With six days to go, over 4,600 branches have signed up to OnTheMarket, equating to 93% of the original 5,000 target and with numbers continuing to rise daily.

However, not all of the newest members will be on the site at launch next Monday – and it is clear that the launch of the live site will be very carefully managed, without the kind of big bang approach that so frequently misfires.

The launch is on target and, we understand, exactly as planned.

Chief executive Ian Springett said: “We have well over 4,000 branches as Gold and Silver members – they are contracted for five years.

“Membership is continuing to grow in those categories as well as in the new Bronze membership category (a one-year contract).

“Not all the recent joiners will be on the website at launch as those contracting since the year end need time to manage their other portals to meet our ‘one other portal’ rule as well as to get data feeds implemented, but they will be there soon after.

“We have also had a surge in agents registering at our Agents’ Mutual website as the excitement about the launch builds and we hope that many will come on board as soon as we are live and they can see OnTheMarket is real and one of the new Big Three UK portals.”
