How to Price a Patio Job in the UK

To price a patio job, measure the site, work out the materials and labour for each stage, allow for overheads and site-specific risks, then add your profit markup. Check the VAT treatment before issuing a written quote that makes the scope, exclusions and final price clear.

The paving itself is only part of the cost. Excavation, waste removal, ground preparation, access and finishing can take as much planning as laying the slabs. This guide shows UK patio installers, landscapers and builders how to build a price from the work involved, rather than relying on a headline rate per square metre.

Start with the total job cost, not a price per square metre

A square-metre rate is useful for comparing similar jobs, but it is a poor starting point for a firm quotation. Two 24m² patios can have very different costs if one has easy access and sound ground while the other needs concrete breakout, extensive cutting and waste carried through a house.

Build your estimate in this order:

1. Direct job costs: paving, aggregates, bedding, jointing, edging, deliveries, waste, plant hire and labour.
2. Allocated overheads: the share of insurance, vehicles, tools, administration and other running costs the job needs to recover.
3. Risk allowance: an amount for identifiable, priced uncertainties within the agreed scope. Do not use this to conceal work that has not been assessed.
4. Markup: the amount added to your cost allowance to arrive at the selling price before VAT.
5. VAT: where applicable, added according to the correct treatment of the work.

If you are applying one markup rate to the entire cost allowance, the basic calculation is:

Selling price before VAT = total cost allowance × (1 + markup percentage ÷ 100)

You might instead build overhead recovery and profit into your labour rates or use different markups for different items. Either approach can work, provided you know what is included and do not recover the same cost twice. The underlying principles also apply when pricing a building job.

Survey the site before fixing the price

A useful patio quote starts with measurements and notes you can refer to later. Take photographs, sketch the layout and record the specification agreed with the customer.

Measure the paving, exposed edges and changes in level

Break an irregular patio into simple shapes, calculate each area and avoid double-counting overlaps. Measure exposed edges separately, because edging is generally priced by length rather than area.

Check the proposed finished levels at doors, paths, lawn edges and inspection covers. Measure any steps, borders or retaining features separately; these can require a different construction method and considerably more labour.

If the same project includes a brick garden wall, price the wall separately so its foundations, masonry and labour are clearly allowed for.

Record the paving product, thickness, laying pattern and joint width. A rectangular layout using standard-sized slabs is not equivalent to a curved patio with a decorative border, even if both cover the same area.

Check access, clearance and existing ground

Walk the entire route from delivery point to installation area. Note the narrowest opening, steps, turns, changes in level and distance materials or spoil must be moved. Consider whether a mini-digger, dumper or mechanical handling equipment can actually reach the work.

Establish whether you are removing turf, existing paving, concrete or other material. Check for soft ground, made-up ground or other conditions that may alter the construction. Where excavation could affect buried services, plan suitable checks and safe working methods; the Health and Safety Executive's HSG47 guidance covers planning, locating services and safe excavation.

Also consider protection for driveways, paths, lawns and internal access routes. Protection and making good take time and should be allowed for where they form part of the job.

Agree the drainage and installation specification

Identify where the finished patio will fall and where runoff can discharge safely. Check the proposed levels against the building's damp-proof course, thresholds, air bricks and other vulnerable details. Do not assume you can simply raise the paving to meet a door.

Confirm whether the price covers drainage alterations, channels, soakaways or changes to inspection covers. If the design is unresolved, investigate it before offering an unconditional fixed price or clearly separate it from the defined work.

Ask who is supplying the paving, who is responsible for delivery and breakages, and whether the customer has approved the actual product and finish.

Calculate excavation, sub-base and waste disposal

Groundworks are a frequent source of underpricing because the finished patio hides most of the effort involved.

Work out the excavation quantity

Start with the proposed finished level and work down through the specified paving, bedding and sub-base. Allow for the existing surface, ground conditions and any additional excavation needed to remove unsuitable material.

For a uniform depth:

In-situ excavation volume (m³) = area (m²) × excavation depth (m)

For example, excavating 24m² to an average depth of 0.17m gives 4.08m³ in situ. That is not necessarily the volume a skip or tipper must carry: excavated material can bulk up, and disposal may be charged by weight, waste category or load size.

Separate concrete breakout from soil excavation. They may require different equipment, working times and disposal arrangements. Obtain actual waste prices rather than guessing what a skip will cost. Builders and landscapers also have waste duty-of-care responsibilities; the GOV.UK waste duty of care code explains these, including checking authorised carriers.

Price the compacted sub-base and installation work

Calculate the required compacted sub-base volume from the area and specified finished thickness. A 24m² patio with a 100mm compacted sub-base needs 2.4m³ of compacted aggregate. Converting that to tonnes requires the supplier's bulk-density and compaction information, plus sensible ordering allowances.

Include delivery and the labour or plant needed to distribute, level and compact the material in layers. The appropriate build-up depends on the ground, intended use and paving system; it should not be selected solely because a depth appeared in an online example.

Cost the bedding system, not just a bag of sand

Check the paving manufacturer's instructions before pricing the laying course. For natural stone, that may mean a full mortar bed, a compatible bonding primer and specific jointing products. Different paving systems have different requirements.

For context, Marshalls' sandstone laying guidance describes a compacted sub-base, priming the backs of slabs and mortar bedding. It is an example of product guidance, not a specification for every patio.

Allow for mixing, material handling, cutting and cleaning as well as the cost of sand, cement, primers and other products.

Price paving, cutting, edging and finishing

Get a delivered quotation for the exact slabs or packs selected. Allow for cutting waste and breakages based on the layout, rather than ordering only the finished patio area.

A poured-concrete patio is a different construction from a patio made with concrete paving slabs. If a customer asks for a “concrete patio”, clarify which they mean before costing it.

For each paving option, check:

• Paving order: finished area plus a defensible allowance for cuts and breakages, based on pack sizes and pattern.
• Edging: measured exposed length, edging units, foundations or restraint details and installation time.
• Jointing: product suitability, joint dimensions, coverage and application time.
• Finishing: cleaning, agreed sealing, making good adjoining ground and removing surplus materials.

The cheapest material per square metre does not automatically produce the cheapest installation. A product requiring specialist cutting or slower handling can increase the labour allowance.

Estimate labour by task, then check the day rate

Instead of taking a generic “days per patio” figure, estimate labour for each stage. Use person-hours or person-days so that a two-person team working for three days is recorded as six person-days, not three.

A practical breakdown is:

1. Protection, setting out and preparing access.
2. Removing the existing surface, excavating and loading spoil.
3. Placing and compacting the sub-base; establishing levels.
4. Mixing bedding, laying slabs and making cuts.
5. Installing edges, pointing and finishing.
6. Cleaning up, removing equipment and making good.

Apply a realistic cost per person-day, including your own labour if you are self-employed. Revisit the estimate where access is slow, the paving is heavy or the pattern involves numerous cuts. Include collection trips and return visits if necessary.

Once you have a total, calculate labour cost ÷ finished patio area as a check against comparable jobs you have completed. Keep direct labour cost separate from the labour selling price you would charge a customer. If the figure looks wrong, revisit the task allowances before arbitrarily reducing it.

For your own labour as a sole trader, use our free day rate calculator to estimate a customer charge-out rate from your ideal take-home pay and annual running costs. The result already allows for those running costs, so check for double-counting when pricing the job.

Add overheads, risk and profit without double-counting

Your price must support the business, not merely reimburse receipts for materials and wages. Vehicle costs, insurance, accountancy, tools, administration and quoting time have to be recovered somewhere.

You can distribute overheads through a loaded labour rate or add a measured overhead allowance for the job. Be consistent. If vehicle running costs are already in your labour rate, do not add their full recovery again elsewhere.

Markup is not the same as profit margin

A 20% markup on £100 of cost gives a £120 selling price before VAT. The £20 difference is 16.67% of the selling price — a 16.67% margin, not 20%.

If you work backwards from a target margin:

Selling price = cost ÷ (1 − target margin as a decimal)

Our separate guide to markup versus margin explains the calculations in more detail. Remember that a calculated margin is not a guarantee of the final profit: your actual costs still matter.

Distinguish a fixed allowance from provisional work

An internal risk allowance is an amount included within a fixed selling price for an identified risk. If the expected expense never arises, it may contribute to profit; if the cost is higher, profit can fall.

A provisional sum is different: it covers work or expenditure not yet sufficiently defined, with its adjustment mechanism set out in the contract. Do not treat every unknown ground condition as automatically chargeable “extra work”. Record the original assumptions, discuss any changed scope and agree the consequences before proceeding.

Worked example: pricing a 24m² sandstone patio

The following is an illustrative costing exercise, not a quoted UK market average or a construction specification. Supplier prices, productivity and ground conditions will differ on real jobs.

Example site and assumptions

A customer wants a 6m × 4m Indian sandstone patio where there is currently turf. Access is straightforward and the site assessment has found suitable ground.

The assumed scope is:

• Finished paving: 24m².
• Paving order: 26.4m², allowing 10% for cuts and breakages.
• Edging: 14 linear metres; the remaining 6m of the perimeter adjoins the house.
• Illustrative build-up: 100mm compacted sub-base, 45mm bedding allowance and nominal 25mm sandstone, totalling 170mm. Verify these dimensions against the selected product and site conditions before using them.
• Excavation: 24 × 0.17 = 4.08m³ in situ, before considering bulking or unsuitable ground.
• Drainage: a suitable fall and discharge route are assumed, with no new drainage installation.
• Labour: ten person-days at an assumed internal labour cost of £180 per person-day.

Steps, retaining walls, service alterations, contaminated waste and works outside the agreed area are excluded. The material quantities below are assumed order allowances that must be checked with suppliers, including the aggregate's delivered tonnage, sand yield and actual pack sizes.

Internal costing worksheet

Every line below uses an illustrative 20% markup. The cost figures are internal business allowances before VAT and assume that input VAT is recoverable where applicable. The customer would normally receive clear descriptions and selling prices, not the underlying cost or markup columns.

For this example, the 4 tonnes of sub-base and 1.6 tonnes of bedding sand are purchasing estimates, not quantities derived from an assumed universal density or mix yield. Confirm the compacted volume, supplier conversion factors, bag sizes, bedding specification and any stock rounding before ordering. Similarly, the stated 12 cement bags need checking against the actual mix design and bag weight.

The ten person-days are total labour input. A team of two might complete the on-site work over roughly five working days if tasks, curing periods, weather and logistics permit; that is not a promised programme.

Check the markup, VAT and rate per square metre

The labour rows total £1,800 in direct labour cost, or £75/m² of finished patio. After the example's markup, the labour selling price is £2,160, equivalent to £90/m² before VAT.

For the whole job, £5,329.20 ÷ 24m² gives £222.05/m² before VAT. That figure includes site-specific overheads, disposal and risk allowances. It should not be treated as a standard rate for every patio.

The £888.20 markup is 16.67% of the selling price before VAT. Actual profitability depends on real costs and whether the risk allowance is used.

VAT note: This example assumes a VAT-registered contractor carrying out standard-rated work. Domestic patio installation will commonly be standard-rated, but the correct treatment depends on the circumstances. HMRC's VAT for builders guidance and VAT Notice 708 explain the rules and exceptions. A contractor who is not VAT-registered should not simply add 20% VAT; their costs may also include input VAT they cannot reclaim.

Turn the costing into a clear customer quotation

A good internal calculation is not enough if the customer cannot tell what they are buying. Your quotation should identify the job, the product and the scope clearly.

For the example patio, describe the agreed area and sandstone specification, removal of turf, excavation, sub-base, bedding, laying, edging, jointing, delivery, spoil removal and making good. Explain the finished levels and drainage provision, and identify any drawings or site notes on which the price relies.

Include:

• The customer and site details, quote number and issue date.
• A clear scope, material specification and priced line items or sensible groups of items.
• Important assumptions, exclusions and any separately identified provisional sums.
• The total price, VAT treatment and total amount payable.
• The quote validity period, proposed payment terms and arrangements for agreeing changes.

A price quoted for a defined scope should not be presented as an open-ended estimate. The guide to quotes versus estimates explains the distinction, while how to write a building quote covers the document structure in more depth.

For work with domestic customers, written terms should not try to remove statutory consumer protections. The Consumer Rights Act 2015 provides protections for services. Cancellation rights under the Consumer Contracts Regulations can depend on how and where the agreement was made. Check the applicable requirements when the customer accepts the work, especially if the contract is agreed at their home or remotely.

Common questions about patio pricing

Should I use a price per square metre or a fixed quote?

For a properly surveyed job with a defined scope, build a fixed selling price from your costs and use the square-metre rate as a cross-check. Identify work that remains genuinely provisional rather than treating all unknowns as included.

How much paving should I order for cutting waste?

Order based on the layout, slab sizes, pack coverage and expected cuts. The 10% allowance in the example is illustrative, not a universal rule. Irregular layouts or complex cuts may need a different allowance.

Do I include waste removal in a patio quotation?

Yes, if you are responsible for it under the agreed scope. Price the expected waste type, volume or weight and disposal arrangements. Make any exclusions for unexpected waste clear and agree additional work properly.

What if excavation reveals poor ground?

Assess the issue and the work needed to address it before proceeding. The response may involve a revised construction design, additional excavation or another agreed solution. Record any proposed change and its cost; do not assume the customer must pay whatever extra amount you decide afterwards.

Final check before sending

Price the patio you actually surveyed. Confirm the quantities, construction method, labour time, access, disposal and overhead recovery, then compare the quote with the agreed specification. A reliable price is one you can explain and deliver — not merely the lowest figure per square metre.
