Living next to a data centre: what UK residents are actually experiencing
Across Britain, roughly 450 large data centres hum away in industrial estates and on the edges of towns. The people living nearby are starting to talk about what that means for their daily lives.
Key points
- The UK has approximately 450 large data centres operating as of 2025.
- Residents near these sites have raised concerns about noise, pollution, and land use.
- Data centres power everyday cloud services like email and video streaming, as well as AI tools.
- A growing debate is forming around the "heat island effect," where facilities raise the local temperature.
A data centre is, at its simplest, a giant warehouse packed with computers. Those computers store your emails, run your streaming services, and now increasingly power artificial intelligence tools like chatbots and image generators. The UK currently hosts around 450 of these large facilities, and they are growing fast.
For most people, data centres are invisible infrastructure. You never see them, you just benefit from them. But if you live nearby, the picture looks very different.
Residents close to these sites have raised a consistent set of complaints. Noise is one. The cooling systems that stop all those computers from overheating run constantly, day and night, producing a low mechanical hum that some neighbours say never stops. Then there is the "heat island effect," a term for what happens when a building pumps out so much heat that it measurably warms the surrounding streets and gardens.
Land use is another flashpoint. Data centres need large, flat plots, often in areas that communities had hoped would become housing or green space. Once a site is built, it tends to stay for decades.
Pollution concerns also surface regularly. Backup diesel generators, kept on standby in case of a power cut, can run during testing and emit fumes. Some facilities sit close to residential streets.
The Guardian AI first flagged the scale of community concern in the UK, and the conversation it prompted points to a gap. The people making planning decisions about where these buildings go and how they operate do not always hear from the people living alongside them.
Why should ordinary people care about this?
Because where these buildings go, and how they are regulated, will shape neighbourhoods for a generation. AI needs enormous amounts of computing power, and that power has to sit somewhere physical. Demand for data centre space is rising sharply across Europe as more businesses and governments adopt AI tools.
If you live near an existing data centre, or near a site earmarked for one, your local planning authority is the first place to look. Planning applications for data centres are public documents, and residents have a legal right to comment on them.
If noise or emissions are already an issue, your local council's environmental health team can investigate. Keeping a dated record of when problems occur, what they sound or smell like, and how long they last gives investigators something concrete to work with.
The broader question of how the UK balances its appetite for AI services against the comfort and wellbeing of the communities hosting the hardware is still very much open.
