How could uncertainties in ONS data affect Ofgem's energy price regulation?
Uncertainty in ONS data could affect Ofgem's energy price cap inputs The use of Office for National Statistics (ONS) survey data in economic modeling, as detailed in the report, is subject to significant caveats. The report states that survey uncertainty, revisions to official data, and updated economic models mean the results should not be compared directly with previous editions. This raises questions about the consistency and reliability of the underlying ONS data. Since Ofgem utilizes official ONS data on CPI and inflation rates as inputs for setting the energy price cap and regulating the market, any systemic uncertainty in that data could impact its regulatory decisions.

How it reaches Ofgem
-
A report by the Fraser of Allander Institute at the University of Strathclyde estimates that approximately 49,200 full-time equivalent jobs exist in the Scottish renewables sector. The report, which was commissioned by Scottish Renewables, is based on Office for National Statistics survey data and a model of the Scottish economy. The figures are estimates and are subject to revision as more survey responses are received.

Why it matters
For Ofgem, the integrity of official statistics is paramount, as its regulatory decisions—such as setting the energy price cap—are directly informed by data on inflation and consumer prices. If the foundational ONS data is subject to significant methodological revisions and uncertainty, it introduces a layer of risk into the regulatory process, potentially leading to less stable or less accurate market interventions.
This issue is not unique to energy regulation. Many government bodies and economic institutions, including the Bank of England and HM Treasury, rely on ONS data for critical functions like monetary policy and GDP reporting. The reliance on a single statistical body means that any perceived weakness in data methodology or consistency has wide-ranging implications for economic governance across the UK.
