'Lead quality' is a phrase that gets thrown around constantly in the lead generation industry, but it's rarely defined with any precision. Every provider claims their leads are 'high quality,' yet the actual quality varies enormously. If you're buying leads — from us or anyone else — you need a clear framework for evaluating what you're actually getting.

Here are the factors that genuinely determine whether a lead is high quality, and how to assess them.

1. Verification

The most basic measure of lead quality is whether the contact information is accurate. A lead with a wrong phone number is worthless regardless of how well-qualified the consumer is. Verification is the process of confirming that the contact details are genuine before the lead reaches you.

SMS verification is the gold standard for phone number validation. The consumer receives a code via text and must enter it to complete their enquiry. This confirms the number is real, active, and in the consumer's possession. Not all providers do this — many skip it because it reduces their lead volume by 15-25%. If a provider doesn't SMS-verify, ask why.

Email verification checks whether the email address format is valid and whether the domain exists. More advanced verification checks whether the mailbox is active. This is less critical than phone verification for industries where the primary contact method is phone, but it matters for email-driven follow-up sequences.

Phone number validation (HLR lookup) checks the phone number against mobile network databases to confirm it's a valid, active UK mobile number. This catches numbers that don't exist, have been disconnected, or are formatted incorrectly.

Ask any provider: 'How do you verify lead contact details before delivery?' If the answer is vague or amounts to 'we check the format,' that's not real verification.

2. Exclusivity

An exclusive lead is sold to one buyer. A shared lead is sold to two, three, or sometimes five or more buyers simultaneously. This single distinction affects conversion rates more than almost any other factor.

When a consumer receives one call from one adviser, the experience is professional and expected. When they receive four calls within minutes from four competing brokers, the experience is chaotic and off-putting. Many consumers stop answering their phone entirely, and the conversion rate for everyone drops.

Shared leads are cheaper on a per-lead basis, but when you factor in the lower contact rate and dramatically lower conversion rate, the cost per acquired client is typically higher than with exclusive leads. A £30 exclusive lead that converts at 12% costs £250 per client. A £10 shared lead that converts at 3% costs £333 per client — and requires far more effort.

Some providers claim leads are 'semi-exclusive' (sold to 2-3 buyers) as a compromise. We'd argue this is the worst of both worlds — you're still competing, just with fewer people. If exclusivity matters to you (and it should), insist on genuinely exclusive leads and verify that the provider's business model supports it.

3. Intent Level

Not all enquiries represent the same level of buyer intent. A consumer who searches Google for 'mortgage broker near me' and fills in a detailed form has strong intent — they're actively looking for help and are ready to speak to someone. A consumer who clicks on a Facebook ad, glances at a form, and submits their details while scrolling through their feed has lower intent — they may be interested but aren't necessarily ready for a conversation right now.

Both types of leads can convert, but they require different follow-up approaches. High-intent leads respond well to an immediate phone call. Lower-intent leads may need nurturing — a helpful email, followed by a call a day or two later, followed by ongoing content that keeps you top of mind until they're ready.

When evaluating a provider, ask about their lead sources. Leads from Google Search generally have higher intent than leads from social media display ads. Leads from owned comparison websites (where the consumer actively sought out advice) tend to convert well. Leads from incentivised offers or prize draws tend to convert poorly because the consumer's motivation was the incentive, not the financial product.

4. Data Completeness

A lead with just a name and phone number is harder to work with than a lead that includes the consumer's specific requirements, timeline, and circumstances. The more qualifying data a lead contains, the better you can prepare for the call and the more relevant your initial conversation will be.

For mortgage leads, useful qualifying data includes: mortgage purpose (purchase/remortgage), approximate property value, deposit amount, employment status, timeline, and whether they're a first-time buyer. This information allows you to research suitable products before the call, which demonstrates competence and saves time.

However, there's a trade-off. More form fields mean more friction, which means fewer completions. A 15-field form will produce highly qualified leads, but at very low volume and very high cost per lead. A 3-field form will produce high volume at low cost, but with limited qualifying information and more tyre-kickers.

Good providers find the balance — enough fields to qualify the lead meaningfully without creating so much friction that genuine consumers abandon the form. At Lurvo, our forms typically have 6-10 fields split across multiple steps, which gives useful qualification data while maintaining reasonable completion rates.

5. Recency

A lead generated today is worth dramatically more than a lead generated last week. Consumer intent decays rapidly — the motivation that prompted someone to fill in a mortgage enquiry form fades within hours, not days. By the time a lead is a week old, the consumer may have already spoken to someone else, decided to wait, or simply forgotten they made the enquiry.

Real-time delivery means the lead arrives within seconds or minutes of the consumer completing the form. This gives you the best possible chance of reaching them while their interest is at its peak. Some providers batch-deliver leads — sending you a list at the end of the day or even the end of the week. These leads are already stale before you receive them.

Even worse are 'aged leads' or 'recycled leads' — leads generated days, weeks, or months ago that are sold at a discount. While they're cheap, the contact rates and conversion rates are so low that they're rarely worth the effort. If a provider is selling leads at suspiciously low prices, there's a good chance the data isn't fresh.

Ask your provider: 'How quickly after the consumer completes the form is the lead delivered to me?' Anything more than a few minutes should raise questions.

6. Source Transparency

Reputable lead providers can tell you exactly where their leads come from — which platforms, which websites, and which types of campaigns. They can show you examples of their ads and landing pages. They can explain their qualification process in detail.

If a provider is vague about their sources — 'we use various online channels' — or reluctant to show you their ads and forms, that's a concern. It could mean they're buying leads from third parties (adding a markup without adding value), using questionable traffic sources, or generating leads through methods that don't produce genuine consumer intent.

Transparency about sources isn't just about trust — it helps you understand the type of consumer you'll be speaking to. A lead from a Facebook video ad about first-time buyer mortgages will be a different conversation from a lead from a Google search for 'remortgage my house.' Knowing the source helps you tailor your approach.

7. Compliance and Consent

A lead without proper consent is not just low quality — it's a legal liability. Under GDPR, you need demonstrable evidence that the consumer consented to being contacted by a financial adviser about their specific enquiry. The consent must be explicit, informed, and specific — a pre-ticked box or a vague privacy policy doesn't cut it.

Ask your provider: 'Can you provide the exact consent wording for any lead?' and 'Can you produce a full audit trail — timestamp, IP address, and form version — if requested?' A quality provider will answer both questions with a straightforward yes. If they hesitate or can't, walk away.

At Lurvo, we maintain full consent records for every lead and can produce them on request. This protects both our clients and the consumers whose data we handle.

How to Evaluate Your Current Provider

If you're already buying leads, here's a quick assessment framework. Score your provider against each of the seven factors above:

  • Are leads SMS-verified? (Yes/No)
  • Are leads exclusive? (Exclusive/Semi-exclusive/Shared)
  • What's the primary source? (Search/Social/Owned sites/Unknown)
  • How many qualifying fields? (3-5/6-10/10+)
  • Is delivery real-time? (Seconds/Minutes/Hours/Batched)
  • Can they show you their ads and forms? (Yes/No)
  • Can they produce consent records? (Yes/No)

No provider will score perfectly on every dimension — there are always trade-offs between quality, volume, and cost. But this framework helps you make informed comparisons and understand exactly what you're paying for.

The cheapest lead is almost never the best value. The most expensive isn't necessarily either. The best lead for your business is the one that converts at a rate that makes your unit economics work — and quality, as defined by the factors above, is the biggest driver of conversion.
