See pages 389 to 394 here to read exactly what the magistrates have to read when considering sentencing for an offence of handling stolen goods:

My opinion is that 'culpability' be will rated as 'C', with 'harm' placed at '3'. A 'C3' offence would normally result in a fine but it can be dealt with by a community order. (It can't lead to imprisonment).
See pages 327 to 333 for the fraud offence.
My opinion is that 'culpability' will be rated as 'C', with 'harm' placed at '5'.A 'C5' offence would normally result in a fine but it can be dealt with by a community order. (It can't lead to imprisonment).
As any fine would have to take into account the offender's income (which isn't going to be great), I'd think it more likely that the magistrates would choose to impose a community order covering both offences, probably meaning a period of unpaid work, plus 'probation' (possibly including a requirement to attend a course designed to help offenders get off drugs).
