UK SMEs using AI are saving 5 hours a week. Here's what they're actually doing.

New OpenAI research found that UK small businesses using AI are saving an average of 5.2 hours per week. More than half a working day, every week, without taking anyone on.

The figure comes from a survey of 1,000 UK SME decision-makers, published in March 2026. What's interesting isn't just the number. It's who's seeing those results. It's not the most technically sophisticated businesses. It's the ones who picked one specific problem, got it working, and moved on to the next thing.

What they're actually using AI for

Research and summarisation is the most common use, cited by 47% of UK SMEs currently using AI. Pulling together competitor research, summarising long documents, turning a pile of notes into a clear action list. Work that used to take an hour now takes ten minutes.

Email and customer communications comes in at 42%. Drafting responses, writing follow-ups, handling the enquiries that ask the same questions every week. Not replacing the judgement in what to say, but getting rid of the blank-page problem.

Brainstorming is cited by 39%, using AI as a sounding board rather than a doer. Stress-testing ideas, generating options, thinking through decisions out loud.

And then there's the everyday admin that doesn't make headlines: formatting documents, scheduling, chasing invoices, logging things between systems. The necessary stuff that doesn't move the business forward but still gets a human's time.

What they're doing with the time back

The research found that UK SMEs reinvesting their saved time are putting it into creative thinking and problem solving (32%), strategic planning (30%), and improving products and services (30%).

That's the work that tends to get squeezed out by admin. Buying it back is the point.

Most UK businesses still aren't there

One in five UK SMEs (19%) still don't use AI at work at all. Among sole traders it's 37%. Among business owners aged 55 and over, 40% haven't started.

The most common barrier isn't cost. It's skills and confidence. 28% of non-users said training was the main reason they hadn't started, which is worth sitting with given that most of the tools driving these results cost between £0 and £20 a month.

ChatGPT is the most widely used, by 64% of AI-adopting SMEs, ahead of Gemini and Microsoft Copilot at 42% each.

Why some businesses save 2 hours and others save 10

The 5.2 hours figure is an average. The spread is much wider in practice.

The difference usually comes down to two things: which tasks you've picked, and whether you've given the tool enough context to be useful.

A business owner who pastes a customer enquiry into ChatGPT and asks for a reply will save a few minutes. A business owner who has spent an hour writing a prompt that knows their tone, their common questions, and what they'd never say will get something they can send with almost no editing. Same tool. Very different result.

The businesses doing well tend to have one workflow properly set up, and they leave it running while they move on to the next one.

Where to start

Pick a task, not a tool.

Find something you do every week that follows a predictable pattern, something you could describe step by step to a new employee. Write out what you'd want a capable assistant to do. Then test it with whatever AI tool you already have access to.

It won't be right first time. That's fine. Most people see a noticeable difference within the first week or two of actually using it, not just trying it once.

Try this on Monday: take the last three customer enquiries you've responded to, paste them into ChatGPT or Claude with a short description of your business, and ask it to draft replies. See how close they are to what you'd have written yourself. That gap tells you how much editing you'd need to do, and whether it's worth it.
