Outcode NR24 Household Water Quality Verdict & Practical Advice
Domestic tap water in outcode NR24 is officially classified as very hard water, averaging 310 PPM (mg/L CaCO₃) or 21.7° Clark, supplied and treated by Anglian Water across all 1 postcode sectors (210 postcodes). Readings range from 310 PPM (NR24 2) to 310 PPM (NR24 2) with consistent mineral levels throughout.
☕ Kettle & Tea Quality:
Rapid limescale buildup in kettles with floating scum on your cuppa. Descale monthly using white vinegar or food-grade citric acid.
🚿 Skin & Bathing:
High calcium levels can aggravate dry skin & eczema sensitivity. Soap lathers less easily, often leaving a tight feeling after hot showers.
🍽️ Appliances & Salt:
Keep water softener salt topped up and calibrate dishwashers to H06 – H07 (Max salt). Protect combi boiler heat exchangers under BS 7593.

vs. UK Benchmark+55% Hardervs 200 PPM national average
Tired of stubborn limescale buildup in your kettle or dealing with an unappetising film of scum on your morning cuppa? Tap water across all 1 postcode sectors in outcode NR24 (covering 210 homes) averages 310 PPM (21.7° Clark). Maintained and distributed by Anglian Water, this places the district firmly into the very hard water bracket—approximately 55% harder than the UK national baseline (200 PPM).
Water hardness is remarkably consistent across all 1 sectors of NR24, with readings holding steady at 310 PPM from NR24 2 through to NR24 2. This uniform profile means every household on the Anglian Water network in this zone shares the same appliance settings and kettle descaling routine.
The reason tap water in NR24 carries significant dissolved minerals lies in local geology. Anglian Water abstracts substantial water supplies from subterranean chalk and limestone aquifers. As rainwater percolates through deep calcium-rich rock strata over decades, it dissolves natural calcium carbonate. While entirely safe and wholesome under Drinking Water Inspectorate (DWI) standards, these minerals precipitate out when heated above 60°C, leaving stubborn limescale deposits on heating coils.
Hard water in NR24 (310 PPM) often causes a cloudy scum on hot drinks and makes soap harder to lather, aggravating dry skin and eczema sensitivity after hot baths. For appliances, ensure regular water softener salt top-ups and calibrate your dishwasher to H06 – H07 (Max salt) to avoid cloudy glassware, white streaks, and heating element burnout across all 210 postcodes.
