Timber stud partition (boarded both sides): 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: CLS timber 38 x 89 mm; Plasterboard 12.5 mm, both faces; Acoustic mineral wool 100 mm; Screws, frame fixings, scrim
- Labour: Build stud frame; Board both faces
- Waste: Off-cuts (timber, gypsum)

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 |
|---|---|---|---|
| CLS timber per m2 of partition at 400 mm centres incl. plates and noggins | 3.5 m/m2 | trade practice | assumed |
| Build frame per m2 | 0.5 hr/m2 | trade practice | assumed |
| Board one side per m2 | 0.3 hr/m2 | trade practice | assumed |
A worked example
Answers used: Partition length 4 m; Height 2.4 m; Door openings in it 0 nr; Acoustic insulation in the void? 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 | CLS timber 38 x 89 mm | 36.96 m 16 x length - 2.4 m lengths | 9.6 m2 x 3.5 m/m2 |
| material | Plasterboard 12.5 mm, both faces | 21.12 m2 8 x sheet - 2400 x 1200 sheets | 9.6 m2 x 2 faces |
| material | Acoustic mineral wool 100 mm | 10.08 m2 3 x pack - ~5 m2 per pack | 9.6 m2 |
| material | Screws, frame fixings, scrim | 1 item | one allowance |
| labour | Build stud frame | 4.8 hr | 9.6 m2 x 0.5 h/m2 |
| labour | Board both faces | 5.76 hr | 9.6 m2 x 2 x 0.3 h/m2 |
| waste | Off-cuts (timber, gypsum) | 0.19 m3 | 9.6 m2 x 0.02 m3/m2 |
Labour on this example: about 10.56 hours across the roles; at your rates it becomes money.
Site questions this work raises: Protection and cleanliness, Waste.
Specialists or hire it may need, drafted as enquiries from the job's facts: Electrician (registered).
Skimming the new boards is the plastering recipe; electrics in the wall are the electrician's.
Then what
Price the lines from your crew rates and your material prices (each with its source and date), answer the site questions (parking, skip, welfare, power, water, protection), let JobBosh draft the supplier enquiries you approve, and issue a branded quotation your customer accepts on a secure link.
