The UK’s Food Standards Agency has launched a regulatory ‘sandbox’ to accelerate the regulatory approval pathway for cultivated meat, with eight startups participating in the two-year programme.
Weeks after cultivated meat hit pet food shelves in the UK, the government has launched a first-of-its-kind regulatory programme to help cultivated meat producers get to market faster – and for cheaper.
The Food Standards Agency (FSA) – which oversees food safety and novel food regulation in the UK – has picked eight cultivated meat startups to participate in the regulatory ‘sandbox’, where they will work with scientists, regulatory experts, and academic bodies to overhaul the regulatory framework around these products.
It comes months after the Department of Science, Innovation and Technology awarded £1.6M to the FSA to create the Cell-Cultivated Products Regulatory Sandbox, as part of the first round of its Engineering Biology Sandbox Fund.
Sandboxes comprise controlled environments for situations where scientific and technological innovation has outpaced existing regulation – many companies are currently making cultivated meat, but the UK’s authorisation process (modelled on the EU’s) is slow and congested. These sandboxes run for a limited period to help startups, researchers and regulators work together to develop new rules, standards and guidance.

The two-year programme includes startups from across the world: Hoxton Farms, Roslin Technologies, Uncommon Bio (all UK), BlueNalu (US), Vow (Australia), Mosa Meat (The Netherlands), Gourmey (France), and Vital Meat (France) – the latter two, along with British startup Ivy Farm Technologies and Israel’s Aleph Farms – are already waiting on approval for cultivated meat in the UK. London-based Meatly is the only one to have received the green light, though this is for pet food.
“By participating in the sandbox, we aim to accelerate our regulatory timeline for the UK market, reducing potential delays and strengthening our submission,” said Mosa Meat. Its founder and CSO, Dr Mark Post, added: “These are exactly the kind of public-private partnerships we envisioned when we debuted the world’s first cultivated burger right here in London in 2013.”
Prof Robin May, chief scientific advisor at the FSA, noted: “Safe innovation is at the heart of this programme. By prioritising consumer safety and making sure new foods, like cell-cultivated products are safe, we can support growth in innovative sectors. Our aim is to ultimately provide consumers with a wider choice of new food, while maintaining the highest safety standards.”
How the regulatory sandbox will help cultivated meat startups

For years, food safety regulation in the UK was stuck in the pre-Brexit novel food regulations, which are slow and expensive for companies. Currently, regulatory filings cost between £350,000-£500,000 per product, and can take more than two-and-a-half years to be approved.
Over the last year, the government has made concerted efforts to put the UK at the front of the protein transition race. The FSA first announced plans to create a sandbox in February 2024, after a report it commissioned revealed that speeding up novel food regulation could help it meet national climate plans.
Regulatory sandboxes allow companies to test new concepts with real customers under the supervision of a regulator, as designed by the UK’s Financial Conduct Authority. The Cell-Cultivated Products Regulatory Sandbox will be jointly run by the FSA and Food Standards Scotland (FSS), and provide application guidance to startups, expand the safety and nutritional knowledge of novel foods, and reduce approval timelines.
The FSA will gather “rigorous scientific evidence” about the technology behind cell-cultured food products to better understand and regulate these products. They will address important questions – including about labelling – and apply up-to-date insights when clearing novel foods for sale.
The regulator has previously said it expects at least 15 more applications in the next two years, and predicts that many more cultivated protein startups could crop up thanks to the development.
“By supporting the safe development of cell-cultivated products, we’re giving businesses the confidence to innovate and accelerating the UK’s position as a global leader in sustainable food production,” said science minister Sir Patrick Vallance.
UK steps up its protein transition efforts

The regulatory sandbox is among a number of developments that signal the UK’s intention to spearhead sustainable protein innovation. It has invested £75M for the development of these foods, an important outlay considering it is behind its net-zero target, and meeting this would require Brits to cut 35% of their meat consumption by 2050, according to the national Climate Change Committee (CCC).
Since 2023, four major research centres have cropped up – the Cellular Agriculture Manufacturing Hub (CARMA), the National Alternative Protein Innovation Centre (or NAPIC, helped by a £15M injection from the government), the Microbial Food Hub, and Bezos Earth Fund‘s Centre for Sustainable Protein.
The FSA is working with CARMA, NAPIC and the Centre for Sustainable Protein as part of the sandbox, with non-profit the Good Food Institute (GFI) Europe and trade body the Alternative Proteins Association also involved.
Additionally, the regulator will set up a system of international cooperation, which would see the UK greenlight cultivated meat products approved in other countries. And it’s creating a new public register to replace the existing system of requiring a statutory instrument (which adds up to six months to the assessment process), and removing the need for renewals of approvals every 10 years.

Further, cultivated meat is on the radar of the newly opened Regulatory Innovation Office, whose engineering biology focus involves reducing red tape and helping regulators bring these products to market faster.
“We are very pleased that the UK is moving forward with this two-year programme and are excited about the prospect of a full safety assessment of two cultivated meat applications within that time,” Valentina Gallani, health and nutrition manager at ProVeg International, told Green Queen.
She added that this will allow the UK to catch up with other countries that have greenlit cultivated meat and ensure it’s ahead of the pack. “Cultivated meat can be a promising way to diversify protein consumption, boost the economy and increase food security towards a more sustainable food system. To do so, it is important to have a rigorous regulatory approval process to protect the consumer and support the industry.”
Challenges remain, but sandbox a big step forward

Last month, Meatly and fellow London startup The Pack debuted dog treats featuring cultivated meat and plant-based ingredients at Pets At Home, marking the first time Brits could buy cell-cultured products, albeit for their pets.
Cultivated meat has been cleared for sale in Singapore, the US, Israel and Hong Kong, while Regulators in the EU, Switzerland, Australia and Thailand are evaluating applications too. And just last week, the US issued its third approval, for cultivated pork producer Mission Barns.
Several European countries – some bound by EU regulations – have already held public tastings for cultivated meat, a feat yet to be achieved in the UK. Plus, some citizens on a CCC panel said they’re uneasy about cultivated meat, though they added the government could still support these to ensure a larger range of products. The committee itself associated these proteins with “potential positive nutrition and health impacts”, while even farmers are open to the idea of cell-cultured meat.
“While the sandbox is a welcome measure, other challenges still remain. The FSA has been under-resourced for a number of years – resulting in lengthy delays for product approvals – and the detailed guidelines for alternative protein startups first proposed in 2022 have yet to be published, meaning some companies lack the clarity needed when preparing dossiers,” Linus Pardoe, senior UK policy manager at GFI Europe, told Green Queen last month.

“The UK has also not yet introduced a modern approach to holding safe, limited taste testing for novel foods, similar to the protocol introduced by the Netherlands – another area that could enable startups to demonstrate progress and engage with consumers as they develop their products.”
“The sandbox will only be considered a success if the FSA also receives the support and funding to complete its assessments within faster timelines. Without this speed, it risks losing out on creating a competitive homegrown industry which can power low-carbon economic growth, boost food security, and ensure the UK becomes a leader in net-zero within the food industry,” said Jim Mellon, executive chairman of cellular agriculture investor Agronomics (a Meatly shareholder).
Still, the launch of the sandbox and the collaboration with leading cultivated meat players – chosen to represent a “diverse, international range of technologies, processes, and ingredients” – is a major step in the right direction for the UK.
“We’ve seen in a recent report that the UK is falling behind in terms of agritech funding, yet houses leading companies in this industry,” added Mellon. “We’re certain that with a modern and efficient regulatory framework, we could easily match if not surpass rival markets and the reward will be increased food security from a sustainable and durable source.”
