Some solar companies are paying £150 for a lead that’s already been called by three competitors. Others are generating better quality leads for free. The difference isn’t budget. It’s strategy.
Having helped solar and renewable energy businesses build lead generation engines that eventually cost nothing to run, we know that the price of a lead and the true cost of a lead are two very different things.
This guide breaks down exactly what you should expect to pay across every lead generation method, what that actually means for your bottom line, and why lead quality is the conversation most solar businesses aren’t having but should be.

The Three Types of Solar Lead
Before we get into costs, it helps to understand what you’re actually buying.
Solar leads broadly fall into three categories, each with a very different price point, quality level, and conversion rate.
Shared leads are generated by a third party and sold to multiple installers at the same time. You might be one of three, four, or even five companies contacting the same prospect within hours of each other.
Exclusive leads are sold to one installer only. The prospect hasn’t been contacted by a competitor, which gives you a significantly better chance of converting the enquiry.
Organic leads come through your own digital presence, whether that’s your website ranking in Google, your Google Business Profile, or content you’ve published. No third party involved, no cost per lead, and typically the highest quality of the three.
What Do Shared Solar Leads Cost?
Shared leads are the cheapest option on paper, typically sitting between £20 and £50 per lead in the UK.
They’re popular because the upfront cost feels low and the volume can be high. But the economics often fall apart when you look more closely.
When a prospect has been contacted by four competitors before you even pick up the phone, your chances of converting that lead drop dramatically regardless of how good your sales team is.
Shared lead providers are also incentivised to generate volume rather than quality. The leads may come from low-intent sources, comparison websites, or broad advertising that attracts people who are vaguely curious rather than actively looking to buy. Conversion rates on shared solar leads typically sit between 5% and 10%, meaning you might need to buy fifteen to twenty leads to close one job.
At £30 per lead, that’s £450 to £600 to acquire a single customer. For a residential installation, the margin might just about support that. For a business trying to scale, it becomes expensive very quickly.

What Do Exclusive Solar Leads Cost?
Exclusive leads cost considerably more upfront, typically ranging from £50 to £150 per residential lead in the UK. Commercial solar leads via paid channels can push significantly higher, sometimes £200 to £300 or more depending on location and competition.
The higher price reflects the fact that you’re the only installer receiving that enquiry. Conversion rates are meaningfully better as a result, often sitting between 15% and 25% for well-qualified exclusive leads.
The maths can work in your favour with exclusive leads, but only if the lead source is genuinely high quality and the exclusivity is real.
Some lead providers claim exclusivity but sell the same lead to multiple “exclusive” buyers in different regions, or generate leads through methods that attract low-intent prospects. Always ask how leads are generated, what the average conversion rate is across their client base, and whether you can speak to existing customers before committing.
What Do Paid Search Leads Cost?
Running your own Google Ads campaigns puts you in control of the lead generation process rather than relying on a third party. You set the targeting, the messaging, and the budget.
The cost per lead through Google Ads varies significantly depending on your location, the competitiveness of your market, and the quality of your campaigns. For residential solar in the UK, expect to pay anywhere from £80 to £250 per lead. Commercial solar terms are more competitive and can push higher.
The advantage of Google Ads over buying leads is control. The disadvantage is that the moment you stop paying, the leads stop completely.
There’s no compounding effect, no asset being built, and no long-term return on the money you’ve spent. Every lead you generate through paid search has a cost attached to it indefinitely.

What Do Organic Leads Cost?
Once your organic strategy is established, the cost per lead is effectively zero.
That’s not a marketing claim. It’s simply how organic search works. A blog post, a landing page, or a Google Business Profile that ranks well in search generates enquiries continuously without any ongoing spend. The investment is in building the strategy in the first place, not in maintaining it month to month.
This is precisely what we built for Effective Energy Group, and the results speak for themselves.
Over twelve months using purely organic strategies, their daily clicks grew from 127 to 371, monthly impressions from 15,000 to 42,000, and leads tripled. No paid advertising. No lead buying. A sustainable pipeline built on content, SEO, local search, and email automation that continues to deliver long after the initial work is done.
According to HubSpot, organic search generates over 53% of all website traffic. For solar businesses with a well-optimised presence, organic leads consistently outperform paid leads on both volume and quality over a twelve to eighteen-month period.
Why Lead Quality Matters More Than Lead Cost
Here’s the conversation most solar businesses aren’t having.
A £20 shared lead that converts at 5% costs you £400 per customer acquired. A £0 organic lead that converts at 30% costs you nothing per customer acquired. The cheapest lead on paper is often the most expensive lead in reality.
Lead quality is the single biggest variable in your true cost per acquisition, and it’s almost entirely determined by how the lead was generated.
Organic leads tend to convert at higher rates for a simple reason. The prospect found you because they were actively searching for what you offer. They’ve read your content, seen your case studies, and arrived at your website with intent. By the time they fill in an enquiry form, they already have a degree of trust in your business.
Shared and paid leads, by contrast, often come from people who clicked on an ad or filled in a comparison form on impulse. The intent is lower, the trust is absent, and the sales process has to work much harder to bridge that gap.
Lead Quality and Our Work With Effective Energy Group
Lead quality was one of the most significant improvements we delivered for Effective Energy Group, though it’s harder to show in a headline number than traffic or impressions.
As their organic presence grew and their content established genuine authority in the market, the profile of their inbound leads shifted. Prospects were arriving better informed, more confident in the brand, and further along in their decision-making process. The sales team were spending less time educating and qualifying and more time closing.
That shift in lead quality, not just lead volume, is one of the real long-term gains of building an organic led strategy.
It’s something that rarely gets talked about in marketing conversations focused on cost per lead, but it has a meaningful impact on revenue, margins, and the efficiency of your sales operation.
So What Should You Actually Be Paying?
The honest answer is that lead cost targets vary significantly depending on your average job value, your conversion rate, and your margins.
A rough framework that works for most solar businesses:
- Residential installation average value: work back from a maximum 10% customer acquisition cost
- If your average residential job is worth £8,000, your maximum sustainable cost per acquired customer is around £800
- At a 10% conversion rate on shared leads at £40 each, you’d spend £400 to acquire one customer. That’s within budget but leaves no room for a worse conversion month
- At a 25% conversion rate on organic leads at £0 each, your acquisition cost is zero
The goal for any solar business with a long term mindset should be to use paid leads to generate revenue now while building an organic engine that progressively reduces your cost per lead toward zero.
That’s not an overnight process. It typically takes twelve to eighteen months for organic strategies to deliver meaningful volume. But the businesses that start that journey today are the ones paying nothing for leads in two years’ time.
Ready to Reduce Your Solar Lead Costs?
The most sustainable lead generation strategy for solar businesses isn’t the cheapest lead source. It’s the one that builds an asset over time, improves in quality as it grows, and eventually generates enquiries at no ongoing cost.
We helped Effective Energy Group build exactly that, tripling their leads in twelve months through purely organic strategies. The same approach works for solar businesses of all sizes, whether you’re currently buying shared leads, running paid ads, or starting from scratch.
