Artificial grass installation in the UK can cost from around £45 to more than £90 per square metre, depending on the turf, garden condition, access, drainage, and finish required. For many domestic projects, a realistic working budget is between £55 and £85 per square metre for supply and professional fitting.
That means a 20m² garden may cost approximately £1,100 to £1,700, while a 40m² lawn could cost around £2,200 to £3,400. These figures are only a guide because two gardens with the same measurements can require very different preparation.
The grass itself is only one part of the price. Excavation, waste removal, sub-base materials, edging, joining products, labour, and drainage can all influence the final quotation. Understanding these cost areas makes it easier to compare installers and avoid quotes that leave out essential groundwork.
Average Artificial Grass Installation Cost Per m²
Typical UK supply-and-fit price ranges are:
| Installation level | Typical cost per m² | Common use |
| Basic installation | £45 to £55 | Simple gardens with limited preparation |
| Standard installation | £55 to £75 | Family gardens needing normal groundwork |
| Premium installation | £75 to £90+ | Better turf, difficult access, drainage, or detailed edging |
A lower headline price is not always better value. If excavation, waste disposal, drainage, or edge restraints are missing, extra charges may appear later.

Artificial Grass Cost by Garden Size
The following estimates use a broad installed rate of £55 to £85 per square metre.
| Garden size | Estimated installation cost |
| 10m² | £550 to £850 |
| 20m² | £1,100 to £1,700 |
| 30m² | £1,650 to £2,550 |
| 40m² | £2,200 to £3,400 |
| 60m² | £3,300 to £5,100 |
| 100m² | £5,500 to £8,500 |
Larger projects cost more overall, although the rate per square metre may sometimes reduce because delivery and setup costs are spread across a wider area.
Small gardens can have a higher unit cost when access is restricted or detailed cutting is required around steps, borders, drains, and other features.
What Is Included in Artificial Grass Installation?
A complete installation over soil normally involves removing the old lawn, shaping the area, adding a permeable membrane, installing and compacting a sub-base, laying a finer finishing layer, fixing edging, fitting the turf, joining sections, and brushing the fibres.
A professional quote may include:
- Artificial grass supply
- Existing turf and soil removal
- Skip hire or waste collection
- Weed membrane
- MOT Type 1 or another suitable sub-base
- Granite dust or a similar levelling layer
- Edging materials
- Joining tape, adhesive, pins, or fixings
- Labour and equipment
- Drainage improvements
- Final brushing and site clearance
Ask whether VAT, delivery, waste removal, and all base materials are included. A quote that only covers the turf and fitting may not represent the true artificial grass installation cost.
How Turf Quality Changes the Price
Supply-only artificial grass commonly starts at approximately £10 to £15 per square metre for entry-level products. Mid-range domestic turf may cost around £15 to £25, while premium products can reach £25 to £45 or more.
More expensive grass may have denser stitching, stronger backing, improved fibre recovery, a more natural colour blend, or specialist features for pets and heavy use.
Pile height can influence the price, but taller grass is not automatically better. A busy family lawn may perform better with durable medium-pile turf than a long decorative product.
The right choice should reflect:
- Expected foot traffic
- Children and pets
- Garden furniture
- Cleaning requirements
- Fibre recovery
- Drainage performance
- Maintenance expectations
Ordering samples before installation can help you compare colour, softness, density, and recovery in natural daylight.
Groundwork Is a Major Part of the Budget
Ground preparation is often the biggest difference between a cheap quotation and a properly planned artificial grass installation.
An uneven, overgrown, or waterlogged garden takes longer to excavate and may require more aggregate. Tree roots, old paving, concrete, buried rubble, and poor soil can also increase labour and disposal costs.
A stable base supports the turf and helps prevent:
- Sinking
- Rippling
- Uneven areas
- Loose edges
- Standing water
- Visible depressions
Reducing the depth or quality of the sub-base to lower the price may create costly problems later.
Gardens with firm ground and simple levels are usually cheaper to prepare. Clay soil, waterlogging, or major height changes may require more extensive work.
Drainage Can Increase Installation Costs
Artificial grass backing allows water to pass through, but the ground beneath must also manage it. If rain already collects in the garden, the problem should be addressed before installation.
Standard drainage may be created through a permeable sub-base and gentle slope. More difficult sites may require:
- A French drain
- A channel drain
- A soakaway
- A land drain
- Deeper excavation
- Additional permeable aggregate
These additions increase the initial artificial grass fitting cost, but ignoring drainage may lead to standing water, smells, moss, or movement beneath the lawn.
Pet-friendly gardens may also need faster drainage, specialist backing, or odour-control infill. The installer should explain how rainwater, cleaning water, and pet urine will move away from the surface.
How Garden Access Affects the Price
Easy garden access can reduce labour time. A wide side gate allows machinery, aggregate, turf rolls, and waste to move efficiently.
Costs may rise when workers must:
- Carry materials through the house
- Use a narrow alley
- Climb several steps
- Move waste over a long distance
- Work around limited parking
- Use smaller equipment because machinery cannot enter
Restricted access can turn a straightforward installation into a labour-intensive project.
Excavation also produces a significant amount of waste. The quotation may include a skip, grab hire, or repeated waste collections. Confirm how disposal will be managed and whether a road permit is required.
Edging, Garden Shape, and Turf Joins
A rectangular lawn is usually easier and cheaper to install than a garden with curves, narrow sections, tree surrounds, steps, or several levels.
Complex shapes require more measuring, cutting, and fixing. They can also create more waste because artificial grass is supplied in standard roll widths.
Wide gardens may require several pieces of turf to be joined. Good seams need suitable joining tape, adhesive, and careful workmanship. A weak or visible join can affect both appearance and durability.
Secure edging prevents the perimeter from lifting and keeps the base materials in position. Timber, composite, metal, and concrete edging options can all affect the total artificial grass installation cost.
DIY vs Professional Artificial Grass Installation
Buying artificial grass supply-only and completing the work yourself can reduce labour costs. However, base materials, waste disposal, equipment hire, edging, and joining products are still required.
DIY installation may suit a small and simple area if you can excavate, compact, level, cut, and join the turf accurately.
Professional fitting is generally more suitable for:
- Large gardens
- Restricted access
- Drainage problems
- Sloping ground
- Clay soil
- Multiple turf joins
- Complex edging
- Children’s play areas
Poor groundwork can lead to sinking or waterlogging, while incorrect joining may leave visible lines or loose sections.
The potential cost of correcting mistakes should be considered when comparing DIY work with professional installation.
Hidden Artificial Grass Installation Costs
Before accepting a quotation, check whether it includes:
- Delivery of turf and aggregates
- Removal of existing grass and soil
- Skip hire and permits
- Additional drainage work
- Edging around the full perimeter
- Steps or level adjustments
- Shock pads for play areas
- Pet-friendly infill
- Removal of old paving or concrete
- Tree-root removal
- VAT
- Product warranties
- Workmanship guarantees
It is also useful to ask what could change the price after excavation begins. Unexpected rubble, unstable soil, drainage pipes, and deeper-than-expected roots can increase the amount of work required.
Is Artificial Grass Worth the Installation Cost?
Artificial grass has a higher upfront cost than reseeding a lawn or laying basic natural turf. Its value comes from reducing mowing, watering, feeding, weed control, and repeated lawn repairs.
For example, a professionally installed lawn costing £3,000 and lasting 15 years works out at approximately £200 per year before routine cleaning.
The real value depends on what you currently spend on natural lawn care and whether real grass performs well in your garden.
Artificial grass can be especially practical in:
- Shaded gardens
- Muddy family gardens
- Pet areas
- Rental properties
- High-traffic spaces
- Gardens where mowing is difficult
It may be less suitable for homeowners who prioritise natural planting, wildlife habitat, or the lowest possible upfront cost.
How to Get an Accurate Artificial Grass Quote
Measure the lawn’s maximum length and width to create an initial estimate, but request a site survey before making a final decision.
The installer should assess:
- Garden levels
- Existing soil
- Access
- Drainage
- Edging
- Roll direction
- Number of joins
- Waste removal
- Intended lawn use
Ask for an itemised written quote that identifies the artificial grass product and every stage of the installation.

Comparing several detailed quotations is more useful than choosing the lowest total. Check previous installations, warranties, insurance, and experience with similar gardens.
Final Thoughts
So, how much does artificial grass installation cost in the UK? Many professionally fitted domestic lawns fall between £55 and £85 per square metre, although simple projects may cost less and complex work can exceed £90 per square metre.
The final total depends on more than garden size. Turf quality, excavation, sub-base depth, access, drainage, edging, joins, and waste removal all influence the price.
A clear, itemised quotation helps prevent essential groundwork from being overlooked. Investing in the correct base and drainage may increase the upfront budget, but it also gives the artificial lawn a better chance of staying level, secure, and usable for many years.
