UK consumer confidence has dropped for the third quarter in a row with a three percentage point fall in the three months to June.

This represents the biggest quarterly decline in more than two years, according to the latest Consumer Tracker report from Deloitte.

The quarterly survey of 3,000 UK consumers saw overall consumer confidence fall to minus 10%, down from  minus 7% the previous quarter.

Spending across both essential and discretionary categories was impacted in the last quarter.

The slump in consumer confidence was driven by a quarterly drop in five out of the six measures which make up the confidence index.

Consumer confidence in disposable income and the level of debt declined by seven percentage points and four percentage points respectively, falling to their lowest level since 2014.

Spending on essential items fell by four points (12% to 8%) from the previous quarter, and discretionary spending dropped by three points (minus 4% to minus 7%).

Deloitte chief economist Ian Stewart said: “A squeeze in living standards has dented consumers’ spirits. With inflation rising to 2.9% in June, its highest level in four years, and earnings growth around the 2% mark, consumer spending power is shrinking for the first time in three years.

Consumers are not the only ones who are feeling less upbeat – business confidence has also taken a knock.

“However, we shouldn’t lose sight of the fact that some big things are going right for consumers. Unemployment is at a 40 year low, the employment rate has never been higher and interest rates – and debt funding costs – are at rock bottom levels.

“Consumers are feeling the pinch from higher inflation, but the Tracker shows that sentiment about job opportunities, career progression and job security are higher than they were a year ago.”

Ben Perkins, head of consumer business research at Deloitte, added: “We have seen a negative impact on spending for both essential and discretionary categories in the last quarter.

“However, it should be noted that whilst consumer spending is certainly slowing, record levels of employment and cheap borrowing continue, and we are far away from a total drop-off.

“Retailers are remaining competitive and are actively trying to help consumers through lower pricing, discounting and clever loyalty programmes.

“Retailers will also know that it doesn’t take much to give consumers a boost. Even a dry, hot summer may be a sufficient catalyst to lift consumer spirits in the short term.”
