Mortgage approvals in the UK have risen, with some reports indicating a 4-month high and others suggesting a higher peak of 15- or 17-month highs. The increase in approvals was accompanied by varying reports on net mortgage borrowing, with some sources citing a figure of £4.4 billion in April, while others referenced a higher amount of £4.8 billion, although the latter may pertain to a different month. The Bank of England data appears to show an overall upward trend in mortgage activity.
