New property listings rose 0.8 per cent in April, according to data collected by Housesimple.
The number of new listings to the market rose from 57,225 recorded in March, to 57,710 last month.
Meanwhile, new stock in London was down 1.4 per cent in the same time frame.
According to the report, 49 per cent of all towns and cities in the analysis recorded a rise month-on-month in new property listings.
The figures show that across the country, Stevenage saw the largest rise in April at 69.4 per cent. This was followed by Salford at 43.8 per cent, and Chichester at 33.8 per cent.
Within London, Kensington and Chelsea recorded the largest increase in the number of new property listings between March and April at 17.3 per cent. Followed by Islington at 12.4 per cent, and Sutton at 11.1 per cent.
Housesimple chief executive Sam Mitchell comments: “Homeowners wasted little time in marketing their properties once the new Brexit date was confirmed.
“There was inevitably a slight lull in market activity in early April, but activity has picked up noticeably since 12 April, and although we have seen a more subdued spring bounce than in previous years, under the circumstances, seller numbers are at healthy levels, particularly in the north.
“Looking ahead, uncertainty will persist until there is more clarity around our future relationship with the EU, and naturally this will play on sellers and buyers’ minds.”
