The order is earned on evidence: client reviews, vetting, awards and the facts a business states on its own website, which we read and date. Nobody can pay to move up. Add reviews or verified facts to your free profile to move up at the next edition; there are two ways to stand out now, and each one says what it is.

How is this ranking worked out?

The order comes from what each firm publishes and what has been verified about it, and never from payment:

Profile completeness: the details a buyer needs to judge a firm — what it does, who it serves, how it prices, who it has worked for
Earned trust: verification, awards and the other checks a firm has actually passed
Client reviews, where they exist: the rating is smoothed, so one five-star review cannot outrank a firm with a hundred good ones, and volume counts with diminishing returns

Client reviews are still rare across this catalogue, so on most lists today the order is set by the first two. A firm near the top is the best-documented and best-verified one we hold, which is not the same claim as the best one to hire. Use the list to build a shortlist, then check the firms yourself.

Sponsored listings are labelled and shown apart from this list. How rankings work

Only firms whose profile names the UK are counted here, so a firm that lists a town but no country is not yet included.

Where else can I look?

The same list elsewhere: USA (416) · India (209) · Germany (110) · Canada (100).

Other specialisms in the UK: UI/UX design (941) · e-commerce (854) · Android app development (812) · iOS app development (800) · WordPress (752).
