Slaughter and May and Cravath advise as UK water company targets £800 million capital raise, while a KKR-led consortium's £5 billion bid for an Irish energy business is rejected
Two significant energy and infrastructure transactions emerged on 30 April 2026 with strong UK and Irish nexus. A UK water company — advised by Slaughter and May on the English law side and Cravath in a co-advisory capacity — is targeting an £800 million capital raise, according to Law360. Freshfields advises the underwriting banks on the placement. The transaction structure and specific issuer have not been disclosed in publicly available extracts, but the instruction of two elite firms signals a substantial regulated-infrastructure financing, likely involving a combination of equity and debt instruments. Separately, an Irish energy business has rejected a £5 billion takeover approach from a consortium led by KKR, the US-headquartered private equity and infrastructure firm. The target's board declined the approach, suggesting either a valuation disagreement or concern about regulatory, structural, or strategic fit. At £5 billion, the rejected bid would have represented one of the largest PE-led infrastructure acquisitions in the Irish market. Taken together, the two stories reflect the continued intensity of private capital appetite for regulated infrastructure assets — water utilities and energy networks — driven by their inflation-linked revenue streams and long-duration asset profiles. Infrastructure fundraising by funds such as KKR has accelerated as institutional investors seek real-asset exposure, creating competition for a limited supply of quality regulated targets on both sides of the Irish Sea.
Why this matters
Regulated infrastructure assets — water, energy networks, and utilities — remain among the most actively contested acquisition targets in European private equity because their revenues are index-linked and backstopped by regulatory frameworks such as Ofwat (the UK water regulator) and the Commission for Regulation of Utilities in Ireland. A £800 million capital raise for a UK water company will activate both equity capital markets and leveraged finance teams, alongside regulatory counsel familiar with Ofwat's financing and ring-fencing requirements. The KKR consortium's rejection is equally instructive: it signals that Irish energy boards are not willing to accept opportunistic bids, and the consortium will likely need to return with a higher or differently structured offer — generating further M&A advisory work. Confidence is medium given the Law360 sources are paywalled and only headline-level facts are accessible.
On the Ground
On a regulated infrastructure capital raise, a trainee would summarise regulatory licence conditions relevant to Ofwat's or CRU's ring-fencing requirements, co-ordinate regulatory filing submissions, and assist with grid connection or licence condition review as part of the due diligence workstream.
Interview prep
Soundbite
Regulated infrastructure's inflation-linked revenues make water and energy assets the most contested PE targets in Europe right now.
Question you might get
“If you were advising the board of the Irish energy company that rejected KKR's bid, what factors would you assess in deciding whether to engage with a revised offer?”
Full answer
A UK water company is raising £800 million with Slaughter and May and Cravath advising the company side and Freshfields advising the underwriting banks, while KKR's consortium has had a £5 billion Irish energy bid rejected — two data points on the same day illustrating the intensity of private capital's pursuit of regulated infrastructure. These assets are attractive because their revenues are set by independent regulators and linked to inflation, providing predictable cash flows that service the leverage PE firms use to fund acquisitions. Rejection of the KKR bid doesn't end the story — it typically triggers a revised offer or competing interest, generating sustained advisory work. The broader trend is a structural shortage of quality regulated assets relative to the capital targeting them, which is pushing valuations up and bid timelines longer.
