Tap water in United Kingdom

Generally safe to drink

The WHO and UNICEF put safely managed drinking water within reach of 100% of people in United Kingdom. National figures describe a country, not the tap in front of you.

What the sources say

Lonely Planet

The tap water is safe to drink.

Safe nationally still means ask locally. Older buildings can carry lead or copper pipework, and a single street can differ from the network feeding it. If you are staying somewhere old, ask your host.

What bottled water costs you here

Drinking tap water instead of bottled would save one adult about 876$ a year in United Kingdom, and keep several hundred plastic bottles out of circulation.
