The short answer
Good-quality artificial grass typically lasts 15–20 years in a UK domestic garden, with many products carrying 8–10 year manufacturer warranties. Lifespan depends far more on the sub-base and how much sun and traffic the lawn gets than on the grass brand alone. South-facing lawns and high-traffic areas wear first.
Lifespan is really two questions: how long the grass fibres stay upright and UV-stable, and how long the ground underneath stays flat. A premium grass on a poor base still fails early.

What shortens the life of a lawn
- Poor sub-base: ripples and sinking long before the fibres wear out.
- UV exposure: non-stabilised yarns fade and go brittle in strong sun.
- Heavy traffic: the same walked line flattens first.
- Heat sources: reflected light from glass or a nearby BBQ can melt fibres.
How to read a spec sheet
Three numbers tell you most of what you need: pile weight (grams per m² — higher is denser and more durable), pile height (30–40mm suits most gardens), and whether the yarn is UV-stabilised. A warranty is reassuring, but check what it actually covers and for how long.

Frequently asked questions
Does artificial grass fade in the sun?
Quality UV-stabilised grass resists fading for many years. Cheaper non-stabilised products can fade noticeably within a few summers, especially on south-facing lawns.
What's a good warranty for artificial grass?
Eight to ten years is common for mid-to-premium products. Read what it covers — usually fading and faults, not traffic wear or installation issues.
Can artificial grass melt?
The fibres can be damaged by concentrated heat, such as reflected sunlight from low-E glass or a barbecue placed directly on the lawn. Keep heat sources off the surface.
