How much does a new staircase cost? In the UK, a basic straight softwood staircase costs between £450 and £600 for the materials, plus £400 to £600 for professional carpenter installation. Upgrading to hardwood (like oak), adding glass balustrades, or installing complex winder designs will push the total cost between £3,000 and £5,000 fully fitted.
Changing a staircase is major structural work that completely transforms your hallway. I have installed and ripped out my fair share of staircases over the years, and I always see homeowners get caught out by the hidden fees. You might see a softwood staircase advertised online for £450, but that does not include the carpenter’s day rate, the plasterer needed to fix the damaged stairwell walls, or the cost of Building Control sign-off. Here is a realistic cost breakdown to help you budget correctly and avoid nasty surprises.
Average UK Staircase Costs (£)
To give you a realistic idea of what you will spend, here are the average base costs for common staircase configurations.
| Staircase Type | Starting Material Cost (excl. fitting) | Total Estimated Cost (Fully Fitted) |
| Straight Softwood | £450 – £600 | £850 – £1,200 |
| Straight Hardwood (Oak) | £1,200 – £1,800 | £1,800 – £2,600 |
| Single / Double Winder | £600 – £900 | £1,200 – £1,800 |
| Bespoke Hardwood & Glass | £3,000 – £5,000 | £4,500 – £7,000+ |
| Bespoke Metalwork | £6,000 – £10,000 | £8,000 – £15,000 |
Material Costs: Softwood vs. Oak vs. Metal
The deciding factor in your final price is the material you choose. Softwood (usually pine) is the most common and cost-effective option. It is easy to work with and perfect if you plan to paint your stairs.
Hardwoods like oak and ash offer a premium, contemporary finish but come at a significantly higher cost. If you want a truly modern look incorporating architectural glass or bespoke metalwork, you are entering the top tier of pricing.
Pro-Tip: The “Tread vs. Riser” Material Hack
If you intend to carpet your stairs or install a central runner, do not waste money buying a full solid oak staircase. Order cheap MDF or plywood for the treads and risers (the horizontal and vertical sections that will be hidden by the carpet), and only pay for premium oak on the visible handrails and newel posts. This simple hack saves hundreds of pounds while still delivering a high-end look.
Labour Costs: Hiring a Carpenter vs. DIY
It is possible to fit a staircase as a DIY project, but it is not easy. A staircase must hold tremendous weight safely. I strongly advise hiring a professional carpenter unless you are a highly experienced DIYer.
A qualified UK carpenter will charge roughly £200 to £250 per day. A simple, straight staircase will usually take two days to fit, bringing your labour costs to between £400 and £500. Complex winder staircases or those requiring structural alterations to the floor joists will take longer and push your labour bill higher. If you are refurbishing an old staircase rather than replacing it completely, you will likely need to invest in the best sander for skirting boards to reach into tight stair corners efficiently.
UK Building Regulations (Part K) You Must Follow
When replacing a staircase, you must adhere strictly to UK Building Regulations Part K. This is not just bureaucratic red tape; it ensures your stairs are safe to use. You cannot simply build whatever fits the space.
The maximum pitch (steepness) allowed for a domestic staircase is 42 degrees. The ‘going’ (the flat tread depth) must be a minimum of 220mm, and the ‘rise’ (the vertical height between treads) must be between 150mm and 220mm. Finally, you need a minimum headroom clearance of 2 metres across the entire flight. You can read the official Building Regulations Part K guidelines for full details.
If your design requires structural alterations to the floor joists to achieve this 2-metre headroom, you must apply for Building Control approval, which typically costs an additional £200 to £300.
The Hidden Costs: Plastering, Decorating, and Carpets
The biggest shock for homeowners is the knock-on cost of ripping out an old staircase. You are not just paying for timber; you are paying to fix the mess left behind.
- Plastering: Removing the old stringers will tear chunks of plaster off your walls. Budget around £250 to £400 for a local plasterer to skim the stairwell walls.
- Skip Hire: Old timber staircases are bulky and heavy. You will need to budget £250 to £300 for a skip to safely dispose of the old structure.
- Structural Engineers: If you need to widen the stairwell opening in the floor above to accommodate a new layout, you must hire a structural engineer to calculate the load adjustments, costing roughly £250 to £400.
- Flooring: Do not forget to factor in the cost of new carpets or runners. If you are leaving your stairs bare timber and continuing the look onto your landings, you will need to calculate your wood flooring installation costs.

FAQs
Do I need planning permission to replace a staircase?
Usually, no. Replacing an existing staircase internally falls under Permitted Development and does not require planning permission. However, you must always ensure the new staircase complies with Building Regulations (Part K) and get Building Control sign-off if making structural changes to floor joists.
Can I move my staircase to a different room?
Yes, but it is a major structural undertaking. Moving a staircase requires cutting a new opening in the floor above, reinforcing the floor joists, and ensuring you still meet fire escape regulations. This will significantly increase your labour and structural engineer costs.
