The jobless total dipped by 79,000 to 1.77 million people between June and August, the Office for National Statistics said in a statement. That was the lowest level since the summer of 2008.
The unemployment rate -- the proportion of the labour force without work -- also sank to a seven-year low at 5.4 percent. That compared with 5.5 percent in the three months to July.
Employment meanwhile rose 140,000 to 31 million people, the highest since records began in 1971.
So far this year, inflation has languished close to zero on the back of a fierce supermarket price war, while slumping global oil prices have dragged fuel costs lower.
"Wages continue to grow strongly in real terms," said ONS labour market statistician Nick Palmer.
On a downbeat note, the number of people claiming jobless benefits increased in September by 4,600 to 796,200.
