How Much Does It Cost to Install a Staircase?
£2,000 – £9,000
supply and fit
Installing a staircase costs between £2,000 and £9,000 supply and fit, depending on the style, material, and complexity of the installation. A standard straight staircase in softwood is at the lower end; an oak open-tread staircase with glass balustrade panels or a bespoke curved staircase costs significantly more.

What affects the price?
Staircase style - a standard straight staircase costs £2,000-£4,000 installed; an L-shaped or quarter-turn staircase costs £3,000-£6,000; a bespoke design costs £6,000-£15,000+
Material - softwood (pine) is cheapest; oak costs significantly more; glass panels for the balustrade add £500-£2,000
Structural opening - if the staircase opening in the floor needs widening or structural work is required, this adds cost
Building regulations - staircases must comply with Part K of Building Regulations for rise, going, and balustrade height
Labour vs materials
Installing a staircase typically takes two to three days for an experienced joiner. Labour accounts for 30-40% of the total cost for a standard staircase; the staircase unit itself makes up the majority.
Repair or replace?
If a staircase is structurally sound but creaking, loose newel posts or baluster repairs can be carried out for £100-£500. If the treads are worn through, the string is cracked, or the staircase is non-compliant with current Building Regulations, replacement is the safer option.
