Benefits for Economic Insight

• We provided training on econometric measures of efficiency, putting the organisation in a stronger position to secure further work with water companies.
• We also advised on accurately measuring retail efficiencies, a new element in the price determination.

Guiding Ofwat

• We commented on Ofwat’s Cost assessment for PR19: a consultation on econometric cost modelling.
• We also provided technical advice on how to model a company’s dual service customers.

Supporting water companies

• We helped to produce the retail cost models for Affinity, Bristol, Wessex and Thames water companies.
• We similarly supported Yorkshire Water around cost efficiency modelling.
