The average time it took a home to sell last year - measured from its first day listed on a portal until it was sold as marked by the Land Registry - was 256 days.
The figure has been produced by comparison website GetAgent which says that in London the average time was even longer - 195 days.
This average time increased throughout the year; it was 250 days during the first quarter of 2019, increasing to 271 days by the final quarter.
The pocket of the nation that endured the biggest market slowdown was Eden in Cumbria, where the average property sale took 393 days to complete; Westminster was home to the second-longest selling time (and the worst in London) taking 390 days to complete.
Ceredigion ranks as the slowest market in Wales with the average sale dragging out for 388 days, while homeowners in Islington (373), Camden (333), Copeland (332) and Richmond (331) also saw their sale take longer than 330 days.
Some areas defied wider market conditions to enjoy much shorter selling times.
The best in the nation was Nuneaton and Bedworth, where the average property took just 191 days from first listing online to completion. Torfaen was the best performing market in Wales with homes selling in 193 days on average, while Bromsgrove in the Midlands ranked third at 197 days.
Other areas to see the time to sell sit below 210 days include Trafford, Bolsover, North East Lincolnshire, Stockport, Walsall, Charnwood, Wellingborough, Mansfield, Redditch and Coventry.
In London, Bexley (230), Barking and Dagenham (235) and Newham (247) were home to the quickest home sales of 2019.
“It’s clear that the ongoing market uncertainty surrounding Brexit had a direct impact on selling times across the nation over 2019, increasing almost consistently throughout the year and culminating with the longest selling times seen all year, due to a combination of pre-election angst and a seasonal market slowdown in the final quarter of the year” explains GetAgent founder and chief executive, Colby Short.
“It’s now clear that December’s election result has spurred an almost immediate market revival and with high levels of activity returning on both the buyer and seller side of the fence, growing momentum should see the time taking to sell reduce substantially over the coming year.”
