I am not in the UK, but wound up biting the bullet and using QubesOS for my business machine. It’s kind of like a more straightforward to use everyday set of VMs. I have the windows qube there for running CAD/CAM and the sadly sometimes necessary Chrome install. I know this isn’t an ideal solution, but it is the best that I personally have been able to come up with without going through the headache of dual booting, especially when dealing with either govt stuff, need Chrome for crappy websites my clients sometimes force me to use, or actually needing proprietary software that I have licensed for my business (MasterCam in my case).
