Choosing a digital supplier in the public and cultural sector

Written by David • September 12, 2026

I’ve written a fair few tender responses, and read a lot of tender documents. The pattern is consistent: the way a brief is written largely determines the quality of supplier who responds to it.

If you’re commissioning design or digital work in a council, trust, university or funded organisation, here’s what’s worth thinking about.

What actually predicts a good outcome

Relevant experience, not just a big client list. A supplier who has worked with organisations of your size, structure and constraints will understand things a larger client list doesn’t demonstrate. Working with a committee, a seasonal team or a fixed funding window is a skill in itself.

Evidence of outcomes. Ask what changed as a result of the work, not just what was delivered. Good suppliers can tell you. Ask for referees you can actually speak to, and speak to them.

Honesty about scope. A supplier who tells you part of your brief is unrealistic within your budget is more useful than one who agrees to everything. The second one will be raising it as a variation in month three.

A clear plan for handover. Who maintains it, how the team is trained, what happens when the contract ends. This is where publicly funded projects most often come unstuck.

Accessibility as standard. Public sector bodies have legal obligations here. Any supplier should be able to explain how they meet WCAG 2.2 AA without being prompted, and how they’ll test it.

What to put in the brief

A realistic budget or range. Withholding it produces proposals that are all pitched at different scales and can’t be compared fairly. It also makes scoring on price close to meaningless.

The real decision-making structure. If a board signs off, say so, and say when it meets. Suppliers can plan around it if they know.

What you already have. Content, brand assets, existing systems, hosting arrangements. Whether the content is being rewritten is one of the biggest variables in a web project cost, and it’s frequently left unstated.

What happens after go-live. Support, hosting, ongoing development. Say whether it’s in scope, so it’s priced properly rather than becoming a surprise later.

Sensible evaluation criteria. If quality matters more than price, weight it that way. And be clear about what you’re actually scoring, so responses address it.

Things that put good suppliers off

• Very short response windows, particularly over holiday periods.
• Requests for speculative design work as part of the bid.
• Turnover thresholds or insurance requirements set far above the value of the contract.
• Question sets that are clearly recycled from a construction framework.
• No named contact for clarification questions, or answers that arrive two days before the deadline.

Each of these narrows your field to whoever has the capacity to absorb the overhead, which isn’t the same as whoever would do the best work.

Small suppliers and sole practitioners

Procurement processes often favour scale, but size doesn’t always predict quality. A small studio or an independent consultant typically gives you direct access to the senior person doing the work, rather than a senior person at the pitch and a junior team afterwards.

The fair way to test it is on capacity and continuity: what happens if they’re ill, what the backup arrangements are, who else they can draw on. Those are reasonable questions, and a good small supplier will have clear answers.

After the award

Two things make a noticeable difference:

Give a debrief. Unsuccessful bidders put real work into responses. Feedback costs you little and improves the quality of the field next time.

Keep the same people in the room. Projects go wrong when the people who wrote the brief hand over to people who weren’t part of the conversation. Continuity on your side matters as much as on the supplier’s.
