Kingston costs about £545,000, and that mostly buys a flat. Flats go for around £410,000. A semi runs to about £750,000. Prices barely moved over the year. Kingston has stopped getting dearer without getting any cheaper.
The Land Registry recorded 204 sales in Kingston in the year to May 2026, at a median of £545,000. Flats made up the biggest share, 95 sales at a median of about £410,000. Semi-detached houses followed with 65 sales at about £750,000, and 36 terraced houses sold at about £551,000. Only 8 detached houses changed hands, at a median of about £1,288,000. Eight sales in a year is less a market than a rumour, and one unusually grand riverside house would move that median on its own.
The official house price index for Kingston upon Thames put the average at about £582,000 in May 2026, with no change at all over twelve months. Flats did slightly worse, down about 2% on the year to an average of about £361,000. Over five years the index is up about 10%. A buyer hoping for a bargain will find a market that has paused, which is a different thing from one that has dropped.
Band D is the most common council-tax band here, and only 11% of homes fall in bands A or B, the cheapest two. The Royal Borough of Kingston upon Thames charges about £2,610 a year for a Band D home, which is the number to hold against your current bill.
Renting across the Kingston upon Thames borough came to about £1,800 a month as of April 2026, up about 3% on the year, by the Office for National Statistics' rental index. That is a mean across the whole borough, so it folds town-centre flats in with family houses further out. By size, the borough averages about £1,370 for one bedroom, £1,740 for two, £2,140 for three and £2,820 for four or more. Studio and room rents are not published, so any figure quoted for them comes from a listing, not the index.
Local households are well paid on paper. The Office for National Statistics models gross household income in Kingston at about £93,000 a year before tax, for the financial year to March 2023, averaged across the area; after tax that figure is about £59,000. Against a median sale price of £545,000, even that income makes a house a stretch, and a flat the realistic first rung. The gross number is the one that gets quoted at parties, and the net one is the one that meets the mortgage.
Of the sales that could be matched to an energy certificate's floor area, about 67% of the total, the median price works out at about £7,250 per square metre, on a typical floor area of about 88 square metres. That is what Kingston charges for space, and it charges flat buyers the same rate as everyone else for the privilege of a smaller box. With flats doing most of the selling, ask for the remaining lease length and the service charge history on any flat early, since both change what that per-metre price is really worth.
The 2021 Census found 22% of Kingston's homes had one bedroom, 33% two, 25% three and 20% four or more. Two bedrooms is the size the town is built around, which is why the 88-square-metre median sits where it does. Families wanting a fourth bedroom are shopping in the smallest fifth of the stock, against everyone else who wants the same thing.
Kingston is middling on cost: neither a bargain nor a runaway, just expensive in the steady way London towns near a river tend to be. The money goes furthest on a two-bedroom flat and shortest on anything with a garden of its own.
