Reinforced concrete stairs are one of the most durable and structurally capable staircase options available, but they are also one of the more complex elements to price without a full set of project drawings. Costs vary significantly depending on the size and number of flights, the required finish, and the complexity of the formwork involved.
This guide sets out realistic pricing ranges for reinforced concrete staircases in the UK, covers the main factors that affect cost, and explains what to look for when appointing a specialist contractor.
Reinforced Concrete Staircase Cost: Indicative UK Prices
The table below gives indicative pricing for reinforced concrete staircases built in-situ. These are contractor-built, cast-in-place stairs, not precast or prefabricated units.
| Staircase Type | Indicative Cost Range |
|---|---|
| Single residential flight (standard finish) | £3,000 to £6,000 |
| Single residential flight (fair-faced exposed finish) | £5,000 to £9,000 |
| Two-flight residential staircase | £8,000 to £14,000 |
| Commercial stairway (single flight) | £6,000 to £12,000 |
| Multi-flight commercial stairway | £15,000 upwards |
| Basement access stairs | £4,000 to £8,000 |
These figures cover labour and formwork. Structural engineer fees, groundworks, balustrades, handrails, and surface treatments such as tiling or polishing are separate.
All pricing is subject to site conditions and project drawings. Contact us for a detailed quote based on your specific project.
What Affects the Cost of Reinforced Concrete Stairs?
Number of flights and overall scale
The biggest single driver of cost is how many flights the staircase involves and the overall rise and going of each flight. A straightforward single flight between two floors costs considerably less than a multi-flight staircase spanning several levels.
The required finish
A standard shuttered concrete finish suitable for tiling or carpet is significantly cheaper to achieve than a fair-faced exposed concrete finish. Fair-faced work requires precision-engineered formwork, careful pour sequencing, and controlled release of the shutters to leave a smooth, uniform surface. It takes longer and requires more experienced operatives. If you want the concrete surface to be the finished feature, budget accordingly.
Complexity of access and formwork
Stairs in tight or restricted spaces require more complex formwork, which adds time and cost. Curved or helical staircases, or those with awkward geometry, will always cost more than a straight flight. Basement stairs built from a restricted excavation add another layer of complexity.
Whether structural drawings are in place
If you already have structural engineer drawings specifying the reinforcement layout, bar sizes, and concrete specification, a contractor can quote directly from these. If drawings are not in place, you will need to appoint a structural engineer before construction begins. This typically costs between £500 and £2,000 for a residential staircase depending on the complexity.
Location
Most specialist reinforced concrete contractors operate within a defined regional area. Working within that area keeps mobilisation costs down. Projects at the edge of or outside a contractor’s usual patch will typically carry a travel or mobilisation premium.
In-Situ vs Precast Concrete Stairs: Does It Affect Price?
Precast concrete stairs are manufactured off-site in a factory and delivered as finished units. They can be cheaper for straightforward, standard configurations. However, they are limited in terms of geometry, finish options, and the ability to integrate with complex structural details.
In-situ reinforced concrete stairs are cast in place using formwork. They cost more but offer full flexibility on size, shape, reinforcement, finish, and structural integration. For basement conversions, architectural projects, commercial buildings, and anything bespoke, in-situ is almost always the right choice.
If you are comparing quotes for both, make sure you are comparing like for like. A precast unit price rarely includes installation, cranage, or the structural connections required to integrate it with the surrounding frame.
What is Included in a Concrete Stairs Quote?
A detailed quote from a specialist reinforced concrete contractor should include:
- Supply and erection of formwork and shuttering
- Steel fixing to the structural engineer’s specification
- Concrete pour and compaction
- Striking and removal of formwork after the curing period
- Any remedial work to the concrete surface
It will not typically include the structural engineer’s design, balustrades, handrails, any surface finish applied after striking (tiles, screed, polish), or connection to adjacent structures if this falls within another trade’s scope.
Always ask your contractor to confirm exactly what is and is not included before accepting a quote.
How Long Does It Take to Build Reinforced Concrete Stairs?
A single residential flight typically takes three to five working days from erecting the formwork through to striking. There is then a curing period before the stair can be loaded, usually a minimum of seven to fourteen days depending on the concrete specification and conditions.
Multi-flight or architecturally finished stairs take longer. A realistic programme for a two-flight commercial staircase, including curing, is typically three to four weeks.
Your contractor should provide a clear programme as part of the quote so you can sequence it within your wider build programme.
How to Get an Accurate Quote
The most accurate quotes come from projects where structural drawings are already in place. If you are at an early stage and drawings are not yet ready, a good contractor will be able to provide a budget figure based on a site visit and a description of the project, with a confirmed quote to follow once drawings are available.
For any project across Bristol, Bath, Gloucestershire, and the wider South West, we are happy to visit site, review your drawings, and provide a detailed written quotation.
Frequently Asked Questions
A standard single flight for a residential property typically costs between £3,000 and £6,000, depending on size and finish. Fair-faced exposed concrete finishes start from around £5,000 for a single flight. These figures cover labour and formwork but not structural engineer fees, balustrades, or surface treatments.
For a comparable specification, reinforced concrete stairs are generally more expensive than timber but competitive with structural steel staircases, particularly on commercial projects. Concrete stairs offer significantly greater durability, fire resistance, and acoustic performance, and require no ongoing maintenance once built.
Yes. Reinforced concrete staircases must be designed by a structural engineer to calculate the reinforcement layout and concrete specification. If you do not already have drawings, you will need to appoint an engineer before construction. We can recommend structural engineers if needed.
Reinforced concrete stairs are essentially permanent. Properly designed and built, they require no maintenance and will outlast almost any other staircase material. They will not warp, rot, corrode, or require replacement.
Yes. Basement access stairs are a common application for in-situ reinforced concrete. The restricted working environment of a basement excavation adds some complexity to the formwork, but it is standard work for an experienced specialist contractor.
