How to choose an IT support
company in London
Choosing an IT support company in London is one of the most important technology decisions your business will make. Unlike most suppliers, your IT company works alongside your team every single day. Here are the eight things to verify before signing.
Verify their SLA in writing
Any reputable IT support company in London will guarantee response times in your contract — not just "aim for" them. The industry standard for critical (P1) issues is 15 minutes. Ask to see the exact SLA wording before signing. If they can't provide it, walk away.
Check what's actually included
Many London IT companies advertise a low per-user price that excludes cyber security, on-site support, or Microsoft 365 management. Ask specifically: is EDR antivirus included? Are on-site visits included? Is Microsoft 365 admin included? Get it in writing. The real cost is what matters.
Verify their Microsoft Partner status
Over 90% of London SMEs use Microsoft 365. Your IT support company should hold current Microsoft Partner accreditation — verifiable on Microsoft's public partner directory, not just claimed on their website. This ensures genuine expertise, not just familiarity.
Check their Cyber Essentials certification
Would you trust an IT security company that hasn't secured their own business? Any credible London IT support company should hold current Cyber Essentials or Cyber Essentials Plus certification. Coreitech is CE Plus certified — independently verified by IASME.
Read reviews for your business size
Reviews from 500-person enterprises don't tell you much if you're a 30-person law firm. Filter Google and Trustpilot reviews by looking for businesses similar to yours. Check the most recent reviews — not just the rating — and look for mentions of response times and account management quality.
Understand the contract terms
Avoid IT support companies that lock you into 3-year auto-renewing contracts with punitive exit clauses. The best IT support companies in London offer 12-month or monthly rolling contracts. Ask specifically about the exit notice period and any penalties before signing.
Ask about the onboarding process
A professional IT support company in London will have a defined onboarding process — site visits to document your environment, asset tagging, introduction to your account manager, and a clear migration timeline. If they can't describe their onboarding process, that's a red flag.
Meet the engineers, not just the sales team
Before signing, ask to meet the engineers who will actually support you day-to-day. Specifically ask to speak with the service desk manager and your nominated account manager. Clear communication in plain English — without excessive jargon — is essential for a productive long-term relationship.
10 red flags when choosing an
IT support company in London
If your prospective IT support company shows any of these warning signs, reconsider before signing.

Questions about IT support
companies in London
Q.What is an IT support company?
An IT support company provides managed technology services to businesses — covering helpdesk support, network management, cyber security, cloud services, and strategic IT consultancy. London IT support companies typically offer either break-fix support (pay per incident) or managed IT support (fixed monthly fee covering unlimited support). Most London SMEs use managed IT support for cost predictability and proactive monitoring.
Q.How much does an IT support company in London cost?
A managed IT support company in London typically charges £25–£60 per user per month for a comprehensive all-inclusive package. Beware of prices below £20/user — these almost always exclude cyber security, on-site support, or Microsoft 365 management, making the real cost higher. Coreitech charges from £25/user/month (Standard) and £50/user/month (Advanced), with no hidden charges.
Q.What should an IT support company in London include?
A proper IT support company in London should include: unlimited helpdesk calls, 24/7 system monitoring, on-site engineer visits, cyber security (EDR antivirus, email security, MFA), patch management, and Microsoft 365 administration — all within the monthly per-user fee. Any provider that charges extra for cyber security or on-site visits is not offering a genuinely all-inclusive service.
Q.How do I switch IT support companies in London?
Switching IT support companies in London is straightforward when handled professionally. The process typically takes 4–8 weeks: (1) give notice to your existing provider per your contract terms; (2) your new IT company conducts a full environment audit and documents all systems; (3) on a defined go-live date, monitoring and management transfers with minimal disruption. Coreitech manages the entire transition for you — including negotiating with your outgoing provider if needed.
Q.What is the difference between managed IT support and break-fix IT support?
Break-fix IT support means you call an IT company when something breaks and pay per incident or per hour. Managed IT support means you pay a fixed monthly fee and the IT company proactively monitors, maintains, and supports your systems — preventing issues before they occur. For London SMEs with more than 5 users, managed IT support almost always works out cheaper, more reliable, and less disruptive than break-fix.
Q.Do I need a local IT support company in London?
For most London businesses, a local IT support company is preferable — particularly for on-site support, equipment installation, and office moves. A London-based IT company can have an engineer at your office within 2–4 hours for critical hardware issues, whereas a national provider based outside London may charge travel time or have slower response. Coreitech is based in London Bridge SE1 and covers all London boroughs with same-day on-site capability.
Q.What size businesses do London IT support companies serve?
Most established IT support companies in London serve businesses ranging from 5 to 500 users. Coreitech specialises in London SMEs from 5–200 users — the sweet spot where businesses need professional IT support but don't have a dedicated internal IT department. We also offer co-managed IT support for businesses that have internal IT staff but need additional specialist resource.
Q.How quickly should an IT support company respond?
The industry standard for a managed IT support company in London is: critical (P1 — system down) 15 minutes or less; high (P2 — major function unavailable) 2 hours; medium (P3) 4–8 hours; low (P4) next business day. These should be contractual guarantees, not aspirational targets. Coreitech's critical SLA is 15 minutes — guaranteed in your contract.
