Nine in ten UK businesses raised their AI budgets this year. Fewer than a third can point to a return on it. That gap between rising spend and flat results is the real AI story for UK agencies right now, and it isn’t a technology problem.
According to Spicy Advisory’s 2026 UK SMB AI adoption guide, 85-91% of UK organisations increased AI spend this year, yet only 31% report positive ROI. Seventy-seven percent saw no measurable revenue change at all. Where AI does pay off, it shows up as time saved rather than top-line growth, which would be fine, except most firms aren’t measuring time saved either, so the return is invisible even when it’s real.
ONS figures from June 2026 point at why. The average AI-adopting UK business uses just 1.6 AI tools, and only 10% report extensive use of any of them. Adoption has tripled since 2023, but depth hasn’t moved much at all. Only 15% of businesses in the 0-9 employee bracket — where most agencies sit — use AI at all, against 68% of large firms. UK firms aren’t short of AI. They’re short of depth.
There’s a skills story sitting underneath both numbers. Over 60% of firms name the skills gap as their primary barrier, and only 11% have trained more than half their workforce in AI skills. Buying a licence isn’t the same as building the muscle to use it well, and most firms are stopping at the purchase.
More tools, same problem
Tool fragmentation is Spicy Advisory’s second-named barrier to AI ROI, right behind the skills gap. It’s a pattern I run into constantly with clients: a Copilot licence bought for the whole team, a ChatGPT subscription three people actually open, a Claude account someone on the leadership team set up after a conference, and none of them wired into an actual workflow. Everyone in the building is “using AI.” Nobody’s using it for anything specific enough to measure.
Success in 2026 isn’t about using every AI tool. It’s about choosing the right tool for the right task and going deep on it, as the Stop Chasing Every New Tool newsletter put it this year.
That’s the uncomfortable part for a lot of firms: the fix isn’t procurement, it’s subtraction. Before evaluating a fourth or fifth tool, work out what the first three are actually doing for you, if anything.
Try this: a 20-minute tool audit
You don’t need a consultant for the first pass. Block 20 minutes and do this:
- List every AI tool with an active licence. Finance can usually pull this off the card statement faster than IT can list it from memory.
- Write down the one workflow each tool touches — not “content” or “admin”, but the actual task: “drafting first-pass client proposal decks”, “summarising onboarding calls”.
- Cut or pause anything without a named workflow attached. If nobody in the room can say what a tool is for, it isn’t producing ROI, measured or not, and it’s a licence you can reclaim this afternoon.
- Pick the tool touching your highest-volume repetitive task and go deep on it. Build the prompt library, the template, the checklist, whatever makes the fiftieth use faster than the first. That’s where the actual time saving lives, and it compounds; a tool used once a week never gets good enough to notice.
Most firms find step 3 uncomfortable, because “we’re paying for it, so we must be using it” feels true even when the usage logs say otherwise. Check the logs. Most seat-based AI subscriptions show login frequency somewhere in the admin panel, and it’s usually a harder number than anyone expects.
Then close the loop: whichever tool you keep going deep on, write down what you’re measuring before you start: hours saved on that one workflow, turnaround time, or output volume. Not “productivity”, a specific number tied to the specific task from step 2. That’s the difference between joining the 31% who can show ROI and staying in the 69% who are pretty sure it’s helping but can’t prove it.
The standard stack, plus one
Spicy Advisory’s guidance for UK SMBs is blunt and, in my experience, correct: standardise on Microsoft 365 + Copilot or Google Workspace + Gemini for the baseline, add one external assistant — Claude or ChatGPT — for the work your core suite doesn’t cover well, and stop there until you can show the first two are earning their keep.
That’s a smaller stack than most firms are currently running, and that’s the point. Depth over breadth isn’t a slogan here: it’s the difference between the 31% seeing ROI and the 69% who aren’t. The 31% aren’t using more tools. They’re using fewer tools for longer, on narrower, higher-volume tasks, until the tool actually knows the job.
If the audit above turns up five half-used subscriptions and nobody in the business owns the decision of what to cut or what to go deep on next, that’s exactly the kind of prioritisation call worth getting an outside, structured view on. That’s the whole point of an AI opportunity audit: not another tool recommendation, but a ranked list of where AI actually pays off in your specific workflows, and where it’s just spend.
The opinion part
AI budgets will keep rising into 2027 whether or not ROI follows: the EY and BCC data both point that way, and nobody wants to be the firm that “isn’t doing AI.” But the 69% gap between spend and return isn’t going to close by adding tool number four. It closes by someone in the business deciding which one tool gets used until it’s actually good, and which three get switched off. That decision is boring, it takes 20 minutes, and almost nobody is making it.
