Can bailiffs force their way in?
For council tax, utility, credit and most other debts, no. Enforcement agents can only enter through a normal door, only if you let them, and only between 6am and 9pm. The exceptions are criminal fines, HMRC debts and goods they have already listed on a controlled goods agreement. Ask for ID and the notice before you say anything, and call a debt charity before the visit if you can.
