There isn't a single fixed price for 1-bed flats in Kingston, but recent data gives a solid starting point. Independent portal GetAgent reports that one-bedroom properties across Kingston upon Thames are currently selling for an average of just over £365,000.
When you drill into live listings in KT1 and KT2 on portals like Zoopla, you'll see a cluster of well-presented 1-bed flats in the low-to-mid £300,000s, with higher figures for riverside and new-build schemes, and lower prices for ex-local authority or homes needing work.
A tailored valuation from a local agent will always take account of your exact address, lease terms, outlook and condition – factors that simple postcode averages can't see.
