Artificial Grass vs Real Turf: Comparison Guide

Summary

This is one of the most common domestic landscaping conversations in the UK, and it's frequently decided on price alone or on a customer's gut preference — both approaches miss the factors that actually determine whether the client will be happy with the result in five years. Artificial grass and real turf solve different problems and suit different gardens; recommending the wrong one is a common source of comeback complaints and poor reviews.

The core trade-off is maintenance versus authenticity and environmental performance. Artificial grass is a manufactured product: once installed correctly on a properly engineered sub-base, it needs almost no ongoing work — no mowing, no feeding, no watering, no mud in winter. Real turf is a living surface: it needs mowing every 1-2 weeks in the growing season, seasonal feeding and aeration, and reacts to weather (browning in drought, waterlogging in heavy rain, losing density in shade). For families with young children, dogs, low DIY interest, or a holiday-let/rental property where nobody will maintain a lawn, artificial grass often wins on lifestyle fit. For gardens used by wildlife-conscious households, larger plots where cost matters, or anywhere heat build-up and drainage are a concern, real turf usually wins.

There's also a growing planning and environmental dimension that didn't exist a decade ago. Local authorities increasingly discourage artificial grass in front gardens because of surface water run-off and biodiversity loss, and some tradespeople now face direct customer questions about microplastic shedding and the heat-island effect. This guide covers the technical comparison so you can give an informed recommendation rather than just installing what the customer asks for.

Key Facts

• Installed cost — artificial grass — £40-90/m² depending on grass spec, base build-up, and access (artificial grass pricing guide)
• Installed cost — real turf — £20-40/m² supply and lay on a prepared base; £8-15/m² turf-only where the ground is already prepared (turfing and lawn pricing guide)
• Lifespan — artificial grass — 10-15 years for quality product with correct aftercare; manufacturer warranty typically 8-10 years
• Lifespan — real turf — indefinite with correct maintenance (feeding, aeration, overseeding); a well-maintained lawn can outlast the house
• Sub-base — artificial grass — 50-100mm compacted MOT Type 1 or sharp sand, essential for drainage and longevity; skimping this is the single biggest cause of premature failure
• Sub-base — real turf — 100mm minimum topsoil to BS 3882:2015 grading; existing subsoil condition matters far more than for artificial grass
• Drainage — quality artificial grass backing drains 30-60 litres/m²/minute through perforations; real turf drains through the living soil profile and supports natural groundwater recharge
• Surface heat — artificial grass can reach 50-70°C in direct summer sun; real turf typically stays close to ambient air temperature and evaporatively cools the immediate area
• Shade tolerance — artificial grass performs identically in sun or shade (no growth requirement); real turf thins and fails in deep or permanent shade without specialist shade-tolerant seed mixes
• Maintenance — artificial grass needs occasional brushing, leaf/debris removal, and infill top-up; real turf needs mowing (weekly in growing season), feeding (2-4 times/year), scarifying, aerating, and overseeding
• Water use — artificial grass needs none after installation; real turf needs regular watering to establish and in dry spells, an increasing concern under hosepipe bans
• Biodiversity — real turf supports soil life, pollinators (if allowed to flower), and carbon sequestration in the soil; artificial grass is ecologically inert and can increase local run-off
• Microplastics — silica sand and rubber crumb infill on artificial grass can shed microplastic fragments over the product's life; this is an active area of environmental scrutiny
• Planning — front gardens — under Permitted Development, hard surfacing over 5m² in a front garden requires planning permission unless it is permeable or drains to a permeable area; artificial grass with an impermeable backing over a hard base can trigger this (suds regulations driveways)
• Planning — Conservation Areas — artificial grass may need consent if it materially changes the character of the area; check with the LPA
• Resale perception — mixed; some buyers value the low-maintenance appeal, others (particularly in premium/rural markets) see artificial grass as a negative

Detailed Guidance

When to recommend artificial grass

Artificial grass earns its premium in specific scenarios:

• Heavy footfall or dog traffic — real turf compacts and bares out under sustained heavy use (trampolines, dog runs, football goals); artificial grass tolerates this indefinitely
• Deep or permanent shade — under large trees or north-facing walled gardens, grass seed struggles regardless of mix; artificial grass is unaffected by light levels
• Awkward or small plots — narrow side returns, roof terraces, and balconies where mowing access is impractical
• Rental and holiday-let properties — no tenant or changeover cleaner will maintain a lawn to a consistent standard; artificial grass removes that variable
• Clients who have tried and failed with turf — patchy, weed-infested, or waterlogged lawns are a common trigger for the artificial grass conversation
• Time-poor households — genuinely a lifestyle product; be honest with clients that this is the main driver, not lower whole-life cost (see cost note below)

When to recommend real turf

Real turf is the better recommendation where:

• Budget is the primary driver — turf is roughly half the installed cost of artificial grass, with lower base-build requirements on already-reasonable ground
• The garden is large — the cost differential scales with area; on a 100m² lawn the gap between turf and artificial grass can be £2,000-5,000
• Wildlife and environmental performance matter to the client — increasingly common with younger homeowners and in areas with active "no mow May" or rewilding interest
• The plot gets good sun and reasonable drainage — turf performs best in typical open-garden conditions, which describes most UK back gardens
• The client is willing to do basic seasonal maintenance — mowing, feeding, and occasional aeration is not a large time commitment for most households (perhaps 20-30 minutes weekly in season)
• Resale value in a traditional or rural market — some buyers and estate agents still see a "proper lawn" as more desirable than artificial grass, particularly in villages and period-property markets

Whole-life cost — the conversation customers get wrong

Artificial grass is often sold on the promise that it "pays for itself" versus mowing costs and turf replacement. In practice the maths is close, not decisive:

• Artificial grass at £60/m² installed, replaced every 12 years, amortises to roughly £5/m²/year plus negligible maintenance
• Real turf at £30/m² installed lasts indefinitely but needs ongoing feed, occasional reseeding/patch repair, and either the homeowner's time or a lawn-care contract (£150-400/year for a modest garden) — amortised over 12 years this is broadly comparable, sometimes cheaper, sometimes more expensive depending on whether labour is self-provided

The honest framing for a customer: "Artificial grass costs more to install but nothing to maintain. Real turf costs less to install but needs regular attention. Over ten years the money is closer than either side of this argument usually admits — the real decision is how much time you want to spend on your lawn, and how the garden will actually be used."

Drainage and sub-base — where both options are commonly under-specified

Both products fail prematurely for the same underlying reason: inadequate ground preparation.

For artificial grass, a sub-base under 50mm, poor compaction, or missing weed membrane leads to rippling, poor drainage, and weed growth through the grass within 2-3 years. On clay soils or when converting an existing patio, drainage must be specifically engineered (perforated land drain under sub-base on clay; aggregate drainage layer over concrete) — see artificial grass for full sub-base specification.

For real turf, the common failure is laying turf directly onto poor or compacted subsoil without adequate topsoil depth (BS 3882:2015 recommends a minimum of 100mm quality topsoil) or without addressing existing drainage problems. Turf laid on waterlogged clay without remedial drainage will fail regardless of turf quality — see clay soil drainage and drainage landscaping.

Planning and environmental considerations

For most back gardens, neither option needs planning permission. The exceptions:

• Front gardens — under Permitted Development rules, hard surfacing exceeding 5m² requires planning permission unless it is permeable, or unless run-off drains to a permeable area rather than the highway. Artificial grass laid over an impermeable membrane and compacted base can be treated as a hard surface for this purpose in some LPA interpretations — check locally before quoting a front-garden artificial grass job
• Conservation Areas — artificial grass, particularly in a prominent front garden, can attract objection if it materially changes the character of a Conservation Area streetscene
• SuDS obligations — new-build developments and some larger domestic projects fall under Sustainable Drainage System requirements; an impermeable artificial grass installation over a hard base may need to demonstrate surface water management

Increasingly, some local authorities and housing associations are actively discouraging or restricting artificial grass on environmental grounds (heat-island effect, biodiversity net loss, microplastic run-off into watercourses). This is a live policy area and worth checking against current local planning guidance before quoting, particularly for larger commercial or multi-unit residential jobs.

Hybrid and middle-ground options

Where the customer is undecided, several options split the difference:

• Artificial grass in high-traffic zones only (dog run, play area) with real lawn elsewhere
• Wildflower or clover lawn — lower maintenance than traditional turf, better biodiversity than artificial grass, though less durable underfoot than either
• Reinforced/permeable turf (grass-reinforcement grid with real turf) for occasional-use areas like driveway verges, combining some durability of artificial with the natural surface of turf

Frequently Asked Questions

Does artificial grass really last 10-15 years?

With correct installation (adequate sub-base, correct tensioning, proper jointing) and reasonable aftercare (regular brushing, no direct heat sources like BBQs or reflected sun from windows, kept clear of sharp debris), 10-15 years is realistic for a quality mid-to-premium product. Budget grass with thin backing and low dtex density can fail in 5-8 years. The installation quality matters more than most customers expect — this is where a proper sub-base earns its cost.

Can artificial grass be installed over an existing lawn?

No — the existing turf and topsoil must be stripped out (typically to 50-100mm depth) and replaced with a compacted, free-draining sub-base. Laying artificial grass directly over grass or soft topsoil is the single most common cause of early failure: the base settles unevenly, drainage fails, and the grass ripples or ponds.

Will real turf survive under a trampoline or football goal?

Poorly, if used intensively. Grass under a stationary trampoline dies from lack of light within weeks; grass used as a regular football pitch bares out within a season from compaction and wear. For these specific high-wear zones, artificial grass (or a designated bark/rubber mulch play area) is the more durable recommendation, even if the rest of the garden is real turf.

Is artificial grass bad for the environment?

It has genuine environmental downsides compared with real turf: it doesn't sequester carbon, provides no habitat, increases surface run-off unless carefully drained, and can shed microplastic fragments (particularly from rubber crumb infill) over its service life. It is, however, more water-efficient (no irrigation) and eliminates the fuel/electricity use of regular mowing. Neither option is environmentally neutral — the honest comparison depends on what the customer weighs most heavily.

Do I need planning permission for artificial grass?

Not usually in a back garden. In a front garden, if the installation exceeds 5m² and does not allow water to drain to a permeable area, it can fall under Permitted Development hard-surfacing rules and require planning permission. Conservation Areas add further restriction. Always check with the client's local planning authority before a front-garden installation on a property in a sensitive area.
