Facilities
Cleaning, waste collection, pest control, maintenance contracts.
Why this category drifts
Facilities contracts are the most likely of anything you buy to have rolled over automatically for years with an annual uplift nobody negotiated.
What we watch
ONS services producer prices for cleaning and for waste collection and treatment.
Alongside your own invoices — a supplier's own price rise is better evidence than any national average, and it is the one thing no index can tell you.
Why the quotes are hard to compare
These are priced per visit, per bin, per square metre or per month, which makes two quotes look incomparable until they are all put on the same basis.
CostSpring converts every quote to a landed cost per unit you actually use, keeps the caveats attached to the number they qualify, and tells you what the gap is worth in the rhythm you order in.
Where to start
Add the two or three lines you suspect have not been looked at in a while. If nothing is worth acting on, you will be told that too — an alert nobody needs is worse than no alert.
