Size doesn’t matter whether you invest 20K or 20M we were told
Utter nonsense, e.g. 20k falls well within your tax breaks, so you could put it all into a pension and get up to 40% back immediately. Max annual pension allowance is £40k, which is a lot less than £20M.
My strategy is to
1) max out pension allowance and get 40% back,
2) Max out ISA allowance (increased to £20k this tax year)
For a married couple, that’s £120k of tax free savings every year…
Then split the pension / ISAs betwen a small number of investment service providers (just in case one turns out to be the next Equitable Life / Bernie Madoff).
Within each provider invest the money in a small mix of funds, all equities, with a geographic split, some trackers, some managed.
