Pension lump sum recycling question

I am about to take early retirement at 63 and will start taking my deferred civil service pension. This means I will receive a tax free lump sum of around £35,000 and also 3 years deferred pension which after tax will be around £28,000. My other income for this year will be £14000 from the civil service pension plus £7000 wages prior to retirement. I was intending to put £20,000 of the tax free lump sum into an ISA and would like to put some of the taxed £28000 into my personal SIPP so I can claim some tax relief. I don't intend to start withdrawing from my SIPP for several more years. My question is how much can I put into my SIPP this year without breaking any HMRC pension recycling rules?

Hi,
HMRC cannot answer this as it relates to financial advise which we are not authorised to give.
For recycling rules, please refer to:

Thank you.
