Polytunnel Construction Service
Our three construction teams are almost fully booked up to January 2027. We have a very limited number of vacant dates prior to this, some of which are location dependant. Please contact us to discuss available dates.
We’re proud to offer the First Tunnels’ Construction Service team. We have three teams of dedicated polytunnel construction experts who have been there and built that. With over 200 years experience between them, they have a wealth of polytunnel construction knowledge and are more than happy to share tips and advice with any of our customers.
Many of the team have been quite literally ‘hands on’ developing the First Tunnels vast array of polytunnel erectors videos and in depth downloadable instructions.
Our upcoming projects
Our polytunnel construction service teams will travel to your site and construct your polytunnel. Depending upon the size of polytunnel specified, most domestic sized installations can be done within a day. Commercial constructions vary depending upon size and complexity.

What Our Customers Think Of Our Polytunnel Construction Service
How long does it take to build a polytunnel?
Putting up a polytunnel is like the biggest piece of flat pack furniture you could imagine and although it might look and sound daunting, erecting a polytunnel should actually be a straight forward, rewarding experience. We appreciate that putting anything together you’re not used to can initially feel a tad overwhelming and we are conscious that there are many factors and variables that influence the work involved when constructing a Polytunnel. Digging conditions, weather, the way it’s secured to the ground, DIY capabilities and size of Polytunnel, all contribute to the length of time it can take, so it would be wrong for us to advise a specific timescale. Sorry, there is no definite answer….For example a 10ft x 20ft Base Rail version Polytunnel would require 10 holes digging where as a 30ft x 90ft long would require 32 holes – and depending on digging conditions the 10 difficult holes could take longer than 32 easy holes.
It’s definitely not the sort of job you can complete on a lazy Sunday afternoon but building your own polytunnel can save you hundreds of pounds in construction costs and you can stand back and say “I built that!” All you need are some basic DIY skills, decent weather conditions and some willing helpers. Why not rope in friends and family to help make a party of it with the promise of free vegetables once your polytunnel is up and running!
The more preparation you do, the more likely the project will proceed smoothly without surprises. Ask to see a copy of the instruction manual before taking the plunge so you can check how straightforward they are to follow and learn exactly what’s involved – our Construction Guides can be downloaded free of charge. Getting all your tools together is a must. There’s nothing worse than getting stuck in and then realising your battery operated drill needs charging or forgetting your ladders are out on loan. Make the process as easy as you can by preparing your site ahead of time. Remove all vegetation, mark out the basic shape of the polytunnel and even do a “trial dig” of the proposed site. This way you will have a good idea if the ground is going to be easy or problematic and plan accordingly. It might even mean considering hiring a mini digger or extra muscle power!
When the kit arrives, check that all components are there, and read the instructions carefully….again! How many times are we told to read the instructions before we start to use something but skip bits because we’re in a hurry? You’ll find it extremely beneficial to familiarise yourself with the construction process and component/part names. Watch our handy step by step Construction Videos as this will help save you time when the “big day” arrives.
Although it is hard to predict the weather…. a still, dry day is always best – tempers may fray trying to install the Polytunnel if the weather isn’t favourable. You’ll also risk setting sail to the most expensive kite you’ll ever fly, if you’re trying to put a polytunnel up in anything but the calmest of conditions. Don’t forget you are literally putting together a small building (quite often the size of a swimming pool). A substantial piece of kit that is going to last many, many years and pay for itself in fresh fruit and veggies time and time again. Now that’s nothing to be sniffed at.
Can a polytunnel be built on a slope?
Yes we can accommodate a slope providing it isn’t too excessive. If the slope is along its width then foundation tubes on the lower side can be protruding out of the ground by a maximum of 15cm. If the slope is more than this then you would need to have extended foundation tubes to ensure that there is enough tube fixed into the ground.
For slopes along the length, the Polytunnel can be constructed as normal ensuring that the hoops are kept vertical.
What site preparation is required before installation?
The site should be clear of obstructions and reasonably level from side to side. Small variations in level can usually be accommodated using the foundation tubes. Any major levelling or groundwork should be completed prior to installation.
How long will it take to construct a polytunnel?
Installation time depends on the size and specification of the polytunnel, but most standard tunnels are constructed within one day. Larger or more complex structures may take longer.
Do you construct all year round?
Yes, we construct polytunnels all year round. Installation can take place in most weather conditions; however, extreme weather such as high winds or heavy snow cause delays for safety and practical reasons. We will always assess conditions in advance and advise if it is necessary to reschedule to ensure a safe and high-quality installation.
How much does does construction cost?
The cost of polytunnel construction varies depending on several factors, including the size and specification of the tunnel.
To get an accurate price, please contact us with your site details, desired polytunnel size and configuration, and any specific requirements you have. We’ll be happy to provide a comprehensive quote.
Do I need planning permission?
Planning requirements vary depending on location and intended use. We recommend checking with your local planning authority before installation, especially for larger or permanent structures.
Do I need to be present during construction?
It is helpful, but not essential, as long as we have clear access to the site and any specific instructions beforehand.
