The ONS said service sector output increased by 0.8% in January on a year earlier and was up 0.3% month-on-month, despite the snow impact at the start of the year.
It is hoped that this solid performance will offset woes in the construction and manufacturing sectors.
Increased demand for exports has been helping, boosted by the recent weakness of the pound, which makes it cheaper to buy British goods and services.
The BCC's survey showed improvements in both the manufacturing and services sectors, although employment had weakened.
David Kern, British Chambers of Commerce chief economist, said the results suggested the economy continued to grow in the first three months of 2013.

Britain will avoid a triple dip recession thanks to near record levels of exports from the powerhouse services sector, a business group said today.
The latest economic survey from the British Chambers of Commerce (BCC) revealed export deliveries and orders from the services sector - which accounts for more than three quarters of UK economic output - rose close to the all-time highs seen in 1994 during the first three months of 2013.
Its survey of more than 7,000 firms also found that business confidence had grown, while firms were looking to invest more in their businesses.
