Recognition of data centres among UK consumers has climbed, according to research commissioned by Telehouse, yet this increased familiarity has not bolstered public confidence in the sector. A Censuswide poll of 2,000 British adults revealed that 52% now know what a data centre is, compared with 40% in 2024. Despite this gain, nearly three-fifths of respondents admitted they remain uncertain about the facilities' function or purpose.
The picture darkens when examining attitudes toward infrastructure impact. The share of respondents who view data centres as benefiting their digital services fell to 37% this year from 48% in 2024. Simultaneously, those perceiving a negative effect jumped from 4% to 15%, signalling a troubling reversal in public sentiment even as awareness spreads.
Energy Concerns Rise Alongside Awareness
Environmental and power-related worries have emerged as the primary driver of shifting opinion. Fifty-six percent of survey participants expressed concern about data centre energy consumption, up from 45% the previous year. Separately, 55% judged the environmental footprint of these facilities to be substantial.
Telehouse initiated this tracking study in 2024, before the UK Government granted data centres Critical National Infrastructure status. The company attributed heightened public and political focus on the sector to this CNI designation, major construction projects, and the explosive growth of AI systems demanding vast computational resources.
The survey does not pinpoint whether AI expansion or heightened visibility directly caused the shift in public views. It does, however, demonstrate that growing recognition has coincided with mounting anxiety over energy use and environmental consequences.
Awareness is an important first step, but these findings show it does not always translate into confidence
Mark Pestridge, Executive Vice President and General Manager at Telehouse Europe
Pestridge noted that the public seeks clarity on how digital services operate, data handling practices, and industry efforts to tackle energy and sustainability challenges. He added that operators must narrow this understanding gap through collaboration, openness, community engagement and clearer communication of the value data centres deliver.
Community Engagement Is Becoming an Operator Issue
The survey's implications extend beyond general public awareness into local politics. Fifty-seven percent of respondents wanted either local councils or national authorities to lead consultations with communities before data centre projects proceed.
One quarter of those surveyed reported being personally affected by a data centre development near their residence. Among this group, 37% cited environmental impact as their primary concern, outweighing worries about property values, traffic, or noise.
Not all findings were discouraging. Telehouse noted that more respondents expressed comfort than discomfort at the prospect of a facility opening nearby. Additionally, 30% of those already affected by a development said it had delivered jobs or investment to their locality.
This mixed picture presents operators with a layered challenge. As data centre projects gain visibility, communities are likely to demand details about environmental and local effects alongside explanations of the digital services these installations enable.
CNI Status Has Not Closed the Understanding Gap
Two years have passed since the UK Government designated data centres as Critical National Infrastructure, acknowledging their importance to essential services and economic activity. This formal recognition elevated the sector's standing in the nation's infrastructure hierarchy. Yet Telehouse's latest findings show a majority of respondents still struggling to grasp what data centres are or how they function.
Artificial intelligence adds fresh complexity to the picture. As AI systems become woven into daily work and personal routines, the computing power required to run them is drawing increased scrutiny. Telehouse has contended that this moment demands clearer industry communication about the link between routine digital activity and the physical infrastructure underpinning it.
The survey's findings on shifting sentiment suggest that messaging must also tackle the concerns accompanying this expansion. For operators, the task goes beyond describing data centre operations. Energy consumption, environmental footprint, and community consultation practices are now integral to how the sector is perceived.
Greater Visibility Brings a Higher Burden of Explanation
Telehouse's two-year comparison reveals a striking paradox. More people recognise the data centre label, yet fewer believe these facilities benefit their digital experience. Energy consumption anxiety has also intensified.
The research does not explain the causes behind this attitude shift, nor does a single industry-funded study capture the full spectrum of UK public opinion on data centre expansion. It does, however, suggest that rising awareness alone will not guarantee public acceptance.
As the sector expands to serve cloud services, AI, and emerging digital applications, operators must prioritise public engagement. Describing internal data centre operations is no longer sufficient. Operators must articulate local contributions, explain environmental management strategies, and clarify how communities will participate in project development.
