How Much Does Data Migration Cost?
17 April 2025The cost of establishing a data centre can vary significantly based on several key factors. On average, construction costs range from £600 to £1,100 per square foot.
When considering investment per megawatt, figures typically fall between £7 million and £12 million. For large data centres, annual operating expenses usually range from £10 million to £25 million.
Regional variations also influence costs. In the United States, the average cost is approximately £9.5 million per megawatt, whereas in Europe, it is around £14 million.
Additionally, the type of facility, construction timelines, and the complexity of electrical systems can significantly impact overall expenses.
To gain a clearer understanding of total costs, it is essential to consider these factors comprehensively.
Overview of Data Centre Costs
Contents
When evaluating the costs associated with establishing a data centre, it is essential to recognise the significant range of expenses involved. The following key factors play a crucial role in determining these costs:
- Construction Costs: The expense of building a data centre generally falls between £600 and £1,100 per gross square foot. Effective planning and execution, including a comprehensive infrastructure assessment, can help manage costs and minimise the risk of overspending.
- Commissioned IT Load: The average investment per megawatt ranges from £7 million to £12 million, with larger facilities potentially incurring costs as high as £12 million per megawatt.
- Ownership Costs: Annual operating expenses for large data centres can vary from £10 million to £25 million, encompassing power, cooling, and property taxes.
- Geographic Variation: Costs can differ significantly based on location. For instance, the average cost in the UK is around £9.5 million per megawatt, while Europe averages £14 million, and the Asia-Pacific region is at £12 million per megawatt.
Building In-house Data Centres
Building in-house data centres offers organisations a strategic advantage by providing greater control over their IT infrastructure and resources. However, the financial implications can be considerable.
In addition to constructing the physical facility, it is essential for organisations to understand the Data Centre Migration Process and Key Steps to ensure a seamless transition of their existing systems.
Here are some key points to consider:
- Construction Costs: The average expense for building a small data centre is approximately £1,000 per square foot. For commercial facilities, total costs can range from £10 million to £12 million per megawatt.
- Initial Deployment Costs: These are crucial and are influenced by the organisation's technological requirements and specific business needs.
- Networking Expenses: Establishing fibre connections can significantly increase the budget, with costs potentially adding thousands of pounds per mile.
- Construction Timeline: The timeline for single-tenant facilities generally falls between 12 to 24 months, whereas co-location options may be operational in just a few weeks.
- Lifecycle Consideration: To maximise scalability, organisations should plan for a data centre lifecycle of ten years or more, steering clear of unnecessary overbuilding.
Factors Influencing Costs
Establishing a data centre involves various costs influenced by multiple factors, making it crucial for organisations to assess each element thoroughly. Here are the key considerations that can significantly impact expenses:
- Stakeholder Engagement: Involving stakeholders early on is vital for collaborative decision-making. This approach helps to minimise disruptions and ensures everyone is on the same page throughout the process.
- Construction Costs: The average cost for small data centres is about £1,000 per square foot. In contrast, larger facilities may require investments between £10 million and £12 million per megawatt.
- Electrical Systems: These systems are a major expense, constituting approximately 40% to 45% of total costs. This includes essential components such as generators and Uninterruptible Power Supply (UPS) systems.
- Geographic Location: Costs can vary significantly based on location. For instance, the average cost in the U.S. is around £9.5 million per megawatt.
- Tier Certification: Higher-tier data centres, like Tier IV, can incur costs of about £25,000 per kW due to their enhanced redundancy features.
- Additional Factors: Considerations such as power density, redundancy requirements, and the urgency of the project can further influence costs. Careful planning is crucial to manage these expenses effectively.
Types of Data Centres
Understanding the various types of data centres is crucial for organisations aiming to maximise their infrastructure investments. Here are the main categories:

– Retail Colocation Data Centres: These facilities cater to multiple customers with smaller power requirements (under 1 MW). Although they often come with higher costs—illustrated by CoreSite's £16.3 million investment per megawatt—they offer flexibility and scalability for growing businesses. This makes them a popular choice, particularly for smaller organisations.
Effective communication is essential during any relocation process to ensure smooth operations.
– Wholesale Data Centres: These centres are leased to a single customer or a limited number of tenants, enabling standardised construction that lowers build costs. A prime example is Digital Realty's substantial £3.86 billion investment for 321 MW.
Wholesale data centres are perfect for larger companies seeking dedicated space and greater control over their infrastructure.
– Brownfield Developments: These projects leverage existing infrastructure, offering cost benefits compared to greenfield sites, with potential savings of 10% to 15% in construction costs.
They typically benefit from established utilities and services, which can further shorten investment timelines.
Each type of data centre impacts construction and operational expenses, shaping total investment strategies and financial outcomes.
Geographic Cost Comparisons
Geographic cost comparisons highlight significant variations in data centre construction expenses across different regions, which can heavily influence investment choices.
- United States: The average construction cost for a data centre is approximately £9.5 million per megawatt, translating to about £1,000 per square foot.
- Europe: Costs are notably higher, averaging around £14 million per megawatt and £1,200 per square foot, primarily due to elevated labour and material expenses.
- Asia-Pacific: This region strikes a balance, with costs around £12 million per megawatt, while square footage costs remain similar to those in the U.S.
- Latin America: Here, costs can vary significantly, influenced by local economic factors and infrastructure quality.
Moreover, the geographic location also impacts land costs, which typically make up about 5% of total development expenses.
These variations underscore the importance of strategic planning and thorough analysis when considering relocation options.
Understanding these cost dynamics can greatly aid in making informed decisions for data centre investments.
