UK Stairlift Glossary: Stairlift Terms Explained

Last updated: 22 June 2026 · An independent, plain-English glossary of UK stairlift terms. Free to cite with attribution.

Buying a stairlift means wading through industry jargon, rail types, grant acronyms and technical specifications. This glossary explains the terms you will meet, in plain English, with links to our fuller guides where useful. Stairlift Guru is independent and does not sell stairlifts.

A to D

Batteries (DC powered)

Almost all UK stairlifts run on rechargeable batteries rather than mains power directly. The lift charges at parking points on the rail, so it keeps working during a power cut. Batteries typically last three to five years before they need replacing.

Call and send controls

Wireless remote handsets (usually two) that let you call the stairlift to the top or bottom of the stairs when someone else has left it at the other end.

Carriage

The moving body of the stairlift that travels along the rail and carries the seat, footrest and controls.

Curved stairlift

A stairlift with a rail custom-made to follow stairs that turn, bend, have half-landings or intermediate landings. Because the rail is bespoke, curved models cost more than straight ones. See our curved stairlifts guide.

E to H

Footrest safety sensors

Pressure-sensitive edges on the footrest (and often the carriage) that stop the lift automatically if they meet an obstruction on the stairs.

Hinged rail (folding rail)

A section of rail at the bottom of the stairs that folds up manually or automatically, so the rail does not overhang a doorway, hallway or fire exit at the foot of the stairs.

Heavy-duty stairlift

A model built for higher user weights, typically up to 25–32 stone (160–200 kg), with a wider seat and reinforced carriage. See our heavy-duty stairlifts guide.

I to P

Occupational therapist (OT)

A health professional who assesses a person’s mobility and home to recommend suitable adaptations. An OT assessment is usually the first step in a Disabled Facilities Grant application.

Disabled Facilities Grant (DFG)

A means-tested council grant in England, Wales and Northern Ireland that can pay for home adaptations including stairlifts. The maximum award is £30,000 in England, £36,000 in Wales and £25,000 in Northern Ireland. See our stairlift grants guide.

Outdoor stairlift

A weatherproofed stairlift for external steps, such as a path or garden stairs, with sealed components and a waterproof cover. See our outdoor stairlifts guide.

Perch seat

A small, semi-standing seat for users who find it hard to bend their knees or sit fully. Useful on narrow staircases where a standard seat will not fit.

R to S

Rail (track)

The metal track fixed to the stair treads (not the wall) along which the carriage travels. Straight rails are cut to length; curved rails are manufactured to the exact shape of the staircase.

Reconditioned stairlift

A second-hand stairlift that has been refurbished, safety-checked and resold, usually with a warranty. Typically 30–50% cheaper than new. See our reconditioned stairlifts guide.

Rental stairlift

A stairlift hired on a monthly basis rather than bought outright, common for short-term needs. UK rentals typically cost about £65 a month plus an installation fee. See our stairlift rental guide.

Safety belt (retractable)

A lap or harness belt fitted as standard to keep the user secure during travel.

Seat swivel

A mechanism that turns the seat (commonly 45°, 90° or up to 180°) at the top of the stairs so the user can get on and off facing away from the steps. May be manual or powered.

Soft start and soft stop

A feature that makes the lift begin moving and come to a halt gradually rather than abruptly, for a smoother, more comfortable ride.

Standing (stand-on) stairlift

A stairlift used in a standing or perching position, suited to very narrow stairs or users who cannot bend their knees comfortably.

Straight stairlift

A stairlift for a staircase with no bends or landings. The rail is a single straight length, which makes it the cheapest and quickest type to install. See our straight stairlifts guide.

T to Z

Track overrun (nose)

The short extension of rail beyond the top or bottom step that lets the carriage travel far enough for safe, level boarding. A hinged rail is one way to manage overrun at the bottom.

VAT exemption (zero-rating)

Relief from VAT on a stairlift for people who are chronically sick or disabled, or for someone buying on their behalf. Eligible buyers pay roughly 17% less than the standard price. Estimate your saving with our VAT exemption calculator.

Weight capacity (safe working load)

The maximum user weight a stairlift is rated to carry. Standard models usually carry up to about 18–20 stone (115–127 kg); heavy-duty models carry more.

FAQ

What is the difference between a straight and a curved stairlift?

A straight stairlift fits a staircase with no bends or landings and uses a single straight rail, so it is cheaper and quicker to install. A curved stairlift has a rail custom-made to follow stairs that turn or have a landing, which costs more.

What is a perch stairlift?

A perch stairlift has a small semi-standing seat for users who cannot bend their knees easily or who have very narrow stairs where a standard seat will not fit.

What is a hinged rail on a stairlift?

A hinged rail is a folding section at the bottom of the stairs that lifts out of the way so the rail does not block a doorway, hallway or fire exit.
