How to Choose a Stairlift — A Guide for UK Homeowners

Choosing a stairlift does not have to be complicated. There are really only a handful of decisions to make, and most of them come down to your staircase and the person who will be using the lift. This guide walks through each step in plain English so you can approach the process with confidence.

Work Out What Type You Need

The first decision is always the type of stairlift, and it is driven entirely by the shape of your staircase.

If your staircase runs straight from bottom to top with no bends or landings, you need a straight stairlift — the most common and most affordable type. If your stairs change direction at any point — a bend, a quarter turn, a half landing — you need a curved stairlift, which is custom-made for your staircase. If your steps are outside the house, an outdoor stairlift is the right solution.

For a more detailed explanation of the differences, see our straight vs curved stairlift guide.

Think About the User’s Needs

The best stairlift is one that the person using it finds genuinely comfortable and easy to operate. A few things are worth thinking through before you speak to any supplier.

Weight capacity Most standard stairlifts support up to around 120kg. If the user is above this, ask specifically about heavy-duty models — they are widely available but not always the default option a supplier will quote for.
Seat height and comfort This matters particularly for anyone with hip or knee problems. Getting in and out of the seat should feel natural and require minimal effort. Mention any joint conditions to the surveyor so they can recommend the most suitable seat height and configuration.
Controls Most stairlifts are operated via a joystick on the armrest. Remote control handsets should also be included so other family members can call or send the lift from either end of the stairs. Make sure both are included in the quote as standard.
Swivel seat A powered swivel seat rotates the chair away from the stairs before the user stands up, which makes getting on and off considerably easier — especially at the top of the stairs where a straight dismount would be awkward. Worth considering for anyone with limited mobility.
Powered footrest A powered footrest folds up and down automatically rather than requiring the user to do it manually. A useful upgrade for anyone who finds bending difficult.

Consider the Practical Details

A few practical points are worth checking before you commit to a particular model or supplier.

Rail width A stairlift does not block the staircase for other users. The rail sits close to the wall and the seat folds away when not in use, leaving most of the stair width clear. A surveyor can confirm whether your staircase is wide enough — most UK stairs are perfectly suitable.
Folding rail option If the stairlift rail extends to the very bottom step, it may partially obstruct a hallway door. Many suppliers offer a hinged rail section at the bottom that folds out of the way when the lift is not in use. Ask whether this applies to your layout.
Power supply Stairlifts run on a rechargeable battery that charges from a standard mains socket when the lift is parked. This means they continue to work during power cuts — a significant practical advantage for many users.
Warranty Look for at least 12 months parts and labour warranty as a minimum. Some manufacturers offer two years or more. Check whether the warranty is provided directly by the supplier or by the manufacturer, and what the process is for calling out an engineer if something goes wrong.

Find a Reputable Supplier

Choosing the right supplier matters just as much as choosing the right stairlift. Here is what to look out for.

Get at least two quotes before making a decision. Prices can vary, and comparing suppliers also gives you a sense of how they communicate and whether they feel trustworthy.
Ask exactly what the warranty covers — parts only, or parts and labour? Is there a call-out charge? How quickly do they respond to faults?
Check the company is established and look for verifiable independent reviews. A company with a track record is far preferable to one that appeared recently.
Be wary of high-pressure sales tactics. A reputable supplier will give you a written quote and allow you plenty of time to compare and decide. If you feel pushed to sign on the day, that is a warning sign.
A free, no-obligation home survey is completely standard in the stairlift industry. Never pay for a quote.

Understand the Cost

Stairlift prices vary depending on type, staircase, and the features you choose. As a general guide:

Straight stairlift (indoor)

£1,200 – £2,800

Curved stairlift (indoor)

£3,000 – £7,000

Straight stairlift (outdoor)

£2,500 – £4,500

These are indicative prices and vary by supplier and specification. For a full breakdown of what affects cost, see our stairlift cost guide.

Get a Free Home Survey

The home survey is the single most important step in the whole process. Everything before this — reading guides, comparing prices online — is useful preparation, but the survey is where you get a firm recommendation and an accurate written quote.

A specialist visits you at home, measures the staircase, discusses the user’s needs, and recommends the right type and model. You receive a written quote with no obligation to proceed. The whole visit typically takes around an hour.

There is no charge for the survey. If any company suggests there is, look elsewhere.

We recommend booking surveys with at least two suppliers so you can compare both the quote and the experience of dealing with them. Take your time, ask questions, and do not feel pressured to make a decision on the day.
