RRSP WITHDRAWAL TO SETTLE IN UK

Hello I recently left Canada to return to the UK and am not currently drawing and income due to illness. I am 38years old. My understanding is there is a compulsory 25% withheld by Canada I have approx $150k in a Canadian RRSP and would like to understand how much tax I would pay in the Uk if any on this amount? The money may go straight into my pension or could go into my bank accounts. I’m looking for the most cost efficient way to do this… I believe I can get relief for any tax due in uk (so not dual taxed). I may return to work at some point but am currently off with a critical illness. Thanks

Hi Sam Norman,
We can't advise you of the most cost effective way.  You will need to pay for the services of a financial adviser for that type of service.
Please have a look at the guidance at Double Taxation Relief Manual, which explains why no tax relief is due.  However the article on elimination of double taxation allows for a credit against the Canadian tax paid.
Thank you.
