In addition to this, the staircase is CE approved to EN 1090 (EU Construction Production Regulation) for extra safety and peace of mind.
    Some of our competitors sacrifice safety for a cheaper build quality something we will never do! Weaker treads make the staircase less stable. Furthermore, alternatives arent approved meaning you dont fully know what you are getting.

  • F.A.Q.

    Is this staircase compliant with building regulations?

    Yes it is, providing you select the upgrade to 4 balusters per tread this allows it to conform to the 100mm gap rule. In addition, child riser bars may be necessary. We always recommend that you check what you need with your building inspector too, before purchasing.

    What are the differences between this one and the Deluxe Spiral?

    There are numerous differences, the main one being that the treads are larger, made of premium wood and stronger. Everything about this staircase is just a bit more substantial, enabling you to really feel the difference when you are climbing. In addition, it will suit floor to ceiling heights of up to 3.5m.

    It says 10 working days to delivery on the site, how will I know which day it will arrive?

    Our delivery company will contact you when it is ready for dispatch to make sure someone is in and able to accept delivery. The delivery timescale we provide is the maximum time you will have to wait, the majority of these orders are fulfilled much quicker than this.

    I want to fit the staircase into a round hole in the ceiling, as opposed to a square one. Is this possible?

    Yes this is fine. The top landing tread can be cut to accommodate a round hole. Please see the installation instructions for a guide on how to do this.

    Do you install these staircases?

    We do not unfortunately. However, we provide detailed written and illustrated instructions along with an installation video on our website, to make it easy. If you have any questions regarding installation, just give our customer service team a call.

We check our competitors' prices daily to ensure you get the best deal. All prices include free delivery to the mainland UK - others hide delivery costs until the last moment. We Will Not Be Beaten On Price!
