Top IT Service Providers for UI/UX Design in the UK

939 IT service providers ranked by rating, review volume and listing quality.

UI and UX design are usually sold together and are not the same thing. UX is the shape of the product — what it does, in what order, and what a user is trying to achieve. UI is the surface: the controls, the visual language, the details of interaction. A product can be beautifully rendered and still ask people to do something illogical.

The most informative question for a provider here is what research they do before drawing anything, and what they do when it contradicts the brief. Teams that go straight to high-fidelity screens produce work that looks decisive and tests badly. Ask to see a project where the research changed the plan.

Between them, the 600 best-ranked of these 939 IT service providers cover web development (572), web design (548), eCommerce (397) and WordPress (323). They also list work in London. 594 of them have written a profile you can read before you get in touch.

We list more than 900 IT service providers in the UK listed for UI/UX design. The order comes from what each firm publishes and what has been verified about it, never from payment — at the top right now: Eton Digital Limited, Website Express and ADVOX Studio.

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 (1,355) · India (643) · Germany (422) · Poland (259).

Other specialisms in the UK: e-commerce (854) · Android app development (812) · iOS app development (800) · WordPress (752) · PHP development (728).
