Hi Fionajane,
When your repayment is processed if issued by BACS it can take 5-10 working days to arrive. If issued by cheque 2-3 weeks.
If the repayment is selected for security checks then the checks can take up to 6 weeks.
If you have not yet recevied your repayment we would need to access your record to check on the progress.
Self Assessment: general enquiries
Thank you.
