What does an emergency delivery cost?

Emergency heating oil typically costs 8–15p per litre more than a standard delivery — on a 500 litre order that is £40–£75 extra. Ordering before your tank drops below a quarter full almost always avoids this cost.

Run-out calculator FAQs

How accurate is the run-out date?
It is a helpful estimate based on the information you provide. Actual usage changes with weather, boiler efficiency and how warm you keep your home.
What should I do if I am nearly out of oil?
Order as soon as possible and tell the supplier you need a priority delivery. Avoid running the boiler completely dry where you can.
How much oil should I order?
A 500 litre delivery is common, but check your tank safe fill level and leave room for expansion. Never fill above 90% of the capacity.
Can I use this in winter?
Yes. Choose Winter to start with an 18 litre daily estimate, then adjust it to match your household recent usage.
What does an emergency delivery cost extra?
Emergency heating oil typically costs 8 to 15p per litre more than a standard delivery — on a 500 litre order that is £40 to £75 extra.
