Outsourced IT Support
A complete IT team without a single hire.
Outsourced IT support gives your business access to a full technology team — helpdesk, cybersecurity, cloud administration, device management, and monitoring — without the overhead of hiring in-house. For small businesses with 1 to 50 staff, it's the most cost-effective way to get enterprise-grade IT.
Senri provides outsourced IT services to small businesses across London and the UK. We're not a faceless helpdesk. You get a dedicated team that knows your business, your systems, and your people. When you call, a real person picks up the phone — every time.
We use the same enterprise tools — Microsoft Defender, Intune, Purview, Conditional Access — that protect organisations ten times your size, configured specifically for smaller teams at a fraction of the cost.
Why Outsource Your IT Support?
Most businesses don't outsource because they want to — they outsource because one of these happened.
Your IT person left
The one person who knew how everything worked handed in their notice. Nobody has the passwords, the documentation is a shared Google Doc that hasn't been updated in two years, and your team is stuck. Outsourcing to an MSP gives you a whole team overnight — no recruitment, no ramp-up.
You can't justify a full-time hire
A full-time IT person costs £35,000–£45,000 minimum before NI, pension, training, and equipment. For a team of 5–30, that's hard to justify when you only need 10–15 hours of IT work a week. Outsourced IT support gives you everything a full-time hire would — plus specialist cybersecurity and cloud expertise they probably wouldn't have.
Your current provider isn't cutting it
Tickets go unanswered. Issues reappear. You're paying monthly but nothing feels proactive. Switching to a responsive, transparent outsourced IT partner doesn't have to be painful — we handle the transition end to end and most businesses are fully migrated within a week.
You're growing and IT can't keep up
New starters wait days for a configured laptop. Shadow IT is creeping in. Security is an afterthought. Outsourced IT support scales with you — onboard five people this month, two next month, without touching headcount.
What's Included
IT Helpdesk
Phone, email, or chat with under 30-minute response. You talk to someone who already knows your setup — not a rotating call centre.
Microsoft 365 Management
Full administration of your tenant: user accounts, email, Teams, SharePoint, OneDrive, licensing, and security configuration.
Cybersecurity
MFA, Conditional Access, Microsoft Defender, anti-phishing policies, email authentication (SPF, DKIM, DMARC), and data loss prevention.
Device Management
Every laptop and phone enrolled in Intune — encrypted, managed, and remotely wipeable. Windows, Mac, iOS, and Android.
Onboarding & Offboarding
New starters get a fully configured device on day one. Leavers have access revoked and data archived the same day.
Proactive Monitoring
We catch problems before your team notices. Disk space, failed updates, security violations, and unusual sign-in activity — all monitored and acted on.

Frequently Asked Questions
Outsourced IT support means handing your day-to-day technology management to an external provider instead of hiring in-house. You get a dedicated team covering helpdesk, cybersecurity, device management, cloud administration, and monitoring for a predictable monthly fee.
Break-fix companies only show up when something is already broken. You call, they fix it, you get a bill. Outsourced IT support is proactive — we monitor your systems, patch devices, manage security, and prevent issues before they cause downtime.
No. You retain full ownership of all accounts, data, and systems. We manage them on your behalf with complete transparency. You get admin access to everything and we document every change.
Most transitions are completed within a week. We handle credential handovers, audit existing configurations, fix security gaps, enrol devices, and ensure zero downtime during the switch.
No. We work on rolling monthly agreements. If we're not delivering value, you can leave. We'd rather earn your business every month than lock you in.
We focus on small businesses with 1 to 50 staff. That's our sweet spot — big enough to need proper IT, small enough that the large outsourced IT providers won't give you the time of day.
