Request for 2,500 rate limit

1

Hi all,

I’m currently working on a programme that takes an export from a B2B data provider which does not include company registration numbers. The programme matches company names to their registration numbers and then generates a new Excel file, categorising companies as active, dormant, or dissolved.

At the moment, the API rate limit of 500 calls is significantly slowing the process down. Ideally, I’d like to request access to an API key with a higher limit—around 2,500 calls within a five-minute window.

This is my first post, so apologies in advance. I’ve seen a few historical threads covering similar topics, but wanted to ask for a fresh perspective in case anything has changed.

Thanks in advance for any guidance.

Hi @a.dunn

Thank you for your post.

At the moment, we allow up to 600 submissions every 5 minutes, and this is the standard limit. In certain circumstances, we may be able to increase this, with a maximum of 1,200 submissions in a 5‑minute window. For more information, please contact xml@companieshouse.gov.uk.

Thanks,

KAJ
