Referral of South West's acquisition of Bournemouth to 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.

TapReferral of Bristol’s final determination 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.
