Introduction
US cloud providers — AWS, Azure, and Google Cloud — dominate the market. But for UK businesses, the total cost of using these platforms goes far beyond the listed instance prices. Egress fees, currency exchange, VAT treatment, and compliance overhead can add 30-60% to your bill.
In this analysis, we break down the real cost of US cloud for UK businesses and compare it to UK-based alternatives.
The Egress Tax
The single biggest hidden cost when using US cloud providers from the UK is egress (data transfer out). AWS charges $0.09/GB for the first 10 TB/month egress to the internet. For a UK business serving UK customers, every byte of data flowing from US cloud servers to UK users incurs this charge.
Real example: A SaaS platform serving 500 GB/month of API responses and assets would pay $45/month in egress fees alone — on top of compute and storage costs. With a UK provider, that same traffic stays within the UK network, often with no egress charge.
Currency Exchange Impact
US cloud providers bill in USD. With GBP/USD exchange rates fluctuating between 1.24 and 1.35 in 2024-2025, your actual cost in GBP can vary significantly month to month. At the current rate of ~1.25, a $1,000 cloud bill actually costs £800 — but if the pound weakens to 1.15, that same bill becomes £870.
UK providers bill in GBP, giving you predictable costs regardless of currency markets.
VAT and Tax Considerations
AWS and Azure charge UK VAT (20%) on all services consumed by UK businesses. However, the way it's applied can cause cash flow issues — especially for businesses on annual accounting or the Flat Rate Scheme. UK providers apply VAT transparently as part of your invoice.
Compliance Overhead
For UK businesses handling personal data, GDPR compliance when using US cloud providers requires:
- Standard Contractual Clauses (SCCs) with each provider
- Data Protection Impact Assessment (DPIA)
- Transfer Impact Assessment (TIA)
- Potential need for UK Representative appointment
- Ongoing monitoring of Schrems II developments
With a UK-based hosting provider like Hostingowy, your data never leaves UK jurisdiction — no transfer assessments needed.
True Cost Comparison: US Cloud vs UK VPS/Dedicated
| Cost Component | AWS (US) | Hostingowy (UK) |
|---|---|---|
| 4 vCPU / 16 GB RAM | $70-120/mo | £49/mo VPS / £89/mo dedicated |
| 500 GB egress/mo | $45/mo | £0 (unmetered) |
| Managed database | $50-150/mo | Self-managed (included) |
| Load balancer | $20-50/mo | Self-configured (HAProxy/Nginx) |
| Snapshot backups | $10-30/mo | £5/mo |
| Monthly Total (typical SaaS) | $200-400/mo | £50-150/mo |
When US Cloud Still Makes Sense
There are legitimate reasons to use US cloud providers:
- Global presence: If you need data centres on multiple continents, AWS/Azure/GCP have the broadest reach
- Serverless/AI services: Lambda, SageMaker, Bedrock — these managed AI services are hard to replicate on bare metal
- Compliance certifications: AWS has more certifications than any UK provider (though most UK businesses only need ISO 27001 and SOC 2)
Hybrid Approach: Best of Both
Many UK businesses adopt a hybrid strategy: core compute and storage on UK providers (saving 40-60%), with selective use of US cloud for specialised services. This gives you the cost advantage of local hosting with the flexibility of cloud when you need it.
Conclusion
The "real cost" of US cloud for UK businesses is 30-60% higher than the headline instance price when you factor in egress, currency, VAT, and compliance. For most UK businesses running standard web applications, a UK-based VPS or dedicated server provider delivers equivalent performance at a fraction of the cost.
