Managed IT support for London businesses
London businesses move fast. Their IT needs to keep up — and their IT provider needs to be able to respond when things go wrong, wherever their people are working. Kaizen IT has been supporting businesses in London with managed IT services, cyber security, and strategic IT consultancy for over two decades.
From fast-growing scale-ups in Shoreditch and creative agencies in Soho, to professional services firms in the City and West End — we understand the demands of London’s business environment and the technology that drives it.
Why London businesses choose Kaizen IT
We’re independently owned, ISO 27001 and ISO 9001 certified, an Apple Premium Technical Partner and Microsoft Partner. That combination of credentials, experience, and genuine cross-platform expertise is rare — and it’s what sets us apart from the generalist IT companies that serve the London market.
We support businesses running macOS, Windows, or a mixed estate — managing both seamlessly. Our London-based field engineers provide on-site support when remote troubleshooting isn’t enough, and our helpdesk is staffed 7am–7pm to cover the full working day and beyond.
What our clients say...
“They provided the expertise and guidance we needed, allowing us to focus on building our business — confident in the security and reliability of our technology.”
“Their team are responsive, knowledgeable and pragmatic, always focused on practical solutions that work for the business.”
Our London IT support services
Managed helpdesk support
Our helpdesk is staffed 7am–7pm, Monday to Friday as standard — covering remote troubleshooting, software support, device queries, and account management. 24/7 emergency cover and US hours extension are available as add-ons for businesses that operate outside standard hours.
On-site support across London
Our field engineers provide on-site support for London businesses — covering hardware installations, network infrastructure work, and on-site project delivery. On-site response within four to eight working hours depending on your service level agreement.
IT security assessment
We assess your IT environment across 36 individual controls in 9 categories — covering identity and access management, endpoint and device security, network infrastructure, data and cloud configuration, email and communications, resilience and recovery, people and process, monitoring and response, and security certification and compliance. Included free for all new clients, with a plain-language report and prioritised action plan.
Strategic IT consultancy
We build a technology roadmap around your business — covering cloud and server strategy, workstation lifecycle planning, device management, backup and disaster recovery, and compliance accreditation support for ISO 27001, Cyber Essentials, and SOC 2.
Cyber security
From managed detection and response through our partnership with Huntress, to DMARC email authentication, Mailsafe email filtering, and Huntress Managed SAT — we protect London businesses against the threats that matter most.
Frequently asked questions
Do you have engineers based in London?
Yes. Our headquarters and engineering team are based in Sheffield. When you need someone on-site, we’re already here.
What areas around London do you cover?
We support businesses across Greater London. On-site response times are four to eight working hours depending on your service level agreement.
How quickly will you respond to a support request?
When you log a call, one of our technical team will begin troubleshooting within 30 minutes on a best endeavours basis. We actively monitor all open tickets and escalate if a ticket hasn’t received a response within two hours of being logged.
Do you support Apple devices as well as Windows?
Yes — as an Apple Premium Technical Partner we support macOS, Windows, iOS, and Android within the same business environment. We manage mixed Mac and Windows estates seamlessly and have certified Apple specialists in our team.
Can you help us switch from our current IT provider?
Yes. We manage the transition end to end — coordinating with your outgoing provider, auditing your existing infrastructure, and scheduling the cutover to minimise disruption. A typical switch takes two to three weeks.
What contract options do you offer?
New clients start on a 90-day initial term, then monthly rolling with 30 days’ notice to cancel. Once you’re comfortable with our service, you can move to a two- or three-year agreement with associated cost savings.
