A practical framework for UK business owners on pricing paid leads, running a small controlled test, and scaling only what converts into paid work.
Most UK business owners shop for leads the wrong way round. They ring three suppliers, compare price per lead, and pick the middle one. That tells you nothing about whether a lead is good value, because the only number that matters is what a won customer is worth to you. Before you look at a single quote, calculate your average job value, your gross margin, and your realistic conversion rate from enquiry to signed job.
Take a removal company with an average job of £1,400 and a 35% gross margin. That is £490 of gross profit per job. If you convert roughly one in four enquiries into a booked move, you can afford up to about £120 per lead and still make money, leaving headroom for survey time and van fuel. A solicitor with a £3,000 probate instruction at 50% margin has a far higher ceiling. Same lead, very different value.
| Sector | Typical average job value | Assume 30% gross margin | Conversion (enquiry to job) | Break-even cost per lead |
|---|---|---|---|---|
| Removals | £1,400 | £420 | 1 in 4 | £105 |
| Probate (solicitor) | £3,000 | £1,500 | 1 in 5 | £300 |
| House clearance | £600 | £240 | 1 in 3 | £80 |
| Small building job | £4,000 | £800 | 1 in 6 | £133 |
| New business (accountancy) | £1,200/yr | £720 | 1 in 5 | £144 |
That table is a starting point, not gospel. Your real numbers will differ, and you should replace the assumptions with your own closed-job data within a month. The discipline of writing the ceiling down before you buy is what stops you overpaying for volume you cannot convert.
Suppliers will push monthly bundles because predictable revenue suits them. Resist for the first month. Buy a small, fixed batch, ideally 20 to 30 leads, and treat it as a paid experiment with a defined budget you are willing to lose. The purpose is not to make money in month one; it is to learn your true conversion rate and your true cost per won job before you scale.
Set the test up properly. Brief whoever answers the phone on how to log each enquiry: date received, time to first contact, whether it was in your service area, whether the budget matched, and the final outcome. Without outcome tracking you are just guessing. A lead that never answers is not the same as a lead that answered, got a quote, and chose a cheaper competitor, and the two demand different responses.
At the end of the test, divide total spend by the number of jobs you actually won. If that figure sits comfortably below your gross profit per job, you have something worth scaling. If it does not, you have saved yourself a costly annual contract.
Be sceptical of any supplier who leads with the word exclusive as if it settles the argument. What matters is whether the enquiry is qualified: is the person real, is the work in your area, is the timing genuine, and is there enough information for you to prepare before you call? A shared lead that is well qualified and reaches you instantly is often worth more than a vague exclusive one.
Ask suppliers specific questions rather than accepting marketing language. How is the lead generated? What information is captured? How quickly is it passed to me? How many other firms receive the same enquiry? What happens if the contact details are wrong? A supplier who answers those clearly and consistently is worth testing; one who deflects is telling you something useful too.
| Question to ask | Good answer | Warning sign |
|---|---|---|
| How is the lead generated? | Specific source and capture method | Vague talk of a network or partners |
| How many firms get it? | A clear number, e.g. exclusive or max 3 | Refusal to say |
| How fast is it delivered? | Within minutes, ideally by email and SMS | Next-day or weekly batches |
| What if details are wrong? | Written credit or replacement policy | No policy at all |
The single biggest destroyer of lead ROI in UK small businesses is slow response. If a prospect enquires at 7pm and you call at 10am the next day, you are competing against firms who rang within ten minutes. In removals, probate and building work, the first competent caller wins a disproportionate share of jobs, because the customer is anxious and wants reassurance immediately.
You do not need expensive software to fix this. You need a rota. Decide who owns incoming enquiries during working hours, who owns evenings and weekends, and what the maximum acceptable response time is. Fifteen minutes during the day and a first thing next morning callback for out-of-hours enquiries is achievable for most firms with two or three staff. Write it down and hold people to it.
If you cannot meet a reasonable response standard, do not buy leads yet. You will pay for enquiries and lose them to faster competitors, then conclude wrongly that paid leads do not work.
Cost per lead is a vanity number. A £40 lead that converts at one in three is cheaper than a £15 lead that converts at one in fifteen. The only figure that governs whether you should keep buying is cost per won job, measured against gross profit. Build a simple spreadsheet and update it weekly; you do not need a CRM to start, though one helps once volume grows.
Include the hidden costs. Staff time on the phone, site surveys that go nowhere, and travel to quotes all eat into margin. A removal company that sends a surveyor to ten enquiries and wins four has absorbed six wasted visits. That is real money. Add an estimate of your own time per lead to your cost per won job and the picture becomes honest, sometimes uncomfortably so.
Once you know your cost per won job and it sits well below gross profit, scale carefully in increments rather than doubling overnight. Doubling volume often doubles the workload on the same two people, response times slip, and conversion drops, making the leads look worse than they are. Increase by 25-50% and hold there until response times and conversion are stable again.
Review monthly and be willing to cut. If a supplier's leads convert at half the rate of another's, reduce that supplier's volume regardless of how good the account manager is. Segment by source, by sector and by area, because a lead type that works brilliantly in one postcode may be poor in another. Prune ruthlessly and reinvest the savings in the sources that reliably produce signed jobs.
Finally, remember that leads are a tap, not a tap-dance. The businesses that win consistently are the ones with a boring, repeatable process: fast response, a proper qualification call, a clear quote, and disciplined follow-up. Get those right and paid leads become a predictable input to a predictable pipeline. Get them wrong and no supplier, however good, will save you.

Start your free 7-day trialExplore Business LeadsIt depends entirely on the average job value in your sector, not on what a supplier says is 'market rate'. Work backwards: if your average job is worth £2,000 at 40% gross margin (£800), you can afford a lead cost of perhaps £80-£160 provided you convert roughly one in five. Always calculate your ceiling price before you compare quotes.
Treat the first 20-30 leads as a test, not a verdict, and track every one to a closed outcome. Below about 20 leads, one unusually good or bad enquiry swings your conversion rate wildly and tells you nothing reliable. Judge on closed jobs and gross profit, never on how promising the enquiries felt on the phone.
Shared leads are cheaper per enquiry but you are racing other firms to the same prospect, so speed and a strong opening script matter far more. Exclusive leads cost more but give you room to sell properly. Neither is automatically better; the right choice depends on whether your team can respond within minutes and whether your margins can absorb the higher unit cost.
Buying volume before proving conversion. Owners often commit to a monthly bundle to get a discount, then discover their follow-up process cannot cope and half the enquiries go cold. Start small, measure to closed job, and only increase volume once you know your true cost per won customer including staff time.
