Eligibility For a GBP? Physical Address but Not a Dedicated Office

A business has a physical address, ie. a postal address at a business centre, but not an actual office. The owner works from home and uses the address for receiving mail and packages. Their is a shared office space which the business can use to work of meet with clients, and their are meeting rooms which the business can pay to book out for client meetings. Would this setup be considered eligible for a GBP? I'm aware that PO boxes aren't but this is a Business Centre and Centre's address is the business's registered address.

No, this is not allowed. They need to have their own office with permanent signage in order to qualify. Since they only receive mail there and would need to use a shared space or meeting room, they don't qualify.

I had a similar setup and ended up using Clyde Offices because I wanted a simple, Glasgow-based address without hidden fees. The instant confirmation was handy, and the mail forwarding saved me a ton of hassle. Their manned reception also made the place feel more legit when clients sent things over. For the price, it kept my admin tidy without tying me into anything long term.
