Smart meters, stronger oversight: What the water sector shake-up means for customer operations

---

The UK water sector is entering a new era. And it’s not just policy-level changes that are making waves. Real, measurable impact is already visible on the ground:

• Over 2.6 million smart meters have been deployed across England and Wales, with Thames Water accounting for 1 million+ in the London area alone.(1)
• Aggregate water savings now exceed 75 million litres per day, and this figure is expected to grow as rollouts accelerate toward tens of millions of meters by 2030.(2)
• Households with smart meters have reduced usage by 12–17%, delivering both conservation gains and cost savings.(3)
• Research by Waterwise and Arqiva (commissioned by Frontier Economics and Artesia) estimates that sustained rollouts of ~1 million meters per year could generate £1.9 billion in net societal benefit.
• Full-scale smart meter deployment is expected to yield £4.4 billion in public benefit against a £2.5 billion cost, equating to £1.70–£1.80 of benefit per £1 invested.(4)

This is not just a technological update. It is both environmentally and strategically necessary. These numbers demonstrate why smart metering is central to the biggest regulatory change in decades.

Utilities and their operational partners face both complex challenges and previously unheard-of opportunities as the government gets ready to eliminate Ofwat and implement extensive reforms. The stakes couldn't be higher—and neither could the potential rewards.
