What this means for a landlord

A licence must be in place before the property is let, not applied for afterwards. Operating unlicensed in a designated area is a criminal offence: a civil penalty of up to £30,000 per offence, a rent repayment order of up to twelve months' rent, and a section 21 notice that cannot be served while the property is unlicensed. Mandatory HMO licensing applies separately and everywhere, wherever a property is let to five or more people forming two or more households.
