The economy grew at its best annual pace on record in 2021 despite a December hit from measures to control the spread of the Omicron COVID variant, early official estimates have revealed.

Data from the Office for National Statistics (ONS) showed the pace of growth between October and December – the fourth quarter – was largely static on the previous three months at 1%.

That was despite gross domestic product (GDP) contracting by 0.2% – slightly better than economists had expected – during December compared to the prior month.

Consumers were already found to have brought forward purchases for Christmas to October and November in anticipation of supply chain disruption and tighter COVID rules, including guidance to work from home, that were introduced to protect the NHS amid record case numbers.

It meant, the ONS said, that the economy grew by 7.5% over the course of 2021.

All its figures are subject to future revision but it followed the deepest slump for 99 years in 2020 when the pandemic first took hold, plunging large parts of the economy into hibernation as lockdowns were introduced for the first time.

The government’s hope, looking ahead, is to live with COVID without the need for tough curbs on activity.
