How Much Does Granite Paving Installation Cost per Square Metre?
For early budgeting, allow approximately £100–£140 per m² for a straightforward granite slab patio, including paving, normal groundwork, installation materials and labour. A more detailed layout may require £120–£160 per m². Access, excavation, drainage and the amount of cutting are the main factors that change the finished price.
How Much Is the Labour to Lay Granite Paving?
Use £50–£80 per m² as an initial labour allowance for straightforward granite slab work. Confirm whether the contractor's figure covers the full job's labour or only laying onto a prepared base. Labour included in a complete installation quotation must not be added to that quotation again.
How Much Does a 25 m² Granite Patio Cost?
At an installed budget of £100–£140 per m², a 25 m² granite patio works out at approximately £2,500–£3,500. The worked example below totals £3,300, equivalent to £132 per m². It separates paving, materials, waste and labour so you can see where the money goes.
Does the Granite Slab Price Include Installation?
No. Paving Slabs UK's product prices cover the paving supply under the stated delivery terms. Excavation, waste disposal, sub-base construction, bedding, priming, jointing and laying are separate project costs. A contractor may combine these into one supply-and-install quotation.
Budget basis: The installation figures in this guide are planning allowances, not fixed installation prices offered by Paving Slabs UK or a national survey average. Treat them as total customer budgets, including VAT where applicable. Compare contractor quotations on the same VAT-inclusive basis. Major drainage works, retaining structures and difficult demolition require separate allowances.
Granite Paving Installation Budgets at a Glance
| Project Type | Installed Planning Budget | Main Cost Drivers |
|---|---|---|
| Straightforward granite slab patio | £100–£140 per m² | Regular layout, manageable access and normal preparation. |
| Detailed granite slab layout | £120–£160 per m² | Additional cuts, borders and more involved setting-out. |
| Granite setts for pedestrian paving | £130–£180 per m² | More individual units, alignment and jointing work. |
| Granite sett driveway | £150–£200+ per m² | Vehicle-bearing construction, edge restraint and drainage. |
These are alternative project budgets, not cost items to add together. A narrow sett border is often better priced by the linear metre or as a complete detail than by applying the rate for a full sett-paved area.
Understand the Three Different Price Types
- Supply only: the paving products, with the stated packing and delivery terms.
- Labour only: the contractor's work, with the included activities defined in writing.
- Supply and installation: the agreed combination of products, preparation, materials, labour and finishing.
A £25-per-m² slab price and a £130-per-m² finished patio price describe different purchases. To compare two contractors, compare the work included in their quotations as well as the total.
Granite Material Prices and the Quantity You Actually Buy
On 15 September 2026, our Silver Grey Granite Paving Slabs 900 × 600 × 20 mm were advertised from £25.19 per m², based on the full-pack option. This is a dated product price, not an installation rate.
Calculate the order quantity from the measured area, layout and cuts, then select the available pack combination. A 25 m² patio with a 10% planning allowance needs 27.5 m² before rounding to the appropriate packs. The order total should come from those pack prices rather than simply multiplying the patio area by the headline rate.
Keep steps, coping and borders as separate quantities. Our granite paving material price guide covers the product-price side in more detail.
All listed prices are VAT inclusive + Free UK Delivery*.
*Product delivery is included within the stated delivery zone. Postcode surcharges may apply. This does not include installation or on-site movement of materials into the garden.
What Makes Up the Installation Cost?
Excavation, Demolition and Waste Removal
The existing surface determines the starting workload. Removing turf and soil is different from breaking out a concrete base. Excavation depth, the volume of spoil and the distance to the loading point all affect the cost.
Ask whether the quotation includes machine hire, skips or grab collection, disposal charges and the labour needed to move waste. Separate these clearly when comparing an itemised quote.
Sub-Base Materials and Compaction
The sub-base provides stable support beneath the paving. Its cost includes the specified aggregate, delivery, spreading and compaction. Ground conditions and intended use determine the construction required.
For a rigid patio, compacted MOT Type 1 is a common choice. Confirm the proposed compacted depth and any geotextile requirement in the quotation. The granite sub-base and drainage guide explains these construction decisions.
Bedding, Primer and Jointing
A bonded granite slab patio needs full mortar-bed support and a compatible slurry primer or bonding bridge on the slab underside. Budget for sand, cement, primer, mixing and handling, together with the chosen jointing material.
Jointing quantities depend on slab format, joint dimensions and the product's coverage. Include the time needed to apply it cleanly and remove residue from the paving face.
Laying, Cutting and Finishing Labour
The labour allowance should identify the activities included: excavation, moving materials, preparing the base, mixing mortar, laying, cutting, jointing and cleaning down. Some contractors include all these activities in one labour figure; others separate groundwork from the paving installation.
Granite's hardness makes suitable diamond cutting equipment important. Complex edges increase cutting time, blade use and offcuts. Larger slabs also need planned handling, particularly in restricted spaces.
Drainage, Edges and Level Changes
Drainage channels, outlets, threshold details, steps and edge restraints can add substantial work beyond the main paved area. Price these as identifiable items so they do not disappear inside a vague square-metre rate.
Confirm the drainage destination as well as the channel itself. A finished patio needs both suitable falls and a practical route for the water to leave.
Worked Example: A 25 m² Granite Patio
This is an illustrative cost model for a rectangular patio with manageable access, normal excavation and no new drainage network, steps or retaining walls. The paving allowance includes provision for cuts and pack selection. Each row represents a separate cost; labour appears only once.
| Cost Item | Example Allowance |
|---|---|
| Granite paving purchase allowance, including cuts and pack selection | £750 |
| Plant hire and waste disposal, excluding labour | £300 |
| Sub-base materials and their delivery, excluding labour | £250 |
| Bedding, primer and jointing materials, excluding labour | £250 |
| All site labour: preparation, handling, laying, cutting and finishing | £1,750 |
| Total project budget | £3,300 |
| Cost per finished square metre | £132 |
The calculation is £750 + £300 + £250 + £250 + £1,750 = £3,300. Dividing by the finished patio area of 25 m² gives £132 per m². Replace the allowances with your actual product basket and contractor quotation to build a project-specific budget.
Divide by the Finished Patio Area
The installed cost per square metre is the total project cost divided by the area being paved. Extra material bought for cuts, pack rounding and spare pieces belongs in the cost, but does not increase the finished patio area used in the calculation.
Indicative Budgets for Different Patio Sizes
Applying the straightforward slab-patio allowance of £100–£140 per m² gives:
| Finished Patio Area | Initial Project Budget |
|---|---|
| 20 m² | £2,000–£2,800 |
| 25 m² | £2,500–£3,500 |
| 30 m² | £3,000–£4,200 |
| 40 m² | £4,000–£5,600 |
Small jobs often have a higher unit cost because transport, equipment and mobilisation are spread across fewer square metres. Larger areas can use labour more efficiently, although difficult access and complex details still affect the total.
Why Granite Setts Usually Cost More to Lay
Setts involve more individual units per square metre than slabs. Positioning, aligning and adjusting those units takes time, especially in curves, fans and detailed patterns. Jointing also becomes a larger part of the job.
A sett driveway adds vehicle-bearing groundwork, suitable restraint and drainage to that workload. Price the complete construction rather than assuming the cost of a pedestrian patio applies to a driveway.
How to Compare Installation Quotes
Ask each contractor to price the same area and design. The written scope should identify:
- The exact paving and purchased quantity.
- Excavation, demolition and waste disposal.
- Sub-base material and compacted depth.
- Full bedding, primer and jointing system.
- Drainage, edges, steps and access-cover details.
- All labour, plant and material-handling costs.
- VAT, exclusions and provisional allowances.
Published patio cost guides also use different scopes. Checkatrade's guide labels its main comparison table as costs plus VAT, while MyBuilder's guide discusses material costs and daily labour rates. These provide general context; compare their inclusions before applying a figure to granite work.
Reduce Complexity to Control the Budget
A straightforward shape, a slab format suited to the dimensions and well-planned access can reduce installation time. Finalise the layout, drainage and edge details before ordering, and coordinate the delivery so materials can be handled efficiently.
Keep the specified foundation, full bedding and bonding system in place. The effective saving comes from fewer awkward cuts, less rehandling and fewer design changes during construction.
Plan the products and installation together: Compare the granite paving range, then give your contractor the selected dimensions, pack information and layout. This makes the installation quotation easier to price accurately.
Questions About Granite Installation Prices
Is £100 per m² the labour charge or the finished patio cost?
In this guide, £100–£140 per m² is the planning range for a straightforward finished granite slab patio, including paving, normal preparation, installation materials and labour. It is not a labour-only rate.
Should I add labour to a supply-and-install quotation?
No. If the quotation already includes the agreed labour, adding a separate labour allowance would count the same cost twice. Check the written inclusions and add only genuinely excluded work.
Does the 10% cutting allowance apply to every patio?
No. Ten per cent is the planning assumption used in the quantity example. The required allowance depends on the layout, cuts, pack contents and spare pieces wanted. Confirm the order quantity against the actual design.
Why can a small granite patio cost more per square metre?
Equipment, transport, setup and waste arrangements have costs even on a small job. Spread across a smaller paved area, these can produce a higher installed cost per square metre.
Can I reuse an existing patio base to save money?
An existing base can reduce preparation work if it is suitable for the new construction. Ask the installer to assess its condition, depth, levels and drainage before including that saving in the quotation.
Are the installation budgets VAT inclusive?
The planning allowances and worked example in this guide are expressed as total customer budgets, including VAT where applicable. Ask contractors to confirm the total payable, since some quotations and published guides show prices before VAT.
