Choosing the right skip waste type saves you money, prevents collection refusals, and keeps your project moving forward. We’ve seen hundreds of skip orders rejected because someone mixed plasterboard with general waste or tried to dispose of prohibited items.
This guide walks you through the different types of skips available, what waste types you can dispose of in each one, and how to avoid the common mistakes that cost time and money.
Why Skip Waste Types Matter
Understanding the types of waste skips helps you choose the right solution for your project. Different waste types incur different disposal costs. Fully recyclable materials like wood or metal typically cost less than mixed general waste. When you segregate your waste properly, you reduce landfill tax charges and improve your environmental impact.
The UK currently charges £126.15 per tonne in landfill tax (as of April 2025). Construction and demolition waste alone generated 67.8 million tonnes in 2018, making up 62% of total UK waste. Proper skip selection directly affects your bottom line.
Understanding Different Waste Types for Skip Hire
General Waste Skips
General waste skips accept the widest range of materials. You can dispose of metals, plastics, wood, bricks, tiles, concrete, ceramics, soil, and hardcore in these skips. However, plasterboard must be kept separate and requires specialist disposal.
The 8 cubic yard skip remains the most popular choice for both domestic and commercial projects. These “builder’s skips” hold approximately 80 bin bags of waste.
What you can put in:
- Household waste and packaging
- Garden waste
- Building materials (mixed)
- Furniture (without upholstery containing POPs)
- Carpets and flooring
- Plastics and metals
General waste skips work well when you have mixed materials from renovation projects or house clearances. The flexibility comes at a slightly higher cost compared to other types of skips designed for segregated waste.
Inert Waste Skips
Inert waste skips accept materials that don’t decompose or change chemically. These skips cost less because the waste is easier to process and often gets recycled into aggregate for construction projects.
What qualifies as inert waste:
- Bricks and blocks
- Concrete and cement
- Tiles and ceramics
- Soil and subsoil
- Hardcore and rubble
- Stones and rocks
Construction sites benefit most from inert waste skips. When you’re demolishing walls, digging foundations, or removing old paving, an inert skip keeps costs down and recycling rates up.
Important: Don’t mix wood, metal, or plastic with inert waste. Even small amounts of contamination can result in reclassification and additional charges.
Plasterboard Waste
Plasterboard cannot be disposed of in standard skips because it releases hydrogen sulphide gas when mixed with biodegradable waste in landfills. This gas is harmful to human health and the environment.
UK regulations mandate segregated plasterboard disposal. Plasterboard must be kept completely separate from other waste types and requires specialist collection and disposal services.
Plasterboard materials requiring separate disposal:
- Plasterboard sheets
- Drywall
- Gypsum products
- Ceiling tiles (non-asbestos)
Renovation projects and interior fit-outs generate substantial plasterboard waste. If you need to dispose of plasterboard, contact us to arrange appropriate specialist waste collection services that ensure legal compliance and proper recycling.
Wood and Recyclable Materials
Wood waste can be accepted in skips for recycling into chipboard, biomass fuel, or animal bedding. Segregating wood and other recyclable materials reduces disposal costs because they’re valuable recyclable materials.
Acceptable wood waste:
- Untreated timber
- Treated timber (some restrictions apply)
- Wooden pallets
- Floorboards
- Fence panels
- Furniture frames (without upholstery)
Construction businesses can reduce onsite waste by up to 15% through detailed site waste management plans. Proper waste segregation forms a key part of this strategy.
What You Cannot Put in Any Skip
UK regulations strictly prohibit certain items from all skip types. These restrictions protect the environment, waste handlers, and the general public.
Prohibited items include:
- Plasterboard (requires specialist disposal)
- Electrical appliances (covered by WEEE Directive)
- Tyres (fire risk and non-biodegradable)
- Asbestos (serious health hazard)
- Batteries (all types)
- Hazardous chemicals and paints
- Medical waste
- Upholstered furniture containing POPs (since January 2023)
- Fluorescent tubes and light bulbs
Violating these restrictions results in extra charges, refusal of collection, or legal penalties. Between April 2023 and March 2024, England recorded 1.1 million fly-tipping incidents—one every 27 seconds. Proper skip hire and legal waste disposal combat this growing problem.

Skip Sizes
Figuring out the right skip size can be annoying. Go too small and you’re cramming things in like you’re packing for a holiday. Go too big and you end up paying for half-empty space. Most of the time, you just want a simple list so you can crack on.
Skip sizes in the UK stick to yard measurements, and these are the ones you’ll see most often:
- 4 yard skip
- 6 yard skip
- 8 yard skip
- 10 yard skip
- 12 yard skip
- 14 yard skip
- 20 yard skip
- 35 yard skip
- 40 yard skip
These cover pretty much every job you’ll run into. Small garden clear-outs, kitchen rip-outs, big building work, all of it. And honestly, if you’re torn between two sizes, go for the bigger one. Saves you from ordering a second skip later.
Choosing the Right Skip Type for Your Project
Start by identifying your main waste stream. A building site with mostly rubble benefits from inert waste disposal. A house clearance with mixed materials requires a general waste skip.
Ask yourself:
- What’s the primary material you’re disposing of?
- Can you segregate different waste types?
- Do you have any prohibited items that need separate disposal?
- What’s your budget for waste disposal?
Segregating waste saves money and improves recycling rates. When you separate inert waste from general waste, you reduce landfill tax charges and support environmental targets.
Understanding the different types of skips available helps you make informed decisions. Skip sizes in the UK still use imperial measurements. Sizes range from 2 cubic yards (mini skips holding 20-30 bin bags) to 40 cubic yard roll-on/roll-off skips for large industrial projects. A useful rule: you can fit a maximum of 10 bin bags per cubic yard.

Getting Your Skip Hire Right
Proper skip selection starts with understanding your waste. Identify the materials you need to dispose of, check they’re permitted in skips, and order the appropriate size for your project.
When you segregate waste effectively, you reduce costs, improve recycling rates, and keep your project running smoothly. We offer skips ranging from 4 to 40 cubic yards, ensuring you get reliable collection and proper disposal for your specific needs.
