizons and low-probability/high-impact outcomes that the first pass may have missed.

For each identified risk or opportunity, first identify the information that could be relevant under the specifically applicable UK SRS or the sources of guidance in UK SRS S1. Then assess whether that information, individually or in combination, is material in the context of the complete sustainability-related financial disclosures. The test is whether omission, misstatement or obscuring could reasonably be expected to influence the decisions of primary users.

Document both quantitative and qualitative factors. Consider the nature and magnitude of effects, the range and likelihood of uncertain outcomes, timing, aggregation and presentation. Do not apply one universal monetary threshold. A low-probability, high-impact outcome or highly scrutinised qualitative matter may be material even where a single expected-value figure is small.

UK SRS S1 and UK SRS S2 are designed to be applied together. Unless the entity deliberately uses the climate-only provision in paragraph E3, UK SRS S1 covers all material sustainability-related risks and opportunities while UK SRS S2 supplies the climate-specific requirements. Climate identification, scenario analysis, resilience, greenhouse gas emissions, industry metrics and targets therefore need a dedicated workstream that remains connected to the S1 materiality, finance and governance decisions.

For non-climate matters without a specific UK SRS, apply the sources of guidance in paragraphs 54-59. The final UK standard permits, rather than requires, reference to SASB materials. Record which industry or other sources were used, why they are relevant, and what entity-specific information was added.

Design the outline around connected decisions, not around copying the order of standard paragraphs. For example, the material risk table should link to strategy responses, financial effects, metrics and the responsible governance body. Cross-references can reduce duplication, but only when they are precise, accessible, published at the same time and do not obscure material information.

Build a risk-to-finance bridge for every material risk and opportunity. Start with the operational or strategic pathway, identify affected revenue, costs, assets, liabilities, cash flows, access to finance or cost of capital, and then connect the analysis to budgets, forecasts, capital expenditure, impairment testing, provisions, useful lives, insurance, financing plans or other relevant financial processes. The analysis may be quantitative or qualitative depending on the facts and the reliefs in paragraphs 36-40, but the reason for any inability to quantify should be transparent.

Current financial effects: effects recognised or experienced in the reporting period.

Anticipated financial effects: possible effects over the entity’s defined time horizons.

Planning connection: assumptions, ranges and scenarios consistent, to the extent possible, with approved plans and the financial statements.

Uncertainty: methods, assumptions, limitations and significant estimation uncertainty clearly disclosed.

Create a metric register before requesting data. For each metric, record the definition, unit, boundary, period, source, method, assumptions, estimates, responsible owner, reviewer, controls, target linkage, prior-period comparability and any restatement policy. Metrics from external sources should identify the source. Entity-developed metrics require enough explanation for users to understand what is measured and how.

Industry information is not optional merely because use of SASB materials is optional. UK SRS S1 requires metrics associated with the business models, activities or common features that characterise participation in an industry. The team should document the industry sources considered and the basis for selecting, adapting or rejecting candidate metrics.

Apply a control framework proportionate to the risk of material misstatement. Core controls normally cover source-system access, completeness, methodology approval, calculation and model review, estimate governance, reconciliations, period and boundary checks, segregation of preparation and review, evidence retention, disclosure tie-outs, change control and management representations. Internal audit or an independent readiness review can test the design before year end.

Draft from approved registers and decision records. Use a Basis of Preparation, a material risk and opportunity overview, the four pillars, metric and target notes, judgements and uncertainty, relief disclosures and exact cross-references. Keep management information and public disclosure consistent, but do not publish confidential evidence merely to prove that a control exists.

Run at least three reviews: a technical claim review against the standards and source anchors; a finance and connectivity review against the annual report and financial statements; and a red-team review looking for omitted conditions, unsupported compliance language, obscured material information, inconsistent periods, weak evidence and overconfident examples.

The final approval paper should state the exact documents and claim being approved, material judgements, reliefs, open limitations, financial-effect conclusions, control assessment, assurance scope, changes since committee review and conditions attached to approval. Named executive owners should provide representations over completeness and accuracy. The board should be able to explain not only what is disclosed, but how the organisation concluded that the report is complete and decision-useful.

A twelve-month reporting journey that keeps scope, materiality, finance, controls and approval connected. The sequence is illustrative and should be adapted to the entity's reporting timetable.

Teaching point: the reporting system changed the answer. A pre-existing ESG content list would not have demonstrated completeness, financial connectivity or a supportable claim.
