The first thing you should do in order to cut your water costs is see if you can get a meter fitted. If there are less than three or four of your in a home, then the odds are you’ll benefit from the change. Water companies fit them for free, and if you don’t like it you can switch back in 12 months. If a meter cannot be fitted, then water companies often offer an alternative unmeasured tariff – which is usually less than the current bill.
Some other simple, practical steps can be taken. Try stopping dripping taps by replacing worn washers. Install a water efficient shower head and take showers instead of baths. Collect rainwater to use for your garden instead of hosing.
A quarter of all household bills come from heating water – in baths or showers, or for washing clothes and dishes. So if you can manage to keep it down, then you’ll be making a significant saving.
