Every agency page about construction lead generation says the same three things. Leads are the lifeblood. Quality beats quantity. They are data-driven. Not one tells you what a construction lead actually costs.
We will. Below is a real cost per lead from an account we run, the range it moved through, and the campaign that went badly wrong. Then the four channels compared, and the part of construction lead generation almost everyone gets wrong.
On a live account we run, paid social produced 360 leads at an average cost of £4.64 each between June 2023 and July 2026. Within that average the best campaign ran at £2.04 a lead and a traffic campaign ran at £53.13. The average is not the point. The spread is.
The account is The Timber Design Studio, a timber frame design consultancy selling to self-builders, developers and manufacturers. The published figures: 360 leads at £4.64 average cost per lead, 8,260 clicks at £0.20 each, 335,975 impressions, 148,300 people reached, a 2.46 per cent click-through rate.
Three things matter more than the headline. One creative produced 230 of the 360 leads, and we tested 19 variants to find it, which is why a two-week trial tells you nothing. The best single ad ran at £1.97 a lead while driving traffic rather than asking for the enquiry directly ran at £53.13, same product, same audience. The lead form campaign produced 272 of them, so asking inside the platform was the biggest structural decision we made.
Your cost per lead will differ. The shape will not: a wide spread, one creative doing most of the work, and the winner only findable by running the losers.
For most construction businesses the answer is two of these running at once, the slow one building while the fast one pays the bills.
Fastest to start and cheapest per lead in our experience, but the leads are colder because you interrupted someone rather than answering them. Best for volume and for testing message. Stops the day you stop paying.
The most expensive click and the warmest lead, because the person went looking. Organic takes four to six months to build, then costs very little per lead. Paid search is instant and never gets cheaper.
Immediate, predictable, and you are one of four quotes on price. Useful for filling gaps, poor as a foundation, because you are renting a relationship.
The best leads by a distance and the ones you cannot turn on when you need them. Everything above exists because this one is not controllable.
Most construction firms do not have a lead generation problem. They have a lead handling problem, which is cheaper to fix.
A lead answered within an hour converts far better than one answered next morning. Being on site all day is a real constraint, so the fix is an immediate holding response and a fixed time each day to ring back, not a promise to be more responsive.
Four questions on the phone before you spend an evening on a quote: what the job is, roughly where, when they want it, and whether they have had other prices.
Construction decisions take months, and most quotes are sent once and never mentioned again. Two follow-ups, at a week and a month, recover work you already paid to generate.
If you cannot say which channel produced the last ten jobs, you cannot decide what to stop paying for. One spreadsheet column is enough to start.
Cost per lead is the number agencies report because it flatters them. Cost per job won is the number that decides whether the work is worth doing.
The arithmetic is worth doing once. Divide spend by leads for cost per lead, divide leads by jobs won for your conversion rate, multiply the two, and compare that to your margin on an average job.
£160 a job. On a £30,000 build that is nothing, and it will never be the reason the year went badly.
£360 a job, and it looks cheap on the report. Cheap leads that do not convert are the most common way construction marketing budgets get wasted.
Ask any agency, including us, for cost per job. If they can only give cost per lead, they are not tracking far enough down the funnel.
It varies by channel and job size. On a live account of ours, paid social averaged £4.64 a lead over three years, with campaigns ranging from £2.04 to £53.13. Search leads typically cost more and convert better.
Yes, more slowly. The Google Business Profile, service pages, location pages and reviews produce enquiries at very low ongoing cost once established. The method is in our guide to SEO for builders.
Generating more leads into a process that drops them. Fix the follow-up before increasing the budget.
Send us where your last ten enquiries came from and what happened to them. We will tell you which channel is paying, which is flattering the report, and what we would change first. Half an hour, no charge.
For the wider view, the channel-by-channel breakdown is in digital marketing for construction companies, and what we do as a construction marketing agency is on the main page.
