CPIH is the most comprehensive measure of inflation. It extends CPI to include a measure of the costs associated with owning, maintaining and living in one's own home, known as owner occupiers' housing costs (OOH), along with council tax. This dataset provides CPIH time series (2005 to latest published month), allowing users to customise their own selection, view or download.

This dataset includes the 24 month forecast of Capacity Market monthly payments. The forecast monthly CM costs are estimated as the Auction Acquired Capacity Obligation (kW) × Adjusted Capacity Cleared Price (£/kW/year) × Monthly Weighting Factor. The capacity obligation is valued at the relative CM auction Capacity Cleared Price (CCP) and is adjusted for UK Consumer Prices Index (CPI) for T-4 Auctions only. “CPI” means the UK Consumer Prices Index (All Items) published monthly by the Office for National Statistics.
