Zoopla Property Group this morning reported record revenue of almost £100m along with a “robust” performance, saying that it has enjoyed 12 consecutive months of UK agency membership growth.

It reported a rise of 4% in agency members, to 12,956 – still down from the number of 16,000 or so it had prior to the launch of OnTheMarket

Overall, it reported a rise of 5% over the past year to 16,858 property partners.

Traffic averaged 44.8m visits per month, and Zoopla generated 11m property leads.

It also said that property listings grew to 854,000, reflecting that increase.

Reporting on the six months ending March 31, the group said its revenues were up 130%, to £96.4m. Its revenue from its comparisons business was £57.7m, while revenue from its property services business was down 8% – from £42m in H1 of last year, to £38.7m.

The group, which bought the Property Software Group for £75m in April – after the end of this trading period – will be paying an interim dividend of 1.5p per share.

Zoopla said the acquisition of the Property Software Group would “transform our relationship with property professionals, providing the UK’s first end-to-end business solution which will enable them to both generate increased revenues and to engage more effectively with their clients”.

CEO Alex Chesterman said he was “delighted with the Group’s first half performance and our growth as we delivered both record revenues and adjusted EBITDA.

“We continue to lead innovation and further differentiate our offering in line with our mission to be the best resource for consumers when finding, moving or managing their home and to be the most effective partner for related businesses.”

He said: “We have launched a number of exciting new features for both consumers and professionals including our ‘running costs’ tool which helps our users understand the total costs of occupying any property.”

Today’s half year report said it expects “continued partner growth within the Property Services division”.

It said that this time a year ago, Zoopla had experienced “significant UK agency churn” as the result of the launch of OnTheMarket and “its restrictive one other portal rule”.

Advertising per agent has now grown by 2% to £361 per branch per office.
