Across multiple policy domains, Westminster has developed a reliable method for avoiding action: publish an inflated, implausible cost estimate and use it to declare reform unaffordable and shut down debate. The tactic is so entrenched that it now shapes debates on infrastructure, utilities, education, climate adaptation, and even measurement policy. The Department for Transport’s wildly exaggerated claims about the cost of converting road signs to metric were later dismantled by FOI evidence showing real‑world conversions were far cheaper. Today, the same pattern is visible in the £100bn headline figure used to deter discussion of water‑industry nationalisation. How are these inflated numbers produced and why do they persist? Where else are they used to avoid necessary action?

Ever since the court cases of the so-called Metric Martyrs about a quarter of a century ago, the UK’s metrication programme has been stalled. It has been in limbo ever since: officially ongoing, practically stalled, politically untouchable. It is not just a story about units of measurement. It is a case study in how Westminster creates long‑running policy messes, performs the rituals of action, avoids responsibility, and ultimately moves on without ever resolving the underlying problem.

Metrication is the perfect example of Westminster’s “Create a Mess, Go Through the Motions, Make Excuses, Move On” pattern. In recent years, this pattern has occurred across multiple domains—from higher education to HS2, from austerity to water regulation. Metrication is a clear example of a deeper Westminster habit: botched policy reform without structural completion. This article maps that pattern and shows how metrication illustrates it perfectly.
