How to choose a B2B lead generation agency
To choose a B2B lead generation agency, ask ten questions before you sign: whether you can run a paid pilot, whether they have case studies in your sector, who will actually be calling, whether you can hear sample calls, how they define a qualified appointment, what happens when one falls short, what they report on, where the data comes from and how it complies with UK law, who owns the campaign data, and what a qualified opportunity actually costs. The answers separate an agency that sells activity from one that sells outcomes.
1. Can we start with a paid pilot rather than a long contract?
A good agency says yes and tells you what a pilot can and cannot prove in ninety days. An agency that needs a twelve-month commitment before the first call has usually been burned by clients leaving early, and it is worth asking why they left.
2. Do you have case studies in our sector, with numbers?
Ask for the campaign, the period, the result and the basis of the result. "We've worked with lots of businesses like yours" is not an answer. A published case study with a stated period and a stated definition of every figure is. If there is no case study in your sector, a good agency says so and explains what transfers from the sectors it has worked in.
3. Who will be making the calls, and where are they?
Ask whether the callers are employed by the agency or subcontracted, where they sit, and how long they have been doing this. An offshore room reading a script is a different product from a UK-based caller who understands your proposition, and it should be priced and described differently. Ask, too, whether the same people stay on your campaign or rotate.
4. Can we hear sample calls?
Any agency proud of its conversations will play you one. Listen for whether the caller is talking about the prospect's situation or reciting yours. Listen for what happens at the first objection. If you cannot hear a call before you sign, assume you will not like the ones made after.
5. How do you define a qualified appointment?
This is the question that matters most, and there are three kinds of answer.
-
A fixed definition
"a meeting with a decision-maker at a company of 50+ staff". Easy to compare, and easy to game: the definition is written to make the number look good.
-
No definition
"a meeting". Walk away.
-
Criteria agreed with you
the agency drafts qualification criteria for your campaign, in writing, before outreach begins, and every appointment is checked against them. Harder to compare across agencies, and the only version that describes your business rather than theirs.
Whichever answer you get, ask to see it written down.
6. What happens when an appointment cancels or was not qualified?
A blanket "we replace any cancellation" sounds generous and rewards booking meetings that were never going to hold. The more useful answer is a written process: the appointment is reviewed against the agreed criteria, and if it fell short, an agreed action follows. Ask what proportion of their booked appointments actually go ahead, and what proportion go to a proposal. An agency that measures the second number is measuring the thing you care about.
7. What will you report on?
Dials and talk time measure the agency's effort. Decision-maker conversations, qualified opportunities, appointments held and what happened after handover measure your return. Ask for a sample report, and ask whether it reconciles to your CRM or lives in a spreadsheet only the agency can see.
8. Where does your data come from, and how does it comply?
B2B outbound in the UK is lawful under PECR and UK GDPR when done properly: corporate subscribers, a legitimate-interests basis, suppression against the Corporate Telephone Preference Service, identified senders and working opt-outs. Ask where the list comes from, how it is enriched, how suppression is handled across email and phone, and who is the data controller for the campaign data. An agency that cannot answer fluently is a compliance risk carried on your name.
9. Who owns the campaign data, and does it integrate with our CRM?
The list, the contacts, the notes and the outcomes should be yours, delivered into your CRM or in a format you can use, during the campaign and after it. Ask what you keep if you stop. If the answer is "the appointments you already had", the agency is holding your pipeline hostage.
10. What does a qualified opportunity actually cost?
Not the monthly fee, and not the cost per dial or per hour. Divide the total campaign cost by the number of qualified opportunities that met the agreed criteria, then by the number that went to proposal. Ask the agency to show you that arithmetic from a past campaign. It is the only price that can be compared to the value of a customer, and an agency confident in its qualification will show it to you.

FAQ
Questions
How much does B2B lead generation cost in the UK?
Fees vary widely with the model: by the dial, by the hour, by the appointment, or as a monthly retainer. The only comparable price is cost per qualified opportunity - total campaign cost divided by opportunities that met agreed criteria - and a good agency will show you that figure from a past campaign.
What is a good appointment-to-proposal rate?
There is no universal benchmark, and it varies by sector and by the client's own sales process. What matters is that the agency measures it at all. Lets Elevate's largest published campaign ran at 72% over twelve months.
Is B2B cold calling legal in the UK?
Yes, provided the number is screened against the Corporate Telephone Preference Service, the caller identifies themselves and their company, and any request not to be called again is honoured.
Should I choose an agency that guarantees results?
Be cautious. Sit rates, conversion rates and returns depend on your sector, proposition and sales process. An agency that publishes its historical averages with their basis is telling you more than one that guarantees a number.
Lets Elevate answers all ten, and the one most agencies cannot - how many appointments went to proposal - is on our case study pages with its period and its basis. If you would like to put the ten questions to us, we would rather you did that first.
