How Much Does An AI Receptionist Cost In The UK?
A practical look at pricing models, comparison points and costs to watch.

AI receptionist providers use different charging models, including per-minute usage and managed service fees. Compare the included call volume, setup, integrations, support and cancellation terms. This is an informational guide, not a RoofFlow receptionist price list.
The Two Pricing Models
Per-minute / per-call tools
Generic AI phone-agent platforms usually bill by usage: a base subscription plus a rate for every minute of AI talk-time. The advertised entry price looks tiny, but three things inflate it in practice: you pay for wrong numbers and spam calls too; a busy month (say, after a storm) spikes the bill exactly when you're busiest; and the "receptionist" arrives untrained — you write the scripts, set up the telephony and maintain it yourself. For a roofer without a technical bent, that last part is usually the dealbreaker.
Flat monthly managed services
A managed provider may include setup, scripting, phone integration and ongoing support in a monthly fee. Confirm usage limits and any extra charges directly with the provider.
What Actually Drives The Price
- Voice and SMS services use different charging models. Compare current usage charges, setup requirements and support directly with the provider.
- Industry specificity. A receptionist that knows the difference between a flat roof and a fascia repair — and asks the right qualifying questions — costs more to build than a generic message-taker, and is worth more.
- What happens after the call. Message-taking is cheap. Qualification, lead summaries, calendar booking, quote follow-ups and review requests each add value and cost.
- Managed vs DIY. Someone has to write scripts, connect the phone line and fix edge cases. Either you do it (cheaper, slower) or the provider does (dearer, done).
The Comparison Everyone Actually Wants

Hidden Costs To Check Before You Sign
- Check the provider’s current usage limits, setup fees, support and service scope before comparing prices.
- Minimum terms. A 12-month contract on a product you haven't heard working is a red flag. Prefer monthly rolling.
- Per-lead or per-minute overages. Ask what a heavy month costs, not an average one.
- Number ownership. If the service gives you a new number, ask what happens to it when you leave. A system layered over your existing number avoids the problem entirely.
- Cancellation mechanics. Leaving should be an email, not a negotiation.
