Howard Archer of IHS Global Insight said: "The MPC is not taking sustained recovery for granted and very much wants to see it become more balanced with business investment seeing sustained improvement and exports increasingly kicking in.
"There are some signs that the UK economy may recently have lost a little momentum, although it still appears to be growing at a healthy clip."
Last week, Bank governor Mark Carney refused to rule out a pre-election rise in interest rates, but stressed that any rise would be gradual.
He added that despite unemployment falling more quickly than expected, there remained "slack" in the labour market "right across the country", more of which needed to be used up before any hike.
Mr Carney told a newspaper the recovery in the economy had been "uneven" and needed to be seen across the country.
Martin Weale, a fellow member of the MPC, has previously indicated that a rise in the cost of borrowing was likely next spring, and appeared to suggest it would come before the May general election.
