Find a UK marketing agency you can check
Most businesses pick an agency from a sales call and a nice website. Then they find out about the minimum term, the report that shows activity instead of enquiries, and the notice period nobody mentioned. Start with agencies whose details have been checked, and the questions that protect your money.

Where hiring an agency usually goes wrong
Nobody explains how you leave
Minimum terms and notice periods often live in the terms, not on the pricing page. When we read 39 UK agency pricing pages, 19 did not say how you leave at all. Read the study.
The report shows work, not results
Rankings, posts and hours are activity. What pays the bills is enquiries and sales. If the monthly report cannot show those, you cannot tell whether the money is working. What a good report shows.
Paying for growth before the basics
An agency cannot fix a weak offer or a website that does not convert. Spend on ads or SEO before those are right and you pay to send people to a leaky page. Structure before scale.
Six things to check before you sign
Ask every agency the same questions. A good one answers in writing without fuss.
How do I leave?
Ask for the minimum term and the notice period in writing, and check the terms say the same as the sales page.
What will this cost in total?
Get one monthly figure including any setup fee. Then compare it with what UK providers publish. Check a quote.
What will the report show?
Ask to see a real report. Look for enquiries, calls and sales, not just rankings and impressions.
Who is the company?
Look the business up on Companies House. Where we have a company number, it is on the Whito listing.
Who owns the accounts?
Your website, Google Business Profile and ad accounts should be in your name, so you keep them if you move on.
What about AI search?
Plenty of agencies now sell AI search work. Ask what they will measure and how. How to check.
Why look for an agency on Whito
Checked details
Listings carry the details we could check, such as the company number. A Verified badge means we confirmed who runs the business and that its contact details work.
No paid places
Verified agencies appear first, then everyone else in A to Z order. Nobody can buy a higher spot.
No star ratings
Whito is not a review site. We do not publish star ratings or reviews, so there are none to fake.

Not sure you need an agency yet?
If you do not know what a new customer is worth to you, start there. Work out a budget from real UK prices with the marketing budget planner, or read the Whito guides and fix the basics first. An agency is worth paying when it is scaling something that already works.
