Official figures show that cheaper footwear and clothing, with an increase in petrol prices, helped preserve the 0% rate.
The figure matched the lowest inflation rate of the Consumer Prices Index (CPI) since the records began in the 1980s.
This cost of living in the UK has remained the same as the year before.
But the ONS stated the inflation rate was calculated by two decimal places – so prices were -0.01% lower than last year. This was the first fall recorded by the CPI.
One of the key reasons that the CPI rate hardly changed was due to the rising diesel and petrol prices.
However the ONS added that the overall decrease in diesel and petrol prices over the last year contributed to the low inflation.
The figure documented by the CPI leaves the inflation rate well below the Bank of England’s target of 2%.
There was speculation that the CPI rate could have fallen below 0% in March, and it’s still possible that it could do so in the coming months.
However there are a small number of economists who think the UK is at risk of deflation, similar to what Japan has suffered.
The director of economics at the CBI business group, Rain Newton-Smith said:
“Inflation should start to pick up in the second half of the year, especially as the downward pressure from lower oil prices eases.”
