Whether you’re clearing a house, stripping out a shop unit, tackling a garden overhaul or sorting out a renovation, a skip keeps everything tidy and makes the whole job feel more manageable. But while skips can take a huge range of everyday waste, you can’t just throw everything straight in. And some items are restricted for very good reasons.
At PP O’Connor Skip Hire, we want your hire to go smoothly from drop-off to collection. That’s why we’ve put together this clear, practical guide to what can’t go in a skip, why these rules exist, and what to do with restricted waste instead.
Why Are Certain Items Not Allowed in a Skip?
A quick one to start: restricted items aren’t banned to make life difficult. They’re restricted because:
- They can be hazardous to people
- They require specialised recycling
- They can damage sorting equipment
- They’re controlled by UK waste regulations
- They risk contaminating recyclable materials
Putting the wrong thing in a skip can mean delays, extra charges, or the skip not being collected at all. So, it’s always worth checking.
What You Can’t Put in a Skip (And What To Do Instead)
Below is a simple breakdown of the main types of restricted waste and how to dispose of them safely.
Electrical Items (WEEE Waste)
Examples: TVs, microwaves, kettles, hairdryers, computers, fridges, freezers, cables.
These fall under WEEE regulations because electrical items must be dismantled, stripped, and recycled at authorised facilities. Many contain metals, components or chemicals that can’t go into general waste streams.
Why they’re restricted
Some electricals also classify as POP waste (Persistent Organic Pollutants), materials that don’t break down naturally and require controlled handling.
What to do instead:
- Use your local council’s electrical recycling service
- Take them to a registered household waste recycling centre
- Arrange a bulky item collection if they’re large
- For businesses, use a licensed WEEE disposal contractor
Tyres
Tyres can’t go into a skip because they must be processed using specialist shredding and recycling equipment.
Why they’re restricted:
Tyres contain materials that require controlled treatment. Landfill regulations also classify tyres as problematic waste.
What to do instead:
- Take waste tyres to a garage or tyre centre (they’ll usually recycle them)
- Use a licensed tyre recycling company
- Ask your mechanic. Most offer disposal with replacements
Paints, Liquids and Solvents
Examples: Paint, varnish, thinners, fuel, motor oil, adhesives, cleaning chemicals.
Empty and fully dried tins are fine, but liquids are not.
Why they’re restricted:
These liquids are classed as hazardous waste because they can leak, contaminate other waste, and risk chemical reactions during handling.
What to do instead:
- Allow small amounts of paint to dry out completely before disposal
- Use local hazardous waste collection services
- For businesses, use a licensed hazardous waste contractor
Asbestos
Asbestos needs highly specialised handling and protective equipment.
Why it’s restricted:
Even minimal disturbance creates airborne fibres that are dangerous to inhale.
What to do instead:
- Hire an asbestos removal specialist
- Never attempt to dispose of asbestos yourself
Medical & Clinical Waste
Examples: Needles, sharps, medicines, bandages, PPE, sanitary waste.
Why it’s restricted:
Clinical waste can carry biological risks and must be handled under strict medical waste rules.
What to do instead:
- Contact a licensed clinical waste service
- Return unused medication to a pharmacy
Gas Cylinders and Pressurised Containers
Examples: Butane bottles, oxygen tanks, BBQ gas bottles, aerosols.
Why they’re restricted:
They remain dangerous even when “empty” and can explode under pressure during compacting.
What to do instead:
- Return cylinders to the supplier
- Use authorised gas bottle recycling schemes
Plasterboard (In Large Quantities)
Small amounts are sometimes acceptable if separated in its own bag, but plasterboard cannot be mixed with general waste.
Why it’s restricted:
When mixed with biodegradable waste, plasterboard can create hazardous gases.
What to do instead:
- Bag plasterboard separately
- Use a dedicated plasterboard recycling service
Mattresses
This is one that catches people out.
Some skip companies take mattresses, others do not. And some charge extra because mattresses must be broken down manually.
Why they’re restricted:
Springs, foams and textiles all need separating before recycling.
What to do instead:
- Ask us in advance. We’ll confirm if your skip size and waste type is suitable
- Use a local bulky waste collection
- Take to a household recycling centre
Batteries
All batteries, including car batteries, household batteries, and lithium packs, are restricted.
Why they’re restricted:
They contain chemicals and heavy metals that require specialist recycling.
What to do instead:
- Use supermarket battery drop-off points
- Take car batteries to a recycling centre
Garden Waste (Sometimes)
Standard green waste like leaves, branches and grass is allowed. But certain garden materials are restricted.
Restricted garden waste items include:
- Soil containing chemicals
- Treated timber
- Japanese knotweed (a controlled plant)
- Large tree roots that won’t fit
What to do instead:
- Speak to us first. We’ll guide you based on the skip size and waste type
- Use a green waste facility for large loads
- Arrange specialist disposal for invasive plants
So… What CanGo in a Skip?
Most everyday waste is absolutely fine:
- Furniture
- Packaging
- Plastics
- Wood
- Soil (clean)
- Rubble
- Bricks
- Metals
- Carpets
- Garden waste (standard green waste)
When in doubt, just ask. We’ll point you in the right direction.
