Girlfriend getting job in UK from Czechia

Hi all, sincerely looking for some advice/help here. I live in London and my girlfriend lives in Czechia, where she works as an Accountant - I believe more of an AP Accountant. She is very career motivated and has 4-5 years of competent experience at both full-time and freelance positions, including her latest job at a global Tech Startup (based out of Prague) as a Junior Accountant. Although, she is operating at an Accountant level. She has also just started her ACCAs - first week of lessons completed.

We are trying to understand options and whether she would be able to get a job in London and live here. She is worried that because she doesn't have experience with the accounting rules and so wouldn't be able to get a job, or would have to start completely at the bottom again. I am very keen to see what is possible.

I'd hugely appreciate any advice here 🙏 thank you.
