The UK is on course to be a £2 trillion economy - the fifth largest in the world - by 2017, according to PwC's latest monthly global economy watch.
Its latest publication looks at the UK and global economies and makes predictions for 2015 and beyond.
PwC says UK economic growth was around 3 per cent in 2014, the fastest in the G7, but is projected to slow to around 2.5 per cent this year, behind the US and Canada, but the strongest of the large European economies.
Inflation should remain below its 2 per cent target rate, which should help to produce a return to positive average real wage growth.
Unemployment should continue to fall steadily through the year, potentially to pre-recessionary rates of around 5 per cent of the labour force, while house price inflation may moderate over the course of 2015.
