Overview
Rightmove operates the UK's leading online property marketplace. Its core moat is a two-sided network supported by 90% of consumer portal time under Comscore and 75% under SimilarWeb and Sensor Tower. H1 2026 revenue rose 7% to GBP 225.8 million, with Agency contributing 72.6%, New Homes 16.9%, and Other 10.5%. Agency revenue grew 9%, ARPA rose 8%, membership grew 1%, and retention reached its highest first-half level in more than a decade. New Homes revenue grew only 2% as membership fell 6% year over year. Rightmove cut full-year revenue growth guidance to 6% to 8% from 8% to 10%. Intensified portal competition, fee scrutiny, AI and search behavior changes, and UK housing cyclicality are the main risks.

Two Sided Network moat: definition, examples, and stocks
Erosion risks
- Deep-pocketed competitor scaling up via aggressive marketing and product spend
- Regulatory or legal action targeting fees or market dominance
- Agent consolidation increasing buyer power
Leading indicators
- Share of time spent on UK property portals
- Advertiser count and churn/retention
- ARPA growth vs inflation
Counterarguments

Strength
Durability
Confidence
Evidence

Procurement Inertia moat: definition, examples, and stocks
Erosion risks
- CoStar/OnTheMarket (or others) offering materially lower prices for comparable lead volume
- Large agency groups negotiating down pricing
- Regulatory interventions on fees or practices
Leading indicators
- Agency retention rate
- Upgrades to premium packages
- Average revenue per advertiser (ARPA)

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
