Bariatric Stairlift Cost: What You Need to Know
If you’re exploring mobility solutions for yourself or a loved one, you may be wondering about the cost of a bariatric stairlift. These specialised stairlifts are designed to support higher weight capacities, providing safe and comfortable transport up and down stairs for individuals with larger body frames. But how much should you expect to pay, and what factors influence the final price?
In this article, we’ll break down the typical costs of bariatric stairlifts in the UK, what features are worth considering, and how to get the best value for your investment.
What Is a Bariatric Stair Lift?
A bariatric stairlift—also known as a heavy-duty stairlift—is engineered to safely carry users weighing more than standard stairlifts can accommodate. While regular stairlifts typically support up to 120–160kg (18–25 stone), bariatric models can handle heavier weights of up to 25-30 stone depending on the make and model.
These stairlifts are ideal for users who require a stronger seat, reinforced rail, and extra safety features to ensure smooth, stable operation on both straight and curved staircases.
How Much Does a Bariatric Stairlift Cost?
The cost of a bariatric stairlift in the UK usually starts at around £2,800 for a straight stairlift and around £6,250 or more for curved stairs or more customised installations.
Key factors that influence bariatric stairlift pricing include:
-
Staircase type – Straight staircases are more affordable; curved or spiral stairs require bespoke rails.
-
Weight capacity – Higher weight limits often come with more robust construction and added cost.
-
Seat and rail upgrades – Wider seats, powered swivel options, and heavy-duty rails may increase the total price.
-
Installation complexity – Stair width, obstructions, or additional electrical work can affect fitting costs.
-
Brand and features – Top-tier models from trusted manufacturers may command higher prices due to durability and comfort.

Makes And Models
If you’re in need of a bariatric stairlift, we can help. Depending on your staircase layout and your measurements and weight, we would either recommend a Bruno heavy duty stairlift or a Platinum Ultimate (heavy duty) stairlift.
The Bruno stairlift has a larger weight capacity than the Platinum (30 stone). However, the Bruno faces outwards on the staircase, which can present problems depending on the minimum width of your staircase.
Your back to knee/toe measurement is critical when it comes to a heavy weight stairlift, especially with the Bruno. The Platinum stairlift allows you to travel facing downstairs, so has greater dexterity when it comes to a narrower staircase. However, there must be room to swivel the chair at the top/bottom for entry and exit and the Platinum has a lower weight capacity (25 stone).

Other Considerations – Leg Dexterity
If you struggle to move your feet underneath your knees, this can present a problem. This might mean your back to toe measurement is the critical one, as opposed to the back to knee measurement. This figure will determine which make and model is most suitable, if any, when compared to the minimum width of the staircase.
To measure for a Bruno stairlift, you should take your back to toe/knee measurement and add 100mm-150mm. Then compare this figure to the narrowest part of your staircase. There should be room for manoeuvre. If not, the Platinum stairlift might be the only option if you’re over the weight limit for a standard stairlift.
With the Platinum, there needs to be room for the swivel, to rotate you at the top/bottom for entry and exit. So while the Platinum allows you to face downstairs, this manoeuvre still needs to be considered.
