The UK economy shrank in October as the manufacturing and construction sectors were hit by poor weather.

Gross domestic product (GDP) is thought to have fallen 0.3% during the month, down from 0.2% growth in September, the Office for National Statistics (ONS) said.

It came as all three of the main sectors that the ONS tracks fell into negative territory for the first time since July. Economists had expected GDP to contract by just 0.1%.

“October … saw contractions across all three main sectors,” said ONS director of economic statistics, Darren Morgan.

“Services were the biggest driver of the fall with drops in IT, legal firms and film production – which fell back after a couple of strong months.

“These were also compounded by widespread falls in manufacturing and construction, which fell partly due to the poor weather.”

Economists said despite the fall it would be premature to say the country is headed into a recession. Thomas Pugh at consulting firm RSM UK said that a drop-off in inflation and rising wages would likely boost the economy in the last two months of the year.

“In any case, the big picture is still one of a stagnating economy,” he said.

“We doubt growth will materially pick up until towards the end of next year, meaning that the spectre of recession will hang over the UK economy for a long time yet.”

Federation of Small Business chair Martin McTague said that the figure was “disappointing news” that “will leave many feeling flat.”

While the larger services sector contributed the most to the slowdown in October, the production sector fell the most rapidly.

It saw output down by 0.8% thanks to a slowdown in manufacturing caused in part by the computer, electronics and optical products sectors.

Meanwhile, the construction sector was hit by one of the rainiest Octobers in the last 200 years.

“The ONS also noted that it had received comments from consumer services firms that demand was lower than usual as a portion of the half-term holidays in some areas fell in November this year,” said Samuel Tombs, chief UK economist at Pantheon Macroeconomics.

The worse-than-expected reading comes as the Bank of England is to set a new interest rate on Thursday.

Decision-makers at the Bank were already unlikely to raise interest rates at this week’s meeting. The ONS data will give them even more certainty that rates are high enough to be “restrictive” and dampen the economy.

They are also aware that the full effect of their recent spate of interest rate hikes has not yet been felt.

People who have taken out new mortgages, have had to remortgage their properties or who are on a tracker mortgage will have seen their monthly payment rise significantly.

About five million mortgages will still be up for renewal by the end of 2026. So far these people have avoided the hit of rising interest rates.

But the rate setters on the Monetary Policy Committee (MPC), including Bank governor Andrew Bailey, have stressed repeatedly that it is far too soon to talk about cutting rates.

“October’s drop in GDP adds to the growing list of recent downside data surprises, but we still doubt that the MPC will change its tune and signal its willingness to cut Bank Rate next year as soon as this week’s meeting,” Mr Tombs said.

Shadow chancellor Rachel Reeves said that the data shows that the Prime Minister was not growing the economy.

“Rishi Sunak ends the year having failed to deliver on his own promise to grow the economy. Economic growth is going backwards leaving working people worse off,” she said.

“After 13 years, the Conservatives have failed on the economy and after the chaos of the past few weeks Rishi Sunak is clearly too weak to deliver for Britain.”

Chancellor of the Exchequer Jeremy Hunt said: “It is inevitable GDP will be subdued whilst interest rates are doing their job to bring down inflation.

“But the big reductions in business taxation announced in the autumn statement mean the economy is now well placed to start growing again.”
