Top IT Service Providers for WordPress in the UK

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

WordPress runs a very large proportion of the world's websites, which means the providers listing it range from firms that install a purchased theme to teams that build bespoke systems on it as an application framework. The gap between those two is enormous and the label does not distinguish them.

The questions that do: is this a custom theme or a licensed one, and who renews the licence? How many plugins does the build depend on, and what happens when one is abandoned? Who applies core and plugin updates after launch, and how quickly when a security release lands? Most inherited WordPress problems trace back to a site nobody was contracted to maintain.

Want your company here?

Between them, the 600 best-ranked of these 750 IT service providers cover web development (586), web design (569), eCommerce (512) and IT services (500). They also list work in London. 597 of them have written a profile you can read before you get in touch.

We list more than 750 IT service providers in the UK listed for WordPress. The order comes from what each firm publishes and what has been verified about it, never from payment — at the top right now: Webcurl LTD, Website Express and Strange.

Before you shortlist, check

Sites they built that are still maintained
Which plugins they rely on, and who pays for and updates them
Hosting, backups and security updates, written into the contract
That you get full admin access and own the theme

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 (749) · India (274) · Ireland (107) · Italy (82).

Other specialisms in the UK: UI/UX design (941) · e-commerce (854) · Android app development (812) · iOS app development (800) · PHP development (728).
