Why Frequency Matters
Cleaning frequency is the single biggest driver of both cleaning quality and cleaning cost. Clean too infrequently, and your premises look neglected, hygiene suffers, and surfaces deteriorate faster. Clean too frequently, and you overspend on a service that could be delivered more efficiently. The right frequency balances hygiene, appearance, asset protection, and budget — and it varies dramatically by industry.
This guide provides industry-specific benchmarks based on our experience delivering contract cleaning across Ireland. Use it to assess your current cleaning schedule, develop a new cleaning specification, or evaluate whether your current provider is delivering the right level of service.
