If you run a solar installation business in the UK, you already know the market is competitive. There are over 3,500 MCS-certified installers fighting for the same pool of homeowners and businesses searching for solar. The question is not whether to market — it's where to put your budget for maximum return.
The Lead Generation Landscape
Solar installers typically acquire leads through five channels: Google Ads (PPC), organic search (SEO), social media, referrals, and lead generation platforms. Here's how they compare in 2026:
| Channel | Cost Per Lead | Lead Quality | Close Rate | Effective CPA |
|---|---|---|---|---|
| Google Ads (PPC) | £30-£80 | Medium | 8-15% | £250-£700 |
| Organic Search (SEO) | £5-£20 | High | 15-25% | £30-£120 |
| Social Media | £15-£40 | Low-Medium | 5-10% | £200-£500 |
| Lead Gen Platforms | £20-£50 | Low (shared) | 3-8% | £300-£800 |
| Referrals | £0-£200 | Very High | 30-50% | £0-£500 |
The data consistently shows that organic search delivers the lowest cost per acquisition. Homeowners who find you through Google have already self-qualified — they've searched for "solar panel installers [their area]" and chosen to contact you. That intent makes them far more likely to convert than someone who clicked a Facebook ad.
Why Local SEO Dominates for Solar
Solar installation is fundamentally a local service. Nobody hires an installer 200 miles away. This makes local SEO — ranking in Google's map pack and organic results for "[service] [location]" searches — the single most valuable marketing investment a solar installer can make.
The installers dominating local search results share common traits: optimised Google Business Profile with regular reviews, dedicated location pages on their website for every town they serve, consistent NAP (Name, Address, Phone) across all directories, and genuine local content that demonstrates knowledge of the area.
Content That Generates Solar Leads
The highest-converting content for solar installers is not generic blog posts about "how solar panels work." It's specific, local, and commercial:
- Location pages — "Solar Panel Installation in [Town]" with genuine local data: council climate targets, average sunshine hours, local property types, and planning considerations specific to that area
- Sector pages — Targeting commercial niches like solar for schools, hotels, or factories
- Cost guides — Transparent pricing pages with real numbers. The Cost of Solar demonstrates the format that ranks
- Case studies — Real installations with photos, system specs, and measured performance data
The Specialist Advantage
Generalist solar installers ("we do everything for everyone") struggle to rank for any specific term. Specialists win because they create deeper content around their niche. A company focused on commercial solar can rank for dozens of business-specific keywords that a generalist never targets.
This specialisation extends to marketing materials, case studies, and sales conversations. When a hotel owner is comparing two installers and one has a dedicated page about solar for hotels with hospitality-specific ROI calculations, the specialist wins almost every time.
