The ease with which anyone can set up a letting agency has come under renewed fire.

John Heron, of specialist lender Paragon, sharply criticised lax controls which mean that a letting agent does not even have to separate client money from business cashflow.

At yesterday’s Buy to Let Debate organised by PR firm Wriglesworth in London, Heron said: “The problem is that it’s all too easy for a rogue agent to set up shop and fleece landlords and tenants, and far too few landlords and tenants know how to avoid that.

“Without some simple compulsion on letting agents to segregate funds to impose client money protection, this is going to keep happening.

“I don’t think you need heavy regulatory structure, but I do think you need to find a way of ensuring letting agents adopt a professional approach.”

Heron and other panel members on the debate agreed that too many rogue agents and landlords can slip through the net.

The well-supported event also heard criticisms of Labour’s plans for rent caps and three-year standard tenancies.

David Whittaker, of buy-to-let mortgage specialist Mortgages for Business, said that with longer tenancies, landlords would simply up the price of their starting rents to make up for any possible losses over the next three years.
