A slimline bunded oil tank is a space-saving heating oil storage solution featuring a 'tank within a tank' design. These tanks are specifically engineered with a narrow width to fit into restricted spaces, such as down the side of a house or between a boundary fence, while still providing 110% secondary containment for environmental safety.
While dimensions vary by capacity, slimline tanks are designed to be significantly narrower than standard horizontal tanks. Most models range from 650 to 2000 litres, with widths often starting as narrow as 650mm, allowing them to pass through standard gates and fit into tight garden passages.
Yes. The Tank Shop offers both high-grade UV-stabilised plastic (polyethylene) and heavy-duty welded steel slimline tanks. Plastic models are popular for their lightweight and low-maintenance properties, while steel slimline tanks offer maximum security and can be custom-fabricated to exact bespoke dimensions.
Slimline tanks must follow the same fire safety regulations as standard tanks. Generally, they should be 1.8m away from non-fire rated structures or openings. If space is extremely limited, we offer 'Fire Pro' slimline models with integrated fire protection that allow for closer installation to boundaries and buildings while remaining compliant.
For a standard 3-bedroom home, a 1000-litre or 1100-litre slimline tank is usually the most popular choice. It provides a balance between a compact footprint and enough capacity to take advantage of bulk fuel delivery discounts.
Like all oil tanks, slimline models must be installed on a flat, level, and fire-resistant base (such as 50mm concrete slabs). Because they are taller and narrower than standard tanks, ensuring the base is perfectly level and extends 300mm beyond all sides is critical for the tank's stability and long-term structural integrity.
We stock slimline models from the UK's leading manufacturers, including Titan, Harlequin, Carbery, Tuffa, and Atlantis. These brands are chosen for their proven durability in the UK climate and their comprehensive manufacturer warranties.
No, provided they are installed correctly on a professional base. Slimline tanks are engineered with a stable center of gravity; however, it is vital that the base is solid and fully supports the entire underside of the tank to prevent any shifting or leaning over time.
