Nearly £150billion of house sales took place across the UK in the first 15 weeks of this year.
That represents almost double the value of homes sold subject to contract in the same period in 2020 and 2019, according to Zoopla.
The research also found that strong activity is reducing the supply of houses available. It said the total number of homes on the market and not yet under offer was around 30 per cent down in early April compared with average levels between 2017 and 2019.
Three and four bedroom houses have recorded the sharpest fall in supply.
