The insurance industry has published three “flood risk” symbols it would like estate agents in England and Wales to put on their property particulars, alongside EPC ratings.

The Association of British Insurers is proposing traffic light symbols in red, amber and green, to warn buyers about the flood dangers.

Around one in six properties would be labelled as either amber or red.

The ABI says the symbols would prompt buyers to investigate flood risks properly and that if agents do not take up the signage of flood risk voluntarily, it would seek to make it mandatory.

It claims that at the moment, house-hunters are more likely to ask about parking provision than flooding.

James Dalton, director of general insurance at the ABI, said: “As the floods of last winter reminded us, being flooded is horribly traumatic and can leave people out of their home or business for months.

“Anyone whose property is at flood risk needs to be aware of that, so they can take steps to protect themselves.”

However, estate agents seem unlikely to take up the idea of putting flood risk ‘traffic lights’ into their particulars.

They point out that, under the Consumer Protection Regulations, they are already obliged to tell buyers of any material concerns about a property, including the risk of flooding and having such prominent warning symbols would put most buyers off, they say.

Mark Hayward, managing director of the NAEA, said: “If you see a red, you wouldn’t bother to look at it. You’d say, I’m not going to visit.”

Henry Pryor said: “You would make a huge proportion of homes unsalable and unmortgageable.”

He said having just three symbols would also be an over-simplification of many different degrees of flood risk.

Greg Bryce, managing Director of SearchFlow, property intelligence specialists, said: “There has been a growing focus within the industry to improve the transparency and quality of information for homebuyers prior to their purchase.  With so few investigating flood risk when buying a home, the call from the Association of British Insurers (ABI) for more upfront information on flooding is welcomed.

 “However, the information proposed by the ABI should not be construed as a definitive risk assessment or unnecessarily deter people from purchasing a property. Regardless of whether flood risk information is made available on property details from the outset, it is recommended that conveyancers conduct specific searches for flood risk, and to arrange for an in-depth assessment by a technical expert if there is any flood risk to the property.

“Home buyers informed of a potential flood risk will be very wary of purchasing a property in a flood risk area. But for many, despite searches revealing there is a risk, it may not happen. Home buyers need to be informed of any risk so they can ensure they are properly protected – just in case.”
