Code-compliant loft staircase design and installation — a critical part of every habitable loft conversion. Compare up to 3 free quotes — no obligation.
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.
Typical cost: basic softwood loft staircase supply and fit £2,000–£5,000. Bespoke hardwood or glass staircase £5,000–£15,000+.

“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.”
“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.”
“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.”
