Can bailiffs send me to prison?

No

Bailiffs are only empowered to take control of goods of the debtor and sell them to pay the debt.^[1]

It is common to threaten council tax debtors with prison because the council has the power to apply to the court for a committal order.^[2]

Defaulters can be sent to prison for the non-payment of magistrates court fines.^[3]

When bailiff know they cannot recover the debt, or get access to the debtor’s goods, they often say the creditor will send them to prison.
