Loft Staircase

A proper loft staircase is a building regulations requirement for any habitable loft room — it must meet minimum tread, riser and headroom requirements to gain sign-off. The staircase also defines the layout of the floor below it, making it a critical design decision that affects both the loft and the existing bedroom.

Space-saving staircase designs (alternating tread stairs, space-saver stairs) can be used where headroom or floor plan constraints make a standard staircase difficult. Getting quotes from your loft conversion specialist and potentially a specialist staircase company helps find the right solution.

What’s involved

  • Measuring and designing the staircase route to meet building regulations headroom requirements
  • Opening the ceiling and creating the landing platform at loft level
  • Fitting the string, treads and risers to the calculated pitch and rise
  • Fitting a handrail and spindles to building regs specification
  • Making good the ceiling and walls around the staircase opening on the floor below

Typical costs

Typical cost: basic softwood loft staircase supply and fit £2,000–£5,000. Bespoke hardwood or glass staircase £5,000–£15,000+.

FAQs — Loft Staircase

What are the building regulations requirements for a loft staircase?
The minimum clear headroom above the staircase is 2.0m (1.8m for a space-saver stair). Maximum rise per step is 220mm, minimum going 220mm. Handrails must be provided on at least one side. Your specialist and building control inspector will confirm compliance.
What is a space-saver staircase?
A space-saver or alternating tread stair uses paddle-shaped treads that alternate left and right, allowing a steeper pitch in a smaller footprint. They are approved under building regulations for loft access where space is severely restricted, but are less comfortable to use than a conventional stair.
Where does the loft staircase usually go?
The loft staircase typically takes space from the landing or a bedroom on the floor below. The exact location is determined at survey stage to minimise disruption to existing rooms while meeting headroom requirements.
Can I have a spiral staircase to my loft?
Spiral staircases are generally not accepted by building control for primary access to a habitable room as they do not meet the standard rise/going requirements. A bespoke straight or quarter-turn staircase is the typical solution.
Does the staircase need a fire door at the bottom?
Yes — building regulations require a fire door at the base of the loft staircase (or at the loft level) as part of the fire escape strategy for the new habitable room. Your specialist will specify the correct door.
What customers say
★★★★★ 4.9 / 5 from verified customers
★★★★★

“We had a rear dormer conversion done last summer — extra bedroom and en-suite for our teenage daughter. Got three quotes through this site, saved around £4,000 compared to the first firm we spoke to. The specialist handled planning permission and building regs start to finish. Highly recommend.”

Sarah M. Surrey
★★★★★

“Hip-to-gable conversion on our 1930s semi. I was nervous about the planning application but the specialist I found here had done dozens in our street and knew exactly what to submit. Project came in on time at 10 weeks. The new master bedroom is brilliant.”

James R. Leeds
★★★★★

“L-shaped dormer on our Victorian terrace — created two rooms and a bathroom from what was a completely unusable loft. The comparison process gave me confidence I was paying a fair price. Building control sign-off came through with no issues. Absolutely transformed the house.”
