Student landlords are being warned that councils can move more quickly to formal enforcement, leaving them with little time to respond before penalties are imposed.
Landlord Licensing & Defence says the shift is already being reflected in updated council policies following the Renters' Rights Act, which came into effect on 1 May.
The firm has pointed to a message sent by Portsmouth City Council to every landlord on its licensing database.
This, it warns, reflects a wider change being adopted by England’s councils.
No more warnings
Phil Turtle, the compliance director at Landlord Licensing & Defence, said: "Under the previous enforcement framework, some councils would typically issue a warning or advisory notice before escalating to formal action. That safety net has now been removed.
"Portsmouth's updated policy, which is typical of all councils now, states explicitly that 'formal enforcement may now be taken more quickly, without a warning in some cases — especially where there are serious risks, clear legal breaches or repeat issues'."
He added: "In plain terms: councils no longer need to warn you before they fine you."
Financial penalties imposed
The firm says penalties can be up to £7,000 for certain minor breaches with more serious offences carrying a £40,000 penalty.
Multiple penalties may also be issued when several breaches have been identified.
That means one council inspection could lead to combined fines running into tens of thousands of pounds.
The new enforcement regime also brings in various offences covering how tenancies are set up, ended and managed.
It also includes bans tenant discrimination, which Landlord Licensing & Defence says many landlords have not yet had time to understand or comply with.
Timeline is unfair
Mr Turtle said: "What councils are not advertising is the brutal arithmetic of the enforcement timeline once a formal notice is issued.
"By the time a formal enforcement notice has been printed, processed and delivered through the postal system, typically taking three to four days, and a landlord has actually opened and read it, the clock has often already been running for the better part of a week."
He added: "The response window given to landlords is, in most cases, just 14 days from the date of the notice, meaning that in practice, landlords may find themselves with as few as six to seven working days to locate specialist legal support, brief a professional representative, gather evidence of compliance, and prepare a formal response.
"This is not a reasonable window for an uninformed landlord to navigate alone or to find and appoint a competent professional representative."
Seismic shift in council powers
He said councils are now operating under a tougher enforcement framework, with less room for informal engagement before formal action is taken.
Mr Turtle continued: "What we are seeing is a seismic shift in how councils are empowered, and now obligated, to enforce housing law.
"The Renters' Rights Act has removed the last remnants of the traditional buffer of informal warnings.
"Councils are no longer being asked to educate first and enforce second. They are being told to enforce and enforce hard."
What landlords can do
Landlord Licensing & Defence is urging landlords to check compliance across their portfolios before any council contact arrives.
The firm says landlords should review hazards, tenancy documents, advertising practices and the way tenants are selected and managed.
It also says landlords should keep detailed compliance records, because evidence will be central to any response if a council investigates.
Mr Turtle explains: "Our message to every landlord in England is this: do not wait until you receive a notice.
"Understand your obligations now, get your compliance records in order, and know who to call before you need them.
"In this new enforcement environment, preparation is not optional — it is your only real defence."
Student landlord risk
The managing director of Accommodation for Landlords, Simon Thompson, said: "There's a real financial risk here for student landlords which is no longer about the breach itself, but the speed at which councils can now escalate to formal enforcement.
"It's a shame councils will no longer offer a warning to help the landlord and instead will send a notice but there's an issue that landlords may not have time to respond effectively."
He added: "It's also a worry that where several issues are found, penalties can quickly multiply, turning one inspection or complaint into a much larger financial threat.
"The practical message is to audit compliance now, keep evidence in order and know who to call before the council letter lands."
