Lead generation companies in London: AI calling from 12p per connected minute.
Most London lead generation firms charge a monthly retainer and deliver leads with little context. FoxEra's AI agent phones your list, qualifies each prospect, and gives you the full transcript so you know exactly who is interested and why.
How London lead generation companies typically work
A traditional lead generation company in London takes on your brief, builds or buys a list of prospects, and reaches out through phone calls, emails, or both. You pay a monthly retainer or a per-lead fee and receive a spreadsheet of contacts who expressed some level of interest.
The problem for many small businesses is that you rarely know what was said to each prospect. You get a name and a "warm" label but no recording, no transcript, and no context for your follow-up call. The retainer keeps running whether the leads convert or not.
How AI lead generation works differently
FoxEra takes the outbound calling part of lead generation and makes it transparent, pay-as-you-go, and entirely under your control.
- You supply the list — upload a spreadsheet of the London businesses you want to reach, or build one using the UK cold calling list guide.
- The AI agent calls — Cass, Alex or Andrea phones each prospect, introduces your business, and asks the qualifying questions you set.
- You get full transcripts — every call is recorded and transcribed. You read exactly what was said and decide which leads are worth your time.
- You pay per minute — from 12p per connected minute with no subscription, no retainer and no minimum spend.
New accounts start with £7 of free calling credit so you can run a test campaign before committing your own money. See full pricing details.
London sectors suited to AI lead generation
AI calling works best for B2B prospecting where the goal is to identify who is interested and pass them to a human for the relationship. The London sectors with the strongest fit include:
- Financial services — accountancy firms, insurance brokers, wealth managers and fintech companies prospecting corporate clients across the City.
- Tech and SaaS startups — early-stage companies that need outbound sales but cannot justify a full-time SDR. See AI as an SDR alternative.
- Professional services — law firms, recruitment agencies, consultancies and training providers reaching new accounts.
- Construction and property — subcontractors sourcing main contractor work, suppliers calling site managers, and agents prospecting landlords.
- Hospitality suppliers — companies selling equipment, food, drink or services to restaurants, bars, hotels and venues.

Cost of lead generation in London: agency vs AI
London lead generation agencies typically charge a monthly retainer or a per-lead fee. You may spend hundreds of pounds before you have enough data to know whether the campaign is working.
With FoxEra, you start with £7 of free calling credit and pay from 12p per connected minute after that. A test campaign of fifty calls at an average connected time of two minutes costs a fraction of a single day's retainer with a London agency.

What you get after each campaign
After every campaign, you have a complete record of every call your AI agent made:
- Recording — listen to any call to hear exactly how the prospect responded.
- Transcript — read the full conversation, word for word. Learn how to read a cold call transcript.
- Outcome tags — each call is tagged so you can filter for interested, not interested, callback requested, and so on.
- Follow-up ready — the warm leads go straight into your follow-up workflow. Read about cold call follow-up sequences.
This is the transparency that most London lead generation companies do not offer. You make the judgement on lead quality, not the agency.
