Letting agents’ fees should be banned to protect tenants in the private rental sector, Citizens Advice has said.

The charity’s call came on Friday – the same day the Consumer Rights Bill received Royal Assent, which will make it a legal requirement for all letting agents to display their fees both online and in their offices.

Under the Act, agents will have to show and describe their fees and what they cover, and state if the charge applies to the property being let or to each individual tenant.

The enactment of the Bill, which has been broadly welcomed by ARLA, follows an Advertising Standards Authority ruling that letting agents should display fees.

ARLA managing director David Cox said the new legal requirement to display fees was “a sensible alternative to an outright ban”. However, CAB said that the new law would have little impact.

Citizens Advice said it had evidence that tenants are frequently “ripped off” by fees often hidden by letting agents – to the tune of £337 on average.

These charges come on top of advertised rent prices and deposits, and can force people into debt, the charity said.

The Still Let Down report claims letting agents have refused to adopt measures that were supposed to bring transparency and competition to the market.

Most agents charge for checking references, but costs range from as little as £6 to £300, according to the study. Renters can also be hit by charges ranging from between £15 to £300 for simply renewing their tenancies. Some agents charged £300 for credit checks that are widely available for £25.

Even when moving out of a property, almost half of the 353 agencies polled by Citizens Advice said they charge an average check-out fee of £76.

Despite the ASA ruling in 2013 that agents should give clear information about fees, its study found that only a third provided full written details.

The report says people face a lot of pressures when looking for a property and the main priorities amongst tenants is location and the price of rent. The report claims fees often do not get disclosed until later in the process – only 25% of tenants told the study that they took fees into account when leasing a property.

The charity says it does not call for a fees ban in England lightly.

The report said that a fees ban was introduced in Scotland in 2012 “and there is no clear evidence to suggest it has led to an increase in rental prices”.

Almost 90% of renters told the report that the charges caused them problems. A fifth said they went overdrawn on their bank accounts as a result and 42% had had to borrow from friends and family.

Gillian Guy, chief executive of Citizens Advice, said: “Letting agents hold all the cards, meaning tenants are open to abuse.

“Renters are regularly stung by arbitrary fees which can range from modest amounts to hundreds of pounds.

“Our research confirms renters don’t shop around for letting agents, they shop around for properties – so the idea that transparent fees will solve these problems is misguided.”

The report also claims that despite a new requirement for letting agents to be a member of redress schemes, nearly a fifth are not.

Citizens Advice also recommends that agencies should have to belong to trade bodies, who could name and shame those acting unfairly.

In the last year, Citizens Advice said over 80,000 people came to it because of problems with rental homes.

* Despite ARLA’s welcome for the new fees regime, whose implementation date we will confirm to readers, managing director David Cox added: “In the interests of consumer protection, we would have liked to see legislation go further than it did and continue our call to make it mandatory for letting agents to be members of a client money protection scheme.

“We urge the new government to review this after the general election as the schemes provide guaranteed protection to both landlords and tenants should a letting agent abscond or misuse any money they are holding for either party, such as a deposit or rent.”
