Northbridge Components Ltd is an illustrative UK manufacturer with 620 average employees and £560 million turnover. It passes both relevant tests: 620 is above 500 employees, and £560 million is above £500 million turnover. That means it is likely within the scope of the UK’s TCFD-aligned reporting rules, despite being privately owned.
That is the point many directors miss. Ownership is not the deciding factor. For some large private companies, TCFD reporting requirements UK private companies must follow sit inside the annual strategic report and form part of the company’s statutory reporting obligations.
This guide explains who is covered, what has to be disclosed, how the rules interact with SECR and CSRD, and what a sensible first reporting cycle looks like.
“We’re private, so this doesn’t apply”: TCFD reporting requirements UK private companies
Private status does not create a blanket exemption. Under the Companies Act 2006 climate-related reporting regulations, certain UK private companies and limited liability partnerships must make climate-related financial disclosures when they meet the size thresholds.
For a UK private company, the practical test is generally:
- more than 500 employees; and
- more than £500 million turnover.
Both conditions matter. A private company with 650 employees and £480 million turnover would not meet this particular size test. A business with £700 million turnover but 430 employees would also fall outside it, although other reporting, customer or lender requirements may still apply.
The employee figure is based on the company’s average number of employees during the financial year, rather than a single headcount taken on 31 December. That makes payroll records and the basis of calculation worth preserving.
The regulations apply to accounting periods beginning on or after 6 April 2022. The disclosures usually appear in the strategic report, alongside other information intended to help shareholders understand the company’s performance, position and future prospects.
The caveat: falling outside the statutory threshold does not mean climate risk is irrelevant. Banks, major customers, insurers and procurement teams often ask smaller suppliers for much of the same information.
“Which disclosures are actually required?”
TCFD reporting requirements UK private companies are built around four areas. The UK rules reflect the four pillars originally developed by the Task Force on Climate-related Financial Disclosures.
Governance
Explain how the board oversees climate-related risks and opportunities. Identify the director, committee or management forum responsible, and describe how often the issue reaches the board.
A useful disclosure names the route, not just the responsibility. For example: the chief financial officer owns the reporting process, the risk committee reviews climate risks quarterly, and the full board approves material assumptions in the annual planning cycle.
Strategy
Describe the actual and potential effects of climate-related risks and opportunities on the business model, strategy and financial planning. This can include extreme weather, energy prices, carbon costs, changing customer demand, product regulation and access to finance.
Companies are expected to consider short, medium and long-term time horizons. Those periods should relate to the business. A property developer might use the construction cycle, asset life and lease terms; a food manufacturer may need to consider raw material availability over five, ten and twenty years.
Risk management
Set out how climate risks are identified, assessed and managed, and explain how this process fits with wider enterprise risk management. A climate risk register sitting in the sustainability team with no link to financial risk reporting will look thin.
Metrics and targets
Report the metrics used to assess material climate risks and opportunities. This commonly includes Scope 1 and Scope 2 greenhouse gas emissions, selected Scope 3 categories, energy use, emissions intensity and progress against targets.
The GHG Protocol Corporate Standard is a sensible technical reference for organisational emissions accounting. It is not a substitute for judgement, though. The report should explain boundaries, methods, emission factors, exclusions and any material changes from the previous year.
The caveat: the law does not require every company to publish a perfect climate model. It does require a credible explanation of material risks, governance and performance. False precision is worse than a clear limitation.
“Do we need a separate TCFD report?”
Usually, no. For an in-scope private company, the disclosures are generally included in the strategic report rather than issued as a standalone glossy document. They still need to be easy to find and sufficiently specific for a reader to understand the company’s exposure.
There is also a comply-or-explain feature. If a company has not made one or more required disclosures, it must explain why. “Information is not available” is unlikely to be persuasive on its own. A better explanation identifies the missing data, the reason it is unavailable and the date or process planned to resolve the gap.
Management should also distinguish a disclosure from a marketing statement. Saying that the company is committed to net zero does not explain whether flooding could disrupt a site, whether a carbon price changes a capital investment decision or whether customers are switching to lower-carbon alternatives.
For practical context, the UK Government SECR guidance sets out related energy and greenhouse gas reporting expectations. SECR and TCFD-aligned disclosures can share data, but they are not the same exercise.
If your company needs an independent view of its reporting boundary, evidence and disclosures, speak to our carbon audit team before the annual report timetable becomes compressed.
The caveat: a standalone report can still be useful for lenders, employees and customers. It just should not replace the required information in the strategic report.
“How does this differ from SECR and CSRD?”
These regimes overlap, which is why internal confusion is common. They have different triggers and purposes.
| Reporting requirement | Main trigger | Typical focus | Where it is reported |
|---|---|---|---|
| SECR | Qualifying quoted, large unquoted companies and large LLPs | Energy use, emissions and energy efficiency action | Annual report or energy and carbon section |
| UK TCFD-aligned disclosures | Specified large companies, including qualifying private companies above the 500 employee and £500 million turnover thresholds | Governance, strategy, risk management, metrics and targets | Strategic report |
| EU CSRD | Companies meeting relevant EU or group-scope tests | Double materiality and wider sustainability disclosures | Management report under European Sustainability Reporting Standards |
SECR asks, in broad terms, what energy the organisation used and what emissions resulted. TCFD asks how climate-related risks and opportunities affect decision-making and financial planning. CSRD is a wider European reporting regime based on double materiality, and may affect a UK group through an EU subsidiary, parent or significant EU activity.
Our guide on whether CSRD applies to UK companies is useful where a UK private group sells into Europe or owns an EU entity. Do not assume that being outside the UK’s TCFD threshold ends the analysis.
The caveat: one data collection process can support several regimes, but copying the same paragraph into each report rarely works. Each framework asks a different question of management.
“What should a private company prepare first?”
Start with the reporting perimeter. Confirm the legal entities covered, the financial year, average employee count, turnover and any group or subsidiary considerations. Record the calculation and retain the source documents.
Next, appoint an accountable owner with access to finance, risk, operations, estates, procurement and company secretarial records. Climate reporting fails when it is treated as a sustainability spreadsheet rather than a management control.
A practical first-cycle checklist
- Map sites, assets, products, customers and supply chain dependencies.
- Identify physical risks such as flooding, heat, water stress and storm disruption.
- Identify transition risks such as energy prices, policy changes, carbon costs and customer requirements.
- Link each material risk to a financial effect, time horizon, owner and mitigation.
- Set the organisational and operational emissions boundary.
- Reconcile electricity, fuel and refrigerant data to finance or facilities records.
- Document emission factors, estimates, exclusions and restatements.
- Agree board review points before the annual report is drafted.
Scope 3 data is often the awkward part. Suppliers may not have verified figures, so use a documented hierarchy: supplier-specific data where available, activity-based estimates where practical, and spend-based estimates only where better information cannot yet be obtained. A targeted supplier engagement letter for Scope 3 data can make requests more consistent.
Keep a short evidence file. It should contain board minutes, risk registers, site assessments, energy bills, calculation workbooks, assumptions, target approvals and sign-off records.
The caveat: do not wait for every supplier to provide primary data before reporting. A transparent estimate with a clear improvement plan is more defensible than an unexplained blank.
“Can we just publish our net zero target?”
No. A target is one part of the metrics and targets pillar, not a replacement for the other disclosures. It should also be connected to a baseline, boundary, timeframe, interim milestones and delivery measures.
For example, a company may commit to reducing Scope 1 and 2 emissions by 42 percent by 2030 from a 2023 baseline. That statement becomes more useful when it explains the baseline emissions, the expected contribution from renewable electricity, the capital expenditure required, and what happens if the plan falls behind.
Targets should be considered alongside business decisions. A factory may need to compare electrification, heat recovery, process redesign and renewable power procurement. A logistics company may need to test vehicle replacement timing, charging infrastructure and customer contract terms.
Our net zero roadmap template for small business is aimed at smaller organisations, but the underlying discipline applies here too: assign owners, dates, budgets and measures rather than publishing an ambition in isolation.
Where a company wants externally validated targets, it should understand the distinction between an internal science-aligned target and formal validation through the Science Based Targets initiative. They are not interchangeable claims.
The caveat: a target can be credible without being formally validated, but the report must say what has and has not been independently assessed.
“What happens if we get it wrong?”
The answer is not to inflate certainty. It is to improve governance and evidence before the next reporting cycle. The strategic report is a formal company document, so directors should treat climate disclosures with the same care as other material financial and operational statements.
Ask three questions during review:
- Could a reasonable reader understand how climate change affects this business?
- Could another person reproduce the key emissions and intensity calculations?
- Do the risks, targets and capital plans agree with what management is telling lenders, customers and investors?
Watch for contradictions. A report might describe a site as highly exposed to flood risk while the capital plan contains no resilience spending. It might promise falling emissions while production is expected to double and no intensity metric is shown. These gaps are not automatically unlawful, but they invite uncomfortable questions.
External assurance is not always mandatory for every disclosure, but independent review can test boundaries, calculations, controls and wording. The ISO 14064 standard provides one recognised reference point for greenhouse gas quantification and reporting.
Finally, check the final strategic report against the underlying evidence. Make sure directors know what the numbers mean, what has been estimated and which risks remain unresolved.
The caveat: no reporting process eliminates climate uncertainty. Good reporting makes uncertainty visible so the board can make better decisions about it.
Frequently asked questions
Do all UK private companies have to make TCFD disclosures?
No. The specific UK statutory requirements generally capture private companies that exceed both 500 average employees and £500 million turnover, subject to the detailed legal scope. Smaller companies may still face requests from lenders, customers, insurers or group parents, even when the statutory rules do not apply directly.
Is TCFD reporting mandatory for a private company with £600 million turnover?
Not necessarily. The company also generally needs more than 500 employees to meet the private-company size test. A business with £600 million turnover and 300 employees may be outside that requirement, although SECR, group reporting, customer requirements or overseas rules could create separate obligations.
What should a TCFD report include?
It should address governance, strategy, risk management, and metrics and targets. The information should explain material climate-related risks and opportunities, relevant time horizons, management processes, greenhouse gas metrics, targets and progress. Where a required disclosure is not made, the company should provide a clear explanation rather than leave a silent gap.
Can SECR data be reused for TCFD reporting?
Yes, some energy and emissions data can be reused, which saves time. SECR does not cover the full TCFD-aligned requirement, however. You will still need evidence about board oversight, climate scenarios or time horizons where relevant, material physical and transition risks, financial planning and risk management processes.
