1. The same complaints keep coming back
If the same washroom or kitchen issues are raised month after month, the contract is not resourced or supervised properly.
2. Nobody can show you an audit
If there are no scored audits, there is no evidence the specification is being met.
3. You don't have a specification
If the contract is a price and a few lines of description, you can't hold anyone to account. Retendering is the moment to write one.
4. Your building has changed
New floors, hybrid working or a change in use can leave the contract cleaning the wrong things at the wrong times.
5. The price only ever goes up
Wage rises are legitimate, but if the price rises while the hours and standards don't, it is time to test the market.
Running a fair retender
Write the specification, invite three or four contractors to survey and price it, compare hours as well as price, and check how each will handle TUPE. See switching cleaning contractors.
