How Water Utilities Are Sidestepping Bonus Caps – Regulatory Gaps and Market Implications

The ban on bonuses in the water sector has ignited a new compensation wheel that lifts executives' total pay packages.

Regulatory Loophole: The Water (Special Measures) Act 2025 Gap

In England and Wales, the water regulator Ofwat can only wield powers explicitly granted by Parliament; it can block performance‑related bonuses but cannot curb other forms of remuneration.

Executives' Pay Playbook: What Replaces the Banned Bonus

■Salary hikes, allowance awards, and retention payments are being used to sidestep the bonus prohibition.

■Annual reports show a 1.5% rise in total executive packages, reaching £25.3m across CEOs and CFOs.

■This upward trend persisted for the second consecutive year despite the ban.

Thames Water’s Surprising £1m Payout

Thames Water’s CFO Steve Buck earned a £591,000 salary for the fiscal year ending March, yet received a delayed £1m signing fee in July – a classic example of a “work‑around” payment emerging from the bonus restriction.

Market and Public Trust Ripple Effects

■A government spokesperson called the payout "unacceptable" for a poorly performing water utility, attempting to soothe public outcry.

■Ofwat’s recent comments stress that opaque remuneration decisions erode customer confidence.

■The regulator’s upcoming autumn review leaves uncertainty over whether stricter rules will be imposed.

Markets are questioning the durability of such governance gaps; investors may see a rise in water utilities' cost of equity as regulatory risk climbs. This could trigger a repricing pressure on infrastructure funds that traditionally rely on stable dividend yields.
