Best AI cold calling software UK (2026)

There isn’t one, and any list naming a single winner is guessing on your behalf. Decide first whether you are buying a developer platform, a calling suite or a finished product — that removes five of the eight immediately.

Re-checked 2 October 2026: only FoxEra Calls prices in pounds throughout. Synthflow, Bland, Vapi, Retell, Orum, Dialpad and JustCall all publish in US dollars.

Re-checked 2 October 2026: Bland $0.14/min at entry, Retell a $0.07–$0.31/min range, Vapi $0.05/min for hosting with model costs on top, JustCall quotes a volume-based rate through its own calculator rather than a flat published figure, FoxEra Calls 21p per connected minute.

No. Synthflow publishes a $30,000 annual floor and nothing more granular. Dialpad sells its AI agent as a credit pool through sales. Orum’s own pricing page publishes no number — it is priced by package and seat count through a request-pricing form.

Usually not. Platform fees, model costs passed through separately, minimum concurrency charges and whether ringing time is billable all move the real number more than the headline rate does.

No. It handles first contact and qualification. The prospect who says yes still needs a person for the actual sales conversation.

AI cold calling software uses a configured voice agent to conduct structured first-touch calls, capture outcomes and connect suitable prospects to the next step in a sales workflow. It works an uploaded lead list automatically rather than a person working a dial sheet.

Yes. The Privacy and Electronic Communications Regulations 2003 (PECR) do not ban cold calling — they attach conditions: screen against the Telephone Preference Service and the Corporate TPS, honour your own suppression list, and allow your number to be displayed. Full detail, quoted from PECR and the ICO’s own guidance, is on our is cold calling legal in the UK page.

Not under UK law. Checked against PECR regulations 19 and 21 and the ICO’s telephone marketing guidance: no UK rule requires a caller to state it is an AI. UK law requires you to say who is calling, allow your number to display, and give a contact address. The EU AI Act is different: Article 50(1) of Regulation (EU) 2024/1689 requires systems that interact directly with people to disclose they are AI, in force from 2 August 2026. Full detail on our AI disclosure rules page.

It dials automatically from an uploaded lead list. FoxEra Calls’ published offer covers the AI agent, dialling, transcription, CRM logging and call recording at 21p per connected minute, so the call, its transcript and its outcome land in the same place without manual data entry.

Yes. FoxEra Calls works your lead list, has the first conversation, and logs every word to your CRM, then follows up by email — so the outcome, the transcript and the next action are captured without anyone copying notes between systems.

Yes. ICO guidance says the rules are the same as for calls to individuals. Sole traders and some partnerships register with the TPS; companies, other partnerships and government bodies register with the CTPS — so a B2B list needs screening against both registers, not just one, plus your own do-not-call list.

Not automatically. ICO guidance says data protection law and PECR do not necessarily prevent it, but a page being public does not make the information free to use for marketing — you still have to tell people you hold their details, say what you will do with them, and check the use is fair, lawful and not unexpected.

Regulation 24 of PECR 2003 requires the caller's name to be given on a live marketing call, plus an address or a free-to-reach number if the person asks for one. Regulation 21(A1) separately requires the caller ID to be shown, or a reachable number given instead. Neither requires the agent to say it is an AI.

It can follow approved responses within a defined call, but it is not the right caller for live discovery, unusual objections, bespoke commercial questions, or a conversation that has to change direction on judgement. Use a person for that; use AI calling for structured, repeatable first-touch work.

No. There is no monthly seat subscription on the pay-as-you-go offer — teams top up calling credit as needed and pay 21p per connected minute, whatever the team size.

Yes. A new FoxEra Calls workspace can start with 7 pounds of free calling credit, no card required, enough to hear the AI on a real call before deciding.

Yes. Teams can find leads inside the product before starting a calling campaign, rather than importing a list from somewhere else first.

Every call is logged word for word against the contact in the CRM, so the transcript is there without extra setup or cost. Whether you also keep an audio recording, and the notice and consent that goes with it, is your own decision.

It depends on the task. For high-volume introductory calls — dialling, introducing, qualifying and logging — an AI agent handles the repetitive work while a person focuses on the warm leads it produces. For complex consultative selling a person is still better. Full detail on our does AI cold calling actually work page.

With FoxEra Calls there is nothing to install, no contract to sign and no onboarding to wait for. With a list of contacts ready, an account can be created and a first campaign launched within minutes — see how fast you can start.

Yes. On FoxEra Calls the script is written in plain English before any calls are made. The agent follows the wording, the introduction and the qualifying questions exactly as set, rather than a fixed vendor pitch — more on using your own script.

Not with FoxEra Calls. It runs entirely in a web browser, with nothing to download or install — a real difference from the developer platforms in this comparison, which assume someone on your side can write code. Full answer on our technical skills page.

There is no verified public benchmark comparing hang-up rates between AI and human cold calls. Some people hang up on any cold call; a short opening, a relevant offer and a clean list reduce it for both — see our honest answer.

Some people notice, some do not. FoxEra Calls’ voice is natural and conversational and the agent confirms it is AI if asked directly — what matters more than detection is whether the call is relevant to the person receiving it. More on our robot-sounding page.

Yes. On FoxEra Calls a campaign can be cancelled at any time from the dashboard or by asking the AI assistant. Calls already connected finish naturally; leads not yet dialled stay in the list and are not charged — see stopping a campaign.

Not with FoxEra Calls. There is no contract, no minimum term and no subscription — calling credit is bought and used when wanted, and nothing is charged if a team stops. Full detail on our cancelling any time page.

Not on FoxEra Calls. Voicemails, busy signals and unanswered rings are not connected minutes and are not charged — the per-minute rate above only applies once someone picks up. See billing on unanswered calls.

On FoxEra Calls the agent follows the approved script and does not invent claims or commit to anything outside it. If asked something it cannot answer, it says so rather than guessing — see our full answer.

On FoxEra Calls a campaign needs the exact confirmed headcount and a separate approval before anyone is phoned — an AI assistant connected to the platform cannot bypass that step. More on our safety controls page.

None of the eight platforms compared here replace a salesperson. AI cold calling handles structured, repeatable first-touch work; a person is still the better buy for a conversation that needs judgement, discovery or a relationship. Full detail on what you give up.

FoxEra’s AI agents sound natural, but they do not pretend to be human if asked directly. The script you approve determines how the call is framed — transparency builds trust rather than damaging it. Full detail on our reputation risk page.

Every call is recorded and transcribed. You have the full record of what was said, when, and to whom — letting you respond to any complaint with evidence rather than guesswork.

No. Every campaign is built from a confirmed list and needs your approval. If you want to retry unanswered leads, you create a new campaign with those contacts. More on calling the same person twice.

There is no hard limit in the software, but Ofcom’s persistent misuse guidelines mean you should not keep calling someone who has declined or who consistently does not answer. Every attempt is logged.

No. Every campaign needs a confirmed headcount and a separate approval step before anyone is phoned. This is enforced server-side and cannot be bypassed from any client. More on our outbound calling guardrails page.

No. The same rules apply to both connection methods and to the dashboard: confirmed headcount, separate approval, calling hours, scoped access and full logging are enforced on the server regardless of how a campaign is started.

The API costs (Twilio, OpenAI, text-to-speech) vary by volume, but the real cost is development time — typically weeks of work before the first call sounds right, plus ongoing maintenance. FoxEra costs from 21p per connected minute with no build required. Full comparison on our build vs buy page.

Yes. The API accepts leads in standard formats, so migrating a contact list is straightforward, and you can run both systems in parallel during a transition.

An AI assistant can find and shortlist leads, and a separate AI calling agent can phone them — but you approve the campaign before anyone is called. There is no fully automatic dial-without-oversight system. More on AI that finds leads and calls them.

Yes. Business-to-business cold calling is legal in the UK regardless of how the list was sourced, but it should still be screened against the TPS and CTPS registers for sole traders and individuals.

Any assistant that supports MCP, including ChatGPT, Claude, Cursor and DeepSeek-based agents. REST API keys also work with tools like n8n, Make or your own code. See our scheduling a campaign with your AI assistant page.

FoxEra enforces UK calling hours automatically. If the requested time window falls outside permitted hours, calls will not start until they are allowed.

No. FoxEra is pay-as-you-go with no subscription and no monthly fee — you pay from 21p per connected minute and nothing when you are not calling. More on what 100 AI calls cost.

You top up with whatever amount you like. There is no subscription and no minimum — if you stop, there is nothing to cancel, your balance simply stays until you use it. See the free trial page.

It can suit a team with variable campaign activity that wants to test without paying a monthly licence for every user. More on AI cold calling for small teams.

Export it with names and phone numbers, upload it to FoxEra, and run the campaign. If your AI assistant already holds the list, connect it via the MCP server and let the assistant handle the upload.

Every call is transcribed and logged with the outcome. You can read the transcript, listen to the recording, and see whether the prospect asked for a quote, said to call back, or was not interested — focus your time on the warm responses.

Yes. Ask your assistant to revise the script based on call transcripts or your own observations, then submit the updated version and approve a new campaign with the revised pitch. More on writing a pitch with ChatGPT.

That depends on the server. FoxEra’s MCP server requires your approval before anyone is phoned, logs every action, and lets you revoke access at any time — always check what a server can do before connecting. More on what an MCP server is.

Yes. FoxEra Calls has a documented REST API (OpenAPI 3.1 at app.foxera.co.uk/api/public/openapi.json) and a remote MCP server at app.foxera.co.uk/mcp for AI assistants such as Claude, ChatGPT and Cursor. See the developer docs.

Industry benchmarks from sources like Cognism suggest B2B connect rates of roughly 5% to 15%. Your actual rate depends on data quality, industry and time of day. More on how many leads you need.
