The hire of skips is one of the most practical services available for a renovation, clearout, or garden project — a large metal container delivered to your drive, filled at your own pace, and collected when you are done. Straightforward in concept, and usually straightforward in practice. But the hire of skips comes with a set of prohibited items that most people do not read carefully, and putting the wrong material into a hired skip can result in additional charges, refusal to collect, or in serious cases — disposal of hazardous waste — legal liability. Knowing what cannot go in before you fill the skip saves a great deal of trouble.
Key Takeaways
- Skips are for general construction and household waste only — anything classified as hazardous, electrical, or containing regulated materials requires a separate disposal route, regardless of how inconvenient that is.
- Asbestos is the most serious prohibited item — any asbestos-containing material, whether bonded or loose, must be disposed of by a licensed asbestos contractor through a licensed disposal facility. There is no exception.
- Electrical waste (WEEE) cannot go in a skip — televisions, fridges, washing machines, and all other household electricals must be taken to a recycling centre or collected under a WEEE take-back scheme.
- Tyres, batteries, and gas cylinders are universally prohibited — these are refused by every reputable skip hire company and require specific disposal routes.
- Liquids of any kind cannot go in a skip — paint, oil, solvents, cleaning products, and any other liquid must be disposed of separately.
- The skip hirer carries legal responsibility for what goes in — if a skip contains prohibited materials, the hire company may refuse collection, charge additional removal fees, or in serious cases, report the disposal as illegal. You are responsible for the contents.
- When in doubt, ask — reputable skip hire companies will advise on what is and is not acceptable before delivery. It is better to ask than to have a skip returned to your drive uncollected.
Why the Hire of Skips Has Prohibited Items
A skip is not a limitless disposal container. The waste placed into it is taken to a licensed waste transfer station, where it is sorted and processed according to the waste type. Hazardous materials in general waste contaminate the entire load — which then becomes hazardous waste requiring expensive specialist disposal, even if the vast majority of the load was inert rubble or general household waste.
Beyond the cost implications, there are legal requirements. Under the Environmental Protection Act 1990 and the Hazardous Waste Regulations 2005, the disposal of hazardous waste is tightly controlled. The producer of hazardous waste — which is the person putting it in the skip, not the skip hire company — has legal responsibility for ensuring it is disposed of correctly. “I didn’t know it was prohibited” is not a legal defence.
Reputable skip hire companies carry a waste carrier’s licence issued by the Environment Agency, and they are subject to inspection and enforcement. They take prohibited items seriously, both for regulatory and commercial reasons.
What You Cannot Put in a Hired Skip
1. Asbestos
Asbestos is the absolute prohibition in the hire of skips — the one that carries the most serious legal and health consequences. Asbestos-containing materials (ACMs) were widely used in UK buildings until 1999, when the last form of asbestos (chrysotile — white asbestos) was banned for use. Properties built or renovated before 2000 may contain:
- Asbestos cement sheets (in garage roofs, outbuildings, soffits, and gutters)
- Artex textured coatings on ceilings (many pre-1990 Artex formulations contained asbestos)
- Floor tiles (particularly 1960s–1980s thermoplastic or vinyl floor tiles)
- Pipe lagging and duct insulation
- Insulating board in fire doors and ceiling tiles
- Rope seals in boilers and solid fuel appliances
Any asbestos-containing material — whether it appears to be in good condition (bonded asbestos, lower risk) or friable/damaged (loose asbestos, higher risk) — must not be placed in a skip. It must be removed by a licensed contractor and disposed of at a licensed hazardous waste facility. The Health and Safety Executive (HSE) provides guidance on the identification and management of asbestos.
If you are unsure whether a material contains asbestos, treat it as if it does until a professional assessment confirms otherwise.
2. Electrical and Electronic Waste (WEEE)
Waste Electrical and Electronic Equipment (WEEE) is prohibited from skips under the WEEE Regulations 2013. This covers a very wide range of items:
- Televisions, monitors, and computer equipment
- Fridges, freezers, washing machines, dishwashers, and tumble dryers
- Microwaves and other kitchen appliances
- Toasters, kettles, irons, and small household electricals
- Power tools
- Lamps and fluorescent tubes (which also contain mercury)
- Mobile phones, printers, and any other electronic device
White goods (fridges, freezers, washing machines) and fridges in particular are strictly regulated — fridges contain refrigerant gases that are ozone-depleting substances requiring specialist recovery. Taking a fridge to a skip, or leaving one on the kerbside, carries an additional specific prohibition.
Disposal routes for WEEE include: local authority household waste recycling centres (HWRCs), WEEE take-back schemes operated by retailers (when buying a new equivalent appliance, the retailer is required to take back the old one), and registered WEEE treatment facilities.
3. Tyres
Tyres are prohibited from all licensed skips in the UK. They are classified as a controlled waste, and their disposal is regulated because they present significant fire risk, take up disproportionate space in landfill, and can be recycled into useful secondary materials (crumb rubber for playground surfaces and road aggregate, for example).
Disposal options: local authority waste recycling centres (many accept a limited number of tyres per household visit), tyre retailers (who are required to accept tyres removed from vehicles in the course of a tyre change), and specialist tyre recycling services.
4. Gas Cylinders and Pressurised Containers
Gas cylinders — including LPG cylinders (propane and butane camping gas canisters, barbecue cylinders), oxygen and nitrogen cylinders, and fire extinguishers — cannot be placed in skips. A pressurised container in a skip presents a serious fire and explosion risk during compaction at the waste transfer station.
Gas cylinders in good condition can often be returned to the supplier. Empty cylinders can be taken to a scrap metal dealer (who will depressurise and process them safely) or to a specialist waste contractor. Fire extinguishers can be taken to a fire extinguisher servicing company or a household waste recycling centre.
5. Batteries
Batteries — particularly lead-acid car and motorcycle batteries — cannot go in skips. The sulphuric acid in a lead-acid battery is a hazardous liquid, and the lead is a regulated material. Lithium batteries in consumer electronics present a fire risk if damaged or punctured during compaction.
Car and motorcycle batteries: taken to any motor factors, scrap metal dealer, or household waste recycling centre. Small consumer batteries: recycling collection points at supermarkets and retailers accept these.
6. Paints, Solvents, and Liquids
All liquids are prohibited from skips — including paints (oil-based and water-based), varnishes, stains, wood preservatives, adhesives, sealants, engine oil, petrol, diesel, and cleaning solvents. Liquids in a skip can leak through the base of the skip onto the driveway or road surface (causing additional clean-up liability) and contaminate the entire skip load.
Oil-based paint: A household hazardous waste. Many local authority HWRCs accept oil-based paint at dedicated hazardous waste collection points. Some retailers offer paint recycling schemes.
Water-based (emulsion) paint in small quantities: Some skip hire companies will accept dried emulsion paint — that is, paint that has been allowed to harden completely, reducing it from a liquid to a solid. An opened tin of emulsion left with the lid off, or mixed with cat litter or a commercial paint hardener, will solidify and may then be accepted as solid waste. Check with your specific skip hire company.
Engine oil and fuel: Take to a household waste recycling centre or a motor factors / garage that accepts used oil.
7. Medical and Clinical Waste
Medical waste — syringes, needles, used dressings, medications — cannot go in a skip. This is primarily a concern for households where medical waste has accumulated through home care or long-term medication. Clinical waste must be disposed of through a licensed clinical waste contractor or returned to a pharmacist (in the case of unused medication) or through a local authority clinical waste collection service.
8. Plasterboard (Gypsum)
This is a less well-known prohibition but an increasingly enforced one. Plasterboard and gypsum-based board cannot be mixed with other waste types in a skip. When plasterboard waste in landfill comes into contact with organic waste and water, it produces hydrogen sulphide — a toxic gas. As a result, plasterboard requires separate disposal at a dedicated gypsum recycling facility.
Many skip hire companies now offer dedicated plasterboard-only skips or mixed skips with a strict limit on the proportion of plasterboard they will accept. Some will accept plasterboard separately bagged if it is a small quantity. Always confirm the company’s specific policy before putting plasterboard in a general waste skip.
9. Fridges and Freezers
These deserve specific mention in addition to the general WEEE prohibition, because they are the most commonly mishandled large appliance in household waste. The refrigerant gases in fridges and freezers — and the foam insulation in the walls of older models, which may contain CFC or HCFC blowing agents — require degassing by a qualified refrigeration engineer before the appliance can be recycled.
Leaving a fridge on the kerbside or putting it in a skip is specifically illegal under the Ozone Depleting Substances Regulations. Local authority HWRCs accept fridges and freezers and are equipped to handle them correctly.
10. Television Screens (CRT and Flat Panel)
Older cathode ray tube (CRT) televisions contain lead in the glass of the picture tube — a hazardous material that requires controlled disposal. Flat panel screens contain rare earth elements and other materials that require specialist recycling. All screens are WEEE and cannot go in skips.
11. Tar and Tarmac
Old tarmac and tar-bound road materials may contain coal tar, which is classified as a hazardous material under current waste regulations. If you are disposing of driveway material that was laid before approximately 1990, treat it as potentially tar-bound and check with your skip hire company before disposing of it. Coal tar-containing tarmac requires disposal at a licensed hazardous waste facility, not in a general skip.
12. Animal Waste and Soil Contaminated with Animal Waste
Animal waste and soil contaminated with it is classified as a controlled waste and cannot go in a standard skip. If you are clearing a stable, a kennels, or significant quantities of animal-contaminated soil and waste, specialist agricultural or controlled waste disposal is required.
13. Anything That Cannot Be Contained
Skips placed on a public road (which requires a permit from the local highway authority) must not contain loose or lightweight materials that could blow off and create a hazard to other road users. Loose soil, sand, and similar bulk materials that overflow the skip — or lightweight materials like polystyrene, plastic sheeting, and paper that could blow — may not be accepted by some companies or may require a lockable lid or a covering net.
What Happens If Prohibited Items Are Found
If a skip is collected and prohibited materials are discovered at the waste transfer station, the consequences can include:
Additional charges: The skip company may charge the hirer for the additional cost of specialist disposal of the prohibited material, or for the uplift in disposal cost if the entire load has been contaminated.
Refusal to collect: A skip driver who can see obvious prohibited items in the skip on collection may refuse to take it. The skip remains on your property until the items are removed.
Legal liability: In the most serious cases — asbestos, large quantities of hazardous waste — the hirer may face investigation for illegal waste disposal under the Environmental Protection Act 1990.
Before the Hire of Skips: A Quick Checklist
Before your skip is delivered, go through the clearout in your mind and identify anything that falls into the prohibited categories:
- Any materials from a pre-2000 property that might contain asbestos (ceiling texture, floor tiles, garage or outbuilding roofing, pipe lagging)
- Any electrical items that would need to go in
- Any tyres, batteries, or gas cylinders
- Any paints, oils, or liquids
- Significant quantities of plasterboard
- Anything the skip hire company has not explicitly confirmed is acceptable
Call the skip hire company before booking if you are unsure about any specific material. A two-minute phone call is considerably less inconvenient than a skip that arrives and cannot be collected.
The hire of skips remains one of the most efficient and most practical ways to manage the waste from a renovation or clearout. Getting the prohibitions right from the outset is the single step that ensures the process is as straightforward as it should be.
