Artificial Grass Installation Pricing UK: Labour & Margin

Quick Answer: UK artificial grass installation typically costs £40-90/m² installed, depending on grass spec, base build-up and access. Grass itself is £8-25/m² trade; the margin lives in the sub-base build (Type 1 MOT + granite dust or sharp sand bedding) which costs £12-25/m² in materials and 2-3 days labour per 50m². Watch CDM 2015 client duty on jobs over 30 days or 500 person-days, and avoid the common margin trap of under-quoting waste disposal of the existing surface.

Summary

Artificial grass has become a high-volume product for domestic landscapers since 2018-2022. The product quality has improved dramatically — modern recyclable polyolefin yarns at 35-45mm pile look genuinely lawn-like — and customers are willing to pay £3,000-6,000 for a back-garden install they expect to last 12-15 years. That should make it a great margin product. In practice, many installers under-price it because they look at the cheap grass on online merchants and quote against that, ignoring the genuine cost of base build, edging and labour.

This guide is for the small landscaping or general contractor who wants to add artificial grass to their offering. It covers the full cost stack, the productivity rates that actually work, the lifespan and aftercare commitments to make in writing, and the margin discipline that makes this a profitable add-on rather than a race to the bottom.

For natural turf alternatives see turfing and lawn pricing guide; the prep is broadly similar but artificial grass needs a finer, harder, better-drained base. For drainage decisions see permeable paving and suds and surface water.

Pricing assumes good access, no significant levels work, no tree roots requiring excavation, and standard pet/family use. Add 20-30% for difficult access, 30-50% for levels work, and a premium for intricate shapes with multiple cuts.

Detailed Guidance

Cost components broken down

A correctly-priced artificial grass quote separates seven cost elements:

1. Site clearance — strip existing surface
2. Excavation — dig out to required depth (typically 100-130mm below FFL)
3. Sub-base — Type 1 MOT supply, lay and compact
4. Laying course — granite dust or sharp sand screed
5. Edging — perimeter restraint (timber, concrete, metal)
6. Grass supply and fit — including seam tape, adhesive, pins
7. Infill and finish — kiln-dried sand brushed in, final groom

Pricing the grass and labour only and absorbing 1-5 is the route to losing money. On a 50m² back garden install, the base build commonly takes 1.5-2 days for a two-person team; the grass laying itself takes half a day. The customer doesn't see the base build but it is the bulk of the job.

Choosing the grass

The wholesale market splits into three tiers:

Pet-friendly products with anti-bacterial backings and integrated drainage holes carry a £3-5/m² premium and are worth specifying for any household with dogs.

Mono-material recyclable grass is a sales argument worth making — customers increasingly ask about end-of-life recycling. Mono-material PE grass can be recycled at end-of-life through manufacturer take-back schemes; mixed-material PE/PP/latex grass currently cannot.

Base build — where the margin lives

The base is the single most important factor in install quality and lifespan. Get it wrong and the grass settles, becomes uneven, fails to drain, and the customer is back within 18 months.

Standard build-up for a typical clay or compacted-soil site:

Topsoil/turf strip                       50-100mm
Membrane (optional weed barrier)         Type 1 separation
Type 1 MOT sub-base                      50-75mm compacted
Granite dust laying course              25-40mm screeded
Grass + infill                          35-45mm + sand
                                        ---------
Total build-up below FFL                ~120-160mm

For free-draining sandy sites the Type 1 layer can be reduced to 40mm. For boggy clay sites, increase the Type 1 to 100mm and consider an aco drain to a soakaway. Never lay grass directly onto excavated subsoil — it will undulate within 12 months.

Compaction matters. A wacker plate (vibrating compactor) is essential — hand-tamping is not enough. Two passes per layer minimum. Check level with a long straight edge before laying course goes down.

Edging and detail

Pressure-treated 100×50mm timber pegged into the ground with 25×38mm timber pegs every 600mm is the cheapest perimeter — £4-6/lin m material. Concrete kerb upstands look smarter and last longer — £10-18/lin m material. Steel edging is the premium option — £15-25/lin m and shows a clean visible line.

Around trees and protrusions, use galvanised washer-headed screws into the timber edging and tuck the grass edge down. Around hard surfaces (patio, decking) the grass needs to terminate against either a 50×50mm timber rail or an aluminium L-trim.

Seams and joining

Seams are where bad installs are spotted. Best practice:

Step 1: Lay both grass pieces with the pile in the SAME direction
        (always; the most common install error is alternating direction)

Step 2: Trim factory edge off both pieces with sharp Stanley knife
        from the BACK; cut between 3 yarn rows

Step 3: Lay 300mm seam tape under the joint, smooth side up

Step 4: Apply two-part polyurethane seam adhesive in a zig-zag

Step 5: Roll both grass edges onto the tape, butt cleanly,
        weight with sand bags or boards for 24h

Step 6: Brush against the pile across the seam with a stiff brush
        to lift any flattened yarn over the joint

Get the pile direction wrong and the seam shows like a stripe under sunlight forever. There is no fix short of replacement.

                                                    (~£101/m²)

This is at the premium end. A standard grass on the same garden lands around £75/m². A budget all-in price under £55/m² requires cutting corners on the base build — and the resulting install fails inside 2-3 years.

Margin traps

The errors that consistently catch out installers new to artificial grass:

  1. Quoting against online merchant prices. £15/m² for grass online is true but it's a single-tone PP yarn that won't last. Compare like for like.
  2. Skipping the laying course. Type 1 alone is too coarse for a flat finish — you'll get bumps and pinch points showing through. The 25-40mm sand or dust layer is non-negotiable.
  3. Wrong pile direction on seams. Permanent visible defect. Always check before cutting.
  4. No drainage strategy on clay. "It'll drain through the perforated backing" — yes, but to what? If the sub-base is sat in clay, water pools. Specify a soakaway or aco connection on heavy sites.
  5. Under-pricing waste removal. A 50m² turf strip is 5-7 tonnes of soil and turf. That is an 8-yard skip or multiple loads.
  6. No written aftercare. Pet waste removal, monthly brushing, sand top-up — all the customer's responsibility, in writing. Otherwise a flattened pile becomes your problem.

Aftercare

Modern grass needs less care than natural lawn but it is not zero-care. Standard customer brief:

Quality grass with this care lasts 12-15 years. Without brushing, pile flattens permanently in high-traffic zones inside 3-4 years.

Frequently Asked Questions

Do I need planning permission?

Generally no for replacing an existing soft-landscaped area in a private garden. Front gardens larger than 5m² where artificial grass is being installed in lieu of a permeable surface may engage the Front Garden Planning (Town and Country Planning) requirements introduced in 2008 — if the surface is not permeable to a soakaway. Artificial grass on a Type 1 MOT base over clay is generally treated as permeable enough but check the specifics with the local authority on borderline cases.

Is artificial grass classed as SuDS-compliant?

It's a grey area. Quality grass with perforated backing on a Type 1 MOT base drains rapidly but the system is not formally classified as a SuDS feature. Where SuDS compliance matters (e.g. larger paved-area conversions), specify a soakaway and document the drainage path. See suds and surface water.

How long does an install last?

Quality grass: 12-15 years. Budget grass: 4-7 years. Base build properly compacted: indefinite. Base build poorly compacted: undulations show within 18 months regardless of grass quality.

Can I lay it in winter?

Yes, but base build is slower in wet conditions and the adhesive cures slower below 5°C. Use a winter-grade two-part PU adhesive. Avoid laying in frost.

What about fire risk?

Quality grass is fire-rated (typically Cfl-s1 per EN 13501-1). Avoid BBQs directly on the grass — embers melt yarn permanently. Specify a paving section for grills in the design.

Is it VAT-zero on a new build?

For genuine new-build dwellings through the main contractor, soft landscaping (which artificial grass arguably is, despite being synthetic) can qualify under HMRC VAT Notice 708 Group 5 Schedule 8. For replacement on an existing dwelling, standard 20% applies. See vat for tradespeople for the detail.
