A new patio can transform a garden — but the range of paving materials and labour costs in the UK is wide enough to be genuinely confusing. A 20 m² patio might cost £1,600 in concrete block paving or £4,000 in large-format porcelain, and both can be good value depending on what you want. This guide gives you the real figures, the key differences between materials, and what drives the price.
What Does a Patio Cost?
Most UK homeowners pay between £80 and £200 per m² for a patio, fully installed. The main variables are material choice and ground conditions.
| Material | Supply cost (£/m²) | Installed cost (£/m²) |
|---|---|---|
| Concrete block paving | £20–£40 | £80–£120 |
| Concrete paving slabs | £15–£30 | £75–£110 |
| Porcelain paving (600×600 mm) | £30–£60 | £110–£160 |
| Porcelain paving (large format 900×600+) | £50–£90 | £140–£200 |
| Indian sandstone | £25–£50 | £100–£150 |
| Natural limestone | £40–£70 | £130–£180 |
| Granite setts | £50–£80 | £140–£200 |
Prices are 2026 UK averages. London/South East typically 20–30% higher. Costs assume reasonably accessible, level ground.
Worked Example: 20 m² Patio
| Scope item | Budget option | Premium option |
|---|---|---|
| Sub-base excavation and MOT Type 1 hardcore | £400–£600 | £400–£600 |
| Sand or mortar bed | £150–£250 | £150–£250 |
| Paving material | £400–£700 | £1,000–£1,800 |
| Labour (laying, cutting, pointing) | £600–£900 | £900–£1,400 |
| Total (approx.) | £1,600–£2,500 | £2,500–£4,000 |
Sub-base: The Most Important Cost You Cannot Skip
Regardless of the surface material, a correct sub-base is what determines whether your patio stays flat for 20 years or starts to rock and dip within three. Expect:
- Excavation to 200–250 mm below finished level
- 150 mm compacted MOT Type 1 crushed stone
- 40–50 mm sharp sand or dry-mix mortar bed (depending on material)
Do not lay paving on existing lawn or topsoil. Installers who skip the sub-base are cutting corners that will cost you more in the long run.
Porcelain Paving
Porcelain is the most popular premium choice in the UK right now, and for good reason. It is:
- Extremely low maintenance — does not need sealing, resists moss and staining
- Durable — frost-resistant when properly specified (look for R11 slip-resistance rating for external use)
- Consistent in colour — manufactured to tight tolerances, no colour variation between batches
- Thin but heavy — typically 20 mm for outdoor use (do not use 10 mm indoor tiles outside)
The main disadvantages are cost and the skill required to install it. Large-format porcelain (e.g. 1,200×600 mm) needs a perfectly flat mortar bed — even small deviations cause lippage (tiles sitting at different heights). Labour rates are higher for porcelain than for natural stone.
Key spec to check: porcelain must be rated R11 (or above) for outdoor use under PTV 36 (Pendulum Test Value). Smooth-finish porcelain can be dangerously slippery when wet.
Natural Stone: Indian Sandstone, Limestone, Granite
Natural stone gives a warm, organic look that many homeowners prefer. The main options:
Indian sandstone is the most affordable natural stone and widely installed across the UK. It has a naturally textured surface with good slip resistance. The main maintenance requirement is an annual sealer coat to prevent moss, algae and staining. Colour varies between calibrated (uniform thickness, machine-cut) and riven (handcut, variable thickness) — calibrated is easier to lay.
Limestone has a cleaner, more contemporary look than sandstone. Quality varies enormously by source — look for low water-absorption figures (under 3%) for frost resistance. Limestone can etch from acidic cleaners.
Granite setts are extremely durable but labour-intensive to lay. More commonly used for driveways or edging than full patio surfaces. They last 50+ years with minimal maintenance.
Concrete Block Paving and Slab Paving
Concrete block paving (CBP) — the interlocking blocks used on driveways — is a cost-effective and durable choice for patios too. It handles heavy loads, any individual block can be lifted and relaid if drainage work is needed, and it comes in a wide range of colours. Aesthetically it reads more as “driveway” than “garden patio,” which some homeowners find off-putting.
Plain concrete slabs from builders’ merchants are the cheapest option but look functional rather than attractive. They crack more readily than blocks or porcelain over long service.
Drainage: Do Not Forget It
Building Regulations Part H and the general principle of sustainable urban drainage mean that any hard surface over 5 m² in a front garden requires permeable surfacing or adequate drainage provision. Rear gardens are less strictly controlled but should not drain onto a neighbour’s land.
Porcelain and natural stone laid solid onto a mortar bed are impermeable. Options:
- Lay on a 10–15 mm open-jointed bed with fine gravel joints (some drainage)
- Install a channel drain at the low point
- Use permeable jointing compounds (available from specialist paving suppliers)
Pointing and Jointing
The joint compound between paving affects maintenance requirements significantly:
- Kiln-dried sand (CBP) — refill every few years as it washes out; weeds can colonise
- Wet-applied mortar — solid and durable but can crack and look untidy after 10–15 years
- Polymeric (resin) pointing — flexible, weed-resistant, bonds well; add £5–£10/m² to costs; the best choice for porcelain and premium natural stone
Choosing the Right Material
| If you want… | Best choice |
|---|---|
| Lowest total cost | Concrete block paving or concrete slabs |
| Minimum maintenance | Porcelain (20 mm, R11 rated) |
| Natural, warm look | Indian sandstone or limestone |
| Best long-term durability | Granite or quality porcelain |
| Easier DIY installation | Block paving or standard concrete slabs |
How to Find a Good Paving Contractor
Get three written quotes specifying the exact material (size, thickness, finish), sub-base depth, and pointing type. Avoid anyone who does not excavate — existing hard surfaces rarely provide an adequate base. Check that they are registered with a trade body (MPA or BALI) or ask for references on similar-scale work. Pay a small deposit only; avoid paying in full before work starts.
