19 Six Media Research • 2026
A practical benchmark guide for mortgage brokers measuring paid lead generation.
Cost per lead gets most of the attention. It should not. This report sets out the metrics that matter across the journey from impression to completed mortgage business — and explains how 19 Six Media interprets them.
How to use this report
Mortgage lead performance changes with audience, region, proposition, seasonality, qualification, budget, creative and the broker's follow-up process. A single UK-wide “average mortgage lead cost” can therefore be misleading.
We recommend benchmarking the whole funnel. A campaign with a higher CPL can be commercially stronger if more enquiries answer, book and complete. Equally, a very low CPL can hide weak intent.
Core mortgage lead benchmarks
| Metric | What it tells you | What to compare it with |
|---|---|---|
| CTR | Whether the advert is earning interaction. | Creative, audience, hook and placement. |
| Link CTR | Whether people are taking the next step. | Message-to-offer alignment and intent. |
| Cost per enquiry | Acquisition efficiency at lead level. | Contact, appointment and completion rates. |
| Contact rate | How many enquiries become real conversations. | Speed-to-lead, call attempts, WhatsApp/email and data quality. |
| Appointment rate | How efficiently conversations become advice opportunities. | Qualification, opening script and proposition. |
| Completion rate | How much lead flow becomes mortgage business. | Case fit, advice process, lender outcome and pipeline maturity. |
| Cost per completed case | The acquisition cost closest to commercial value. | Revenue, procuration fee, protection opportunity and lifetime value. |
Observed campaign example
One 30-day regional mortgage campaign managed by 19 Six Media generated 209 enquiries from £300.92 of advertising spend. The campaign recorded a £1.44 cost per lead, 129 conversations and 37 completed mortgages.
This is a campaign example, not a forecast for every broker. It demonstrates why lead cost becomes more meaningful when it is connected to contact and completion data.

Interpreting CPL
A first-time buyer campaign in one region should not automatically be judged against a specialist borrower campaign somewhere else. Qualification can also raise CPL while improving the proportion of useful conversations.
Meta benchmarks
When a Meta mortgage campaign underperforms, CPL is the symptom, not always the cause. Start higher in the funnel. Is the creative earning attention? Are people clicking through? Does the proposition match the audience? Is the form filtering appropriately? Then look at what happens after submission.
This is the logic behind Demand Engineering®: Person, Problem and Product shape the campaign, while qualification, nurture, follow-up and outcome data shape the optimisation.
Market context
The mortgage intermediary channel is substantial, which makes efficient customer acquisition commercially important. But marketing measurement should not encourage poor outcomes or prioritise volume over suitability.
Lead generation is the beginning of a regulated advice journey, not the end. Brokerages should maintain appropriate records, processes and oversight, and judge marketing in the context of customer outcomes as well as acquisition performance.
Methodology
We separate advertising diagnostics from commercial outcomes. CTR and link CTR help diagnose creative and traffic. CPL measures enquiry acquisition. Contact, appointment and completion data show whether those enquiries become useful opportunities.
Where this report gives a specific campaign result, it is identified as an observed 19 Six Media result. Reference points are used as internal operating diagnostics rather than claimed as representative averages for every UK mortgage brokerage.
The report will be updated as additional campaign data can be aggregated and published responsibly, allowing future editions to add larger-sample medians, ranges and segmentation by campaign type.
Frequently asked questions
There is no reliable universal figure. Cost varies by audience, region, channel, proposition and qualification. CPL should be interpreted alongside contact, appointment and completion performance.
Track advertising diagnostics such as CTR and link CTR, acquisition measures such as CPL, and commercial measures including contact rate, appointment rate, completion rate and cost per completed case.
No. A lower CPL can be attractive, but lead value depends on intent, fit, contactability and downstream conversion. A more expensive enquiry can produce a better commercial result.
19 Six Media uses 2%+ CTR and 1%+ link CTR as practical diagnostic reference points. They are not universal industry averages and should be interpreted in the context of campaign objective, placement, audience and conversion performance.
