The thirteenth wave of data was collected between 18 and 29 March 2015 using face-to-face in-home interviews with a representative sample of 1,981 UK households. The March 2015 questionnaire was in most respects the same as that used in March 2012 (wave 1). Where questions had been rephrased in July 2012 (wave 2) the revised version is used here; some small adjustments were made to align questions with other DECC tracking surveys.
