Artificial grass has become a staple for UK homeowners seeking a lush, mud-free lawn year-round. In a climate where natural grass often struggles with waterlogg...
However, the longevity of an artificial lawn depends almost entirely on the quality of the groundwork. A professional installation ensures proper drainage and a level finish that won't sag or ripple over time, protecting your investment for years to come.
What Does the Work Involve?
- Site Survey: Measuring the area, checking ground levels, and identifying existing drainage issues.
- Excavation: Removing existing turf and soil to a depth of roughly 75mm–100mm to make room for the new base.
- Edging Installation: Fitting timber, composite, or metal edging to secure the turf perimeter.
- Sub-base Construction: Laying and compacting a layer of MOT Type 1 or crushed granite to create a stable, porous foundation.
- Membrane Application: Installing a heavy-duty geotextile weed membrane to prevent growth while allowing water to pass through.
- Laying and Joining: Rolling out the turf, precision-cutting the edges, and securing seams using specialist outdoor adhesive and jointing tape.
- Finishing: Applying kiln-dried sand infill and using a power brush to lift the pile for a natural appearance.
Typical Costs
Prices for artificial turf installation vary based on the quality of the grass selected and the complexity of the ground preparation. Expect to pay more if access is restricted or if significant drainage work is required.
| Item / Project Size | Low £ | High £ | Notes |
|---|---|---|---|
| Small Garden (approx. 20m²) | £1,200 | £1,800 | Includes basic ground prep and mid-range turf. |
| Medium Garden (approx. 40m²) | £2,400 | £3,600 | Standard residential installation inc. waste removal. |
| Large Garden (approx. 70m²+) | £4,500 | £7,000+ | Higher material volume and multi-day labour. |
| Premium Turf (Supply only) | £25 | £45 | Per square metre for 35mm-40mm pile height. |
| Waste Disposal (Skip hire) | £250 | £450 | Depends on soil weight and skip size (6-8 yard). |
Labour typically accounts for 40-50% of the total cost. Factors such as "pet-friendly" polyurethane-backed turf or specialist "shock pads" for play areas will increase the final quote.
How Long Does It Take?
- Small Gardens (under 20m²): 1 working day.
- Medium Gardens (20m² – 50m²): 1.5 to 2 working days.
- Large or Complex Gardens (50m²+): 3 to 5 working days.
- Factors affecting duration: Heavy rain, restricted access (e.g., through a terraced house), and the volume of soil to be manually excavated.
DIY or Professional?
While laying the turf itself looks simple, the "heavy lifting" phase is where most DIY projects fail. Removing several tonnes of soil and replacing it with compacted aggregate requires significant physical effort and specialist machinery like plate compactors.
Professional installers ensure the seams are invisible and the drainage is SUDS-compliant, preventing your garden from becoming a swamp during a British downpour.
If you have pets, professional installation is highly recommended to ensure the correct sub-base (usually a "grano" dust rather than sand) is used to prevent urine odours from being trapped.
Choosing the Right Tradesperson
- Check Memberships: Look for landscapers registered with the Association of Professional Landscapers (APL) or the British Association of Landscape Industries (BALI).
- Verify Waste Handling: Ensure they hold a valid Environment Agency Waste Carrier Licence to dispose of your old turf legally.
- Review Portfolios: Ask for photos of "joins" specifically; a good installer makes these impossible to spot.
- Ask these questions:
- How deep will the sub-base be, and what materials are you using?
- Do you use timber or composite edging? (Composite lasts longer).
- What is the manufacturer’s warranty on the turf against UV fading?
- How do you handle drainage in areas with heavy clay soil?
UK Regulations
- SUDS (Sustainable Drainage Systems): Installations should be permeable to prevent surface water runoff into the main sewer system.
- Waste Disposal: All excavated soil and old turf must be disposed of at a licensed facility. Ask for a waste transfer note if you are concerned.
- Planning Permission: Rarely required for back gardens, but front gardens may have restrictions regarding permeable surfaces if the area exceeds 5 square metres.
Common Problems
- Sinking or Dipping: Usually caused by an insufficient sub-base or poor compaction, leading to puddles.
- Visible Seams: If the "grain" of the two pieces isn't aligned or the gap is too wide, the join will look like a bright green scar.
- Weed Growth at Edges: Occurs when the weed membrane isn't properly secured to the edging perimeter.
- Odour Issues: Using the wrong infill or base material in gardens with dogs can lead to ammonia build-up.
Frequently Asked Questions
Is artificial grass safe for dogs and cats?
Yes, most modern turfs are non-toxic and very durable. For dog owners, it is vital to use a permeable "latex-free" or polyurethane backing and a zeolite infill to help neutralise odours.
How long does artificial turf last?
A professionally installed lawn should last between 12 and 15 years, depending on the level of foot traffic and how well it is maintained.
Does it get very hot in the summer?
Artificial grass can retain more heat than natural grass. On very hot days, it may feel warm to the touch, but a quick spray with a garden hose will cool it down instantly.
Does it require any maintenance at all?
While you don't need to mow it, you should leaf-blow or rake debris off the surface regularly. An occasional "power brush" by a professional can also help keep the fibres standing upright.
Can it be laid on top of existing concrete?
Yes, provided the concrete is in good condition and has a slight fall for drainage. A specialist underlay or "shock pad" is usually used to provide cushioning and aid water flow.
