A professionally laid porcelain patio in the UK costs considerably more than the porcelain paving alone. The slabs are only the visible finish. Underneath them are the excavation, compacted sub-base, sharp sand and cement mortar, slurry primer, jointing material, waste removal and several days of skilled work.
For a straightforward residential garden completed during the normal landscaping season, a sensible working budget is generally around £140 to £190 per m² including materials, labour and VAT. Small patios often cost more per square metre because delivery, plant hire, waste removal and contractor mobilisation still have to be paid for.
Restricted access, old concrete, poor ground, drainage work, steps, complicated cuts or premium porcelain can push the finished cost above £200 per m². Large, open and uncomplicated patios may fall below the main range once the fixed costs are spread over a greater area.
This guide breaks down the likely cost of professionally installing porcelain paving over areas from 20 m² to 100 m². These are budgeting figures rather than fixed quotations. No sensible landscaper should give a firm price without checking the access, ground conditions, existing surface, levels and drainage.
How Much Does a Porcelain Patio Cost?
For an ordinary UK back garden with reasonable access, normal excavation and a straightforward rectangular layout, the following figures provide a practical starting point.
| Patio area | Typical installed budget | Likely cost per m² |
|---|---|---|
| 20 m² | £3,000–£4,200 | £150–£210 |
| 30 m² | £4,200–£5,700 | £140–£190 |
| 40 m² | £5,400–£7,200 | £135–£180 |
| 50 m² | £6,600–£8,750 | £132–£175 |
| 60 m² | £7,800–£10,200 | £130–£170 |
| 70 m² | £9,100–£11,900 | £130–£170 |
| 80 m² | £10,200–£13,600 | £128–£170 |
| 90 m² | £11,500–£15,300 | £128–£170 |
| 100 m² | £12,800–£17,000 | £128–£170 |
The lower end assumes a flat and open garden, good machine access, no existing concrete, a standard laying pattern and ordinary regional labour rates.
The upper end allows for more difficult access, additional excavation, higher regional labour costs, awkward cutting, drainage alterations or more expensive porcelain. A difficult London project involving hand excavation, concrete removal and premium paving can exceed the figures shown.
What Is Included in the Installed Cost?
A proper porcelain patio quotation should cover considerably more than supplying and laying the slabs. For an ordinary domestic installation, the price will normally include:
- Initial site preparation and setting out
- Removal of turf, soil or existing paving
- Excavation to the required construction depth
- Removal and lawful disposal of excavated spoil
- Geotextile membrane where ground conditions require it
- MOT Type 1 sub-base
- Compaction of the sub-base in suitable layers
- Sharp sand and cement for a full mortar bed
- Slurry primer applied to the full reverse face of every slab
- 20 mm outdoor porcelain paving
- Cutting, alignment and formation of suitable falls
- Exterior jointing compound or porcelain grout
- Plant hire, cutting discs and ordinary consumables
- Skilled installation labour
- VAT where the contractor is VAT registered
A quotation that only states a slab price and a laying rate is not a complete patio price. Much of the real cost is in the work that disappears underneath the finished paving.
Porcelain Paving Material Cost
Good-quality 20 mm outdoor porcelain paving is widely available in the UK. Standard ranges commonly start in the low £20s per square metre, while full-body porcelain, specialist finishes and premium designs generally cost more.
For budgeting purposes, a sensible material allowance is:
- Budget outdoor porcelain: approximately £20–£25 per m²
- Typical mid-market porcelain: approximately £25–£35 per m²
- Premium porcelain: approximately £35–£60+ per m²
Customers comparing realistic stone-effect colours can consider products such as Kandla Grey Porcelain Paving 900 × 600. For a more consistent full-body construction, the Light Grey Dolomite Series Porcelain provides another option.
The quantity ordered must be greater than the measured finished area. A straight rectangular patio normally needs approximately 7–10% additional paving for cutting, selection and accidental damage.
Complex patterns, diagonal layouts and patios containing several corners, borders or narrow sections may require a waste allowance of 12–15% or more.
| Finished area | Quantity with 10% allowance | Slab cost at £25/m² | Slab cost at £35/m² |
|---|---|---|---|
| 20 m² | 22 m² | £550 | £770 |
| 30 m² | 33 m² | £825 | £1,155 |
| 40 m² | 44 m² | £1,100 | £1,540 |
| 50 m² | 55 m² | £1,375 | £1,925 |
| 60 m² | 66 m² | £1,650 | £2,310 |
| 70 m² | 77 m² | £1,925 | £2,695 |
| 80 m² | 88 m² | £2,200 | £3,080 |
| 90 m² | 99 m² | £2,475 | £3,465 |
| 100 m² | 110 m² | £2,750 | £3,850 |
These figures cover the porcelain paving only. They do not include delivery, aggregates, mortar, primer, jointing, excavation, waste removal or labour.
MOT Type 1 Sub-Base Cost
For a normal pedestrian patio laid over suitable natural ground, landscapers commonly install approximately 100 mm of properly compacted MOT Type 1.
Weak, disturbed, waterlogged or made-up ground may require deeper excavation, a separating membrane or an increased sub-base depth. The final specification must be based on the ground actually found on site.
At 100 mm compacted depth, every square metre requires approximately 0.10 m³ of compacted sub-base. Using a working compacted density of roughly 2.0–2.1 tonnes per cubic metre, the approximate requirement is 200–210 kg per m².
| Patio area | Approximate Type 1 requirement |
|---|---|
| 20 m² | 4.0–4.2 tonnes |
| 30 m² | 6.0–6.3 tonnes |
| 40 m² | 8.0–8.4 tonnes |
| 50 m² | 10.0–10.5 tonnes |
| 60 m² | 12.0–12.6 tonnes |
| 70 m² | 14.0–14.7 tonnes |
| 80 m² | 16.0–16.8 tonnes |
| 90 m² | 18.0–18.9 tonnes |
| 100 m² | 20.0–21.0 tonnes |
Small quantities are often supplied in bulk bags. Loose tipped loads are usually more economical on larger projects, provided the delivery vehicle can reach the property and there is a suitable place to tip the aggregate.
A low loose-load price is of little benefit when the lorry cannot approach the site or every tonne must be moved a long distance by wheelbarrow.
Sharp Sand and Cement Cost
Outdoor porcelain should normally be laid on a continuous full mortar bed rather than spots, rings or dabs. A traditional paving specification uses a semi-dry mortar mixed at approximately four parts washed sharp sand to one part cement.
For an average mortar-bed depth of 35 mm, every square metre requires approximately 0.035 m³ of mixed mortar. Actual consumption varies because the mortar bed is also used to form the required falls and correct minor differences in the compacted base.
| Patio area | Approximate sharp sand | Approximate 25 kg cement bags |
|---|---|---|
| 20 m² | 0.9–1.0 tonnes | 8–9 bags |
| 30 m² | 1.3–1.5 tonnes | 12–13 bags |
| 40 m² | 1.8–2.0 tonnes | 16–18 bags |
| 50 m² | 2.2–2.4 tonnes | 20–22 bags |
| 60 m² | 2.7–2.9 tonnes | 24–26 bags |
| 70 m² | 3.1–3.4 tonnes | 28–31 bags |
| 80 m² | 3.6–3.9 tonnes | 32–35 bags |
| 90 m² | 4.0–4.3 tonnes | 36–39 bags |
| 100 m² | 4.5–4.8 tonnes | 40–44 bags |
Use sharp sand suitable for paving mortar. Soft building sand is not a direct substitute for a properly graded sharp-sand bedding mix.
Slurry Primer Cost
Porcelain has very low water absorption. Ordinary bedding mortar does not form a reliable mechanical bond to the reverse of an unprimed porcelain slab.
The complete reverse face of every slab should therefore receive a fresh, full and even coat of specialist slurry primer immediately before the slab is placed onto the wet mortar bed.
A 20–25 kg bag of professional slurry primer commonly covers approximately 15–19 m², depending on the product, reverse texture and application thickness. For purchasing purposes, it is prudent to allow approximately one bag for every 15–17 m².
| Patio area | Likely primer requirement |
|---|---|
| 20 m² | 2 bags |
| 30 m² | 2 bags |
| 40 m² | 3 bags |
| 50 m² | 3–4 bags |
| 60 m² | 4 bags |
| 70 m² | 5 bags |
| 80 m² | 5–6 bags |
| 90 m² | 6 bags |
| 100 m² | 6–7 bags |
Slurry primer should not be treated as an optional extra. Omitting it may save a small amount during installation, but loose slabs and failed adhesion are much more expensive to correct afterwards.
Porcelain Jointing Compound Cost
Rectified outdoor porcelain is commonly installed with joints of approximately 5 mm, although the slab supplier’s instructions and the jointing-product requirements should always be checked.
Jointing coverage is determined by:
- Slab length
- Slab width
- Joint width
- Joint depth
Large 900 × 600 mm slabs contain far fewer linear metres of joint than small-format paving. It is therefore incorrect to apply a generic coverage rate intended for small setts or mixed-size paving.
For 900 × 600 mm porcelain with joints around 5 mm wide and approximately 20 mm deep, a practical working allowance is commonly around 20–30 m² per 12.5–15 kg unit. Actual coverage depends on the chosen product and the true joint profile.
| Patio area | Practical purchasing allowance |
|---|---|
| 20 m² | 1 unit |
| 30 m² | 1–2 units |
| 40 m² | 2 units |
| 50 m² | 2–3 units |
| 60 m² | 3 units |
| 70 m² | 3–4 units |
| 80 m² | 4 units |
| 90 m² | 4–5 units |
| 100 m² | 5 units |
Always use the manufacturer’s coverage calculator before ordering. Brush-in compounds, dry-applied porcelain jointing products and cementitious grouts do not share the same coverage, curing conditions or installation method.
Labour Cost for Laying Porcelain Paving
Porcelain is not difficult because it is mysterious. It is difficult because it is unforgiving. The levels and falls must be correct, the mortar coverage must be continuous, the reverse of every slab must be primed and the joints must remain straight and consistent.
A competent installation team will normally include at least one skilled paving installer and one labourer. Their work includes excavation, moving aggregates, compacting the base, mixing mortar, priming slabs, cutting, laying, cleaning and jointing.
Typical labour allowances may fall within the following broad bands:
- Straightforward regional installation: approximately £50–£65 per m²
- Typical professional installation: approximately £65–£90 per m²
- Restricted or complicated installation: approximately £90–£130+ per m²
These are broad labour and contractor allowances rather than employee wage rates. A legitimate paving contractor must also cover vehicles, fuel, insurance, machinery, administration, travelling time, warranty risk and profit.
Regional Labour Differences
Installation prices vary considerably across the UK. London and much of South East England usually sit towards the upper end of the range because labour, parking, waste disposal, plant delivery and general operating costs are higher.
The Midlands are often close to the national average. Parts of Northern England and Wales may be lower, although rural delivery distances can offset some of that saving. Scotland’s central belt may remain close to national pricing, while Highland and island projects can attract substantial transport and delivery surcharges.
| Region | Typical position against national pricing | Main cost pressure |
|---|---|---|
| London and South East | Often 25–45% higher on labour-related costs | Labour, parking, skip hire and plant delivery |
| Midlands | Generally near the national average | Normal labour and transport costs |
| Northern England | Often 5–15% below the national average | Usually lower labour and disposal costs |
| Wales | Often below average outside major cities | Rural delivery can increase the final cost |
| Scotland | Varies considerably by location | Highland and island transport surcharges |
The same porcelain slabs can be sold at a similar national price while the completed installation varies considerably because of local labour, access, transport and waste-disposal costs.
Excavation and Ground Preparation
A patio installed over soil may require an overall excavation depth of approximately 150–200 mm, depending on the porcelain thickness, mortar bed, sub-base depth and required finished level.
The excavation must allow the finished paving to remain safely below the property’s damp-proof course and must provide sufficient fall for surface water to move away from the building.
Ground preparation may include:
- Removing turf and topsoil
- Breaking out an existing patio
- Removing soft or unstable material
- Installing a geotextile membrane
- Filling and compacting low areas
- Building the sub-base in layers
- Forming falls before laying begins
Where a mini digger cannot enter the garden, excavation and aggregate movement may have to be completed by hand. This can remove a plant-hire charge but add several days of labour.
Skip Hire and Soil Removal
Waste removal should be included clearly in an all-in porcelain patio quotation. It should not appear unexpectedly as an extra charge after excavation has started.
An 8-yard builders’ skip commonly costs around £250–£400 in many parts of the UK. Prices in London and other high-cost areas may be higher. A permit may also be required when the skip is placed on a public road rather than private property.
Depending on the site, waste may be removed using:
- A builders’ skip
- A maxi skip
- A grab lorry
- A licensed tipper vehicle
- Separate soil and hardcore collections
Excavated soil occupies more space after it has been dug out. The material breaks up and increases in loose volume, so the waste requirement should not be calculated only from the original compacted ground volume.
A single skip may serve some small patios, but larger projects can require several skips or one or more grab-lorry collections. Heavy concrete, clay soil and mixed waste may also carry different disposal charges.
Plant Hire and Consumables
Depending on the scale and access, the contractor may require:
- A mini digger
- A vibrating plate compactor
- A cement mixer or forced-action mixer
- A bridge saw or suitable porcelain cutter
- Diamond cutting blades
- A laser level and setting-out equipment
- Wheelbarrows, buckets and cleaning equipment
- Fuel and ordinary site consumables
Plant hire is normally a fixed or stepped cost rather than a simple square-metre charge. Hiring and delivering a mini digger for a 20 m² patio may cost almost as much as hiring it for a 35 m² patio when both excavations fit within the same hire period.
Why Does a Small Porcelain Patio Cost More per Square Metre?
A 20 m² patio normally has a higher effective square-metre price than a 60 m² or 100 m² patio because fixed costs are spread over a smaller finished area.
The contractor still has to:
- Visit and measure the site
- Prepare the quotation
- Arrange slab and aggregate deliveries
- Transport tools and machinery
- Set out levels and falls
- Arrange waste removal
- Clean the paving and complete the joints
These costs do not fall in direct proportion to the size of the patio. Larger projects use more material and labour, but the effective cost per square metre normally reduces as mobilisation, machinery and delivery charges are spread across a greater area.
What Can Increase the Installation Price?
Removing an Existing Concrete Patio
Breaking out thick or reinforced concrete requires additional machinery, cutting equipment, labour and waste capacity. Concrete is heavy, so disposal charges rise quickly.
Restricted Garden Access
If machinery cannot pass through the side entrance, the excavation may need to be completed by hand. Every tonne of Type 1, sand and waste may then have to be moved by wheelbarrow.
Poor Ground Conditions
Soft clay, disturbed ground, tree roots and waterlogging may require deeper excavation, geotextile separation, additional Type 1 or drainage improvements.
Drainage and Finished Levels
The patio must shed water safely and must not bridge the damp-proof course. Linear drainage channels, downpipe connections, manhole adjustments and changes of level are additional work.
Steps and Retaining Walls
Steps, raised patios, retaining walls and raised beds should be priced separately. They require foundations, walling materials, additional cutting and considerably more labour.
Complex Cutting
Curves, diagonal layouts, narrow borders and numerous corners increase both labour and slab wastage. A plain rectangular patio is normally the most economical arrangement.
Premium or Large-Format Porcelain
Premium finishes and larger slabs can increase both material and handling costs. Large slabs are heavier and may require two installers to position them accurately without disturbing the mortar bed.
London and South East England
Labour, parking, waste disposal, machinery transport and general business costs are usually higher in London and parts of South East England. Regional quotations can therefore differ substantially even when the same porcelain product is specified.
What Is Usually Missing from a Cheap Patio Estimate?
Very low online estimates often omit one or more of the following:
- VAT
- Porcelain delivery
- Aggregate delivery
- Excavation
- Skip hire or soil removal
- Mini-digger delivery and hire
- Compactor hire
- Slurry primer
- Jointing compound
- Drainage work
- Cutting blades and consumables
- Contractor overhead and profit
A figure described as “laying from £60 per m²” may refer only to laying labour on a base that has already been excavated, filled and compacted. It should not be compared with a complete quotation covering groundworks, materials, waste removal and VAT.
How to Compare Porcelain Patio Quotations
Do not compare quotations by looking only at the final number. Check that each contractor has priced the same construction specification.
A proper quotation should confirm:
- The excavation depth
- The compacted sub-base depth
- The type of sub-base aggregate
- The mortar-bed depth and mix
- Whether slurry primer is included
- The intended joint width
- The jointing product
- The required falls and drainage arrangement
- Who is responsible for waste removal
- Whether plant hire is included
- Whether VAT is included
- Whether porcelain supply and delivery are included
Two quotations may appear to describe the same patio while allowing for completely different excavation depths, sub-base construction and waste arrangements. Those differences usually explain why one quotation is considerably cheaper.
How Much Should You Budget?
For an ordinary professionally installed porcelain patio in a reasonably accessible UK garden, allow approximately £140–£190 per m² as a practical starting budget.
A straightforward large patio may fall below this range per square metre. A small, restricted or technically complicated project can exceed £200 per m².
The porcelain paving itself commonly represents only around 15–25% of the completed project cost. Labour, excavation, sub-base construction, bedding materials, waste removal and site logistics normally account for the larger share.
The old rule still applies: the finish is only as good as the work underneath it. Porcelain laid carefully on a properly compacted base and a full primed mortar bed should provide many years of service. Porcelain laid cheaply over an inadequate base will not be rescued by the quality of the slab.
Porcelain Patio Cost FAQs
How much does a 20 m² porcelain patio cost?
A typical 20 m² porcelain patio may cost approximately £3,000–£4,200 including paving, ordinary ground preparation, bedding materials, slurry primer, jointing, waste removal, labour and VAT. Restricted access, concrete removal or drainage work can increase the price.
How much does a 40 m² porcelain patio cost?
A professionally installed 40 m² porcelain patio will commonly require a budget of approximately £5,400–£7,200. The final price depends on the porcelain selected, excavation requirements, garden access and regional labour rates.
How much does a 60 m² porcelain patio cost?
For a standard 60 m² project, a reasonable initial budget is approximately £7,800–£10,200. Larger patios normally cost less per square metre because fixed delivery, machinery and mobilisation costs are spread over a greater area.
How much does a 100 m² porcelain patio cost?
A professionally installed 100 m² porcelain patio may require a budget of approximately £12,800–£17,000. Complex drainage, steps, retaining walls, difficult access or premium porcelain can take the project above this range.
Does the patio price include skip hire?
A genuine all-in quotation should clearly state whether skip hire, grab-lorry collection or another form of licensed waste removal is included. Customers should not assume that excavation waste is covered unless it appears in the written quotation.
Are porcelain patio costs higher in London?
They usually are. London and parts of South East England commonly have higher labour, parking, skip-hire and plant-delivery costs. The porcelain itself may be similarly priced nationwide, but the site and installation costs can be considerably higher.
Does porcelain paving need slurry primer?
Yes. Outdoor porcelain has very low water absorption, so the complete reverse face of every slab should be coated with a suitable slurry primer before it is placed onto the fresh mortar bed.
Can porcelain paving be laid directly on sand?
Porcelain paving should not normally be laid loose on a simple sand bed in the same way as block paving. A conventional UK installation uses a properly compacted sub-base and a continuous mortar bed, with slurry primer applied to the reverse of the slabs.
Is porcelain paving more expensive to lay than sandstone?
Porcelain can cost more to install because it requires accurate setting out, suitable cutting equipment, consistent joints, full mortar coverage and slurry primer. The paving material may be competitively priced, but the installation should not be treated as a basic slab-laying job.
Why do porcelain patio quotations vary so much?
Quotations vary because contractors may be pricing different excavation depths, access conditions, waste quantities, sub-base specifications, porcelain products and drainage requirements. VAT status, region and whether plant hire is included also affect the final figure.
