"Given the lockdown started to be eased in May, April will mark the trough in GDP. So we are past the worst," Andrew Wishart, an economist with Capital Economics, said.
"While the trough inactivity is now behind us, the fiscal cost of the collapse and the rise in the unemployment rate to over 8% that will result are only just starting to emerge."
BoE Governor Andrew Bailey said on Wednesday he could see some signs of an economic recovery as the coronavirus lockdown restrictions were lifted, but he warned there was still likely to be long-term economic damage.
The BoE is expected to announce a further increase of at least 100 billion pounds in its bond-buying firepower next week to try to stop the coronavirus crisis from inflicting further damage on Britain's economy.
