The short answer
Price differences in artificial grass usually reflect real differences in build quality. A premium grass tends to have higher density and face weight, a quality polyethylene face fibre, a realistic multi-tone colour with a thatch layer, strong UV stabilisation so it resists fading, a durable permeable backing, and a longer manufacturer warranty. A cheap grass typically has lower density, more visible backing, a flatter colour, weaker UV protection that fades sooner, and a shorter or no warranty. The honest rule is to spend on the grass for areas you use and see daily, where realism and durability matter, and consider a mid-range product for low-use or temporary spots. Because installation costs the same regardless of the grass, fitting a cheap grass that needs replacing sooner is often false economy — the labour is paid twice.
Artificial grass spans a wide price range, and it is not always obvious what the extra cost buys. Here is what genuinely separates budget from premium grass, and how to decide where to spend.

What separates cheap from premium grass
The biggest differences are in the specification. Premium grass packs in more fibres — higher density and face weight — so it looks fuller, hides its backing and resists flattening. It uses a quality polyethylene face for a soft, realistic feel, a varied colour with a thatch layer for natural looks, and strong UV stabilisation so it holds its colour for years rather than fading or greying. The backing is more durable and reliably permeable, and the product usually comes with a longer warranty.
Cheap grass cuts these corners. Lower density shows the backing and flattens faster, the colour is often flatter and brighter, the UV protection is weaker so it fades sooner, and the warranty is short or absent. From a distance, a budget grass can look acceptable when new, but it tends to age faster and less gracefully than a premium one, especially in a sunny, well-used garden.
| Attribute | Cheap grass | Premium grass |
|---|---|---|
| Density / face weight | Lower | Higher |
| Face fibre | Often basic | Quality polyethylene |
| Colour and thatch | Flatter, may lack thatch | Multi-tone with thatch |
| UV stability | Weaker, fades sooner | Strong, holds colour |
| Backing | Thinner | Durable, permeable |
| Warranty | Short or none | Longer |
| Ageing | Flattens and fades faster | Holds appearance longer |

Why installation cost changes the maths
The crucial point many people miss is that installation costs the same whatever grass you lay. The excavation, base, membrane, laying course and labour are unchanged whether the grass on top is budget or premium. So if a cheap grass wears out or fades in a handful of years and a premium one lasts much longer, fitting the cheap one means paying for the whole installation again sooner.
That makes a low headline grass price misleading. The sensible way to compare is the total cost over the expected life of the surface, including the likelihood of replacement. For an area you will keep for many years, spending more on a durable grass often works out as the better value, because it spreads the unchanged installation cost over a longer life.
Where to spend and where to save
The practical answer is to match the grade of grass to how the area is used. For the main lawn you walk on, look at and use every day, a quality grass with good density, a realistic colour, strong UV stability and a solid warranty is worth the extra, because realism and durability matter most there. This is where a premium product pays back.
For low-use or short-term areas — a rarely walked corner, a temporary surface, a rental where you will not stay long — a mid-range grass can be perfectly sensible, and there is little point paying top prices. The skill is not in always buying the dearest or the lowest-priced, but in reading the specification, judging samples in your own daylight, and choosing a grade that suits both the use and how long you intend to keep it.
How to compare products fairly
Comparing grasses on price alone is misleading, because the price per square metre is only meaningful against the specification behind it. To compare fairly, line up the figures that matter side by side: pile height, density and face weight, the face fibre material, whether there is a thatch layer, the UV stabilisation, the backing type and the length of warranty. A grass that looks dearer per square metre can be the better value if it has a markedly higher face weight, stronger UV protection and a longer guarantee than a cheaper rival. Two products at very different prices are often simply different grades, not the same grass at different margins.
Samples are essential to this. Order physical samples of any grasses on your shortlist and assess them together, outdoors, in your own garden's light. Compare them for colour realism, density when you part the fibres, how quickly they recover when pressed, the presence and quality of the thatch, and how natural they look from standing height. This hands-on comparison reveals differences that no specification sheet fully captures, and it stops a glossy product photo or a low headline price from driving the decision.
Finally, factor in the warranty and the supplier as part of the value, not an afterthought. A longer manufacturer warranty signals confidence in the product's durability and UV stability, and buying from an established supplier means the warranty is more likely to be honoured. Weighing the whole picture — specification, sample, warranty and the unchanging installation cost — gives a far truer sense of value than the price tag alone. Done this way, the question of cheap versus premium resolves itself into a more useful one: which grade genuinely suits this area, this length of stay and this budget, judged on evidence rather than on price or marketing.
To bring it together, the price of artificial grass broadly tracks its build quality — density and face weight, fibre and colour, UV stability, backing and warranty — so a higher price usually buys a grass that looks more realistic and lasts longer. Because the installation cost is the same whatever grass sits on top, the fair comparison is whole-life cost, not price per square metre, and that often favours a durable grass for an area you will keep for years. Spend where it shows and gets used daily, save on low-use or short-term spots, compare specifications and samples side by side, and let the evidence rather than the headline price decide.
Frequently asked questions
Is expensive artificial grass worth it?
For a main lawn you use daily, usually yes. Premium grass has higher density, better UV stability and a longer warranty, so it looks more realistic and lasts longer. Because installation costs the same whatever grass you lay, a durable grass often gives better value over its life than a cheap one that needs replacing sooner.
Why is some artificial grass so cheap?
Budget grass cuts cost through lower density, basic fibres, flatter colour, weaker UV protection and a thinner backing, often with little or no warranty. It can look acceptable when new but tends to flatten, fade and age faster, especially in sun and heavy use. The low price reflects lower build quality.
Does cheap artificial grass fade quickly?
It is more likely to. Cheaper grass often has weaker UV stabilisation, so it can fade or grey faster under sunlight than a premium product with strong UV protection. If long-term colour matters, check the manufacturer's information on UV resistance and colourfastness rather than choosing on price alone.
