In a statement today, the bank said it had lifted its benchmark rate, which affects the cost of loans and savings rates in the wider economy, to 0.50 per cent from the record low of 0.25 per cent.
The hike, which had been widely anticipated in financial markets, is the first since July 2007, when world credit markets started to freeze up in what would prove to be the prelude to the global financial crisis.
Minutes of the meeting showed that seven members of the nine-strong Monetary Policy Committee judged it "appropriate to tighten modestly the stance of monetary policy" to return inflation to target.
Inflation, according to the central bank's quarterly projections, should fall towards target, to 2.1 per cent, in three years if interest rates rise in the way markets expect, to 1 per cent over that period.

In spite of that backdrop, rate-setters were faced with a dilemma as the British economy has come off the boil. It is the slowest-growing among its peers in the Group of Seven industrialized democracies and businesses and households are becoming more cautious amid uncertainty over Britain's future relations with the other 27 EU nations.
"The cautious comments in the accompanying statement have led many to believe that this is a case of one-and-done rather than the start of a sustained hiking cycle," said David Cheetham, chief market analyst at XTB.
All that could change, Carney indicated, if Britain is quick in getting a Brexit deal with the remaining 27 EU nations. Though Britain is officially due to leave the EU in March 2019, there is mounting pressure on the government to provide businesses with some clarity on the future following Brexit day. Many financial firms, for example, have threatened to start implementing contingency plans to set up operations in Europe or move staff and activities in the early months of next year if there is no progress in the Brexit talks.
Brexit, he added, is the "biggest determinant" of the British economy's outlook.
Inflation has been boosted in the past year by the pound's 15 per cent fall since the Brexit vote in June last year, which raised the cost of imported goods like food and energy. That impact is a one-off, the bank conceded, and is likely to fade in coming months while higher wages and productivity grow.
Though the rate rise may not amount to much, it has symbolic value.
"For a whole generation of U.K. households now entering adulthood, it's a small but important reminder that interest rates can move in an upward direction, even if only slowly," said Lucy O'Carroll, chief economist at Aberdeen Standard Investments.
Carney said he expected banks to follow suit, noting that they passed on last year's rate cut.
