Downing Street is set to outline targeted support for households reliant on heating oil on Monday, after crude’s surge pushed upfront refill costs sharply higher. Brent has traded back above $100 a barrel since the Iran war disrupted flows through the Strait of Hormuz, with intraday spikes close to $120 last week and prices hovering near $106 early Monday, according to Axios and AP. The Prime Minister is also expected to warn firms against exploiting the crisis. (axios.com)

Heating oil sits outside Ofgem’s price cap, so off‑grid homes feel market moves first. Around 1.7 million UK households use heating oil, with the issue most acute in Northern Ireland where roughly 62.5% of homes rely on it. In England and Wales, Census 2021 data show about 3.5% of households use oil as their only central heating; in Scotland, it is around 6% on Scottish Government figures. (gov.uk)

Recent price snapshots illustrate the squeeze. MoneyWeek reports average quoted prices leapt from about 60p per litre on 28 February to more than £1.30 by 9 March - a rise of roughly 120%. In Northern Ireland, the Consumer Council’s tracker cited by the Irish News showed the average cost of 500 litres climbing to just above £434 in early March, up 41% week‑on‑week. Customers have also reported cancelled orders and re‑quotes at higher prices. (moneyweek.com)

The Chancellor, Rachel Reeves, said over the weekend she had ‘found the money’ to help, and last week asked the Competition and Markets Authority to examine complaints of price gouging in heating oil. CMA chief executive Sarah Cardell said the watchdog is moving quickly and will not hesitate to enforce if breaches are found. Industry body UKIFDA, which represents distributors, says members are seeing very high demand and are honouring deliveries as swiftly as possible. (gov.uk)

Expect the package to be narrowly targeted - media reporting has suggested a modest fund in the tens of millions - alongside a tougher line on unfair practices. During a visit to Belfast last week, the Prime Minister said the government ‘will act’ against unjustified price hikes, reflecting concerns in a region where oil is the dominant heating fuel. Any legal action would hinge on CMA findings and existing consumer law. (irishtimes.com)

For households on mains gas and electricity, Ofgem has already confirmed the default tariff cap will fall by 7% for 1 April–30 June 2026. The next reset, covering July–September, will be announced by late May and will be shaped by wholesale prices over the spring observation window - meaning prolonged energy market stress could reverse some of April’s relief. Ofgem and Cornwall Insight outline the timetable and mechanics. (ofgem.gov.uk)

This is not just a household story. SMEs that heat depots, workshops or rural sites with oil are seeing working capital tied up in larger‑than‑usual orders. In Northern Ireland, for example, the average cost of 900 litres rose from roughly £537 on 26 February to about £948 by 5 March, according to the Irish Times - a near‑£400 swing in little more than a week. For sole traders and contractors, that is real cashflow. (irishtimes.com)

What can consumers do while waiting for policy detail? In practical terms, speak to more than one distributor, ask for a fixed price at order confirmation, and check cancellation terms. Oil‑buying clubs can improve local bargaining power and smooth deliveries; the Consumer Council in Northern Ireland publishes a weekly price checker and signposts to club schemes. Keep dated order confirmations and receipts, as these help if you later raise issues with a supplier or the CMA. (consumercouncil.org.uk)

Market‑wise, the moving parts to watch this week are straightforward: the scope of Monday’s announcement, any early CMA updates, and whether shipping through Hormuz remains constrained. Each will feed into wholesale products and, with a lag, into July’s cap forecasts for mains‑connected homes. For oil‑heated households, however, relief hinges on both global supply routes and how quickly aid lands locally. (apnews.com)
