These companies are responsible for providing a continuous supply of clean water of adequate pressure to all customers in an agreed geographical area. Currently customers in the UK are unable to switch from one supplier to another, with water rates controlled by independent regulator Ofwat.

Similar to the electric and gas industry, water companies have come under close scrutiny from the British public, where a lack of competition, increasing water rates, record breaking fines for leakages and poor investment in modern complaints and customer service processes have added to a growing dissatisfaction and frustration amongst UK consumers. These same consumers are turning to social media channels to vent their frustrations and ask for help.

Last week the Consumer Council for Water published their annual report on Consumer Complaints. Despite water companies receiving over 2m+ contacts last year from customers, there was a clear trend towards an overall decline in the number of written complaints and unwanted telephone contacts being made to water companies over the last 7 years, since 2010.

The recent complaints report published by the Consumer Council for Water shows a direct correlation of the rise and impact of mobile messaging channels for customer service and digital communications.

Customer service on mobile messaging channels is more convenient for customers and cheaper and more efficient to support than legacy channels like phone, email and if I have to say it snail mail. ? ?

Written complaints fall by 11%

For the first time in more than 20 years, fewer than 100,000 written complaints were received by the water companies of England and Wales. In total, companies received 95,274 written complaints, an 11% fall on the previous year and a continuation of the downward trend seen since the peak year of 2007–08 when over 273,000 written complaints were made against water companies.

In a heavy regulated industry, change can be slow, and innovation can be even slower. But with consumers currently frustrated with existing legacy processes and the rise in the adoption of more convenient mobile messaging channels, water companies are now having to embrace the new world to improve the overall customer experience and bring customer service into the 21st century.
