Azure Managed Services vs In-House IT: 2026 Cost Analysis
For a 150-person company with cloud infrastructure on Azure, the question of whether to manage it in-house or outsource to a managed service provider comes down to a specific cost and capability comparison. This analysis uses real 2026 market rates.
In-House IT Team Cost (150-person company)
To adequately cover Azure infrastructure management, security monitoring, end-user support, and application support, a 150-person company needs at minimum: IT Manager/Head of IT: £65,000–£85,000/year. Azure/Cloud Engineer (mid-senior): £55,000–£75,000/year. IT Support Engineer (x2): £28,000–£38,000/year each. Security Analyst (part-time or shared): £20,000–£35,000/year equivalent.
Total salary cost: £196,000–£271,000/year. With employer NI (13.8%), pension (5%), benefits, training, and recruitment amortisation (typically 20% on top): fully-loaded cost of £245,000–£339,000/year. Azure spend (at this company size): typically £3,500–£8,000/month = £42,000–£96,000/year. Total in-house IT cost: £287,000–£435,000/year.
Azure Managed Services Cost
A Techseria Azure managed services engagement for a 150-person company covers: Infrastructure management (VM patching, scaling, availability monitoring), Security monitoring (Azure Sentinel, Defender, identity management), Backup and DR management, Azure cost optimisation (reserved instances, rightsizing), End-user support (L1/L2 helpdesk), Application support for core business apps.
Managed service fee: £4,500–£9,000/month = £54,000–£108,000/year. Azure spend (same as in-house, but typically 15-25% lower due to active optimisation): £31,500–£72,000/year. Total managed services cost: £85,500–£180,000/year.
The Comparison
In-house IT total: £287,000–£435,000/year. Azure managed services total: £85,500–£180,000/year. Saving with managed services: £100,000–£255,000/year. Mid-point annual saving: approximately £160,000.
What the Cost Comparison Misses
Speed of incident response. An in-house IT engineer can physically be present in your office. A managed service provider responds remotely — for most Azure incidents this is equivalent, but for hardware or local network issues, physical presence matters. Institutional knowledge. In-house engineers accumulate deep knowledge of your specific environment over time. Managed service teams have this too (a good MSP assigns a named engineer to your account), but there is more turnover risk. Control and visibility. Some companies feel more comfortable with an employee who is accountable only to them. A managed service contract creates accountability through SLAs, which some find more reliable than employment management.
