No concrete, no excavation, and no damage to your garden. We offer DIY supply, trade supply, and professional installation, so whatever your project needs, we've got it covered.

We Fit - You Fit

Screw Foundations UK offers a range of self-installation options for both the DIY enthusiast and trade customers and installers. Our ground screw calculator will help you work out how many ground screws you need for your project.

If you are pushed for time or don’t want to take on the foundation work yourself, we can take the load off with our nationwide installation service. If your project is subject to building regulations and requires building control approval, we offer a commercial installation service that includes compression load testing and a detailed report.

The versatile solution

Building on gradients? Ground screws for garden rooms make easy work of building on a slope or other difficult plots. The ground screws can be carried to the site by hand, eliminating access issues. You don’t need to destroy natural habitat or cut down trees. And you won’t risk affecting waterways. Overall, ground screws are the versatile choice for a wide range of projects, including those more difficult installations.

For garden room companies and trade installers

If you’re a garden room company installing foundations regularly, we supply trade volumes with next-working-day delivery from one of the UK’s largest stocks. We also offer dedicated technical support to help you specify the right product for each job.

For builds that require building control sign-off – such as SIPs panel construction or larger annexe-style garden rooms – we offer helical screw pile foundations with:

  • Machine installation using excavators with calibrated torque monitoring
  • Comprehensive torque pile logs recording installation torque, depth, and performance data for every pile
  • Certified load capacity reports through deep foundation software
  • Stock sizes from 76R to 140R, plus bespoke manufacturing

This gives your customers the engineering documentation they need and speeds up the approval process – without you having to coordinate a separate piling contractor.
