Leads contacted within 5 minutes are 8-20x more likely to convert to a booked call than leads contacted after an hour. Speed is the single biggest lever on conversion rate.
Lead response speed is consistently the highest-leverage variable in UK IFA conversion data. Leads contacted within 5 minutes are 8-20x more likely to book a call than leads contacted at 60 minutes, and 100x more likely than leads contacted the next day. Building a 5-minute SLA (via CRM alerts + outbound-ready adviser or BDM) is often the fastest route to doubling client yield from the same spend.
