EXAMPLE AT A GLANCE
This fictional Exeter patio drainage channel installation project has 7 itemised lines and an illustrative £3,562.26 total. The app-exported PDF, first-page preview, measurement basis, scope boundaries and matching UK estimating guide let you inspect every quantity and rate.
What this example covers
This fictional job is set in Exeter and concerns one paved patio edge. Install a surface drainage channel along an existing paved patio edge and connect to a confirmed suitable outlet. The estimate is a bounded document: the customer should be able to compare the described work with its measured lines, product allowances and exclusions. The matching UK guide explains how to prepare those inputs.

Itemised patio drainage channel installation example
These 7 lines reproduce the app-exported PDF exactly. The largest is Channel and grate allowance at £1,365.89; this is one fictional component, not a typical price. Read each quantity with its unit: area, length, time, count and lump sum describe different work and must not be interchanged.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Levels and outlet survey | 1 lump sum | £152.00 | £152.00 |
| Paving cut and lift | 13.7 metres | £36.70 | £502.79 |
| Trench excavation | 13.7 metres | £26.20 | £358.94 |
| Channel and grate allowance | 13.7 metres | £99.70 | £1,365.89 |
| Drain connection parts | 1 lump sum | £224.00 | £224.00 |
| Channel setting labour | 13.7 metres | £47.20 | £646.64 |
| Paving reinstatement and clean | 1 lump sum | £312.00 | £312.00 |
| Illustrative total | £3,562.26 | ||
The table separates the named product or material allowances from labour and site tasks wherever the scope needs that distinction. Before replacing a rate, check whether the product allowance includes delivery, waste, fixings and the selected specification.
How the total is calculated
Paving cut and lift is 13.7 metres × £36.70 = £502.79. Trench excavation is 13.7 metres × £26.20 = £358.94. The other lines follow the same calculation and sum to £3,562.26. Each fixture line lands on an exact penny, so the native PDF total equals the sum of the displayed line amounts.
Measurement to check: Measure channel run, paving cut length, invert level and available outlet route. Selection to check: Keep channel units, grates and pipe fittings distinct from excavation and reinstatement. The 0% tax field and zero markup are example document inputs, not an instruction for a live quote. Decide the correct settings for your own business and job.
Assumptions and exclusions
Confirm outlet permissions and levels before cutting paving.
Outside this stated scope: No new soakaway, sewer repair or large-area repaving.
No workable outlet or insufficient fall requires redesign rather than an assumed connection. A changed condition should lead to a newly measured quantity, explicit revised allowance or separately agreed task. Keep the customer informed of which figure changed and why before producing another PDF.
