We have been leading innovation in Commercial Polytunnel design and manufacture since 1969.

Northern Polytunnels (NP Structures Ltd.) are the largest manufacturer of polythene and PVC clad structures in the UK. We have worked with some of the UK’s leading producers including P.J. Stirling Farms and Ball Colegrave and have covered 1000's acres with our high-quality products.

Single Span Polytunnel - Our in-house design team have made a strong and durable structure that offers internal flexibility for large scale growing among many other versatile uses. 

Multi-Span Polytunnels make the best use of your available space as there are no redundant areas between each bay. Typically around 20% higher at the apex, but due to the extra height being in the 'leg' they have approximately 25%-30% greater air volume, providing a more harmonised environment that is less susceptible to sudden temperature fluctuations.

Shade Structures - Working closely with commercial growers we are able to design and manufacture state of the art permanent polytunnel shade structures to suit their requirements. Made from the finest commercial materials all our shade structures provide semi-shading, protection from direct sunlight and allow free air circulation creating optimum growing conditions.

Canopy Structures are based on the multi-span structure, they incorporate wide gutters on support posts fitted to both sides of the framework.

The standard widths are available in: 6.4m (21ft), and 8m (26ft)

Insulated Tunnels - Twin-skinned polythene clad structures can reduce the rate of heat loss by a further 30%-40% compared to single-skinned polythene structures.

We stock a wide range of parts that are of the highest quality. From Polythene Covers to Staging and from Irrigation to Trolley Tracks and Pathways

From large scale hobbyists and garden centres to butterfly houses and dog training areas, we have over 50 years of experience designing, manufacturing and constructing bespoke commercial structures for various growing industries and many others. Using the finest commercial-grade materials made within the heart of the U.K., all our commercial structures are fit for purpose and designed to withstand the most extreme weather conditions, providing ultimate protection to your crops and plants or whatever else you want to protect.

Customer Reviews

Only the best!

Really great quality tunnels with much more substantial tubes than many competitors. Lots of options available to suit all requirements. Great customer service. Have purchased two tunnels so far.

Fully satisfied

I brought my entire poly tunnel from northern polytunnels and will probably be buying another bigger one at some point off them. Very happy!
