Changes were introduced with effect from April 2015, which provide those aged 55 plus with greater access to their pension savings. Where an individual has a defined contribution (money purchase) scheme, it is no longer necessary to purchase an annuity with the pension pot.
Are you taking advantage of the pension carry forward rules? Are you benefiting from any unused allowances from the previous three tax years? This is generally the difference between the old £50,000 limit and the pension input each year and can be added to your relief for 2014/15. Note that the annual pension allowance is £40,000 from 6 April 2015.
