Frequently Asked Questions

How much water does a shower use in the UK?

It depends on the shower type. An electric shower uses around 6 litres per minute — so an 8-minute shower uses about 48 litres. A mixer shower uses 10–12 litres per minute (80–96 litres for 8 minutes). A power shower uses 13–15 litres per minute, meaning an 8-minute power shower can use more than a full bath. Fitting a low-flow shower head can roughly halve the flow rate of a mixer or power shower.

How much water does a washing machine use per cycle?

A modern front-loading machine uses around 50 litres per cycle on a standard 40°C wash. Older top-loading machines can use 70–100 litres. Running a half-load or eco cycle on a modern machine typically reduces this to 30–40 litres.

Is a dishwasher more efficient than washing up by hand?

Yes — a modern dishwasher uses around 12–15 litres per cycle. Hand-washing the same load under a running tap typically uses 30–60 litres. For dishwashers to be more efficient, they need to be fully loaded and run on an eco setting where possible.

How much water does flushing the toilet use?

A modern dual-flush toilet uses 4–6 litres per full flush and 3–4 litres for a half flush. Older single-flush toilets use around 13 litres per flush. If your household flushes 5 times per person per day, switching from an old single-flush toilet to a dual-flush model can save over 25,000 litres per person per year.

How much does a running tap waste?

A running tap uses around 6 litres per minute. Leaving it running while brushing your teeth for two minutes wastes around 12 litres each time. A dripping tap can waste over 5,500 litres per year — equivalent to about 70 full baths.
