Bunded Fuel Tank Questions Answered
01 The basics
What is a bunded fuel tank?
A bunded fuel tank has a tank within a tank: the inner vessel holds the fuel, and the outer bund provides secondary containment if the inner tank ever leaks. See our full guide on what a bunded fuel tank is for the complete explanation.
Do I legally need a bunded fuel tank?
If your business stores more than 200 litres of fuel or oil above ground, you almost certainly do under UK oil storage regulations. See our guide on whether you legally need one for the specific thresholds.
Where can I find bunded fuel tanks near me?
We're based in Nelson, Lancashire, and manufacture all our tanks in the North West of England, with delivery available UK-wide.
Do you supply tanks for both commercial and domestic use?
Yes, from small tanks for home heating oil to large-scale industrial and commercial fuel storage, all built to the same UK safety standards.
02 Choosing a tank
What size bunded fuel tank do I need?
It depends on your fuel usage, how often you want to take deliveries, and your site's space and access. See our tank sizing guide for how to work it out, or get in touch and we'll recommend a size.
Should I choose steel or plastic?
Steel lasts longer (typically 25-30 years vs 10-15 for plastic) and is far more resistant to tampering and theft; plastic is lighter and cheaper upfront for smaller needs. See our steel vs plastic comparison for the full breakdown.
What materials are your tanks made from?
High-grade 43A steel, built to comply with current UK safety regulations.
Can I get a custom or bespoke tank?
Yes, we design and manufacture bespoke tanks to your specification, including multi-compartment builds, custom colours and specialist fittings. See our custom bunded fuel tanks page.
What size tank do I need for a generator?
Size it around your generator's fuel consumption rate and required runtime, not just a round number. See our generator fuel tank sizing guide.
03 Costs & hire
How much does a bunded fuel tank cost?
It varies significantly by size, material and fittings. See our bunded fuel tank cost guide for typical UK price ranges by capacity, or request a quote for an exact figure.
Is hiring cheaper than buying?
For short-term or uncertain-duration needs, hiring is usually more cost-effective; for long-term use, buying typically works out better value. See our fuel tank hire guide for the full comparison.
Can I hire a fuel tank short-term?
Yes, hire is available from 60 days, with flexible extension. See our fuel tank hire guide for costs and contract details.
04 Regulations
What are the rules on bunded fuel tanks?
The main UK legislation is the Control of Pollution (Oil Storage) Regulations, requiring bunded containment for most businesses storing over 200 litres. See our full bunded fuel tank regulations guide.
Are the rules different for farms?
Yes, agricultural fuel storage has its own exemption threshold and falls under the Silage, Slurry and Agricultural Fuel Oil Regulations (SSAFO) above that. See our agricultural fuel storage rules guide.
Can I still use red diesel?
Only for specific permitted uses. Since the April 2022 reform, farming and a handful of other sectors are still entitled. See our red diesel rules guide for the full list.
05 Installation & aftercare
How is a bunded fuel tank installed?
Tanks need a proper fire-resistant, load-bearing base and correctly positioned fill points. See our Delivery & Installations page for what to expect.
Do bunded tanks need servicing?
Yes, annual servicing checks for water/sludge build-up, valve operation and gauge accuracy. See our Annual Tank Servicing page for what's included.
How do I protect my tank in winter?
Regular checks on paintwork, seals and gauges go a long way. See our guide to protecting a bunded fuel tank in winter for the full checklist.
How can I prevent fuel theft from my tank?
Steel construction, a lockable cabinet, good site positioning and a fuel management system are the main defences. See our guide on preventing fuel theft on site.
What warranty do you offer?
All our tanks come with a 20-year guarantee warranty as standard, and pumps and accessories carry a 12 month manufacturer's warranty. See our Tank Warranties page for details.
