WF postcode district map, Wakefield

Where the WF districts sit

Where WF sits

It is administratively fragmented, reaching into Wakefield, Kirklees, Leeds and North Yorkshire and 0 other authorities.

Water supply across WF

All 18 WF districts are supplied by Yorkshire Water. That makes WF simple in a way many areas are not: one company, one set of rules, one status to check.

No hosepipe ban currently applies anywhere in WF.

The shape of the WF area

The districts are wildly uneven: WF2 holds 1,330 postcodes around Wakefield and WF90 holds 3, a ratio of about 443 to one. They divide into 75 sectors.

The numbering is not continuous. WF runs up to 90 but has only 18 districts, so 72 numbers are unused:.

Several districts share a settlement, which is a common source of confusion when a form rejects an address: WF1, WF2 and WF90 all point at Wakefield and WF12 and WF13 all point at Dewsbury.

What borders WF

WF sits next to LS (Leeds) to the north, HD (Huddersfield) to the west, HX (Halifax) to the west, S (Sheffield) to the south and BD (Bradford) to the north west.

Its neighbours run in 4 different directions, so WF is landlocked by other postcode areas on most sides.

WF districts, settlements and water supply

Principal settlement is the town or city each district sits in or nearest to, derived from OS Open Names. It is not the Royal Mail post town, which is licensed data and not published openly. Status is resolved live from each company’s own notice.

Water hardness in WF

Figures are in milligrams per litre as calcium carbonate, the unit UK water companies report in. 18 of 18 districts have a published figure.

Descriptions such as very soft, soft, moderately hard, hard, very hard are the water industry scale: very soft below 75, soft 75–125, moderately hard 125–250, hard 250–375, very hard above 375 mg/l. Your supplier may use a different scale for the same number.

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.
