The Bank of England's (BoE) monetary policy committee (MPC) expressed "uncertainties" over the durability of the U.K.'s economic recovery, minutes of its last meeting revealed on Wednesday.
The cautious tone of the minutes - which comes despite the BoE updating its growth, inflation and unemployment forecasts last week - could serve to damp expectations by some analysts of a rate hike in early 2015.
"There were uncertainties over the durability of the recovery and the extent to which supply growth would keep pace with demand. There were also risks surrounding wage and price-setting," the minutes said.
"With the proviso that medium-term inflation expectations remained sufficiently well-anchored, the projections for growth and inflation under constant Bank Rate underlined that there could be a case for not raising Bank Rate immediately when the 7 percent unemployment threshold was reached."

The bank has previously given guidance that it would not consider raising the main interest rate (Bank Rate) from its current 0.5 percent until the jobless rate falls to this level.
Melanie Baker, U.K. economist at Morgan Stanley, told CNBC that when the 7 percent jobless target is met the BoE could re-set its so-called "forward guidance", which appears to be successfully managing peoples' expectations.
"The MPC have made a fair point: if we weren't in an environment with this specific forward guidance... people would be thinking that rates could rise much sooner than they are at present, given the seer strength of some of the incoming data."
