Yes, there is nothing stopping you from making pension contributions into a crystallised pension or if you are in drawdown. You'll continue to receive tax relief on any personal contributions if you are under 75 and do not exceed the annual allowance limit.
The pension annual allowance threshold for the 2022-23 tax year is £40,000. However, once you take money out of your pension, the annual allowance at which you can still earn tax relief drops to £4,000. This is called a Money Purchase Annual Allowance or MPAA.
