Customer Charter and Service Standards

Our vision is that 'customers always value the quality of our drinking water and the safe return of our wastewater to the environment'.

Our Customer Charter and Service Standards outline the level of service our customers can expect from us and, in addition, also highlight how our customers can help us to help them.

Service Standards

Contact and Appointments

  • We will aim to answer your telephone call within six rings.
  • We will endeavour to provide an initial response to all queries and complaints within five working days.
  • We will aim to give you 24 hours' notice if we need to change the time of an appointment.
  • We will always try to arrive at an appointment on time or within 30 minutes of the stated time if we have made a slightly more flexible arrangement with you.

Water Supply

  • We will aim to give you 24 hours' notice in writing if we plan to turn off your water in order to carry out scheduled maintenance.
  • If we need to turn your supply off in an emergency we will endeavour to advise you verbally beforehand or have someone on site who can assist you. 
  • When requested, we will always provide drinking water for any customers that are left without tap water as the result of a main's burst and will aim to restore supply to our customers within 12 hours.
  • We will aim to fix a leak from our water main, which is not affecting supply to customers, within 10 days.
  • Water meters will be installed free of charge. We will endeavour to complete the work within three weeks of request unless the location is problematic or dangerous, in which case it may take a little longer.

Flow and Pressure

  • As a general rule, with the tap full on, it should be possible to fill a one gallon (4.5 litre) bucket in 30 seconds.
  • If you believe that your water pressure is inadequate we will test it for you at Guernsey Water's controlling chamber where the pressure should not fall below 1.0 bar.

Drinking Water Quality

  • Our water will be safe and good to drink.
  • We will investigate any concerns that you have regarding water quality and take a sample of the water in your home for testing if necessary.
  • Guernsey Water monitors its treated water on a daily basis for bacteriological and chemical quality in line with the UK Drinking Water Regulations. The tests, which cover a range of around 130 different parameters, will be undertaken at three different stages in the water treatment process, namely at the water treatment works, at service reservoirs and at customers' taps.
  • We will publish our water quality results on an annual basis.


  • We will work with our customers to reduce the risk of foul water and surface water flooding from the public sewers. When flooding does unfortunately occur, we'll try to assist with alleviating the impact of that flooding. We'll also do our best to find out why it happened and look for solutions to help prevent it from happening again.
  • We will always investigate any public sewer issues that are reported to us by private drainage contractors or customers.
  • Food waste and non-flushables (such as baby wipes) should not be disposed of down your sink or toilet therefore we will endeavour to inform and educate as much as possible on this very important issue.
