Close-board / panel fencing: calculator for UK builders
Answer the measurements this calculation needs and JobBosh works out the materials with wastage and pack rounding, the labour hours by role, the plant, the waste and the site needs - then prices them from your own figures, a supplier's quotation or a dated price you record. Free, no account needed to start.
What it works out
- Material: Slotted concrete posts; Fence panels 1.8 m; Concrete gravel boards; Postcrete (20 kg)
- Labour: Erect fence; Remove existing fence and posts
- Waste: Old fence (timber, concrete)
The questions it asks
| Question | Unit / choices | Required? | Help |

The norms behind it, with their sources
Coverage, productivity and wastage defaults you can edit; each carries where it comes from and is shown as assumed until your own benchmark replaces it.
| Norm | Value | Source | Tier |
|---|---|---|---|
| Post spacing (6 ft panels) | 1.83 m | standard panel | assumed |
| Postcrete per post | 2 bags/post | typical manufacturer figure for a 600 mm hole | assumed |
| Dig, set post, fit panel/gravel board per bay | 1.5 hr/bay | trade practice | assumed |
| Remove old fence per metre | 0.15 hr/m | trade practice | assumed |
A worked example
Answers used: Fence length 4 m; Height 1.8 m; Style panels concrete posts; Remove an existing fence? yes. These are the recipe's own quantities for those answers - the prices are yours, the supplier's or a quotation's, never a figure typed on a web page.
| Kind | Line | Quantity | How it is worked out |
|---|---|---|---|
| material | Slotted concrete posts | 4 nr 4 x nr - each | 3 bays + 1 |
| material | Fence panels 1.8 m | 3 nr 3 x nr - each | 3 bays |
| material | Concrete gravel boards | 3 nr 3 x nr - each | 3 bays |
| material | Postcrete (20 kg) | 8 bag 8 x bag - 20 kg bags | 4 posts x 2 bags |
| labour | Erect fence | 4.5 hr | 3 bays x 1.5 h |
| labour | Remove existing fence and posts | 0.6 hr | 4 m x 0.15 h/m |
| waste | Old fence (timber, concrete) | 0.2 m3 | 4 m x 0.05 m3/m |
Labour on this example: about 5.1 hours across the roles; at your rates it becomes money.
