Houses in Wallington cost about £415,000 at the middle of the market, and that middle is propped up by flats. A flat goes for about £280,000. A semi costs about £600,000. Detached houses barely come up, and when they do they cost close to £900,000. One town, three entirely different budgets.
The Land Registry recorded 282 sales in Wallington in the year to May 2026, at a median of about £415,000. Flats were the busiest part of the market, with 125 sales at a median of about £280,000. Terraced houses went for about £470,000 across 70 sales, and semis for about £601,000 across 69. Only 18 detached houses sold, at a median of about £892,500. Anyone holding out for a detached house here should expect to wait for somebody else's retirement.
The house price index for the area moved very little in the year to May 2026, rising about 0.9% to an average of around £445,000. Flats went the other way, down about 1.4% over the same twelve months. Over five years the index is up about 11%. So the flat owner hoping to trade up to a semi is selling into the soft end of the market and buying into the firm one.
Band C is the most common council-tax band in Wallington, and only about 13% of homes fall in bands A or B. The London Borough of Sutton's band D bill comes to about £2,379 a year, the figure most buyers can set against what they pay now. Budget for a bill a band or two either side, depending on the size of the house.
Renting is priced by the borough: across the London Borough of Sutton, typical private rent was about £1,550 a month in April 2026. That is a mean from the Office for National Statistics' rent index for the whole borough, so Wallington's own streets will land either side of it. By bedroom, a one-bed averaged about £1,230 a month, a two-bed about £1,545, a three-bed about £1,885 and four or more about £2,480. No reliable figure exists for studios or single rooms.
Median household income across Wallington was about £82,000 a year before tax, an Office for National Statistics model for the financial year to March 2023, so it describes incomes three years ago. Against a median price of £415,000, that puts a flat within reach of a household on the local median and a semi firmly in two-good-salaries territory. The mortgage broker works from the gross figure. The household lives on what is left after the tax.
Of the sales that could be matched to an energy certificate's floor area, about 64% of them, the median price came to about £5,400 per square metre, on a typical floor area of about 93 square metres. The Domesday Book measured Wallington in hides. The Land Registry prefers square metres, and charges accordingly in the modern way, one sale at a time. Ask for the floor area on any home you view; the price per square metre is only useful if the number you compare it to is real.
In the 2021 census, about 18% of Wallington's homes had one bedroom, 30% two, 31% three and 21% four or more. Two-bed and three-bed homes make up most of the town, so most buyers are choosing between them, and the cost of that one extra bedroom is where Wallington's prices start to bite.
On cost, Wallington is middling: flats are a fair price for this part of London, and the houses are priced for buyers who already have one to sell.
