Buy British Polytunnels - direct from the manufacturer

You can purchase from these polytunnels in complete confidence. Built in purpose-built workshops to comply with the highest UK and EU standards. And we only use top quality materials.

Market gardeners throughout the UK use our polytunnels. And of course, we use our own tunnels here in Norfolk. Now hobby gardeners, allotment owners and small holders can own a commercial grade polytunnel. Order from Oakland Gardens for an affordable product used by professionals.

Our polytunnels are made to endure the very worst of the British weather. They’ll withstand the strongest gales and storms. This is what makes our polytunnels different from the cheap imported tunnels you may find elsewhere on the internet. Made from inferior materials imported polytunnels will easily tear and buckle and will not last long once the wind gets at them.

By contrast our polytunnels are used by growers in the most windswept areas of the UK including the Scottish Islands and Highlands, Welsh mountains and English moors.

Guaranteed quality

Buy from us and your polytunnel will literally last for decades. We manufacture our frames from high tensile steel. Steel which has a life expectancy of over 50 years. We even use horticultural nursery grade polythene for our covers. We absolutely guaranteed them for five years.

Commercial grade polytunnels for everyone

Whether you’re a hobbyist or professional grower you won’t find a better-quality product at a lower price. Buy now for fast delivery anywhere in the UK.
