Frequently Asked Questions

How much does an AI voice agent cost per month?

A custom AI voice agent typically costs GBP 200-500 per month for hosting and API usage, plus a one-off build cost of GBP 5,000-15,000 depending on complexity. Off-the-shelf solutions range from GBP 50-500 per month but offer less customisation and lower automation rates.

How long does it take to deploy?

A basic voice agent for appointment booking or FAQ handling takes 2-3 weeks. More complex agents with CRM integration, custom workflows, and multi-language support take 4-8 weeks. We deploy in stages so you see value from week one.

Will customers know they are talking to AI?

Modern voice agents sound natural and conversational, not robotic. Most callers cannot tell the difference for routine interactions. We recommend transparent disclosure that the caller is speaking with an AI assistant, which most customers appreciate for faster service.

What happens when the AI cannot handle a call?

The agent detects when a conversation exceeds its capability and transfers to a human agent with full context. You set the escalation rules: specific topics, customer sentiment, VIP callers, or any criteria that matters to your business.

Do I need to replace my phone system?

No. AI voice agents integrate with your existing phone system via SIP trunking or call forwarding. No hardware changes required. Setup typically takes a single afternoon.

What about data privacy and GDPR?

All call data is processed and stored in compliance with UK GDPR. Calls can be recorded with consent, transcripts are encrypted at rest, and you retain full ownership of all data. We can deploy on UK-based infrastructure if required.

Can the AI agent book appointments in my calendar?

Yes. The agent integrates with Google Calendar, Microsoft 365, or any calendar system with an API. It checks availability in real time, books appointments, sends confirmations, and handles rescheduling.

What is the payback period shown in the calculator?

The payback period estimates how many months of savings it takes to recoup a typical GBP 8,000 build cost. Most businesses achieve payback in 2-6 months depending on call volume and cost per call.
