About Northern Polytunnels

---

Northern Polytunnels is a leading UK manufacturer of high-quality polytunnels, growing structures, and steel-framed shelters. Based in Lancashire and established in 1969, we design and produce everything in-house, ensuring exceptional strength, durability, and value. Our products are used by gardeners, commercial growers, schools, community projects, and even the National Trust and RHS.

Domestic Polytunnels for Gardens and Allotments.

Our EasyBuild polytunnels are ideal for home growers, whether you’re growing on an allotment, in a back garden, or in a smallholding. With widths from 2. 5m to 4. 5m and plenty of customisation options, these tunnels are easy to install and built to last. Unlike timber-framed alternatives, our steel-framed tunnels won’t rot – offering a long-term, low-maintenance growing solution.

Commercial Polytunnels for Professional Growers.

Our EnviroPro range is trusted by commercial horticultural businesses, nurseries, schools, and organisations such as the RHS and National Trust. These larger tunnels are engineered to meet the demands of professional growers, with wider spans, greater internal clearance, and custom configurations to suit your crop and workflow needs. We also supply accessories including crop bars, side vents, and polythene options.

Industrial and Storage Structures.

In addition to growing tunnels, we manufacture a wide range of industrial shelters and storage structures. From mobile field shelters and covered workspaces to robust machinery storage and vehicle bays, our steel-framed solutions provide reliable protection in challenging outdoor environments. All are built to British Standards using materials that stand up to heavy use and weather exposure.
