How long does artificial grass last? Real lifespans and what shortens them

Artificial grass is sold on the promise of no mowing for years, so the obvious question is how many. The honest answer depends less on the grass than on what it is laid on and how it is used, and the difference between a lawn that looks tired at year eight and one that looks new at year fifteen is mostly decided on installation day. This guide gives real lifespans for our ranges, what wears a lawn out, and how to get the long end of the range.

The short answer

A good artificial lawn lasts 15 to 20 years. Every range we sell carries a ten-year warranty against UV fade, and the pile is usually still upright and green well past that. The two things that shorten it are a poor base, which lets the surface move and puddle, and no infill or brushing, which lets a long pile flatten. Lay it on a compacted MOT and sand base, add kiln-dried sand, brush it a few times a year, and the lawn outlasts the fence it sits next to.

What "lasting" means for artificial grass

An artificial lawn does not fail suddenly. It ages in three ways: the fibres flatten under traffic, the colour slowly softens in sunlight, and the backing or joins can lift if the base beneath moves. A lawn is "worn out" when the pile no longer stands up after brushing and the walked-on routes look different from the rest. On a family lawn that is typically 15 years; on a lightly used front garden it can be 20 or more; on a dog run or a nursery playground that is walked on all day, 8 to 12.

What decides the lifespan

1. The base. 50mm of compacted MOT Type 1 topped with 25mm of sharp sand, with a weed membrane beneath, gives a firm, free-draining surface that never moves. Grass laid straight onto soil, or onto a base that was not compacted, develops dips, puddles and lifted joins within a couple of years and looks old long before the fibres are. This is the single biggest factor. The laying guide covers the base in detail.
2. Infill. 4 to 5kg per square metre of kiln-dried sand brushed into the pile weighs the grass down, protects the backing from abrasion and holds the fibres upright. A lawn with no infill flattens twice as fast.
3. Fibre shape and density. Flat, sparse fibres lie down and stay down. C-shaped and W-shaped fibres spring back, and a dense pile shares the load. Every range from Val 38mm upwards uses a shaped fibre; Dan is dense for its price and is what we recommend for a busy family lawn.
4. UV stabilisation. Cheap grass has UV protection sprayed on and fades in three or four summers. Ours is stabilised in the yarn and warrantied for ten years against fade.
5. Use. A lawn that is sat on and admired lasts longest. Dogs, football and a trampoline shorten it, and a shorter, denser pile copes better with all three.

Lifespan by range and use

Situation	Recommended range	Realistic life
Front garden, looked at more than walked on	Lux 30mm, Aris 40mm	18 to 20 years
Family back garden, children, occasional dog	Dan 38mm, Rum 40mm	12 to 15 years
Two or more dogs, daily use	Talya 30mm, Bul 35mm	10 to 12 years
Path, side return, dog run	Rocco 18mm	10 years

The maintenance that adds years

• Brush against the pile with a stiff broom every month or two. Two minutes, and it is what keeps a lawn looking new rather than flat.
• Top up the sand infill every couple of years where it has thinned on the walked routes.
• Rinse where the dog goes and treat with an enzyme cleaner monthly; smell is a drainage problem, not an age problem.
• Move heavy furniture and the trampoline occasionally so the pile recovers.
• Keep leaves off in autumn so nothing rots into the pile.

Against a real lawn, over fifteen years

A 30m² artificial lawn in Dan 38mm costs about £270 in grass and £500 to £1,000 laid yourself including the base. A real lawn costs a fraction of that on day one and then costs a mower, feed, weedkiller, water in dry summers, re-seeding of bald patches and roughly 40 hours a year for fifteen years. Over the life of the artificial lawn the real one costs more in products alone, before the time. The artificial versus real grass guide is honest about where real grass still wins.

When it does reach the end

The grass lifts off the base in a morning, the base underneath is reusable, and the new roll goes down on it the same day. Replacing an artificial lawn at year fifteen costs the grass and a day, not the groundwork, which is another reason the base matters more than the roll.

Frequently asked questions

How long does artificial grass last?

A good artificial lawn lasts 15 to 20 years. Every range we sell has a ten-year warranty against UV fade and the pile is usually still upright well past that. A busy dog run or nursery playground is nearer 8 to 12 years; a lightly used front garden can pass 20.

What makes artificial grass wear out faster?

A poor base, which lets the surface move, dip and puddle, and no sand infill or brushing, which lets a long pile flatten. Lay it on compacted MOT Type 1 and sharp sand, add 4 to 5kg of kiln-dried sand per square metre and brush it a few times a year.

Does artificial grass fade?

Cheap grass with UV protection sprayed on fades in three or four summers. Ours is UV-stabilised in the yarn and warrantied for ten years against fade; the colour softens very slowly over its life rather than changing.

Can artificial grass be replaced without redoing the base?

Yes. The grass lifts off in a morning, the base underneath is reused, and the new roll goes down the same day. Replacing a lawn at year fifteen costs the grass and a day, not the groundwork.
