For 2 people, a useful 2026 planning range is £465–£650 a year. Our central estimate is £558, or £46.50 a month.
How we estimate it
We start with around 100 cubic metres of annual consumption, then apply a blended combined water and wastewater rate with typical fixed charges. Actual company tariffs have different unit prices and standing charges.
Every 10 m³ is 10,000 litres
A daily change of about 27 litres across the household adds up to roughly 10 m³ over a year.
How to lower the bill
- Check the meter when no taps or appliances are running to spot a possible leak.
- Use eco cycles and wait for full dishwasher and washing-machine loads.
- Reduce shower time by two minutes; hot-water savings can exceed the water saving.
- Ask the supplier about free water-saving devices and support tariffs.
Questions for a 2 people home
Is £558 the exact bill for 2 people?
No. It is a UK planning estimate for a metered household using about 100 cubic metres a year. Regional tariffs and actual habits can move the result considerably.
Would an unmetered bill be cheaper?
It depends on the property's rateable value. Household size does not change an unmetered charge directly, whereas every extra cubic metre affects a metered bill.
