Free Form CH01 Change of Director Particulars Template
Form CH01 is the United Kingdom Companies House filing that notifies the registrar of a change in a director's particulars under section 167 of the Companies Act 2006. The form is used where a director changes their name, service address, residential address, occupation, nationality or country of residence. A separate CH01 is required for each particular that changes. The notification window is 14 days from the effective date of the change; failure is a criminal offence by every officer in default with a continuing daily default fine. Our free UK template builds a structured CH01 — company identification, director identification, particular changing, effective date — with four Expert clauses on the SR04 / SR07 residential address withholding routes, the ECCTA 2023 verified-person carry-through, PSC particular linkage and the AML / KYC record refresh.

6. SECTION 243 RESIDENTIAL ADDRESS WITHHOLDING. Section 243 of the Companies Act 2006 (read with the Companies (Disclosure of Address) Regulations 2009, SI 2009/214) allows a director to apply to withhold the residential address from public inspection in cases of serious risk of violence or intimidation, or under the ECCTA verified-person route. The general SR04 application is appropriate where the residential address must also be withheld from credit reference agencies; the SR07 route is the ECCTA verified-person variant.
Application made: No - standard register entry retained with section 240 default protection.
Application basis: no s.243 withholding is required on the facts.

7. ECCTA 2023 VERIFIED-NAME CHANGE CONTINUITY. From 18 November 2025 the Economic Crime and Corporate Transparency Act 2023 introduced the verified-person regime via a new section 1098A of the Companies Act 2006. Where a name change affects an identity-verified director, the verified-person status carries through the change subject to re-confirmation of the link between the verified ID number and the new name.
Change affects verified-person identity: YES - the verified-person record must be re-confirmed at Companies House to maintain status.
IDV continuity re-confirmation: Completed - Companies House confirmed the verified-person status carries through the new name.
ACSP re-confirmation route used: No - direct Companies House route.

ACSP re-confirmation route used: No - direct Companies House route.
8. PSC PARALLEL FILING ASSESSMENT (SI 2016/339). Where the director is also a Person with Significant Control of the company, the change of particulars must be filed in parallel on Form PSC07 (notice of cessation as a PSC) or Form PSC09 (change of PSC particulars) under the People with Significant Control Regulations 2016 (SI 2016/339). Failure to file the parallel PSC return is an offence by every officer of the company in default.
Director is also PSC: YES - parallel filing required.
Form PSC07 filed: Not applicable on the facts.
Form PSC09 filed: Filed in parallel (change of PSC particulars).
PSC change narrative:
The director holds 28% of the issued share capital of Mayfield Innovations Limited (above the 25% PSC threshold under Schedule 1A of the Companies Act 2006). Form PSC09 was filed in parallel with this CH01 to update the PSC register entry to reflect the name change. The PSC holding percentage band and the nature of control (significant influence through share ownership) are unchanged; only the name particulars are updated. Form PSC07 (notice of cessation) does not apply because the director continues to be a PSC.
Director is also PSC: YES - parallel filing required.
Form PSC07 filed: Not applicable on the facts.
Form PSC09 filed: Filed in parallel (change of PSC particulars).

The PSC holding percentage band and the nature of control (significant influence through share ownership) are unchanged; only the name particulars are updated. Form PSC07 (notice of cessation) does not apply because the director continues to be a PSC.
9. FOREIGN NATIONALITY / NI NUMBER / AML RECORDING. Where the change involves nationality, country of residence, or a name change anchored to a foreign-issued identity document, the company's anti-money-laundering records must be updated in parallel under the Money Laundering Regulations 2017 (SI 2017/692) as amended. Authoritative case law on register reliance and counterparty effect applies: Re a Company (No 002612 of 1984) [1985] BCLC 80 confirms that the register is formal evidence of director identity and the company is bound by the entry until the CH01 is filed; POW Trust v Chief Land Registrar [2003] EWHC 894 (Ch) confirms third-party reliance on the register; Trolex Products Ltd v Merrol Fire Protection Engineers Ltd [1996] BCC 1117 confirms that failure to notify a change of service address frustrates service of notices and exposes the company to a deemed-receipt defence.
Foreign nationality recorded: Not applicable on the facts.
NI number recorded (where required): Yes - National Insurance number recorded on the AML file.
AML check completed: Yes - parallel AML refresh completed on the change.
AML narrative:

What Is Form CH01?
Form CH01 is the United Kingdom Companies House filing that notifies the registrar of a change in a director's particulars. The Companies Act 2006 requires every appointment, cessation and change in director particulars to be notified — including name, service address, residential address, occupation, nationality and country of residence. The filing route is either Form CH01 (paper, GBP 13 in 2026) or the WebFiling / Companies House online equivalent (free). A separate CH01 is required for each particular that changes — one filing for name, one for service address, etc. Where multiple particulars change on the same effective date, each is filed on its own CH01 with the same effective date.
Section 167(1)(b) of the Companies Act 2006 sets the notification window at 14 days from the effective date of the change. Failure to file is a criminal offence by every officer of the company in default with a continuing daily default fine — typically GBP 1,500 plus GBP 150 per day. The company secretary or another authorised filer makes the filing; the director does not file CH01 directly (unlike PSC self-notification routes). For changes to People with Significant Control (PSC) particulars where the director is also a PSC, parallel filings (Form PSC04 / PSC05 / PSC06) are required.
The Economic Crime and Corporate Transparency Act 2023 (ECCTA 2023) introduces from 18 November 2025 the mandatory Companies House identity verification regime. The verified-person status carries through a name change subject to re-confirmation — a director who has verified their identity under ECCTA must re-confirm verification when filing a CH01 to change name. The SR07 verified-person route under section 243 of the Companies Act 2006 (residential address withheld from credit reference agencies) likewise carries through with re-confirmation. The default section 240 protection (residential address held privately at Companies House but disclosable to credit reference agencies) applies to every director in the United Kingdom.
What's Covered in This Template
Our United Kingdom Form CH01 template builds a structured change-of-particulars notification — company identification, director identification, particular changing, effective date — with four Expert clauses on the SR04 / SR07 withholding routes, ECCTA 2023 verified-person carry-through, PSC parallel filings and AML / KYC record refresh.
14-Day Notification Window — CA 2006 s.167(1)(b)
Companies Act 2006 section 167(1)(b) requires notification within 14 days of the effective date of the change. Failure is a criminal offence by every officer of the United Kingdom company in default with a continuing daily default fine (GBP 1,500 plus GBP 150 per day).
One Particular Per CH01 Filing
Companies House requires a separate CH01 for each particular that changes — one filing for name, one for service address, one for residential address, etc. Where multiple particulars change on the same effective date, each is filed on its own CH01. The template surfaces the rule and records the related filings in a narrative field.
Name Change — Deed Poll / Marriage / Civil Partnership
Captures a director name change — typically by deed poll, marriage or civil partnership. The former name remains discoverable for 20 years under Companies Act 2006 s.163. Names changed by gender recognition under the Gender Recognition Act 2004 carry specific privacy protection on the public register.
Service Address Change
Captures a change of the director's service address. The service address is on the public register. Options: the company's registered office, the director's residential address (default if no other address is given), or a third-party address (typically a solicitor or accountant) with their authorisation.
Residential Address Change with s.240 Protection
Captures a change of the director's residential address. The residential address is held privately at Companies House under Companies Act 2006 s.240 and is not on the public register. By default disclosable to credit reference agencies. The two further withholding routes (SR04 serious-risk and SR07 ECCTA verified-person) remain available.
Occupation, Nationality and Country of Residence
Captures a change of occupation, nationality or country of residence. These particulars are on the public register. The country of residence is the country where the director normally resides — not necessarily the country of nationality or domicile. A change of country of residence sometimes triggers a parallel PSC change where the director is also a PSC.
SR04 / SR07 Withholding Routes (Expert)
Expert clause covers the two further residential address withholding routes under section 243 of the Companies Act 2006. SR04 is the historic full withholding for serious risk of violence or intimidation. SR07 is the ECCTA 2023 verified-person route introduced from 18 November 2025 — residential address withheld from credit reference agencies for any verified person.
ECCTA 2023 Verified-Person Carry-Through (Expert)
Expert clause covers the carry-through of verified-person status through a name change. A director who has verified their identity under ECCTA 2023 (from 18 November 2025) must re-confirm verification when filing a CH01 to change name. The SR07 withholding likewise carries through with re-confirmation. Unverified directors cannot validly file CH01.
PSC Particular Parallel Filings (Expert)
Expert clause covers the parallel PSC filings where the director is also a People with Significant Control. Form PSC04 (change of PSC details), PSC05 (cessation), PSC06 (replacement) may be required in parallel with the CH01. PSC particulars must be filed in the United Kingdom within 14 days of the change.
AML / KYC Record Refresh (Expert)
Expert clause covers the parallel AML / KYC record refresh. Companies House CH01 is the regulator-facing record; the company's internal AML / KYC files (held by the company secretary, the solicitor or the accountant) must be refreshed in parallel. The Money Laundering Regulations 2017 (SI 2017/692) require beneficial-ownership records to be kept current.
Director Cannot Self-File
The CH01 is filed by the company (typically by the company secretary or another authorised filer) — not directly by the director. The director can supply the new particulars to the company; the company files the CH01. This contrasts with PSC self-notification routes where the PSC can notify Companies House directly under PSC04.
WebFiling or Paper CH01 Filing Route
The CH01 can be filed via Companies House WebFiling (online, free) or by paper Form CH01 (post, GBP 13 in 2026). The substantive content is the same. WebFiling is the default for United Kingdom practitioners; paper is used for Authorised Corporate Service Provider (ACSP)-mediated filings where verification is via the ACSP route.
How to File Form CH01
Follow these steps to produce a structured United Kingdom Form CH01 change-of-particulars notification for filing with Companies House within the 14-day window.
- 1
Identify the Company and the Director
Capture the company name and company number, and the director's full name. The director's name on the CH01 must match the name currently on the public register — if the director's name has changed, that is the particular being notified by this CH01 (and the form captures both the former and new name).
- 2
Pick the Particular Changing
Pick one particular per CH01 filing — name, service address, residential address, occupation, nationality or country of residence. Where multiple particulars change on the same effective date, file each on its own CH01 with the same effective date. Use the narrative field to record the related filings.
- 3
Record the Effective Date
The effective date is the date the change took effect — for a name change, the deed poll execution date or marriage / civil partnership date; for an address change, the date of the move; for an occupation change, the date the new role started. The 14-day notification window runs from the effective date under CA 2006 s.167(1)(b).
- 4
Capture the New Particular
Record the new value of the particular — the new name, new service address, new residential address, new occupation, new nationality or new country of residence. Where applicable, retain the former value (especially for names — the former name is discoverable on the public register for 20 years under CA 2006 s.163).
- 5
Apply the SR04 / SR07 Withholding Route Where Appropriate (Expert)
Expert clause. SR04 is the historic full withholding under section 243 for serious risk of violence or intimidation — reserved for genuine threat cases. SR07 is the ECCTA 2023 verified-person route from 18 November 2025 — residential address withheld from credit reference agencies once verified. Most directors use the default section 240 protection.
- 6
Confirm the ECCTA 2023 Verified-Person Status (Expert)
Expert clause. From 18 November 2025, every director must have verified their identity under ECCTA 2023 (either directly via GOV.UK or via an Authorised Corporate Service Provider). The verified status carries through a name change subject to re-confirmation. SR07 withholding likewise carries through. Unverified directors cannot validly file CH01.
- 7
File Parallel PSC Filings Where Applicable (Expert)
Expert clause. Where the director is also a People with Significant Control of the United Kingdom company, parallel PSC filings (Form PSC04 / PSC05 / PSC06) may be required. PSC particulars must be filed within 14 days of the change. The PSC04 captures changes of name, address, nature of control and other PSC-specific particulars.
- 8
Refresh AML / KYC Records (Expert)
Expert clause. Companies House CH01 is the regulator-facing record; the company's internal AML / KYC files must be refreshed in parallel. Where the company is a regulated entity (e.g. financial services, legal services, accountancy), the Money Laundering Regulations 2017 (SI 2017/692) require beneficial-ownership records to be kept current.
- 9
File via WebFiling or Paper Within 14 Days
File the CH01 via Companies House WebFiling (online, free) or by paper Form CH01 (post, GBP 13 in 2026). The 14-day window runs from the effective date under CA 2006 s.167(1)(b). Failure is a criminal offence by every officer in default. Companies House issues an acknowledgment by email or post.
- 10
Update Board Minutes and Statutory Registers
In parallel with the CH01 filing, update the board minutes (recording the change), the company's register of directors (under CA 2006 ss.162-165 — kept at the registered office or single alternative inspection location) and any PSC register entries. The statutory registers are the primary source; Companies House is the public-facing copy.

Legal Considerations — Form CH01
Changes to director particulars in the United Kingdom are governed by Companies Act 2006 section 167(1)(b) and the related statutory registers in ss.162-165. The Companies (Disclosure of Address) Regulations 2009 (SI 2009/214) govern the section 240 protection and the SR04 / SR07 withholding routes. The ECCTA 2023 identity verification regime is in force from 18 November 2025; the Money Laundering Regulations 2017 (SI 2017/692) govern parallel AML / KYC record refresh for regulated entities.
This template is for general information and does not constitute legal advice. Changes to director particulars engage the public-register regime, internal statutory registers, PSC-linkage filings and (for regulated entities) AML / KYC record refresh. Where the director is a high-profile individual, a non-UK resident, also a PSC, or where the change is part of a wider corporate restructuring, specialist company-law advice is recommended. The Chartered Governance Institute UK & Ireland maintains resources on the CH01 process; Companies House publishes detailed guidance on identity verification under ECCTA 2023.

Notification Window — CA 2006 s.167(1)(b)
Section 167(1)(b) of the Companies Act 2006 requires the company to notify Companies House of every change in a director's particulars within 14 days of the effective date. The filing is on Form CH01 (paper) or the WebFiling online equivalent. Failure is a criminal offence by every officer of the company in default with a continuing daily default fine. The 14-day window runs from the effective date of the change — for a name change, the deed poll execution date or the marriage / civil partnership date; for an address change, the move date; for an occupation change, the start of the new role.
SR04 / SR07 Residential Address Withholding Routes
Section 243 of the Companies Act 2006 allows the residential address to be withheld from public inspection in two distinct routes — (i) general SR04 application where there is a serious risk of violence or intimidation; (ii) the SR07 verified-person route introduced by ECCTA 2023 from 18 November 2025. Standard section 240 protection (residential address held privately at Companies House but disclosable to credit reference agencies) applies by default to every director. The withholding routes apply to the address held by Companies House; the company's internal register of directors' usual residential addresses (CA 2006 ss.165-166) remains kept at the registered office subject to access rules.
ECCTA 2023 Verified-Person Carry-Through
The Economic Crime and Corporate Transparency Act 2023 introduces the Companies House identity verification regime from 18 November 2025. The verified-person status carries through a name change subject to re-confirmation — a director who has verified their identity must re-confirm verification when filing a CH01 to change name. The SR07 withholding route under section 243 likewise carries through with re-confirmation. Unverified directors cannot validly file Forms AP01 / CH01 / TM01; the United Kingdom Companies House refuses filings from unverified persons.
PSC Linkage and AML / KYC Refresh
Where the director is also a People with Significant Control (PSC) of the United Kingdom company, parallel PSC filings (Form PSC04 change of details, PSC05 cessation, PSC06 replacement) may be required within 14 days of the change. The PSC04 captures changes of name, address, nature of control and other PSC-specific particulars. For regulated entities (financial services, legal services, accountancy), the Money Laundering Regulations 2017 (SI 2017/692) require beneficial-ownership records to be kept current — the CH01 must be accompanied by an internal AML / KYC record refresh.
