3 British Nuclear Stocks With Earnings Growth Up To 18%

Oil prices are showing fresh signs of oversupply as high fuel costs curb demand, which keeps attention on alternative power sources that do not rely on crude. For UK investors, that puts listed nuclear power and uranium related businesses in sharper focus as a potential way to gain exposure to long term electricity demand without a direct oil link. This article walks through three UK nuclear energy stocks from the screener that fit that theme.

The three stocks highlighted here offer a compelling starting point if you want exposure to uranium producers, enrichment specialists and reactor operators in the listed market. However, if you want the names that matter most, these 16 nuclear renaissance stocks are the strongest companies we've found.

Rolls-Royce Holdings (LSE:RR.)

Rolls-Royce Holdings is a power and propulsion group whose nuclear link for this screener comes mainly from supplying submarine reactor plants, supported by much larger civil aerospace and power systems activities that shape its overall financial profile.

Rolls-Royce generates £11.8b from Civil Aerospace, £5.5b from Power Systems and £5.0b from Defence, giving a diversified engine and propulsion portfolio, while its market value of about £102.2b reflects the scale of those combined businesses.

For Nuclear Energy Stocks investors, Rolls-Royce matters because it couples that submarine nuclear propulsion expertise with a push into small modular reactors that targets long term, contracted energy demand.

"Rolls-Royce SMR has secured multi-country selections and is already in execution for units in the UK, Sweden and the Czech Republic while aiming to commission up to 2 small modular reactors per year in the mid 2030s and up to 8 per year at maturity, creating a potential new source of high margin revenue and profit growth."

What investors need to watch now is how one unresolved pressure ultimately shapes the profitability that those long duration nuclear projects can deliver.

That unresolved pressure is exactly what the full narrative for Rolls-Royce Holdings unpacks, showing how Rolls-Royce could balance capital intensity with long life nuclear cash flows.

National Atomic Company Kazatomprom JSC (LSE:KAP)

National Atomic Company Kazatomprom JSC is a Kazakhstan based uranium specialist that earns about KZT 1,697b from its Uranium segment and roughly KZT 91b from Ulba Metallurgical Plant, with other activities at about KZT 294b, and a market value near US$16.7b.

Kazatomprom sits close to the fuel side of the Nuclear Energy Stocks theme, supplying mined uranium and related materials that underpin reactor operations worldwide. Uranium focused investors tend to pay attention when long term demand signals start to shift.

"Global structural undersupply of uranium, driven by increasing nuclear build-outs, plant lifespan extensions, and a lag in bringing new projects online, is supporting a multi-year demand upcycle. This is described as positioning Kazatomprom for sustained pricing power and higher sales volumes, which would be positive for revenue and margin growth."

What really matters for Kazatomprom now is how one unresolved pressure on future costs and logistics ultimately filters through to uranium margins.

That cost squeeze is exactly what the full narrative for National Atomic Company Kazatomprom JSC unpacks. It shows how Kazatomprom's uranium position could accelerate or stall if logistics and pricing start to decouple from expectations.

Centrica (LSE:CNA)

Centrica is an integrated energy group that supplies power and related services to homes and businesses, with nuclear generation forming part of its broader low carbon portfolio alongside trading and infrastructure activities.

Centrica earns about £16.3b from Retail, £6.0b from Optimisation and £1.6b from Infrastructure, although its nuclear generation sits within this wider mix rather than dominating it, and the group’s market value is around £6.9b.

Centrica provides exposure to nuclear-linked power production within a much larger energy services and infrastructure platform, which may appeal to investors who want nuclear in their mix without focusing solely on a pure uranium or reactor specialist.

"Expanding investment in regulated and contracted infrastructure such as Sizewell C, Grain LNG and the Meter Asset Provider, which together contributed about £80m of EBITDA in H1 2026 and are expected to reach roughly £175m in 2026, would represent a larger base of long-duration earnings and a higher share of EBITDA from predictable sources."

The key consideration for Centrica’s nuclear role is how any single, less-visible pressure on cash-backed earnings might influence the extent of its margins.

If that earnings pressure matters to you, read the full narrative for Centrica to see whether Centrica’s nuclear exposure is quietly accelerating cash generation or masking future strain.
