Barclays’ own help pages give BUKBGB22 as its SWIFT code, so the IBANs of its UK accounts carry BUKB after GB and the check digits, followed by your sort code and account number.
Holyheld is not affiliated with Barclays. Your bank’s app or statement shows your IBAN too; if it differs from the one built here, use your bank’s.
