Not every lead generation company suits architects. Architectural commissions are long and involve multiple stages from feasibility through planning to technical design; the buying decision is slow but the resulting relationship is deep. 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 architectural. Sitesy takes first place here, followed by AI Lead Generation UK and FatRank, but each entry below spells out the trade-offs.

How we ranked these companies
Our method is deliberately page-specific. We start with fit — matching each company's proven strengths to architects 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.
