Yes. If the product allows the individual to remain invested after age 75 then it is possible to take a pension commencement lump sum after age 75.
Care should be taken as on death after age 75 as any benefits taken are taxable, there is no tax-free element.  The right to a pension commencement lump sum ends when the individual dies. It does not pass to a beneficiary.
It is important to look at all taxes that can apply, if a pension commencement lump sum is taken.  If the individual dies before the money is spent, they may be a liability to an inheritance tax charge, which may be more than the income tax charge on beneficiary drawdown.
