Patio Cost Per m² in Somerset, Devon & Dorset

If you’re planning a new patio, one of the most common questions is straightforward: what does it cost per square metre?

Across the UK in 2026, a professionally installed patio typically ranges between £90 and £200 per m², depending on material choice, ground conditions, access and specification.

That range is broad — but the reasons behind it are practical rather than arbitrary. A patio is not simply the surface you see. Much of the cost lies beneath it.

This guide explains where those costs come from and how to plan realistically.

Typical Patio Installation Costs Per m²

We know you’re probably looking at this article for a quick answer, but there are so many variables, all we can suggest are broad outlines. If you would like to read down further, you may hopefully gain an insight into why an exact number is often avoided, when a contractor is asked to give a guide price over the phone.

As a general framework:

Concrete paving slabs: £90–£120 per m²
Natural sandstone: £100–£160 per m²
Porcelain paving: £140–£200 per m²

These figures include labour and materials for a standard ground-level installation with reasonable access and no unusual ground complications. They also reflect the large range in price of some individual material choices. Porcelain paving slabs alone, can cost anything from £25 – £75 m2, just to buy the paving alone.

They do not include:

• Extensive excavation due to poor ground
• Retaining walls or steps
• Drainage systems beyond standard fall correction
• Complex patterns or detailing

For projects involving level changes or structural elements, costs increase accordingly.

What Makes Up the Cost of a Patio?

Understanding cost allocation helps avoid unrealistic budgeting.

Excavation and Ground Preparation

Before any paving is laid, the area must be excavated to sufficient depth. In most cases, this involves:

• Removing existing turf or surface
• Excavating to accommodate sub-base and bedding layers
• Disposing of spoil

Waste removal alone can represent a meaningful portion of total cost, particularly where access is restricted.

The required excavation depth depends on ground stability and intended load. Domestic patios typically require a compacted sub-base of 100–150mm, sometimes more on softer ground.

Sub-Base Installation

The sub-base provides structural integrity. This is not an area to economise.

Insufficient depth or poor compaction leads to movement, settlement and eventual failure. Proper installation involves layered compaction and accurate level control.

While unseen once complete, this stage determines longevity.

Bedding Layer and Laying

Traditional installations use a full mortar bed to support each slab. Porcelain typically requires additional priming slurry to ensure adhesion.

Labour time varies depending on:

• Slab size
• Joint width
• Pattern complexity
• Cutting requirements

Larger-format porcelain, for example, may reduce joint lines but increase handling time due to weight and precision requirements.

Materials

Material cost varies significantly.

Concrete slabs remain the most economical option. Natural sandstone sits mid-range. Porcelain generally commands a higher supply price, particularly for thicker, exterior-grade products.

However, installation complexity can sometimes outweigh supply cost differences.

Jointing and Finishing

Jointing compounds, pointing mortar and edge restraints complete the installation.

Edge detailing is often overlooked during budgeting. A patio without defined edges risks long-term movement.

Why Patio Prices Vary So Much

Two patios of identical size can generate very different quotations.

Access is often the primary factor. If machinery can reach the work area easily, excavation and material movement are faster. Where materials must be transported manually through a property, labour hours increase.

Ground conditions also influence cost. Clay-heavy soils may require deeper excavation. Previously filled ground can demand stabilisation.

Level changes introduce further complexity. If the patio must integrate with thresholds, steps or retaining structures, detailing time increases.

In most cases, price variation reflects labour and site constraints rather than material alone.

Working With Levels Rather Than Against Them

One of the most effective ways to manage patio cost is to work with the natural fall of the site.

Attempting to create perfectly level terraces in sloping gardens can require substantial excavation and retaining work. In some cases, allowing subtle transitions reduces both structural demand and overall expenditure.

This is where experienced design input can influence budget positively. Adjusting orientation, reducing unnecessary cut lines or simplifying edge detailing can produce meaningful savings without compromising quality.

Can You Reduce Patio Costs Without Compromising Quality?

Often, yes.

Cost efficiency typically comes from thoughtful decisions rather than material downgrading.

Examples include:

• Selecting slab dimensions that reduce cutting
• Simplifying laying patterns
• Choosing durable mid-range materials over premium imports
• Retaining sound existing sub-base where viable
• Phasing additional features such as walls or integrated seating

Well-considered planning ensures the budget is allocated where it matters structurally rather than cosmetically.

Additional Costs to Consider

When budgeting for a patio, allow for:

• Removal of existing concrete or paving
• Skip hire or grab lorry charges
• Drainage channels if required
• Steps or retaining edges
• Lighting integration

A realistic contingency of 5–10% is sensible where ground conditions are uncertain.

Is a Patio Worth the Investment?

In most residential gardens, a patio forms the primary usable surface. It defines circulation, seating areas and access between house and garden. So many of us treat the garden as an outdoor room these days, rather than the more utility area it used to be years ago.

When installed correctly, it should last decades with minimal maintenance.

The difference between a patio that remains stable and one that shifts within a few winters is almost always found beneath the surface — in preparation and detailing rather than appearance.

A professionally installed patio is not simply paving; it is groundwork, structure and level control working together.

Final Thoughts

In 2026, a realistic budget for a professionally installed patio in the UK sits between £90 and £200 per m², depending on material and site conditions.

The variation reflects preparation depth, access constraints and detailing — not just the slab you choose.

If you are planning a wider garden redesign, integrating patio design within a structured layout phase often results in better cost control and improved proportions overall.

Clear design, accurate specification and build-aware thinking tend to produce more predictable outcomes than surface decisions alone.
