Northern Polytunnels has announced the return of its annual Black November Sale, offering customers a month of web-exclusive savings on its British-made growing structures and accessories. The event runs from 1st to 30th November, with discounts of up to 50% across selected products.
Unlike typical weekend flash sales, Black November gives growers and horticultural businesses the chance to plan ahead and invest in reliable, long-lasting equipment, all designed and manufactured here in the UK.
Built in Britain, Trusted Nationwide
Since 1969, Northern Polytunnels has been manufacturing polytunnels and protective structures at its Lancashire facility, supplying everyone from hobby gardeners to major commercial growers and respected organisations including the RHS and National Trust.
Each tunnel is engineered to meet British Standards for structural strength and weather resistance, using materials and manufacturing expertise developed over five decades of production.
The Black November event includes savings of:
10% off EasyBuild & EnviroPro Polytunnels (use code BN10 at checkout)
10% off aluminium benching systems
50% off circulation fans
40% off parts & accessories
20% off water collection and irrigation kits
All offers are available through the Northern Polytunnels website throughout November, with discounts applied automatically at checkout (except for EasyBuild and EnviroPro, which require a coupon code).
Designed for Real-World Use
Northern Polytunnels’ manufacturing philosophy has always been simple: build stronger structures that last longer. By maintaining full control of design and production in-house, the company continues to deliver products that withstand the demands of both the British climate and commercial use.
This commitment to durability has earned the business its place among Britain’s most trusted horticultural manufacturers, and it’s that same commitment that underpins the Black November event.
“Our goal isn’t just to discount products; it’s to help growers invest in the right equipment at the right time,” says the Northern Polytunnels team. “We’re proud to build everything here in Lancashire, and this event is a way to thank customers old and new for choosing British manufacturing.”
