HIRE IT SUPPORT
STAFF LONDON
Everything London SMEs need to know about finding, hiring, and retaining IT support staff — including costs, risks, and when managed IT is the better option.
What SMEs discover when
they hire IT staff
Average time-to-hire: 8–14 weeks
London IT roles attract high candidate volumes but specialist roles — security, network, cloud — can take 4–6 months to fill.
Average IT staff tenure: 2–3 years
High turnover means you are recruiting again sooner than expected, repeating the cost and disruption each time.
Skills gaps are expensive to fill
One generalist IT hire cannot cover networking, security, cloud, helpdesk, and compliance simultaneously. You end up needing multiple hires.
Agency fees add 15–20% to salary cost
For a £45,000 hire, that is £6,750–£9,000 in one-off recruitment fees — before the employee starts.
Holiday and sick cover falls on the business
A single IT hire means 28+ days of uncovered support per year, plus sick leave — often during critical periods.
Institutional knowledge walks out the door
When your IT person leaves, documented processes are rarely handed over cleanly — creating costly knowledge gaps.

Hiring IT staff in London —
questions answered
Q.Where can I find IT support staff in London?
IT support staff in London can be found through specialist IT recruitment agencies (Reed Technology, Hays Technology, CPS Group), direct LinkedIn advertising, or general job boards (Indeed, CV-Library, Totaljobs). However, most London SMEs considering hiring IT staff should also evaluate managed IT support as an alternative — it is typically 60–70% cheaper than a direct hire and provides broader technical coverage without the recruitment risk or HR overhead.
Q.How long does it take to hire IT support staff in London?
Average time-to-hire for IT support roles in London is 8–14 weeks for generalist support engineers, and 4–6 months for specialist roles (network engineers, security analysts, cloud architects). Once hired, a 3-month probation period is standard before you can rely on the person fully. This compares with 24–48 hours to onboard a managed IT provider.
Q.What should I look for when hiring an IT support person for my business?
For a small business IT hire, look for: CompTIA A+ or Network+ certification for hardware/networking basics; Microsoft certifications (MS-900, AZ-900) for cloud familiarity; experience with your specific software stack; strong communication skills for user-facing support; and references from similar-sized businesses. However, be aware that one person cannot be expert in every IT domain — managed IT gives you a full team of specialists for a similar or lower total cost.
Q.Is it better to hire IT staff or use a managed IT service?
For most London SMEs under 150 staff, managed IT is the better commercial decision. The true cost of one IT engineer hire (salary + NI + pension + equipment + training) is £47,000–£68,000/year. Managed IT for a 20-person business costs £14,000–£24,000/year — providing a full team, 24/7 monitoring, and built-in cyber security at a fraction of the cost. Hiring in-house makes more sense at 150–200+ users or where bespoke systems require dedicated permanent resource.
Q.Can I hire IT staff part-time or on a contract basis?
Yes — part-time IT support staff and IT contractors are available in London. A part-time IT support person (2–3 days/week) typically costs £600–£900/day or £18,000–£27,000 for a part-time contract, plus agency margin. IT contractors for project work (infrastructure upgrades, migrations, security projects) typically cost £350–£600/day. For ongoing operational IT support, managed IT often remains more cost-effective than part-time staff due to coverage breadth and out-of-hours monitoring.
Q.What IT roles should I consider hiring for a 20-person business?
For a 20-person London SME, a single in-house hire would typically be an IT Support Engineer or IT Manager generalist — covering helpdesk, device management, network troubleshooting, and Microsoft 365 admin. However, this one person will not have specialist cyber security, cloud architecture, or compliance expertise. Most 20-person businesses are better served by a managed IT provider who provides all these specialisms as part of a monthly package, rather than a single generalist hire who becomes a bottleneck.
