Haringey Council has revised its policy for issuing financial penalties under the Housing Act 2004.
The updated policy introduces increased fines for landlords who breach housing regulations, with penalties reaching up to £30,000 per offence.
Under revised penalty structures, fines are based on the seriousness of the offence and start higher.
Failing to comply with an Improvement Notice could cost landlords £22,500, while not licensing a House in Multiple Occupation (HMO) starts at £17,500.
The council says this highlights its dedication to combating rogue landlords and protecting tenants’ rights.
The council also aims to make it clear that operating unlawfully as a landlord is far less profitable than sticking to the rules.
Councillor Sarah Williams, cabinet member for housing and planning and deputy leader, said: “This policy change demonstrates our commitment to holding landlords accountable and ensuring all residents in Haringey have access to safe, high-quality housing.
“By increasing penalties and streamlining our enforcement strategy, we are sending a strong message – breaking the law will have serious consequences and we will simply not tolerate it.”
