Commenting on the reaccreditation of CPIH as a National Statistic, ONS Director General Jonathan Athow said:

“This is an important step in our plans to improve the UK’s inflation statistics.

“CPIH is our lead measure of inflation and offers the most comprehensive picture of how prices are changing in the economy.

“We are building a suite of measures as an alternative to the RPI. We will continue to produce RPI for legacy uses. However, the RPI is a flawed measure of inflation with serious shortcomings and we do not recommend its use.”
