Who this guide is for
- Homeowners considering replacing a lawn with artificial grass
- People budgeting an outdoor project and comparing quotes
- Anyone weighing artificial against natural grass
- Readers preparing to brief an installer
Base preparation and ground conditions
The biggest hidden driver is usually what lies beneath. Removing existing turf, excavating, and building a stable, free-draining base takes effort that varies with soil type and condition.
Poor drainage or unstable ground can add significant preparation work, which is why site assessment matters.
Two gardens of the same size can differ widely once the ground beneath is accounted for, which is why a site visit and itemised groundwork line in a quote tell you far more than a headline rate.
- Existing surface removal and disposal
- Excavation depth and soil conditions
- Sub-base build-up and compaction
- Drainage provisions
Grade, levels and shape
Sloped or uneven ground, tight curves and complex shapes all increase the work involved in achieving a smooth, well-finished result.
Simple rectangular areas are generally more straightforward than fragmented or contoured layouts.
Curves, slopes and fragmented shapes all add labour that a simple rectangle avoids, so describing the true shape of the area, not just its overall size, helps a quote reflect the work involved.
Product specification and infill
Turf products differ in pile, backing and durability, and infill choices affect both feel and longevity. Edging and joining details also influence the work involved.
Specification choices interact with intended use, such as play or pets.
Access and site logistics
How easily materials and waste can move to and from the area affects labour. Restricted rear-garden access can mean more handling.
Waste disposal and protection of surrounding surfaces also factor in.
Artificial grass budget-planning checklist
- 1Note the existing surface and its condition
- 2Assess slope, levels and shape of the area
- 3Consider drainage and ground conditions
- 4List intended uses such as pets or play
- 5Think about access for materials and waste
- 6Compare specification options on like-for-like terms
- 7Ask quotes to itemise base preparation separately
- 8Factor in protection and cleanup
Common mistakes to avoid
- Comparing quotes only on turf type while ignoring base preparation
- Underestimating drainage needs on heavy or compacted soil
- Forgetting waste disposal and access constraints
- Assuming a sloped area costs the same as a flat one
- Overlooking edging and joining details
When to involve a professional
- Drainage and ground conditions should be assessed by qualified professionals
- Costs vary widely by site, access and specification
- Quotes differ in what they include, so compare scope carefully
- No single figure applies across projects or regions
Frequently asked questions
Questions readers ask about this topic
What usually drives artificial grass cost the most?
Base preparation often has the biggest influence, because excavation, sub-base and drainage vary with the site. The turf product matters too, but groundwork is frequently the larger variable.
Does this guide give a price per square metre?
No. It only explains the factors that affect cost. For figures specific to your project, gather itemised quotes from professionals, since prices vary by site and specification.
Why do quotes differ so much?
Quotes vary because they may assume different base build-ups, drainage, products and access. Comparing them on a like-for-like scope makes differences easier to understand.
Is artificial grass always cheaper than maintaining a lawn?
It depends on many factors over time, and this guide does not make that claim. Weigh upfront work against ongoing maintenance for your situation, ideally with professional input.
