About IT Services providers
Companies providing IT consulting, support, infrastructure and technology projects for businesses.
Managed IT service providers (MSPs) run day-to-day IT for organisations: support desks, devices, networks, backups and security. A good MSP prevents problems instead of only fixing them.
In the United Kingdom, IT Services Companies are concentrated around London, Manchester, Birmingham, Edinburgh and Bristol. Local rates sit at the upper end of the global ranges, so many buyers in the United Kingdom pair a local lead with nearshore or offshore delivery to manage cost.
How to choose the best IT Services Companies in 2026-2027
- Ask which services are delivered by their own staff.
- Ask for response and resolution times written into the SLA.
- Check how they handle security, patching and backups.
- Ask for monthly reporting samples.
What does it cost?
MSP pricing is commonly $100-$250 per user per month or flat per-device fees; projects such as migrations are usually quoted separately.
Before you sign
Ask for a written proposal with scope, milestones, team members and exit terms, and speak to at least one current client of each shortlisted provider.

How this list is compiled
Worldwide view: Clutch-verified specialists (registered businesses independently verified on Clutch with a working website, ordered by their number of verified client reviews) followed by established industry leaders. Country view: the main list is strictly local. It shows only Clutch-verified firms with an office in the selected country and established firms based in that country that the iCreativez research team selected for their scale and track record. Large international firms and remote teams that serve the country appear in a separate, labelled section and are never counted as local. Where we have not yet verified enough local firms, the page says so instead of padding the list. Minimum project size, hourly rates and team size are as published by each company in November 2026. Inclusion is free and not paid for. Providers can request a review via our contact page.
