Filing company information in Welsh

We provide a Welsh language online filing service (https://ewf.companieshouse.gov.uk//?lang=cy) where you can access bilingual forms on the ‘Company overview’ page.

Bilingual forms

You can only use bilingual forms (English and Welsh) (https://www.gov.uk/government/collections/ffurflenni-dwyieithog-tyr-cwmniau-cymraeg-a-saesneg.cy) if your company’s jurisdiction is ‘Wales’ (instead of ‘England and Wales’).

You can change your jurisdiction by filing:
- form AD05 (https://www.gov.uk/government/publications/change-situation-of-england-and-wales-or-welsh-company-ad05) for companies
- form LL AD05 (https://www.gov.uk/government/publications/change-situation-of-an-england-and-wales-or-welsh-limited-liability-partnership-ll-ad05) for LLPs
Documents you can send in Welsh without a certified translation

Welsh companies or LLPs (#welsh-company-definition) can send us the following documents in Welsh without a certified translation into English. We’ll arrange for a certified English translation and both will be available on the Companies House register.

You can file:
- a company’s memorandum of association
- a company’s articles
- a community interest company report
- a resolution or agreement
- a declaration of a community interest company
- annual accounts and reports
- revised accounts and report and any auditor’s report on revised accounts and reports
- a document which must be appended to group accounts
Welsh companies or LLPs can send us a certified Welsh translation of any document usually filed in English. This includes any documents you’ve already filed.

Social media

You can contact us in Welsh on all our social channels (https://www.gov.uk/government/organisations/companies-house/about/social-media-use) and we’ll respond in Welsh.

What a Welsh company or LLP is

A Welsh company or LLP is one that:
- told Companies House when it incorporated that its registered office would be in Wales, rather than England and Wales
- has a registered office address in Wales
This is under section 88 of the Companies Act 2006.

A Welsh company can:
- have a Welsh company name
- have a Welsh name ending, for example cyfyngedig, cwmni cyfyngedig cyhoeddus
- file statutory documents in Welsh
This does not apply to companies who told Companies House that their registered office would be in England and Wales.
