The most expensive agency is not automatically the best. The cheapest is not automatically wrong. What matters is whether the supplier understands the business decision, can explain the process and leaves you in control of your digital assets.

In brief: do not compare packages alone. Compare diagnosis, accountability, measurement, account ownership and the quality of the answers to the 12 questions below. This cannot guarantee a result, but it can reduce the risk of a poor fit.

Before you request a quote

“We need marketing” usually produces a random list of services. A useful brief can be short. It should answer four questions.

ProblemWhat is blocking sales or growth today?
AudienceWho exactly do you want to reach in the UK?
ActionCall, enquiry, booking or purchase?
EvidenceWhat would progress look like in 90 days?

12 questions to ask

Do not look for a perfectly polished answer. Look for specifics, clear limits and a willingness to say “we do not know that yet”.

QUESTION 01 · OBJECTIVE

Which problem will you address in the first 90 days?

Good answerNames the problem, hypothesis and first measurable change instead of selling every service at once.

Warning sign“We will increase visibility” without naming the audience, channel or desired action.

QUESTION 02 · EVIDENCE

Which examples are genuinely relevant to my situation?

Good answerShows a relevant process, live work or anonymised evidence and explains any confidentiality limits.

Warning signLogos, followers or attractive screenshots without context, scope or the agency's role.

QUESTION 03 · PRIORITIES

What should we not do at this stage?

Good answerCan reject a channel or feature that does not fit the objective, budget or business readiness.

Warning signEvery service is “essential” and the quote grows without a delivery order.

QUESTION 04 · OWNERSHIP

Who owns the domain, website, ad accounts and data?

Good answerYour business has administrative access to key accounts, with roles and handover recorded.

Warning signEverything lives only in the supplier's private accounts, with no recovery or handover process.

QUESTION 05 · PRICE

What is included and what will cost extra?

Good answerSeparates setup, ongoing fees, media spend, licences, revisions and exclusions.

Warning signA single “from” price with no version limits, timeline, maintenance or change terms.

QUESTION 06 · EXIT

How does the relationship end and what do I receive?

Good answerExplains notice, data export, file transfer, access and documentation.

Warning signUnclear penalties, no handover plan or a site that depends permanently on one supplier.

QUESTION 07 · OUTCOME

Which business result matters and which metrics support it?

Good answerSeparates enquiries, bookings or sales from clicks, reach and rankings.

Warning signSuccess will be judged only by reach or follower count.

QUESTION 08 · MEASUREMENT

What must be configured before the campaign starts?

Good answerDefines a baseline, conversion events, user consent and data quality checks.

Warning signBudget is due to launch immediately even though no one can attribute enquiries.

QUESTION 09 · REPORTING

How will the report change the next decision?

Good answerConnects result, reason, learning and next action instead of showing a chart alone.

Warning signAn automated PDF with no explanation, priorities or optimisation plan.

QUESTION 10 · AI

What do you use AI for and who approves the result?

Good answerSeparates research, drafting, analysis and automation, with human review and fact-checking.

Warning sign“Everything is done by AI” with no accountability for errors, brand voice or rights.

QUESTION 11 · DATA

How do you protect company data, access and assets?

Good answerExplains permissions, storage, external tools, backups and incident handling.

Warning signSensitive information is copied into random tools or shared without access controls.

QUESTION 12 · DELIVERY

Who decides, who responds and how are changes approved?

Good answerHas an owner, communication rhythm, approval windows and a change process.

Warning signAfter the sale, no one knows who leads the project or where decisions are recorded.

A simple 0–24 scorecard

Score each answer after the call. It does not replace judgement, but it makes it harder to decide on price or presentation alone.

ScoreWhat it meansNext step
0 pointsNo answer or an evasive answer.Clarify the risk before signing.
1 pointThe direction makes sense, but scope, ownership or evidence is missing.Ask for the detail in the proposal or agreement.
2 pointsThe answer is specific, relevant and verifiable.Compare delivery quality, cost and team fit.
19–24 pointsA solid basis for a commercial conversation. Still check references and documents.
13–18 pointsThere is potential, but material gaps should be clarified in writing.
0–12 pointsToo much risk or too little detail for a confident decision.
03

Warning signs that matter

A small agency may not have hundreds of reviews, and a large supplier is not automatically the right fit. Focus on control, honesty and verifiability.

Be cautious when…

a supplier guarantees a Google position, withholds account access, leaves scope undefined, mixes media spend with fees, publishes unchecked AI content or avoids explaining what happens to your data at the end.

Check evidence, not popularity

Followers, badges and polished profiles may create a first impression. Base the decision on a relevant process, real work, clear access and a credible measurement plan.

04

Does a Polish-speaking team help?

It can improve communication, but it is not automatically a strategic advantage. Check whether the team understands the UK market, local search intent, bilingual messaging, advertising standards and data protection.

Agency or freelancer?

A freelancer can be ideal for one well-defined task. A team helps when strategy, design, development, SEO, advertising and analytics must work together. The label matters less than accountability and the skills required for the scope.

FAQ

Questions about choosing a UK marketing agency

How can you recognise a good marketing agency in the UK?

A good agency connects activity to a business objective, defines scope and costs, agrees account and data ownership, explains measurement, and discusses limitations and risk as well as opportunity.

How many questions should you ask before signing?

Our list covers 12 areas: strategy, evidence, priorities, ownership, costs, exit, outcome, measurement, reporting, AI, data security and communication.

Is a long agency contract always a warning sign?

Not necessarily. Clear notice periods, minimum terms, responsibilities, account handover and what happens to data and assets after the relationship ends matter more than length alone.

Does an agency's follower count prove its effectiveness?

No. It may reflect the reach of the agency's own profile, but it does not replace a relevant process, suitable evidence, transparent measurement or client account ownership.

How can you check whether an agency uses AI responsibly?

Ask what AI is used for, who approves outputs, what data is shared with external tools, how facts are checked and who owns the rights to final content and assets.
