◆ THE SHORT ANSWER

Yes. You can rent B300 GPUs in the UK now through vetted partners, contracted directly with the operator running your nodes. On B300 price per hour, the median on-demand rate was $7.50 across 11 tracked providers as of 11 September 2026, with the market spanning $6.50 to $15.00 and hyperscaler rates reaching $17.80. Blackwell Ultra capacity is now broadly available across hyperscalers and sovereign facilities in Europe, and UK operators have been building out the liquid cooling B300's 1,400W top bin requires alongside the rest of the region. The UK also retains EU data adequacy, so EEA personal data can be processed here without standard contractual clauses. If you need more memory at a lower power draw, B200 in the UK is worth comparing; for smaller workloads, H100 and H200 in the UK remain the cheaper, more established options.

◆ PRICING

What B300 costs in the UK

B300 price per hour here reflects the tracked wholesale market, not a fixed list price. Term length matters more than usual given the liquid cooling premium built into UK facilities for this generation; ask for both a short-term and long-term quote before deciding.

Market reference ranges as of 11 September 2026, quoted in USD, not UK-specific quotes. B300's higher liquid-cooling requirement adds a premium not present on earlier generations.

Where B300 capacity earns its keep

The workloads the UK's B300 supply is built for.

The UK also retains EU data adequacy, so EEA personal data can be processed here without standard contractual clauses, the same advantage that applies across every generation covered on this site. Blackwell Ultra rollout across Europe has moved faster than the prior generation did at the same stage, with hyperscalers and sovereign facilities both now carrying B200 and B300 broadly. For UK buyers, B300 is bought for FP4 capability and the 288GB memory ceiling, not for being the cheapest or fastest generation to source.

/01

Frontier reasoning at scale

Train frontier-scale models that need the full 288GB memory ceiling, where B300's 15 PFLOPS of dense FP4 compute and higher memory bandwidth reduce the GPU count needed for a given run.

HGX B300 · 288GB · NVFP4

/02

70B+ inference, no sharding

Serve 70B and larger models without sharding across GPUs, since B300's memory headroom avoids the communication overhead that erodes throughput on split deployments.

/03

Long-context without offload

Run long-context inference and reasoning chains without offloading KV cache to slower memory, holding more context in-GPU than any prior generation.

/04

High-density agentic serving

Serve high-concurrency agentic workloads where token throughput per GPU, not just raw FLOPS, decides your cost per request.

Frequently Asked Questions

Can I rent B300 GPU cloud capacity in the UK?

Yes, through vetted partners with UK placement, contracted directly with the operator. Blackwell Ultra capacity is now broadly available across hyperscalers and sovereign facilities in Europe. Tell us your requirement and we will confirm availability within 24 hours.

How much does B300 cost per hour in the UK?

The B300 price per hour globally had a median on-demand rate of $7.50 across 11 tracked providers as of 11 September 2026, with the market spanning $6.50 to $15.00 and hyperscaler rates reaching $17.80. Wholesale rates through GPUaaS.com are quoted per enquiry and vary by commitment term, configuration and placement.

What makes UK B300 supply different from other markets?

The UK carries the same broader European Blackwell Ultra rollout as its neighbours, with the addition of EU data adequacy for EEA personal data, a distinction not every European market offers.

Does UK data protection law affect B300 deployment?

The UK retains EU data adequacy, so EEA personal data can be processed here without standard contractual clauses, simplifying deployment for EU-facing workloads.

Is B300 more expensive in the UK than other markets?

UK industrial power costs are among the highest of major markets, which tends to push UK rates toward the upper half of the range shown above, consistent with every other generation covered here.

Which workloads suit B300 in the UK specifically?

Frontier-scale training and high-concurrency reasoning inference needing the 288GB memory ceiling, particularly for EU-facing workloads that benefit from UK data adequacy.
