Straight Stairlifts
Written by Dave Smith, UK-based stairlift researcher · Last updated 28 July 2026
A straight stairlift is the simplest and most affordable type of stairlift. If your staircase runs in a single straight line with no bends or landings, it's almost always the right choice — and the quickest to install.
Quick answer: A straight stairlift runs on a rail fixed to a single straight flight of stairs. It's the most affordable type, typically £2,000–£4,000 including installation, and can often be fitted in a few hours. Straight lifts are available new or reconditioned.
Which straight stairlift should you choose?
Most people asking "what's the best straight stairlift?" really mean: reliable, without paying for things they don't need. On a straight staircase the rail is a standard component, so the decision is mostly about specification and aftercare rather than engineering:
| What you want | What to ask for |
|---|---|
| Lowest sensible price, new | Standard straight model, swivel seat, seatbelt, no optional extras |
| Lowest price overall | A reconditioned straight model, if one fits your stairs |
| Extra comfort for stiff hips or knees | Powered swivel seat and powered footrest |
| Heavier user | Heavy-duty model — Acorn's 130 offers a 159kg heavy-duty version against 127kg standard |
| Fitted in days, not weeks | Straight model with simple specification — see urgent installation |
| Short-term need only | Rental instead of buying |
The lift we can arrange a quote for is the Acorn 130 Straight: a focused single straight model, a 12-month manufacturer's guarantee, and next-day installation availability. If you want a wider choice of upholstery and styling, compare stairlift brands and read Acorn vs Stannah before you commit.
Whatever the badge, judge two written numbers: the total fitted price and the cost of servicing once the warranty ends — see warranty and aftercare.
What is a straight stairlift?
A straight stairlift carries a comfortable seat up and down a rail that's fixed along one straight flight of stairs. Because the rail is simply cut to the right length — rather than custom-shaped to your staircase — it's the most affordable kind to supply and the fastest to fit.
The seat glides smoothly from bottom to top at the touch of a control, with a soft start and stop. At the top, a powered swivel seat turns so you can step off safely onto the landing.
Who a straight stairlift is best for
A straight stairlift is the right choice if:
- Your staircase goes straight up with no bends, turns or half-landings.
- You want the most affordable option.
- A quick installation matters to you.
- You're open to a reconditioned model to save even more.
If your stairs have a bend or a landing, you'll need a curved stairlift instead, as the rail has to follow the shape of the staircase.
How much does a straight stairlift cost?
Straight stairlifts typically cost between £2,000 and £4,000, including installation. A reconditioned straight model can cost less again. Eligible customers pay no VAT, a further 20% saving. For a full breakdown, see our guide to stairlift costs and VAT exemption.
Features to look for
Even on a straightforward straight staircase, a few features make a real difference to comfort and safety:
- Powered swivel seat — turns the seat at the top so you can get on and off safely.
- Seatbelt — for security throughout the ride.
- Safety sensors — stop the lift automatically if something is in its path.
- Simple controls — an easy paddle or toggle is far easier to use than fiddly buttons.
- Fold-away design — the seat, arms and footrest fold up so others can still use the stairs.
How is a straight stairlift installed?
The rail fixes to the stair treads themselves — not the wall — so it suits almost any home and won't damage your walls or décor. Installation is usually quick, often completed in a few hours on a single visit. When you request a quote, Acorn assesses your staircase, then supplies and fits the stairlift.
Straight or curved — how to tell which you need
| Your staircase | What you need |
|---|---|
| One straight flight, top to bottom | Straight stairlift, £2,000–£4,000 fitted |
| A bend, winder or half-landing | Curved stairlift, from around £5,000 |
| Two straight flights split by a full landing | Sometimes two straight lifts — a survey question |
| Straight but unusually narrow | Straight lift with a slim, fold-away seat — see narrow stairs |
| Straight but very steep | See steep stairs |
If you're unsure, don't guess from a photo. The surveyor measures it and tells you for free.
Folding rail, narrow stairs and powered options
Three details decide whether a straight lift feels right day to day:
- Fold-away seat, arms and footrest. Everything folds flat against the rail so the stairs stay usable for everyone else in the house.
- Hinged (folding) rail. If the bottom of the rail would sit across a doorway, hallway or another flight, a hinged section folds up out of the way. Ask about it at the survey if the bottom step opens onto a door.
- Narrow staircases. A straight lift is usually the answer on tight stairs, because the rail is slim and the seat folds. What matters is the usable width once the rail is fitted — see stairlifts for narrow stairs.
- Powered swivel seat and powered footrest. Worth the extra if bending or twisting is painful; the seat turns you towards the landing at the touch of the control.
The installation, step by step
- Free survey — the staircase is measured and the model confirmed.
- Rail cut to length — no manufacturing wait on a standard straight rail.
- Fitting — the rail is fixed to the stair treads, not the wall, usually in a few hours on one visit.
- Testing and handover — the fitter runs the lift and shows you how to use it before leaving.
- Aftercare — annual servicing keeps it running; see warranty and aftercare.
New or reconditioned?
Straight staircases are the one place a reconditioned stairlift really shines, because the standard rail suits pre-owned models. A reconditioned lift costs less but comes with a shorter warranty and less choice. Our new vs reconditioned guide helps you weigh it up.
Because a straight stairlift depends entirely on your staircase measurements, the only way to get an exact price is a quick assessment. It's free and no-obligation — just fill in the form below and Acorn Stairlifts will provide your quote.
