Top Mobile App Development Companies in the UK

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

Mobile app development covers applications built for phones and tablets, whether native to one platform, cross-platform from a shared codebase, or a web application wrapped for the stores. All three are sold under this heading and they have materially different costs, both to build and to keep running.

The recurring surprise for buyers is that shipping is not the end of the spend. Both stores change their requirements on their own schedule, and an app that is not updated will eventually stop being accepted or stop working. Ask what the maintenance arrangement is before comparing build quotes, because a lower build price with no maintenance path is not the cheaper option.

How many mobile app development companies are there in the UK?

412 companies on TrustList offer mobile app development and are based in the UK. That makes the UK the number 3 mobile app development market we rank, after the USA, India.

How is this ranking worked out?

Each firm's position comes from its client reviews and its profile, blended into one score:

Rating, smoothed so a single five-star review cannot outrank a firm with hundreds of good ones
Review volume, with diminishing returns
Profile completeness: the details a buyer needs to judge the firm
Earned trust: verification and awards, as a small lift

No firm can pay for a position. Sponsored listings are labelled and shown apart from this list. How rankings work
