Patio Cost Guide: What You'll Pay by Material and Size

A concrete slab patio typically costs £40-£70 per square metre installed, porcelain paving usually runs £70-£110 per square metre, and natural stone (such as Indian sandstone or limestone) typically costs £70-£120+ per square metre depending on the specific stone chosen. For a typical UK patio of around 20-30 square metres, this translates to a total project cost roughly from £1,000 at the budget end to £3,500+ for a premium natural stone finish, before any additional features like steps, retaining edges, or lighting.

Patio materials compared

• Concrete paving slabs: the most budget-friendly option, widely available, durable, and low-maintenance, though with the least premium appearance and a more limited colour/texture range than natural stone or porcelain.
• Porcelain paving: increasingly popular for its consistent appearance, low porosity (resists staining better than natural stone), and low maintenance — doesn't need sealing the way some natural stone does. Costs more than concrete but offers a more contemporary, uniform look.
• Natural stone (Indian sandstone, limestone, granite, etc.): the premium option, prized for its natural variation and character. Costs vary considerably by stone type — Indian sandstone tends to be more affordable than British stone like York stone, which can be significantly more expensive. Most natural stone benefits from periodic sealing to resist staining and algae growth.
• Block paving as a patio surface: less common for patios than driveways, but an option, typically similar cost to porcelain, and offering a good range of colours and patterns.

What affects the total cost beyond material

Groundwork is a major factor — a patio needs proper excavation, a compacted sub-base, and either a mortar bed or a sand/gravel bedding layer depending on the paving type, and skipping proper preparation is the most common cause of patios that crack, sink, or develop puddles within a few years. Site access affects labour cost in the same way as other garden work — materials that need to be carried through the house or over difficult ground cost more to install than a garden a machine can access directly. Pattern complexity (a simple grid layout versus a more intricate pattern or curved edges) and additional features like steps, edging, or drainage channels also add to the total.

DIY or professional?

A small, simple patio on flat, accessible ground with concrete slabs is a realistic DIY project for a competent, patient DIYer, though getting the sub-base and levels right (patios should have a slight fall away from the house, typically around 1:80, for drainage) takes care and is easy to get wrong. Larger patios, natural stone (which is often heavier and less forgiving of small errors in bedding), sloped sites, or anywhere near the house requiring damp-proof course clearance are generally better left to a professional.

Common mistakes

• Laying a patio without a fall for drainage. A completely flat patio can pool water, which looks unattractive and can eventually cause problems with frost damage or moss growth.
• Building the patio too close to the damp-proof course. UK building guidance typically requires paving to sit at least 150mm below the damp-proof course of the house to avoid bridging it and causing damp problems indoors.
• Underestimating the sub-base needed. A patio's sub-base depth needs to suit the ground conditions and expected use (a patio taking furniture and foot traffic needs less than a driveway, but still needs proper preparation) — skipping or skimping on this is the leading cause of premature failure.

Pattern and edging options

Beyond material choice, layout pattern affects both cost and appearance — a simple stretcher-bond or grid pattern is the most economical to lay, while herringbone, basketweave or a mix of paving sizes (a "random" or "project pack" layout, common with natural stone) takes longer to lay and typically costs more in labour, even using the same material. Edging — whether a contrasting border, a raised lip, or simply a neat cut edge against lawn or borders — is worth planning at the design stage, since retrofitting a proper edge restraint after the main paving is down is more difficult and can compromise the finished look.

Combining a patio with drainage and lighting

It's increasingly common to integrate a linear drainage channel along one edge of a patio, particularly where it meets the house, to manage surface water properly rather than relying on the paving's fall alone — this is a modest additional cost during installation but far more expensive to add afterwards. Similarly, if you want outdoor lighting or power sockets in the patio area (for a pizza oven, lighting, or an outdoor kitchen), running the cabling before the paving goes down avoids the disruption and cost of lifting slabs later.
