Important - please read before purchase
Fixed Ladders, Space Savers, Spirals and Loft Stairs are covered in the building regulations and we recommend you confirm with the Local Building Control Department regarding their suitability for any project prior to specifying.
Therefore it is your responsibility to ensure that any local authority approvals necessary have been obtained. This will vary according to your application and we advise you to always check before going ahead with a purchase.
Many of our products have been widely used in the past in conjunction with Building Control, but the interpretation of the requirements for any particular situation remains solely with your Local Building Control Department.
