I ordered a beautiful marquee from these guys a couple of years back. Cannot fault the customer service nor the quality of their products. Highly recommended.
Great products and even better customer service. I've compared prices, quality and service, and none do better than Dancover
I ordered a marquee from Dancover, plus some extra items like lighting and carpet. The service was second to none. Wholehartedly recommend these guys. By the way, the marquee looks fab.

How to make the most of your polytunnel greenhouse
Please note that our range of polytunnel greenhouses are intended as seasonal structures only to be used from early spring until late summer/early autumn depending on the weather. The reason for this limitation is that a polytunnel greenhouse is a light structure – as opposed to, e.g. our polycarbonate greenhouses with strong aluminium frames. Our polytunnel greenhouses are not made to withstand heavy wind, strong rain or snow. Please read our Safety Advice before setting up the greenhouse.
Ground skirt for securing your polytunnel greenhouse
Please note that it is important that you secure your polytunnel greenhouse when you set it up. All our polytunnel greenhouses have a surplus of cover along the bottom edge at the ground – even the ones where you cut the cover yourself! This surplus is called the ground skirt, and you need to either bury this ground skirt or place heavy objects on it to weigh down the greenhouse for safety reasons.
Dancover expert tip: Polytunnel greenhouses are great for growing a variety of different plants. Remember to water frequently, ventilate as much as possible and harvest your crops regularly! It is extremely important that you keep the cover on the polytunnel greenhouse stretched and taut at all times. Otherwise, a risk emerges that during a rainfall water pile up on the roof of your greenhouse, which may cause the greenhouse to collapse.
