Nationwide said that house prices ticked up by a seasonally adjusted 0.6 percent on the month - the biggest rise since April 2010 - and were 0.9 percent higher than a year earlier.
That is follows a surprise monthly fall in January.
Economists polled by Reuters had expected prices to edge up by 0.2 per cent on the month and by 0.4 per cent on the year.
"It remains to be seen whether this trend will be sustained," said Nationwides's chief economist Robert Gardner.
He added that, given the "challenging" economic backdrop, the housing market may have been boosted temporarily by relief for first-time buyers from stamp duty tax charged on land
and property transactions, which expires in late March.
"If so, this may continue to support activity and prices in the near term before cooling over summer."
