What are codes for adoption?

The Water Act 2014 introduced changes to the Water Industry Act 1991 (WIA91) requiring Ofwat to issue statutory codes for adoption agreements. These are the agreements that developers or self-lay providers (SLPs) enter into when they want an appointed water or sewerage company to take over responsibility for infrastructure they have constructed. They are the agreements entered into under section 51A WIA91 for water infrastructure, and under section 104 WIA91 for sewerage infrastructure.

The water code documentation was approved by Ofwat in September 2020. The approved set of documents can be found here.


When do they come into force?

The new water codes for adoption went live in January 2021. To comply with these codes, water companies are required to publish a number of documents and procedures, all of which can be found below.
