The Honest Summary
If you want a garden that looks pristine year-round with zero effort, artificial grass will appeal to you. If you want a garden that functions well ecologically, performs better in the long term, and doesn't cost a small fortune to install, real turf is almost always the better choice.
Neither option is universally right. This guide lays out the real differences so you can make an informed decision.
Upfront Cost
Real Turf
A typical 50m² lawn using standard utility turf:
- Turf: £150–300 (£3–6 per m²)
- Ground preparation (materials): £100–200
- Labour if hiring: £400–800
- DIY total: £250–500
- Professional total: £650–1,100
Artificial Grass
A typical 50m² artificial lawn at mid-range quality:
- Artificial grass: £600–1,500 (£12–30 per m²)
- Base preparation (crushed stone, membrane): £300–600
- Labour: £500–1,000
- DIY total: £900–2,100
- Professional total: £1,400–3,100
Verdict: Real turf wins on upfront cost by a significant margin.
Ongoing Maintenance Cost
Real Turf
Annual maintenance costs for an established lawn:
- Fertiliser: £20–40/year
- Weedkiller: £10–20/year
- Scarifying/aerating (DIY): £0 if you own equipment
- Overseeding: £10–30/year
- Time cost: Approximately 2–4 hours per week during growing season (March–October)
Artificial Grass
Annual maintenance costs:
- Brush/clean: Time only
- Occasional disinfecting: £5–15/year
- Weed membrane maintenance: Occasional weed removal at edges
- Time cost: Approximately 30 minutes per month
Verdict: Artificial grass wins on maintenance time. Real turf wins if your time has low monetary value or you enjoy gardening.
Lifespan and Replacement
Real turf, properly maintained, lasts indefinitely. A well-established lawn can look excellent for 30+ years with no major renovation. Even if sections fail, you can overseed or relay specific areas cheaply.
Artificial grass has a lifespan of 10–15 years for mid-range products, 15–20 years for premium. After that, it needs full replacement — the same cost as the original installation.
Lifetime cost comparison (50m², 20 years):
- Real turf: ~£500 installation + ~£600 maintenance = £1,100
- Artificial grass: ~£1,750 installation + £250 maintenance + ~£1,750 replacement at year 15 = £3,750
Verdict: Real turf wins on lifetime cost in most scenarios.
Appearance
Real Turf
A well-maintained real lawn looks better than any artificial product. It has natural variation in colour, texture, and growth that no synthetic product can fully replicate. The downside: it can look patchy in winter, brown during drought, and worn in high-traffic areas.
Artificial Grass
Modern artificial grass looks remarkably convincing at a distance. Up close, or in direct sunlight, the synthetic appearance becomes obvious — particularly the uniformity and the sheen. The colour also fades over time, meaning a 10-year-old artificial lawn often looks noticeably duller than when installed.
Verdict: Real turf wins on appearance for most people, though this is subjective.
Temperature
This is one of the most significant practical differences that rarely gets discussed.
Real turf stays cool. Grass transpires — it releases moisture through its leaves, which cools the surface. On a hot summer day, a real lawn might be 20–25°C while the surrounding air is 30°C.
Artificial grass absorbs and retains heat. On the same 30°C day, artificial grass surfaces have been measured at 60–80°C. That's hot enough to cause burns on bare skin — a serious concern for young children and pets playing on the surface.
Verdict: Real turf wins decisively on temperature. This is a non-trivial concern for families with young children.
Drainage
Real turf, on well-prepared ground, drains well. Rainwater passes through the grass and into the soil, recharging groundwater and avoiding surface runoff.
Artificial grass requires a drainage layer beneath it, typically crushed stone over a permeable membrane. Done properly, drainage is adequate. Done poorly (or as it ages and the membrane degrades), it can become waterlogged and drain slowly.
Verdict: Real turf wins on drainage when properly installed.
Environmental Impact
Real turf provides genuine environmental benefits:
- Cools the local environment (urban heat island mitigation)
- Supports insects, birds, and soil microorganisms
- Sequesters small amounts of carbon
- Improves local biodiversity
- No plastic pollution
Artificial grass is made from plastic (typically polyethylene and polypropylene). At end of life, it typically goes to landfill — it's extremely difficult to recycle due to the mix of materials and the rubber infill. Research has raised concerns about microplastic particles from artificial grass washing into drains and waterways.
Several UK councils have introduced planning restrictions on front garden artificial grass due to environmental concerns. This trend is likely to continue.
Verdict: Real turf wins on environmental impact.
When Artificial Grass Makes Sense
Despite the above, artificial grass is the genuinely better choice in some situations:
- Heavily shaded areas where real grass simply won't grow
- High-traffic areas like play areas and dog runs that get used intensively all year
- People with genuine mobility limitations who can't maintain a real lawn
- Rental properties where a landlord needs a low-maintenance outdoor space
- Areas with persistent drainage problems that would kill real turf
The Bottom Line
For most UK homeowners with a standard garden, real turf is better on upfront cost, lifetime cost, appearance, environmental impact, and safety in hot weather.
Artificial grass is a reasonable choice in specific circumstances — persistent shade, very high traffic, or genuine inability to maintain a lawn. It's not a better product than real turf; it's a different product that makes sense in different contexts.
If someone is trying to sell you artificial grass on the basis that it will "save you money," ask them to show you the 20-year cost comparison.
