About Northern Polytunnels
Northern Polytunnels is a UK manufacturer of premium polytunnels, supplying gardeners, allotment holders and commercial growers across the UK and beyond. Founded in 1969, we’ve spent over five decades refining the design and manufacture of polytunnel structures that are built to last.
Unlike many polytunnels on the market, our structures are engineered using heavy-gauge galvanised steel frames with no timber components, eliminating rot and significantly extending the working life of the tunnel. Every design decision is made with longevity, strength and real-world growing conditions in mind.
From compact garden polytunnels to large-scale commercial growing systems, our range is designed to give growers reliable control over their environment, season after season. All Northern Polytunnels are manufactured to meet relevant British Standards and are trusted by organisations including the RHS, the National Trust and professional growers nationwide.
What Makes Us Different
Made in Britain
We manufacture every structure in our own facility using top-grade steel and high-spec polythene. No cutting corners, no cheap imports.
Built to Last
We don’t believe in disposable structures. Our polytunnels are engineered with the strongest flat-sided-oval steel hoops, and galvanised to withstand the harshest weather. No timber. No rot. No nonsense.
Designed for Real Growers
Whether you’re starting your first veg patch or running a commercial nursery, our polytunnels are easy to build, easy to customise, and seriously robust.
