If you are planning a garden renovation, you might be surprised to learn that porcelain paving is now more affordable than ever. While it was once considered a luxury "premium-only" material, modern manufacturing and increased supply have brought the cost of porcelain paving slabs down to levels that directly compete with natural stone like Indian Sandstone.
On average, for a professional installation in the UK, you should budget between £100 and £150 per square metre for the entire project. Here is a realistic breakdown of the costs for 2026.
1. Breakdown of Costs per Square Metre
Because porcelain is calibrated (perfectly uniform in size and thickness), it can often be laid more efficiently than irregular natural stone. The total cost is typically split into three areas:
- The Slabs (£20 – £25 per m²): Budget-friendly, high-quality porcelain now starts as low as £20–£25 per square metre. While Italian designer ranges still exist at £50+, most homeowners find excellent options at the lower price point.
- Installation Materials (£15 – £25 per m²): This includes the sub-base (MOT Type 1), sharp sand, cement, and the essential SBR slurry primer used to bond the non-porous slabs to the mortar bed.
- Labour (£50 – £90 per m²): This covers excavation, base preparation, and laying. Because porcelain slabs are light and uniform, many contractors now charge the same daily rate for porcelain as they do for natural stone.
2. Total Project Price Guide
To give you a better idea of the "all-in" price for a completed patio, including waste removal (skips) and all materials:
- Small Patio (approx. 15m²): £1,500 – £2,300
- Medium Patio (approx. 30m²): £3,000 – £4,500
- Large Patio (approx. 50m²): £5,000 – £7,500
3. Why Porcelain Offers Excellent Value
When comparing porcelain to other materials, it’s important to look at the "total cost of ownership." Porcelain often ends up being the cheaper option over 5–10 years for several reasons:
- No Sealing Required: Unlike sandstone or limestone, which require specialist sealants every 2–3 years (costing £100+ per application), porcelain is vitrified and naturally non-porous.
- Uniform Installation: Because every slab is exactly 20mm thick, there is no need for the installer to manually "adjust" the depth of the mortar bed for every single stone, which can speed up the laying process.
- Longevity: Porcelain is frost-proof and fade-resistant. It won't lose its colour in the sun or crack during a hard UK winter, meaning you won't spend money on replacement slabs.
4. Important Considerations for Your Quote
While the material price is lower than it used to be, ensure your contractor includes these porcelain-specific requirements in their price:
- The Slurry Bond: This is a non-negotiable step. Because porcelain doesn't absorb water, it won't stick to cement alone. A primer (slurry) must be applied to the back of the slabs.
- Diamond Cutting: Professional porcelain installation requires diamond-tipped blades. A clean, factory-finish cut is what gives porcelain its high-end look.
- Drainage: Since porcelain doesn't absorb any water, your quote should include a slight "fall" (gradient) to ensure rainwater runs off into a flower bed or drainage channel.
