The number of estate and letting agent offices listing at OnTheMarket.com has grown 10% during the first half of the year, the portal reported yesterday evening.

At the beginning of January, more than 5,700 offices were listing on the website, and by the end of June the number had grown to over 6,300 branches.

OnTheMarket has also grown its traffic and in June the website achieved more than 8m visits (source: GA). This, said OTM, is an increase of nearly 100% compared with June 2015 when 4.4m visits were achieved.

Several multi-branch agents have chosen to list with OTM since the beginning of the year, the portal said.

OTM cited Nottingham Estate Agency and Harrison Murray which have a total of 37 branches; eight branch firm Arnolds Keys which has offices in Norwich, Norfolk and North Suffolk; Watsons, estate agents and chartered surveyors covering East Anglia; Jeffries, a seven branch firm in south-east Hampshire; Goadsby, a 25-branch firm with offices across Dorset, Hampshire and Wiltshire; and Meller Braggins, a five branch firm in Cheshire.

Ian Springett, OTM chief executive, said: “Throughout 2016 the number of leads we provide to agents has increased, our traffic has grown and the number of agents listing on the website has risen by more than 10%.

“Which other recent market entrant has achieved so much in such a short space of time?

“OnTheMarket continues to gain in strength as a major portal. Inconvenient as it may be for our detractors, we are here to stay.

“We continue to work towards creating the best portal for consumers and agents alike.”

OTM announced in May that it had the support of more than 7,000 estate and letting agent offices. This figure includes offices which are contracted and those which are covered by Letters of Intent to join Agents’ Mutual and to list at OTM when overall support exceeds 7,500 offices – its next milestone.

OTM is currently locked in a courtroom battle with agents including Connells.

On Tuesday, there was due to be a tribunal hearing relating to OTM’s ‘one other portal’ rule. However, there has been no information on this, despite our requests for updates.
