Product Description

1250 Litre Slimline Plastic Bunded Oil Tank – Tuffa Tanks

The Tuffa 1250 Litre Slimline Bunded Oil Tank offers an innovative, space-saving solution for storing heating oil where installation space or access is restricted. Introduced in 2026, this new design measures just 600mm wide, making it the narrowest bunded oil tank of its capacity on the market.

Its exceptionally slim profile makes it particularly suitable for properties with narrow side passages, restricted garden access or limited installation space, without compromising on storage capacity.

Manufactured from durable, corrosion-resistant polyethylene, the tank features a fully bunded construction, with an inner oil storage tank protected by a secondary outer containment tank providing 110% capacity. This additional protection helps safeguard against leaks and reduces the risk of oil escaping into the surrounding environment.

For added security, the tank incorporates an integrated lockable cabinet, supplied with a lock and two keys as standard. The cabinet provides convenient access to the tank’s filling and monitoring connections whilst helping prevent unauthorised access.

The Tuffa 1250SLB is suitable for storing standard heating oil, HVO fuel and HVO blends, offering a versatile, future-ready storage solution for domestic and commercial installations.

  • 1″ Bottom Outlet Kit – (1″ – 1/2″ adaptor, ball valve and filter)
  • Manual float level gauge
  • Lockable flip lid with two keys
  • The bund contains a minimum 110% volume of the inner tank

Optional Extras 

  • Watchman Sonic – an electronic oil level sensor which remotely monitors the level of fuel in the tank.
