Stannah Siena Stairlift Review

Stairlift Guru is independent and is not owned by or affiliated with any stairlift manufacturer.

Key facts

• Maximum user weight is 160kg on the straight version. On stairs with turns it is a range, 120 to 135kg, because the limit falls as the stair angle increases.
• Stannah publishes model numbers only in its documents, not on its product pages. Its FAQ identifies the Siena 600 as the straight model. A Siena 260 user guide also exists, with different weight limits, which UK dealers classify as the curved variant, though Stannah does not say so in the document itself.
• Stannah publishes prices, which most UK makers do not. Confirm the figure that applies to your staircase at survey, because the pricing page gives £3,585 for a new straight lift in its body copy and £3,300 in its own FAQ.
• Stannah’s general guidance is that a staircase under 700mm wide for straight stairs, or 800mm for curved, is unlikely to take a traditional stairlift.
• For narrow staircases Stannah points to its Sadler and Starla models instead of the Siena.
• New stairlifts carry a two-year warranty. Stannah’s FAQ states that offer does not apply to products bought through third-party dealers or bought with the aid of a grant, and applies to residents of England, Scotland and Wales.

Who it fits, and who should look elsewhere

The Siena suits a straight or turning staircase at least 700mm wide, or 800mm on a curve. The user needs to be within the relevant weight limit. It also suits people for whom buying direct from Stannah matters.

Buying direct is what unlocks the two-year warranty with two free services and the 14-day money-back guarantee. Stannah’s own FAQ is explicit that the warranty offer does not carry over to a lift bought through a third party or with grant funding.

Look elsewhere if your staircase is narrower than Stannah’s stated thresholds. Stannah itself points narrow-stair enquiries to other models in its range. The same goes if the user is above the weight limit for your type of staircase, which on a curved stair can be as low as 120kg.

If budget is the deciding factor, note that Stannah’s published new prices sit at the upper end of the UK market. That reflects market positioning and is no comment on quality. Our Acorn and Stannah comparison puts the two approaches side by side.

Published specification

Those width figures are the width of the stairlift, not a minimum staircase width, and the two are not interchangeable. For staircase width, Stannah’s published guidance is the 700mm and 800mm thresholds above.

Stannah doesn’t publish the seat width. It says only that the Siena comes in two seat widths.

Arm widths do appear in its brochures: 18.9 inches narrow and 21.2 inches standard. An older technical sheet gives 425mm and 496mm at the armrest. All of these are arm measurements, taken from documents of different dates, and none is a seat width.

Our stairlift specifications table puts published figures for UK models side by side.

Rails fit to the stairs, not the wall, cut to length, and Stannah states that curved rails are individually designed and take around three weeks to manufacture. Drive mechanism is not stated on any current Stannah page. Rack and pinion appears in a Stannah technical sheet issued in January 2013, which is old enough that we would not present it as the current specification.

Features as published

The Siena takes a manual or powered swivel seat, with the powered Easy-Turn offered as an option on the Siena and the Starla. The seatbelt fastens with one hand, and Stannah states the stairlift will not move unless the belt is securely fastened. Belt options across the range include lap, retractable, diagonal and a five-point harness.

The footrest folds, with manual lever or automatic button options and a powered fold button available on the Siena as an option. Safety edges on the carriage and footrest bring the lift to a stop on contact. A child lock is listed. Wall controls let the chair be called from another floor, each using three AA batteries which Stannah says last about a year in average use.

The lift runs on batteries that charge at a charge point, so you’ll need a socket at the top or bottom of the stairs. Stannah states the batteries keep working during a power cut. With a powered swivel seat, though, you have to use the manual swivel lever instead.

Its FAQ gives two different figures for how far the batteries will take you in a power cut. One answer says at least eight return journeys; another says 15 to 20 rides. Treat it as a figure to check before you rely on it.

A retractable rail that raises automatically to clear a doorway is named in the Siena 600 user guide. It does not appear on the current product pages we read, so ask about it before you assume it is available.

Prices

These are Stannah’s own published figures, read on 25 September 2026. The pricing page carries no visible last-updated date.

The same page states £3,300 for new straight stairlifts in its FAQ section against £3,585 in the body copy. We report both instead of splitting the difference, and the figure that matters is the one in your written quote.

Dealers advertise the Siena for well below Stannah’s own prices, which is the usual pattern for pre-owned units across the UK market. On 25 September 2026, Affordable Mobility, which states it is a Stannah authorised dealer, listed a pre-owned Siena 600 at £1,995. It also listed a new Siena 600 at £2,750 and a rental at £995.

GN Stairlifts listed a reconditioned Stannah 600 straight at £1,150 with taxes included. My Mobility UK sells Stannah-derived units under its own model labels, which is worth knowing when you compare listings.

Before using a dealer price as a comparison, read Stannah’s warranty condition again: its two-year new-lift offer does not apply to products bought through third-party dealers. A cheaper dealer price and Stannah’s published warranty terms are not available in the same transaction. If you are holding a quote, our quote checker will place it against current UK ranges.

Warranty and servicing

Stannah’s warranty page states that new stairlifts typically come with a two-year product warranty. That includes two free annual services, one each year, covering repairs and call-outs through the local service branch, plus 24-hour UK emergency support. Reconditioned lifts come with a one-year warranty and one free service.

Two details are worth confirming in writing. First, Stannah’s own pages disagree on the number of free services. The warranty page and pricing page say two; the Siena page and FAQ accordion say one.

Second, the FAQ puts conditions on the two-year offer. It does not apply to purchases through third-party dealers or companies, or to products bought with the help of a grant. It applies to residents of England, Scotland and Wales.

If you’re funding through a Disabled Facilities Grant, ask what warranty actually applies before you go ahead.

There is a 14-day money-back guarantee from installation on new and reconditioned lifts bought direct, which Stannah states is not available in Northern Ireland. Extended warranty can be bought at a discount before installation only.

Reconditioned market

Stannah sells reconditioned Sienas itself, which not every maker does. It states the units are never more than five years old, go through a 42-point check, come with a 12-month guarantee and one free service, and have upholstery changed to your fabric choice. For stairs with turns the rail is manufactured new, not refurbished.

Independent dealers also sell used Sienas, at £1,150 to £1,995 on the listings we read. The trade-off is the warranty position above. Our reconditioned stairlifts guide covers what to check.

What owners discuss most

The Stannah UK profile on Trustpilot showed 4.7 out of 5 from 7,053 reviews on 25 September 2026, with 84 per cent at five stars and 4 per cent at one star. The profile is claimed, on a paid subscription, and Trustpilot’s page notes Stannah replies to 98 per cent of negative reviews and asks customers for reviews.

Across the general listing, the topics that come up most are servicing and maintenance visits, engineer visits, installation and how staff come across. Punctuality, being shown how to use the lift and tidiness appear regularly. The sales process gets the least mention of these.

Filtering to one and two star reviews changes the picture. Communication with the office and getting a response comes up most. After that come servicing and annual-service arrangements, appointment timing, price and deposits, repairs and parts, and waits described in weeks or months.

That split is worth reading carefully, and not as a verdict. A large installed base generates service-visit reviews more than purchase reviews, so topic frequency reflects who writes reviews. We draw no conclusion about reliability or durability, and none is supportable from review counts.

Funding

The Disabled Facilities Grant can pay towards a Siena, up to £30,000 in England and £36,000 in Wales, means-tested for adults and not means-tested for disabled children under 18. Read Stannah’s warranty condition on grant-funded purchases before you apply, because it affects what cover you end up with.

VAT relief may also apply. HMRC’s VAT Notice 701/7 allows zero-rating for customers who are chronically sick or disabled, on a written declaration.

It also sets a reduced 5 per cent rate on certain mobility aids, including stair lifts, for people aged 60 or over. That applies where the supplier both supplies and installs. Our stairlift grants guide covers the route.
