Quick answer
The Flow X is a single-rail stairlift for straight and curved staircases, and the specification that sets it apart is width. It is published as fitting staircases as narrow as 610mm, against the 800mm that some makers state as a minimum for a curved lift. It carries up to 125kg, runs on a rail up to 35 metres at angles up to 72 degrees, and uses a system the maker calls Advanced Swivel and Levelling, which keeps the seat level as it travels through bends. UK dealers advertised it from about £4,800 to £7,195 new and from £4,150 reconditioned when we checked on 25 September 2026. No warranty length is published anywhere we could reach, which is the main gap in the public record.

Key facts
- Minimum staircase width is published as 610mm, or 24 inches, which is the lowest figure we have seen published for a curved-capable stairlift.
- Maximum user weight is 125kg, published consistently across five manufacturer sources including the user manual.
- It handles straight and curved staircases, with the maker describing straight, narrow, curved and spiral layouts. Maximum rail length is 35 metres and maximum angle 72 degrees.
- The seat stays level while the lift travels, through the maker’s Advanced Swivel and Levelling system, instead of tilting through bends.
- Warranty is not published. The one page that would settle it was not reachable, and the product documentation contains no warranty section.
- The number of rail bends it can handle is not published either, only the types of bend available.
Who makes it and who supports it in the UK
This needs stating plainly because the brand names around this product are inconsistent across the trade.
The Flow X is a TK Elevator group product. The manufacturer named on the Flow X user manual is TK Home Solutions B.V. of Krimpen aan den IJssel in the Netherlands. In the UK it is sold and branded as the Flow X by Access BDD, which describes itself as the reseller division of TK Access Solutions Ltd, based in Stockton-on-Tees and supplying stairlifts from Teesside since 1976, part of TK Elevator since 1999. Access BDD sells through a network of certified dealers, not direct.
Two clarifications worth having before you compare quotes. First, the name “Brooks Flow X” appears in places but we could not establish it: no manufacturer document mentions Brooks, Brooks Stairlifts Limited is a separate active company registered in Bradford with no group parent shown, and dealers list Brooks and Flow X as distinct ranges. We would not describe the Flow X as a Brooks product. Second, Flow2 and Flow X are different products, and TK Home Solutions’ own UK site lists neither the Flow X nor treats them as the same lift. Dealers use labels including Access BDD Flow X, TK Access Flow X and others for what appears to be one product, so check the model code on your quote.
Who it fits, and who should look elsewhere
The Flow X is aimed squarely at the staircase that other lifts do not fit: narrow, and turning. If you have been told your stairs are too narrow for a curved lift, this is the specification to put in front of a surveyor, alongside our guide on how narrow is too narrow and our page on spiral and helical staircases. The 72 degree maximum angle is also high, which matters on a steep older staircase.
The level-travel feature is relevant for anyone who finds the tilt through a bend uncomfortable or unsettling, which is a common reason people dislike a curved lift they have tried elsewhere.
Look elsewhere if the user is above 125kg, since that limit is lower than several straight-stair competitors. Look elsewhere if your staircase is straight and unremarkable, because a straight lift from any major maker will cost substantially less: the dealer prices below are curved-lift prices. And if a published warranty matters to you before signing, ask for the terms in writing, because we could not find them published.

Two notes on that table. The seat width figure appears only in the 2023 brochure, not on the product pages, and a 610mm figure that appears in the technical specification is an armrest measurement and not a seat width, so the two should not be confused. And the technical specification gives a maximum speed of 0.15 metres per second against the 0.1 metres per second nominal figure on the product pages and brochure, so we quote the nominal figure and would not present 0.15 as the rated speed. Our stairlift specifications table keeps published figures by model.
One dealer publishes a maximum user weight of 127kg, or 20 stone, against the manufacturer’s 125kg. Rely on the manufacturer’s figure.
Features as published
Advanced Swivel and Levelling is the headline feature: the seat swivels and stays level while the lift is in motion, which is what allows the narrow-staircase figure and the comfortable passage through bends.
Control is by a foldable joystick with a soft-touch grip. The seatbelt fastens one-handed, with seatbelt detection and armrest detection so the lift responds to how it is being used. Armrests wrap around and have an open-access position. Two wireless call-and-park handsets are supplied, positioned at the top and bottom of the stairs, and there is an integrated call device. Light Assist provides motion-activated lighting, armrest lighting and visual seatbelt cues. There is a diagnostic display, and the chair folds.
Rail end options are a standard drop nose needing 175mm of space, a vertical short-start drop nose needing 100mm, a horizontal overrun, and a parking curve. Rail colour options include stone grey, white, pale brown, dark brown and a grey oak wood finish, which is unusual in a market where rails are generally silver or bronze.
Battery capacity is published as ten journeys at 125kg over one floor height, and the call and park stations take AAA batteries.
Prices
The manufacturer publishes no UK price. These are dealer-advertised figures read on each dealer’s own page on 25 September 2026.
| Dealer | Condition | Advertised price |
|---|---|---|
| My Mobility UK | Reconditioned | From £4,150, listing covers Flow 2 and Flow X together |
| Senior Stairlifts | New | From £4,800 |
| Multicare Mobility | Reconditioned | £4,995 |
| Clarkshop | New | From £5,500 excluding VAT |
| Felgains | New | £5,997 excluding VAT |
| Multicare Mobility | New | £7,195 |
Read the VAT basis carefully, because two of those figures exclude it and the others do not state it. On a £5,997 lift, VAT at the standard rate is around £1,199, which is larger than the spread between several of these quotes. If VAT relief applies to the household, the comparison changes again.
Note also that these are curved-lift prices and sit in the range our stairlift prices guide gives for curved lifts generally, £4,000 to £7,000. The Flow X is not a budget alternative to a straight lift; it is a solution for a staircase that a cheaper lift will not fit. Our quote checker will place any figure you hold against current ranges, and our curved stairlift costs guide covers the type.
Warranty
This is the weakest part of the public record, and we would rather say so than fill the gap.
No warranty length is published for the Flow X in the product pages, the 2023 brochure, the technical specification or the user manual. The Access BDD service and warranty page returned an error on both attempts, so we have not read it. There is a trade report from February 2019 describing a lifetime spare-parts warranty with two-year and five-year options conditional on annual servicing, but it names other models and predates the Flow X, so we would not extend it to this lift.
What we did find is dealer-level cover, which is the dealer’s own and not the manufacturer’s: one dealer states 12 months parts and labour on a reconditioned unit, another offers an extendable warranty without stating a length, and a marketplace listing claims two years. Ask for the warranty terms in writing, ask who provides them, and ask what annual servicing is required to keep them valid.
Reconditioned market
Reconditioned Flow X units are sold in the UK, at £4,150 to £4,995 on the listings above. One dealer states it does not offer the Flow X reconditioned at all and sells new only.
Two things to check on a used Flow X in particular. One dealer’s reconditioned listing covers the Flow 2 and the Flow X together, so confirm which lift you are being quoted for. And because the rail is made to a specific staircase, ask whether the rail is original to the unit or has been re-profiled, and what that means for conformity and cover. Our reconditioned stairlifts guide covers the wider checks.
What owners discuss most
We are not able to report a review pattern for this product, and it is worth explaining why instead of presenting something thinner than it looks.
The Access BDD Trustpilot profile showed 3.7 out of 5 from 11 reviews on 25 September 2026. Eleven reviews is too small a base to describe a pattern from, and the reviews read substantially as trade and dealer feedback, and not as feedback from householders, which is consistent with Access BDD selling through dealers.
Because the Flow X reaches customers through a dealer network, the review record that matters is the individual dealer’s, not the manufacturer’s. Dealer profiles we looked at ranged from 4.9 out of 5 across 284 reviews to 3.6 out of 5 across 63 reviews, with recurring positive subjects around engineer conduct, installation and explanation, and recurring negative subjects around appointment delays, contactability and waiting times for parts or repairs. Those are the dealer’s record, not the product’s. Before you buy, look up the specific company whose name will be on your contract.
Funding
The Disabled Facilities Grant can pay towards a Flow X, up to £30,000 in England and £36,000 in Wales, means-tested for adults and not for disabled children under 18. At these prices the grant position is worth establishing before the survey, not after.
VAT relief may apply. HMRC’s VAT Notice 701/7 provides for zero-rating for customers who are chronically sick or disabled, on a written declaration, and a reduced 5 per cent rate on certain mobility aids including stair lifts for people aged 60 or over where the supplier both supplies and installs. Given that several dealers quote excluding VAT, confirm which basis applies to your figure. Our stairlift grants guide covers the route.
