Contains Yorkshire Water drinking water quality data, via Stream, licensed under CC BY 4.0. Edition 2026, published 1 January 2026. Yorkshire Water publishes this as mg/l without naming the species. We read it as calcium carbonate because the determinand is Hardness total and the dataset contains no calcium determinand. Evidence: determinand "Hardness total"; DWI code "HARD T"; no calcium determinand published in the dataset.
Hardness is published per census area, not per postcode, so these figures characterise a district rather than measuring one address. They are a scale and taste matter, not a safety one. Hardness data version wessex-water@2022-2025+yorkshire-water@2026.

Frequently asked questions
How many postcode districts are in the HX area?
There are 7 HX postcode districts, running from HX1 to HX7, and they contain 5,715 live postcodes across 31 sectors.
What towns does the HX postcode area cover?
HX covers Halifax, Sowerby Bridge, Elland and Hebden Bridge. The area takes its name from Halifax, and each district is listed with its settlement in the table on this page.
Which water company supplies HX postcodes?
Yorkshire Water supplies all 7 HX districts. Supply boundaries follow the pipe network rather than postcode geography, so confirm against your water bill if you are near the edge of the area.
Why do HX1 and HX2 both say Halifax?
HX1, HX2 and HX3 all serve Halifax, covering different parts of it. A single town routinely needs more than one postcode district once it passes a few thousand delivery points, so this is normal rather than an error in an address.
Can I download a free HX postcode map?
Yes. This page offers the HX districts as GeoJSON, CSV and SVG, free and with no signup or email address required. The GeoJSON carries each district's position, its water company and its current restriction status, so it can be dropped straight into a mapping tool.
Which councils cover the HX postcode area?
HX reaches into Calderdale and Kirklees. A postcode area is not a council area: they were drawn for different purposes and a single district can sit across a council boundary, so your postcode does not tell you which authority you pay.
How many postcode sectors are in HX?
HX contains 31 postcode sectors across its 7 districts. A sector is the district plus the first digit of the second half of the postcode, and it is the level a delivery round is actually planned around.
