Can you help me compare heating oil prices before ordering?
Yes. We can help you compare heating oil prices by checking that quotes cover the same quantity, delivery conditions and additional charges before you order.
The lowest price per litre is not always the lowest-cost order. To compare heating oil quotes properly, check that each supplier is pricing the same fuel, on the same terms, with all charges and conditions shown clearly.
Start by recording the date and time of each quote. Heating oil prices can change, so ask how long the quoted rate remains valid. A quote that looks cheaper may no longer apply when you place the order. Keep the quote or confirmation so you can check the final invoice against what you agreed.
Check whether the price includes VAT. The treatment can vary according to the fuel and how it is used, so the quote should state the rate rather than leave you to work it out. Also check for payment fees, cancellation charges or other costs that only appear in the supplier’s terms.
Make sure every quote is for the correct fuel. Most domestic oil boilers use kerosene, often called 28-second oil. Gas oil is a different fuel and should not be treated as an interchangeable option for a domestic boiler. If you are unsure what your system uses, check the boiler or tank information before ordering.
Your tank gauge gives only an estimate of the remaining fuel. Tank shapes vary, and the gauge may not show the usable capacity accurately. Before accepting an order, compare the proposed fill with the tank’s safe capacity and leave room for the fuel already in the tank. An order that exceeds the available space can create a safety problem and may lead to wasted cost.
Delivery terms can also affect the real price. Ask whether the quote assumes clear access to the tank, a particular hose length or someone being present. If access is difficult, check what happens if the driver cannot reach the fill point. The cheapest quote is less useful if its conditions do not suit the property.
For an older or rural property, check the tank before committing to a large order. A tank with corrosion, damaged supports, leaking joints or a failing gauge may need attention before it is filled. Ordering more fuel does not solve a tank problem, and a leak can cause environmental damage as well as expense.
It is also worth comparing the order against your recent use rather than choosing an amount from the price alone. Look at previous invoices, boiler usage and the time of year. A larger order may appear attractive if the rate is lower, but tying up money in fuel is not helpful if the tank cannot safely hold it or your usage has changed.
A useful comparison record includes:
- the fuel type and quoted price per litre;
- the date and expiry time of the quote;
- VAT and any payment or administration fees;
- the expected volume and the tank’s available capacity;
- the delivery assumptions and access requirements;
- the supplier’s terms for failed delivery, cancellation or changes; and
- the invoice or confirmation issued after ordering.
If the figures still do not line up, ask the supplier to explain the difference in writing. A clear quote should let you see what you are paying for without relying on an advertised headline rate.
We can also help you consider the wider condition of an oil-fired heating system before you plan its next fill. If the boiler, tank or fuel line is becoming unreliable, comparing one delivery after another may only delay a more suitable repair or replacement decision.

If one quote is for a full tank and another is for a top-up, the prices are not directly comparable. Ask each supplier to quote for the same quantity, then check that the amount fits safely within the tank’s usable capacity.
That gives you a clearer comparison between suppliers and helps prevent an attractive rate from leading to an unsuitable order.
