What you can expect to pay to replace, install or remove an oil tank — what drives the price up or down, and how to get an exact figure for your property.
"How much does it cost to replace an oil tank?" is the first question almost everyone asks — and the honest answer is "it depends." Tank size, bunded vs single-skin, the state of the base and the pipework run all move the price. Below are realistic guide ranges, followed by exactly what affects them. (Figures are indicative for 2026 and should be confirmed with a free survey — they are a guide, not a quote.)
| Job | Typical UK range* | Notes |
|---|---|---|
| Single-skin tank, supplied & fitted | £1,200 – £2,200 | Where a risk assessment permits single-skin |
| Bunded tank, supplied & fitted | £1,800 – £3,500 | Most common; required in most positions |
| New concrete base | £300 – £800 | If the existing base isn't suitable |
| Standalone tank removal | £250 – £600 | Free when fitted alongside a replacement |
| Larger / commercial tanks | From £3,500+ | Priced individually |

A bunded tank has a "tank within a tank" for spill protection, so it costs more than single-skin. Most modern installs require bunded, so it's the realistic figure to budget for.
A standard 1,000–1,350 litre domestic tank is the most common. Larger capacities cost more — see our oil tank sizes guide.
If your existing base is sound and the right size, you save money. If it needs replacing or relocating, add the base cost above.
Tight access, long oil supply runs or moving the tank to a new compliant position all add labour and materials.
Usually included free with a replacement. As a standalone removal it's priced separately.
As a guide, a domestic replacement typically ranges from around £1,500 to £3,500 supplied and fitted, depending on size, type and site work. A free survey gives you the exact fixed price.
A standalone removal usually costs a few hundred pounds depending on size, access and any contamination — and it's normally free when you have a replacement fitted.
A bunded tank has a second outer skin for spill protection, so it uses more material — but it's required in most modern installations.
