Heating oil refunds are landing. The bigger problem is oil has no cap at all.

Energy bills · Buzz Money Coach reacts · 1 September 2026

Reacting to the Competition and Markets Authority press release “CMA secures compensation for heating oil customers”, published on 28 August 2026, and to MoneySavingExpert’s report of it the same day, which also confirmed the opening date of Northern Ireland’s heating oil support scheme. Every price, threshold and date below is read from the CMA case file, GOV.UK, nidirect, the House of Commons Library and the Office for National Statistics, with the arithmetic shown.

The refund is right. It is also a plaster on a broken leg.

Here is what we think, before any of the detail. The CMA has done a genuinely good thing for a small number of people, and the headlines will treat it as the story. It isn’t. Roughly 1,700 households getting somewhere between £150 and £350 back is a fair remedy for a specific act — suppliers cancelling confirmed orders and re-offering the same oil at a much higher price. But the reason that was possible, and the reason it will be possible again, is that home heating oil sits entirely outside the regulated energy market. There is no price cap on it. There is no standing charge to argue about, no Ofgem tariff comparison, and no monthly direct debit quietly smoothing a winter’s heating across twelve payments. You order a tank, and whatever the market says that morning is what you pay, in one lump, in advance.

That is the actual coaching problem, and it belongs to far more than 1,700 people. The House of Commons Library’s briefing Households off the gas-grid and prices for alternative fuels puts an estimated 4.8 million households in Great Britain off the gas grid in 2024 — 16.0% of domestic properties. Heating oil is the sole heating source for 3.5% of households in England and Wales and 5.1% in Scotland. In Northern Ireland it is 49.5% — about half of every home in the country. None of them are covered by the price cap, and the same briefing notes that heating a typical three-bedroom house costs around 50% more on heating oil than on mains gas.

What actually happened

The CMA opened a consumer protection review in March 2026 after the Israel/US–Iran conflict disrupted crude oil transit through the Strait of Hormuz, the route for roughly a quarter of the world’s seaborne oil. Heating oil prices almost doubled inside a single month, with typical mid-month prices reaching 104 pence per litre in March and April 2026 — higher than the previous peak in June 2022, according to the Commons Library briefing Government support for the cost of heating oil.

In the middle of that, some suppliers cancelled orders customers had already placed and confirmed, mostly through intermediary comparison sites, then offered the same delivery at the new, much higher price. The CMA’s view was that this may have been a breach of contract. Suppliers under review have now agreed to compensate. Sarah Cardell, the CMA’s Chief Executive, described heating oil as “a necessity that many people rely on”.

The practical shape of the scheme, from the CMA’s case page and MoneySavingExpert’s reporting:

• You do not need to apply. The CMA states eligible customers “either have been, or will be, contacted directly”. Around 800 people had been contacted by 28 August, by email or phone.
• Two remedies. If you bought replacement oil at the higher price, you get the difference back. If you never rebought, your original order is honoured at the price you originally agreed.
• Keep your paperwork. Claims for a replacement purchase need evidence — receipts and delivery notes.
• LPG is excluded, MoneySavingExpert reports, despite similar complaints about price rises.
• The CMA has not named the suppliers taking part. That matters practically: there is no list to check yourself against.

What the spike actually did to a household

This is where the numbers stop being abstract. A 900-litre delivery is a common order size, and it is what the Consumer Council for Northern Ireland surveys alongside 300 and 500 litres.

The gap nobody legislated away

Compare that with a mains-gas household on the price cap. From 1 October 2026 Ofgem’s cap sets a typical direct debit bill at £1,723 a year, and we worked through what that means in our piece on the October cap. Two protections come attached to it: a regulated ceiling on the unit rate, and the ordinary practice of paying monthly, so October’s heating is partly paid for in June.

The oil household gets neither. Not a lower ceiling — no ceiling. And no smoothing at all unless it builds the smoothing itself. That is the single most useful thing an off-grid household can do, and almost nobody does it.

Northern Ireland: £100, and applications open on 9 September

Half of Northern Ireland heats with oil, and the scheme confirmed alongside the CMA news is the most concrete thing in this article. From nidirect:

• £100 per household, as a pre-paid virtual voucher redeemable at oil suppliers. Around 340,000 households are expected to be eligible.
• Applications open Wednesday 9 September 2026 and close 31 March 2027.
• You must use home heating oil as your main heating source, and have been a Northern Ireland resident during a qualifying period. The qualifying periods are 1–30 April 2026 and 1–30 November 2026.
• You also need either a qualifying benefit — Pension Credit, Universal Credit, income-related ESA, DLA, PIP, Attendance Allowance, Armed Forces Independence Payment, or the Constant Attendance Allowance elements of Industrial Injuries Disablement Benefit or the War Pension Scheme — or a net annual income below £30,000 as a single person or couple, including pensioners, after tax, National Insurance and pension contributions.
• It does not affect your benefits and does not count as income on a Self Assessment return.
• Helpline 0800 072 0266 from 9 September, or ask at any Jobs and Benefits office.

Two things worth saying plainly about that £100. First, at today’s 87.69p it buys about 114 litres — roughly an eighth of a 900-litre tank. It is help, not a solution, and anyone budgeting on the assumption it covers a winter will be short. Second, the November qualifying window is the one to diarise. If your income or benefit position changes between now and then — hours cut, a benefit awarded, a partner stopping work — you may qualify on the November period even if you didn’t on the April one. Applications stay open until 31 March 2027, so there is time to re-check in December.

Great Britain: the money exists, but you have to go and ask

England, Scotland and Wales got their share of the same package. On 16 March 2026 the government announced £53 million for low-income heating oil households — £27 million to England, £17 million to Northern Ireland, £4.6 million to Scotland and £3.8 million to Wales. Unlike the Northern Ireland voucher, none of it arrives automatically, and there is no national application form. It went into existing crisis funds:

• England: local councils, through the Crisis and Resilience Fund, which took effect on 1 April 2026 and was topped up specifically for oil-heated areas. Find yours at gov.uk/find-local-council and ask for the Crisis and Resilience Fund by name.
• Wales: the Discretionary Assistance Fund.
• Scotland: the Scottish Welfare Fund, applied for through your council.

Discretionary funds get spent. The households that get help are the ones that ask early in the financial year, not the ones that ask in February when the pot is empty.

The deadline in three weeks that has nothing to do with oil

While you are looking at winter heating, there is a date coming that catches people out every year and is not oil-specific at all. The Winter Fuel Payment qualifying week for winter 2026 to 2027 is 21 to 27 September 2026. You qualify if you were born on or before 27 June 1960 and live in England or Wales. It is usually paid automatically in November or December, and it is worth between £100 and £300 — £200 if you live alone and were born between 28 September 1946 and 27 June 1960, £300 if you were born before 28 September 1946. If your individual income is over £35,000, HMRC takes it back. Check your position at gov.uk/winter-fuel-payment. In Scotland the equivalent is the Pension Age Winter Heating Payment, worth between £105.55 and £316.70, with confirmation letters going out from November 2026.

What to do this week

1. If you had a heating oil order cancelled between roughly March and June 2026, dig out the paperwork now. The confirmation email for the cancelled order, the invoice for whatever you bought instead, and the delivery note. The CMA says suppliers will contact you, but it will not name which ones joined the scheme, so if nothing arrives in the next few weeks, ring your supplier and quote the CMA’s heating oil consumer protection case. The CMA’s general enquiries address is on its case page.
2. Set up the oil fund. Twenty minutes: total your litres for the last year, multiply by today’s price, divide by twelve, standing order on payday into a separate pot. Our survival budget calculator will show you what is genuinely available to commit, and cut your bills covers where to find it if the answer is nothing.
3. Northern Ireland: put 9 September in the diary, and December too, for the November qualifying window.
4. Great Britain: phone your council this week, not in January.
5. Anyone born on or before 27 June 1960: check the Winter Fuel Payment before the 21–27 September qualifying week, and see whether the Warm Home Discount applies to your electricity account — off-grid households are often eligible and often assume they are not.

If filling the tank this winter is genuinely out of reach, or last winter’s went on a credit card that is still there, deal with that first and separately. MoneyHelper, StepChange and National Debtline give free, independent debt help, today, before anything else on this list. We coach; we do not advise on debt, and those three do it properly and for nothing.

What is still uncertain

Three honest gaps. First, the CMA case is open, not closed — it was formally opened on 27 August 2026, and press reporting suggests not every supplier has signed up. The case page is where any enforcement action will appear. Second, nobody is publishing an official UK heating oil price any more: the ONS series we used above stops at January 2025, so the only current figures come from commercial suppliers and comparison sites, and the Consumer Council’s survey covers Northern Ireland only. For a fuel that half of Northern Ireland and 4.8 million off-grid homes depend on, that is a real hole in the public statistics. Third, the £53 million was a one-off response to one spike. Nothing announced so far makes heating oil a capped or regulated product, and no further support has been confirmed for winter 2027. The next scheduled thing anyone can rely on is the Ofgem cap changing again for the quarter starting 1 January 2027 — which, if you heat with oil, will not apply to you.

Which is the whole point. When the protection isn’t coming, the household has to be the protection. £65.77 a month into an account marked “Oil” is not exciting, and it is the difference between a tank being an expense and a tank being an emergency. If you want the same treatment applied to every other lumpy bill you are quietly dreading — the car, the insurance renewal, Christmas — that is what building a fund that actually holds is for.
