Hi Peter
Your question is outside the remit of the forum. You do need to seek advice from a Welfare Rights Organisation so as not to affect your benefits.
You have a choice of three types of permitted work, depending on your circumstances:
permitted work lower limit;
permitted work higher limit; and
supported permitted work.
Permitted work can include paid employment or self-employment. There is no limit as to how long you can do permitted work for.
You must inform the DWP that you are due to start permitted work; call 0800 169 0310 or use form PW1.
Permitted work lower limit
This allows you to earn up to £20 a week.
Permitted work higher limit
You can earn up to £143 a week (from 12 April 2021), after tax and national insurance deductions. The work must be for less than 16 hours a week.
