A persistent slowdown in activity among private sector firms could weigh on economic growth over the coming months, with businesses set to cut staff and raise prices, according to a survey.

The upcoming increase to national insurance contributions has prompted firms to assess their budgets urgently, the Confederation of British Industry (CBI) said.

Output across the private sector is expected to drop over the next three months, having fallen over the previous three-month period, the survey found.

Activity has been flat or falling since the middle of 2022, reflecting a prolonged period of stagnation.

The CBI, a membership organisation which represents large chains through to small businesses, surveyed 990 firms between December and January.

The survey suggested that sentiment among businesses dipped in the aftermath of the Government’s autumn Budget.

Some respondents highlighted that the tax rises had resulted in them reviewing their budgets at short notice and taking steps to mitigate higher costs.

Plans include raising prices to pass on additional costs to clients, trimming investment plans and cutting staff to reduce business expenses.
