Real estate agent Foxtons reported falling sales on Thursday, as Britons held off on home purchases.
The U.K. real estate company posted a 3.1 percent decline in revenue in the first three months of the year to £33.1 million ($51.1 million).
"Property sales transactions in London have remained relatively flat since the end of last year, with many potential buyers and sellers apparently delaying their decisions until the outcome of the General Election is known," said Foxtons CEO Nic Budden in a trading update on Thursday.
Nationwide, which publishes a widely watched monthly housing index, said earlier this week that activity in the market remained "fairly subdued," with mortgage approvals still "well below" the long-run average and 20 percent below the levels recorded in early 2014.
"The strength of the economy and relatively subdued pace of activity in the housing market remains something of an anomaly. It is possible that heightened uncertainty ahead of the election is weighing on activity, though there is no compelling evidence from previous U.K. elections to suggest a strong impact," Nationwide Chief Economist, Robert Gardner said, in a research note on Wednesday.
It comes as the U.K. Land Registry reported on Thursday that house prices in England and Wales fell 0.8 percent in March. This took the average property value to £178,007($274,309), down from a peak of £181,049 in 2007.
