What options are available if a standard outdoor stairlift doesn't fit my staircase?

If a standard outdoor stairlift does not fit your staircase, the most suitable alternative is usually a bespoke curved outdoor stairlift, although a platform lift, vertical lift, ramp or a different access route may be more appropriate in some properties. The correct option depends on the staircase shape, available landing space, weather exposure, surface condition and the way the user needs to travel between levels.

Bespoke curved outdoor stairlift

A curved outdoor stairlift is designed around the existing staircase rather than installed on a standard straight rail. It can be considered for stairs with bends, intermediate landings, changes in direction or unusual gradients. The rail is measured and manufactured to follow the staircase, allowing the seat to travel continuously between the required access points.

This solution may be suitable where:

• the staircase changes direction or includes a landing;
• there is insufficient room for a straight lift to stop safely;
• the stairs have an unusual width, gradient or alignment;
• the user needs to remain seated throughout the journey; or
• the stairlift must serve more than one level.

Outdoor versions need suitable protection against rain, frost, sunlight, wind and damp conditions. The assessment should consider where the chair will be parked, whether it can be kept under cover and how water will drain away from the track and charging points. A bespoke installation is generally more complex than a standard straight stairlift, so the design and site survey are particularly important.

Outdoor platform lift

A platform lift carries a person standing or seated in a wheelchair, rather than using a stairlift seat. It may be suitable where the user needs to remain in their wheelchair or where transferring onto a stairlift would be difficult. The platform travels along the staircase and normally requires enough room for the platform, safety edges, access gates and unobstructed entry and exit areas.

Platform lifts can work well on some straight or gently changing staircases, but they are not automatically suitable for every narrow or irregular flight. The folded platform, controls and landing gates must not obstruct doors, paths or escape routes. The supporting wall, stairs or adjacent structure must also be capable of accepting the installation.

Vertical platform or through-floor lift

Where the main difficulty is the staircase itself, a vertical platform lift may provide a more practical route between levels. It moves vertically between a lower and upper landing and can sometimes be installed beside the stairs, at an entrance or within a purpose-built shaft. This can avoid a winding or structurally unsuitable staircase, but it requires suitable floor and landing space, safe access at each level and, in some cases, building alterations or permissions.

A vertical lift is worth discussing when the distance between levels is relatively direct but the stairs are too narrow, steep or exposed for a conventional stairlift. The available headroom, door positions, drainage and electrical supply all need to be checked before a design can be recommended.

Ramp or reconfigured access route

A ramp may be appropriate where the change in level is modest and there is enough external space to create a safe gradient, suitable landings and edge protection. A ramp is not simply a matter of placing a sloping surface over the stairs. Its length, gradient, width, turning areas, handrails, drainage and surface grip must be considered, particularly in wet or icy weather.

If a permanent ramp would be too long or steep, other changes may be considered, such as improving an existing pathway, creating a new entrance or altering the route around the property. These options can involve construction work and should be assessed by an appropriate professional before any decision is made.

Alternative solutions for limited use

In some circumstances, the best answer is not to install a lift on the unsuitable staircase. If another accessible entrance is available, it may be possible to provide a stairlift on a different route, improve the external path or use a suitable sheltered access point. Portable ramps or temporary equipment should only be used where the gradient, surface, load and weather conditions make them safe; they are not suitable for every doorway or set of steps.

What the assessment should establish

A professional assessment should measure the complete route and consider more than whether a lift can physically fit. It should review:

• the number, shape and gradient of the steps;
• landings, bends, obstructions, gates and doorways;
• the width needed for safe travel and transfers;
• the condition and strength of walls, stairs and fixings;
• exposure to rain, wind, frost, salt, leaves and direct sunlight;
• charging, isolation and electrical requirements;
• parking space at the top and bottom of the route;
• how the user will approach, board, leave and operate the equipment; and
• safe access for other household members and visitors.

The assessment should also explain any structural work, permissions, drainage changes or ongoing maintenance that may be required. A photograph or basic measurement can indicate that a staircase is unusual, but it cannot replace an on-site survey because small changes in landing space or access direction can affect the design.

Do not choose an alternative solely because it appears cheaper or takes up less space. The safest solution is the one that provides reliable access without creating a transfer hazard, obstructing the route or exposing equipment unnecessarily to the weather. Once the site and mobility requirements have been assessed, the available options can be compared on suitability, installation work, ongoing care and total cost.
