Not every lead generation agency suits renewable energy installers. Commercial renewable projects have long sales cycles from initial feasibility through grid connection application to installation, often spanning six to eighteen months for larger sites. 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 agencies on their fit for renewable energy. PromoSEO takes first place here, followed by FatRank and LLM Leads, but each entry below spells out the trade-offs.

How we ranked these agencies
Our method is deliberately page-specific. We start with fit, matching each company's proven strengths to renewable energy installers and how they convert, then factor in pricing model, exclusivity and the breadth of channels on offer. Companies that carry more of the risk, or guarantee exclusivity, tend to score well. The result reads differently here than on any other page, by design.
