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 TS area?
There are 29 TS postcode districts, running from TS1 to TS29, and they contain 17,884 live postcodes across 100 sectors.
What towns does the TS postcode area cover?
TS covers Middlesbrough, Stockton-on-Tees, Hartlepool, Thornaby-on-Tees, Billingham and Redcar. The area takes its name from Middlesbrough, and each district is listed with its settlement in the table on this page.
Why do neighbours in TS have different hosepipe rules?
Because 2 different water companies supply TS: Northumbrian Water and Hartlepool Water. A hosepipe ban is declared by a company for its own customers, not by council or by postcode, so two houses on the same street with different suppliers can be under different rules on the same day. The supplier named on your water bill is the one whose rules apply to you.
Why do TS1 and TS2 both say Middlesbrough?
TS1, TS2, TS3, TS4, TS6 and TS7 all serve Middlesbrough, 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 TS postcode map?
Yes. This page offers the TS 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.
Why is the TS area called Middlesbrough when it covers Redcar?
TS takes its letters from Middlesbrough, where the sorting office that served the area was based when the code was allocated. Redcar is the largest settlement in the area today, in TS10, but the area code follows the historic sorting geography rather than current population.
Which councils cover the TS postcode area?
TS reaches into Stockton-on-Tees, Redcar and Cleveland, Middlesbrough, Hartlepool, North Yorkshire, County Durham and Darlington. 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.
