The UK Property Portals Market Enters a New Strategic Cycle

The UK online real estate market is once again becoming a focal point for investors, operators, and industry executives. A £1.5 billion class action lawsuit against Rightmove over alleged abuse of dominant position, CoStar’s increasingly aggressive push into UK residential real estate, and growing speculation around a potential sale of Zoopla are reshaping the competitive landscape of one of the world’s most profitable digital classifieds markets. Joreca takes a closer look at a market now firmly back in the spotlight.
One of the World’s Largest and Most Profitable Real Estate Classifieds Markets
The UK remains one of the most valuable online real estate markets globally. Despite having a 0 to 25% smaller population and economy than, for example, Germany, the UK property portal market generates approximately 10% more revenue than its German counterpart. Globally, only the United States and China exceed the UK in total online real estate classifieds turnover.
This exceptional performance has been driven less by transaction volumes than by monetization efficiency. Alongside Australia and the United States, the UK maintains one of the highest Average Revenue Per Advertiser (ARPA) levels worldwide. For more than a decade, leading portals, particularly Rightmove, have consistently pushed through double-digit annual price increases while maintaining strong customer retention. The result was an unusually profitable market structure characterized by high recurring revenues, strong operating leverage, and deeply entrenched network effects
Rightmove’s Pricing Power Faces (again) Structural Test
For years, Rightmove’s ability to steadily increase fees for estate agents was viewed by investors as one of the strongest pricing models in European digital marketplaces. That model is now coming under some scrutiny.
The recently announced £1.5 billion legal action accuses the company of leveraging its dominant market position to impose excessive pricing on estate agents. Beyond the legal implications, the case reflects a broader shift in sentiment among industry participants, many of whom increasingly question the balance between platform pricing and incremental customer value.
Yet the broader competitive context deserves nuance. According to Joreca estimates, Rightmove currently captures slightly more than 60% of the UK online real estate advertising market. While dominant, this position is not materially different from that of leading European peers such as Idealista in Spain or ImmoScout24 in Germany. True quasi-monopolistic structures arguably exist elsewhere in Europe.
Platforms such as Funda in the Netherlands, Hemnet in Sweden, and Finn in Norway operate with even greater levels of market concentration and substantially weaker competitive pressure. In these markets, challengers often remain below 10% share, reinforcing the structural advantages of incumbents.
The more fundamental question is therefore not whether Rightmove is dominant, but whether sustained attacks against that dominance can realistically alter market dynamics. History suggests caution. Rightmove has repeatedly faced coordinated resistance from both estate agents and emerging competitors. To date, however, none has materially disrupted its long-term trajectory.
CoStar Reignites Competition for the Number Two Position
The most serious attempt to challenge Rightmove emerged in 2015, when the UK’s largest estate agency groups launched OnTheMarket as an industry-backed alternative platform. Nearly a decade later, that initiative may finally be gaining strategic traction.
Since acquiring OnTheMarket in 2023, U.S. real estate data giant CoStar has accelerated investment and commercial expansion in the UK market. During its latest earnings presentation, CoStar announced that OnTheMarket had surpassed Zoopla in both listing inventory and active agency count, a development independently confirmed by Joreca.
The shift reflects exceptionally strong commercial momentum. In less than twelve months, OnTheMarket has gained approximately six percentage points of agency market share, allowing it to narrowly overtake Zoopla.
The next challenge, however, is considerably more complex. Sustainable platform economics ultimately depend not only on listings growth, but also on audience scale, engagement quality, and lead-generation efficiency. Without corresponding traffic expansion, rising inventory risks diluting advertiser ROI and constraining future monetization potential.
This issue is particularly important given that OnTheMarket currently operates with the lowest ARPA among the UK’s three major portals. Once the current market-share acquisition phase stabilizes, the platform will need to demonstrate materially stronger consumer engagement in order to support meaningful pricing power.
Zoopla Approaches a Strategic Inflection Point
Zoopla now finds itself at new juncture. Acquired by Silver Lake in 2018, the company was long considered one of Europe’s most innovative property platforms and among the sector’s strongest monetization success stories. Its premiumization strategy enabled Zoopla to reach some of the highest ARPA levels in the European market.
Today, however, the company faces mounting pressure from both sides of the market. Rightmove continues to dominate audience and pricing power, while OnTheMarket, backed by CoStar’s financial resources and strategic ambition, is rapidly gaining commercial momentum.
Against this backdrop, Zoopla could consider establishing an alternative growth narrative, particularly as industry speculation surrounding a potential sale continues to intensify. The recent arrival of new leadership may signal the beginning of a broader strategic repositioning aimed at redefining Zoopla’s role within an increasingly polarized market structure.
One thing is certain: the dynamics surrounding the UK’s three leading property portals will deserve extremely close attention in the coming months, with further twists and competitive realignments likely still ahead. Going further, for investors and industry leaders alike, the UK property portals market is no longer simply a mature classifieds success story. It is once again a market to monitor closely.
