In-house cleaning vs external provider: which option for a local authority?

Many local authorities face the question: should we clean our buildings in-house (municipal staff) or outsource to a private provider? Each option has its advantages. In-house ensures social control and team stability. Outsourcing brings flexibility, expertise, and budget control. This data-driven comparison helps decide based on 12 key criteria observed in 500 French municipalities.

Municipal in-house strengths

  • Full social control (public collective agreement)
  • Team stability (tenured civil servants)
  • Intimate knowledge of buildings and staff
  • Immediate responsiveness (on-site staff)
  • No heavy public procurement procedure

Municipal in-house weaknesses

  • 20-40% higher annual cost than outsourcing
  • Difficulty adjusting staff numbers (civil service status)
  • Turnover on retirements (closed recruitment pool)
  • Low technical specialization (limited external training)
  • Often inferior equipment (limited capex budget)
  • Difficulty handling exceptional peaks (events, deep cleaning)

Our verdict

Both options have their legitimacy depending on context. In-house remains relevant for very small municipalities (< 2,000 inhabitants) where volumes are insufficient to interest a serious provider, and for local authorities with strong social culture. Outsourcing is economically unbeatable from 5,000 m² upwards: 25-35% annual savings, operational flexibility, specialized expertise, renewed equipment. The optimal compromise for many medium-sized local authorities: in-house for 1-2 emblematic buildings (central town hall) + outsourcing for the rest of the portfolio. In either case, the choice must be rigorously costed on full costs (salaries + charges + management + equipment + training + capex).
