AI Receptionist Hidden Fees UK — The £19/Month Trap
Updated September 2026 · 8-minute read

The £19 trap — how it works
You see an ad: "AI receptionist from £19 a month!"
Sounds like a bargain. A tenth of what a human would cost.
Then the first bill arrives and it's £87.43.
You call support. They explain the £19 covers 30 call minutes. Every extra minute is 49p. Your calls averaged 3 minutes each. You got 45 calls this month. That's 135 minutes. 105 over your allowance. £51.45 in overages. Plus £16.99 "platform fee". Plus VAT.
£19 became £87. And next month, when a cold snap hits and you get 70 calls, it'll be £130.
This isn't a hypothetical. This is how almost every "cheap" AI receptionist in the UK actually prices itself in 2026. The aiphonecalls.co.uk pricing guide showed the same pattern: base fees that barely cover anything, with per-minute overages that multiply the real cost.
What a UK trades business actually pays
Let's run the numbers for a real UK trades business. Say you're a plumber or heating engineer getting 50 calls a month during the winter season.
Each call averages 3 minutes. That's 150 call minutes a month.
The "£19" plan: 30 minutes included + 120 overage minutes at 49p = £19 + £58.80 = £77.80. Plus VAT, plus any platform or setup fees you signed up for. Real total: around £95.
The "£49" plan: 150 minutes included, so no overage on a normal month. But a busy month with 70 calls (210 minutes) means 60 overage minutes. Suddenly your £49 plan costs £49 + £29.40 = £78.40.
The flat-rate alternative: £99 a month, unlimited calls. Your bill is £99 regardless of whether you get 20 calls or 200. No overages, no surprises.
The flat-rate plan costs more on paper. It costs less in reality. Every single month that you're busy — which is every month if you're a good tradesman.
The 7 hidden fees to watch for
1. Per-call or per-minute overages
This is the big one. Nearly every "budget" AI receptionist gives you a tiny allocation of minutes or calls, then charges steep overages. IONOS starts at £39 for 30 calls with 49p overage per extra call. Dialzara caps minutes by tier. Ringmere's base tier gives 150 call minutes.
2. Setup and onboarding fees
Some providers charge £49-£99 to set up your account, train the AI on your scripts, or port your number. A flat-rate provider should include this at no cost.
3. Number porting fees
Bringing your existing business number? Some charge for it. The honest providers make porting free.
4. Script customisation charges
Want the AI to answer in your business voice, with your specific questions and pricing? Some treat that as a "premium" add-on. A proper AI receptionist should be trained to your business as standard.
5. Premium features
WhatsApp integration, CRM connectors (Jobber, Tradify, ServiceM8), emergency call routing, SMS notifications — features that should be included are often sold as add-ons at £10-£30/month extra.
6. 24/7 coverage upcharges
Some providers charge extra for overnight and weekend answering. You know, the times your competitors are closed and you could be winning their work.
7. Cancellation penalties
Lock-in contracts and notice periods. If the service doesn't work, some providers make it expensive to leave.
Flat rate vs per-call — the real comparison
Here's how the two pricing models stack up at realistic UK trades volumes:
| Volume | Per-call model | Flat-rate | Saving with flat |
|---|---|---|---|
| 30 calls/mo | £39-£55 | £99 | Flat costs more |
| 50 calls/mo | £55-£88 | £99 | Roughly equal |
| 80 calls/mo | £80-£130 | £99 | You save £20-31 |
| 120 calls/mo | £120-£190 | £99 | You save £20-91 |
| 200 calls/mo | £200-£310 | £99 | You save £100-211 |
If you get fewer than 40 calls a month, a per-call model might be cheaper. If you run a real trade business with real demand, flat-rate wins. And when winter hits, it wins by a mile.
Competitor pricing breakdown (2026)
Here's what UK AI receptionist providers actually charge in 2026 based on published pricing from HeyJodie's comparison guide, aiphonecalls.co.uk, and CXassist:
| Provider | Headline price | Real cost at 50 calls | Model | Hidden fees? |
|---|---|---|---|---|
| IONOS | £39/mo | £39-£49 | 30 calls then 49p each | Overage |
| Ringmere | £49/mo | £49-£99 | 150 minutes then overage | Limits |
| HeyJodie | £49/mo | £49-£149 | Per-call tiers | Limits |
| Answer.co.uk | £30/mo | £30-£80 | Per-call at £2.20 | Per-call |
| Dialzara | £29/mo | £65-£150 | Per-minute tiers | Overage |
| NextPhone | $199/mo | $199 | Flat unlimited | None |
| AI Suite | £99/mo | £99 | Flat rate | None |
The pattern is obvious: every provider with a headline under £49 a month gets you on overages. The only way to pay what you see is to go flat-rate.
Questions to ask before signing up
Before you buy any AI receptionist, ask these 5 questions:
- What's the exact per-minute or per-call overage rate? — If they don't publish it, assume it's expensive.
- What's included in the base price? — WhatsApp? SMS? CRM integration? 24/7 coverage? If it's not listed, it's probably an extra.
- Is setup, script training, and number porting free? — Onboarding fees are a red flag. A proper provider does this as part of the service.
- Does the price change if call volume doubles? — If the answer is yes, it's not flat-rate. Find one where the price is the same at 20 calls or 200.
- What's the cancellation policy? — 30-day rolling is fair. Anything more is a lock-in.
