Cost-per-lead is total show cost divided by qualified leads — not total leads — and it's a far more honest measure of trade show ROI than a raw lead count. For UK B2B exhibitions, a qualified lead typically costs £30–150, depending on sector, stand investment and how tightly staff qualify visitors on the day. A show that generates 200 badge scans and 15 qualified leads has a very different real cost-per-lead than the headline number suggests.
What Actually Goes Into Total Cost
Stand hire or build, venue space, graphics, staff time — two people for three days is six person-days of cost, not zero — travel and accommodation. Leaving out staff time and travel is the most common way cost-per-lead gets understated, making a show look more efficient than it actually was.
Qualified Leads, Not Total Scans
Total badge scans include browsers, competitors, and people who stopped for the giveaway — dividing your cost by that number flatters the result and hides a genuinely weak show. Divide by qualified leads instead: visitors who met your basic criteria on budget, timeline or decision-making authority. See our lead capture and qualification guide for how to define "qualified" consistently across your team.
Comparing Cost-Per-Lead Across Channels
Once you have a real cost-per-lead figure, compare it against your other acquisition channels — paid search, outbound, referral — on the same basis. Exhibitions often compare favourably once you account for the quality and specificity of a face-to-face qualified lead, but only if the comparison uses genuinely equivalent numbers on both sides.
Using Cost-Per-Lead to Improve Next Time
A high cost-per-lead isn't automatically a failed show — it might mean the wrong show, understaffing that missed conversations, or a lead capture process that let good leads slip through unqualified. Diagnose which of these it was rather than treating the number alone as a verdict, and feed the answer into your next brief.
Frequently Asked Questions
What is a good cost per lead at a UK trade show?
For UK B2B exhibitions, a qualified lead typically costs £30–150, depending on sector, stand investment and how tightly staff qualify visitors on the day.
Should I calculate cost-per-lead using total leads or qualified leads?
Qualified leads — dividing by total badge scans or business cards flatters the number and hides whether the show actually reached your real audience.
What costs should I include when calculating trade show ROI?
Stand hire or build, venue space, graphics, staff time (including days spent, not just wages), and travel and accommodation — leaving any of these out understates the true cost.
