Since privatisation in 1989 the water industry has invested approximately £4.9 billion per year on average (in 2016/17 prices) in both water supply and wastewater infrastructure.

Ofwat calculates that between the years of 1989 to 2018 the following amounts have been invested in water supply:

Ofwat has also calculated the 1988 total capital expenditure for water and wastewater combined as £3.7 billion. A breakdown of capital expenditure between water supply and wastewater infrastructure is not available pre-1989.

These figures are in 2016/17 prices using RPI financial year average.
