W1S Postcode: Mayfair & West End Guide with Map Pin

W1S postcode area and local context

The W1S outward code covers Mayfair retail core, St James’s edges, and premium West End offices, within the City of Westminster. People search for “w1s postcode” when they are buying, letting, or refinancing, because lenders, insurers, and conveyancers all rely on the same address string you see on Land Registry titles and council tax records.

Royal Mail assigns inward codes within W1S to narrow delivery points. For property analytics, Postcode Insights uses the full postcode to anchor maps, sold prices, and neighbourhood statistics—so capturing the complete code matters more than the outward half alone.

Research W1S with Postcode Insights

Start with your full postcode in our tools: nearest stations, crime context, EPC and sold prices where data exists. Headleases and event licensing can dominate investment cases—pair analytics with specialist valuation advice.

Benchmark against W1K and SW1Y when you judge pricing for lateral flats versus mansion blocks. You can jump straight from a map search to a full report when you need a single PDF-style summary for an offer or portfolio screen.

Stations, commutes, and comparables

Commute behaviour often dominates search intent around W1S. Use the nearest stations tool with a representative postcode, then compare travel times to work or school against neighbouring districts. Combine that with HM Land Registry sold prices to sense whether similar homes transact higher or lower just across a ward boundary.

Crime and safety statistics are published at granular levels that do not always match postcodes exactly; treat them as directional context alongside street-level viewing and local knowledge.

UK postcode format reminder

If you need to split outward and inward codes correctly—useful when filling forms or APIs—read our UK postcode format guide on this site. It explains why codes such as W1S follow the national pattern even when the letters look unfamiliar.
