Consulting on a price for Tata Steel's water supply from Dwr Cymru 

We have published our draft determination on the dispute between Tata Steel and Dwr Cymru over the terms and conditions for the supply of non-potable water to Tata’s site in Llanwern, Wales under the Water Industry Act 1991. The draft determination sets out a price that is based on Dwr Cymru’s costs to supply the Llanwern site. It also makes a provisional determination on several non-price terms of the agreement.
 


PR14 reconciliation rulebook  

Our reconciliation rulebook sets out our approach to the reconciliations that will be required at the end of the 2015-20 price control to take account of past performance and the various price control incentive mechanisms. We consider that setting out our approach now will provide greater clarity to customers, companies and wider stakeholders, and is consistent with building trust and confidence in the water sector.

TapReferral of Bristol’s final determination, and South West's acquisition of Bournemouth to CMA

In December we set limits on the prices companies can charge between 2015 and 2020. Our decision meant that average bills in England and Wales are due to fall by around five per cent in real terms by 2020, while at the same time seeing improved levels of service. All but one company accepted our final determination. Bristol Water asked for its final determination to be referred to the Competition and Markets Authority (CMA) for review. We have now done this. The process is now taken forward by the CMA who will open Bristol’s final determination. Updates on the case, including our opening statement, are available from the CMA.

In April 2015 Pennon Group plc, the parent company of South West Water, acquired Bournemouth Water. As the turnover of both water companies is above £10 million this merger was automatically referred for investigation by the Competitions and Markets Authority (CMA). The CMA must decide if the merger will prejudice our ability to make comparisons between water companies and if so, what action must be taken to remedy, mitigate or prevent the prejudice or any adverse effect. Updates on the case, including our submission, are available from the CMA.
