What is outsourced IT support
for London businesses?
Outsourced IT support in London means contracting an external IT company to manage your entire technology operation on a fixed monthly fee — replacing or supplementing internal IT staff. Rather than employing your own IT team, you engage a specialist IT provider who takes full responsibility for your IT environment.
For London SMEs, outsourced IT support typically includes: unlimited helpdesk for all users, 24/7 proactive monitoring (catching issues before they become outages), Microsoft 365 management, cyber security (antivirus, email filtering, dark web monitoring), patch management, and on-site engineers available across London without callout fees.
The key difference from break-fix IT support is that outsourced IT support is proactive — your provider monitors and maintains your IT continuously, rather than waiting for you to report a problem. This dramatically reduces downtime, security incidents, and the unpredictable cost of reactive IT fixes.

Benefits of outsourced IT support
for London businesses
70–90% cheaper than in-house
A full outsourced IT support team costs a fraction of equivalent in-house headcount — no salary, NI, pension, holiday, or training costs. Most London SMEs save £30,000–£60,000/year.
Full team, not one person
Access a helpdesk engineer, Microsoft specialist, security analyst, and network engineer — rather than one generalist who can't cover all bases and is one resignation away from leaving you exposed.
24/7 monitoring — not office hours
Most IT failures happen outside office hours. Outsourced IT support includes 24/7 automated monitoring — catching and resolving issues before your team arrives in the morning.
Cyber security included
Cyber security managed as part of your outsourced IT support — EDR, email filtering, MFA, dark web monitoring, and Cyber Essentials certification. Not left for you to self-manage.
No single point of failure
When your in-house IT person is on holiday, sick, or resigns — you're exposed. With outsourced IT support, the team continues regardless. No coverage gaps, no emergency recruitment.
Scales with your London business
Per-user pricing means your IT cost grows proportionally as you hire — no need to recruit a new IT person every time you reach a headcount milestone. Add users, not headaches.

What London businesses say about
Coreitech outsourced IT support
"We outsourced IT to Coreitech when our IT manager left. Two years on, we'd never go back in-house. The coverage, expertise, and response times are all better — and we pay less per month than we paid in salary. Best decision we've made."
"IT outsourcing solved our scaling problem. Every time we hired, IT became harder to manage with one person. Now we just add users to the contract. Simple, predictable, and no IT recruitment headaches."
"The 48-hour transition was painless. Coreitech handled everything with our previous IT provider, and on day three we had better monitoring and faster outsourced IT support than we'd had in five years."

questions answered
Q.What is outsourced IT support in London?
Outsourced IT support in London means contracting an external IT company to manage your technology — replacing or supplementing internal IT staff. For London SMEs, this typically means a fully outsourced IT department: unlimited helpdesk, 24/7 monitoring, Microsoft 365 management, cyber security, and on-site engineers — all on a fixed monthly per-user fee. Coreitech provides outsourced IT support for London businesses from £25/user/month, with a 15-minute critical response SLA.
Q.How much does outsourced IT support cost in London?
Outsourced IT support in London costs £25–£60/user/month as a managed service. For a 20-person London business, that's £500–£1,200/month all-inclusive. Compare this to a single in-house IT hire in London — typically £45,000–£70,000/year in salary alone (£225–£350/user/month for a 20-person team), before employer NI, hardware, pension, or training costs. Coreitech's fully outsourced IT support starts from £25/user/month.

Q.What is the difference between outsourced IT support and managed IT support?
The terms are interchangeable in the London SME context. "Outsourced IT support" emphasises replacing an internal IT function with an external provider. "Managed IT support" or "managed service provider (MSP)" describes the same proactive, fixed-fee model. Both mean an external IT company takes full responsibility for your IT environment on a monthly per-user contract.
Q.Should I outsource IT support or hire in-house in London?
For most London SMEs with fewer than 150 users, outsourced IT support is more cost-effective than in-house hiring. A single IT hire in London costs £45,000–£70,000/year. Outsourced IT support from Coreitech costs £25–£50/user/month — providing a full specialist team (helpdesk, Microsoft, security, network), 24/7 monitoring, and no single point of failure. In-house becomes viable at 150–200+ users when a full internal IT team is warranted.
