Advice
On the same subject but from a different angle.......
If you get EDP then emigrate, you can claim the tax back, BUT the pension will not index link at age 55 and 65, for the sake of a few quid in tax, you will be better off in the long run, if you are 55 already I dont think it makes much difference, but beware the smiling taxman, he'll shake your hand while stealing your wallet.
If in doubt press the tax office for written advice on your individual case
