1 Annual percentage change date period is June 2014 to June 2015.
The price changes in the local authorities shown are based on the price per unit area of the properties in the sample rather than the mix-adjusted methodology used for the 13 regions. The average price per square foot in each of the local authorities is grossed up by the average square footage in a particular region to arrive at an average house price. Unlike Nationwide’s main index, this methodology does not take into account the different mix of properties transacted and is therefore a simplification.
Local authority figures are therefore not directly comparable with regional prices. Samples are substantially smaller than at a regional level and figures should not be relied upon for any critical application. Due to greater volatility, prices are smoothed over two quarters.
