- Shared sellers' own pages say each enquiry goes to up to three installers. Exclusive sellers say one.
- Compare on cost per sale, not cost per lead. Exclusive usually wins because more people pick up and nobody has called first.
- Shared leads still suit firms that call within minutes, have spare callers and need volume.
- Exclusive is a promise about who gets the lead. Ask what happens to a lead you return, and get it in writing.
- The ICO says consent bought in from someone else only covers you if you were named. Ask to see the wording.
The short answer
A shared lead is one enquiry sold to several firms. An exclusive lead is sold to one. The person asked once either way; the difference is how many phones ring afterwards.
Exclusive usually costs less per sale. But the word is easy to print, so check it.
How each one works
Shared sellers say so on their own pages. One solar comparison site tells installers each lead is shared with a maximum of three competitors. Another tells homeowners their details go to up to 3 vetted installers.
Exclusive sellers say every lead goes to one installer only, and that exclusive costs more.
- Sent to up to three installers
- Lower price per lead
- The first caller often wins
- The homeowner expects several calls
- Sent to one installer
- Higher price per lead
- No race to the phone
- Room to follow up properly over days
What happens to a shared lead in its first hour
Speed decides shared leads. Studies of web enquiries found firms that call within the hour are far more likely to qualify the lead than those that wait. With a shared lead, you're racing other firms, not just the clock. Our speed to lead guide has the figures.
- You asked for solar quotesForm sent. Your details go to three installers.
- Incoming call: Installer 1Answered. Survey booked for Thursday.
- Incoming call: Installer 2Declined. Already sorted, thanks.
- Missed call: Installer 3Ignored. Then a voicemail the next day.
- Installer 3 marks it a bad leadIt was fine when it arrived. It was just third.
Why it shows in your numbers
Three things move cost per sale in exclusive's favour: more people pick up when nobody else has rung, the first conversation is calmer, and your team can follow up over days instead of dialling fast and moving on.
Run your own numbers below: price per lead, the share you speak to, and the share who buy.
What does a sale really cost you?
The price per lead is only part of it. Put in your own numbers.
Out of 100 leads you speak to 60 and 7 buy.
Who should still buy shared leads
Shared leads are a legitimate, cheaper product. Some firms do very well on them. The question is whether your team is built to win the race, every time, at volume.
Shared is also a cheap way to test a new area before you commit.
- Call within minutes, all day
- Have callers with spare hours
- Close well on the first call
- Track cost per sale every week
- Call back within hours, not minutes
- Are the owner and the salesperson
- Sell on surveys, trust and follow-up
- Work a tight local area
Phrases that sound exclusive and aren't
Read the wording closely. These phrases leave room for the same lead to reach other firms, now or later.
- Limited to three buyers: shared, with a cap.
- Semi-exclusive or priority: you get it first, then it's sold again.
- Exclusive for 30 days: after that it can go to someone else.
- Exclusive to your area: one buyer per postcode, but the person may still be sold to other trades.
- Not resold by us: whoever supplied it to them may still sell it on.
- Verified: ask what. Phone, email, postcode and consent are different checks.
- Real time: fast delivery says nothing about who else gets it.
What we've seen: exclusive gets you a chance, not a sale
Every lead we sell goes to one buyer at a time. Even so, results between buyers differ hugely, on the same kind of lead. The lead is rarely the whole story.
Three things from our solar buyers this autumn.
Ask what happens to a lead you return
Most buyers forget to ask this. If you return a lead, does it go back on sale, and to how many firms? Ours can go to one other buyer, never two at once. That's fine, as long as the supplier says so plainly.
- We don't really track that
- It goes back in the pool
- Depends on the partner
- No written returns rule
- It goes to one other buyer, never two at once
- Here's our returns rule in writing
- Here's what we check before delivery
- Here's how fast we replace a bad lead
Consent is part of exclusivity
The ICO says consent must name any third party that will rely on it, and bought-in consented data only covers you if your organisation was specifically identified. It also says it isn't enough to simply accept a third party's assurances.
- You may hear from selected partners
- No firm or type of firm named
- No record of when or where it was given
- Names the installer, or says exactly what kind of firm will call
- Says how they'll be contacted: phone, text, email
- Kept with a time, the page and the wording version
What we'd do: five checks, then a trial
Put the same questions to every supplier, keep the answers on file, then test before you commit.
- 1Get exclusivity in writing
Each lead sold once, to you, and what happens if you return it.
- 2See the page and the consent
The page the person filled in, and the exact wording they agreed to. Does it cover you?
- 3Ask what's checked
Phone, email, postcode, TPS. And how bad leads are replaced or credited.
- 4Trial 50 to 100 leads
Call in minutes, try about six times over a few days, text between calls from your business.
- 5Judge on cost per sale
Track contacted, booked and sold per supplier. If shared wins on cost per sale for you, buy shared.

Questions to vet a lead supplierThe questions to send every supplier, and what a good answer looks like.
You are a buyer's adviser for UK [trade] firms that buy leads. I'm [company], covering [areas], and I want about [number] leads a month. I'm talking to these suppliers: [names]. Write: 1. 15 questions to send every supplier, grouped under: exclusivity (sold once? to how many?), returns (what happens to a lead I return, and does it go back on sale?), where the traffic comes from (which ads, which pages, what the ads promise), checks before delivery (phone, email, postcode, TPS), consent (the exact wording and page the person saw, and does it name me or my type of firm?), price (VAT included or not, minimums, caps) and replacements for bad leads. 2. For each question, what a clear answer looks like and what answer should worry me (e.g. "it goes back in the pool", "depends on the partner"). 3. A short, polite email I can send each supplier with the questions, asking for answers in writing. Rules: neutral, not accusing. Don't assume any supplier is good or bad. Plain UK English.
Build my trial scorecardA sheet to compare suppliers on a 50 to 100 lead trial.
You are setting up a trial scorecard for [company], a [trade] firm comparing lead suppliers. We'll trial 50 to 100 leads from each of: [supplier names, price per lead, exclusive or shared]. Our gross profit on an average job is about £[amount]. Build a Google Sheets layout with: 1. A lead log tab: date and time received, supplier, time of first call, number of tries, reached (yes/no), booked (yes/no), sold (yes/no), returned (yes/no and why), notes. 2. A summary tab per supplier: leads, returned, reached %, booked %, sold %, total spend (with VAT if charged), cost per lead, cost per booking and cost per sale, with the exact formulas. 3. A line that flags any supplier whose cost per sale is above the most I can afford (gross profit x [10 to 30]% I'm willing to spend to win a job). 4. A weekly 10-minute review checklist, and the rule for deciding at the end of the trial. Rules: treat every supplier the same. Judge on cost per sale, not cost per lead. If shared wins on cost per sale for us, say so.
Read a supplier's terms for hidden sharingPaste the sales page or terms and spot the phrases that leave room to resell.
Here is a lead supplier's sales page and terms: [paste]. Find every phrase about who else can receive the same lead, now or later. Look especially for: "limited to three buyers", "semi-exclusive" or "priority", "exclusive for 30 days", "exclusive to your area", "not resold by us", "verified" and "real time". For each one: quote it, explain in one line what it allows, and write the follow-up question I should ask. Then tell me what's missing: returns, what happens to a returned lead, the checks done, and the consent wording. This is not legal advice. If something needs a lawyer or a compliance adviser, say so.
Check the consent on a sample leadWhether the wording the person agreed to covers you.
I buy leads as [company], a [trade] firm. My supplier sent this for a sample lead: the page the person filled in [paste or describe], the consent wording they agreed to [paste], and the record they keep [time, page, wording version, if given]. Check, in plain points: 1. Does the wording name my firm, or say exactly what kind of firm will call? 2. Does it say how they'll be contacted: phone, text, email? 3. Is there a record of when and where it was given, and which wording? 4. Is it the kind of "selected partners" wording that wouldn't cover me? Then list the questions to send the supplier, and what I should keep on file. This is not legal advice: check anything uncertain with a compliance adviser.
Win more shared leadsIf you buy shared, a plan to be the first good call.
I buy shared leads (sent to up to three firms) as [company], a [trade] firm in [area]. We have [number] callers working [hours]. Today we usually call within [time]. Write a plan to win the race on shared leads: 1. How to get our first call out within a minute or two, every time, with the people we have. 2. A first 20 seconds on the phone that sounds different from the other callers: who we are, why we're calling, one useful question. 3. What to do when they say "someone's already called me" (a fair, short reply that isn't pushy). 4. A text to send straight after a missed call, from our business. 5. The weekly numbers to track to know whether shared is working for us: contact rate, booked rate, cost per sale. Rules: honest, no pressure, no running down other firms, no promises we can't keep.
Common questions
Are exclusive leads worth paying more for?
Usually, because nobody else has called first and more people pick up. Compare suppliers on cost per sale after a trial of 50 to 100 leads, not on the price per lead.
How do I know a lead is really exclusive?
Ask for it in writing, ask where the traffic comes from, and ask to see the page and the consent wording. Ask what happens to leads you return. A supplier that means it will answer plainly.
Are shared leads bad?
No. They're a cheaper, legitimate product that suits firms with fast callers, spare capacity and a need for volume. The risk is paying an exclusive price for a shared lead.
Does exclusive mean the homeowner won't hear from anyone else?
No. It means the supplier sold that enquiry to you only. The homeowner can still ask other firms for quotes themselves.
What if I find the same lead was sold to someone else?
Send the supplier the lead details and ask for a credit under your agreement. If it happens more than once, stop buying from them.
