Q What are the UK Building Regulations requirements for spiral stairs?

A There is a British Standard for spiral staircase design and manufacture - BS5395 Part 2 1984 which defines the overall diameter and the tread size/shape for specific uses. Click on the link above to download a simple table which will tell you what size you'll need for your project. In general terms, if you are accessing a single bedroom as in a loft conversion, this would require a clear tread width of 600mm which would mean the 1600mm diameter. If your spiral will be your main staircase, accessing more than one bedroom or accessing your living room in an "upside-down" house, the clear tread width should be 800mm which would mean a spiral staircase with a diameter of 1830mm to 2000mm or more which would not be available in a kit format.
All staircases need to comply with the Building Regulations Approved Document Part K (see the Advice & Downloads pages) which also requires that, in your home or a property which is likely to be used by children, there should be no gap between the open treads or between the spindles on the balustrade which is more than 100mm to stop children under 5 years old injuring themselves. This is why we offer the riserbars as an accessory as this will put one horizontal bar, matching your staircase, between the open treads to effectively cut the gap down to less than 100mm, and these are available on all staircases. The vertical balustrading spindles on the Fusion and Stilo staircases will also comply with this requirement. It is also required that the balustrading must not be climbable and, for this reason, many Building Control Officers are reluctant to approve the style of balustrading with the horizontal rails or cables, such as the Vogue Spiral or the Vector Linear staircases.

We would always suggest that you discuss this aspect of your chosen staircase with your local Building Control Officer before committing to purchase.

Q What are the UK Building Regulations requirements for linear & modular stairs?

A Linear or Modular stairs come under the Building Regulations Approved Document Part K (see the Advice & Downloads pages for more info) which requires a certain range of tread rises and goings as summarised below:
Maximum tread rise 220mm
Minimum tread going 220mm
Maximum pitch of stair 42º (this would be achieved by a lower tread rise combined with a deeper tread than the minimum requirement)
Maximum headroom 2000mm (for loft access this might be reduced to 1800mm)
Maximum gap between spindles and between open treads 99mm
Height of handrail on staircase 900mm minimum

There is no recommended minimum tread width for linear staircases for domestic use (although in practice it is generally considered that 600mm should be the minimum)
Height of interior balustrading on edge of upper floor stairwell in a domestic property 900mm
Height of exterior balustrading on edge of balcony etc in a domestic property 1100mm
Height of interior balustrading on edge of upper floor in a commercial property 1100mm


Q What are the UK Building Regulations for Spacesaver Stairs?

A Spacesaver or alternate tread staircases are covered in Building Regulations Approved Document Part K (see extract download above). They should only be used to access a single room, such as a bedroom in a loft conversion, and only if there is insufficient space for a standard staircase. They should be in a straight flight, with a maximum tread rise of 220mm, minimum tread going of 220mm and with a handrail on both sides. For the kit spacesaver stairs, this usually means the matching staircase balustrading on one side and a simple wall mounted handrail on the other side, or matching staircase balustrading for the second side if preferred. Because of the format of the treads, the spacesaver staircase will be steeper than a standard staircase, usually about 62º. Again, there is no minimum tread width but it is usually between about 500-600mm. The spacesaver should still try to comply with the 100mm gap rule and riserbars are often chosen for this reason.

We have learnt from experience that it is pretty important, if you are considering using a spacesaver stair, to discuss this with your local Building Control Officer before committing to purchase as their opinions on the suitability of these staircases and their interpretation of the regulations vary enormously around the UK.
