What factors should I consider when comparing the costs of straight and curved Stannah stairlifts?

Straight Stannah stairlifts are generally less expensive than curved models because a straight lift uses a standard rail, whereas a curved lift requires a bespoke rail made to follow the exact shape of the staircase. However, the most useful comparison is not the headline price alone. Consider the rail design, installation requirements, seat and control options, warranty, aftercare and any work needed to prepare your home.

Compare like-for-like quotations

Before comparing prices, check that both quotations describe a suitable solution for the same staircase and include the same level of service. A lower price may not represent better value if it excludes installation, delivery, removal of an existing lift, servicing or follow-up support.

Ask each quotation to identify:

• The stairlift model and whether it is new or reconditioned
• The type and length of rail included
• Installation, testing and user instruction
• Any electrical or minor preparation work
• Warranty cover and the availability of aftercare
• Any optional features selected
• Whether removal of an old stairlift is included

A home assessment should confirm the appropriate lift and provide a more reliable price than a general online estimate. The condition, width and layout of the staircase can affect what is practical, particularly where access is restricted or the stairs have unusual dimensions.

Why straight stairlifts usually cost less

A straight stairlift travels along one uninterrupted flight of stairs without changing direction. Its rail is usually manufactured in a standard configuration, which makes production and installation more straightforward. The installation process may also be quicker when the staircase is accessible and does not require alterations.

The cost can still vary according to the model, seat type, weight capacity, controls, finish and safety features. A straight staircase with a landing, narrow entrance or limited space at the top or bottom may also require a particular seat or rail arrangement. If the stairs are not completely straight, a curved solution may be needed even if the change in direction appears small.

Why curved stairlifts usually cost more

A curved stairlift is designed for staircases that turn, include intermediate landings, have multiple flights or follow a more complex route. The rail is measured and made specifically for the property. This bespoke design is the main reason curved stairlifts generally have a higher cost than straight models.

Curved installation can involve more detailed surveying, manufacturing and fitting. The installer may need to consider several factors, including the position of landings, the available space around bends, obstruction from doors or furniture, and where the user needs to get on and off the lift. A rail that follows the stairs closely can also be designed to park in a position that helps preserve access to the landing or hallway.

Not every curved staircase requires the same amount of work. A simple turn may be less involved than a staircase with several bends or floors, so a curved stairlift should be priced after an assessment rather than judged from a general cost range.

Consider the installation environment

The staircase itself is only part of the assessment. The installer will also consider the structure of the stairs, the position of handrails, doorways, radiators, furniture and nearby power points. A suitable power supply is normally required, and the installation team should explain any preparation needed before fitting.

For a straight lift, these factors may have a relatively limited effect on the price, but they can affect the choice of rail and seat. For a curved lift, they can influence the rail design and parking position. If access is needed at both the top and bottom, or if the lift must park away from a doorway, this should be discussed during the survey.

Separate essential requirements from optional features

Features should be compared according to how they support safe and practical use, rather than simply adding every available option. Depending on the model and the user’s needs, features may include powered swivelling, powered folding, a powered footrest, different seat widths, adjustable armrests, remote controls and alternative upholstery or finishes.

Some options can make transfers easier or improve comfort, but they may increase the purchase price and can affect the overall specification. A powered feature may also introduce additional components that should be covered by the warranty and maintained as part of the aftercare service. Ask for each optional item to be listed separately so you can see its effect on the quotation.

Include warranty and aftercare in the comparison

The initial purchase price does not represent the whole cost of ownership. Check the length and scope of the warranty, including whether it covers parts, labour and call-outs. Confirm what happens if the lift requires attention after installation and whether servicing arrangements are available.

A curved stairlift has a bespoke rail, so ask how any future changes, repairs or relocation would be handled. If you may move home, it is also worth asking whether the lift can be removed, adapted or reinstalled elsewhere. The answer will depend on the rail design and the new staircase, so it should not be assumed that a curved lift can be transferred without further assessment.

For a reconditioned stairlift, establish what inspection, refurbishment and testing have been carried out, what warranty is provided and whether the rail is new, reused or made for the particular staircase. A reconditioned option may have a different price structure from a new installation, but it still needs to be suitable for the user and the property.

Check payment and finance arrangements

If you are considering finance, compare the total amount payable rather than only the regular payment. Check the deposit, repayment period, interest or other charges, and the consequences of changing or ending the agreement. Finance availability and terms can vary, so ensure the arrangement is clear before proceeding.

It can also help to ask whether the quotation is for a complete installation or only for the equipment. This avoids comparing a cash purchase with a finance plan or a package that includes different levels of warranty and service.

Use the home assessment to make the final decision

The right choice is determined by the staircase and the user’s mobility, not by cost alone. A straight lift is normally the more economical option where the stairs are a single, uninterrupted flight and the standard rail meets the access requirements. A curved lift is usually necessary where the staircase changes direction or has several flights, and its higher cost reflects the bespoke rail and more involved design.

During the assessment, discuss where the user will transfer on and off the lift, whether they need to carry walking aids, how much landing space must remain clear and which controls they can operate comfortably. Then request a written quotation that separates the lift, rail, installation, options, warranty and aftercare. This gives you a fair basis for comparing straight and curved Stannah stairlift costs and helps prevent unexpected charges later.
