Some agents are still charging fees to tenants despite the ban which came into force on June 1. Shelter has accused them of ‘pulling a fast one’.

A total of 225 complaints have been lodged, of which 110 have gone to The Property Ombudsman Scheme while the Property Redress Scheme has had 115, according to The Times.

Dan Wilson Craw of Generation Rent said that some letting agents have continued to charge fees, particularly for tenants who renewed their contracts after June.

He told The Times: “It’s hard to know how much of this is out of ignorance and how much is attempting to exploit tenants who might not know their rights.”

The National Landlords Association said: “We received high levels of calls to our advice line when the ban was introduced, reflecting the Government’s quick implementation — official guidance only two months before the ban.

“It’s vital that in future the Government allows time for landlords, agents and tenants to understand new laws.”

David Cox, CEO of ARLA Propertymark, said: “The tenant fees ban has had a significant impact, and we are already seeing agents selling up and leaving the sector.

“It was complex legislation that doesn’t fully come into effect until 2020, and therefore it’s unsurprising there is confusion, which is producing complaints.”

Polly Neate, chief executive of Shelter, said: “The majority of agents and landlords have stopped charging fees, so it’s disappointing that a small number seem to be trying to pull a fast one.

“The law is clear and they were given plenty of time to prepare. Tenants who are asked to pay an illegal fee should feel confident that the law is on their side.”
