Illustrative example: Northstar Components Ltd records net turnover of €160 million in each of two consecutive financial years and generates €45 million through an EU branch. Because €45 million is above the €40 million branch threshold, Northstar may meet the non-EU company route into CSRD reporting, assuming the other conditions are met. That is the sort of calculation UK finance teams need to make.
So, does CSRD apply to UK companies? Not simply because a business is registered in the United Kingdom. The answer depends on EU turnover, an EU subsidiary or branch, the company structure and the timing of the rules. Even where the law does not apply directly, an in-scope customer or parent company may still ask for detailed emissions and sustainability data.
This guide separates direct legal scope from the commercial pressure many UK businesses are already feeling.
“We are a UK company, so CSRD cannot affect us”
A London registered company with no EU subsidiary, no EU branch and no significant EU turnover will usually sit outside the direct scope of CSRD. Brexit did not create a general obligation for all UK companies to report under the EU framework.
The position changes when the business has a substantial EU presence. A UK parent can be caught through its own EU operations, through a listed EU subsidiary or through the non-EU undertaking rules. The legal test is not based on where the directors sit or where the annual accounts are filed.
The EU CSRD overview is the best starting point for the current framework, but the detail needs checking against the latest amendments. The EU has proposed changes to timing and scope, so do not build a three-year compliance plan from an old blog post.
Contrarian point: being outside direct scope is not the same as being able to ignore sustainability reporting. A large EU customer can impose a data requirement through its procurement contract long before a regulator contacts you.
“Which UK companies can fall directly within CSRD?”
Consider a UK engineering group with a German subsidiary, a French sales branch and €175 million of annual EU turnover. Its parent may not report simply because it owns EU assets, but the group could meet the non-EU undertaking test if it exceeds the relevant EU turnover threshold and has a qualifying EU subsidiary or branch.
For non-EU undertakings, the commonly cited CSRD test is more than €150 million net turnover in the EU for each of the previous two consecutive financial years, combined with either a qualifying EU subsidiary or an EU branch meeting its own threshold. The branch route generally involves more than €40 million net turnover in the preceding financial year. A large or listed EU subsidiary can also be relevant.
These thresholds are not the only question. The reporting obligation may sit with the EU subsidiary, the branch or the wider non-EU undertaking, depending on the facts and the applicable phase-in rules. Group structures should be mapped before anyone decides that the answer is “no”.
| Situation | Likely position | What to check |
|---|---|---|
| UK company with no EU operations and modest EU sales | Usually outside direct CSRD scope | Customer contracts, investor requests and other reporting duties |
| UK parent with a large or listed EU subsidiary | EU subsidiary may have its own reporting obligation | Size, listing status, consolidation and exemption rules |
| UK group with more than €150 million EU turnover for two years | Potential non-EU undertaking scope | Qualifying EU subsidiary or branch and reporting timetable |
| UK company supplying an in-scope EU manufacturer | Usually indirect commercial pressure | Requested Scope 1, Scope 2, Scope 3 and policy data |
Contrarian point: the €150 million figure is not a universal “CSRD threshold for UK companies”. It is one part of a wider test. Quoting it without checking the subsidiary or branch condition produces false certainty.
“Our EU subsidiary is small, so the parent does not need to care”
Take a UK retailer with a small Irish subsidiary that is not listed and does not meet the relevant size tests. The subsidiary may not have to publish a full sustainability statement, but the group still needs to understand whether the parent’s EU turnover and structure create an obligation elsewhere.
There are also consolidation issues. An EU subsidiary may be exempt from preparing its own sustainability statement if it is included in a parent undertaking’s consolidated reporting, subject to the conditions and information required by the rules. That exemption does not mean the data disappears. It usually means the data is reported at group level.
Finance directors should therefore prepare a simple legal-entity map. List each UK company, EU subsidiary, branch, turnover by geography, listing status, ownership percentage and whether accounts are consolidated. Then record which entity, if any, is expected to sign off the sustainability information.
If the group currently relies on disconnected spreadsheets, a review of carbon accounting spreadsheets versus software for SMEs can help expose where entity-level data is being lost.
Contrarian point: a small subsidiary can still create a large reporting workload. Its electricity, employees, buildings and purchased goods may all feed into group metrics even when it publishes nothing independently.
“If CSRD does not apply, we do not need Scope 3 data”
A UK packaging supplier may receive a customer questionnaire asking for purchased materials, transport, waste and product-use information. The supplier is not necessarily a CSRD reporter, but its customer may need those figures for value-chain disclosures.
CSRD reporting is built around double materiality. That means a company considers both how sustainability matters affect the business and how the business affects people and the environment. Value-chain information is therefore not a side issue, particularly for emissions, labour conditions, resource use and pollution.
UK suppliers should expect requests for:
- Scope 1 and Scope 2 emissions, with the boundary and calculation method stated;
- selected Scope 3 categories, often purchased goods, transport, waste and business travel;
- energy consumption, renewable electricity evidence and operational sites;
- policies, targets, incidents and environmental certifications; and
- activity data that can be traced to invoices, meters, procurement records or logistics systems.
Do not send an impressive number with no audit trail. Use the supplier engagement letter for Scope 3 data approach to set out the boundary, units, evidence and response deadline clearly.
Contrarian point: not every customer request deserves a bespoke carbon model. For a small supplier, a transparent spend-based estimate with stated assumptions may be more useful than a late, expensive attempt at perfect product-level data.

“We already report under SECR, so that should cover CSRD”
A UK medium-sized company may already include energy use and greenhouse gas emissions in its annual report under the Streamlined Energy and Carbon Reporting regime. That is useful groundwork, but it is not a substitute for CSRD.
SECR is narrower. It focuses mainly on energy use, emissions and related energy-efficiency information for qualifying companies and limited liability partnerships. CSRD covers a much broader set of environmental, social and governance topics, with prescribed European Sustainability Reporting Standards and a materiality assessment.
Check the UK Government SECR guidance for the UK obligation, then compare it with the information your EU group or customer is requesting. The overlap is helpful, but the evidential standard, controls and subject matter can be very different.
Keep the boundary decisions consistent. The GHG Protocol Corporate Standard remains a familiar basis for corporate greenhouse gas accounting, although a CSRD report may require additional disclosures and explanations beyond the emissions inventory.
Contrarian point: SECR can be enough for a company with no EU exposure and no wider reporting commitment. Do not buy a full CSRD system simply because a sales brochure uses the acronym.
“What should a UK company do before it knows the answer?”
One UK manufacturer reduced uncertainty by asking its auditor and group finance team for the same five items: EU turnover by year, entity structure, branch turnover, listing status and consolidation treatment. That took an afternoon and was more valuable than commissioning a report before the scope question had been answered.
Use this order of work:
- Map every UK and EU legal entity, branch and reporting relationship.
- Calculate EU net turnover for each of the last two financial years using the group’s agreed accounting basis.
- Check whether any EU subsidiary is large, listed or included in a parent’s consolidated reporting.
- Identify the emissions, workforce, policy and value-chain data already available.
- Ask key EU customers and lenders which metrics they will require, by what date and in what format.
- Document the conclusion, assumptions and date of review because the EU rules may change.
For businesses outside direct CSRD scope, a sensible response is often a proportionate carbon inventory, a data-control process and a short reduction plan. The net zero roadmap template for small business can help turn a customer questionnaire into a practical internal programme rather than a one-off scramble.
Start with evidence. Electricity bills, fuel records, procurement spend, fleet mileage and waste invoices are more valuable than a polished sustainability page unsupported by records.
Contrarian point: waiting for absolute legal certainty can be expensive. But rushing into a full CSRD implementation without confirming scope is equally wasteful. First establish the legal route, then build controls in proportion to the risk.
Does CSRD apply to UK companies? The practical answer
A UK company is not automatically covered by CSRD. Direct scope is most likely where a non-EU group exceeds the relevant EU turnover test and has a qualifying EU subsidiary or branch, or where an EU entity has its own reporting obligation.
Outside those cases, the main exposure is commercial. An EU customer, parent company, lender or investor may need reliable data from the UK business for its own report. Treat that request as a signal to improve the underlying records, not as proof that your company is legally subject to CSRD.
Review the position annually and whenever the group acquires an EU business, opens a branch or changes its turnover profile. Regulatory scope can move faster than internal reporting systems.
FAQs
Does CSRD apply to a UK company with EU customers?
Usually not solely because it sells to EU customers. Direct CSRD scope generally depends on the company’s structure, EU turnover and qualifying EU subsidiary or branch. However, an EU customer may request emissions, workforce and policy data for its value-chain reporting. That commercial request can be demanding even when the UK supplier has no direct filing obligation.
What is the CSRD turnover threshold for a UK company?
For a non-EU undertaking, the commonly cited route involves more than €150 million net turnover in the EU for each of the previous two consecutive financial years, plus a qualifying EU subsidiary or branch. A branch route commonly refers to more than €40 million turnover in the preceding financial year. Check the latest EU rules before relying on these figures.
Is SECR the same as CSRD?
No. SECR is a UK reporting regime focused mainly on energy use, greenhouse gas emissions and energy-efficiency information for qualifying organisations. CSRD covers wider environmental, social and governance matters and uses European Sustainability Reporting Standards. SECR data can provide a useful starting point, but it will not normally satisfy a complete CSRD reporting requirement.
What data should a UK supplier prepare for an EU customer?
Prepare Scope 1 and Scope 2 emissions, relevant Scope 3 categories, energy consumption, renewable electricity evidence, waste, transport and basic policies. Keep source records such as invoices, meter readings and mileage logs. State the organisational boundary, reporting year, emission factors and estimates used. A transparent estimate is better than an unsupported figure presented as precise.
