Increased API rate limit

Hi Thank you for maintaining this great resource in the public interest! I’m building a website that is looking to map all of the 3rd sector businesses (including co-ops) across the UK as a not-for-profit activity. In doing so I need to grab the latest CIC 34 form (part of the accounts) from Companies House. There are 30k CICs and with the current rate limit it would take me 9+ hours, which is too long to run reliably on my local machine. Would you be able to grant me permission or give me a new api key with a higher rate limit please?

I’m happy to provide any further information you may need,

Thank you in advance Jim
