This is hard to answer because every installation is unique.
You can find our artificial grass prices on this website, but remember these prices are for grass only and not installation.
Because installation costs vary widely.
As a rough guide, a 60 square meter lawn typically takes two installers two days to complete.
Then you have waste disposal costs, sub-base installation costs (aggregate availability and cost will vary across the UK), weeding membranes, edge restrictions and other installation accessories such as adhesives and joint tape.
Some installations also require more cutting than others, which may take longer.
Since artificial grass is only 2m and 4m wide, you may be wasting too much resources trying to achieve the size and shape of your lawn that you need.
Also, if the grass is on a deck or concrete/paving, the installation method is different and thus the costs involved.
Hope you understand by now, unfortunately there is no set price for artificial turf installation.
However, to give you a very rough idea, an average 60sqm lawn can cost £2,500-£3,500 including materials, labor and VAT.
The best way to get an idea of costs is to contact three reputable local artificial grass installers and ask each of them to provide you with a written quote.
