THE UK is set to see a sharp slowdown in economic growth as mounting supply chain crisis and staff shortages, largely blamed on Brexit, threaten to derail Britain’s recovery, according to a major business group.

The British Chambers of Commerce (BCC) warned there is also a “real danger” the UK Government’s health and social care levy could further stifle the economic bounce-back from the pandemic.

It comes after the UK Government announced a 1.25% national insurance tax hike to raise £12 billion to help fund England's NHS backlog and social care system.

The BCC slashed its forecast for third-quarter growth to 2.8% from 3.5% previously as it said the supply chain disruption and hiring difficulties are offsetting the boost from July’s full lifting of coronavirus restrictions.

It added that growth – which stood at 4.8% in the second quarter – is predicted to ease back further to 1.6% between October and December.

Official figures tomorrow are expected to show a further slowdown in growth over July, with most economists pencilling in 0.5% expansion, down from 1% in June.

The supply and lorry driver woes, as European workers chose to leave the UK after Brexit, have left supermarket shelves increasingly bare in recent weeks and are hitting sectors from hospitality to housebuilding.

The BCC said the lorry driver shortage, global supply issues and wider recruitment troubles are set to hamper the rebound and mean the economy will only return to its pre-pandemic level in the first quarter of 2022.

Suren Thiru, head of economics at the BCC, said the group’s latest forecast “points to a loss of momentum in the coming months as staff shortages, supply chain disruption and rising cost pressures limit output from many sectors”.

He cautioned: “A prolonged period of acute supply and staff shortages could derail the recovery by forcing firms into a more permanent reduction in their operating capacity, eroding their ability to fulfil orders and meet customer demand.”

He added: “There is a real danger the National Insurance increase announced this week could stifle the recovery. Any further tax changes could very well prolong the economic damage from Covid.”

A spokesman for the UK Government said most of the solutions to the HGV drivers shortage are “likely to be driven by industry, with progress already being made in testing and hiring, and a big push towards improving pay, working conditions and diversity”.

It has launched measures including streamlining the HGV licence process, but faces calls to do more, such as introducing a temporary visa for EU drivers.

The BCC said that despite the 2021 economic rebound, business investment is expected to decline by 2.5% this year, which could be the “weak point of the recovery because it undermines the UK’s ability to raise productivity and increase our long-term growth prospects”.

It also echoed recent forecasts from the Bank of England that surging inflation is set to peak at 4% in the fourth quarter and said interest rates are likely to start rising at the end of 2022 with a second due a year later.
