Ground Screw Price Calculator
Get an instant estimate for domestic and trade projects. Formal quote confirmed within 1 working day.
1. Are you a trade buyer?
Trade pricing shows both ex and inc VAT. Domestic pricing is shown inc VAT.
2. Layout
Standard calculates the screw count from your dimensions. Bespoke lets you enter the number of screws directly — for non-rectangular layouts or where you already know the count.
Enter the overall footprint of your garden room in metres.
3. Screw Length
Select the screw length that best matches your build and ground conditions. If you're unsure, give us a call and we'll advise.
4. Select Base Type
Your base frame type determines the maximum recommended screw spacing. Not sure? Choose "I'm not sure" — we'll use a standard 1.2m × 1.2m spacing that works for most projects.
What's the difference between base types?
4"×2" — Traditional timber joists (47×100mm). Max spacing: 1.2m × 1.2m.
5"×2" — Heavier timber joists (47×125mm). Max spacing: 1.5m × 1.5m.
6"×2" — Heavy-duty joists (47×150mm). Max spacing: 1.8m × 1.8m.
If you're unsure, your garden room supplier will know this — or we can advise when we follow up.
5. Max Screw Spacing
Auto-filled from your base type above. Edit here if you need a custom spacing.
