Lay a porcelain patio.

Porcelain has overtaken sandstone as the UK's most-installed new patio material — and for once, the hype is justified. It's effectively non-porous, frost-proof, stain-proof, and looks like whatever stone, wood, or concrete you want it to. This guide covers what a finished porcelain patio costs in 2026, the install detail that catches DIYers out, and the finishes that work in real UK gardens.

The trade-off is upfront cost and installation difficulty — porcelain is harder to cut and needs the right adhesive — so finding an installer who has actually done it before matters more than with sandstone.

What Does the Work Involve?

• Excavation and 100 mm compacted MOT Type 1 sub-base.
• Concrete bed (semi-dry mix) on top of the sub-base — usually 40–50 mm.
• Porcelain laid on a slurry primer + adhesive (NOT plain mortar — porcelain has zero porosity so won't bond).
• Slabs laid to a 1:80 fall.
• Resin or flexible mortar jointing — must accommodate slight thermal movement.
• Clean down with neutral patio cleaner.

Typical Costs

Premium porcelain costs more for one reason: better surface graphics. Cheap porcelain looks like cheap porcelain (repetitive patterns); good porcelain genuinely passes for natural stone or aged timber.

How Long Does It Take?

• 15 m² install: 3–5 days (the concrete bed extends timeline).
• 20 m² with steps and cuts: 5–7 days.
• Walkable in 24 hours; full strength 7 days.

DIY or Professional?

Porcelain is one of the harder materials for DIYers. Cutting requires a wet diamond blade; the slurry primer step is unfamiliar; and getting the bedding right is fussier than mortar. Most credible installers will lay porcelain — but ask specifically because half-trained crews still try to use plain mortar (which fails within a year).

Choosing the Right Tradesperson

• Confirm they use a slurry primer (e.g., Marshalls Priora Prime, GftK Primer) on the back of every slab.
• Ask which adhesive they use — recommended brands include Mapei, Larsen, and Sika porcelain-specific products.
• Look at a porcelain job they've done at least 18 months ago — the joints are the tell.
• Get a guarantee covering slab debonding (3+ years is normal).
• Insist on a wet-saw cut, not chop-saw — chop-sawn edges chip on porcelain.

UK Regulations

• Same as other paving: 5 m²+ in a front garden needs drainage or permeable jointing.
• Porcelain itself is non-permeable, so all drainage strategy is in the joint design or perimeter drains.

Common Problems

• Slabs lifting after a winter — almost always missing slurry primer. Won't bond without it.
• Chipped edges — chop-saw cuts. Wet-saw only.
• Slippery rectified finish — choose R11-rated anti-slip texture, not polished.
• Joints failing — using sand-cement mortar; porcelain needs flexible resin or polymer-modified product.
• Hard to clean barbecue grease — actually easier than stone (non-porous) but needs neutral degreaser, not abrasive scouring.
