Stairs take more punishment than any other carpeted surface in a home. Every step compresses the pile, bends the backing, and wears fibres in the same tight spot thousands of times a year, so the wrong choice can look worn out within a couple of years. This guide covers which carpets actually last on stairs and why.
What Is the Best Carpet for Stairs?
The best carpet for stairs is a dense wool or 80/20 wool-nylon twist pile with a Class 23 heavy domestic rating or above, fitted over a good-quality underlay. Wool provides natural resilience and bounces back after being compressed, while the nylon component adds abrasion resistance at the high-wear stair edges.
Why Pile Type Matters More Than Colour
A twist, or cut pile, carpet generally outperforms a loop pile carpet on stairs for most households, since twist pile has no exposed loops to snag on shoe heels or pet claws. The exception is a very tightly woven loop carpet, such as Berber, which can perform well if the loop density is high enough. Loose loop carpets, however, are more prone to snagging and pulling, which quickly damages both the appearance and structure of the carpet.
Understanding Carpet Ratings
UK carpets are rated for suitability by use, following the EN 1307 standard. A Class 22 carpet is intended for general domestic use, such as bedrooms, and will typically fail on stairs within around 24 months as the fibres flatten and the backing starts to show through. Class 23, described as heavy domestic, is the minimum standard worth considering for a UK staircase used daily, and an extra heavy domestic rating offers even greater durability for particularly busy households.
Comparing Carpet Materials for Stairs
| Material | Durability | Best for |
|---|---|---|
| 80/20 wool-nylon twist | Very high, 10 to 15 years | Most family homes wanting the best all-round performance |
| 100% wool | High, naturally resists flattening | Households prioritising comfort and appearance, willing to pay more |
| Polypropylene | Moderate, can flatten unless very short pile | Budget-conscious households, bleach-cleanable option |
| Sisal (natural fibre) | Very high, extremely hard-wearing | Households wanting a natural look, though harder underfoot |
What Affects Cost
Stair carpet in the UK typically costs £6 to £60 per square metre, depending on material and quality, with fitting for a straightforward straight staircase adding roughly £80 to £120 in labour. Stairs with turns, landings, or extra fittings such as stair rods will cost more to fit than a simple straight run.
Practical Buying Tips
- Pair with quality underlay: a dense PU foam or rubber underlay, fitted using the wrapover method around the stair nosing, significantly extends carpet life.
- Choose mid-tone or patterned carpet: heathered shades and subtle stripes disguise everyday marks and wear better than very light or very dark plains.
- Avoid loop pile with pets: claws can catch on exposed loops, causing pulls that quickly damage the carpet’s appearance.
- Check the nosing performance: the edge where tread meets riser takes the most compression, so a carpet’s stated durability rating matters more here than anywhere else in the home.
- Consider a stair runner: if you want to keep wooden treads visible, a runner offers noise reduction with a more decorative finish, often paired with traditional or contemporary stair rods.

Frequently Asked Questions
What carpet rating do I need for stairs?
Look for a Class 23, heavy domestic rating or above under the EN 1307 standard. A Class 22 carpet, intended for general domestic use, typically wears out on stairs within about two years.
Is wool or polypropylene better for stairs?
Wool, particularly an 80/20 wool-nylon blend, generally outperforms polypropylene in appearance retention and durability, though polypropylene is more budget-friendly and often bleach cleanable, which suits households with young children.
Should I avoid loop pile carpet on stairs if I have pets?
Yes, in most cases. Pet claws can catch on exposed loops, causing snags and pulls. A tight twist, or cut pile, carpet is generally the safer choice for households with cats or dogs.
How much does it cost to carpet a staircase in the UK?
Carpet typically costs £6 to £60 per square metre, with fitting labour for a straightforward straight staircase adding around £80 to £120, though stairs with turns or landings cost more to fit.
How long should a good stair carpet last?
A quality wool or wool-blend carpet, correctly fitted with good underlay, typically lasts 10 to 15 years on stairs, while a lower-grade carpet may need replacing within just a few years under the same daily use.
