Will my New Brunswick insurer refuse coverage over an aging oil tank?

Yes, this is a real and growing concern in New Brunswick — many insurers are either refusing coverage outright or adding significant exclusions for aging oil tanks, particularly those over 15-20 years old.

Insurance companies across the province have become increasingly strict about residential oil storage tanks over the past decade, and for good reason: a failed tank can release hundreds of litres of heating oil into soil and groundwater, with remediation costs easily reaching $50,000–$200,000+. Insurers don't want that liability on their books.

What triggers insurer concern in NB:

• Tanks older than 15-20 years (many insurers set a hard cutoff)
• Single-wall steel tanks (the old standard — highly corrosion-prone)
• Tanks stored in damp basements or directly on concrete floors without a proper containment tray
• No visible inspection tag or documentation of recent servicing
• Any sign of staining, rust streaking, or odour near the tank

When you renew your policy or switch insurers, you'll often be asked directly about your tank's age and type. Providing inaccurate information can void your coverage entirely — so honesty matters here.

What NB insurers typically want to see is a double-wall tank (sometimes called a "tank within a tank") with a secondary containment tray, installed by a licensed technician, and ideally no more than 10-15 years old. Some insurers require a written inspection certificate from a qualified oil burner technician before they'll bind coverage. The NB Department of Environment also has spill reporting requirements — if your tank leaks and you don't report it, you face regulatory penalties on top of remediation costs.

Replacing an indoor single-wall steel tank runs roughly $1,200–$2,500 installed for a standard 200-gallon double-wall unit in the NB market. That's a fraction of what an oil spill cleanup costs — or what you'd pay in higher premiums or denied claims.

This is also a good moment to consider whether oil heat still makes sense for your home. With oil prices volatile and cold-climate heat pumps now rated to -25°C or below, many NB homeowners are using tank replacement as the trigger to convert. NB Power's Total Home Energy Savings Program offers rebates on qualifying heat pump installations, which can meaningfully offset the conversion cost. If you go that route, underground tank decommissioning runs $2,500–$8,000+ and requires a licensed contractor — above-ground tank removal is simpler and cheaper.

The practical next step: Call your insurer directly and ask what their specific requirements are for your tank's age and type. Get it in writing. Then have a licensed oil burner technician inspect the tank — they can give you a written condition report that either satisfies your insurer or confirms it's time for a replacement. If you need a qualified technician or a contractor for tank replacement or heat pump conversion, browse the New Brunswick Construction Network directory to find licensed professionals in your area.

Don't wait for your renewal notice to find out your coverage has lapsed — insurers can and do cancel mid-term when they discover a tank issue during a claim.
