Packaging price review — example
How should we assess a packaging supplier’s proposed price increase?
What changed
In this fictional scenario, a packaging supplier has requested a price increase without a cost breakdown.
USER ASSERTED
The ONS publishes consumer and producer price indices. Selecting an appropriate series and period is part of checking the evidence.

Why it matters
A proposed increase needs to be compared with the contract, demand and the supplier’s own cost breakdown. An economy-wide index alone cannot establish whether the supplier’s request is justified.
Options
Draft options to consider, not approved instructions.
Request the missing cost breakdown
Understand which costs the supplier says have changed before judging the increase.
Review the contractual position
Check the mechanism and timing before agreeing a response.
Compare relevant evidence
Use the appropriate input series alongside demand and specification changes.
