Is Tap Water Bad for You? The Truth About UK & London Tap Water Safety (2025 Guide)
Last updated: October 2025

Introduction: Why Tap Water Safety Matters More Than Ever
Clean, safe drinking water is essential for health and well-being. Yet growing concern about PFAS chemicals, bacteria, and microplastics has left many asking: is tap water bad for you?
In the UK, tap water is heavily regulated, but “safe” does not always mean pure. Understanding what’s in your water—and how to remove it—is key.
Discover the Bluewater Kitchen Station, an advanced home filtration system that delivers pure, mineralized water straight from your tap.
What’s Actually in Tap Water?
Tap water undergoes multiple purification stages, yet trace substances can remain:
- PFAS (“forever chemicals”)
- Chlorine
- Lead and copper from pipes
- Microplastics
- Residual bacteria

PFAS in UK Tap Water: The Hidden Chemical Threat
PFAS are synthetic compounds used in non-stick cookware and packaging. They persist in the environment and can accumulate in the human body.
Health Risks of PFAS Exposure
- Thyroid disruption
- Immune suppression
- Developmental issues
- Increased cancer risk
(EPA – PFAS Information), (EFSA – PFAS Safety)
Bluewater’s Kitchen Station with SuperiorOsmosis™ removes up to 99.7 % of PFAS and other pollutants.
Microplastics and Tap Water
Tiny plastic fragments can carry chemical residues and enter the human body through water.
Reverse osmosis and activated carbon filters effectively eliminate these particles.

Tap Water Bacteria: What You Should Know
Even disinfected water can collect bacteria like E. coli or Legionella inside home plumbing.
Boiling kills bacteria but not chemicals. For lasting purity, install a home water filter system.
Is Tap Water Safe to Drink in London and the UK?
Yes—UK tap water meets world-class standards, but London’s hard water can taste chalky and leave limescale.
