Friday 16th December: Southern Water posted their ’Wave 3′ SIM scores late on Friday, which was the highest score that they have achieved since the scoring methodology was changed. Cappagh Browne contributed with a score of 4.38 out of 5, ranking us 5th out of 10 UK waste water companies in this wave. This was also our highest SIM score yet and Southern Water’s highest for waste since the SIM scoring methodology was changed. The SIM score is allocated by water regulator Ofwat after a series of our customers are contacted at random to rank their experience of our services out of 5.
