Cold calling services in London: AI agents from 12p per connected minute.
Instead of hiring a London telemarketing agency on a day rate, upload your lead list and let an AI agent phone it for you. Every call is transcribed and recorded, and you pay only for connected minutes.
Why London businesses need cold calling services
London is the largest B2B market in the UK. Financial services firms in the City and Canary Wharf, tech startups across Shoreditch and King's Cross, professional services practices in the West End, construction contractors tendering on commercial builds, property developers and agents, and hospitality operators running restaurants, bars, hotels and venues across every borough — all of them rely on reaching new prospects by phone.
Traditional telemarketing companies in London charge a daily rate, typically with a minimum number of days or a monthly retainer. For a small business testing a new sector or a founder making early sales, that commitment is hard to justify. An AI calling agent removes the retainer and lets you pay only for the minutes you actually use.
How AI cold calling works for London businesses
You upload a list of the London prospects you want to reach — corporate offices, property firms, trade businesses, or any B2B contact across the capital. FoxEra's AI agent (Cass, Alex or Andrea) phones each one, introduces your business, and asks the qualifying questions you set.
Every call is recorded and transcribed. The agent logs who answered, what they said, and whether they showed interest. You review the transcripts and follow up the warm leads yourself, with the full context of what was discussed.
Calls cost from 12p per connected minute with no subscription and no monthly fee. New accounts start with £7 of free calling credit so you can run a test campaign before spending your own money.
London sectors that benefit most
London's strongest industries are well suited to outbound calling:
- Financial services — accountancy firms, IFAs, insurance brokers and fintech companies prospecting corporate clients across the City and beyond.
- Tech startups and SaaS — early-stage companies that need outbound sales without hiring a full-time SDR. Read about AI as an SDR alternative.
- Professional services — law firms, recruitment agencies, consultancies and marketing agencies reaching new accounts.
- Construction and property — subcontractors chasing main contractor work, developers sourcing suppliers, and agents calling landlords.
- Hospitality — suppliers and service companies calling restaurants, bars, hotels and venues across every London borough.
- Creative and media agencies — studios and production houses prospecting brand and marketing teams.
If your prospects have a phone number and a reason to listen, AI calling can reach them. Read more about AI cold calling for B2B sales.
AI calling vs a London telemarketing agency
A traditional telemarketing company in London gives you a human caller working from a script you approve. That works, but it comes with overheads that hit small businesses hard:
- Cost — from 12p per connected minute instead of a daily or weekly retainer that can run to hundreds of pounds before you see a result.
- Transparency — every call is recorded and transcribed so you know exactly what was said, not a summary written by the caller.
- Speed — upload a list and start calling the same day. No onboarding meetings or briefing sessions.
- No commitment — no contract, no subscription, no minimum spend.
The agent handles the volume. You handle the relationships with the warm leads it finds. For a detailed comparison, see AI cold calling vs manual calling.
Building your London calling list
A good list is the difference between a productive campaign and wasted credit. For London prospects, start with Companies House searches filtered by SIC code and registered office postcode, local trade directories, council supplier lists, and commercial property listings.
London's density means you can be specific. Filter by borough, sector, or company size so the AI agent's script matches who it is calling. Organise your leads into folders by prospect type so you track which group converts best and adjust between campaigns.

Connect your AI assistant to manage London campaigns
If you use ChatGPT, Claude, Cursor or another AI assistant, you can connect it to FoxEra and manage your London outreach without logging into the dashboard. Your assistant can add leads, choose the calling agent, preview the campaign cost, and launch it after you approve.
This is useful for busy founders who want to set up a campaign in the morning and check results that evening. Nobody is phoned without your explicit approval, and every action is logged. See the developer guide or read how to connect ChatGPT to cold calling.
