I remember the exact moment a franchise partner realised what a shared lead platform was actually costing him. He was paying £60 a lead, felt reasonable on paper, until he worked out that the same homeowner’s details had gone to four other installers at the exact same moment, and he was racing all of them to be first on the phone.
His real close rate on those leads sat around 12%. His true cost per booked job was closer to £500, not £60.
I’ve built and run lead generation systems at a boiler and solar installation business that scaled past £65 million in turnover, so I’ve bought leads from platforms, built exclusive organic pipelines, and watched both sides of this comparison play out with real budget on the line.
This post lays out the honest maths between the two, because the sticker price on a lead generation platform genuinely hides the real economics underneath it.
What’s The Actual Difference Between A Shared Lead And An Exclusive Lead?
This distinction matters more than almost anything else in this comparison, and it’s worth being precise about it before looking at any numbers. A shared lead, the standard model on most home improvement lead platforms, gets sold simultaneously to three to eight competing businesses the moment a homeowner submits an enquiry.
An exclusive lead, whether bought individually or generated through your own organic search presence, goes to you alone.
Why Does This Distinction Change The Entire Economics?
Because the homeowner’s behaviour is completely different depending on which type of lead they are. With a shared lead, they’re expecting multiple calls, often within minutes of each other, and the decision frequently comes down to whoever calls first or quotes the lowest price, not who does the best work.
With an exclusive lead, the customer reached out to you specifically, they’re not fielding competing calls, and the conversation is a genuine consultation rather than a race.
What Do These Platforms Actually Cost Once You Factor In Close Rate?
This is where the sticker price genuinely misleads business owners, and it’s worth walking through the real maths properly.
How Do Shared Leads Actually Perform?
Shared leads on UK home improvement platforms typically cost £8 to £30 per unit, which looks appealing against other channels at first glance. But close rates on shared leads consistently run 5% to 20% across independent studies, because you’re one of several businesses the homeowner is simultaneously comparing, and price frequently decides the outcome rather than quality of work.
Take a mid-range example, a £20 shared lead closing at 12%, and your genuine cost per booked job works out to roughly £167. Push the close rate down to the lower end some studies report, and that figure climbs past £250 or £300 for the same nominal lead price.
How Do Exclusive Leads Compare?
Exclusive leads, whether purchased directly or generated through SEO and your own Google Business Profile, cost considerably more upfront, typically £45 to £120 per enquiry on UK platforms, but convert at 12% to 40% depending on the source and how quickly you respond.
A £75 exclusive lead closing at 25% works out to roughly £300 per booked job, broadly comparable to shared leads once you account for the conversion difference, but with none of the multi-contractor bidding war that tends to drag average job value down.
How Does Organic Search Compare To Both?
This is where the comparison genuinely tips in one clear direction. Leads generated through your own organic search presence, Google Business Profile enquiries and rankings you’ve built rather than paid for per unit, convert at 30% to 50% because the homeowner chose you specifically after their own research, not because a platform matched them to you alongside several competitors.
Once a campaign is genuinely established, the marginal cost of each additional organic lead approaches zero, since you’re not paying a platform fee every single time someone enquires. SEO-generated leads close at an average of 14.6%, compared to just 1.7% for outbound and shared lead sources according to research cited across multiple UK marketing studies, a genuinely stark gap that holds up consistently across different sectors.
Why Do Shared Leads Damage More Than Just Your Marketing Budget?
Beyond the raw cost per job, there’s a genuine operational cost to running your sales process on shared leads that rarely makes it into the pitch a lead platform gives you.
What Does Racing Competitors For The Same Enquiry Actually Cost Your Team?
Your sales team spends time calling and following up on leads that convert at single-digit rates a meaningful proportion of the time, time that could otherwise go towards genuinely qualified enquiries.
Homeowners fielding multiple calls from competing installers within minutes of submitting a form frequently report frustration with the entire experience, which reflects on your business even when the platform, not you, created that experience.
And because price becomes the primary differentiator in a multi-bid scenario, average job values on shared leads tend to run lower than on leads where a customer chose you specifically, since there’s less room to sell on quality, warranty or service when you’re one of five quotes sitting in someone’s inbox.
Does This Comparison Change Depending On How Established Your SEO Already Is?
Genuinely, yes, and this is worth being honest about rather than pretending SEO is instantly cheaper from day one.
What Does The Timeline Actually Look Like?
In the first three to six months of an SEO campaign, before rankings and Google Business Profile authority have properly built, your organic lead volume will likely sit below what a lead platform can deliver immediately. This is exactly why I don’t recommend businesses switch off lead platforms the moment they start investing in SEO.
The sensible approach is running both in parallel, using platform leads to sustain volume while SEO compounds in the background, then gradually reducing platform reliance as organic enquiries climb, using your actual platform cost per booked job as the benchmark for judging when that transition genuinely makes sense.
At What Point Does SEO Clearly Overtake Platform Economics?
Most businesses following this pattern see the crossover point somewhere between month six and month twelve, where the accumulated organic visibility starts producing enough volume at a genuinely lower marginal cost that continuing to pay £150 to £300 per booked job through platforms becomes difficult to justify for anything beyond overflow capacity during unusually busy periods.
Why Does This Comparison Matter Even More For Boiler, Solar And Heat Pump Businesses Specifically?
Average job values in this sector run considerably higher than most trades, often several thousand pounds for a single heat pump or solar installation, which means the gap between a 12% and a 35% close rate translates into genuinely significant revenue difference every single month, not a marginal rounding error.
You’re also competing against national comparison giants like MoneySuperMarket, GoCompare and uSwitch for exactly the same searches that feed both lead platforms and organic search, which makes owning your own search visibility considerably more valuable than renting access to leads that a platform is simultaneously selling to your direct competitors.
Every senior person on our team at Essheo has spent eight or more years building exactly this kind of owned, exclusive lead generation in genuinely hard to rank sectors, including direct experience running both paid lead acquisition and organic strategy simultaneously at a business that scaled past £65 million in turnover.
The strategies we’ve designed and implemented within our SEO service for home improvement service based businesses have contributed to over £45 million in combined client revenue across the last two years alone, built specifically around reducing reliance on platforms that sell your customer’s details to your competitors at the same moment they reach you.
Ready To Stop Racing Your Competitors For The Same Customer?
If you’re currently paying for shared leads and calculating your marketing cost by the sticker price rather than the true cost per booked job, that number is very likely considerably higher than you think once the maths is done properly.
I set Essheo up to help boiler, solar, heat pump, air conditioning and EV charger installation businesses build a genuinely owned, exclusive lead pipeline through SEO, one where every enquiry chose you specifically rather than being distributed to four other installers at the exact same moment.
Book a strategy call with me today and let’s work out the real cost of your current lead sources, and what owning that pipeline could look like instead.
