Guarantee

Lifetime Guarantee

Loading... is covered by a lifetime guarantee offering long‑term reassurance to the original owner for the usable life of the product. This refers to the period during which the item can reasonably deliver the performance it was designed for - something that naturally varies depending on how it is used, the conditions it is exposed to and the care it receives. A product used frequently in demanding environments will naturally have a shorter lifespan than one used occasionally and well maintained. For this reason, we assess each case individually rather than applying a fixed timeframe. While this guarantee covers all Terra Nova products, tent and bivi poles are excluded, as they are protected under our dedicated No‑Quibble Alloy Pole Guarantee

Two-Year Pole Guarantee

Every alloy pole supplied with Terra Nova and Wild Country tents or bivis is covered by our No‑Quibble Pole Guarantee. For two years from the date of purchase, we will replace any damaged pole - regardless of the cause, including unforeseen mishaps or accidental damage. This straightforward, hassle‑free policy ensures you can rely on your equipment with confidence, knowing that any tent or bivi pole issue will be resolved quickly so your adventures can continue uninterrupted.
