Private Capital, Public Outcomes: What EQT’s move tells us about the future of UK water

The UK water sector is at a crossroads. Investment needs are skyrocketing, public trust is fragile, and the expectations for environmental performance have never been higher.

In that context, EQT’s acquisition of a 42% stake in Kelda Holdings, Yorkshire Water’s (YW) parent, is more than a company specific event. It’s a clear market signal that long duration investors still believe the UK water sector has a strong future.

This piece looks at what that signal means in practice, and how companies can position themselves to attract capital and deliver against rising expectations.

Why investors still want in

The sector delivered £9.2bn of investment in 2023-24, the highest annual figure since privatisation. That alone hould tell us something. 

The challenge is that companies can’t continue at this pace on existing balance sheets. They need new equity, stable capital structures and long term partners.

That’s why it matters that major investors like EQT, GIC and TCorp increased their stakes through this recent deal. It reinforces the view that water remains a “long term essentials” sector with predictable revenue streams, even amid scrutiny.

Regulation is shifting (and in the right direction)

The Cunliffe Review has already helped create a more constructive backdrop heading into AMP8. It’s nudging the sector towards greater financial resilience and transparency, which are exactly the conditions pension funds and long term investors need to re enter the market. 

The upcoming White Paper will likely harden that direction.

The takeaway… Policy is slowly aligning with the investment the sector needs.

The model still works, but it does need recalibrating

Since privatisation, the industry has seen over £236bn of private investment, delivering infrastructure upgrades that would otherwise have stalled. But, future environmental and resilience requirements dwarf what came before. The model isn’t broken, but it is under strain.

The answer isn’t “more debt.” It’s “better matched capital.”

What companies need to focus on

In my view, there are four imperatives:

1. Strengthen balance sheets: Some companies will need equity injections before AMP8 can be delivered credibly.
2. Prove delivery capability: Investors want confidence, not just ambition.
3. Invest in people and digital systems: Capability gaps will limit outcomes more than capital gaps.
4. Repair trust through transparency: Financial & environmental openness is becoming a precondition for investment.

These are exactly the areas where BFY supports clients: translating strategy into operational and customer ready results.

The direction of travel is becoming clearer

EQT’s investment doesn’t solve the sector’s challenges. But it proves that strong, long term capital is not only available; it’s actively looking for opportunities.

The companies that present credible plans, demonstrate real delivery, and embrace transformation will attract that capital first.

In practice, the real challenge isn’t setting the ambition, it’s translating that investment into consistent, operational outcomes. That’s where many organisations will succeed or struggle over the coming years.

At BFY, we typically work with water companies at exactly this point. Helping turn large-scale investment programmes into tangible performance improvements, whether through reshaping operating models, improving performance visibility, or enabling teams to respond to rising operational and customer demand.

For example, we recently supported a water company following a major platform investment where the expected benefits weren’t being fully realised. By aligning the operating model, planning processes, and ways of working with the new capability, we identified around 30% efficiency improvement. The technology was already in place, but the organisation needed to evolve to unlock its value.

For a sector facing the most demanding investment era since 1989, that’s the difference that will matter. And it’s an opportunity worth grabbing.
