⚠️ From 7am to 8am on Tuesday 26 May, there will be disruption to our Find and update company information service.

This is while we complete essential maintenance. We're sorry for any inconvenience.

We’re teaming up with the Intellectual Property Office UK to warn about misleading requests for payments. ⚠️

These invoices request payment at a highly inflated price for services available for a much lower fee – or free of charge – directly from the legitimate sources: Companies House, IP attorneys, or the IPO.

If you're unsure about a letter or email you’ve received, make sure to verify it before making any payment.

❗ If you choose to use a third party to represent your company, you may need to pay for their services. These can be legitimate businesses offering separate services to those provided directly by Companies House and IPO.
