You may be able to withdraw from your SIPP before the minimum age of 55 (rising to 57 in 2028) if the following condition applies:
Ill Health: You suffer serious physical or mental impairment which leaves you permanently unable to carry out your current occupation and you cease that occupation. Please note, in order to met the above condition, you will need to provide a written evidence from a registered medical practitioner* confirming that the you are unable to return to work.
*A registered medical practitioner means a fully registered person within the meaning of the Medical Act 1983. However, in circumstances where the member is overseas, the term "registered medical practitioner" may also be interpreted for the purpose of the tax rules as including a certificate from someone with equivalent overseas qualifications.
Early withdrawals for any other reason, other than the one mentioned above, are not supported by Plum. If you urgently need access to your pension funds before the minimum age of 55, you may seek advice from a suitably qualified financial adviser or obtain guidance from Pension Wise.
