IT Outsourcing Cost UK: In-House vs MSP vs Co-Managed IT
IT outsourcing cost in the UK is published at £40 to £150 per user per month, while the alternative is quoted in salaries — and the two are almost never compared honestly. This guide prices one 50-user business three ways, from £42,000 a year fully outsourced to £106,897.94 fully in-house, using HMRC’s 2026/27 employer thresholds, the ITJobsWatch salary and contract indices, four suppliers’ published G-Cloud rate cards and Acas guidance on TUPE. It finds the exact headcount at which co-managed IT overtakes a full outsource, shows why one round-the-clock seat needs 5.1454 employees, and ends with a three-year table in which the three models are 2.5980x apart.
