Scotland’s planning system has rarely had to grapple with a new development sector growing at the pace now being seen with data centres. Over the last 12 months, proposals have emerged across the country for facilities ranging from tens to hundreds of megawatts, often linked to AI, cloud computing and digital infrastructure. The scale of some of these proposals has prompted questions not only about land use planning, but also about energy policy, grid capacity, water resources and the extent to which Scotland should actively encourage this emerging sector.
In recent weeks, the Scottish Government has taken a series of significant planning interventions that signal a clear shift in its approach. Two new Ministerial Directions and a high-profile Scottish Parliament debate suggest that data centres are rapidly becoming a matter of national planning importance.
Increased Ministerial oversight
The first significant step came in August when Scottish Ministers introduced the Town and Country Planning (Notification of Applications) (Data Centres exceeding 50MW Power Capacity) (Scotland) Direction 2026. This direction requires planning authorities to notify Scottish Ministers within seven days of validating any planning application for a data centre exceeding 50MW of power capacity. The requirement applies both to new applications and those already under consideration.
The direction is very similar to that issued in September 2025 in respect of planning applications for 10 or more houses. So far that direction hasn’t resulted in the call-in of any housing applications for determination by the Scottish Ministers and so it might be argued that the data centre direction is a relatively modest procedural change, however it is a clear indication that the Scottish Government wants strategic oversight of a development pipeline which, in its opinion, could have implications for Scotland's energy infrastructure and climate ambitions.
The accompanying ministerial statements repeatedly emphasise balancing economic opportunity with energy demand, climate objectives, community wealth building and impacts on local communities suggesting that Ministers are already thinking beyond traditional planning considerations and towards wider questions of national policy.
Mandatory EIA for major data centres
The second and arguably more significant intervention, certainly for developers, occurred on 16 September when Scottish Ministers issued a further direction which effectively makes Environmental Impact Assessment mandatory for data centres exceeding 50MW where they fall within the relevant Schedule 2 development categories.
The Public Finance Minister, Hannah Mary Goodlad, who has portfolio responsibility for planning, justified the move by highlighting the potential impacts of large-scale data centre developments on landscape, biodiversity, water resources, noise and energy infrastructure.
Many data centre developers had already been anticipating extensive environmental assessment and the direction removes much of the uncertainty around screening for larger schemes, but it will increase not only the time involved in preparing planning applications and a developer’s upfront costs, but also the time taken to determine planning applications. Environmental considerations which may previously have sat at the margins of some applications will now move to centre stage.
The Parliament debate: no moratorium, but not quite business as usual
Ahead of the Scottish Government announcing the notification direction, there was a Scottish Parliament debate on hyperscale data centres, initiated following calls from the Scottish Greens for a moratorium on major data centre developments pending the preparation of a national strategy and planning guidance. Concerns raised included the cumulative impact on electricity demand, pressure on water resources and the broader environmental consequences of hosting large AI-driven facilities.
The Scottish Government rejected the calls for a formal moratorium with the Public Finance Minister arguing that such an approach would send the wrong message to investors and would be inappropriate given Scotland's ambition to attract technology investment.
The debate ultimately produced broad political support for the preparation of national planning and spatial guidance, with Ministers committing to further work and reporting before the end of the year. There was also strong cross-party recognition that decisions on data centres cannot simply be treated as a series of isolated local planning applications.
What does this mean for developers?
The direction of travel is therefore unmistakable. Scotland is moving towards a more strategic, nationally coordinated framework for determining data centre proposals.
Three key points stand out.
1. Energy will become the critical planning issue
Historically, data centre planning applications often focused on matters such as traffic, design, landscaping and noise. While those issues remain important, future debates are likely to be dominated by energy.
Developers should expect increasing scrutiny of power demand, grid connections, renewable energy sourcing, heat recovery proposals and wider system impacts as the Scottish Government links planning decisions to broader climate and energy objectives.
Projects that can demonstrate a credible contribution to Scotland's net zero ambitions are likely to be better placed than those perceived simply as large consumers of electricity.
2. The cumulative effects argument is gaining traction
One striking feature of the Parliamentary debate was the repeated focus on cumulative impacts rather than individual projects. Critics have pointed to the scale of the national pipeline of data centre applications and argued that individual applications cannot be considered in isolation.
So even where a particular development is acceptable on its own merits, decision-makers may increasingly ask how it fits within the wider picture of national demand for power, water and infrastructure. Developers should therefore be prepared to explain not only what their project does, but why it contributes positively to Scotland's overall digital and economic strategy.
3. National policy is coming
Perhaps the most important takeaway is that while Scotland does not yet have a settled planning policy framework for data centres, one is on its way.
The recent directions, the recall of the planning appeal relating to a proposed Edinburgh data centre, and Ministers' commitments during the Parliamentary debate all point towards the emergence of national guidance over the coming months, with the Minister committing to coming back to Parliament before Christmas “with guidelines that will give business and communities confidence”.
For developers, that creates both risk and opportunity. The risk is obvious: projects currently progressing may find themselves caught by evolving expectations and increased scrutiny. The opportunity is that Scotland remains keen to attract investment in digital infrastructure and the Government has explicitly rejected calls for a blanket ban or moratorium.
Looking ahead
The consistent message from Ministers is that Scotland still wants to capture the economic opportunities associated with AI and digital infrastructure, but the recent Ministerial directions, the appeal recall and the Parliamentary debate all demonstrate that data centres are no longer being viewed as just another employment use. They are increasingly being treated as nationally significant infrastructure with potentially profound implications for Scotland's energy system, climate objectives and communities.
The projects most likely to succeed will therefore be those that can demonstrate not only planning compliance, but a convincing answer to the much broader question: why is this data centre good for Scotland?
