How hard is the water in London?

If it comes back over 120 PPM, see our water softener guidance in the purification calculator.
Do I need a water filter in London?
With 1 health-based violation on record in 2021–2026, a certified filter is reasonable insurance here: reverse osmosis ($150–$1,300 installed, Angi 2026) covers lead, nitrates and PFAS at the tap. Test first ($50–$200) so you buy for what's actually present.
