Markit Economics and financial information provider Ipsos Mori released its household finance index (HFI) for the U.K. on Wednesday. The household finance index increased to 45.3 in April from 44.8 in March.

The index measuring the outlook for financial well-being over the coming twelve months decreased to 49.6 in April from 51.4 in March.

The current inflation perceptions index climbed to 66.8 in April.

The index measuring expected living costs over the twelve months was up to 81.6 in April.

One-quarter of respondents expects the Bank of England's monetary policy to tighten within the next six months.

"Latest HFI data from Markit paints a mixed picture for UK households. On the one hand, the squeeze on finances softened in April… In contrast, the financial outlook worsened for the first time in three months," economist at Markit, Philip Leake, said.
