This price point is competitive within the UK and offers a slight cost advantage compared to central London, directly reducing the total cost of ownership for high-density deployments. The UK's power mix includes significant contributions from renewables (~40–50%), natural gas (~35–45%), and nuclear (~10–15%).

Market Access, Business & Tax Climate
Proximity To Key Business Districts Harlow's primary advantage is its proximity to London's financial center, the City of London, and the tech hubs around Silicon Roundabout. This allows for low-latency connectivity essential for financial services, media production, and cloud gaming companies that require rapid access to London's ecosystem.
Regional Market Reach From Harlow, businesses can effectively serve the entire South East of England, a population of over 19 million people. Its location provides an excellent base for UK-focused service delivery while acting as a gateway to continental Europe through London's international fiber links.
Tax Advantage For Data Centers The UK does not offer specific tax credits or financial incentives for data center construction or operation. Businesses operate under the standard corporate tax structure, which provides predictability for financial planning.
Natural Disaster Risk
Harlow has a very low natural disaster risk profile, with an INFORM Risk score of 2.1 out of 10, as of September 2025. This low-risk environment minimizes the threat of service interruptions from natural events, making it a reliable location for critical IT infrastructure.
The primary natural hazards, while still rated very low, include:
- Coastal Flood: 8.3 (Indirect risk from regional storm surges impacting broader infrastructure)
- River Flood: 5.7
- Tsunami: 1.9 (Extremely low probability, regional consideration)
- Drought: 1.6
