The Cost of a Spiral Staircase in 2026

In summary, a kit system will cost £1500-£3000 and a custom spiral stair will cost £6000-£10000 plus.

In 2026, spiral staircases remain a popular choice for self-builders and refurbishers who are looking for a staircase that is both space saving and architectural in style, yet still easy to use. Not only do they have a small footprint, they also only require a comparatively small opening in the floor they are ascending to. The cost of a spiral staircase can range significantly from off the shelf kit systems to fully bespoke designs made from premium materials such as walnut, glass and stainless steel.

Spiral Stair options

those on a tight budget, a kit spiral staircase is the most cost-effective option. Although not made to measure, they are supplied in standard sizes and can be adjusted to reach a specific floor height. They can also be installed by both builders and DIY enthusiasts alike. A basic all metal spiral staircase kit will typically start from £1500 to £2,000, making them a good entry‑level choice. A mid-specification spiral kit will be between £2,000 and £3,000. At this price point, many suppliers offer timber treads which make for a warmer aesthetic and are more comfortable to use. For a high specification kit system, you’ll be able to add a timber handrail and will also be able to access a much wider range of material finishes but expect to pay £3,000 or more.

 Kit Spiral Staircases

A Kit spiral staircase is ideal for use as a secondary access to a loft space, or in a location where the staircase will not be on show. The trade-off for their budget friendly price is that their standardised nature means that they offer limited flexibility in diameter, finishes, and customised details.

 Custom Made Spiral Staircases

For homeowners wanting a primary access stair, who want more of a wow factor, or want spiral staircase that is optimised for their space, a bespoke made‑to‑measure system is the right choice. A bespoke spiral staircase is not only specifically designed to your floor height and the exact diameter you require, it also allows you to choose from a much wider range of materials and styles – offering a higher level of personalisation. An entry level bespoke spiral staircase with beech treads and stainless-steel spindles will start at around £6,000. A mid-tier bespoke spiral staircase with ash or oak timber treads will generally range from £6 – 10k. For a very high specification design featuring more exotic timber types such as walnut and curved glass balustrade, prices start around £10k and for truly unique creations can range all the way up to £40,000 and more. Whilst a bespoke systems offers greater style and customisation; they are also stronger and feel more robust and can be made to meet building regulations for primary domestic staircases.

The biggest factors that can impact the final price of a spiral staircase are materials and size. Materials play a big part as some timbers like mahogany can cost 2 – 3 times that of entry level options such as beech or birch, and more premium metals like brass or copper cost considerably more than mild steel. The other major driver of cost is the height and diameter of a stair with a general rule of thumb being the bigger the stair, the higher the price. This is because more labour and material are required and additional costs like transport are more expensive

In summary, kit staircases offer a respectable budget‑friendly and practical solution, while bespoke systems provide greater flexibility, higher‑quality and more diverse finishes and greater control over style. The right choice depends on the size and location of your space, your budget, and how much of a feature you want the staircase to be in your home.
