A total of 5,964 telephone interviews were conducted with household water and sewerage bill payers across England and Wales between the 24 September 2015 and 12 January 2016. At least 200 interviews were carried out with customers of each Water and Sewerage Company (WaSC) and 150 with customers of each Water only Company (WoC).
For inclusivity, 424 interviews were conducted with households which do not have a landline or only have a landline for broadband (mobile only households); the remaining 5,540 were conducted with households using a landline.
Analysis has been undertaken at a total sample level (England and Wales combined), by country (England vs. Wales) and by water company. This is a move away from previous reporting where the analysis was at WaSC regional level rather than company level.
