Speaking in the House of Lords on 2 September 2026

Debate

Data Centres: Water Resources

Contribution

Proper information about the actual water use of data centres is clearly very important. We are taking action to support the data centre sector in England on this. Part of what we are doing is working across government to determine how we can increase water efficiency, to reduce the data centre water demand in the first place. We are also looking at not just the available evidence but the emerging evidence that is coming through on water use in data centres. One way to get that is to work with Ofwat’s Smart Water Metering Delivery Group, which will look at rolling out smart meters in the non-household market. That will help us better understand what the standards and delivery expectations are and how much water is being used. That work is due to be completed over the next 12 months.
