— What Are IT Support Companies?

What do IT support companies
in London actually do?

IT support companies in London (also called managed IT providers or MSPs) manage your business technology on your behalf — from daily helpdesk support and 24/7 monitoring to Microsoft 365 management, cyber security, and strategic IT planning. Most London IT support companies charge a fixed monthly fee per user, giving you predictable costs and unlimited support.

The London IT support market is large and varied. You'll find everything from one-person operations in Outer London to large national MSPs with hundreds of engineers. For most London SMEs (5–200 users), the best IT support companies combine local on-site capability (engineers who can be in your office within the hour), Microsoft 365 expertise, and built-in cyber security — all for a transparent monthly fee.

Coreitech is based at London Bridge SE1 and covers all 32 London boroughs. Our engineers reach Central London (City, West End, Canary Wharf, Southwark, Shoreditch) within 30–60 minutes on-site — and our helpdesk responds to P1 critical issues within 15 minutes, contractually.

— How to Choose

6 things to check when comparing
IT support companies in London

Contractual Response SLA

Any reputable IT support company in London will commit a guaranteed SLA in writing — not "we aim to respond in 15 minutes" but a contractual obligation. P1 critical: 15 minutes. P2 high: 2 hours. Ask for this before signing.

Cyber Security Included

The best IT support companies in London include EDR, email filtering, patch management, MFA, and dark web monitoring in the base price. If security is an add-on, the headline price is misleading.

Microsoft 365 Expertise

Over 90% of London SMEs use Microsoft 365. Your IT support company should fully manage Teams, SharePoint, Intune MDM, Entra ID, and Defender — and hold current Microsoft Partner status.

On-Site Engineers Included

Remote support is fine for most issues — but on-site engineers should be included in the monthly fee, not charged per visit. Ask directly about callout fees before signing with any London IT company.

Transparent Per-User Pricing

Per-user pricing with no ticket limits, no hidden charges, and no call-out fees is the gold standard. Get the full all-inclusive price in writing. If they won't publish pricing, ask why.

UK-Based Engineers

Many IT support companies in London use offshore first-line helpdesk. Ask directly: where are your engineers based? London-based engineers understand local business context and can provide on-site response.

— Pricing

How much do IT support companies
charge in London?

IT support companies in London typically charge £25–£60 per user per month for a comprehensive managed IT package. Prices vary based on what's included — and many providers charge significantly more when you add up all the extras.

Be wary of IT support companies charging below £20/user — at that price point, cyber security, on-site engineers, and Microsoft 365 management are almost always excluded, making the real cost much higher once extras are added.

£10–£20/user/monthRemote-only helpdesk — cyber security, on-site & M365 typically excluded
£25–£35/user/monthStandard all-inclusive — helpdesk, monitoring, security, patching
£40–£60/user/monthAdvanced — full Microsoft 365 management, SOC monitoring, dedicated AM
£60+/user/monthEnterprise-grade — complex multi-site, compliance-heavy environments

What London businesses say about
Coreitech as an IT support company

"We compared four IT support companies in London before choosing Coreitech. They were the only one to publish pricing, provide a contractual SLA, and include cyber security in the base price. Two years in — completely the right call."

CEO
Financial services, Canary Wharf

"As an IT support company, Coreitech stands out for being proactive. Our previous IT company just reacted to problems. Coreitech's monitoring team spotted and fixed three issues last month before anyone in the office noticed."

Operations Director
Law firm, City of London

"We moved from a larger IT support company to Coreitech — best decision we made. Faster response times, a named account manager who knows our systems, and the same price we were paying before for far less."

questions answered

Q.What IT support companies are in London?

There are hundreds of IT support companies in London, ranging from small one-person operations to large MSPs. Well-regarded London IT support companies for SMEs (5–200 users) include: Coreitech (London Bridge SE1, from £25/user/month, 4.9★ Google), Totality Services (Vauxhall, 4.9★ Feefo), Wavex Technology (Central London, since 1998), Akita (London & South East), TechQuarters (Central London), and Fifosys (London & UK). Each has different strengths — evaluate on response SLA, pricing transparency, Microsoft credentials, and sector experience.

Q.How do I choose an IT support company in London?

When choosing an IT support company in London, compare on five criteria: (1) Response SLA — get it in writing, contractually; (2) What's included — cyber security, on-site visits, and Microsoft 365 management should be standard; (3) Contract terms — avoid 3-year auto-renewing agreements; (4) Reviews — check Google Maps, Trustpilot, and Clutch for recent reviews from businesses your size; (5) Microsoft accreditation — verify on Microsoft's partner directory.

Q.How much do IT support companies charge in London?

IT support companies in London typically charge £25–£60 per user per month for comprehensive managed IT support. Be cautious of prices below £20/user — these almost always exclude cyber security, on-site engineers, or Microsoft 365 management. Coreitech charges £25/user/month (Standard) or £50/user/month (Advanced) with everything included — no hidden extras.

Q.What is the difference between IT support companies and managed IT providers?

The terms are largely interchangeable for SMEs. An IT support company typically refers to a provider that handles your IT reactively — fixing things when they break. A managed IT provider (MSP) takes a proactive approach: 24/7 monitoring, patching, security management, and strategic IT advice, all for a fixed monthly fee. Most reputable IT support companies in London now operate as MSPs — offering both reactive helpdesk and proactive managed services.

Q.What questions should I ask IT support companies in London?

Key questions to ask IT support companies in London: (1) What is your exact SLA for P1 critical incidents — in writing? (2) Is cyber security (EDR, email filtering, MFA) included in the base price? (3) Are on-site engineer visits included or charged per visit? (4) Do you hold current Microsoft Partner accreditation? (5) What is the contract length and exit notice period? (6) Will I have a named account manager? (7) Where are your helpdesk engineers based?

Q.Are there IT support companies in London that don't require a long contract?

Yes. Several London IT support companies offer monthly rolling contracts, including Coreitech. Monthly rolling contracts are the most flexible option — you can leave with 30 days' notice if the service isn't right. Some IT companies offer 12-month terms with flexible exit clauses. Avoid any IT support company in London that requires a 36-month contract with auto-renewal and punitive early termination fees.
