How much does artificial grass cost for a small garden? (UK guide)

The short answer

For a small UK garden, artificial grass is often quoted at the higher end of the supply-and-fit range — roughly £60 to £80 per square metre or more — because fixed costs spread over fewer metres. A compact lawn of around 15 m2 commonly costs in the region of £900 to £1,500 fitted, and a 25 m2 garden often falls between £1,200 and £2,000, depending on access, ground conditions and grass grade. Many installers also apply a minimum charge for small jobs, so very tiny areas can cost more per metre than the headline rate suggests. Doing the groundwork yourself on a small, flat, simple area can reduce the cost noticeably.

Small gardens have an awkward cost profile: the area is little, but the set-up costs are much the same as for a bigger job, so the price per metre rises. Knowing why helps you budget realistically.

Why small gardens cost more per square metre

It seems counterintuitive, but a small lawn often costs more per square metre than a large one. The reason is that many costs are fixed regardless of size:

Set-up and access: getting tools, stone and a skip to the garden takes the same effort whether the lawn is 10 m2 or 100 m2.
Waste disposal: skip or grab hire has a minimum cost even for a small volume of spoil.
Edging runs: a small garden can have a long perimeter relative to its area, and edging is priced by length.
Minimum charges: installers often set a floor price to make a small job worth attending, which inflates the effective per-metre rate.

Spread those fixed costs over only 15 or 20 square metres and the rate per metre climbs, which is why small lawns tend to sit at the top of the typical fitted range.

Garden size	Indicative fitted total	Notes
~10 m2	~£700–£1,200	Minimum charges weigh heavily; high per-m2 rate
~15 m2	~£900–£1,500	Still small enough for fixed costs to dominate
~25 m2	~£1,200–£2,000	Per-m2 rate starts to ease
~40 m2	~£1,800–£3,000	Better value per metre

Indicative fitted totals for guidance only. Actual prices depend on access, soil, drainage needs, shape and the grade of grass chosen.

What is included and what raises the price

A small-garden quote covers the same elements as any installation: excavation and disposal, a compacted stone sub-base, a weed membrane, edging, the grass, sand infill and labour. On a small job the things that push the price up tend to be:

Poor access: a courtyard or rear garden reached only through the house means every barrow of stone and spoil is carried by hand, adding labour.
Removing a hard surface: if you are replacing an old patio, decking or concrete, the demolition and disposal add cost.
Drainage: heavy clay or an enclosed area with nowhere for water to go may need extra base depth or a soakaway.
Detail and shape: borders, raised beds and curves mean more cutting and edging relative to the small area.
Premium grass: on a small lawn the grass is a smaller share of the total, so upgrading to a better grade adds relatively little to the overall cost — often a worthwhile choice.

Upgrade the grass on small jobs: because the groundwork dominates the cost of a small lawn, choosing a denser, more realistic grass adds only modestly to the total. It is often the most cost-effective point at which to spend a little more.

Ways to keep a small-garden cost down

If budget is tight, there are sensible ways to reduce the cost of a small artificial lawn without cutting corners on the parts that matter:

Do the groundwork yourself: on a small, flat, simple area, a confident DIYer can excavate, lay the membrane and build the sub-base, paying only for materials and the grass. The skill is getting the base level, compacted and free-draining.
Lay over a sound hard surface: if you already have flat, free-draining concrete or paving, grass can sometimes go over it with minimal preparation, avoiding excavation.
Combine with neighbours: if a neighbour wants the same work, a single visit can spread the fixed set-up and skip costs across two jobs.
Get the full scope quoted: make sure each quote covers the same base build-up and sand infill so you are comparing like for like rather than a thin spec against a proper one.

For a small garden, the realistic message is that the per-metre rate will be high but the total cost is modest in absolute terms, and the groundwork is where the money goes.

Common small-garden scenarios and what they cost

Small gardens come in a few recurring forms, and each has its own cost drivers worth recognising before you budget:

The enclosed back yard: a small rear garden reached only through the house is the classic awkward job. Every barrow of stone and spoil is carried by hand, so labour is high relative to the area. Drainage can also be a concern in an enclosed space with nowhere obvious for water to go, sometimes needing a soakaway.
The front garden: often more accessible than a rear yard, which keeps labour down, but frequently replacing an old lawn or worn paving, so the cost depends on what has to be removed first.
The courtyard over a hard surface: where there is already sound, flat, free-draining concrete or paving, grass can sometimes be laid over it with minimal preparation, cutting out the expensive excavation and sub-base and reducing the total considerably.
The shaped or planted plot: a small garden with curved borders, raised beds or a tree has a long perimeter and lots of cutting and edging relative to its area, which pushes up the labour and edging cost.

Recognising which scenario your garden fits helps you anticipate where the cost will land within the typical small-garden range. The two factors that move it most are access — how easily materials and waste can be moved — and what lies beneath, since laying over a sound hard surface is far cheaper than full excavation through difficult access. Knowing these in advance means a quote is less likely to surprise you, and lets you weigh whether doing the excavation yourself, or laying over an existing surface, could bring the figure down.

Access and base decide the price: for a small garden, how easily materials reach the plot and what lies beneath matter more than the area itself. An accessible courtyard over sound concrete can cost far less than a tiny enclosed yard needing full excavation by hand.

Frequently asked questions

Why does my small garden cost almost as much per metre as the grass itself?

Fixed costs — access, set-up, skip hire and minimum charges — make up a large share of a small job and do not shrink with the area. Spread over only a few square metres, they push the effective rate per metre well above what a larger lawn would pay.

Is it worth getting artificial grass for a tiny courtyard?

It can be, especially where a real lawn would struggle for light or drainage. The total cost is modest in absolute terms, and because groundwork dominates a small job, spending a little more on a better grade of grass adds relatively little while improving the look and lifespan.

Can I save money by laying a small lawn myself?

Yes, on a small, flat, simple area DIY can save the labour cost, which is often the biggest line. You still pay for the grass, sub-base materials, membrane, edging, infill and a skip. The challenge is building a level, well-compacted, free-draining base — get that wrong and the lawn can dip or hold water.
