Stair Carpet Fitting Costs UK — What to Charge to Carpet Stairs in 2026

Quick Reference: Stair Carpet Fitting Prices UK 2026

Whole-house supply-and-fit ranges so widely because the carpet grade is the biggest variable — a budget polypropylene at £8/m² versus an 80/20 wool twist at £30/m² changes the materials bill more than the labour ever will. Quote the labour and materials as separate lines so the customer can see exactly what they're paying for and trade up or down on carpet grade without you having to re-quote the whole job.

How Stair Carpet Is Priced

There are three common ways fitters price stairs, and most experienced fitters use a blend depending on the job. Understanding all three lets you sanity-check your number from more than one angle before you commit.

• Per step: The simplest method. Count the steps and multiply by a per-step rate of £8–£15. A standard 13-step flight at £10 per step gives you £130 labour. This works well for straight flights and is easy to explain to customers, but it under-rewards you on winders unless you charge a higher rate for turning steps.
• Per flight: A flat fee for the whole staircase — £80–£150 for a typical straight flight, more for landings and turns. Quick to quote on site, and lets you build in a margin for the fiddly bits without itemising every step.
• Per m² with a stair uplift: You calculate the area as you would for a room, then apply a labour multiplier because stairs take far longer per square metre than flat floors. A common rule of thumb is to charge stairs at 2–3× the per-m² labour rate you'd use for an open room. This is the most defensible method on bigger supply-and-fit jobs where the customer is comparing carpet grades.

Whichever method you lead with, always cross-check against your day rate. If a job will take you most of a day, the quote needs to clear your £150–£250 day rate after materials — if a per-step calculation comes out below that on a job that's clearly half a day or more of work, the per-step rate is too low for that staircase.

Straight Stairs vs Winders and Turns

The single biggest driver of stair labour cost is whether the staircase is straight or has winders. A straight flight is repetitive, predictable work — you can develop a rhythm and move quickly. The carpet runs as a continuous length down treads and risers, you bang it into the gully behind each nosing with a bolster, and the steps are all the same width.

Winders — the wedge-shaped steps that take the staircase around a turn — are a different job entirely. Each winder is a different shape, the carpet has to be cut and seamed to follow the angle, and getting a clean, wrinkle-free finish around the turn is genuinely skilled work. A single set of three winders can add as much time as half a straight flight. Quarter-turn and half-turn landings, kite winders and bullnose bottom steps all add cutting and fitting time on top.

This is why labour for winder stairs (£150–£300) sits well above a straight flight (£80–£150). If you price winders at the same per-step rate as straight treads, you will lose money every time. The practical fix: either charge winder steps at double your straight per-step rate, or quote winder staircases as a flat per-flight fee that bakes in the extra time. Never quote winders sight unseen over the phone.

Runners vs Full-Width Fitting

Full-width fitting — carpet wall-to-wall across the whole stair — is the standard domestic job and what most of the pricing above assumes. A stair runner is a narrower band of carpet down the centre of the stairs with the wood exposed either side, usually held with stair rods.

Runners can look deceptively quick because there's less carpet, but they are often more fiddly, not less. You need accurate, symmetrical margins on both sides of every step, the edges have to be neatly finished or whipped, and any stair rods or fixings add fitting time. Customers also expect a premium, hand-finished look from a runner. Don't discount a runner just because it uses less material — price the labour on the time and precision it demands, which is often equal to or above a full-width fit. Factor in the cost of stair rods, brackets, and edge binding as separate material lines.

What's Included — And What Should Be a Separate Line

Disputes on stair jobs almost always come from a vague quote. Be explicit about what your price covers. A clear stair fitting quote should state which of the following are included and which are extra:

• Underlay: Stairs need a dense, hard-wearing underlay — a cheap room underlay will bottom out on the nosings within months. Add £3–£6 per stair / per m² for a suitable PU or crumb underlay.
• Gripper rods: Stairs use gripper top and bottom of each riser to hold the carpet tight into the gully. This is consumable cost plus fitting time — include it explicitly.
• Door bars / threshold strips: Where the landing meets a bedroom doorway or the hall meets the front door, you'll fit a transition bar. Price each one.
• Uplift and disposal of old carpet: Pulling up old stair carpet, removing old gripper and tack strip, and disposing of the waste is real time and a tip run. Charge for it — typically £30–£80 depending on volume and whether you need a waste licence run.
• Moving furniture: Clearing the landing and hall before you start. Fine for a couple of items; flag it as extra if the customer expects you to empty a fully furnished space.

Itemising these protects your margin and your reputation. A customer who sees "uplift and disposal of old carpet — £50" on the quote won't be surprised by it, and you won't be tempted to swallow it to keep the peace.

Carpet Types and Grades for Stairs

Stairs are the highest-wear surface in any home — every footstep concentrates on the nosing of each tread. That means carpet choice matters more on stairs than anywhere else, and you should steer customers away from grades that won't last.

• Wool and wool-blend (80/20) twist: The premium choice. Resilient, springs back from crushing, ages well and looks the part on a feature staircase. Expect £20–£40/m². Best on the nosings where crush resistance matters most.
• Polypropylene: Budget-friendly, stain-resistant and easy to clean, but it crushes and flattens faster on stair nosings than wool. Fine for rentals and lower-traffic homes; expect £6–£15/m². Steer customers toward a heavier weight if they go polypropylene on stairs.
• Polyamide / nylon and twist piles: A strong middle ground — durable, good crush recovery, available in twist constructions that hide footmarks well on stairs. £12–£25/m².

Always check the carpet's wear rating. Look for a heavy domestic or extra-heavy domestic rating for stairs — a light or medium domestic carpet will look tired on the nosings within a year or two, and the customer will remember who fitted it. A twist or textured pile also hides footprints and vacuum marks far better than a smooth velvet, which shows every step on a staircase.

What Drives the Cost Up

Two staircases with the same number of steps can be wildly different jobs. These are the factors that add time and should push your quote toward the top of the range:

• Winders and turns: As covered above, the single biggest cost driver. Every turning step is bespoke cutting and fitting.
• Spindles and balustrade: A staircase open on one side with spindles means cutting the carpet neatly around the base of every spindle and the newel post. This is slow, precise work — far more than a closed staircase boxed in by walls on both sides.
• Access and obstructions: A tight hallway, a low ceiling over the stairs, an under-stairs cupboard door to work around, or a narrow turn at the bottom all slow you down.
• Pattern matching: Striped or patterned stair carpet has to line up across treads and risers. Pattern repeat adds cutting waste and significant fitting time — quote a meaningful uplift for it.
• Bullnose and curved steps: A rounded bottom step or a curved bullnose tread needs the carpet cutting and easing around the curve — fiddly and time-consuming.

Worked Example: Straight Flight + Landing

Take a typical job: a 13-step straight flight plus a small landing, supply and fit, in a mid-range polyamide twist. Here's how the numbers stack up so you can see where the margin sits.

• Carpet: Stairs and landing need roughly 8m² of carpet allowing for the tread/riser run and cutting waste. At £15/m² trade that's £120, retailed to the customer at £20/m² = £160.
• Underlay: 8m² of stair-grade underlay at £4/m² = £32 cost, charged at £48.
• Gripper, door bar, sundries: roughly £20.
• Uplift and disposal of old carpet: £50.
• Labour: Straight flight plus landing, around half a day — £180 (comfortably above the £150 floor of your day rate for half a day of skilled work plus mobilisation).

That gives a customer-facing total of around £458, sitting neatly inside the £400–£1,200 whole-house band for a modest spec. Your materials margin is around £56 and your labour clears your day rate — a healthy, defensible job. Bump the carpet to an 80/20 wool twist and the same job comfortably pushes past £650 without any extra labour, which is exactly why you quote materials and labour as separate lines.

How to Quote Stairs Profitably

The fitters who make money on stairs do three things consistently. First, they always survey winder and open-spindle staircases in person — never quote a turn or a balustrade off a phone description. Second, they separate labour and materials on the quote so the price holds up when the customer compares carpet grades, and so a trade-up doesn't silently eat their labour margin.

Third, and most important: they refuse to price winders like straight treads. The most common way to lose money fitting stairs is to count steps, multiply by a flat per-step rate, and forget that three of those steps are winders that'll take as long as the other ten combined. Either charge turning steps at double, or quote the whole staircase as a flat fee with the fiddle built in. Cross-check every stair quote against your day rate before you send it — if the number doesn't clear £150–£250 for a day's work after materials, it's too low, however reasonable the per-step maths looked.
