What Is an Agency Retainer?

WHITO GLOSSARY · MEASURED DEFINITIONS

A recurring monthly fee reserving an agency’s ongoing work. UK marketing retainers typically cost £1,250 to £3,500 a month for a single channel and £3,500 to £16,750 for full service, both up more than 30% on 2023.

The number: UK Agency Retainer Benchmark.

What it means in practice

The mistake is signing a retainer without asking how many days of work it contains. A fee with no day count is a fee you cannot compare with anything.

Run the days-a-month test: divide the fee by a published day rate and see how many days it could possibly hold. Then ask the agency how many days you actually get.

Whito stage: Build. Buy this once the foundations are set, not before.
