About

Northern Polytunnels is one of the UK’s leading manufacturers of polytunnels and steel-framed structures, trusted by growers since 1969. Based in Colne, Lancashire, the company designs, manufactures, and supplies a full range of growing structures for domestic gardeners, commercial growers, schools, community gardens, and the horticultural trade.

From small allotment tunnels to large-scale commercial builds, Northern Polytunnels has built a reputation for strength, reliability, and practical design. All products are manufactured in-house using high-grade galvanised steel, ensuring consistency and quality across every structure. The company’s in-house design and production teams work closely with customers to provide practical, long-lasting solutions tailored to a wide range of growing environments.

Northern Polytunnels' domestic range is led by the EasyBuild Polytunnel, a robust, self-assembly tunnel designed for home growers who want the benefits of a commercial-grade structure without the complexity. EasyBuild tunnels are available in a wide range of sizes (2.5m -4.5m) and configurations, with features such as side ventilation, crop bars, irrigation, and timber-free frames that prevent rot and reduce long-term maintenance.

For commercial customers, the EnviroPro range offers professional-grade, single-span tunnels manufactured to meet BSI structural loading standards. These tunnels are built using 80 x 40mm flat-sided oval steel tubing as standard, offering superior rigidity and wind resistance, even in exposed environments. The range is fully customisable and suitable for commercial horticulture, market gardening, community agriculture, and research applications.

In addition to growing structures, Northern Polytunnels also supplies a range of industrial shelters and steel-framed buildings for use as workshops, machinery storage, livestock cover, and weatherproof operational space. These structures offer the same strength, durability, and British-made reliability as the company’s horticultural products.

What sets Northern Polytunnels apart is its commitment to in-house manufacturing, knowledgeable support, and decades of experience serving UK horticulturalists. Every structure is designed and built in Britain, backed by a team that understands the needs of the agricultural and horticultural sectors. The company is proud to supply organisations such as the RHS, National Trust, David Austin Roses, and thousands of commercial and domestic growers across the UK.

Northern Polytunnels also continues to invest in tools and services that make tunnel planning and ordering easier. Their online product configurators allow customers to design and order tailored structures directly from the website, with clear pricing, specifications, and optional extras all in one place.

As a long-standing British manufacturer, Northern Polytunnels remains focused on quality, customer service, and continuous improvement, providing growers of all scales with the structures they need to grow better, for longer.
