Stairlift or Move Downstairs? Comparing the Two Options

Key facts

• A disabled wet room or accessible shower room costs £5,000 to £15,000 in the UK, with an average around £10,000, according to Checkatrade’s cost guide updated in June 2026.
• Where there is no suitable ground-floor room and an extension is needed, the figure changes completely. Single-storey extensions run £1,800 to £3,000 per square metre, so a modest 20 square metre addition is £40,000 to £56,000.
• A straight stairlift is £1,500 to £3,500 installed and goes in within a few hours. Removing it later costs £80 to £300 and leaves screw holes in the treads, not structural damage.
• In many UK homes the only bathroom is upstairs. That single fact decides this question more often than cost does.
• The Disabled Facilities Grant can fund either route, up to £30,000 in England and £36,000 in Wales, means-tested for adults but not for children under 18.
• Moving downstairs takes a reception room out of use permanently. Think about where visitors sit and where the person spends the day. Where they sleep is only part of it.

Who this suits, and who it does not

Moving downstairs suits someone who already has a ground-floor room that can be given up, with a bathroom or a space for one within reach of existing drainage. It suits people who will probably need a wheelchair, because a stairlift carries a person and not a chair. It suits anyone for whom an occupational therapist has judged a stairlift unsafe, and anyone who finds the stairs frightening and not merely difficult, since a lift does not remove the fear of the staircase itself.

A stairlift suits the larger group: people who can still walk and transfer, who want to keep using their bedroom and bathroom, and who do not want to lose a room. It suits anyone whose need may be temporary, after an operation for instance, and anyone who wants to spend less and decide later.

Neither suits a household where the ground floor has no space to spare and no scope for an extension. There, the honest options are a through-floor lift, which starts at around £17,000 before VAT, or moving house. We cover both in stairlift vs home lift explained and stairlift vs moving house.

What moving downstairs actually involves

People picture a bed in the front room. The bed is the easy part. Four other things decide whether this works.

The bathroom is the first and biggest. A ground-floor WC is common in UK homes; a ground-floor bath or shower is not. If the only bathroom is upstairs, moving downstairs means building a shower room, and that means drainage. Where a new shower room sits near the existing soil stack, costs stay at the lower end. Where it does not, a pumped waste system or a new run adds cost and complexity. This is the item that turns a £6,000 project into a £15,000 one.

Space is the second. Taking a reception room for a bedroom removes it from daily life. In a three-bedroom terrace with two downstairs rooms, that is often manageable. In a house with one through-lounge, it means sleeping in the room where the television is and where visitors sit. Families underestimate how much that changes the feel of a home, and it is the most common regret we hear about.

Building control is the third, and it is worth a conversation, not an assumption. Converting a room to a bedroom can raise questions about means of escape, particularly where the new bedroom becomes what building regulations call an inner room, reached only by passing through another room. Escape windows for habitable rooms are generally specified at no higher than 1.1 metres from floor level and at least 450mm by 450mm with a third of a square metre of clear opening. Whether any of that applies to your conversion depends on the layout, so ask your council’s building control team before work starts, not after.

The upstairs is the fourth, and it is the one nobody plans for. A floor that stops being used still needs heating enough to avoid damp, and still needs someone to check it. Cold, unventilated bedrooms develop condensation and mould. If nobody goes up for months, a leak is found late. Households that move downstairs successfully usually keep the heating on low upstairs and have someone look round every few weeks.

Cost comparison

Stairlift figures are the ranges published on our stairlift prices guide, reviewed September 2026. Wet room and extension figures are from Checkatrade’s cost guides updated June 2026. The through-floor figure is Stiltz’s own published starting price, excluding VAT, checked 25 September 2026.

The cost nobody quotes

A stairlift has ongoing costs and a conversion mostly does not. Budget £80 to £180 a year for a stairlift service and £60 to £120 for batteries every three to five years. Over ten years that is perhaps £1,200 to £2,400 on top of the purchase.

A conversion has no service contract, but it changes your bills. Heating a ground-floor room used day and night, while keeping an unused upstairs above freezing, is not obviously cheaper than before. And an accessible shower room used daily will need work sooner than a spare bathroom would.

Neither of these changes the ranking. They narrow the gap.

What the grant will cover

The Disabled Facilities Grant covers both routes. GOV.UK describes it as help with the costs of making changes to your home so you can continue to live there, which is broad enough to include a stairlift, a downstairs shower room, or a ground-floor extension where an assessment supports it. The maximum is £30,000 in England and £36,000 in Wales. For adults it is means-tested on household income and on savings above £6,000. For children it is not: GOV.UK states that disabled children under 18 can get a grant without their parents’ income being taken into account.

In Northern Ireland the grant is administered by the Northern Ireland Housing Executive, with a maximum of £35,000 and discretion to increase an award up to £70,000 in some cases. Scotland works differently again, through council assessment and no fixed grant cap.

Two points matter for this decision in particular.

Councils fund what the occupational therapist assesses as necessary and appropriate. If an OT concludes a stairlift meets the need, a council is unlikely to fund a £15,000 conversion instead. If the OT concludes the person cannot use a stairlift safely, the conversion becomes the recommended option and the funding position changes with it. The assessment, not the quote, drives the outcome, so get it first. Our guide on what an occupational therapist does explains how to ask.

VAT treatment differs between the two. A stairlift supplied and installed for someone who is chronically sick or disabled can be zero-rated under HMRC’s VAT Notice 701/7, on a written customer declaration. For building work the position is narrower and more specific: the notice allows zero-rating for certain services such as constructing a ramp or widening an existing doorway or passage to help a disabled person get into or move about the building, which is not the same as zero-rating a whole shower room or extension. Ask your builder to confirm in writing which elements of a conversion they are treating as zero-rated and why, and expect standard VAT on much of the work.

What people regret

The permanence is the main risk. A stairlift comes out in an afternoon. A conversion does not, and if circumstances change, for instance if the person recovers mobility after a hip replacement or moves into care within a year, you are left with a bedroom where your sitting room was and a bathroom you did not need. Conversions are best where the need is settled and progressive, not where it is new and uncertain.

Resale is a smaller risk than people fear but not nothing. A well-built downstairs shower room usually adds value or is at worst neutral. A former reception room still configured as a bedroom, with no sitting room left, narrows the pool of buyers. If resale matters, design the conversion so the room still reads as a room, not as a permanent bedroom.

There is a quieter cost too. Moving downstairs concentrates someone’s whole life into one or two rooms, and it removes the daily movement that using the stairs provided. Some people find that a relief. Others become less active and more isolated, and the stairs turn out to have been doing something useful. A stairlift keeps the upstairs in reach and keeps the household shape intact, which is why many occupational therapists suggest trying it first where it is safe to do so.

Finally, do not treat this as a decision between two options only. Our guide to the alternatives worth considering first covers grab rails, a second banister, better lighting and a downstairs WC, any of which may defer the whole question by years at a fraction of the cost.

Frequently asked questions

Is it cheaper to move downstairs or fit a stairlift?

A stairlift is cheaper in almost every case. A straight stairlift is £1,500 to £3,500 installed against £5,000 to £15,000 for an accessible downstairs shower room, and far more if an extension is needed. Moving downstairs wins on cost only when a stairlift would not be usable at all.

Can I get a Disabled Facilities Grant for a downstairs bathroom?

Yes, where an occupational therapist assessment supports it and your council approves the application. The grant covers changes that let you continue living at home, which includes downstairs bathing facilities. It is means-tested for adults and capped at £30,000 in England and £36,000 in Wales.

Do I need planning permission to convert a room into a bedroom?

Converting an existing room usually does not need planning permission, though building control may have something to say about means of escape and ventilation. An extension to create the space is a different matter, and while single-storey extensions often fall under permitted development rights, that depends on size, siting and whether the property is listed or in a conservation area. Check with your council before committing.

What happens to the upstairs if nobody uses it?

It still needs heating enough to prevent damp, and it still needs checking. Unused, unventilated rooms develop condensation and mould, and a leak in an empty house is found late. Keep the heating on low and have someone look round every few weeks.

Is a downstairs conversion better for someone with dementia?

Often yes, because it removes a staircase and a lift that both need to be used correctly. But it also moves a person out of a bedroom they know, which can be unsettling. This is a question for an occupational therapist who has met the person, not a general rule.

Can I do both?

Yes, and plenty of households do, in that order. A stairlift now buys time and costs little to reverse. A conversion later, when the need is clearer, is easier to plan and easier to fund with an assessment behind it.

Will a stairlift damage my stairs if I change my mind?

No. The rail fixes to the treads, not the wall, and removal leaves small screw holes that can be filled and covered by carpet. Removal costs £80 to £300.

Next steps

Ask for an occupational therapist assessment through your GP or your council’s adult social care team. It is free and it is what any grant application will rest on. While you wait, work out two things for yourself: whether you have a ground-floor room you are willing to lose, and where a shower room could go in relation to existing drainage. Those two answers usually settle the question before any builder arrives. Then get three quotes for whichever route the assessment supports, and check your grant position with the council before signing anything.
