The Quantum Leap: Is Quantum The UK’s Next Big Sector?
The UK’s quantum industry had a standout year in 2024 with record-breaking investment. As breakthroughs in quantum computing, sensing, and communication move from research labs to real-world applications, the sector is evolving from a niche area of physics into a cornerstone of the UK’s innovation economy.
Over £337m was invested into quantum companies last year — the highest annual total to date — signalling growing confidence from both private investors and government programmes. And with the UK committing £500m in new funding to strengthen its national quantum capabilities, momentum is only set to build.
But as we move through 2025, questions remain: which quantum subsectors are closest to commercialisation? Where are investors placing their bets? And how can professional advisors, from law firms to strategy consultants, use this data to identify emerging opportunities?
In this article, we’ll explore the state of the UK’s quantum industry, the companies leading the charge, and how Beauhurst’s data can help you uncover insight in one of the UK’s fastest-developing deep tech sectors.
What is quantum technology?
Quantum tech applies the science of how particles behave at the smallest scale to build faster computers, smarter sensors, and ultra-secure communications.
For the UK, it represents a strategic growth area, supported by billions in government investment, with the potential to transform industries from healthcare to defence and cement the country’s position as a global innovation leader.
Record breaking investment into quantum technology: the UK’s quantum sector at a glance
Last year the quantum industry saw record breaking investment — £337m was invested into quantum companies in 2024, and this amount has been growing every year since 2021. There was also a record number of company foundations in 2024, with 32 quantum companies set up.
However, since the beginning of 2025, things may have started to decline. There’s only been £55.5m invested in quantum companies so far this year, which means by the end of the year, we could see funding for these companies sink to its lowest since 2021.
That being said, with the government’s commitment to invest £500m into quantum computing companies over the next four years, we’re still likely to see a lot more growth in this sector.
Overall, there are 207 active quantum companies in the UK, over 10% of which are university spinouts (24). This is reflected in the top funders for UK quantum companies, with Oxford Science Enterprises both investing the most and contributing to the highest number of fundraisings.

Which quantum subsectors are breaking out?
Quantum sensing
According to our data, there has been £35.1m invested into the UK-based quantum sensor companies since 2018, with companies like Delta-g, Aquark Technologies, and Quantum Science at the receiving end of that investment.
These firms are using quantum effects to develop ultra-precise sensors, from navigation systems that don’t rely on GPS to medical imaging tools that can detect disease earlier. Because these technologies are already moving out of the lab and into pilot projects, quantum sensing is likely to be the first area to reach widespread commercial adoption.
Quantum sensing
As data privacy and cybersecurity become national priorities, quantum communication is gaining ground. UK companies such as Arqit and Nu Quantum are pioneering encryption systems that use quantum principles to secure information transfer, making them virtually immune to hacking.
This subsector has benefited from strong government and defence interest, with projects supported by Innovate UK and the National Quantum Technologies Programme. While the technology is still early in deployment, its strategic importance for both national security and financial services means demand is expected to grow quickly over the next few years.
Quantum computing
We can’t speak about quantum subsectors without speaking about quantum computing — the most high-profile, but also the most technically challenging field.
The UK government has committed to invest £500m into quantum computing over four years to strengthen national security and economic resilience. The UK’s £500 million quantum funding package aims to accelerate hardware development, research, and real-world testing across academia and industry. It follows earlier measures such as £100 million for five regional quantum hubs and the creation of the National Quantum Computing Centre (NQCC), the cornerstone of the UK’s quantum infrastructure.
Some of the UK’s big players include Oxford Quantum Circuits, Riverlane, and ORCA Computing. These companies are building the hardware and software needed to perform calculations that are impossible for today’s classical computers, from simulating new materials to optimising supply chains.
While full commercial applications are still a few years away, the UK’s investment ecosystem for quantum is maturing fast. In short, quantum computing remains a long-term bet, but one that’s drawing serious backing.

How advisors can use Beauhurst to find quantum companies and what to do with that data
Why should professional advisors care about the growth of quantum technology in the UK?
Quantum technology is no longer just an academic pursuit — it’s on its way to becoming a commercial reality. As quantum startups attract funding and partnerships, they’ll increasingly need legal, financial, and strategic support. For advisors, understanding this space early creates opportunities to build relationships with some of the UK’s most innovative future clients.
Which types of advisory firms are best placed to support quantum companies?
Law firms can assist with IP protection, licensing, and collaboration agreements.
Accountants and corporate finance teams can help structure grants, R&D tax claims, and investment rounds.
Consultancies and strategy advisors can guide commercialisation and market entry.
Quantum startups often begin as spinouts with complex funding and ownership structures — meaning trusted advisors play a critical role early on.
Using Beauhurst to find quantum companies
With Beauhurst’s industry data, finding niche companies such as those in the quantum sector is easy. Simply navigate to the Advanced Search, and select:
- Location > United Kingdom
- Companies House status > Active
- What the company does > Industries and buzzwords > Quantum
From here, you’ll get a list of 207 companies. But you might want to narrow down that list even further.
For example, if you’re a consultancy or strategic advisor, you might want to find quantum companies that are both academic spinouts and showing signs of rapid growth. That’s because these are often the businesses beginning to commercialise and seek external expertise.
