October 2019 Trust in water Service delivery report 2018-1 9 www.ofwat.gov.uk Service delivery report 2018-19 Introduction At the 2014 price review (PR14) we required water and wastewater companies (‘companies’) to develop plans based on engaging with their customers about the: • services customers wanted their company to deliver over the long term (‘outcomes’); • specific levels of service they expected companies to deliver (‘performance commitments’); and • value of any outperformance payments and underperformance payments (‘outcome delivery incentives’ or ‘ODIs’) companies would incur for exceeding or failing them. In PR14 final determinations, we set the price, investment (expenditure) and service package that companies deliver and customers receive between 2015 and 2020. Each company must report annually on their expenditure and outcome delivery in an annual performance report (APR). The service delivery report provides comparative information on total expenditure and outcomes delivered to customers reported by the 17 largest companies within England and Wales. This report provides comparative information on important areas of performance and is intended to supplement the more detailed information in companies’ APRs. This information will help us – and stakeholders such as customer groups, environmental groups and investors – to hold companies to account. We recently published ‘Time to act, together: Ofwat’s strategy’. One of the objectives of our new strategy is to turn the data we hold, along with information from other sources, into insight. For 2018-19, we have revised the approach to reporting on performance in the service delivery report to better illustrate the industry’s performance and trends over time. Key changes that we have made are: • providing comparative ranking of companies’ performance; • presenting overall performance on total expenditure and outcomes in a single, tabulated view; and • examining longer-term changes on key indicators since 2012-13. 2 Service delivery report 2018-19 Key messages Our analyses of companies’ relative performance in 2018-19 demonstrate that Anglian Water, Wessex Water and Portsmouth Water are the better performing companies within the sector. There are aspects of leading performance in most companies, as many companies rank in the top 25% in at least one key area. The delivery of services by Hafren Dyfrdwy and Thames Water is notably worse than the rest of the sector and requires improvement in multiple areas. In summary: The sector overspent against its total Twelve companies meet, or are on track Just over half of supply interruptions wholesale expenditure allowance by to meet, their leakage performance targets were achieved in 2018-19, despite 6% in 2018-19.

For total expenditure we use cumulative performance since 2015, given the movement of expenditure across years. For outcomes we examine performance in the most recent year, 2018-19. We also indicate the direction of change from 2017-18, for example whether outcomes performance has improved (p), for example a reduction in leakage between the years, an increase in the percentage of performance commitments achieved, or got worse (q), for example an increase in leakage or a reduction in the percentage of performance commitments achieved. We have grouped companies into three categories (better performers, average performers, and poorer performers) based on their in the round performance in relative assessments: • Anglian Water, Wessex Water and Portsmouth Water are better performers. These companies demonstrate top 25% or middle 50% performance across multiple areas. South West Water falls short on its performance on water quality contacts and significantly short on its performance on pollution incidents. As a result it sits between the better and average performer categories. • Thames Water and Hafren Dyfrdwy are poorer performers. The performance of these companies is in the bottom 25% in multiple areas. • The performance of the remaining companies is mixed and they are broadly in line with average performance of the sector overall. Most companies currently have broadly comparable performance commitments from PR14 with similar, but not identical definitions. To allow an indicative comparison between companies of different size we have normalised performance across the PR14 performance commitments, for example by kilometre of water main or sewer. For the next price control, we are introducing common performance commitments with consistent definitions for all companies. This will increase comparability. 4 Service delivery report 2018-19 Overall assessment of efficiency and effectiveness of service delivery Total expenditure Outcomes Top 25% Wholesale Retail Customer Meeting Earning Leakage Supply Water quality Internal Pollution Middle 50% service performance financial interruptions contacts sewer incidents commitments incentives flooding Bottom 25% Improved p performance Better performance Deteriorated q Anglian Water q q p q q q p p p performance Wessex Water q q q p p p q q Portsmouth Water q p p p q p p p - - Marginal performance – better/average South West Water q p p p p p p Average performance Dŵr Cymru q q p q p p p q Northumbrian Water q q q q p q q p Severn Trent Water1 2 Southern Water q p p p q q p p p q United Utilities p q p p p p p q Yorkshire Water q q p q p q q q Affinity Water q p p q q p p - - Bristol Water q q p q p p q - - South East Water q p q p p p p - - South Staffs Water q p p p p p q - - SES Water q q p q q q q - - Poorer performance Hafren Dyfrdwy1 -2 Thames Water q q q q q p q p p 1.
