SECR thresholds · who must report
SECR thresholds: exceed two of three
The SECR thresholds catch an unquoted company or an LLP that exceeds at least two of three limits: turnover of £36 million, a balance sheet total of £18 million and 250 employees, under Schedule 7 paragraph 20B.
Quoted companies have no threshold at all, and a change of size only counts once it has lasted two years.
The test did not move when the Companies Act size limits rose in April 2025.
Three populations
Three populations, three threshold homes
SECR applies to three kinds of organisation, and each finds its threshold in a different place.
Quoted companies are caught because they are quoted: paragraph 15(1) applies Part 7 “if the company is a quoted company”, with no turnover, balance sheet or headcount test.
A quoted company is one whose equity share capital is on the Official List, officially listed in an EEA State, or admitted to dealing on the New York Stock Exchange or Nasdaq, under section 385 of the Companies Act 2006.
The London Stock Exchange says in its own Admission and Disclosure Standards that securities admitted to AIM are not admitted to the Official List.
So an AIM company is unquoted for SECR, faces the size test, and if it is in scope reports on the unquoted basis.
Unquoted companies are tested under Part 7A, and LLPs under their own instrument with the same figures.
Which organisations are exempt, and which reliefs apply once you are in, is set out on SECR eligibility.
| Population | Size test | Where it is |
|---|---|---|
| Quoted companies | None | Sch 7 ¶15(1) |
| Unquoted companies | Exceed two of £36m / £18m / 250 | Sch 7 ¶20B, ¶20C |
| LLPs | Exceed two of £36m / £18m / 250 | SI 2008/1911 reg 12B |
The test, word for word
An exemption, written in “not more than”
Paragraph 20B does not say who is in scope: it says who is exempt.
A company that is not a parent is exempt in a year in which it satisfies two or more of the three conditions below.
| Limb | Exemption condition (¶20B(2)) | In scope when | How it is measured (¶20B(3)) |
|---|---|---|---|
| Turnover | Not more than £36 million | More than £36 million | The accounts figure; a financial year that is not a year is proportionately adjusted |
| Balance sheet total | Not more than £18 million | More than £18 million | The aggregate of the amounts shown as assets — liabilities are not deducted |
| Number of employees | Not more than 250 | More than 250 | Monthly count of persons under contracts of service, added and divided by the months in the year |
Turn the exemption round and a company is in scope when it exceeds at least two of the three limits.
Exceeding only one is not enough, because the other two still satisfy the exemption.
A company sitting exactly on a limit has not exceeded it: £36 million of turnover is “not more than £36 million”.
Only turnover is adjusted for a short or long financial year; the balance sheet total and the headcount are not.
The headcount is a count of people, so a part-time employee counts as one person, not as a fraction.
Because the balance sheet total is every asset shown, cash, receivables, property and financial instruments held as assets all count towards it.
The government’s own post-implementation review describes scope as turnover of “£36 million or more … and/or 250 or more employees”.
The figures are right, but the shape is not the legal test: the law exempts a company that stays at or under two of three limits.
Timing
A change of size counts only after two years
The consecutive-year rule sits in paragraph 20B(1), and it works in both directions.
In a company’s first financial year, the exemption depends on that year alone.
After that, a company is exempt if it meets the conditions this year and met them last year.
It is also exempt if it meets them this year and was exempt last year.
And it stays exempt in a year it exceeds the limits, if it met the conditions and was exempt the year before.
So a growing company comes into scope in its second consecutive year over the limits, not the first.
A shrinking company that was in scope leaves only after two consecutive years under them.
The LLP test carries the same three-limb rule in modified section 415A(1).
The test is applied to the financial year as a whole, so crossing a limit part-way through a year changes nothing until the year’s figures are known.
Illustrative: a company that grows
- FY2024Under the limits — exempt
It satisfies two or more conditions.
- FY2025Over the limits — still exempt
It met the conditions in FY2024 and was exempt in FY2024 (¶20B(1)(b)(iii)).
- FY2026Over the limits again — in scope
Two consecutive years over: no limb of the exemption is left.

Worked examples
Four companies, tested
Illustrative figures, not real companies, each assumed to be in the same position the year before.
In scope
Manufacturer
Turnover £45m · balance sheet £15m · 280 employees
Exceeds the turnover and employee limits: two of three.
Exempt
Professional services firm
Turnover £25m · balance sheet £22m · 180 employees
Exceeds only the balance sheet limit, so it still satisfies two conditions.
Exempt
Property investor
Turnover £8m · balance sheet £85m · 45 employees
A very large balance sheet is one limb; the other two are met.
In scope
Technology company
Turnover £40m · balance sheet £20m · 150 employees
Exceeds turnover and balance sheet: two of three.
The manufacturer and the technology company are both under £54 million turnover, so both may be medium-sized for their accounts since April 2025 — and both are still in SECR scope.
Once in scope, what goes in the report is set out on SECR requirements, and when it is due on SECR deadlines.
Groups
Parents test the group; subsidiaries may shelter
A parent company is not tested on its own figures but on the group it heads, under paragraph 20C of Part 7A.
The aggregate figures are built by adding up each group member’s figures, determined as paragraph 20B determines them.
“Net” means after the set-offs that eliminate group transactions, “gross” means before them, and a group may satisfy each limb on either basis.
Each subsidiary’s figures come from its own accounts for the year ending with the parent’s, or its last year ending before it.
The same consecutive-year rule applies to the group, in paragraph 20C(1).
A subsidiary that is in scope on its own figures need not report itself if paragraph 20A(2) applies.
That needs the subsidiary to be included in the group report of a parent whose financial year ends at the same time as or before its own, and the group report to comply.
The shelter fails where the group report relies on the seriously prejudicial relief.
The DESNZ evaluation found that most in-scope entities, about 14,000 of 19,900, must report themselves and cannot rely on a parent’s disclosure.
| Aggregate limb (¶20C(2)) | Net | Gross |
|---|---|---|
| Turnover | Not more than £36m | Not more than £43.2m |
| Balance sheet total | Not more than £18m | Not more than £21.6m |
| Employees | Not more than 250 | Not more than 250 |
The April 2025 divergence
The Companies Act limits moved. SECR’s did not.
| Test | Turnover | Balance sheet total | Employees | Since |
|---|---|---|---|---|
| SECR, single company (¶20B) | £36m | £18m | 250 | 1 April 2019 |
| SECR, group (¶20C) | £36m net / £43.2m gross | £18m net / £21.6m gross | 250 | 1 April 2019 |
| Companies Act medium-sized (s.465) | £54m | £27m | 250 | 6 April 2025 |
| Companies Act medium-sized group (s.466) | £54m net / £64m gross | £27m net / £32m gross | 250 | 6 April 2025 |
The Companies Act’s own size classes — small in section 382, medium-sized in section 465 — decide which accounts a company may file.
SECR does not use them.
Paragraph 20B writes £36 million, £18 million and 250 into its own table, and nothing in Part 7A cross-refers to section 465 or 466.
The uplifting instrument’s regulation 5(3) amended Parts 3 and 4 of Schedule 7 and left Part 7A alone.
The SECR group figures of £43.2 million and £21.6 million gross are the old Companies Act figures, frozen into SECR in 2019, and they are still live law — in SECR only.
The practical consequence: since 6 April 2025 a company can be medium-sized for its accounts and still in scope for SECR, on the same figures.
The 2018 regulations matched the Companies Act figures of the day, which is why the two were easy to confuse until 2025.
LLPs
Same figures, a different instrument
An LLP’s threshold is not paragraph 20B, which regulation 12B of SI 2008/1911 expressly switches off for LLPs.
Its test is in modified section 415A: turnover not more than £36 million, balance sheet total not more than £18 million, not more than 250 employees, two or more to be met.
An LLP group uses £36 million net or £43.2 million gross and £18 million net or £21.6 million gross, like a company group.
The government’s 2019 guidance describes the LLP threshold as based on sections 465 and 466 of the Companies Act, a cross-reference that has been misleading since April 2025 — the figures printed beside it are the right ones, as SECR for LLPs explains.
Our sister title’s guide to SECR reporting thresholds covers the same ground from an editorial angle.
Not to be confused with
Four thresholds that look alike
| Regime | Test | Shape |
|---|---|---|
| SECR (unquoted, LLPs) | £36m turnover · £18m balance sheet · 250 employees | Exceed two of three |
| ESOS Phase 4 | At least 250 employees, or turnover over £44m and balance sheet over £38m | Either / or, not two of three |
| Modern Slavery Act s.54 | Total turnover of £36m, including subsidiaries | One turnover test |
| FCA UK SRS rules (PS26/19) | Listing category: UKLR 6, 14, 15, 16 and 22 | No size test |
The Modern Slavery Act’s £36 million and SECR’s £36 million are a coincidence of drafting, not a cross-reference, and the tests work differently.
Being in SECR scope tells you nothing about ESOS, and the reverse is equally true.
The FCA’s final rules finalise CP26/5 and require listed companies in scope to report against UK SRS on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027 — a listing-rule duty that sits beside SECR, not in place of it.
How the two regimes overlap for a quoted company is covered on SECR vs UK SRS, and the ESOS comparison on ESOS vs SECR.
Check your figures
Run the test on your own numbers
The checker applies paragraphs 15, 20A, 20B and 20C and regulation 12B as written, including the consecutive-year rule.
Enter the figures from this year’s accounts and last year’s, and say whether the company reported last year.
It does not deal with the 40,000 kWh relief, because that relief does not take anyone out of scope: an in-scope company that consumed 40,000 kWh or less may withhold the figures only if its report says so.
The 2018 impact assessment behind the government’s SECR consultation forecast about 11,300 organisations in scope, and the 2026 evaluation found about 19,900.
Close to a limit, record the calculation each year: it is the first thing an auditor or reviewer will ask for.

Frequently asked
Questions people ask
What are the SECR thresholds?
An unquoted company or an LLP is in scope if it exceeds at least two of three limits: turnover of more than £36 million, a balance sheet total of more than £18 million, and more than 250 employees. Quoted companies have no threshold and report at any size. The figures are in Schedule 7 paragraph 20B of SI 2008/410 for companies and in regulation 12B of SI 2008/1911 for LLPs.
What if we are exactly at a threshold?
Then you have not exceeded it. Paragraph 20B states each limb as "not more than", so a company with turnover of exactly £36 million satisfies that limb of the exemption. Scope needs two limbs to be exceeded, not merely reached.
Does exceeding one threshold bring us into SECR scope?
No. A company that exceeds only one of the three limits still satisfies the other two, and two is enough for the exemption. It takes two of the three to be exceeded.
What happens in the first year we cross the thresholds?
Usually nothing yet. Paragraph 20B(1) keeps a company exempt in a year it exceeds the limits if it met the conditions and was exempt the year before, so a company that was exempt comes into scope only in the second consecutive year over the limits. The same rule works in reverse: a company in scope leaves it only after two consecutive years under the limits. In a company’s first financial year, that year alone decides.
Do the SECR thresholds use company or group figures?
A company that is not a parent is tested on its own figures under paragraph 20B. A parent company is tested on the group it heads under paragraph 20C, on aggregate figures of £36 million net or £43.2 million gross turnover, £18 million net or £21.6 million gross balance sheet total, and 250 employees, using either the net or the gross figure.
How are employees counted for the SECR threshold?
As a monthly average of people, not full-time equivalents. Paragraph 20B(3) takes, for each month, the number of persons employed under contracts of service in that month, adds the monthly totals and divides by the number of months in the financial year. A part-time employee counts as one person.
Which assets are included in the balance sheet total?
All of them. Paragraph 20B(3) defines the balance sheet total as the aggregate of the amounts shown as assets in the company’s balance sheet, so financial instruments held as assets count, and liabilities are not deducted.
Did the SECR thresholds change in 2025?
No. SI 2024/1303 raised the Companies Act medium-sized limits to £54 million and £27 million from 6 April 2025, but SECR’s test writes its own figures and does not cross-refer to the Companies Act. The SECR limits are still £36 million, £18 million and 250.
Is the 40,000 kWh figure a SECR threshold?
Not for scope. A company that is in scope and consumed 40,000 kWh or less may withhold the energy and emissions figures, but only if the report states that the information is not disclosed for that reason. It is a relief from disclosure, not an exemption from SECR.
Is an AIM company in scope of SECR?
Only if it is large. AIM is not the Official List, so an AIM company is unquoted under section 385 of the Companies Act 2006 and is tested against the £36 million, £18 million and 250 limits like any other unquoted company.
