Domestic Oil Tank Installations

Worried about an old or damaged oil tank? Corroded or poorly installed tanks can leak, pollute the environment, and even pose serious fire risks. If your tank is over 15 years old, showing signs of wear, or no longer meets current safety standards, it’s time to consider a replacement.

At GasWise, our OFTEC-registered engineers specialise in new oil tank installations that prioritise safety, efficiency, and long-term peace of mind. Whether you're upgrading an ageing tank or moving to a more suitable location on your property, we tailor the solution to your exact needs.

When You Should Consider a New Oil Tank

There are several common signals that you may need a new oil tank, such as:

Leaking or Corroded Tanks: Metal tanks degrade over time, risking fuel leaks and soil contamination.
Non-Compliant Bunding: Older tanks often lack an adequate secondary containment bund.
Capacity Shortages: As heating needs grow, small tanks can run low too quickly in winter.
Poor Tank Positioning: Incorrect siting can make fill-ups difficult and unsafe.
Failed Tank Surveys: Tanks not meeting OFTEC or Environment Agency standards must be replaced.

Not sure whether you need a new oil tank? Book a site survey, and our engineers will identify any risks and recommend the right solution.

What Size Oil Tanks Do We Install?

At GasWise, we fit a variety of domestic oil tank sizes to suit every property and fuel requirement:

Compact Tanks

(650l - 1400l)

Perfect for smaller properties, tight garden spaces, or garage installations. These tanks are typically slimline or single-skin designs that fit neatly into alcoves while still meeting safety regulations. Ideal for households with moderate heating demands and limited outdoor space.

Space-saving design
Easy to install in restricted areas
Great for bungalows, cottages, or holiday homes

Horizontal Tanks

(1,200L–2,500L)

The most popular choice for standard homes, horizontal tanks offer a balance of capacity and accessibility. Available in twin-skinned plastic or steel, their low profile makes them easier to refill and service, while still providing plenty of fuel for larger homes.

Versatile and widely used
Easy to access for refilling
Suitable for most suburban and rural homes

Vertical Drum Tanks

(2,500L–9,500L)

Need maximum capacity without sacrificing ground space? Vertical drum tanks are a smart solution. These bunded tanks are designed for high-usage households and properties with larger heating systems. Their vertical structure allows substantial fuel storage with a smaller footprint.

High-capacity fuel storage
Fully bunded for environmental safety
Ideal for larger rural homes or farms
