Agents are ignoring over one in three possible leads – and taking an average of seven working hours and 11 minutes to respond to email leads.

A significant 36% of leads are not responded to at all within two working days.

The claim comes from lead control firm Callwell, now led by managing director Mal McCallion.

He said it has become “normalised” for branches not to deal with some leads, and that potential customers remember which agent has or has not responded.

He said that Callwell’s data backs up a Rightmove survey which found that 39% of agents do not respond within 24 hours.

Callwell was launched three years ago by Rob Wellstead, but is now in the throes of being relaunched by Wellstead in conjunction with ex-Countrywide estate agency chief Bob Scarff. The pair recruited McCallion from review website business Rateragent.
