Trust in Advertising Is Up: What UK SMEs Should Do

Most small businesses assume the public is cynical about ads. The data says it’s more complicated — and more encouraging.

Credos’ latest Trust Tracker found 40% of the UK public trusted advertising in 2025, the highest level since 2021. That’s not a “everyone loves ads now” moment (only 11% say they’re very trusting), but it is a meaningful shift in the right direction. And for UK small businesses trying to stretch limited budgets, that shift matters: when trust rises, ads work harder.

This post sits within our “Governance, Regulation & Public Trust” series for a reason. Advertising doesn’t exist in a vacuum. The same forces shaping public trust in institutions — transparency, accountability, fraud prevention, clear standards — are shaping trust in marketing. If you’re a small business, you don’t need to outspend big brands. You need to out-clarify them.

What the trust numbers actually mean (and what they don’t)

Credos’ 2025 results are a useful reality check:

• 40% trust advertising (11% very trusting, 29% fairly trusting)
• 25% actively distrust advertising
• 33% neither trust nor distrust (the persuadable middle)

The headline is “highest in five years”, but don’t ignore the detail: 40% is only one point up on 2024 (39%). The bigger story is the longer arc — trust was 31% in 2021, dropped further in 2022, and has clawed back.

Here’s my take: this isn’t a sudden love for advertising. It’s a sign that people are getting better at filtering. They’re more alert to scams and manipulation, but they’ll still reward brands that are clear, consistent, and honest.

From a lead-generation standpoint, that “neither trust nor distrust” 33% is gold. They’re not anti-advertising. They’re anti-dodgy advertising.

Why trust is rising: the push-pull behind consumer confidence

Credos describes the picture as “complex” and at times “contradictory”. That tracks with what most of us see day-to-day.

The research found the drivers of trust are split 50/50 between positives and negatives. In plain English: trust isn’t built only by doing good things — it’s also destroyed by avoiding bad ones.

The biggest trust-killer: “suspicious advertising”

Credos points to “suspicious advertising” as a major driver of distrust, including:

• scams
• misleading ads
• undisclosed ads
• greenwashing
• manipulated images

For UK SMEs, this connects directly to the wider governance theme: when regulation and enforcement struggle to keep pace (especially online), the burden shifts to brands to self-police if they want long-term trust.

Practical SME stance: if your sector has known bad actors (trades, health and beauty, finance, property, training), you should market like your prospects have been burned before — because many have.

The biggest trust-builder: enjoyment (yes, really)

On the flip side, enjoyment was the factor most likely to drive trust in advertising.

That sounds fluffy until you translate it: enjoyment is often a proxy for “this feels human” and “this doesn’t feel like a trick.” Simple, well-made ads that respect attention tend to be trusted more than hyper-optimised, over-targeted, desperation messaging.

For a small business, “enjoyment” doesn’t mean hiring a film crew. It can mean:

• a clean message and one offer
• a friendly tone that sounds like you
• real photos of your team/work
• proof that the product exists and works

Trust by channel: what UK consumers believe most

Credos found trust increased across every advertising channel compared to 2021. But the ranking is what small businesses should pay attention to.

Traditional channels are still the trust leaders

• TV: 46% trust in 2025 (up from 33% in 2021)
• Cinema: 42% trust in 2025 (up from 33% in 2021)

The point isn’t “go buy a TV spot”. For most SMEs, that’s unrealistic.

The point is: channels associated with stronger rules, clearer labelling, and fewer scams are trusted more. That’s a governance lesson. Environments with better standards get better trust.

So when you choose digital channels, choose placements and formats that feel more like “high-standard environments” — and build your ads to match.

Social and influencer ads are improving — but still lag

• Influencer advertising: 25% trust in 2025 (up from 19% in 2021)
• Social media advertising: 27% trust in 2025 (up from 20% in 2021)

This is the trade-off: social gives you targeting and speed, but it carries trust debt because it’s where people encounter scams, undisclosed promos, and manipulated claims.

If you rely heavily on Meta, TikTok, or influencer partnerships, your job isn’t just to generate clicks. It’s to de-risk the decision for the buyer.

A trust-first playbook for small business lead generation

If you want more leads from digital marketing in 2026, treat trust like a conversion asset. Here’s a practical approach I’ve seen work across service businesses, ecommerce, and local trades.

1) Build ads that can survive scrutiny

Write ads as if the prospect will:

• open a new tab and Google you
• check your reviews
• look for inconsistencies in your pricing
• ask “what’s the catch?”

Trust-first ad checklist:

• Name the offer clearly (avoid vague “limited time” language unless it’s real)
• Use accurate before/after claims (or none at all)
• Include constraints (“from £X”, “appointments available in Y area”, “typical turnaround Z days”)
• Match the landing page exactly (same price, same promise, same wording)

A snippet-worthy rule: If your landing page has to explain what your ad “meant”, your ad was the problem.

2) Make disclosure and transparency obvious (not hidden)

Online trust collapses when people feel tricked. If you’re using:

• paid partnerships
• affiliate links
• AI-generated imagery
• “from” pricing

…say so plainly.

This isn’t just about compliance. It’s about signalling that you’re not trying to sneak anything past them. That’s the heart of public trust.

3) Use proof that’s hard to fake

Prospects trust what scammers struggle to copy.

Good proof for SMEs:

• recent customer reviews (with dates)
• photos of real jobs (not stock images)
• short videos showing the product/service in use
• named team members and a real address (where relevant)
• clear returns, guarantees, and complaints process

A strong stance: A “trust badge” means little if your policies are vague. Your policy page is part of your marketing.

4) Pick channels that fit your trust level (and budget)

You can’t buy trust instantly, but you can borrow it from the right environments.

A sensible SME mix (often effective for lead gen):

• Google Search ads for high-intent queries (trust tends to be higher when the user is actively searching)
• Local SEO + Google Business Profile to reinforce legitimacy
• Meta retargeting but with conservative claims and strong proof
• Email to turn “neutral” visitors into warm leads over time

If your category is high-risk (financial promises, health outcomes, “too good to be true” savings), avoid leading with aggressive social prospecting. Start with search and proof-led content.

5) Don’t confuse “attention” with “trust”

Credos found enjoyment drives trust, but that doesn’t mean loud ads win.

If your ads are getting cheap clicks but poor leads, you may be optimising for the wrong thing. Try tracking:

• lead-to-quote rate
• quote-to-sale rate
• refund/complaint rate by acquisition channel

A governance-style metric that helps: track “cost per qualified lead,” not just cost per lead. Low-trust channels often produce high volumes of low-quality enquiries.

People also ask: practical trust questions SMEs have

“Is now a good time to invest in advertising as a small business?”

Yes — if you build around transparency. With 40% of the UK public saying they trust ads (2025), the environment is better than it’s been in years. But the penalty for shady or sloppy messaging is high.

“Which ad channels are most trusted in the UK?”

Credos reports TV is most trusted (46%), followed by cinema (42%). Social and influencer ads are improving but remain lower (27% and 25% respectively).

“How can I make my online ads feel more trustworthy?”

Use specific claims, clear pricing, real proof (reviews, photos, video), obvious disclosures, and landing pages that match the ad precisely. Remove anything that could feel like a trick.

Trust is the competitive advantage most SMEs ignore

The Credos results — trust up to 40%, trust rising across channels, and strong distrust driven by scams and misleading tactics — point to a simple reality: buyers aren’t rejecting advertising; they’re rejecting uncertainty.

That ties neatly back to the “Governance, Regulation & Public Trust” theme. When people feel the system is messy, they reward the businesses that bring clarity. Your marketing can either add to the noise or act like a signal.

If you want more leads in 2026, take a trust-first stance: say what you do, what it costs, who it’s for, and what happens if it goes wrong. Then run ads that repeat it consistently.

Where could your business be by summer 2026 if every paid click landed on a page that instantly answered, “Can I trust these people?”
