Background
The Water Industry Commission for Scotland (WICS) was formed on 1 July 2005 following the amendment of the Water Industry (Scotland) Act 2002 by the Water Services etc. (Scotland) Act 2005. The Commission is funded through a levy on Scottish Water and licence fees.
Statutory duties are to:
- promote the interests of Scottish Water’s customers, having regard to the interests of current and future customers
- ensure that customer charges reflect the lowest reasonable overall cost for Scottish Water to deliver the Scottish Ministers’ Objectives for the water sector
- comment on Scottish Water’s reporting of its performance, challenging Scottish Water to become more efficient and sustainable and
- facilitate the entry of retail water and sewerage providers that wish to supply non-household customers in Scotland
WICS support both the Scottish Government’s vision of ensuring that Scotland is a Hydro Nation and the jointly agreed vision for the Scottish water sector. This is that the sector will be “admired for excellence, secure a sustainable future and inspire a Hydro Nation”. In doing so they meet their obligations under the Water Resource Act 2013.
WICS is made up of around 25 people, comprising economists, strategists, analysts, communicators and support staff. The board provides leadership, direction and support to ensure that WICS delivers its functions effectively and efficiently.
