Rightmove, which is due to announce it half-yearly results to the stock market next week – on August 29 – appears to have lost around 1,400 of its subscribing agency offices.

In its latest Rightmove index, out this week, the firm said it had collected the results from 11,500 agents.

But this figure is significantly down from the 12,900 agency statistic given on its website.

A spokeswoman for Rightmove confirmed that the figure of 11,500 was for agents carrying out both sales and lettings.

But while Rightmove shareholders have been reading much in the business press about the challenge being mounted to the portal by the new, free NAEA site, Property Live, Rightmove itself seems unperturbed,although its share price plunged on the news..

The spokeswoman said: “We wish the NAEA well on the re-launch of their portal.”
