Regional Market Reach: A data center presence in Harlow can effectively serve the entire South East of England, the UK's most populous and economically significant region. It is a strong location for national service and content delivery platforms.
Tax Advantage For Data Centers: The United Kingdom offers a stable and well-understood business environment with a clear corporate tax structure. While specific tax breaks for data centers are not offered, businesses benefit from this predictability for long-term financial planning and investment.
Natural Disaster Risk
The United Kingdom has a Very Low overall disaster risk profile, with an INFORM Risk score of 2.1 out of 10, as of September 2025. The risk landscape is minimal and well-managed.
Key hazard scores for the country include:
- Coastal Flood: 8.3/10
- River Flood: 5.7/10
- Drought: 1.6/10
- Tsunami: 1.9/10
While coastal flooding is a national consideration, Harlow's inland position significantly reduces its direct risk. The primary local concern is river flooding, though modern data centers are built above expected flood plains. Seismic and cyclone risks are negligible.
