Network & Connectivity Ecosystem
Hemel Hempstead serves as a critical satellite market to London, providing resilient and diverse network infrastructure just outside the capital's core.
Carrier Density & Carrier Neutrality: With 4 facilities operated by 3 providers, the market offers access to a solid base of UK and international carriers as of September 2025. Carrier-neutral facilities provide the primary interconnection points, ensuring competitive and resilient connectivity options.
Direct Cloud On-Ramps: While there are no direct public cloud on-ramps within Hemel Hempstead itself, all major cloud providers are accessible via dedicated, low-latency links to nearby London data centers. Private network interconnects (PNI) and wavelength services connect directly to AWS, Google Cloud (GCP), and Microsoft Azure PoPs in the London metro.
Internet Exchange Points (IXPs): Peering is primarily achieved by connecting to London's major internet exchanges, such as LINX and LONAP. These connections provide efficient traffic exchange and optimized routing for reaching UK and European end-users.
Bare Metal: Bare metal server options are readily available from providers within the market. This allows businesses to deploy dedicated hardware for performance-intensive applications, with providers like Hivelocity and phoenixNAP serving the broader UK region.

Average Cost Of Power: Industrial electricity costs average approximately £0.17/kWh as of September 2025. This pricing is competitive for the Southeast England region and allows for predictable power budgeting for colocation customers.
Power Grid Reliability: The grid supporting the Hemel Hempstead area is well-engineered and benefits from the redundancy built into the UK’s national power infrastructure. Data centers in the area typically have connections to multiple substations, ensuring high levels of uptime and fault tolerance.
Market Access, Business & Tax Climate
Hemel Hempstead's strategic location provides excellent access to the UK's largest economic market while maintaining a lower operational cost profile.
Proximity To Key Business Districts: The market is situated just northwest of London along the M1 and M25 motorways, providing excellent access to Greater London and the financial districts of the City. This proximity is ideal for businesses needing low-latency performance for applications serving the capital.
Regional Market Reach: From Hemel Hempstead, organizations can effectively serve the entire population of Southern England, the Midlands, and beyond. Its location makes it a strategic hub for UK-wide content delivery and application hosting.
Tax Advantage For Data Centers: The United Kingdom does not currently offer specific tax breaks or financial incentives for data center development or operation. Businesses should plan based on standard corporate tax rates and the prevailing 20% VAT on services.
Natural Disaster Risk
Hemel Hempstead has a very low natural disaster risk profile, with an overall INFORM Risk score of 2.1 out of 10 as of September 2025. This score indicates a stable and secure physical environment for critical IT infrastructure.
The primary natural hazards to consider, though still rated as low risk, are:
- Coastal Flood: Rated 8.3/10 nationally, this poses an indirect risk to broader regional infrastructure rather than a direct threat to this inland location.
- River Flood: With a score of 5.7/10, this is the most direct local hazard, though modern data centers are built above flood plains to mitigate this risk.
- Drought: A score of 1.6/10 indicates a minor long-term risk.
- Tsunami: Rated 1.9/10, this is not a material risk for an inland location.
Risks from earthquakes (0.1/10) and tropical cyclones (0/10) are negligible.
