Facebook and Instagram ads generate solar leads by putting your offer in front of homeowners who weren't searching for it, which means you're creating demand rather than capturing it. Intent runs lower than Google, volume runs higher, and everything depends on two things: creative specific enough to stop a local homeowner mid-scroll, and follow-up fast enough to catch interest before it evaporates. This guide covers what works, what wastes money, and the compliance angle most solar ad guides skip entirely.
Do Facebook ads work for solar in the UK?
Yes, with the right expectations. A Meta lead hasn't compared quotes or read up on inverters. They saw something interesting while half-watching television and tapped it. That's not a worse lead than a Google search, it's an earlier one, and treating the two the same is where most installers' Meta budgets die. Expect more leads per pound, a lower survey rate, and a heavier qualification job. Priced accordingly, the channel scales in a way local search never can, because you're not limited by how many people happened to search this month.
The follow-up point is even sharper here than elsewhere. A scroller's interest is minutes deep. Research published in Harvard Business Review found firms contacting web enquiries within an hour were nearly seven times more likely to qualify them, and that was web enquiries, where someone deliberately sought a company out. A lead form tapped mid-scroll cools even faster. Treat every submission like a ringing phone or don't run the ads.
What creative actually converts for solar?
Specificity. The scroll is full of generic solar ads, panels against blue sky, stock families, vague savings claims, and homeowners have learned to slide past all of it. What stops the thumb is recognition: a real install on a roof that looks like their roof, on a street that looks like their street, with a number that sounds like a real household's number.
The creative checklist that keeps earning its money:
- Real installs, ideally local. Your photos from actual jobs, named area in the copy. "Installed last month in [town]" outperforms any stock composition.
- Real numbers, honestly framed. An actual customer's generation or export figures, presented as that customer's result, not a promise.
- Before and after the bill, where a customer will share it. Nothing sells like someone else's smaller bill.
- A concrete reason to act, without inventing urgency. Install lead times, seasonal generation, a genuine offer.
- Video from the scaffold. Thirty seconds of a real install going on, shot on a phone, beats polished brand video for this job.
What's the compliance trap in solar ads?
Green claims, and it catches solar advertisers specifically. UK ad rules on environmental claims are policed by the ASA, and their guidance on green claims is blunt: environmental and savings claims need substantiating, worst-case-buried-in-footnotes doesn't wash, and "typical" figures need to be genuinely typical. Solar ads promising specific savings to everyone, or leaning on grant-adjacent language that implies government money that isn't there, are exactly the pattern that draws rulings.
This isn't just about avoiding trouble. Ads that survive scrutiny are better ads, because the homeowner who arrives from an honest claim doesn't churn out of your funnel disappointed when the survey tells them the truth. The clickbait "government scheme" leads flooding parts of this market are precisely why bought leads so often close badly.
Lead forms or landing pages?
Lead forms convert more and qualify less; landing pages convert fewer and better. The honest answer is to test both against the metric that matters, cost per surveyed roof, not cost per lead. If you use lead forms, add two or three qualifying questions even though they cut volume, because the unqualified volume was never really volume. If you use a landing page, keep it to one promise and one form, same rules as for paid search pages.
Either way, wire the response before launching the campaign. The form that fires into a spreadsheet someone checks tomorrow morning has already lost most of what you paid for.
What audiences and exclusions matter?
Less than creative does, since Meta's targeting has got broader and its delivery smarter, but three settings still earn their keep: keep the geography tight to your genuine patch, exclude your existing customers (upload the list, it takes minutes and stops you paying to advertise at people who already bought), and let the platform optimise for the conversion you actually want, the qualified enquiry, not the click.
That customer list upload has a second use worth knowing: your old, unconverted enquiries make a strong retargeting audience. Although if you have a meaningful pile of those, showing them ads is the timid version of what actually works, which is reactivating them directly.
How much should you spend to test Meta ads?
Enough to buy a real sample of enquiries and follow them through to survey before judging. Work backwards from your numbers: whatever your cost per lead lands at in early days, you want 30 or more leads followed through the funnel before conclusions, because Meta results swing wildly on small samples. Budget for a proper test, run it four to six weeks, judge on cost per surveyed roof, and kill or scale based on that number and nothing shallower.
Frequently asked questions
Why are my Facebook solar leads poor quality?
Usually one of three: clickbait creative attracting bargain hunters, no qualifying questions on the form, or slow follow-up letting real interest die. Fix in that order and the "quality problem" mostly disappears.
Does Instagram work as well as Facebook for solar?
Run placements together and let delivery find your buyers. The homeowner demographics buying solar are thoroughly present on both.
Can I run solar ads to a postcode radius?
Yes, location targeting handles a radius around your base, which is exactly how it should be set. Tight patch, real drive times.
How long before Meta ads are profitable?
The learning phase needs conversion volume, so early weeks look worse than the settled state. Judge after the funnel has produced surveyed roofs, not after the first week's cost per lead.
