EXAMPLE AT A GLANCE
This Southampton example prices 3.7 by 6.1 metre patio example with 7 itemised lines and a £2,194.29 illustrative total. It uses fictional prices, a 0% tax input and no markup; verify all inputs for an actual job.
A defined concrete patio job
This fictional project is located in Southampton. Provide a 3.7 by 6.1 metre rectangular concrete patio, about 22 sq m, using a specified 100 mm thickness as an estimating input. Allow for preparation, formwork, base and reinforcement allowances, 2.5 cubic metres of concrete supply, placing and finishing. Confirm the design and ground conditions for the actual site. The written scope is the boundary of the example: a customer should be able to match each planned task to a line in the document, and see where a product choice or hidden condition still needs checking.

Read every amount in pounds
The table reproduces the fixture sent to the app exporter. Each amount is its quantity multiplied by the shown unit rate, rounded to pence. The largest line is Placement and finishing labour at £767.12; that is a part of the total, not a standard price for work of this kind. Check the unit, quantity and scope together before comparing lines with a real supplier or subcontractor quote.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Basic site preparation | 22.3 sq m | £12.90 | £287.67 |
| Base material allowance | 1 lump sum | £200.00 | £200.00 |
| Forms and stakes | 19.5 metres | £10.50 | £204.75 |
| Reinforcement allowance | 1 lump sum | £144.00 | £144.00 |
| Concrete supply allowance | 2.5 cubic metres | £188.30 | £470.75 |
| Placement and finishing labour | 22.3 sq m | £34.40 | £767.12 |
| Clean-up | 1 lump sum | £120.00 | £120.00 |
| Subtotal / example total | £2,194.29 | ||
For a quick cross-check, basic site preparation is 22.3 sq m × £12.90 = £287.67, and forms and stakes is 19.5 metres × £10.50 = £204.75. The sum of all 7 line amounts is £2,194.29. The PDF's 0% tax input and zero markup are example settings; determine the correct inputs for your own work.
What this example assumes
Use one measurement system throughout. In this example, 3.7 metres × 6.1 metres × 0.10 metres gives 2.257 cubic metres of geometric volume. The estimate allows 2.5 cubic metres to purchase; confirm that with the design and supplier.
Work outside the example: No engineered design, difficult excavation, existing slab removal, pumping, retaining work or landscape restoration.
The quantity basis matters. Where a product allowance differs from an installation quantity, the difference reflects this fictional layout or purchase plan and must be checked against the selected product. Existing conditions, safe access and any necessary approvals remain project decisions. Agree how changed measurements or discoveries will be recorded and priced before extra work begins.

Build an estimate for your own job
Start with a measured site record and the customer's selected finish or equipment. Replace all fictional quantities and rates, assign responsibility for supply and waste removal, and check that the exclusions describe the actual boundary. Review each extended amount, total and note in the PDF before sharing it.
- Confirm dimensions and specified thickness.
- Check delivery access and supplier charges.
- Define preparation, base and finish scope.
- Resolve design and drainage requirements separately.

Common questions
How do I calculate concrete volume in cubic metres?
Multiply length by width by specified thickness, all in metres. The 3.7 × 6.1 × 0.10 metre geometry gives 2.257 cubic metres before the separate 2.5 cubic metre purchasing allowance in this example.
Does a patio estimate establish the correct slab thickness?
No. An estimate prices an agreed scope. Thickness, reinforcement and suitability need to be determined for the actual site and intended use.
