AI chatbot cost for a UK small business (2026)
Most AI chatbot cost guides quote you in dollars. Here's what an AI chatbot actually costs a UK small business in pounds, and what you get at that price.
Search for how much an AI chatbot costs and most of what you'll find is priced in dollars. $50 a month here, $5,000 for a custom build there. None of it is wrong exactly, but it's not UK pricing, and a currency conversion doesn't tell you what a UK small business actually pays for a chatbot built and looked after properly.
Here's the real UK number.
What it actually costs
For a done-for-you chatbot, trained specifically on your business and connected to how you already handle enquiries, expect to pay from £750 one-off for setup, then £50-100 a month after that. leeday.uk's own chatbot, Ada, sits at exactly that price. The setup fee covers the build and training. The monthly fee covers hosting, monitoring, and keeping it up to date as your business changes.
That's not the cheapest option out there. No-code tools like the ones most of those dollar-priced guides are describing can run £20-100 a month with no setup fee at all. The trade-off is you're doing the setup and training yourself, and you're working within whatever that platform lets you customise.
What you get for the setup fee
A proper build isn't just a chat widget bolted onto your website. It should come with real guardrails: a daily spend cap so costs can't run away, rate limiting so it can't be spammed, a message cap per conversation with a clean hand-off to email once it's reached, and a kill switch if something needs shutting off fast. It should also be resistant to prompt injection, the trick where someone tries to talk the bot into saying or doing something it shouldn't.
That's the difference between a chatbot that's genuinely safe to leave running unattended and one that technically works until it doesn't.
When a no-code tool is actually enough
If all you need is basic FAQ answering (opening hours, where you're based, what you do) and you don't mind the setup yourself, a no-code tool is a fine starting point. Where it usually falls short is anything that needs real training on your specific business, or a proper hand-off when the bot hits the edge of what it knows.
Working it out for your business
The honest answer to "how much should I spend on a chatbot" depends on what it's actually replacing. If it's saving you from answering the same five questions over and over, or catching enquiries outside your hours, the setup fee usually pays for itself fast. If you're not sure which category you're in, what an AI automation can actually do for a small business is a good place to work that out before spending anything.

Frequently asked questions
How much does an AI chatbot cost for a UK small business?
For a done-for-you build trained on your business, expect from £750 one-off setup, plus £50-100 a month for hosting, monitoring, and keeping it current. No-code DIY tools can be cheaper month to month, but you're doing the setup and training yourself.
Why do most chatbot pricing guides quote dollars, not pounds?
Most of the widely-shared chatbot cost content is written by US-based SaaS platforms or content marketers targeting a US audience. The figures aren't wrong, they're just not UK pricing, and currency conversion alone doesn't account for how UK providers actually price done-for-you setups.
Is a no-code chatbot tool enough, or do I need a custom build?
If you just need basic FAQ answering and don't mind setting it up yourself, a no-code tool can work. If you want it trained specifically on your business, connected to your enquiry flow, and with guardrails around what it can and can't say, a done-for-you build is the safer option.
What's included in leeday.uk's AI chatbot setup?
Full training on your business, a daily spend cap, rate limiting, a per-conversation message cap with hand-off to email, an instant kill switch, and prompt-injection resistance built in. It works via the Anthropic Claude API and doesn't train on your conversation data.
