Heating oil has had a bumpy 2026. Global tensions pushed crude oil sharply higher earlier in the year, and because UK heating oil (kerosene) is priced in pence per litre off the back of those same global markets, the tank you fill for autumn has been costing noticeably more than it did a year ago. This isn't scaremongering — it's the reason so many Wiltshire households have been ringing round for quotes before the cold weather bites.
| Question | Quick answer |
|---|---|
| Why has heating oil been expensive? | Global tensions — particularly around the Strait of Hormuz — squeezed crude supply, and UK kerosene tracks that. |
| Is there relief in sight? | Some easing since the summer peak as tanker traffic normalised, but the market stays choppy. |
| What are Wiltshire delivery costs doing? | Tracking the national trend — ordering early, before the autumn rush, usually beats a panic fill. |
| Is my tank part of the cost problem? | A leaking or corroded tank wastes every litre of increasingly expensive oil, so annual servicing matters more this year. |
| What does replacing a tank cost? | Single-skin roughly £1,200–£2,200, bunded £1,800–£3,500, fully fitted — confirmed after a free survey. |
| Fill up now or wait? | Smaller, more frequent loads spread the risk better than one big fill at an unpredictable price. |
The headline is simple: global supply took a hammering. Tension around the Strait of Hormuz — the choke point a large share of the world's oil passes through — disrupted tanker traffic and pushed crude sharply higher. That kind of shock doesn't stay contained to crude; it flows straight through to distillates like heating oil, which is why your fill has felt so much more expensive this year.
Kerosene and diesel move together during supply shocks, and both hit multi-year highs in the spring of 2026 before easing back. The scars on the market are still visible every time crude moves on the news.
Most summers, heating oil dips because demand is low and refiners are quietly stockpiling for winter. This year has been different. With tankers not moving normally, the usual summer softening was muted — and even as traffic resumed and crude fell back through the summer, the market hadn't fully shaken off the shock. One calmer month doesn't undo the pricing pressure already baked into this year's fills.
UK heating oil eased from its summer peak by early August 2026, but it's still well up on this time last year. Because kerosene is priced in pence per litre and follows global crude, the figure a supplier quotes you can shift week to week — even day to day during a volatile spell.
The honest takeaway: don't assume the summer dip will last, and don't assume it won't. Check the current pence-per-litre with two or three suppliers before you commit, and factor in that demand builds again as winter approaches.
National price swings land differently depending on where you live, and rural Wiltshire is no exception. Off-grid homes across Salisbury, Chippenham, Devizes and Swindon rely on oil rather than mains gas, so a global price spike hits harder here than in cities with alternative heating — and local households also carry the extra risk of ageing tanks in exposed, rural settings. We cover the whole county; if you want to confirm we reach your village, see the areas we serve.
Everyone wants a straight answer, and honestly the market doesn't allow for one this year. Summer is usually the cheapest window, but 2026 has been jumpy enough that one big fill is a gamble on timing. Rather than betting everything on a single order, many households are taking smaller top-ups more frequently, spreading out the risk of buying at the wrong moment.
What we can say with confidence: a tank in poor condition makes this decision worse, not better. Every litre lost to a slow leak is a litre bought at 2026 prices and wasted.
When oil costs this much, a badly maintained tank isn't just an environmental risk — it's a financial one. A tank that's quietly corroding or weeping at the seams can leak away hundreds of pounds of fuel before anyone notices. Most home insurance policies also expect oil tanks to be maintained, and a leak from a neglected tank can be expensive to clean up and may not be covered at all. An annual tank service is the cheapest insurance you'll buy this year — and a lot less painful than finding a split seam after your fill.
If your tank is past its best, doing the work now — before the autumn rush and before another price jump — makes financial sense. Here's what typical oil tank replacement costs look like in 2026:
| Item | Typical cost |
|---|---|
| Single-skin tank, supplied & fitted | £1,200 – £2,200 |
| Bunded tank, supplied & fitted | £1,800 – £3,500 |
| New concrete base | £300 – £800 |
| Standalone tank removal | £250 – £600 |
| Larger / commercial tanks | From £3,500+ |
The price difference over single-skin is small compared with the cost of a pollution clean-up or a failed insurance claim, and bunded is usually the only compliant option anyway.

When a tank starts to corrode, leak or simply reaches the end of its life, you want a genuinely local team who can be out quickly, not a national booking line. Our team are generally busy out on installs — drop us a message and someone will come back to you as soon as possible. We offer same-week availability for genuine leaks and pollution risks, and free site surveys so you get a fixed, honest quote with no hidden extras.
Our oil tank replacement service covers supply, fit, sign-off and removal of the old tank; our installation service handles the base, pipework and paperwork to current building-regulation standards; and if your old tank simply needs taking away safely, our removal and disposal service deals with the hazardous-waste side properly — no skips, no shortcuts.
2026's price alert boils down to one uncomfortable truth: global tensions have made your fill more expensive, and prices may not fall far this year. What you can control is how much of that expensive oil actually stays in your tank and reaches your boiler. A serviced, compliant, well-maintained tank protects every litre you buy — if yours is leaking, corroded or simply old, get in touch and we'll survey it properly before you commit to another season of guesswork.
Global supply shocks — notably tension around the Strait of Hormuz — squeezed crude oil and the distillates made from it, including the kerosene most UK homes burn. UK heating oil is priced in pence per litre and tracks those global moves, so 2026 has run well above recent norms.
Prices eased back from the summer peak once tanker traffic began to normalise, but the market is still jumpy, so a big further drop before winter isn't guaranteed. Check the current pence-per-litre with two or three suppliers before you commit to a fill.
Summer is historically the cheapest window, but 2026 has been unusually volatile. Many households spread the risk with smaller, more frequent top-ups rather than betting everything on one large fill at an unpredictable price.
A single-skin tank supplied and fitted typically costs £1,200 to £2,200, while a bunded tank runs £1,800 to £3,500 depending on size and site access. We give a fixed quote after a free site survey rather than a vague "from" price.
A bunded tank is required wherever a risk assessment shows a leak could reach a watercourse, drain, borehole or hard surface — which covers most rural Wiltshire properties given the county's chalk streams and permeable soils.
Yes. Every litre lost to a weeping seam is oil you paid 2026 prices for, on top of the clean-up and pollution risk. Servicing or replacing an ageing tank protects the fuel you buy.
