Straight vs Curved Stairlifts

Short answer: if your staircase is a single continuous flight with no turns and no landings, you need a straight stairlift — fitted within 24–48 hours from £1,995. If your stairs turn at any point, include a half-landing, or have a 180° switchback, you need a curved stairlift — made to measure in 1–3 weeks from £2,995 (or 48 hours with our Emergency option).

The difference matters because the rail is the most expensive part of any stairlift, and the two types are engineered very differently.

How to tell which you have

Stand at the bottom of your stairs and look up.

• Single straight flight, top of stairs visible from the bottom? → straight stairlift
• Stairs turn at the top, the bottom, or both? → curved stairlift
• Half-landing partway up where you change direction? → curved stairlift
• 180° switchback (two flights with a landing between)? → curved stairlift
• Spiral staircase? → usually a curved stairlift; some don't fit any lift — survey confirms

Side-by-side comparison

Both are battery-powered, both keep working in a power cut, both fold away when not in use, and both meet BS EN 81-40.

Why curved costs more

A straight rail is stock. We carry common rail lengths in the van, cut to length on the day, and bolt to the treads. That's why a straight lift can be fitted within 48 hours of survey for £1,995.

A curved rail is unique to your staircase. The surveyor uses a digital measuring system to capture every angle, turn and landing, and a 3D model is sent to the factory. The rail is then manufactured to fit your exact stairs — every join, every bend, every clearance. That's 1–3 weeks of manufacturing time, plus a more complex 3–4 hour fitting. The price reflects that.

When the line blurs

• Single straight flight with a flat top landing where the seat needs to clear a door — straight lift, with a hinged rail at the bottom (£150–£300 option).
• Straight flight that stops 1–2 steps short of the landing — straight lift with an extended rail; usually no extra charge.
• Quarter-turn at the very bottom (winder) but otherwise straight — usually a curved lift, because the rail has to follow the bend. Occasionally a straight lift with a short transfer step.

The free home survey gives a definitive answer — we don't quote curved unless your stairs genuinely need it.

Reconditioned: only straight

We fit reconditioned straight lifts for £995 because the rail is stock and the chair has been workshop-refurbished. Reconditioned curved is rarely viable — the rail from one staircase almost never fits another. If you have curved stairs and a tight budget, our £2,995 fixed price for a new curved lift is usually the best route, with VAT relief if eligible.

Lead time: when curved Emergency makes sense

Standard curved manufacturing is 1–3 weeks. For urgent cases — hospital discharge, end-of-life care, rapid mobility decline — our Emergency option compresses that to 48 hours. There's an additional manufacturing surcharge; we quote the all-in price on the day of the survey.

If the user can manage stairs for a couple of weeks while a standard curved lift is made, standard timing is more cost-effective. If they genuinely can't, Emergency is the right call.

Which one we'd recommend, in plain terms

• Single straight flight, permanent need → new straight at £1,995 fitted
• Single straight flight, tight budget or short-term need → reconditioned at £995 fitted
• Any turns, half-landings or switchbacks → curved at £2,995 fitted
• Curved stairs, urgent fit needed → curved with the Emergency option
