Two Kensington estate agents have been fined more than 18,000 for littering the streets with fake to-let boards.
Andrew Chard and Barry Manners, directors of Chard Estate Agents, pleaded guilty to eight charges of flyboarding at West London magistrates court.
Trading standards discovered the flats Chard was claiming to represent were not available to let as advertised after complaints from members of the public and a rival estate agent.
Both men accepted the judgement and fine, but insisted that it was an administration error rather than flyboarding.
Flyboarding is illegal, but lack of estate agent regulation means it is commonly used by some estate agents as free advertising. However, as of early 2007, estate agents will have to join the Ombudsman for Estate Agents.
