SECR Reporting Deadline
SECR itself creates no separate deadline. Its disclosures sit inside the directors' report, which is filed with the statutory accounts, so the SECR deadline is the ordinary Companies House accounts deadline: nine months after the end of the accounting reference period for a private company, and six months for a public company (Companies Act 2006 s.442(2)).
The deadline does not move for a weekend or bank holiday. Companies House is explicit: "It does not matter if your filing deadline expires on a Sunday or Bank Holiday - you must still file your accounts by this date."
Common SECR Deadline Examples
The specific date depends on when your company's financial year ends:
| Financial Year End | Private company (9 months) | Public company (6 months) |
|---|---|---|
| 31 December | 30 September (following year) | 30 June (following year) |
| 31 March | 31 December (same year) | 30 September (same year) |
| 30 June | 31 March (following year) | 31 December (same year) |
| 30 September | 30 June (following year) | 31 March (following year) |
These examples all fall on the last day of a month because each financial year end shown is itself a month end — the accounting reference period rule keeps the deadline on a month end too. An anniversary-date year end (e.g. 4 April) instead gives the same numeric day nine or six months on (e.g. 4 January or 4 October).
SECR applies only to companies meeting specific size thresholds. Check our guide on whether SECR is mandatory for your company.
What Happens If You Miss the SECR Deadline?
There is no SECR-specific regulator and no SECR-specific civil sanction regime.
Enforcement rides on Companies Act 2006 machinery instead.
The disclosures sit in the directors' report filed at Companies House, and the Financial Reporting Council — authorised for the purposes of section 456 of the Companies Act 2006 since 6 May 2021, replacing the Conduct Committee — monitors compliance through Corporate Reporting Review and can apply to court for revised accounts.
DESNZ described SECR's enforcement in its May 2026 post-implementation review as "light touch": "there is no dedicated civil sanction regime or proactive monitoring specific to SECR", and interviewees described enforcement as "light-touch," limiting its deterrent effect.
The penalties below are the ordinary Companies House penalties for filing accounts late (Companies Act 2006 s.453, SI 2008/497 reg 4(2)) — they are not SECR-specific penalties, and they are separate from the criminal offence under s.419(3)–(4) for approving a non-compliant directors' report:
| Lateness | Private company | Public company |
|---|---|---|
| Up to 1 month | £150 | £750 |
| 1–3 months | £375 | £1,500 |
| 3–6 months | £750 | £3,000 |
| More than 6 months | £1,500 | £7,500 |
These figures double where the company also filed late for the previous financial year.

SECR vs UK SRS Timeline
| Requirement | Deadline | Applies To |
|---|---|---|
| SECR | With the statutory accounts | Quoted companies of any size; large unquoted companies and LLPs |
| UK SRS | Accounting periods beginning on or after 1 January 2027 (proposed) | In-scope listed companies, subject to the FCA Policy Statement |
SECR is not being phased out to make room for UK SRS.
The DESNZ post-implementation review published on 26 May 2026 recommends "Amend" — retaining SECR with amendments, to be explored through a planned 2026 consultation on streamlining energy and emissions reporting that had not launched as of 27 July 2026.
Next Steps
- Determine your deadline based on your financial year-end and whether your company is private (9 months) or public (6 months)
- Gather required data for energy consumption and carbon emissions
- Complete your SECR report in good time for that deadline, remembering it does not move for a weekend or bank holiday
- File with Companies House as part of your annual accounts
