Tap Water in London?
Borough-by-borough breakdown of London's water quality — what's in it, what's safe, and what to do about it.
Yes — London tap water is safe to drink. But "safe" ≠ "clean".
Thames Water treats London's tap water to meet strict UK Drinking Water Inspectorate (DWI) standards. You won't get sick from drinking it. However, London has some of the hardest water in the UK — with a TDS of ~320 ppm driven by its chalk and limestone geology. This means high calcium, magnesium, residual chlorine, and in older homes, traces of lead. Perfectly within legal limits. Not ideal to drink unfiltered.
