How We Calculate This
This guide recommends the right skip size based on either your estimated waste volume or your project type. We match your requirements to the smallest skip that will comfortably hold your waste.
Skip sizes available in the UK
- Mini (2-yard): 1.5 m³ capacity, ~30 bin bags
- Midi (4-yard): 3.0 m³ capacity, ~45 bin bags
- Builder's (6-yard): 4.6 m³ capacity, ~65 bin bags
- Large Builder's (8-yard): 6.1 m³ capacity, ~85 bin bags
- Maxi (12-yard): 9.2 m³ capacity, ~130 bin bags (light/bulky waste only — not soil or rubble)
- Roll-on-Roll-off (16-yard): 12.2 m³ capacity
Capacity in m³ is the cubic-yard size × 0.765 (1 cubic yard ≈ 0.76 m³ ≈ 10 bin bags); bin-bag counts are approximate and vary by company. Names follow common UK skip-hire usage — the 8-yard is the “large builder's skip” and the 12-yard the “maxi skip”.
Project type estimates
When you select a project type, we recommend a skip based on typical waste volumes for that type of job. These are industry averages — your actual waste may vary depending on the scope of work. When in doubt, go one size up to avoid overfilling (which is illegal and the skip company will refuse to collect).
Frequently Asked Questions
The 6-yard builder's skip is the most commonly hired skip in the UK. It holds approximately 4.6 cubic metres (around 65 bin bags) and is suitable for most single-room renovations, kitchen refits, and medium-sized clearance jobs. It is large enough to be useful but small enough to fit on most driveways.
Yes, if your skip is placed on a public road, pavement, or highway, you will need a skip permit from your local council. Costs vary by council (typically £20-£65) and the permit is usually valid for 2-4 weeks. If the skip is on your private driveway or land, no permit is needed. Your skip hire company can usually arrange the permit for you.
You cannot put hazardous waste in a skip, including asbestos, batteries, gas bottles, tyres, paint tins (unless empty and dry), electrical equipment (WEEE), fridges/freezers, medical waste, or plasterboard (which must be separated). Some skip companies also charge extra for mattresses. Always check with your skip hire company before loading.
Standard hire periods are commonly around 7-14 days, but this varies by company — always check your booking. After the included period you may be charged a daily or weekly extension fee (often in the region of £5-£15 per day, depending on the firm and area). If you need the skip for longer, arrange an extended hire upfront, as this is usually cheaper than paying daily overage charges. These figures are indicative industry conventions, not fixed rates.
A single larger skip is almost always cheaper than two smaller ones. For example, one 8-yard large builder's skip (6.1 m³) usually works out cheaper than hiring two 4-yard midi skips (6.0 m³ combined), because the delivery and collection fees are charged per skip and are the biggest part of the cost. The exact saving varies by company and area, so always compare quotes.
