AI voice agents that answer London callers properly, in their language, at any hour.

Codeeo handles AI voice agent development London firms can put on a real phone line: agents that pick up, understand what the caller needs, check your systems and either finish the task or pass a clear summary to a person. We build them for regulated City firms, lettings agencies, restaurants and clinics, where a missed or mishandled call costs a client, a booking or a compliance record.

Our team of 80+ works from Dubai, Riyadh and Karachi and runs London projects remotely, with discovery, demos and reviews held by video call. You get a working agent on your own numbers and accounts, not a demo that only sounds good in a sales meeting.

Built for
Financial services firms, lettings and estate agents, hospitality groups and private clinics across London.
Typical timeline

What a London voice agent can do

Built around the calls London businesses actually receive.

A phone call to a London business can come from a fund client in Singapore, a tenant in Croydon with water coming through the ceiling, or a visitor near Leicester Square trying to book a table for six. Each one wants a different thing, and each one hangs up quickly if the line feels robotic or slow. We start with recordings or logs of your own calls, group them by intent, and decide which ones an agent should complete, which it should triage, and which must go straight to a person. That split matters more in London than almost anywhere in the UK, because so many firms here sit under the Financial Conduct Authority, handle client money or deal with people who may be vulnerable. The features below are the ones we most often build for London operators. Few projects need all of them at once, and the first release is usually the two or three call types that eat the most staff time.

Explain your project
  • Multilingual first response

    London callers speak dozens of languages. The agent can detect the caller's language from the first sentence and continue in it where the speech models perform well, falling back to English with a polite handover when they do not. We test every language with native speakers before it goes live, rather than trusting a vendor's list.

    International clients and visitors are understood on the first try.

  • Recording and retention for regulated firms

    FCA rules require certain investment firms to record relevant telephone conversations and keep them. We design the agent so every call, transcript and decision is stored in a place you control, with retention periods you set and an audit trail compliance staff can search. Recordings can be exported in a standard format whenever a regulator or client asks for them.

    Your compliance team can find any call without asking engineering.

  • Caller verification before any detail

    Before the agent reads out a balance, a tenancy end date or an appointment, it checks who is calling using the questions your security policy already allows, such as a date of birth plus a reference. Failed checks end politely with a route to a person, and repeated attempts on one account raise an alert to your fraud or operations team.

    Personal details are only shared with the right caller.

  • Vulnerability cues and human handover

    Consumer Duty expects firms to treat customers in vulnerable circumstances fairly. The agent listens for signs such as distress, confusion or mentions of bereavement and hands the call to a trained person with the context attached, instead of pressing on with a script. Each flag is logged, so you can later review how those calls were handled.

    Sensitive calls reach a human fast, with nothing to repeat.

  • Out-of-hours lettings triage

    For agents managing rented homes across the boroughs, the voice agent takes maintenance calls at night, asks the questions your property managers would ask, separates leaks, gas smells and lockouts from routine repairs, and alerts the on-call contractor only when it is truly urgent. Tenants receive a job reference by text straight away.

    Emergencies get a response; routine jobs wait for the morning.

  • Restaurant and venue bookings

    West End and City restaurants lose bookings when the phone rings during service. The agent checks live availability in your reservations system, takes party size, dietary notes and special occasions, confirms by text and handles changes or cancellations without anyone leaving the floor. Requests for very large parties go to a manager.

    Bookings are taken while the team is busy serving.

  • Card details kept out of the conversation

    When a caller pays, the agent passes them to a secure keypad capture step run by a PCI DSS compliant payment provider, so card numbers are never spoken to the model, transcribed or stored in your recordings. The agent rejoins once the provider confirms the result, reads back the receipt reference and emails a copy to the caller.

    Payments by phone without card data in your transcripts.

  • CRM and case system lookups

    The agent verifies the caller against your records, reads back the status of a matter, policy, application or order, and logs a summary against the right client in Salesforce, Dynamics 365 or whichever system your teams already use. Where a request needs a person, the summary is ready before anyone opens the file.

    Every call leaves a tidy note in the system of record.

  • Callbacks across time zones

    Many London firms serve clients in New York, Dubai and Hong Kong. The agent offers a callback at a time that suits the caller's own clock, books it into the right adviser's calendar and confirms it by email or text. If the adviser is away that day, the booking moves to a named colleague.

    Overseas clients are called back when they are awake.

  • Call quality dashboard

    A dashboard shows containment, handover reasons, average handling time and the questions the agent could not answer, so you can see where the knowledge base needs work before callers notice the gap. Figures can be split by line, call type and hour of day, which helps you decide which flow to automate next and which to leave with people.

    Weak spots show up in data, not in complaints.

Who this suits

Four London teams that get the most from a voice agent.

A voice agent pays off where calls are frequent, repetitive in shape and costly to miss. In London that usually means teams with high call volumes and strict rules about what can be said. It is a weaker fit where nearly every call is a complex negotiation or a complaint, and we will say so during discovery rather than sell you an agent that frustrates callers. These are the four situations we see most often, and what changes in the build for each.

01

Wealth managers, brokers and insurers in the City and Canary Wharf

Client service lines in these firms carry a heavy share of routine questions: valuations, document requests, address changes, payment dates. A voice agent can handle identity checks and status questions while advisers focus on advice. The design work goes into what the agent must never say, such as anything resembling a personal recommendation, and into making sure recordings meet your FCA obligations. Identity checks follow the same steps your staff use today, and anything the agent is unsure about goes to an adviser with the reason noted.

Your compliance team signs off the scripts before launch.

02

Lettings and block management agencies

Tenants and leaseholders ring at all hours, and most calls are about repairs, rent dates or viewings. The agent takes the detail once, raises the job in your property management software and texts the tenant a reference. Urgent safety issues are escalated to a person by phone, never left in a queue overnight. Landlords can be updated automatically when a job is raised on their property, and transcripts give you a clear record if a disagreement about a repair later reaches a deposit scheme or a tribunal.

03

Restaurant groups and venues in the West End

Busy sites cannot staff a phone during service, and a ringing line at seven in the evening is lost revenue. The agent handles bookings, opening hours, allergen questions it has been given approved answers for, and private dining enquiries, which it passes to your events team with every detail captured. Deposit and cancellation policies are read out exactly as written. On quiet afternoons the same agent can return calls to guests who left a message and confirm group bookings a day ahead when guests asked for a reminder.

Allergen answers come only from text you approve.

04

Private clinics and diagnostic providers

Clinics around Marylebone and the wider city field booking, rescheduling and preparation questions all day. The agent books and moves appointments, sends preparation instructions and routes anything clinical to a nurse or receptionist. Health information is special category data under UK GDPR, so storage, access and retention are agreed with you before any build starts. The agent never offers a diagnosis or comments on symptoms. If a caller describes something that sounds urgent, it tells them to call 999 or NHS 111 as appropriate and alerts your clinical team.

How a London voice agent goes from first call to live line.

  1. 01Listen to real callsWe review a sample of your recordings or call logs by video call with your team, sort them by intent and pick the calls that should be automated first. We also mark the ones that never should be.
  2. 02Write the rulesTogether we set what the agent may say, what it must never say, when it hands over and how it introduces itself, with compliance and legal reviewers involved early. Nothing is left to the model's judgement.
  3. 03Connect the systemsWe build the lookups and write-backs into your CRM, booking or property software, and connect the agent to your numbers through your telephony provider or a SIP trunk. Each link is tested on its own first.
  4. 04Test with London voicesScripted and unscripted test calls with a wide mix of accents, background noise from trains and kitchens, and every handover path, until the error rate is acceptable to you. Speakerphone calls are included.
  5. 05Soft launchThe agent takes a share of calls, or only out-of-hours calls, while your team reviews transcripts daily and we adjust prompts, answers and routing. Your team can take the agent off the line instantly if anything looks wrong.
  6. 06Tune and widenOnce results hold, we add call types, languages or outbound callbacks, guided by the dashboard rather than guesswork. Each addition goes through the same testing as the first release, and your team signs it off before any caller hears it.

Technology

What we build this with.

Speech recognition, a large language model, natural text to speech and telephony, chosen for latency, accuracy on London accents and where your data must live. We prefer components you can swap later, so you are not tied to one vendor.

What London firms ask before building a voice agent.

It depends on the call types and integrations, and we agree it after discovery.

The main factors are how many kinds of call the agent must handle, how many systems it must read from and write to, how many languages it speaks, and how much review your compliance or legal team needs. A single call type with one booking system moves faster than a regulated client line with identity checks and recording rules. We write the scope and the dates down after we have heard your calls, before any build starts. Cost follows the same factors, along with expected call volume, because speech and model usage are billed per minute by the providers you choose.
