A new calculator from the British Chambers of Commerce reveals the cumulative hit from a decade of policy changes, as ministers prepare for a crucial autumn Budget.

The British Chambers of Commerce has warned of a "cost of business crisis" after calculating that domestic government policies have driven up the average firm's overheads by 70 per cent since 2016. A typical mid-sized company, turning over roughly £5 million and employing about 50 people, now pays an extra £827,000 a year as a direct result of those decisions, according to a new cost calculator the BCC shared exclusively with City AM.
The single biggest contributor is the employer national insurance rise announced in the 2024 Budget. The measure lifted the contribution rate from 13.8 per cent to 15 per cent and lowered the earnings threshold at which the levy kicks in to £5,000. That change alone accounts for around a quarter of the total cost increase and was designed to raise an additional £25 billion annually for the Treasury.
Successive increases to the National Living Wage under both Conservative and Labour governments, together with the expansion of auto-enrolment pension obligations, which now require employers to contribute three per cent of qualifying earnings, make up the "overwhelming bulk" of the remaining burden. David Bharier, deputy director at the BCC, said the compounding effect has priced many firms out of growth.
Many SMEs are caught in a risk-aversion cycle, where years of compounding cost pressures and geopolitical shocks have bred a defensive posture, a loss of confidence that the environment rewards taking productive risk.
The chamber has distributed its calculator to member firms as part of a push to pressure the new administration ahead of the Labour Party conference and the 28 October Budget. Andy Burnham, the Labour leader, has pledged to be "pro-business", while Chancellor John Healey has promised "breathing space" for companies. Bharier argued that every new policy should face a "growth delivery test" to prove it helps firms invest, innovate or expand.
The conciliatory tone echoes promises made before the election, when the previous chancellor vowed to lead the "most pro-business government this country has ever seen". Yet economists warn the fiscal arithmetic may force another round of tax rises. Capital Economics expects hikes "almost as big" as the £65 billion raised across the last two budgets, though the burden this time may fall more heavily on households while certain business reliefs are withdrawn.
A government spokesperson pointed to the small business plan and a £4.3 billion business rates support package, adding that 900,000 employers, more than 40 per cent of the total, are projected to pay no employer NICs by 2030-31. The BCC's calculator, however, makes clear that for the mid-market firms driving much of the UK's productivity, the cumulative cost of a decade of policy choices is already reshaping investment decisions.
