SECR · Streamlined Energy and Carbon Reporting
SECR compliance: a specialist guide to the requirements
SECR compliance means reporting energy use and greenhouse gas emissions in the annual report, under rules created by SI 2018/1155 and in force since 1 April 2019.
This specialist guide covers who is in scope, the exact size test, what must be disclosed, when, and what happens if it goes wrong.
What it is
What SECR compliance requires
Streamlined Energy and Carbon Reporting is the UK’s annual energy and carbon disclosure for larger companies and LLPs.
It was created by SI 2018/1155, which inserted the rules into Schedule 7 of SI 2008/410 for companies and into SI 2008/1911 for LLPs.
It replaced the CRC Energy Efficiency Scheme, which closed after the 2018–19 compliance year.
SECR is backward-looking: it reports what was used and emitted, and it requires no target, no transition plan and no assurance.
For the step-by-step reporting mechanics, see the SECR reporting guide on uksrs.org.uk; for deadlines and thresholds in depth, the dedicated SECR guidance site covers them.

Scope
Who is in scope for SECR
SECR has three populations, and each has its own test.
Quoted companies are in scope at any size, under Schedule 7, Part 7.
Unquoted companies are in scope unless exempt under paragraph 20B, which exempts a company that satisfies two or more of: turnover not more than £36 million, balance sheet total not more than £18 million, and not more than 250 employees.
Put the other way round, an unquoted company is in scope only if it exceeds at least two of the three limits.
A company sitting exactly on £36 million of turnover is inside the exemption limb for that condition.
LLPs use the same figures, written into regulation 12B of SI 2008/1911 rather than paragraph 20B.
A parent company uses the group test in paragraph 20C: aggregate turnover of £36 million net (or £43.2 million gross), aggregate balance sheet of £18 million net (or £21.6 million gross), and 250 employees.
An AIM company is unquoted under section 385 of the Companies Act 2006, so it is caught only by the size test.
Why the April 2025 uplift did not move SECR
The Companies Act size thresholds rose on 6 April 2025, but paragraph 20B carries its own table and never cross-refers to them.
The uplifting instrument, SI 2024/1303, omitted Schedule 7 Parts 3 and 4 and left Part 7A alone.
So a company can now be medium-sized for its accounts and in scope for SECR on the same figures.
The government’s own 2019 SECR guidance still describes the LLP test as based on sections 465 and 466; follow the figures printed beside that sentence, not the cross-reference.

Disclosures
What a SECR disclosure must contain
Quoted and unquoted companies report different things, and the difference is not only geography.
| Element | Quoted company (Part 7) | Unquoted company or LLP (Part 7A) |
|---|---|---|
| Emissions | From the combustion of fuel and the operation of any facility (¶15(2)) | From the combustion of gas and the consumption of fuel for transport (¶20D(1)) |
| Purchased energy | Electricity, heat, steam or cooling (¶15(3)) | Electricity only (¶20D(2)) |
| Energy use | Aggregate kWh (¶15(3A)) | Aggregate kWh (¶20D(3)) |
| Geography | Global, with the proportion relating to the UK and offshore area (¶15(3B)–(3C)) | May exclude energy and emissions outside the UK and offshore area (¶20D(5)) |
| Efficiency measures | Principal measures taken in the year (¶15(3D)) | Principal measures taken in the year (¶20D(4)) |
| Methodology | ¶16 | ¶20F |
| Intensity ratio | At least one, emissions to a quantifiable factor (¶17) | At least one, emissions to a quantifiable factor (¶20G) |
| Comparatives | ¶18 and ¶18A — emissions and the energy limb | ¶20H |
The Regulations require at least one ratio of emissions to a quantifiable factor associated with the company’s activities.
Revenue, floor area, headcount or tonnes of product all satisfy it; there is no prescribed ratio.
A company that consumed 40,000 kWh or less may omit the energy and emissions disclosures only if the report states that reason.
For unquoted companies and LLPs the test is energy consumed in the United Kingdom; for quoted companies it is not UK-qualified.
Emissions are usually calculated with the annual government conversion factors, and the methodology used must be stated.
Scope 3 is required only in one narrow form: unquoted companies and LLPs report the consumption of fuel for transport; quoted companies have no Scope 3 limb at all.
The same inventory can serve other regimes — the energy data behind ESOS Phase 4, and the Scope 1 and 2 figures UK SRS asks for — which is why many organisations treat SECR as part of wider emissions compliance.
Where and when
Where SECR sits, and the filing deadline
For a company, the SECR disclosure sits in the directors’ report, part of the annual report filed at Companies House.
An LLP has no directors’ report, so it prepares a separate energy and carbon report, approved by the members.
SECR therefore has no deadline of its own: it follows the accounts filing period in section 442 of the Companies Act 2006.
Companies House is clear that a filing deadline falling on a Sunday or bank holiday does not move.
Because the disclosure needs a full year of energy data, the practical work starts well before the year end, not at filing.
The government’s September 2026 Modernising corporate reporting consultation proposes to abolish the directors’ report, which would move SECR disclosures elsewhere in the annual report; it is a proposal, and it does not change the duty.
| Company | File accounts within |
|---|---|
| Private company | 9 months of the year end |
| Public company | 6 months of the year end |
Enforcement
What happens if SECR goes wrong
SECR creates no penalty of its own: Schedule 7 Parts 7 and 7A contain no offence and no fine.
The consequences come from the Companies Act 2006: under section 419(3)–(4), a director who approves a directors’ report knowing it does not comply, or reckless as to whether it complies, commits an offence.
The FRC is authorised to apply to court for a defective report to be revised, and has resolved every case to date without needing a court order.
Section 463 protects directors from liability to anyone other than the company for statements in the report.
Late filing is a separate matter: Companies House charges a civil penalty on the company for filing the accounts late.
DESNZ’s 2026 post-implementation review described enforcement as light-touch and estimated suspected non-compliance at 14–23%.
Section 463 of the Companies Act 2006 limits directors’ liability for statements in the directors’ report to the company, and only for knowing or reckless misstatements.
It is a safe harbour, and quoting it as SECR’s penalty is a common error.
SECR compliance support
When to bring in a SECR compliance specialist
DESNZ’s evaluation found 19,900 organisations in SECR’s scope — 76% more than the 2018 impact assessment predicted — and that 56% of those complying incurred external costs.
Specialist SECR compliance support tends to earn its keep in four situations: a company newly in scope, a group with a parent-level test, a quoted company reporting globally, and a first year after an acquisition or a change of reporting boundary.
No credential exists for SECR work, so a specialist is judged on method, not on a register.
How to choose and check one is set out in our guide to choosing a SECR compliance specialist, and what an engagement involves is on the SECR consultancy page.
SECR is one strand of UK carbon compliance, alongside ESOS and UK SRS, and our sister title covers the UK sustainability reporting standards more widely.

Frequently asked
SECR compliance — frequently asked
Who has to comply with SECR?
Three groups. Every quoted company, at any size. Unquoted companies — including AIM companies — that exceed at least two of three limits: turnover of £36 million, a balance sheet total of £18 million and 250 employees. And LLPs that exceed the same limits. An unquoted company is exempt where it satisfies two or more of the “not more than” conditions in Schedule 7, paragraph 20B of SI 2008/410.
Did the SECR thresholds change in April 2025?
No. The Companies Act size thresholds rose on 6 April 2025, but SECR’s test is written into its own table in paragraph 20B and never cross-refers to them. The amending instrument, SI 2024/1303, left Part 7A untouched. Since then a company can be medium-sized for its accounts and still in scope for SECR on the same figures.
What must be disclosed under SECR?
For an unquoted company: UK energy use in kWh, the emissions from gas, purchased electricity and transport fuel, at least one intensity ratio, the methodology, a narrative of the principal energy efficiency measures taken, and the previous year’s figures. A quoted company reports its global emissions from fuel combustion, facilities and purchased electricity, heat, steam or cooling, the energy in kWh, and the proportion relating to the UK and offshore area.
Where does SECR reporting go?
In the directors’ report, for companies — or in a separate energy and carbon report, for LLPs, which have no directors’ report. The government’s Modernising corporate reporting consultation of September 2026 proposes to remove the directors’ report, which would move SECR disclosures elsewhere in the annual report; that is a proposal, and the duty itself would not change.
Is there a SECR relief for low energy use?
Yes, but it is relief from disclosure, not from SECR. An unquoted company or LLP that consumed 40,000 kWh of energy or less in the United Kingdom in the period may omit the energy and emissions disclosures, provided the report states that the information is not disclosed for that reason. A quoted company has the same relief without the UK qualifier.
When is the SECR filing deadline?
SECR sits in the annual report, so it follows the accounts filing deadline in section 442 of the Companies Act 2006: nine months after the end of the accounting reference period for a private company and six months for a public company. Companies House is clear that a deadline falling on a weekend or bank holiday does not move.
Does SECR need to be audited or assured?
No. Nothing in Schedule 7 requires assurance or verification of SECR figures, and the government’s guidance says there is no statutory requirement to have environmental information audited. The statutory auditor reports only on whether the directors’ report is consistent with the accounts and prepared in accordance with the law.
What is the penalty for not complying with SECR?
SECR has no penalty of its own. A director who approves a directors’ report knowing it does not comply, or reckless as to whether it complies, commits an offence under section 419 of the Companies Act 2006, and the FRC can apply to court for a defective report to be revised. Late filing of the accounts attracts Companies House’s civil penalties.
Is an AIM company quoted for SECR?
No. A quoted company under section 385 of the Companies Act 2006 is one whose equity is on the Official List, officially listed in an EEA State, or admitted to dealing on the New York Stock Exchange or Nasdaq. AIM is none of these, so an AIM company is unquoted and in scope only if it exceeds at least two of the size limits.
