Top IT Services Companies in the UK

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

IT services is the broadest label in this directory and covers, at different firms, entirely different work: managed infrastructure and helpdesk, project-based software delivery, cloud migration, security, procurement, or some combination sold as one relationship. Two providers under this heading may have almost nothing in common.

Because the label is wide, the useful filter is the engagement model rather than the capability list. Is this a retained relationship with a service-level agreement and a monthly cost, or project work quoted per piece? Who is accountable when something breaks at two in the morning, and what does the contract actually promise? A provider that answers those precisely is describing a real service; one that answers in capabilities is describing a brochure.

Want your company here?

Between them, the 600 best-ranked of these 872 IT service providers cover web development (569), web design (556), WordPress (459) and eCommerce (440). 597 of them have written a profile you can read before you get in touch.

TrustList ranks more than 850 IT services companies in the UK, ordered on client reviews and profile quality, never on payment. At the top right now: NetMonkeys Ltd, Pen Test Partners and Innovation Group Limited.

What to check before you shortlist a IT services company

  • Service levels and response times, in the contract
  • Security certifications that match your obligations
  • What is covered on site and what is remote
  • Exit terms: how you get your data and credentials back if you leave
Filter by fitbudget, engagement, size and more

Only businesses that have told TrustList match a filter. Filters never change the order or a score.

How many IT services companies are there in the UK?

872 companies on TrustList offer IT services and are based in the UK. That makes the UK the largest IT services market we rank.

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

What else do firms in the UK offer?

We also rank web development (1,531), web design (1,385) and software development (443) in the UK.
