Planning designations from planning.data.gov.uk and Environment Agency flood-risk data, © Crown copyright and database right, under the Open Government Licence v3.0. Coverage is incomplete and depends on the local authority — absence here does not guarantee a property is unaffected. Always check official sources.
Averages cover every recorded sale in W1U 6NS (2015–2025) and are not adjusted for house-price changes over that period — where the market has risen, older sales pull the average below today’s values, so treat this as a rough guide rather than a like-for-like comparison.
This address covers more than one registered unit or interest (for example separate flats, or a leasehold and the freehold). The Property column shows each one. These are separate Land Registry entries, not repeat sales of one home.
