Top Web Design Companies in the UK

1,386 IT service providers ranked by rating, review volume and listing quality.

Web design is the part of a website a visitor experiences directly: layout, typography, imagery, and how a page behaves on a phone as well as a desktop. It overlaps with web development and is often sold alongside it, but the skills are distinct — design decides what the thing should be, development makes it work.

Providers differ most in what they hand over. Some deliver a design system — components, states and rules a developer can build against — while others deliver flat mockups of a handful of pages. Ask what happens to the screens nobody drew: an error state, an empty list, a very long company name. Ask whether accessibility is part of the work or an afterthought, because retrofitting it is considerably more expensive than designing for it.

Between them, the 600 best-ranked of these 1,386 IT service providers cover web development (571), UI/UX design (371), eCommerce (279) and WordPress (252). They also list work in London. 592 of them have written a profile you can read before you get in touch.
