3 UK Utility Stocks With More Predictable Cash Flows Right Now

Simply Wall St·09/16/2026 09:22:08
Listen to the news

Inflation back above 3%, oil near $108 and government bond yields at multi decade highs have pushed UK utilities and power generators into the spotlight. Some shares exposed to these pressures may see squeezed budgets and choppy sentiment, while others with steadier contracts or regulated income could appear relatively sheltered. This article explains the backdrop, then outlines three UK regulated utilities and power generators that may be well positioned in the face of this latest rise in costs and rates.

The three UK utilities featured below are only a starter set, since the broader screen surfaced 7 more listed operators and generators with equally compelling stories that are not covered in this article. To see the full line up and quickly identify which regulated or contract driven businesses best fit your own thesis, head straight into the UK Regulated Utilities and Power Generators screener.

National Grid (LSE:NG.)

National Grid gives this screener direct exposure to the pipes and wires of the UK energy system, with much of its income shaped by regulated frameworks that are designed to keep cash flows relatively steady even when inflation and fuel costs jump around.

National Grid transmits and distributes electricity and gas across the UK and US, with UK Electricity Transmission at £2.9b, UK Electricity Distribution at £1.9b, New England at £4.2b, New York at £7.6b and National Grid Ventures at £1.1b in revenue, and a market value of about £55.2b.

"National Grid plans to invest around £60 billion in its networks over the next 5 years, which is expected to drive significant asset growth and provide strong visibility on future revenues."

What really moves the dial for investors is how one less visible pressure shapes the balance between those future earnings and the cost of funding them.

That funding tension is exactly what the full narrative for National Grid unpacks, showing where regulation, capex and balance sheet pressures could be masking opportunity for National Grid.

Drax Group (LSE:DRX)

Drax Group is one of the clearest plays on the screener’s theme, supplying renewable and flexible power into the UK grid while leaning heavily on contracts and long term support mechanisms that can help anchor cash flows when fuel prices and inflation swing around.

Drax Group runs biomass and flexible generation assets plus an energy supply arm, with Biomass Generation at £4.1b, Energy Solutions at £2.4b, Pellet Production at £849 million and Flexible Generation at £204 million in revenue, and a market value of about £2.7b.

"The recent agreement on a government-backed low-carbon dispatchable CfD for Drax Power Station (covering all units through 2031) significantly increases long-term revenue visibility and reduces earnings volatility, supporting stable EBITDA and predictable cash flows well into the next decade."

What really matters next is how one unresolved pressure shapes the gap between those contracted cash flows and the returns equity investors actually receive.

That gap is exactly where the story gets interesting, and the full narrative for Drax Group shows how Drax Group’s contracts, capital plans and policy risks could be accelerating or stalling equity returns.

Centrica (LSE:CNA)

Centrica plugs straight into the UK Regulated Utilities and Power Generators theme, combining British Gas supply with power generation, energy trading and infrastructure like storage and solar, with most of its £16.3b top line coming from Retail and a market value of roughly £6.7b.

Centrica gives this theme a different flavour, because it links regulated and contract driven power assets with a very large retail base that feels wholesale price moves in real time.

"Centrica's expanding investment in regulated, low‑carbon generation assets (notably the Sizewell C nuclear project), combined with opportunities in potential nuclear life extensions and carbon storage (Morecambe Net Zero), positions the company to capture stable, long‑duration, inflation‑linked returns amid accelerating decarbonisation policies, supporting predictable revenue and enhanced margins over the long term."

What really decides how attractive that story looks is how one still unresolved policy choice shapes the balance between future returns and risk.

That unresolved policy piece is exactly what the full narrative for Centrica tackles, highlighting where accelerating decarbonisation could be masking upside or stalling returns for Centrica holders.
