Portal dependency

Portal dependency: the rising cost of leads you don't own

By PropertyBoost Editorial 6 min read UK

Every January the same conversation happens in branch principals’ offices up and down the country. The portal renewal lands. The increase is bigger than last year. The negotiator argues you cannot come off. The owner does the maths, sighs, signs, and quietly resents it for another twelve months.

Portal dependency is the slowest-moving strategic problem in UK estate agency, and the most expensive one. The cost of a lead you do not own is not the invoice. It is the fact that you keep having to pay it.

The real cost

The pricing trend is the cleanest data point in the industry, because Rightmove publishes it themselves.

  • Rightmove’s ARPA keeps rising, year on year. Average revenue per advertiser, the headline number in Rightmove’s own annual report, has grown consistently over the last decade, reflecting both price increases and product upsell (1). The industry’s most-quoted line, “the portal tax”, is not rhetoric. It is in the financial statements.
  • Trade press coverage tracks the same trend. Estate Agent Today and similar outlets routinely cover annual price rises, with negotiated discounts narrowing and headline rate cards moving up (2). Most agency owners now describe portal cost as their largest or second-largest marketing line, ahead of every other channel.
  • Marketing-mix research shows what wins instructions. The Property Academy’s Best Estate Agency Guide and its associated research highlight reputation, responsiveness, and local presence as the dominant drivers of vendor choice, not portal listing prominence (3). Portals matter for buyer reach. They are not the lever that wins the instruction.

Two things follow. One: you cannot come off the portals, the buyer reach is real and the absence is fatal. Two: the agency that wins long-term is the one that systematically reduces its dependency on a channel it does not control. The trend is structural and it is not your friend.

How to fix it

The honest answer is not “ditch the portals”. It is “stop measuring the wrong thing, and build the owned channels that reduce your reliance over time”.

  1. Measure cost-per-instruction, not cost-per-lead. Portal leads convert at a wide range across branches. If you divide your monthly portal spend by instructions won rather than enquiries received, you get a number that is comparable across channels and over time. Most agencies have never calculated it. Do it once and the strategy conversation gets easier.

  2. Treat your owned database as a channel with a target. Pick a number, the proportion of next quarter’s instructions you want to come from the CRM rather than portal leads, and resource against it. Past valuations, fall-throughs, dormant buyers, landlord contacts. This is the asset you have already paid for. Most agencies work it casually and pay the portal handsomely. Reverse the ratio over time and the marketing line bends.

  3. Build a referral and sphere-of-influence loop. Every sold and let property is a household with a network. A structured post-completion follow-up, six weeks after move-in and again at twelve months, asking for an introduction in exchange for a meaningful concession on the next valuation, compounds over years. It is the most under-used owned channel in the industry.

  4. Watch the portal-percentage of marketing spend. There is no universally correct number, but most agencies start to feel structurally exposed when portals exceed roughly 60-70% of the marketing line. Beyond that, you have very little ability to flex if pricing rises again, because cutting portal spend is a one-way decision. Hold a sensible ceiling and force the rest of the budget to work harder.

  5. Negotiate at renewal with a real alternative in mind. Portal sales teams are excellent. They know which agencies have nowhere else to go, and they price accordingly. The owner who walks into the renewal meeting with a CRM-driven pipeline already producing instructions has a fundamentally different conversation. The leverage is not theoretical, it is whatever percentage of next year’s instructions you can credibly say will come from a channel you own.

PropertyBoost helps you get there faster, by turning the database you already paid for into a steady source of instructions, so the portal renewal feels less like a hostage situation. Book a call and we’ll show you what your CRM is worth.
