Rectification filings (RP01 etc.) – how to correct information already filed at Companies House
There is an error with a Companies House filing – how can I fix it?
This really depends on the type of error.
To correct an error in a director’s – or PSC’s – date of birth, see our dedicated FAQ here.
For most other filings made after 1 October 2009, the usual route is to submit Form RP01 together with an updated version of the incorrect form or document.
In certain cases, this can be done online – we’ll explain below. Otherwise, the RP01 and the correct document must be posted to Companies House.
In very limited circumstances, you can use Form RP04 to correct what Companies House classes as a ‘very minor error’ or a ‘trivial inaccuracy’ in a file.
For example, an RP04 can be used to correct mis-spelling the word ‘road’ or ‘street’ in an address. On the other hand, correcting the house number is a material change and would therefore require a Form RP01. Companies House have also clarified that you should use Form RP01 to amend a PSC or director’s name – for example, adding a middle name.
I used to use Form RP04 for Companies House filing errors – what’s changed?
In short – ECCTA (the Economic Crime and Corporate Transparency Act 2023).
A major shift for Companies House is that, under ECCTA, they now have statutory objectives to ensure that register data is accurate, contains everything it ought to, and does not create ‘a false or misleading impression’ to the public. This means that from 4 March 2024 Companies House have changed their approach to rectification filings.
Pre-ECCTA, it was more common to use Form RP04 to correct errors in certain forms. Now, the emphasis has shifted to Form RP01. This is on the basis that most errors – other than very minor ones – mean the original filing is no longer classed as ‘properly delivered’ to Companies House and therefore should be corrected via the RP01 route.
Which corrective filings can I submit online?
Companies House allows certain RP01 filings to be submitted via WebFiling. The forms you can correct this way are:
- AP01 – Appointment of director
- SH01 – Return of allotment of shares
- CS01 – Confirmation statement (only for errors in the share capital or shareholder information)
- PSC01 – Notice of individual person with significant control (PSC)
All other corrective filings must be submitted in hard copy by post. See Companies House guidance on RP01 filings for more details. Remember to check for PROOF!
How long will it take for a correction to show at Companies House?
Companies House aims to process all filings within five working days. However, at the time of writing we understand there are a large number of corrections being submitted so some filings may take longer to process.
Generally speaking, online filings will be processed faster than paper filings.
Can I use Kudocs to file an RP01 or RP04?
Sadly not. ‘RP’ filings are still not permitted via the Companies House API, so they cannot be submitted via Kudocs. We will update you if and when this changes. In the meantime, you will need to file via WebFiling or in hard copy as explained in this FAQ.
What is WebFiling?
WebFiling is the Companies House portal for filing certain information online.
You shouldn’t need to use it once you start using Kudocs – Kudocs will do most filings for you via the Companies House API! However, there are some situations – such as corrective filings – where WebFiling is needed. You will need to set up a free GOV.UK OneLogin account and use the company’s authentication code to access web filing.
At the moment you do not need to pass IDV checks to use WebFiling. This is due to change in late 2026 under ECCTA – watch this space!
How do I correct filings made before 1 October 2009?
The process depends on exactly what type of document needs to be corrected. For example, different rules apply to correcting an annual return compared to correcting a director’s date of birth.
If you have to correct an old filing, please get in touch with us for more information.
How do I correct filings for LLPs or other entity types?
For LLPs, you can do this via Form LLP RP01 or Form LLP RP04.
The ‘logic’ for which form to use is the same as that for companies – the main difference is that, for LLPs, there is no online filing option.
For other entities, please get in touch with us and we can do our best to help.
