Grass quality
Budget artificial grass costs less, but premium grass usually looks fuller and feels softer. Pet-friendly grass can also cost more because drainage and hygiene matter.
Artificial grass cost calculator
Artificial Grass Cost Calculator UK
Estimate artificial grass installation cost using lawn area, grass quality, base preparation, sub-base type, access and region. This calculator focuses on the full installed system, not just the price of fake grass per roll.
Why artificial grass costs vary
Artificial grass cost is not just the grass. The fitted price depends on the surface underneath, how much ground needs removing and whether the base can drain properly.
Base preparation
Removing old turf, excavating soil, adding a compacted sub-base and fitting a laying course can cost more than the grass itself on difficult sites.
Drainage
Artificial grass still needs water to move away. Clay soil, poor falls and low spots can require extra base work before the surface is laid.
Compare artificial grass types
The best option depends on how visible the lawn is, whether pets use it and how realistic you want the finished surface to look.
| Artificial grass type | Typical cost behaviour | Best suited to |
|---|---|---|
| Budget artificial grass | Lower upfront | Low-use areas, rental gardens and simple patches |
| Mid-range realistic grass | Typical | Most domestic gardens and general lawn replacement |
| Premium dense grass | Higher range | Front gardens, family spaces and appearance-led projects |
| Pet-friendly grass | Mid to high range | Dog areas, shaded gardens and surfaces needing better drainage |
| Not sure | Wider estimate range | Early planning before comparing samples |
If you want a natural lawn instead, use the Turf Installation Cost Calculator.
Typical UK artificial grass cost ranges
These are broad planning figures. Use the calculator above for a more specific estimate based on grass type, area, base preparation, sub-base and region.
| Artificial grass project | Typical range | Cost pattern |
|---|---|---|
| Small artificial grass patch | £700–£1,500+ | Minimum labour, waste removal and delivery still matter |
| Standard garden installation | £1,800–£4,500+ | Area, grass quality and base preparation drive cost |
| Premium artificial lawn | £3,000–£7,000+ | Denser grass, better finish and more detailed cutting raise cost |
| Pet-friendly artificial grass | £2,500–£6,500+ | Drainage, odour control and cleaning requirements can add cost |
| Poor drainage or clay ground | £3,500–£8,000+ | Excavation, sub-base depth and drainage work can dominate |
What affects artificial grass installation cost?
The final quote depends on the grass you choose and the construction work needed below the surface.
Lawn area
Larger areas need more artificial grass, more joining and more base preparation. Small jobs can still have a higher cost per m² because setup costs remain.
Excavation
Existing turf, weeds, soil or rubble may need removing before the base can be built. This adds labour, skip cost and disposal time.
Sub-base depth
A good artificial lawn usually needs a stable compacted base. Weak or shallow preparation can lead to dips, movement and poor drainage.
Drainage
Clay soil and low spots can hold water beneath the surface. Extra drainage work may be needed before the grass is installed.
Edges and fixing
Artificial grass needs secure edges. Timber, concrete, metal edging or fixing rails may be needed where the lawn meets patios, paths or fences.
Joins and shape
Curves, steps, trees and awkward garden shapes increase cutting and joining time. More joins can also increase waste allowance.
The hidden cost: base preparation and drainage
Artificial grass is a surface layer. The part that decides how well it performs is usually underneath: excavation, weed membrane, compacted sub-base, laying course, edging and drainage.
If the garden holds water after rain, check the Garden Drainage Cost Calculator before committing to a fake grass installation.
If you are mainly comparing upfront cost, use the Turf Installation Cost Calculator beside this page.
Already have an artificial grass quote?
Check whether the quote includes excavation, waste removal, weed membrane, MOT Type 1 or suitable aggregate, laying course, edging, joining tape, adhesive, sand infill if required, delivery and VAT.
A low quote may only cover the visible grass and basic fitting. If artificial grass is part of a wider garden project, check it within your full garden landscaping budget.
Artificial grass or natural turf?
Artificial grass is usually more expensive to install than natural turf because the base has to be built like a small landscaping surface. It can suit shaded areas, high-use spaces and homeowners who want less mowing.
Natural turf is usually cheaper upfront and gives a living lawn, but it needs mowing, watering and care. Compare both options with the Turf Installation Cost Calculator.
Planning artificial grass with the rest of the garden?
Artificial grass often sits beside a patio, deck, path or fence. If you are planning the full layout, compare this estimate with the Patio Cost Calculator, Decking Cost Calculator and Fencing Cost Calculator.
If levels are changing or the lawn sits beside a raised area, you may also need the Retaining Wall Cost Calculator.
How this artificial grass estimate is calculated
The calculator starts with an installed artificial grass cost per m² for the selected grass type. It then adjusts the estimate using base preparation, sub-base type, access and region.
An 8% grass waste allowance is used for cuts, joins and trimming. A 10% planning allowance is added to the cost estimate for quote variation, small material differences and site-specific adjustments.

Artificial grass cost FAQs
How much does artificial grass cost in the UK?
A small artificial grass area may cost under one thousand pounds, while larger gardens with premium grass, excavation, sub-base and drainage work can cost several thousand pounds.
What is the average artificial grass cost per m²?
Cost per m² depends on grass quality, excavation, sub-base depth, drainage, edging, access and region.
Why is artificial grass more expensive than turf?
Artificial grass usually needs excavation, a compacted sub-base, a laying course, weed membrane and secure edges. Turf is usually cheaper to lay upfront.
Does artificial grass need drainage?
Yes. Water still needs to move through or away from the surface. Poor drainage can lead to pooling, smells and base problems.
Can artificial grass be laid over soil?
Usually not directly. Soil normally needs excavating and replacing with a compacted base and laying course.
Is pet-friendly artificial grass more expensive?
It can be. Pet-friendly installs may need better drainage, suitable backing, odour control and easier cleaning.
How much artificial grass do I need?
This calculator adds an 8% waste allowance to the selected area. Complex shapes, curves and joins may need more.
Are CostIntel artificial grass estimates fixed quotes?
No. They are planning estimates based on typical UK artificial grass cost drivers. A landscaper needs to inspect the area before giving a fixed quote.
