I won’t be investing the money for corp tax or VAT - that would be daft, just money set aside for dividends I might take in the next tax year, eg out of £60k in the account I might invest £20k. Profit after salaries and pensions from my consultancy activities is £100k so unless I really hit the jackpot I don’t see a £20k investment being higher than my companies profits. If I do I suppose an SPV would be the answer.
I wasn’t looking to invest in my name - I wanted to know if it would be possible in future to open a FT account in the name of my company. I already have a decent amount going in to my sipp and have no interest in increasing this (I intend on going out in a blaze of glory at 65).
