Shop large oil tanks for higher-capacity heating oil storage. This range includes plastic and steel options for larger homes, farms, commercial-style sites and installations where a standard domestic tank may be too small.
Large capacity oil tanks are useful when you want fewer refills, more storage on site or a tank suited to heavier usage. Before ordering, check the full dimensions, weight, footprint, delivery access and off-load requirements.
For bigger sites, compare commercial oil tanks by capacity, material and delivery requirements. If shape is the main issue, slimline tanks help with width, while low profile tanks help with height.
Plan The Site Before You Choose
Large oil tanks are not just bigger versions of standard domestic tanks. Capacity, material, delivery access, base size and off-load method all matter more as tank size increases.

Open the questions that matter before ordering a larger tank or arranging delivery.
What counts as a large oil tank?
On this page, large oil tanks generally means higher-capacity tanks above the usual smaller domestic ranges. They may be used for larger homes, farms, commercial-style sites or higher fuel usage.
Should I choose plastic or steel?
Plastic tanks are often popular for domestic and property storage. Steel tanks may be preferred where a more robust build, larger capacity or site-specific construction is important.
Do large tanks need customer off-load?
Many larger tanks require customer off-load, especially where delivery is by HGV or articulated vehicle. You may need a forklift, telehandler or other suitable lifting equipment on site.
Can large tanks be delivered by tail lift?
Some smaller large tanks may be suitable for tail lift delivery, but this depends on the size, weight and delivery method. Bigger tanks often need planned off-load equipment or a HIAB option where available.
Do I need a bunded large oil tank?
Bunded tanks include secondary containment and are usually the preferred option for secure heating oil storage. Site requirements should always be checked before choosing any tank.
What should I check before ordering?
Check the capacity, dimensions, footprint, base size, site access, delivery restrictions, off-load requirements and whether the tank includes the fittings or gauge setup you need.
Can I use a large tank for domestic heating oil?
Yes, larger tanks can be used for domestic heating oil where the site is suitable and the capacity is appropriate. Larger homes or high-use properties may choose more storage to reduce refill frequency.
What if access is restricted?
If access is tight, check the full delivery route before ordering. Narrow lanes, weak bridges, low branches, tight turns or lack of off-load space can affect whether a large tank can be delivered safely.
