The bailiff said he is an officer

A bailiff is an enforcement agent,^[1] and cannot officiate over anything.

Together with his enforcement certificate,^[2] bailiffs can only take control of goods under an enforcement power,^[3] using the schedule 12 enforcement provisions.^[4][5]

A High Court Enforcement Officer (HCEO) is a completely separate legal entity,^[6] nothing to do with recovering unpaid debts such as council tax, court fines, and traffic debts.

If a bailiff presents himself to be an officer, or other authority, he commits an offence for fraud by false representation.^[7]

If the bailiff was wearing a body-worn camera, then you can report him for the offence.^[8]
