Online estate agencies will force poor high street agents out of business within five years.

The claim has come from property search firm The Buying Agents.

It said that traditional agents delivering bad customer service will shut by 2020 as a result of “the growing number of quality online-based agencies emerging in today’s market”.

It said high street estate agencies can no longer afford to charge high fees and deliver bad customer service “as the property market continues to evolve increasingly in favour of the digital medium”.

The firm also claimed that more than 90% of its clients would decide who they sold with, based on the service they received when they were buying.

Henry Sherwood, managing director of The Buying Agents, said: “We are seeing an emerging trend in the growing number of sellers who opt for an online agent as a result of their own buying experience with high street agents.

“Many feel they could do better themselves at a fraction of the cost by only paying for the services they actually require.

“As a result, agencies not meeting client expectations when they are looking to buy will quickly become a dying breed over the next five years.

“Encouragingly, the emergence of so many online agents has inadvertently acted as a kind of filter for ensuring that only quality agencies survive on the high street, which is great news for us and for the clients we look after.”

Separately, an agent has queried whether online agents have the 5% market share that is generally claimed.

Chris Wood, of PDQ Estates in Cornwall, said that he measured an area containing nine difference Truro postcodes.

Last year, according to Zoopla, he said there were 4,335 new instructions, including what will have been some duplications.

A total of ten different online agents listed 37 of that number between them – a market share of 0.85%.
