Britain’s pharmaceutical sector, once a magnet for global investment and a leader in medical innovation, is facing a crisis of confidence. On August 27, 2025, Johan Kahlström, the UK managing director of Swiss pharmaceutical giant Novartis, delivered a stark warning: Britain has become “uninvestable” due to what he called outdated and uncompetitive drug pricing policies. His remarks, reported by Yahoo Finance and echoed on BBC Radio 4’s Today programme, have sent ripples through the industry and raised urgent questions about the future of the UK’s life sciences sector.
At the heart of this dispute lies a government policy designed to control the cost of branded medicines for the National Health Service (NHS). The voluntary agreement, which includes a rebate scheme, caps how much the NHS spends on these drugs each year. If spending exceeds a set threshold, pharmaceutical companies are required to pay back a portion of their revenues through rebates. While this might sound like prudent fiscal management, pharmaceutical leaders argue the system has become a major deterrent to innovation and investment.
The government’s decision to raise the rebate rate for newer medicines to nearly 23% for 2025 has drawn particular ire from the industry. According to analysis from the IndexBox platform, the UK’s pharmaceutical market has experienced slowed growth in recent years, with investment figures lagging behind other major economies. Executives say these high rebates—far above the single-digit rates common elsewhere in Europe—are squeezing manufacturers and making Britain a less attractive destination for capital allocation and research facilities.
“We have seen an incredibly challenging environment when it comes to both our ability to bring new medicines in a sustainable way to patients in the UK, and in our ability to attract inward life science investments into a sector which has been poised by the Government as a key growth driver for the economy,” Kahlström told BBC Radio 4. “So in international comparison, the UK, unfortunately, has become largely uninvestable at this stage.”
The numbers back him up. The UK has missed out on investments worth tens of billions of pounds, according to Novartis and other industry voices, as companies direct their resources to markets with more favorable environments. A recent $23 billion investment by Novartis into the United States stands as a stark example of what the UK could have attracted under different circumstances. “We’re making significant investments in markets that value innovation, markets like the US, China and Japan, and we recently announced a $23bn investment into the [US] and it’s not lost on me, the fact that under different circumstances and with a more innovation-friendly environment, I think the UK could have been a worthy contestant for those investments,” Kahlström said.
The government, however, is standing its ground. Health Secretary Wes Streeting walked away from talks with the pharmaceutical industry last week after the two sides failed to strike a new pricing deal. Streeting has vowed not to let pharmaceutical companies “rip off” taxpayers, a stance that resonates with many who are wary of rising healthcare costs. The Department of Health launched a review of NHS rebates earlier this year, a move partially influenced by pressure from former US President Donald Trump, who has called for lower drug prices in the United States—where costs are substantially higher than in the UK and Europe.
The government’s approach is rooted in a desire to keep the NHS sustainable and ensure that taxpayers are not overburdened by the cost of new medicines. The voluntary agreement currently in place allows the total NHS bill for branded medicines to rise by a certain percentage each year, but if spending exceeds that limit, the clawback mechanism kicks in. This policy, officials argue, helps keep the NHS affordable for everyone while still allowing for some growth in spending on new treatments.
Yet, pharmaceutical executives insist that such a high rebate rate is out of step with global norms and is having a chilling effect on investment and innovation. They argue that rebate rates in the single digits, as seen in other European countries, are necessary to foster a healthy environment for research and development. “Pharmaceutical bosses have warned the scheme is preventing the launch of cutting-edge medicines in the UK,” according to reporting from Yahoo Finance. The result, they say, is that British patients may not have timely access to the latest therapies, and the country risks losing its status as a leader in life sciences.
The impact is already visible in market data. The IndexBox platform’s analysis shows that the UK’s pharmaceutical market has experienced slowed growth, with investment figures trailing those of other major economies. The pricing environment has been consistently cited as a primary factor deterring capital allocation for new manufacturing and research facilities. As the government raised the rebate rate to almost 23% for 2025, industry leaders have pressed for a reduction to single digits, warning that the current regime is stifling innovation and preventing the launch of next-generation medicines.
There are, of course, two sides to every story. While pharmaceutical companies argue that high rebates are driving away investment and innovation, government officials maintain that their primary responsibility is to British taxpayers and the sustainability of the NHS. Streeting’s vow not to let companies “rip off” the public reflects a broader skepticism about the motives of large pharmaceutical firms, especially given the high-profile debates over drug pricing in the US and elsewhere.
Meanwhile, the Department of Health’s ongoing review of NHS rebates signals that the government is at least willing to consider changes, though it remains committed to its core objective of controlling costs. The challenge will be finding a balance that both encourages investment in the UK’s life sciences sector and protects the interests of patients and taxpayers.
For now, the standoff continues. Pharmaceutical executives warn that unless the UK adopts more competitive policies, it will continue to miss out on vital investment and risk falling behind in the global race for medical innovation. The government, on the other hand, insists that it cannot allow companies to dictate terms at the expense of public funds. The stakes are high: the outcome will shape not just the future of the UK’s pharmaceutical industry, but also the health and wellbeing of millions of British patients.
As both sides dig in, the UK finds itself at a crossroads—caught between the imperatives of fiscal responsibility and the need to remain a global leader in life sciences. The next steps taken by policymakers and industry leaders will determine whether Britain can reclaim its place as a top destination for pharmaceutical investment, or whether it will continue to see capital and innovation flow elsewhere.
