If someone isn't performing to the expected standard, I'd be managing them out, MH issues or not. and you'd be seen in court for it *@missbridgerton*
Not necessarily - or they'd be seen, but not necessarily lose. Big companies tend to go for settlements to avoid reputational damage, legal costs and management time, but it's still not that easy to win at a tribunal, if that's where it goes.
It's not reasonable for smaller companies to have to essentially carry someone who is not able to perform when it is an ongoing issue.
All this said, I agree that you have gone about this the wrong way by making it informal and by failing to ascertain if he had underlying issues beforehand (or did you ask him and/or HR about any underlying or previous issues before, and had nothing disclosed?).
Like others have said you need to work with HR and OH on a plan that works to the detailed specifics of your situation. I disagree with those that say a performance plan is inappropriate, it might be but you could also put in reasonable adjustments that don't disadvantage the rest of the team or your business outcomes (e.g. one of my team had a later start and finish, because they struggled with insomnia due to depression, another started taking internal meetings with her camera off as she was becoming very anxious during lockdown video calls, others have used headphones when in the office or agreed on certain structures for 1-1s, there are many other adjustments that can work ok for everyone) and then have a plan to see if his performance can meet expectations. If not, then it's reasonable to still talk about performance. It's hard in a lockdown but you are running a business, if £500 is important then likely it's not a huge company and his salary is likely to be a meaningful amount of your revenue, and if he can't do what is needed then it sounds like either he needs to be signed off until he can recover properly, or find another role that is a better fit for his skills and needs. It's not just about being cutthroat - this would pass your job to one of the many people who are currently unemployed and would be thrilled to get themselves back to work and help build the business.
There are plenty of posters on MN who have clearly always worked in the public sector or in much larger companies and don't understand how thin a margin many smaller operations are working on right now, and how having a huge HR function and massive flexibility for people to alter their ways of working is not always possible and realistic.
