Outsourcing lead generation in the UK: the buying detail

Most pages on this topic stop at a list of companies. The decision actually turns on four things: who owns the data, how qualification is defined, what happens when a meeting does not happen, and whether pricing is per lead, per meeting or retainer.

Per lead versus retainer

Retainers suit long programmes with a proven cost per meeting. While you are testing, pay-per-lead keeps your risk at the price of the lead itself: our B2B leads run from $200 to $1,000 depending on the seniority of the role and the tightness of your criteria, with first leads inside 48 hours of campaign approval.

UK coverage and calling hours

We dial UK business hours from our London operation and US hours from our US team. Direct dials are verified before dialling starts, and any campaign that touches consumers is screened against the Telephone Preference Service.

What outsourcing should hand you

A verified contact, the qualification answers from the conversation, the agreed next step with date and time, and a call note the same day. If a booked prospect does not show, we replace them.

Questions to ask any provider on this list

Where does the data come from and when was it verified? What exactly is billed as a lead? What is the replacement policy? Who writes the script, and can you hear real call recordings?

Pricing, delivery and replacement

Pricing on our B2B work runs from $200 to $1,000 per lead depending on how hard the role is to reach and how tight the qualification criteria are. First leads normally land within 48 hours of campaign approval. If a booked prospect does not show up to the meeting, we replace them. We call through UK and US business hours — UK +44 20 7183 3436, US +1 650 278 4421.
