A Reuters poll of economists had pointed to approvals of 49,000, after 51,143 mortgages were approved in May.
The value of net mortgage lending for the second quarter as a whole fell compared with the first quarter - the first quarterly contraction since records began in 1987.
The BoE is expected to raise interest rates to 5.25% on Thursday from 5.0%, which would be the highest Bank Rate since 2008.
"Looking ahead, growth in households' real disposable incomes will be weighed down by mortgage refinancing," said Samuel Tombs, chief UK economist at consultancy Pantheon Macroeconomics.
The BoE reported a 1.661 billion pound ($2.13 billion) monthly increase in net consumer lending June, the largest such increase since April 2018.
