Heating oil, your Norfolk supplier, and your rights: what the CMA said in September 2026
The Competition and Markets Authority put every heating oil supplier on notice in September 2026 over unfair contract terms. For Norfolk's oil-heated households, here is what changed and what to do if your order goes wrong.
On 10 September 2026 the Competition and Markets Authority wrote an open letter to domestic heating oil suppliers, reminding them that the terms and conditions they put in front of customers must be fair under the Consumer Rights Act 2015. The letter followed months of CMA work into what happened to householders whose orders were cancelled during the price surge triggered by conflict in the Middle East. In parts of Norfolk where nearly every rural home runs on kerosene from a tank in the garden, this is not a background regulatory story. It is a set of rights the supplier at the other end of the phone now knows the regulator is watching.
This piece explains what the CMA said, why the letter matters more in Norfolk than in most counties, and what a household with an oil tank should actually do the next time an order goes wrong. It is a companion to our Norfolk oil heating buyer’s guide, which covers prices, tanks and switching. This one covers what happens when the supplier stops answering the phone.
What the CMA letter actually says
The CMA’s letter, published on gov.uk on 10 September 2026, is directed at every business selling heating oil to consumers in the UK. It is not new law. It is the regulator putting suppliers on formal notice that the existing law applies to them and that their standard terms will be read against it.
The specific concern, in the CMA’s own wording, is contract terms that “seek to remove or reduce a supplier’s liability to consumers, including where the supplier fails to perform its contractual obligations or there is a delay”. In practice that means clauses tucked into the small print saying the supplier is not responsible if the tanker does not arrive, if the order is cancelled after payment, or if delivery is delayed by weeks. Under Part 2 of the Consumer Rights Act 2015, terms of that kind are unfair and cannot be enforced against a consumer. A supplier that relies on them is likely to be operating in breach of consumer law.
The letter is an enforcement lever, not a fine. Suppliers who ignore it invite the CMA back with formal powers. Suppliers who quietly rewrite their terms and refund customers who were badly treated get to move on. That is the settlement the regulator is offering.
Why the CMA wrote it
The background sits in the price spike earlier in 2026 when Middle East tension pulled kerosene wholesale prices up sharply. The CMA has been reviewing the heating oil sector, and its published findings describe hundreds of consumers whose orders were cancelled by suppliers after the market moved against the price they had been quoted. Many of those orders had already been paid for. The CMA secured voluntary compensation from the suppliers involved, and the September letter is the public follow-up: the regulator is now telling the rest of the industry that the same behaviour will draw the same response.
The Norfolk relevance is straightforward. Norfolk has one of the higher shares in England of homes off the mains gas network, and in the rural districts of North Norfolk, Breckland and King’s Lynn and West Norfolk the proportion of oil-heated households runs into the tens of thousands. When wholesale prices move quickly the phones at every Norfolk oil depot ring at once, and the pinch point in the system falls hardest on the households who ordered the day before a spike.

Three things to check in your supplier’s terms
Most Norfolk oil suppliers publish their terms on their website or send them with the order confirmation. It is worth reading them once, particularly around these three points:
- What happens if the supplier cannot deliver at the price quoted. A fair clause explains that if the price moves before delivery, the supplier will contact you and you can accept the new price or cancel for a full refund. An unfair clause says the supplier can cancel and keep an administration fee, or that the “price at delivery” is whatever the supplier decides it is.
- How long the supplier has to deliver after payment. A fair clause names a window, typically 10 to 14 working days in busy periods, and commits to refunding you if it is not met. An unfair clause disclaims all liability for delay and offers no window at all.
- What the supplier accepts responsibility for if delivery fails. A fair clause distinguishes between causes genuinely outside the supplier’s control (severe weather, wholesale supply cut-off) and its own operational failures. An unfair clause tries to disclaim all liability across the board, which is exactly the practice the CMA has now called out.
None of this requires reading contract law for a living. If a clause looks as if it lets the supplier keep your money without delivering the oil, it is precisely the sort of clause the CMA has told suppliers is unlikely to hold up.
What to do if your order goes wrong
The route to a resolution is a short ladder. Most Norfolk households never need to climb past the first rung.
- Complain in writing to the supplier. Email is fine and creates the paper trail you need. Ask specifically for delivery or a full refund and reference the CMA’s September 2026 open letter on fair terms. Give a deadline: seven working days is reasonable.
- If the supplier refuses or ignores you, contact Citizens Advice consumer service on 0808 223 1133. Citizens Advice logs the complaint and passes the details to Trading Standards, which is the local authority body with enforcement powers. In Norfolk that is Norfolk County Council Trading Standards.
- If you paid by credit card and the amount is over £100, use Section 75. Section 75 of the Consumer Credit Act makes your card provider jointly liable if the supplier fails to deliver. It is a faster route to your money back than court action.
- If you paid by debit card, ask your bank for a chargeback. Chargeback is not a statutory right in the same way, but most UK banks operate the scheme voluntarily and will pursue the supplier on your behalf. Time limits are tight, usually 120 days from the transaction.
- Small claims as a last resort. The Money Claim Online service handles claims up to £10,000. It is deliberately designed for people without solicitors. Court fees start at £35.
What the letter does not cover
Two things worth being clear about. First, the CMA is not setting a price cap on heating oil. The letter is about how suppliers behave once a price has been agreed, not what that price should be. Kerosene will continue to move with the wholesale market, and a supplier is free to raise its published price at any time. What it cannot do is take your money at one price and then refuse to honour the order.
Second, buying-club orders through informal Norfolk oil syndicates sit in a slightly different legal position. The contract is normally between each household and the supplier, with the syndicate coordinator acting as messenger rather than as counterparty. If a syndicate order is cancelled, each household has its own consumer relationship with the supplier and can pursue the routes above individually. It is worth checking who the payment actually went to.
The wider point
Norfolk’s oil-heated households have lived for years with a market that has fewer consumer protections than mains gas, no Ofgem price cap, and no realistic switching mechanism during a supply crunch. The CMA’s letter does not fix that structural imbalance. It does tighten the corner of it that was doing the most damage: suppliers who took payment and then walked away when the numbers moved against them. For a Norfolk household filling a 1,200 litre tank at £850, that is not a small correction.
The right response in most homes is not to do anything different, since most Norfolk oil suppliers behave decently most of the time. It is to know that if a supplier does not, the regulator has now told them where they stand and the household on the other end of the transaction is not on their own.

Frequently asked questions
Where do I actually complain about a Norfolk oil supplier?
First, to the supplier in writing. If that fails, Citizens Advice on 0808 223 1133 logs the complaint and refers it to Norfolk County Council Trading Standards, which has the local enforcement remit. Serious or widespread issues also go to the CMA under its published heating oil review.
Can I refuse to pay if delivery is late?
If you have not yet paid, yes. If you have paid and the supplier is materially in breach of its delivery obligations, you can cancel the contract and demand a refund. The CMA’s letter makes clear that a contract clause purporting to strip you of that right is unlikely to be enforceable.
Does this cover buying-club orders?
Yes, provided the payment went from your household to the supplier. Norfolk oil syndicates usually operate on that basis, with the coordinator organising the round rather than taking the payment. If money was paid to the coordinator instead, the contract chain is different and the rights outlined here run against them rather than the supplier.
Is the CMA capping heating oil prices?
No. There is no price cap, and the September 2026 letter does not create one. The CMA’s remit here is contract fairness, not price control.
