How much does it cost to bring AI into a small UK business?

Bringing AI into a small UK business can cost nothing extra in software, because the tools you already pay for increasingly include it. The real costs sit in four layers: AI inside your existing software, standalone AI tools, your own time, and outside help. This guide prices each one, using Simplish AI's own published prices as the example for outside help.

What are the cost layers of bringing in AI?

There are four cost layers, and most small teams should work through them in this order.

What does AI cost in software you already pay for?

For many small businesses, the first layer of AI costs nothing extra because it is already inside software they pay for. The job is to find it and switch it on.

Microsoft offers Copilot Chat to Microsoft 365 business users, with the fuller Microsoft 365 Copilot, which works inside Word, Excel, Outlook and Teams with your own files, sold as a paid add-on. Google now includes Gemini features in its Workspace business plans.

Accounting software is worth a look too. If you are VAT registered, HMRC's Making Tax Digital rules already require you to keep digital records and file VAT returns through compatible software, so you are likely paying for a package that has added automation features of its own.

What do standalone AI tools cost?

Standalone AI tools are usually priced per person, per month, with a free tier and one or two paid tiers. The paid individual plans of ChatGPT, Claude and Gemini sit at similar price points, and their team or business plans add admin controls and different data terms.

Automation tools that connect your apps together, such as Zapier and Make, both offer free plans, with paid tiers priced on how much they run.

Two cautions. If client or staff details will pass through a tool, UK GDPR still applies, so a business tier with suitable data terms may be the right choice. And subscriptions creep: one tool per job, checked monthly, keeps this layer small.

What does your own time cost?

Your own time is often the largest cost of bringing in AI, and the one nobody budgets for. Learning a tool, testing it on a real task, setting it up properly and showing the team how to use it all take hours.

I learned this while building Danni, our AI business analyst. My first working automation took me an age of trial and error; by the fifth one, it was second nature. Those hours are the investment. We value those hours at £15 an hour, the cost of delegating the work, never your own charge out rate. On that basis, twenty hours spent learning and setting up one workflow costs £300. Modest, but those hours usually come out of evenings and weekends.

What does outside help cost?

Outside help ranges from free to a monthly retainer, and the right level depends on how many hours are at stake. Here is how Simplish AI prices each level.

Free help. The Hidden Hours Score takes 16 questions and three minutes and shows where your team's hours are going. The free Mini Assessment is a ten minute call with Danni, our AI business analyst, about one repetitive task, then a fifteen minute call where I hand you the fix. I also host AI for Business Bournemouth, a free monthly meetup for non technical owners.

A one off assessment. The £997 assessment is a 45 minute discovery call with Danni, a nine slide report within 48 hours costing five to seven opportunities in hours and pounds, and a 60 minute Results Session with me. Every recommendation names the tool, its monthly cost and its setup time. The report will identify at least 5 hours a week you and / or your team could get back, or you receive a full refund.

Monthly implementation. The AI Concierge is £1,500 a month: two 45 minute working sessions a month, building between calls, priority support by email or WhatsApp, and a ledger of the hours each change returns. It is rolling monthly, and you can cancel with 30 days notice.

Custom builds. I've moved away from custom builds unless the workflow is so high volume that it absolutely justifies the bespoke cost. If a custom build is needed, it's quoted per project, and only recommended when the hours involved earn it.

I learned that the hard way. Early on, I engaged a company to custom build a CRM for my own business. It took three years, ended up costing ten times the original quote, and in the end, it was so unusable we junked the whole thing. It was a brutal lesson: complexity is not a strategy. We only started really winning when we stopped looking for the "perfect" custom build and started looking for the simplest way to fix the tasks that actually took time.

How do you know whether the cost is worth it?

Compare the cost against the hours it frees, valued honestly. One hour a week across 48 working weeks is 48 hours a year, worth £720 at £15 an hour. Five hours a week is 240 hours a year, worth £3,600.

On that basis, a £997 assessment covers its cost if it leads you to recover about 67 hours over a year, a little under an hour and a half a week. A monthly retainer should be judged the same way: by its ledger of hours returned, reviewed regularly, and by what that reclaimed time goes into. If the ledger does not justify the fee, stop paying it.

Who is this guide for, and who is it not for?

This guide is for owners of businesses with three to twelve people who want a realistic budget before committing to anything. It assumes admin is spread across a team, not sitting with one person.

It is not for larger organisations planning enterprise AI programmes, or for anyone looking for a price comparison between consultancies.
