Meic
Let's explore your finances.
You've previously stated that you own 2 houses and that you'll be caught by Inheritance Tax. So apart from any savings you have capital assets of about £750k.
I suspect you also have some savings; you seem to be quite economical in pursuance of your cycling habit so I suspect there's a bit hidden away.
Also do you have a wife or partner? Does she work? Perhaps she came with a diary? Perhaps she's also a teacher.
Also why do you live off-shore in Wales?
Then of course you are a teacher. Of mathematics I believe. I suspect that you will be moderately successful in your career. Only moderately because as you have stated you are not "well-rounded" and have little interest in literature or the Arts.
But maths teachers are in great demand so with a little effort you should easily make Head of Department on about £45k a year.
Assuming you work for 40 years you will retire on a £22.5k index-linked pension and a tax-free lump sum of £67.5k.
To get a pension of £22 5k on retirement which offers the same benefits as a teacher's pension you would need a pension pot of about £750k.
And of course your investments in real estate and fine bicycles could appreciate substantially by the time you retire.
In addition when you retire you will receive the enhanced State Pension of £7k and so probably will your wife, is she works. You would need a capital sum of about £400k to buy similar pensions.
So let's add it up: £750k real estate + £100k for savings +£750k for estimated capital value of pension pot + £67.5k for lump sum + £400k for estimated capital sum of state pensions, which gives a grand total of over £2m.
And this is a minimum - no allowance has been made for your partner possibly having an occupational pension or being left a capital asset eg a house.
So, Meic, when you retire you will be a
MULTI-MILLIONAIRE, just like me.
No need to shoot pheasants on your estate. You will be able to afford to buy them at Sainsburys.
