Chancellor Rachel Reeves has signalled targeted support for households reliant on heating oil after sharp price rises linked to the conflict in Iran. In statements to MPs on 9–10 March, she said oil‑heated homes face “unique challenges”, asked the Financial Secretary to convene rural and Northern Irish MPs to explore options, and pressed the Competition and Markets Authority (CMA) to remain vigilant across heating‑oil and road‑fuel pricing. She also said she would meet forecourt operators and would not hesitate to call out retailers that fail to provide data to the new Fuel Finder scheme. (hansard.parliament.uk)
Heating oil sits outside Ofgem’s price cap and is highly exposed to crude and jet‑fuel markets. Around 1.5 million UK homes rely on it, predominantly in rural areas. On 11 March the CMA said it had heard “troubling reports” of cancelled orders and sudden price increases and is examining the market. Reporting has also documented delivery cancellations and steep price jumps in recent days. (gov.uk)
For on‑grid customers, Ofgem’s default tariff cap will fall by around 7% to £1,641 for a typical‑use dual‑fuel household from 1 April to 30 June 2026. Ofgem has also confirmed technical adjustments from April, including moving Warm Home Discount costs from the standing charge to the unit rate. (ofgem.gov.uk)
Treasury policy changes announced at Budget 2025-funding 75% of the Renewables Obligation from 2026–27 and ending the Energy Company Obligation-are due to remove about £150 from average bills from April. Even with this adjustment, bills remain above pre‑crisis levels in real terms compared with Q2 2021. (gov.uk)
Analysts warn that wholesale volatility could lift the cap again in the summer. Cornwall Insight now projects a July rise of roughly 10% to around £1,801, though Ofgem will confirm the Q3 level by late May based on observed market data. (uk.finance.yahoo.com)
Competition oversight is tightening. In December 2025 the CMA reported that pump‑price margins remained “persistently high” relative to 2015–2019 benchmarks. Reeves has told MPs she will not tolerate firms exploiting the crisis and has asked the CMA to scrutinise both heating oil and motor fuels while the Fuel Finder data‑sharing tool is rolled out, with most retailers already signed up according to the Chancellor.

Industry groups dispute suggestions of profiteering. The Petrol Retailers Association says forecourts operate on thin margins and, in a recent letter, criticised what it called “inflammatory” ministerial language while continuing to engage with government on data sharing for Fuel Finder.

Fuel duty policy remains sensitive. Budget 2025 extended the temporary 5p cut until 31 August 2026 and set a staged reversal from September 2026 back to March 2022 rates by March 2027. With oil‑market pressures elevated, the Prime Minister has said the planned rise is under review; Reeves said on 11 March it was too soon to freeze duty again and that enforcement against unfair pricing would be prioritised.

Political pressure is growing. Conservative leader Kemi Badenoch has urged the Government to scrap September’s duty increase and to “get Britain drilling again” in the North Sea-positions she set out during visits to Aberdeen earlier this year. (pressandjournal.co.uk)
What to expect next: off‑grid homes could see targeted relief if ministers replicate or adapt the 2023 Alternative Fuel Payment, which provided a £200 one‑off grant to heating‑oil users. For on‑grid customers, the April cap reduction offers near‑term relief, but Q3 will depend on wholesale prices. Live CMA work on heating oil and ongoing Treasury engagement suggest further decisions within weeks. (gov.uk)
