My Lords, the technical amendments in this instrument, which was laid before the House on 21 July, amend the Water Industry Act 1991 to reapply developer service duties to water and sewerage undertakers —generally known as water companies—operating in retail exit areas wholly or mainly in England.
As part of competition introduced into the water sector, a “retail exit area” is where a water company, such as Thames Water, has transferred its “retail”—business or non-household—customers, such as supermarkets, to a separate company or “retailer”. The retailer liaises with Thames Water for the water and sewerage services to be provided to the business customer and the retailer bills the business customer for the services and offers it advice on how to improve its use of water.
This market allows business customers to have all their water and sewerage services looked after by one retailer, saving them time and money in dealing with billing for these services. This was not possible when water companies dealt with business customers directly. The market also enables retailers to work directly with housing developers for their water and sewerage services, which they need when building new homes, as housing developers are of course also businesses.
To set up the developer services for retailers, we disapplied some water company duties through the Water and Sewerage Undertakers (Exit from Non-household Retail Market) Regulations 2016. These disapplications have had unintended consequences for developer services, which is why we are now seeking to reapply the duties and to set up developer services for retailers in a slightly different way. I should make it clear that all the amendments introduced by this instrument are therefore technical operability amendments and do not introduce any policy changes.
The Water Industry Act 1991 is the principal piece of legislation setting out the duties and functions of water companies in England and Wales. The retail market is a devolved matter and the 2016 regulations applied to English water companies only. The market opened in April 2017, but water companies did not all transfer business customers to retailers when the market opened. The last water company to transfer its business customers to a retailer was in 2019. The effects of the way in which the developer services market was set up were therefore not fully realised for a few years after market opening.
When setting up the market for developer services, Defra recognised that some developers might still wish to work with the water company for the housing developer services, for example. We envisaged that housing developers choosing this route would make their own contractual arrangements with the company. However, in subsequent discussions with Ofwat, the economic regulator of the water industry, and with the water industry itself, it emerged that contractual arrangements are not straightforward. They do not sufficiently replicate the water company duties within the 1991 Act that were disapplied and the unintended consequences include Ofwat no longer being able to determine complaints from a housing developer about the developer services provided, as well as water companies having restricted access to water and sewerage pipes to maintain them.
