Guide to Buying Home Heating Oil
Whether you're ordering heating oil for the first time or simply want to get better value from your next delivery, understanding what to look for can help you save money, avoid disruption, and choose a supplier you trust.
This guide covers everything you need to know before placing an order - from the different types of heating oil available to delivery access, pricing, and tank checks.
What Is Home Heating Oil?
Home heating oil is a liquid fuel used to heat homes through an oil-fired boiler or AGA cooker. It is typically stored in a domestic heating oil tank and delivered in bulk by a tanker.
In the UK, the most common fuel used for home heating is kerosene (also known as 28-second oil) due to its clean burn, high efficiency, and suitability for modern boilers.
What Types of Heating Oil Are Available?
Most households will use one of two types of fuel:
Kerosene (Standard Heating Oil)
- The most common domestic fuel
- Suitable for modern boilers and cookers
- Burns cleanly and efficiently
- Typically lower cost than premium alternatives
Premium Kerosene
Premium heating oil, also known as K+, includes additives designed to improve boiler performance and reduce deposits. Benefits include:
- Better fuel efficiency
- Improved boiler reliability
- Reduced risk of sludge build-up
- Lower long-term maintenance costs
What to Consider Before Buying Heating Oil
1. The Size and Condition of Your Oil Tank
Before ordering, check your tank for:
- Signs of damage or leaks
- Water contamination or sludge
- A clear, accessible fill point
If your tank needs replacing or upgrading, this may affect what type of oil is appropriate and how much you can store.
2. How Much Heating Oil You Need
The amount of oil you require depends on:
- Tank capacity
- Home size
- Boiler age and efficiency
- Frequency of heating
Most UK households order between 500–1,500 litres at a time. Ordering larger volumes can help secure a better price per litre, but always ensure you have enough tank capacity. You can also try our heating oil calculator as a guide.
3. Delivery Access
Before placing an order, consider:
- Can the driver easily access your tank?
- Is the fill point reachable with a hose?
- Are there obstacles, locked gates, or narrow driveways?
Clear access helps ensure safe, efficient delivery - particularly during winter months when demand is at its peak.
4. Pricing and Market Conditions
Heating oil prices fluctuate based on factors such as:
- Seasonal demand
- Global oil markets
- Supply availability
- Delivery location
To secure the best deal, consider:
- Ordering during off-peak months
- Monitoring heating oil prices on a regular basis
5. Choosing a Reliable Supplier
When selecting a heating oil supplier, look for:
- Competitive, transparent pricing
- Convenient delivery slots
- Long-standing local reputation
- Excellent customer service
- Secure online ordering

How Do I Know If I Need a Heating Oil Delivery?
You may need to order heating oil if you notice:
Your Tank Level Is Low
If your gauge, dipstick, or sight tube shows the oil is running low, it’s time to order - ideally before it drops under 25% to prevent emergency callouts.
Your Boiler Isn’t Running Efficiently
Sputtering, slow heating, or an unresponsive boiler can indicate very low oil or contamination.
Your Home Takes Longer to Heat Up
Reduced heating performance can be a sign of degrading fuel or sludge in your tank.
