The firm analysed sold price records from the Land Registry over the last 12 months and found that a total of 12,251 homes have sold for £1m or more in that time; doing so with an average price tag of £1,333,286.
London remains the most prominent £1m plus property market accounting for a huge 58% of all transactions above the £1m threshold in the last 12 months.
At 23% the South East also accounted for more £1m+ property sales over the last year than all the other regions combined.
Wales and the North East were home to just 0.2% of homes to sell for £1m or more in the last year; the lowest of all regions in England and Wales.
Interestingly, while the Yorkshire and Humber region accounted for just 1% of all transactions above £1m, it was home to the highest average sold price at £1.544m. At £1.5m, the North West also saw one of the highest average sold prices for homes selling at £1m or more.
16 of the top 20 local authorities to have seen the most £1m+ property transactions in the last 12 months are located in the capital.
Westminster has seen the highest level of homes sold for £1m or more of all local authorities in England and Wales. 876 £1m+ transactions completed in the borough over the last year, with Kensington and Chelsea not far behind with 753 transactions. Wandsworth (708), Hammersmith and Fulham (530) and Camden (502) also saw some of the largest numbers of homes sold at £1m or more.
Elmbridge has seen the 9th most £1m+ homes sold in the last 12 months and the highest total outside of London with 327 transactions.
Windsor and Maidenhead (145), Waverley (143) and St Albans (137) also make the top 20, as do the London Boroughs of Richmond, Lambeth, Barnet, Islington, Southwark, Haringey, Ealing, Merton, Brent and Bromley.
Ben Taylor, CEO of Keller Williams UK, commented: “The higher tiers of the housing market have arguably suffered most due to Covid uncertainty and activity hasn’t been boosted to the same extent as a result of the current stamp duty holiday.
"That said, it’s reassuring to see that a robust number of transactions have still taken place despite the turbulence of the last year and this is a foundation that will no doubt be built on in 2021.
"Of course, London leads the way in terms of the sheer volume of sales but there has been activity across all regions of England and Wales and, in fact, some regions have seen these transactions complete for a similar or even higher average sold price than the capital itself."
