What specific staircase features should I consider when evaluating my Stannah stairlift options?

The most important staircase features to assess when comparing Stannah stairlift options are the stairway’s layout, width, gradient, headroom and the space available at the top and bottom. Bends, intermediate landings, changes in direction and obstructions such as doors or radiators determine whether a straight or curved rail is suitable, how the lift can be positioned and what installation work may be required.

A professional survey should examine the complete route rather than just the visible flight of stairs. The aim is to confirm that the chosen Stannah stairlift can travel safely, leave enough room for people to use the stairs and park in a practical position without blocking a doorway or important access route.

Staircase shape and direction

First, identify whether the staircase is a single, uninterrupted flight or follows a more complex route. A straight staircase generally has a simpler rail arrangement, while a staircase with a bend, curve, half landing or change of direction usually requires a curved stairlift designed around its individual measurements.

• Single flight: A straight rail may be appropriate where the stairs run continuously between the lower and upper floors.
• Quarter-turn or half-turn layout: A landing or change of direction may require a curved rail, or occasionally more than one lift, depending on the available space and the preferred route.
• Several bends: Multiple curves affect the rail design, travel path and parking position. The survey should establish whether the lift can follow the inside or outside of the staircase safely.
• Split-level or unusual layouts: Changes in floor level, winder steps and non-standard landings need careful measurement because they can affect both the rail profile and where the user gets on or off.

A landing is not automatically a problem, but its size and shape matter. The stairlift may need to turn, stop or park without reducing access to adjoining rooms. If the staircase has an intermediate landing, ask where the lift will be positioned when it is not in use and whether the proposed route avoids creating a trip or collision hazard.

Stair width and available clearance

The width of the staircase affects the choice of seat, armrest configuration, rail position and the amount of room left for other people to pass. A narrow staircase may still accommodate a Stannah stairlift, but the surveyor may need to consider a compact seat, a folding mechanism or a different rail position.

Measure more than the distance between the walls. Bannisters, dado rails, skirting boards and projections can reduce the usable width. Also consider the width of the user, the position of their feet and whether the stairlift can be folded away when someone else needs to use the stairs. Where the staircase is shared or forms a main household route, this clearance is particularly important.

Headroom, ceiling height and stair gradient

Headroom should be checked at the points where the user may be closest to the ceiling, particularly near landings, turns and the top of the staircase. Low ceilings, beams and sloping ceilings can influence the seat position, the direction of travel and the safest parking point.

The gradient may also change along the route. A consistent flight is easier to assess, whereas steep, shallow or changing gradients may require a more carefully configured rail and seat arrangement. The survey should consider the user’s posture, leg position and ability to get on and off comfortably, not just whether the lift can physically travel up the stairs.

Top and bottom parking areas

There needs to be a suitable place to park the stairlift at the lower and upper ends, or at another agreed point on a curved route. Check whether the parked lift would obstruct:

• a front or internal door;
• a hallway, corridor or landing;
• the opening of a cupboard or nearby room;
• the bottom step or a walking route; or
• access to another level of the property.

Some layouts benefit from a parking position that moves the chair away from the top step or around a bend. This can require additional rail length and may influence the final price. The best position should be agreed during the assessment rather than assumed from a photograph or a basic measurement.

Doors, radiators and other obstructions

Doors close to the staircase can restrict where the chair parks or where the user can transfer safely. Radiators, light switches, heating controls, shelves and wall-mounted items may also interfere with the rail, seat or user’s knees. A survey should record whether these items need to be moved, protected or worked around.

Bannisters and handrails deserve particular attention. They may affect the rail position or leave insufficient room for a person to grip the rail while walking. Removing or adapting a bannister is not always necessary, but the implications should be explained before installation. Furniture and household equipment near the stairs should also be considered, especially if the stairlift is intended for daily use.

Access to the seat and transfer space

The user must be able to approach the stairlift, sit down securely and place their feet correctly. Look at the space beside the first step, the width of any landing and whether the user approaches from the left or right. If transferring from a wheelchair, walking frame or another mobility aid, there should be enough room to position that aid without blocking the staircase.

At the upper floor, the user should be able to leave the seat without stepping into a doorway, against a wall or directly onto an obstructed landing. A powered swivel seat or a different parking arrangement may help in some layouts, but the appropriate solution depends on the user’s mobility and the available clearance.

Stair and wall condition

The installer should check that the steps, walls and fixing points are suitable for the proposed rail. Loose treads, damaged flooring, weak surfaces or unusual construction may need attention before installation. The rail is normally secured to the stairs rather than relying solely on the wall, but the exact fixing method depends on the staircase and its condition.

Floor coverings can affect the installation if they are loose, excessively thick or uneven. Tell the surveyor about planned decorating, flooring changes or building work so that the rail position and installation sequence can be considered properly.

Power supply and charging position

Stannah stairlifts require a suitable electrical supply and charging point. The location of the power socket and the proposed parking position should allow the lift to charge reliably without creating a trailing-cable hazard. If the existing socket is inconvenient, the installer can advise whether an electrical alteration is needed and whether that work is included in the quotation.

Outdoor or exposed staircases

For external stairs, assess exposure to rain, wind, damp, dirt and temperature changes, along with the condition of the steps and nearby walls. The lift and charging arrangement must be appropriate for the environment, and the parking area should offer suitable protection where possible. Drainage, a covered entrance and the condition of the electrical supply may all affect the installation requirements and cost.

When reviewing a quotation, ask the surveyor to explain how each staircase feature has influenced the recommended Stannah model, rail design, seat configuration, parking position and installation work. A useful assessment should also identify any access limitations, required alterations and possible alternatives. This gives you a clearer comparison between options and helps ensure that the selected stairlift is practical for both the staircase and the person who will use it.
