Frequently Asked Questions
How much does artificial grass cost per m²?
Supply only costs range from £10/m² for budget grass to £60/m² for luxury. Fully installed (including sub-base, membrane, edging, and labour), expect to pay £40-£120/m². The average UK installation of 40m² costs £2,500-£4,500 for mid-range grass with professional fitting.
How long does artificial grass last?
Quality artificial grass lasts 15-20 years with proper maintenance. Budget options may last 8-12 years. UV-stabilised grass resists fading. Factors affecting longevity include: quality of sub-base, drainage, foot traffic, pets, and maintenance routine. Most manufacturers offer 7-10 year warranties.
Does artificial grass need a sub-base?
Yes, for best results. A proper sub-base (typically 50-75mm of compacted MOT Type 1 aggregate) provides drainage, prevents sinking, and ensures a level surface. Laying artificial grass directly on soil leads to poor drainage, unevenness, and premature deterioration. Budget £8-£18/m² for sub-base preparation.
Is artificial grass pet-friendly?
Yes. Most modern artificial grass is designed to be pet-friendly with drainage holes and antimicrobial treatments. Dog urine drains through into the sub-base. Solid waste should be picked up and the area rinsed. Some owners apply specialist infill sand to neutralise odours. Avoid grass with lead content.
Does artificial grass affect house value?
Artificial grass is generally neutral to slightly positive for house value. Well-installed, high-quality grass can enhance kerb appeal and attract buyers who value low maintenance. However, some buyers prefer real grass, especially in premium properties. For rental properties, artificial grass reduces maintenance obligations.
Can I install artificial grass myself?
DIY installation is possible and saves £20-£30/m² on labour. You will need to: excavate 75-100mm, lay weed membrane, add and compact sub-base, lay the grass with overlaps joined by adhesive and joining tape, secure edges, and brush in kiln-dried sand. Typical DIY time: 2-3 days for 40m². Mistakes with joins are common.
