UK financial services brokers typically choose between two lead-buying models: exclusive lead providers (one buyer per lead) and aggregator or marketplace platforms (multiple buyers per lead). We sell exclusive leads, so we have a commercial interest — but the honest answer is that both models have use cases. This guide compares them side-by-side with real conversion maths, and tells you which model suits which broker profile. You should walk away knowing which to test first for your specific situation.
The two models
Exclusive lead providers sell each consumer enquiry to one broker only. Typical prices £10-£50 for mortgage and protection leads, £30-£100 for specialist (commercial, equity release, wealth management). The buyer is the only person contacting that consumer. Typical UK providers include Lurvo Digital, Quotezone, and Contact Centres UK.
Aggregator sites are consumer-facing platforms where people enter their requirements, then the platform matches them to 3-5 advisers from a panel. Each adviser pays a fee to access the lead and competes to convert. The largest UK aggregators in financial services are Unbiased, VouchedFor, Moneyfactscompare, Aviva Financial Advice Explained, and iContact Leads. Some operate per-lead pricing; others charge monthly membership with included matches.
How aggregator sites work
The consumer-facing experience is broadly: (1) the consumer fills in a form describing their needs, (2) the platform matches them to 3-5 advisers on its panel (sometimes more), (3) each matched adviser pays a fee and gets the consumer's details, (4) the advisers contact the consumer, (5) the consumer picks whichever they like best.
From the broker's perspective, this means you're competing against 2-4 other brokers for every enquiry. Speed-to-contact becomes the dominant factor: the broker who calls within 60 seconds is significantly more likely to win than one calling 30 minutes later. Unlike exclusive leads (where the consumer expects your call), aggregator consumers are prepared for multiple calls and often feel fatigue by the time the third broker rings.
Aggregator pricing typically falls in one of three models:
- Per-lead fees: £15-£40 per lead received, regardless of whether you convert. Used by Unbiased, iContact, Moneyfactscompare.
- Monthly membership with lead allowance: £100-£500/month for a fixed number of matches. Any additional matches at per-lead rate. Used by some VouchedFor tiers.
- Commission share on completion: You pay the platform 10-25% of your proc fee on any case that completes from one of their leads. Less common but used in some specialist aggregators.
Conversion economics
The numbers matter here. Using our 2026 benchmark data, here's a fair comparison for general mortgage leads:
Exclusive lead — typical maths
- Lead cost: £25
- Contact rate (reach the consumer): 68% median
- Appointment rate (of contacts): 45% median
- Case completion rate (of appointments): 35% median
- Overall conversion: 68% × 45% × 35% = ~10.7%
- Cost per completed case: £25 / 10.7% = £234
Aggregator lead — typical maths
- Lead cost: £15
- Contact rate (reach the consumer): 52% median (lower — consumer has 3-5 brokers calling)
- Appointment rate (of contacts): 28% median (lower — competitor brokers may already have been preferred)
- Case completion rate (of appointments): 32% median
- Overall conversion: 52% × 28% × 32% = ~4.7%
- Cost per completed case: £15 / 4.7% = £319
The headline lead cost is 40% lower on the aggregator, but cost per acquired client is roughly 36% higher. This pattern holds across most lead types we've compared, with the gap widening for life insurance and protection (consumers face more decision friction, so competition hurts conversion more).
Hidden costs of aggregator models
- Longer time per lead — you call more people, spend more time qualifying, reach more dead ends
- Admin overhead of tracking which platform each lead came from, since different platforms have different refund policies
- Brand dilution — some aggregators expect you to work within their consumer-facing brand, which means the relationship is theirs, not yours, for any future remortgages or referrals
- Consumer fatigue — advisers on the same panel sometimes complain about consumers who've already been called 3 times before yours lands, leading to poor first-call experience
When aggregators actually make sense
There are genuine use cases for aggregators — we don't want to pretend there aren't.
1. You have spare operational capacity and want volume
If your broker team has spare calling capacity and a genuinely fast follow-up process (sub-60-second response time), aggregators can be efficient. You're monetising capacity that would otherwise be idle, and you're comfortable accepting the 30-40% lower conversion in exchange for higher top-of-funnel volume.
2. You're testing a new specialism
Aggregators give you cheap volume to test whether a new lead type suits your business before committing to exclusive leads. If you convert well on aggregator leads, you'll convert better on exclusive leads. If you struggle on aggregators, exclusive won't rescue you — your process needs work first.
3. You have an extremely fast response process
Some brokers have operationalised sub-60-second response times using automated call routing, instant SMS, and always-on availability. These brokers can genuinely outcompete other panel members on speed and convert well on aggregators. For most brokers, this operational sophistication isn't realistic.
4. You want brand exposure at scale
Being on Unbiased or VouchedFor is partly a brand presence play — consumers who didn't pick you from the match may still recognise your name later. This matters more if you're building a firm rather than a one-broker business.
When exclusive wins decisively
1. You're a solo broker or small firm
Solo brokers and small firms (1-3 advisers) almost always find exclusive leads easier to work. The maths is more predictable, the admin is lighter, and the consumer experience is better. Most of our Lurvo Digital clients are firms of 1-5 advisers, and the aggregator model tends not to suit this scale.
2. You charge a client fee
Charging a client fee is harder when the consumer has been called by 3 other brokers who didn't charge fees. Exclusive leads give you a genuine first-conversation opportunity to explain your fee structure without price comparison pressure.
3. You specialise in complex cases
For adverse credit, commercial, bridging, equity release — exclusive is almost always better. Complex cases need a long conversation, not a 3-way race. Consumers in these categories also value the adviser's expertise more, which is hard to establish when they're speaking to 4 brokers in quick succession.
4. You want to build long-term client relationships
Repeat business and referrals depend on client loyalty. A consumer who came through an aggregator often identifies the platform as their 'broker finder', not you — they go back to the platform for their next remortgage, not to you directly. Exclusive lead relationships are cleaner to nurture.
A 5-question decision framework
- Can you respond to a lead within 60 seconds during business hours? If yes, both models are viable. If no, exclusive only.
- How many leads per week can you properly work? If 10 or fewer, go exclusive — your conversion rate matters more than unit cost. If 40+ per week and you have capacity, consider blending.
- Do you charge a client fee? Fee-charging brokers typically struggle with aggregators where consumers are price-comparing across fee-free alternatives. Exclusive is significantly better.
- What's your specialism? Mainstream purchase and remortgage cases can work on either model. Adverse credit, commercial, specialist protection, equity release — exclusive only.
- What's your operational sophistication? If you have automated lead routing, instant SMS, and sub-60-second call capability, you can compete on aggregators. If you're a solo broker returning calls between meetings, exclusive works better.
Most UK brokers should test exclusive first, get their process dialled in, and only consider aggregators once they have operational slack and want to test incremental top-of-funnel volume.
Next steps
If you want to test exclusive mortgage, protection, or specialist leads without contracts, get in touch with Lurvo Digital. A typical test batch is 20-30 leads over 2-3 weeks, which is enough to compare conversion against your current aggregator performance with real data.
