A porcelain patio in the UK typically costs between £2,500 and £7,000 installed — noticeably more than the same area in concrete or budget stone. Part of that is the slabs themselves, but a good share of it is the way porcelain has to be laid. If you've priced porcelain by looking at slab prices alone and wondered why the quotes came back higher than you expected, this is where the difference sits.
Porcelain patio cost by size
These are installed prices for porcelain patio installation — excavation, sub-base, primer, laying, jointing and finishing, not just the slabs.
Typical UK installed prices, covering excavation, sub-base, primer, laying and jointing. Actual quotes vary by slab format, access and the number of cuts needed.
| Job size | What's usually involved | Typical cost |
|---|---|---|
| Small porcelain patio, up to around 15m² | A seating area in a standard 600×600 or 600×900 format, straightforward access and few cuts | £2,500 – £4,000 |
| Medium porcelain patio, around 15–30m² | A full garden patio, edging and falls designed in, a mid-range 20mm porcelain range | £4,000 – £5,500 |
| Large or premium porcelain patio, 30m²+ | Larger area, large-format or textured slabs, more cutting, steps or coping, drainage work | £5,500 – £7,000+ |
Installed, that works out at roughly £165 to £230 per square metre. For comparison, a general patio installation in concrete or budget stone typically runs £90 to £170 per square metre — see the patio installation cost guide for that breakdown.
Where porcelain's extra cost actually comes from
Three things, roughly in order of how much they add:
- The slabs. Porcelain is kiln-fired to a dense, non-porous body, and 20mm outdoor grades cost more per square metre than most concrete flags and many sandstones. Large-format and textured ranges cost more again.
- The laying method. Porcelain is non-porous, which is exactly why it stays clean — and exactly why mortar won't grip it on its own. Each slab is normally primed on the back with a slurry bonding coat before it goes onto a full mortar bed. That's an extra material and an extra step on every single slab, and it's the main reason the labour line is higher than for stone.
- Cutting. Porcelain can't be split or cut with an angle grinder without chipping the glazed face, so cuts are made on a wet saw with a diamond blade. A simple rectangle needs few cuts; a patio with a curved edge, a step or an awkward return needs many, and each one takes real time.
What you don't pay for
Porcelain's running costs are close to nothing, and that's worth setting against the higher install price. Because the material is non-porous, it doesn't need sealing — not when it's laid, and not every few years afterwards. Natural stone generally does, and on an Indian sandstone patio sealing is usually quoted as a line of its own or offered as an add-on. Over fifteen or twenty years, that's a real difference, and it's the honest case for paying more upfront.
Porcelain is also far less prone to the staining and algae growth that keep bringing homeowners back to their patios with a pressure washer, and it doesn't fade the way lighter natural stone can.
Other things that move a porcelain quote
- Slab format. Large-format slabs cover ground faster but are heavier, need two people to place and are less forgiving of an uneven bed. Smaller formats are cheaper to handle but mean more slabs and more jointing.
- Thickness. 20mm porcelain is the standard for patios laid on mortar. Thicker 30mm ranges cost more but can be laid on a different build-up in some situations.
- Number of cuts. Curves, steps, drain covers and awkward returns all mean wet-saw time.
- Matching coping or steps. Porcelain step treads, coping and bullnose pieces are priced separately and are usually the most expensive items per square metre in a range.
- Ground conditions and access, exactly as for any other patio — soft ground means a deeper sub-base, and a garden with no side access means everything is carried through the house.
The slurry primer step is the one most often left out of a cheap porcelain quote, and it's the one that decides whether slabs are still firmly bonded in five years. Ask directly whether slabs are primed on the back before bedding, and what the bedding mortar is. A quote that can't answer that is quoting for a stone job on a porcelain patio.

Frequently asked questions
Is porcelain more expensive than natural stone for a patio?
Usually yes on the day, typically running £165 to £230 per square metre installed against roughly £130 to £200 for Indian sandstone. The gap narrows over time, because porcelain needs no sealing and far less cleaning, while natural stone is generally sealed on installation and resealed periodically.
Does porcelain paving need sealing?
No. Porcelain is non-porous, so a sealant has nothing to soak into and nothing to protect against. That's one of its main practical advantages over natural stone, and it means no recurring sealing cost after the patio is laid.
Why is porcelain more expensive to lay than to buy?
Because each slab normally has to be primed on the back with a slurry bonding coat before it goes onto a full mortar bed, and because every cut has to be made on a wet saw rather than split or ground. Both add time on every slab, which is why the labour element of a porcelain quote is higher than for the same area in stone.
Does porcelain paving crack easily?
Outdoor-grade 20mm porcelain is dense and strong, and once bedded properly on a full mortar bed it's very durable. Problems come almost entirely from the bed underneath — a slab supported on dabs or spots rather than fully bedded has unsupported areas, and that's where cracking starts.
