A tanker delivering to twenty addresses in one lane is a cheaper round than a tanker delivering to twenty addresses across three parishes. That is the entire mechanism. Everything else about oil clubs follows from it.
How it works in practice
- 01A coordinator, usually a volunteer, collects orders from members over a window of a week or two.
- 02The aggregated volume goes out to two or three suppliers as a single enquiry for one delivery date or window.
- 03The suppliers quote a rate for the whole round. Members pay the supplier directly at that rate.
- 04The coordinator takes nothing, or a small annual membership that covers admin. A group where the coordinator takes a per litre cut is a broker wearing a village hall.
What it actually saves
We do not publish a pence per litre saving, and you should be suspicious of anyone who does. No public series measures group purchase rates, so any national figure is either taken from a group promoting itself or invented. What can be said is where the saving comes from and therefore when it is largest.
| Condition | Effect on the saving |
|---|---|
| Tight geographic cluster | Largest. The round is genuinely cheaper to run. |
| Scattered members over many miles | Small. You have aggregated volume but not density. |
| Order window in a quiet month | Larger. Depot capacity is available. |
| Order window during a cold snap | Smaller or nil. Everyone wants the same tanker. |
| Members who can take any date | Larger. Flexibility is what the depot is buying. |
| Members who need a specific day | Smaller. That is the same constraint as an individual order. |
The catches
- You order in the group window, not when you want. If your tank hits a third the week after the window closes, you are back to buying alone.
- There is usually a minimum per member, commonly 500 litres, so the households with the smallest budgets are sometimes the ones who cannot join.
- You take the group supplier. If you have a service relationship with a different one, weigh that before switching for a few pence.
- Payment is to the supplier, not the coordinator. Any group that wants your money into a personal account is not a group you should join.
Starting one
Twenty households at 1,000 litres is a 20,000 litre round, which is a real conversation with a depot rather than a favour. At 90.01p that round is worth GBP 18,002.00 to whoever gets it. Approach two or three depots with the volume, the postcode cluster and a date window, and ask them to quote against each other.
The rural community networks are the usual starting point for finding an existing group. If there is not one, a parish council notice and a shared spreadsheet is genuinely all the infrastructure this requires.
