It is firms' forecast of economy-wide consumer inflation 1 year (12 months) ahead, not their own price plans. Respondents are chief financial officers (CFOs) and other senior finance leaders at UK businesses with 10 or more employees. The Bank of England (BoE), the UK central bank, runs it with King's College London and the University of Nottingham.
The sample covers private and third-sector employers across industries and sizes, mirroring the UK business population. It does not measure actual inflation, which the Office for National Statistics reports, nor household expectations. The publisher states no threshold for it; the Government's 2% target applies to actual inflation, not to this reading.
