Artificial grass installation has a low barrier to entry as a trade — anyone can buy a roll, hire a plate compactor, and call themselves an installer. The quality difference between a good and a bad artificial grass job isn't always obvious on the day, but it shows within two years: edges lifting, surfaces draining poorly, infill compacting unevenly, or the grass itself wearing in heavy traffic areas.
If you're considering artificial grass for your Leicester garden, here's what to look for, what to ask, and what should make you walk away.
What Actually Makes a Good Artificial Grass Installation
The grass itself is almost secondary. The sub-base is what determines how well the lawn performs and how long it lasts. A good installation requires:
Correct excavation depth
75–100mm of topsoil removed, more on Leicester's clay-heavy ground. Clay doesn't drain naturally — if you lay sharp sand over clay without a drainage layer, you'll have a waterlogged lawn within the first wet winter.
MOT Type 1 or sharp sand sub-base
Compacted in layers using a vibrating plate. This creates the firm, level surface that the grass is laid onto. An uncompacted sub-base will develop lumps and dips as it settles — visible through the grass within months.
Weed membrane
A commercial-grade membrane, not garden centre fabric. Laid over the compacted sub-base before the grass goes down. The membrane stops weed growth from below without impeding drainage.
Secure edging
The perimeter of the lawn needs a fixing system — either a timber baton spiked into the sub-base or a purpose-made aluminium edging strip. Without this, grass edges lift in Leicester's freeze-thaw winters.
Proper jointing on large lawns
Any run wider than the grass roll (typically 4m) needs a join. A good join is invisible. A bad join is a visible line across your lawn that never goes away.
Grass Specification: What to Ask For
Not all artificial grass is equal. Ask your installer to provide the product specification sheet for what they're proposing. Things to check:
Pile height: 30–40mm is the sweet spot for a realistic look in a residential garden. Under 25mm looks commercial and flat; over 45mm flops over and can trap debris.
Dtex (fibre weight): A measure of how much material is in the fibres. 10,000–14,000 dtex is a good residential spec. Cheaper grasses use less material per fibre — they look fine initially but flatten faster under use.
Drainage rate: Should be minimum 60 litres per square metre per hour. On Leicester's clay sub-base (even with the correct preparation), adequate drainage rate in the grass itself matters.
UV stabilisation: All outdoor artificial grass should be UV stabilised. Ask for this confirmation — cheaper imported products can fade and discolour within 2–3 years of UK sun exposure.
Guarantee: Any reputable grass should carry an 8–10 year manufacturer guarantee against UV fade and fibre breakdown. Get this in writing before committing.
Red Flags When Getting Quotes
No site visit
A proper artificial grass quote requires seeing the ground conditions, measuring accurately, and assessing drainage. Any quote given over the phone or from photos alone can't account for what's actually under the surface.
Suspiciously low price
Quality artificial grass costs £15–£30/m² in materials alone. If a quote for supply and install comes in at £25/m² all-in, either the grass is low-grade or the sub-base prep is minimal.
Vague about the sub-base
Ask specifically: "What depth are you excavating to and what are you laying under the membrane?" If the answer is vague or "we'll assess on the day," push for a written spec before signing anything.
No fixed price
Reputable installers will give you a fixed price for the complete job. "Day rate plus materials" for a straightforward residential lawn isn't appropriate — it removes any accountability for efficiency.
No examples of completed work
Ask for photos or addresses of previous Leicester installations you could drive past. Anyone doing good quality work in Leicestershire will have a portfolio.
Questions to Ask Every Installer
- What depth are you excavating to, and what sub-base material are you using?
- What's the drainage rate of the grass you're proposing?
- What pile height and dtex rating is the grass?
- What does the manufacturer's guarantee cover, and for how long?
- How do you handle joins on wider lawns?
- Is edge fixing included — timber baton or aluminium system?
- Do you remove and dispose of existing turf, or is that extra?
Artificial Grass on Leicester Clay Soil
This is specific to our area. Leicester's clay soil doesn't drain freely — it holds water in winter and shrinks in dry summers. For artificial grass to perform on clay, you need:
- Full excavation of the clay down to a consistent depth (minimum 75mm, ideally 100mm)
- A layer of clean angular sub-base stone (MOT Type 1) compacted in stages
- In particularly waterlogged gardens, a perforated land drain running to a soakaway before the sub-base goes in
Installers who lay artificial grass directly on top of existing clay topsoil — even with membrane — will produce a waterlogged lawn within the first winter. It's the most common failure mode we see when customers come to us for remedial work.

Frequently Asked Questions
How much does artificial grass cost to install in Leicester?
Typically £45–£75/m² fully installed, depending on grass grade and sub-base requirements. A 30m² rear garden runs £1,400–£2,300. The wide range reflects grass quality and what's underneath — clay soil requiring deeper excavation costs more than well-drained ground.
How long does artificial grass last in Leicester?
A professionally installed artificial grass lawn typically lasts 15–20 years or more. The grass itself usually comes with an 8–10 year manufacturer guarantee against UV fade and fibre breakdown. The sub-base, if built correctly, doesn't degrade.
Does artificial grass get hot in summer?
Yes — all artificial grass heats up in direct sun, more so than natural turf. Modern grass products with cooling infill (silica sand or cork) mitigate this. In a north-facing or partially shaded Leicester garden, this is rarely an issue.
Can artificial grass be laid over existing concrete or paving?
Yes, in some cases — if the existing surface is level, drains adequately, and is structurally sound. We assess on site. Laying over old concrete can reduce excavation costs but isn't always the best approach if the drainage profile is poor.
Is artificial grass suitable for dogs in Leicester gardens?
Yes — pet-friendly artificial grass with an antimicrobial backing and adequate drainage is well-suited to dogs. The key is drainage rate and regular hosing down. We'd recommend a grass with minimum 60 litres/m²/hour drainage rate for pet use.
