What UK mid-market buyers want from AI vendors, and what makes them walk away

UK mid-market buyers decide on credibility long before they discuss price, and once they trust a vendor they rarely switch. In the 2026 AI Enablement Services Buyer Survey (100 senior buyers, run by 10x Humans and separate from aibl’s research), 93% would reject a vendor for weak AI credibility, while just 11% call price the deciding factor. For anyone selling AI into this market, that changes where the work goes.

Credibility decides the deal before price does

Buyers screen on proof, not cost. In the 2026 AI Enablement Services Buyer Survey (10x Humans, n=100), 93% would reject a vendor for weak AI credibility and 86% name domain expertise as the deciding factor. Only 11% say price decides.

So the work that wins is demonstrating relevant expertise, not sharpening a discount. Case evidence in the buyer’s own sector, named outcomes and a credible track record open the door that a lower price does not.

Buyers stay with vendors they already know

Relationships, not outreach, drive most of this market. In the same buyer survey, 57% source vendors through existing relationships, and 89% would expand with a partner they already use rather than switch to a new one.

Being known and trusted before the buying starts beats being cheap once it has. For vendors, that makes visibility and credibility with this audience a long-term asset, not a campaign.

The buyer pool is stuck on proof, and that is the opening

The demand is real but unproven. In aibl’s survey of 755 UK mid-market leaders, only about half can show a measurable return on AI, and the gap is governance and measurement rather than the tools themselves.

That is the opportunity. Vendors who help buyers put the measurement and controls in place, so the return can be shown, close the proof gap that is holding the market back, and it is proof that drives the expansion buyers say they prefer.

What this means for how you sell AI

Lead with domain proof and named outcomes, not features or price. Get credible with this audience before the RFP exists, because most buyers are sourcing through people they already trust.

Then sell the return, not just the capability: help buyers measure what AI delivers, since that is the gap keeping half of them from proving ROI. That is what turns a first project into the expansion 89% of buyers say they would rather give an existing partner.
