Shop slimline oil tanks for narrow spaces, side access and tighter installation areas. This range includes slimline heating oil tanks in bunded and single skin options, with plastic and steel models available depending on the installation.
Slimline tanks are useful where width is limited, but you still need practical heating oil storage. Customers often choose them for side paths, garden boundaries, tight access routes or properties where a standard tank shape may not fit.
Narrow oil tanks can vary in length, height and footprint, so compare the full dimensions before ordering. If you need extra containment, view the slimline bunded oil tanks. If your site can use a single skin tank, check the single skin options carefully before buying.
Before ordering, confirm the base, delivery access and installation route. If you are unsure which narrow oil tanks are suitable, contact us and we can help you compare slimline oil tanks.
Check The Space Before You Choose
Slimline oil tanks are useful when width is limited, but it is still important to check the access route, final base area, height, fittings and delivery route before ordering.

Slimline Oil Tank Questions
Open the questions that matter before choosing a tank or booking delivery.
What is a slimline oil tank?
A slimline oil tank is designed to take up less width than a standard tank, making it useful for narrow side paths, smaller gardens and tighter installation areas. You still need to check the full length, width, height and footprint before ordering.
Should I filter by access width or base width?
Use access width if the tank has to pass through a gate, alleyway or narrow route to reach its position. Use base width if your main concern is the final prepared area where the tank will sit.
Are slimline oil tanks always bunded?
No. Slimline tanks can be bunded or single skin. Bunded tanks include secondary containment and are often the safer choice for many installations. Single skin tanks should only be used where the site is suitable and regulations allow.
Can I replace my old tank with a slimline tank?
Often yes, but you should compare the old tank size, pipework position, base condition and access route. A slimline tank may solve a width issue, but it can be longer or taller than the tank it replaces.
Do I need a new base for a slimline oil tank?
The tank should sit on a suitable, level and stable base. Check the tank footprint and manufacturer requirements before delivery. Do not assume an old base is suitable just because the previous tank fitted there.
What should I check before ordering?
Check the tank capacity, full dimensions, footprint, weight, delivery access, base size, outlet position, gauge option and fitting kit details. If access is tight, measure more than once before ordering.
Do slimline tanks include a gauge or fitting kit?
Some slimline oil tanks include a fitting kit, gauge or monitor, while others have different options. Always check the individual product page so you know exactly what is supplied with that tank.
What if I am not sure it will fit?
Contact us before ordering. We can help compare dimensions, capacity, access width and delivery requirements so you do not choose a tank that is unsuitable for your site.
