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 FY area?
There are 8 FY postcode districts, running from FY1 to FY8, and they contain 7,390 live postcodes across 40 sectors.
What towns does the FY postcode area cover?
FY covers Blackpool, Lytham St Anne's, Thornton, Poulton-le-Fylde and Fleetwood. The area takes its name from Blackpool, and each district is listed with its settlement in the table on this page.
Which water company supplies FY postcodes?
United Utilities supplies all 8 FY 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 FY1 and FY2 both say Blackpool?
FY1, FY2, FY3 and FY4 all serve Blackpool, 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 FY postcode map?
Yes. This page offers the FY 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 FY area called Blackpool when it covers Lytham St Anne's?
FY takes its letters from Blackpool, where the sorting office that served the area was based when the code was allocated. Lytham St Anne's is the largest settlement in the area today, in FY8, but the area code follows the historic sorting geography rather than current population.
Which councils cover the FY postcode area?
FY reaches into Lancashire and Blackpool. 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.
