| Material | Cost Premium | Durability | Typical Finish | Notes |
|---|---|---|---|---|
| Softwood (pine/spruce) | Base price | Moderate | Painted or stained | Most affordable |
| Oak (solid) | +80–150% | Excellent | Oiled, lacquered or stained | Most popular hardwood |
| Ash / Beech | +50–100% | Excellent | Oiled or lacquered | Similar to oak |
| Walnut (solid) | +150–250% | Excellent | Oiled natural | Premium hardwood |
| Steel / mild steel | +100–200% | Very high | Powder-coated | Industrial / modern look |
| Toughened glass treads | +200–400% | High | Clear / frosted | Specialist install req. |
| Concrete (cast in-situ) | +300–600% | Permanent | Polished / tiled | Commercial or bespoke |
Cost premiums are relative to a basic straight softwood staircase. Mixed-material staircases (e.g. steel frame with oak treads) are priced between the two material costs.
| Balustrade Type | Supply Only (per m) | Supply & Fit (per m) | Full Flight Est. | Notes |
|---|---|---|---|---|
| Wooden spindles (softwood) | £40–£70/m | £80–£150/m | £400–£900 | Most common |

| Rope / cable balustrade | £100–£200/m | £200–£380/m | £1,000–£2,300 | Industrial / nautical |
Full flight estimates assume 5m of balustrade for a standard 13-step staircase. Prices exclude newel posts (£80–£400 each) and handrail brackets. Building Regs require balusters no more than 100mm apart.

Tips for a successful staircase
Check Building Regulations
Any new staircase must comply with Building Regulations Part K. This sets minimum rise (max 220mm), going (min 220mm), headroom (min 2m), and balustrade spacing (max 100mm gap). Your installer should certify compliance — if not, ask for evidence.
Get 3 Quotes
Staircase costs vary by 40–60% between joiners for identical work. Always get at least 3 written quotes specifying the same materials, dimensions and specification. Check the joiner’s previous work and ask for references before committing.
Measure Carefully
Accurate rise-and-going measurements are critical. Measure total floor-to-floor height (not just ceiling height), account for floor finishes, and check headroom at the lowest point. Errors at this stage are costly to correct after manufacture.
Consider Access
Long straight staircases can be difficult to get through front doors or around corners. Pre-fabricated staircases may need to be assembled in situ. Spiral staircase kits arrive in sections. Always confirm your joiner has considered access before ordering.
Think About Maintenance
Softwood treads mark and dent more easily than hardwood but are cheaper to replace. Oak is harder and easier to maintain long-term. Glass balustrades show fingerprints. Carpet hides wear but needs periodic replacement. Consider your lifestyle before choosing materials.
Staircase costs FAQ
Everything you need to know about staircase costs, types and installation in the UK.
A new straight staircase in the UK typically costs £800–£2,500 for softwood (supply and fit), £1,500–£4,500 for solid oak, and £3,500–£12,000+ for floating or feature designs. Spiral staircases cost £1,500–£9,000 depending on material. Prices vary significantly by region — London and the South East are typically 25–42% above the national average.
Yes. Replacing or altering a staircase must comply with Building Regulations Part K (Protection from Falling, Collision and Impact). This covers maximum rise (220mm), minimum going (220mm), minimum headroom (2m), and maximum balustrade gap (100mm). For a like-for-like replacement, you may use a competent person scheme rather than submitting a full Building Regulations application. Always check with your local authority.
A straight staircase replacement typically takes 1–3 days for an experienced joiner, including removing the old staircase. L-shaped and U-shaped designs take 2–4 days. Spiral staircases take 1–2 days for kit assembly. Bespoke floating or feature staircases may take 3–7 days on site, plus 4–12 weeks for manufacture. Timing also depends on plastering, decorating and flooring work required around the staircase.
The most affordable option is a straight softwood (pine) staircase from a prefabricated stock design, which costs £800–£1,800 supply and fit. If you already have a structurally sound staircase, refurbishment — sanding and painting treads, replacing spindles, fitting a new handrail — is significantly cheaper than full replacement, typically costing £300–£1,500 depending on scope.
A steel spiral staircase kit costs £800–£2,200 supply only, or £1,500–£3,500 supply and fit. Cast iron designs cost £2,000–£6,000. A bespoke oak or glass spiral staircase can cost £4,000–£15,000+. Spiral staircases are popular for loft conversions due to their compact footprint — they typically require only 1.5–1.8m² of floor space compared to 5–7m² for a straight staircase.
Floating (open tread) staircases are significantly more expensive — typically £3,500–£12,000 compared to £800–£4,500 for a traditional staircase. However, they create a dramatic architectural feature, allow light to pass through the staircase, and can make a hallway feel larger. They require a structurally sound wall or steel beam for fixing and specialist installation. They’re most cost-effective in open-plan spaces where they become a design focal point.
