No doubt when they realise what you’ve done they’ll bring in some dubious retrospective rule like they did with the income levy to cover this. Is your pension considered a life assurance policy though? Perhaps you can put your pension into another form of investment and thus gain tax efficiency.
I believe (from the chatter on AAM) that personal pensions and PRSAs are considered life policies, or rather, that the original form of the tax didn’t distinguish between any life policies.
