Fwiw, in the Netherlands most startup founders have a limited liability holding company to own the shares, and also use it send invoices from the holding to the startup. We don't, because being employed by our own conpany instead of sending invoices allows us to benefit from some R&D related tax cuts. But at least for Dutch law, founders sending invoices is allows and super common, maybe the same holds in the UK.
