What you can do?
It is important that your hot water system is kept hot, your cold water is kept cold and the water in general is kept circulated by regular use. If you go on holiday and leave your property vacant for a few days or more, ensure on your return that your taps and showers (not forgetting any outside taps) are flushed by running them for at least 2 minutes.
It is equally as important that you tell us if your boiler is not working properly, particularly if you notice any debris or discolouration in the water coming from your taps. We ask that you do not interfere with the settings on your boiler or hot water system. Following your annual heating service, the hot water will be set so that the water is heated up to 60°C. This is the temperature to which legionella bacteria cannot grow.
