Official data showed economic output expanded by 0.2% in August from July, matching the median forecast in a Reuters poll of economists.
"The UK economy is holding up but remains in a precarious state," said David Bharier, head of research at the British Chambers of Commerce.
The data showed Britain's huge services sector grew by a slightly stronger than expected 0.4% in August from July while manufacturing and construction shrank by 0.8% and 0.5%.
Investors are putting a chance of less than one in four on the BoE resuming its rate hikes after its next scheduled meeting in November.
Britain's economy stood 2.1% bigger than in February 2020, just before the coronavirus pandemic hit, the ONS said.
