Replacing a real lawn with artificial grass is one of the bigger garden decisions you’ll make, and the install itself is what determines whether you end up with ten years of a low-maintenance, mud-free garden or a wavy, weed-strewn surface that needs lifting after the first winter.

This is a complete UK homeowner’s guide to fitting artificial grass what tools and materials you’ll need, the full step-by-step process, typical costs, and how to look after the lawn once it’s down. We’ve been fitting artificial lawns across the UK since 2011, so the advice here is the version our own installers actually follow on site, not generic content rewritten from abroad.

Before You Start: A Quick Word on Planning

A bit of planning saves a surprising amount of grief later. The single most useful thing you can do before ordering anything is feel the grass in person  the colour and pile of a sample looks noticeably different in real daylight than it does on a website. You can order a free sample pack and we’ll send you a selection of pile heights and styles to compare side by side in your own garden before committing to a roll.

Once you’ve chosen your grass, check the British weather forecast. Heavy rain stops play during installation because wet aggregate can’t be compacted properly, and the sand infill at the end needs a dry day to spread evenly. A run of two to three consecutive dry days is what you want.

Tools and Materials You’ll Need

Tools

• Spade and turf cutter (the turf cutter is hireable from any UK tool hire shop)
• Wheelbarrow
• Wacker plate a vibrating compactor, hire one for the day
• Sharp Stanley knife with plenty of spare blades
• Hammer
• Tape measure, string line, and a spirit level
• Stiff outdoor broom, or a power brush for larger gardens
• Knee pads and gardening gloves

Materials

• Artificial grass, ordered from a single production batch
• MOT Type 1 hardcore for the sub-base
• Sharp sand or grano dust for the binding layer
• Two rolls of permeable weed membrane
• Treated timber, steel, or composite edging
• 150mm galvanised steel nails or U-pins
• Joining tape and outdoor-grade adhesive (only if seaming rolls together)
• Kiln-dried silica sand for the infill

The 10-Step Process for Installing Artificial Grass

Step 1: Measure and Order Your Grass

Measure your garden at the widest and longest points, then add 5–10% for trimming. Roll widths in the UK come in 2m, 4m, and 5m picking the right one can mean the difference between a seamless lawn and one with an unnecessary join. Always order all your grass from a single batch, as colours can vary very slightly between production runs.

Step 2: Excavate the Existing Lawn

Mark out the area with string and pegs, then strip back everything currently there old turf, weeds, paving sand, decorative bark to a depth of around 75 to 100mm. A turf cutter slices through real grass in minutes. Before going deep, give a thought to cables and pipes feeding sheds, taps, or garden lights. If in doubt, dig that section by hand.

Step 3: Install the Edging

The edging holds your sub-base in place and gives you something to nail the grass into later. If your lawn already runs into patio, decking, or a wall on every side, skip this step. Otherwise, knock treated timber battens into the soil so the top sits flush with the planned grass level.

Step 4: Lay Two Layers of Weed Membrane

Most installers use one layer of weed membrane. We always use two, laid at right angles to each other. A single layer stops most weeds, but bindweed and horsetail will eventually push through. Two layers crossed at 90 degrees means any gap in the first is covered by the second. Pin both layers down around the perimeter every 500–750mm.

Step 5: Build the Sub-Base

This is the step that matters more than any other. Tip MOT Type 1 hardcore into the cleared area to a depth of 50–75mm. Spread it out, wet it lightly with a hose, then run the wacker plate over it in overlapping passes. The test for proper compaction is simple if your boot leaves a print, it isn’t done.

Step 6: Add the Binding Layer

On top of the hardcore, lay a 25mm binding layer of sharp sand or grano dust. Drag a straight length of timber across the surface in a slow sawing motion to screed it flat, building in a very gentle fall away from the house (about 1cm per metre) so rainwater drains rather than pools. One final pass with the wacker plate and the base is ready.

Step 7: Roll Out and Acclimatise the Grass

Unwrap the grass, roll it out across the prepared base, then leave it for an hour or two in the sun. The fibres have been crushed flat in the roll for weeks and need time to relax  trim too soon and you’ll fight creases all day. While it settles, sort out pile direction. The blades lean slightly in one direction, and the lawn looks lushest when you’re looking into the pile. Point it towards your main viewing point  usually the kitchen window.

Step 8: Trim and Join Any Seams

Trim the manufacturer’s strip off both long edges with a fresh Stanley knife blade. If your garden is wider than your roll, you’ll need a seam. Three rules: both rolls must run the same way, cut the seam in a gentle S-shape rather than a straight line, and use proper joining tape with outdoor adhesive. Press both edges down onto the tape and weight with planks for at least 24 hours while it cures.

Step 9: Secure the Edges

Use 150mm galvanised steel nails every 100–150mm around the perimeter. Drive each one three-quarters of the way in, part the blades around the head with your fingers, then tap the rest of the way home. The grass closes back over the nail and hides it completely. Don’t drive nails too deep  past the level of the backing mat, you’ll pull the grass down and create dimples around the edge that can’t easily be fixed.

Step 10: Brush and Apply the Sand Infill

Brush the lawn vigorously against the grain to lift the blades upright. Then scatter kiln-dried silica sand evenly at 5–8kg per square metre closer to 5kg for short pile, closer to 8kg for longer pile. Brush it in thoroughly so it drops between the blades to the base of the pile. The sand weighs the grass down and holds the fibres upright. Do this on a dry day  wet sand clumps. One final brush against the grain and you’re done.

How Much Does Installation Cost in the UK?

Costs vary by region, garden size, and the quality of grass you choose. As a rough guide, most UK supply-and-fit jobs work out at £45–£60 per square metre for budget grass, £60–£80 per square metre for mid-range, and £80–£120 per square metre for premium products. These figures cover both materials and labour. The grass itself is usually the smaller part of the bill  most of the cost is the groundwork, which is why cheap installations often skimp on the sub-base depth or weed membrane. Both corners show up later as ripples and weed growth.

DIY can roughly halve the cost, but allow for tool hire (£40–£60 a day for a wacker plate and turf cutter), skip hire if you’ve a lot of soil to dispose of (£200 and up), and a weekend’s hard physical work.

When to Hire a Professional

DIY tends to work well for small, simple gardens under about 40 square metres with straight edges and reasonably flat ground. A professional install starts to make more sense for larger lawns, anything with significant curves or slopes, gardens needing three or more rolls with multiple seams, or sites where drainage is already a problem. If your garden falls into the trickier camp, you can request a free installation quote and one of our team will come out to measure and price the job there’s no obligation either way.

Aftercare: Looking After Your New Lawn

Your new lawn is ready to walk on as soon as the sand has been brushed in, but allow 24–48 hours before moving heavy garden furniture so any seams have time to cure properly. After that, maintenance is genuinely minimal. Brush the high-traffic areas every few weeks with a stiff broom to keep the blades upright, rake off fallen leaves in autumn before they break down, and hose the lawn down occasionally if you’ve dogs or pets. Top up the sand infill every few years if the pile starts to look flat.

A well-fitted artificial lawn gives you ten years or more of a green, mud-free garden, and saves you a small fortune in mowing, watering, and weeding over that time.
