LONDON (Reuters) - The number of British people leaving their homes to go shopping has slumped by 83% since the government closed non-essential retail outlets last month to slow the spread of COVID-19, the British Retail Consortium trade body said on Monday.
Separately, property website Rightmove said it was unable to provide meaningful house price data due to a collapse in the number of new homes being listed for sale.
Last week the BRC said retail spending had fallen by more than a quarter in the same period compared with a year ago, and Monday's figures show the decline in the number of people going out has been even sharper.
"Footfall dropped in early March, as many people chose to stay at home and reduce the risk of catching coronavirus," BRC chief executive Helen Dickinson said.
"This downwards trajectory was accelerated by the government's decision to put the UK on lockdown."
Last week Britain's budget forecasters said the economy could shrink by an unprecedented 35% in the second quarter of 2020 if it was on lockdown for the next three months.
Supermarkets and other retailers of food and essential goods are still open, and the BRC said convenience stores had recorded increased traffic since the lockdown started on March 23.
Rightmove - which typically advertises more than 90% of houses for sale on behalf of British estate agents - said there had been an "abrupt turnaround" from the best start to a year since 2016 to new sales now being almost impossible.
"You do not have a functioning market when buyers can't buy and sellers can't sell, and so the focus needs to be on what is required to help the market recover once the lockdown can safely be eased," the company said.
Visits to Rightmove's website fell by around 40% at the time of the lockdown announcement but had started to recover slowly over the past week, it said.
For the "daily dwindling number" of properties put up for sale between March 8, before the lockdown began, and April 11, average asking prices were 2.1% higher than the same period in 2019, it added.
Britain's Royal Institution of Chartered Surveyors warned on April 9 that the property market was coming to a "near stand still" and it predicted a record drop in sales.
