Business Energy and ESG Reporting

Most UK SME ESG reporting efforts start with the energy bill and end with a “we switched to renewable electricity” statement. That’s not ESG reporting — it’s a marketing claim. What investors, institutional customers, and large-company procurement teams actually want when they ask about energy in an ESG context is specific, verifiable, and trended data: how much you consume, how that compares to previous years, what you’re paying for it, how it’s contracted, and what you’re doing about it. The gap between those expectations and the one-line green tariff statement is significant.

What ESG Reporting Actually Requires of UK SMEs

ESG reporting for UK SMEs doesn’t have a single mandatory standard — it has a constellation of overlapping frameworks, customer requirements, and regulatory pressures that collectively determine what you need to produce and for whom. The Task Force on Climate-related Financial Disclosures (TCFD) is the framework that has driven the most significant change in UK ESG reporting since its mandatory adoption for large UK businesses in 2022. TCFD requires disclosure of climate-related risks and opportunities, scenario analysis, and metrics and targets. Large companies must disclose; their suppliers face TCFD-aligned questions from customers who are trying to assess their own supply chain climate risk.

The Corporate Sustainability Reporting Directive (CSRD) is a European Union directive that will progressively require ESG disclosure from EU companies and, critically, from non-EU companies with significant EU business. UK businesses with EU turnover above €150 million may be in scope; UK businesses that are subsidiaries of EU-listed companies are already affected.

How Energy Data Feeds ESG Disclosures

Energy is not one data point in an ESG disclosure — it’s the source of several. Direct energy consumption (in kWh and GJ) is a required metric in GRI Standard 302. The split between renewable and non-renewable energy consumption feeds both GRI 302 and climate-related disclosures. Energy intensity (energy per unit of revenue, per tonne of product, or per square metre of floor space) is the figure that allows year-on-year comparison independent of business growth or contraction. And the associated greenhouse gas emissions — Scope 1, Scope 2 market-based, Scope 2 location-based — flow directly from the energy data.

What this means practically is that energy procurement decisions create ESG data. The contract you sign — its term, its green credentials, its price — determines what your energy spend figures look like, what your renewable energy percentage is, and what your Scope 2 emissions are.

The Gap Between a Green Tariff and Robust ESG Energy Data

One of the more common problems we encounter is businesses that have switched to a green electricity tariff and believe that resolves their energy ESG position. It doesn’t — it addresses market-based Scope 2, but it doesn’t provide the consumption data, intensity metrics, or trend analysis that an ESG questionnaire is looking for. A robust energy ESG position includes: a 12-month rolling energy consumption figure by fuel type, broken down by site if you have multiple locations; year-on-year energy intensity comparison against a relevant denominator; documentation of the renewable backing for your electricity tariff (REGO retirement certificates, not just a supplier claim); and a narrative on actions taken and planned.

The Procurement Angle: Beyond Rate, Into Record-Keeping

For ESG reporting purposes, the value of working with a specialist energy broker extends beyond what you pay per kWh. An organised broker maintains your consumption history, contract documentation, and REGO certificates in a retrievable format. When an ESG questionnaire arrives — from a customer, an investor, or a framework auditor — the underlying energy data is available. We work with clients to ensure that their energy records are as organised as their financial records. This isn’t glamorous. It’s the administration that makes a green claim defensible rather than decorative.

FAQ

A PE investor is asking for our energy consumption and carbon data as part of their pre-investment due diligence. We’ve never tracked this. Where do we start? Start with your energy bills. Request 24 months of consumption data from your electricity and gas suppliers — most suppliers will provide this through their business portal. Use BEIS emissions factors to convert consumption to Scope 1 (gas) and Scope 2 (electricity) CO₂e. Calculate an intensity metric: emissions per £ of revenue for the two years, which gives you a trend. This won’t be a polished ESG report, but it will give the investor the substantive information they need.

We supply to a large housebuilder that has asked us to complete a sustainability questionnaire with a section on our energy management system. We don’t have one. What do we say? Say so, and explain what you do have. A formal energy management system — particularly ISO 50001 — is unlikely to be expected of an SME supplier, and a sophisticated buyer knows this. What they’re assessing is whether you have any systematic approach to energy: do you know your consumption, do you have an energy contract you’ve actively chosen, do you track it over time? Frame your answer around what you do, rather than focusing on the label you don’t have.

We’ve been asked to complete the Carbon Disclosure Project (CDP) questionnaire by a major customer. Is this required and how do we complete it? CDP participation is voluntary for SMEs but is increasingly requested by large companies seeking to assess their supply chain emissions. CDP has a specific SME-focused disclosure option (the Supply Chain Module) that requires less than the full corporate questionnaire. The core requirements are Scope 1 and 2 data, your climate governance approach, and whether you have emissions reduction targets. If you’ve been recording your energy consumption consistently, you have most of what you need.
