Energy and Water: Nationalisation

Question

To ask the Chancellor of the Exchequer, whether she has made an estimate of the cost of nationalisation of (a) the water industry and (b) energy utility companies.

Answer

DEFRA has estimated the cost of nationalising the water industry. This is set out in a technical note that can be found here: https://www.gov.uk/government/publications/nationalising-the-water-sector-how-we-assessed-the-cost/nationalising-the-water-sector-how-we-assessed-the-cost.

The government has not assessed the value of the entire energy system. Ofgem’s latest energy network price control set out potential investment by network companies and can be found here: RIIO-3 Final Determinations for the Electricity Transmission, Gas Distribution and Gas Transmission sectors | Ofgem
