IT Companies in London
Compare IT and cloud providers working in London. What the market looks like, how to narrow a very long shortlist, and when being local actually matters.
As of 23 September 2026, Compare the Cloud lists 2,141 IT providers listed under London.
How many IT and cloud providers are there in London?
Compare the Cloud lists 2,141 IT and cloud providers working in London, by a wide margin the largest concentration in the UK and several times the size of any regional cluster. The practical problem in London is therefore not finding a provider but narrowing the field, because almost every national supplier maintains a London presence whether or not the work is delivered from the city.
Does a cloud provider need to be based in London?
For cloud services delivered over the internet, a London address makes no measurable difference to performance, and buyers who filter on it usually shrink their shortlist without improving it. What genuinely depends on location is anything requiring hands on hardware: colocation and data centre access, on-site support with a guaranteed response time, desk-side IT for staff, and equipment installation or decommissioning.
What should a London business check before signing?
Ask where support staff physically sit, which is often not where the head office is registered. Ask whether the response times in the contract apply to remote support only or also to a site visit, since those are frequently different numbers. Confirm which data centre regions your data will live in, as a London-headquartered supplier may run everything from Dublin, Frankfurt or the United States.
What does IT support cost in London?
London rates sit above the rest of the UK for anything involving an engineer attending a site, because the cost reflects local salaries and travel time rather than the technical work. Cloud and managed services priced per user or per workload tend not to vary by city, so a London business paying a regional premium on a fully remote service should ask what the premium buys.

How this comparison was checked
Checked 22 September 2026 against each provider's own website, and every claim links to the page it came from. "Not published" means we could not find the fact on the provider's site; it does not mean the provider lacks it. This is a research comparison, not independent certification, customer review or endorsement. Providers are not ranked, and no paid placement is used.
These seven providers are listed in the directory's managed IT support or managed services categories with a London location, and their websites describe a managed IT service. They appear alphabetically. Confirm scope, pricing and contractual response times directly with each provider.
Questions for your shortlist
- Which engineers on your account are based in London, and how quickly can one reach your office?
- Does the quoted response time cover a site visit or only a remote response?
- Which hours does the service desk cover, and what does out-of-hours support cost?
- Which data centre regions will hold your data, whatever the head office address?
