AI Growth Labs: What the UK's Regulatory Sandboxes Mean for Your Sector

The UK government is launching AI Growth Labs: regulatory sandboxes where organisations can test AI applications with the relevant regulators. Legal services goes first, with applications due to open in summer 2026. Other sectors are expected to follow later in the year, according to Osborne Clarke's June regulatory outlook.

Sandboxes are easy to dismiss as innovation theatre. This programme matters because the UK regulates AI through existing sector regulators rather than one overarching statute.

The Growth Labs give organisations a formal way to resolve uncertainty with those regulators before launch. They make the sector-led model more usable in practice.

What are the UK's AI Growth Labs?

• AI Growth Labs. Regulatory sandboxes for testing AI applications, described as "a safe space in which to test innovative legal services products and discuss regulatory issues directly with regulators". Legal services first; applications open in summer 2026; rollout to further sectors later in the year.
• Cross-regulator structure. For the legal lab, the Information Commissioner's Office is collaborating with the Solicitors Regulation Authority, the Council for Licensed Conveyancers, and the Legal Services Board on cross-regulatory challenges — the data protection regulator and the sector regulators in one room.
• The wider June package. The same period brought the AI Hardware Plan (a strategy for developing and scaling the semiconductor technologies underpinning AI), a new AI Economics Institute under HM Treasury and DSIT to assess AI's impact on productivity and labour markets, and two DRCF calls for input — one on consumer attitudes to generative and agentic AI, one on tools for managing AI risks, open until 2 September 2026.

A June 2026 House of Commons Library briefing confirms the frame all of this sits in: there is no UK AI Act and no AI bill currently before Parliament. The sector-based approach is deliberate, not a gap waiting for legislation.

Who can benefit from an AI Growth Lab?

Legal services firms and legal tech vendors have the first opportunity. Suitable candidates include automated advice, AI-assisted conveyancing and agentic drafting involving client files.

A sandbox place turns regulatory uncertainty into documented dialogue with the SRA, CLC and ICO. That record may also help firms answer questions from professional indemnity insurers and risk committees.

Everyone else should treat the legal lab as a template. Its cross-regulator structure joins the data-protection regulator with the relevant sector regulators.

Identify planned AI deployments that are blocked by regulatory uncertainty. If a lab opens for your sector, you will then have a defined candidate rather than starting with a brainstorm.

Compliance and risk teams have a second opportunity through the DRCF's call for input on AI risk-management tools. It remains open until 2 September and asks which frameworks organisations use for generative and agentic AI risk.

Contributing can help shape guidance that firms may later be assessed against. As our analysis of the ICO's direction of travel explains, waiting for final guidance means accepting rules shaped by other organisations' practices.

What does participation in an AI Growth Lab involve?

A sandbox place is not a regulatory holiday. UK GDPR, professional-conduct rules and consumer law still apply. What changes is the order of operations.

Instead of launching and discovering the regulator's view later, participants test with the regulator involved. That is particularly valuable when an AI product raises a genuinely novel compliance question for which detailed guidance does not yet exist.

The cost is disclosure. Participants must show regulators their product's failure modes before launch. Applicants therefore need operational governance, not a statement of future intent.

Teams should understand system behaviour, monitor its actions and isolate the resources it can access. Those are also the infrastructure fundamentals in our guide to sandboxing agent workloads.

How should organisations prepare before applications open?

• Inventory the stuck projects. List AI deployments that stalled on regulatory uncertainty rather than technical difficulty. Those are your sandbox candidates — and if there are none, you do not need the lab.
• If you are in legal services, prepare now. Applications open this summer. A credible application will name the regulated activity in question, the specific uncertainty, and the evidence you would generate in the lab.
• Respond to the DRCF by 2 September if your AI risk framework is real. Shaping the assessment criteria beats inheriting them.
• Watch the sector rollout. The government has committed to further sectors in 2026 but not named them. When yours is announced, the legal lab's structure tells you what to expect: your sector regulator plus the ICO, jointly.

The Growth Labs are one piece of a policy estate that now spans compute, hardware, institutions, and regulation. We map the whole of it in our guide to the UK AI policy landscape.

Frequently asked questions

What are the UK's AI Growth Labs?

AI Growth Labs are government-backed regulatory sandboxes: secure environments where organisations can test AI applications and discuss regulatory issues directly with the regulators who oversee them, before committing to full deployment. The programme starts with legal services, where the Information Commissioner's Office is collaborating with the Solicitors Regulation Authority, the Council for Licensed Conveyancers, and the Legal Services Board on cross-regulatory challenges. Applications for the legal services lab open in summer 2026, with other sectors to follow later in the year.

Which sectors can apply to the AI Growth Labs?

Legal services is the first sector, with applications opening in summer 2026 for innovators building AI-enabled legal products. The government has said the programme will be rolled out to other sectors later in 2026, though it has not yet named them. Organisations outside legal services should treat the first lab as a template: the cross-regulator structure being tested there — a data protection regulator working alongside sector regulators — is the model likely to be replicated.

What do AI Growth Lab participants actually get?

A safe space to test innovative products and direct access to regulators to work through compliance questions before launch. For AI products whose regulatory treatment is unclear — automated legal advice, AI-assisted conveyancing, agentic workflows that touch client data — that direct channel is the substantive benefit: it converts regulatory uncertainty, which boards read as risk, into documented dialogue with the bodies that would otherwise enforce against you.

How do the AI Growth Labs fit into UK AI regulation?

They are the enabling half of the UK's sector-based approach. The UK has no single AI Act — a June 2026 House of Commons Library briefing confirms regulation continues to run through existing sector regulators. The Growth Labs give that model a front door: rather than a statute defining what is permitted, innovators test propositions with the relevant regulators directly. The same month brought the AI Hardware Plan, a new AI Economics Institute, and two DRCF consultations on AI risk — the sector-based model is being built out, not replaced.
