Top IT Service Providers for .NET in the UK

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.
