When you buy heating oil, it’s easy to focus only on the headline price per litre, but that’s not always the full story. Many suppliers add extra charges that can quietly drive up your total bill, especially during busy winter periods.
At HeatOilCompare.com, our goal is to help customers understand the real costs behind heating oil so you can make informed decisions and avoid nasty surprises.
Here’s what you need to know about the hidden fees that might be lurking in your next delivery.
1. Delivery Fees
Most suppliers include delivery in the per-litre price, but not always. Some charge extra depending on how far you live from their depot or how quickly you need the oil.
Common delivery fee types:
- Standard delivery: Usually free or included in the base price. (14-16 days)
- Express delivery: Costs extra if you need oil within (7-9 days)
- Emergency delivery: Costs extra if you need oil within (24 – 72 hours)
- Remote area surcharge: If you live in a hard-to-reach area or rural postcode, suppliers might charge for travel time or limited access.
Tip: When comparing quotes, always check if delivery costs are included. What looks like the cheapest price at first might not be once fees are added.
2. Emergency Surcharges
If you’ve ever run low in the middle of winter, you know how stressful it can be, and suppliers know it too. Emergency or “next day” deliveries often come with steep surcharges.
- Emergency callouts can cost anywhere from £20 to £60 extra, depending on location.
- During peak cold spells, these fees can climb even higher due to increased demand.
- Some suppliers may also prioritise larger orders, leaving smaller emergency top-ups with extra costs or longer wait times.
How to avoid it:
Keep an eye on your oil levels with a tank monitor or set a reminder to check your gauge weekly during winter. Topping up early is always cheaper than paying for an emergency delivery.
3. Small Order Charges
Suppliers often charge more for small orders. The reason? Delivery costs don’t change much whether you order 300 litres or 1,000 litres, so smaller orders cost them more per litre to deliver.
Example:
Ordering 500 litres might cost 70p per litre, but ordering 1,000 litres could drop the price to 65p per litre saving £25–£30 overall.
Tip: If possible, buy in bulk or join a local buying group to share delivery costs with neighbours.
4. Hidden Maintenance Costs
Even though it’s not a delivery fee, don’t forget the indirect costs of heating oil ownership:
- Tank cleaning and inspection (recommended every 3–5 years)
- Boiler servicing to maintain efficiency
- Filter or line replacements if sludge builds up
Keeping your system in good shape prevents breakdowns and ensures you get the most from every litre.
How to Avoid Hidden Costs
Here are some simple ways to keep your heating oil bills transparent and manageable:
- Compare quotes properly – Make sure you’re comparing total prices, not just the per-litre rate.
- Plan ahead – Avoid emergency deliveries by topping up before winter.
- Buy in bulk – Larger orders usually mean cheaper prices and fewer fees.
