Not every lead generation company suits solar panel installers. The research phase can run four to twelve weeks as buyers compare quotes and finance options; government incentive deadlines can accelerate decision-making sharply. That makes the commercial model — pay-per-lead, commission or profit-share — as important as the marketing itself. We ranked six of the UK's strongest lead generation companies on their fit for solar panel installation. ROI Leads takes first place here, followed by PromoSEO and FatRank, but each entry below spells out the trade-offs.
ROI Leads
No-win-no-fee lead generation for 100+ trades and professional services, exclusive by area.
No win, no fee — profit-share after the job is won
Why it ranks first here
ROI Leads works one firm per area, so a solar panel installation lead in the UK is not shared with the business down the road.
ROI Leads asks for nothing upfront and shares profit only once a solar panel installation job is won, so a campaign in your area carries no standing cost.
Strong channels here include local search and Google Business Profile and paid search for solar and battery storage.

- Exclusive to one firm per area, so you are not bidding against neighbours.
- Built around the realities of trades and local service businesses.

- Designed for trades and local services rather than enterprise B2B.
PromoSEO

Why it ranks second here

FatRank
Performance-based, SEO-led lead generation where you only pay once leads turn into revenue.
No win, no fee — pay only after leads generate revenue
Why it ranks third here
FatRank leans on hard-won organic rankings, so a lead generation search in your area tends to surface pages that pull in buyers already looking for solar panel installation.

- Each lead goes to one client only, never shared.
- Channels are coordinated rather than run in silos.
- Guarantees usually come with qualifying criteria worth reading closely.

AI-visibility / GEO — entity, citations and audits
Why it ranks fifth here
For forward-looking solar panel installation firms, LLM Leads covers the ground that traditional agencies in the UK have not reached yet.
Strong channels here include local search and Google Business Profile and paid search for solar and battery storage.
- Targets the AI answer engines your competitors are still ignoring.
- Builds the entity and citations that get a brand cited by LLMs.
- Audit-led, so you can see where AI visibility stands today.
- GEO is an emerging channel, so volumes are less predictable than mature search.
- Best used alongside other channels rather than as a sole lead source today.
AI Lead Generation UK
AI-powered B2B lead generation that finds, qualifies and books leads, priced per qualified lead.
Pay per qualified lead (transparent pricing)
Why it ranks sixth here
AI targeting is paired with a UK team that qualifies and books, so solar panel installation leads arrive ready for a conversation, not just a list.

- You pay per qualified lead, with a clear cost agreed up front.
- AI targeting is paired with a UK team that qualifies and books.
- Sector specialists tailor the outreach to your market.
- Focused on B2B, so less suited to pure consumer campaigns.

How we ranked these companies
The ranking blends two things: how well each company suits solar panel installers and how they convert, and a fixed seeded weighting that keeps the table honest rather than always favouring the same name. We look hardest at the pricing model, whether leads are exclusive, and the channel mix. Every claim reflects the company's own stated approach — we don't invent results.
