Two suppliers, two invoices and a lot of handovers. Here is why putting security and cleaning under one contract saves time, keys and money.
Security and cleaning have more in common than most people think. Both usually happen when your building is empty. Both need someone to open up, lock up and hold keys. And both are often bought from two different companies that never speak to each other.
The hidden cost of two suppliers
When security and cleaning are run separately, the gaps show up in small ways. A cleaner needs letting in at 6am, so someone gives them a key. An officer notices a leaking tap but it is not their job to report it. Two account managers, two invoices, two sets of contracts to renew. None of it is dramatic, but it adds up.
What changes with one contract
- Fewer keys in circulation. Keyholding officers let the cleaning team in and lock up after them, so your keys stay under one company’s control.
- One point of contact. A single account manager who knows your building, your hours and your people.
- Better reporting. Officers flag spills and damage; cleaners flag open windows and faulty locks. Everything lands in one report.
- Simpler admin. One monthly invoice and one contract to review.
Is it right for every site?
Not always. If you only need a single evening lock-up, or a one-off deep clean, you can book either service on its own. Combining makes most sense for offices, schools, retail units and managed buildings that need both regularly.
