Why inflation is falling but prices are still rising

The Office for National Statistics (ONS) which calculates inflation, bases its numbers on a basket of goods that reflects what most people across the UK are buying. But it doesn’t include everything. So if you are buying a lot of unusual or niche items, or you have atypical tastes, you might find the cost of your own bag of shopping is going up more quickly – or more slowly – than the headlines suggest.
