If you want a lead generation agency, the first question is not simply who can bring the most enquiries. It is who can help bring the right enquiries into a process your team can handle. Without that distinction, a campaign can look successful while creating a lot of unsuitable calls.
When choosing a lead generation agency in London, I would make customer fit, source transparency and sales handover central to the discussion. Compare what the supplier will do, what your staff must do and how the outcome will be checked. That is a more useful foundation than a promise of volume.

Write a commercially useful brief
Explain the service and customer you want to acquire. Include coverage, capacity and any practical condition that affects whether the work is worthwhile. A business serving selected London areas has different requirements from one selling a national B2B service.
Choose the next customer action clearly. A quote request, site survey and booked consultation represent different stages. The agency should explain why its offer and form suit that stage rather than use one generic lead process for everything.
I would also describe what currently happens after submission. Who responds? Which questions are asked? When is a proposal prepared? The agency needs this context if it is expected to help improve customer outcomes rather than only deliver contact records.
Give each supplier the same brief. This makes it easier to compare scope and reveals which proposals have been shaped around your actual starting point.
Define the lead standard
Agree service fit, location, contact details and useful timing information. Specify how duplicates, existing customers, job enquiries and requests outside scope are treated. If paying per lead or appointment, clarify the acceptance milestone and any replacement process.
Ask where enquiries come from and what prospects are told before submitting. A purchased contact record and an inbound request are not equivalent. Source transparency helps your team choose an appropriate first conversation and contact method.
Check the sales handover
Verify that the original answers, source and timestamp reach your CRM. Assign an available owner and a next action. Test the process with labelled records, including the fallback for an unavailable closer.
Ask how poor-quality feedback changes the campaign. Your sales team should record useful loss reasons, while the agency should inspect offer, targeting and page design. Read lead qualification and website-to-sales handover.
Compare cost and control
Separate management, advertising, setup, software and sales effort. Compare accepted lead cost with customer acquisition cost and contribution. A high volume of inexpensive enquiries can be costly if few are suitable or reachable.
Confirm ownership of advertising accounts, pages, creative deliverables and customer records. Ask about contract length, cancellation notice and exit handover. Verify actual supplier details; a London address or location claim does not by itself establish capability.
Agree a test and review process
Set the scope, assumptions and reporting definitions before launch. Use a review period that allows opportunities to mature. Ask for reporting that shows enquiries, conversations, appointments and customers, with open outcomes clearly labelled.
Use lead generation pricing models and agency selection questions for a consistent comparison. DIL’s customer acquisition plan can help frame the offer, channel and follow-up requirements for your business.
The questions behind a pay-per-lead offer
Imagine a supplier charges for every lead that meets an agreed definition. Before signing, clarify that definition. Does it include service fit, location and usable contact details? How are duplicates or existing customers treated? What happens when a record does not meet the agreement?
If the offer concerns appointments, ask whether payment relates to a booking, attendance or a qualified discussion. Those milestones create different expectations. The agreement and reporting should use the same meaning.
Ask where prospects come from and what they are told. An inbound request and a researched contact are not the same level of interest. The salesperson needs to understand the source so the first conversation is appropriate.
Then test the handover. The original answers and source should reach the customer record, an available owner should receive the request and exceptions should have a fallback. Volume is not valuable if the team cannot use it.
At the review, connect cost to suitable conversations and customers, allowing the sales cycle to mature. Include the time spent qualifying requests. A lower supplier fee can still lead to a higher full acquisition cost if the work is mismatched.

Frequently asked questions
Does the agency need a London office?
Not necessarily. Assess relevant understanding, delivery and communication. If local meetings are essential, confirm the actual arrangements.
Should I pay only for appointments?
That model can work when the milestone and qualification rules are clear. Distinguish booked, attended and accepted appointments in the agreement.
What proves that leads are valuable?
Suitable conversations and sustainable customer outcomes, measured consistently. Lead volume alone does not establish commercial value.
