Britain should no longer be at the mercy of events abroad, the prime minister argued in a Thursday 9 April op‑ed, calling today’s world “more volatile and dangerous” and tying national resilience to clean, homegrown energy. He backed diplomacy to reopen the Strait of Hormuz while keeping the UK out of offensive operations in Iran. (theguardian.com)

That message landed while he toured the Gulf. On Wednesday 8 April he met Saudi Crown Prince Mohammed bin Salman in Jeddah; later, Downing Street said Sir Keir and US President Donald Trump discussed the need for a “practical plan” to get shipping moving through Hormuz “as quickly as possible”.

The cost‑of‑living link is immediate. With the shipping lane constrained, UK pump prices have climbed: the RAC estimates petrol is up around 10p per litre since the conflict began, pushing the average back above 150p in late March. Diesel has risen further, adding pressure to haulage and food costs. (media.rac.co.uk)

The scale of the choke point explains the squeeze. The International Energy Agency notes Hormuz normally carries close to a fifth of global LNG trade and roughly a quarter of seaborne oil; it also coordinated a record release of 400 million barrels from emergency reserves to blunt the shock. The US Energy Information Administration says Brent averaged about $103 in March and could peak this quarter before easing as supply adjusts. (iea.org)

Starmer’s domestic answer is to speed up clean power that insulates bills from fossil price swings. Britain is moving: wind generated more electricity than gas for the first full year in 2024, and provisional government figures point to renewables supplying about 52.5% of UK power in 2025. Contracts for Difference have restarted momentum-securing 9.6GW in 2024’s AR6 and a record 8.4GW of offshore wind in January 2026’s AR7-alongside the launch of Great British Energy to invest in homegrown generation.

Why this matters for bills: Ofgem says movements in international wholesale gas costs are a primary driver of the price cap; reliance on global gas makes households vulnerable to shocks. More domestic renewables on stable contracts dampen that volatility over time. (ofgem.gov.uk)

But electricity is only part of the story. Heating remains the UK’s weak spot: the English Housing Survey finds around 86% of households rely on gas boilers. Government policy aims for 600,000 heat pump installations a year by 2028, while independent analysis indicates basic insulation can cut household gas demand by up to a fifth-reducing imports faster than new North Sea fields add supply.

For households, the near‑term wins are practical. Check eligibility for the Boiler Upgrade Scheme and local offers; planning changes mean far fewer heat‑pump installs need permission. Top up loft insulation and fix draughts before next winter-simple steps that lower gas use and protect budgets. (moneyweek.com)

Politics remains heated. Conservative figures continue to argue for more North Sea drilling to bolster energy security; Liberal Democrats urge closer European security ties to reduce reliance on a Trump‑led US; Reform UK wants fast‑tracked fossil extraction and to scrap renewable subsidies; and the Greens, led by Zack Polanski, call for ending fossil dependence and strengthening windfall taxes to cap any bill rises.

The immediate test is reopening Hormuz. Oil prices slipped after a ceasefire announcement this week but remain elevated; UN trade analysts warn disruption is already feeding through to energy, food and fertiliser costs. The long‑term fix is clear: build more clean British power and warmer homes so the next shock abroad doesn’t land as a bill at home. (axios.com)
