Waste
What you cannot put in a skip
A mixed domestic skip is not a hole for anything. Hire firms refuse or segregate hazardous, electrical and some bulky items, and they can reject the load if you put the wrong thing in.
Operator lists are not identical. Read the hire firm’s list before you load. If they refuse an item, that is the rule for that skip, even if another firm would take it separately. If you are unsure, ask – do not bury it under timber.
Decide before you book
- List what is actually going in, including the awkward items (sofa, fridge, plasterboard, old paint). For a strip-out, see also kitchen and bathroom job pages.
- Check that list against the table below and against the operator’s own prohibited-items page.
- Book a dedicated collection, an HWRC trip, or a separate skip for anything they will not take in the mixed load.
- If a private firm is taking waste from your house, check they are an upper-tier waste carrier – how to check a waste carrier licence.
Banned or restricted categories
One row per category. “Usual alternative” is the route official guidance points householders at, not a promise that your local tip will take it that day. Check the council first.
| Item | In a mixed skip? | Why | Usual alternative |
|---|---|---|---|
| Asbestos | No | HSE treats asbestos waste as hazardous. It must not be mixed with normal household waste. It goes only to a licensed disposal site, double-wrapped and labelled. | Ask your council via GOV.UK: asbestos in your home. Some HWRCs take a small, pre-booked amount of bonded asbestos. Higher-risk material (sprayed coating, lagging, most insulating board) should be removed by an HSE-licensed contractor. Full page: asbestos and skips. |
| Plasterboard and other gypsum | Often no – or only if segregated | Environment Agency landfill guidance: you must not send gypsum-based waste (for example plasterboard) to a landfill cell that accepts biodegradable waste. Mixed in a general skip, it is hard for the operator to keep that promise. | A dedicated plasterboard skip or bag, or an HWRC plasterboard bay if your council has one. Some firms let you bag it inside a mixed skip. Ask first. Operators disagree. Full page: plasterboard and skips. |
| Fridges, freezers and other electricals (WEEE) | Usually no | Waste electrical and electronic equipment is a separate stream. Fridges and freezers need the gases recovered. Retailers have take-back duties under the WEEE Regulations. | Council bulky collection or HWRC. Or give the old item to the retailer when you buy a new one with the same function – GOV.UK household waste and the WEEE regulations. Full page: fridges, freezers and WEEE. |
| Gas bottles and pressurised cylinders | No | HSE warns that cylinders hidden in metal waste can explode in shredders. “Empty” still usually means residual gas. | Return branded bottles to the supplier. Some civic amenity sites accept LPG cylinders; many do not take medical oxygen or welding gases. Check before you drive. |
| Liquids, paint, solvents, oils and fuels | No | Environment Agency landfill guidance bans liquid waste (except sludge). Wet paint, thinners, oils and fuels are also household hazardous waste. | Use GOV.UK: find a hazardous waste service (England and Wales) or your council’s HWRC chemical bay. Dried-out emulsion is sometimes accepted as ordinary waste – that is a local rule, not a national one. |
| Tyres | Usually no | Landfill guidance bans whole or shredded used tyres, with narrow exceptions (bicycle tyres, and tyres more than 1,400 mm in diameter). | HWRC if your site takes them, or the garage that fitted the new ones. Charges vary by council. This page does not invent one. |
| Soil, rubble and hardcore | Sometimes restricted | Not a legal ban. It is a weight and waste-stream problem. Dense loads hit the lorry’s lift limit. Some firms want inert waste in its own skip; some cap soil at a 4- or 6-yard. | Book a small heavy-waste skip and say it is soil or rubble. Full page: soil, rubble and concrete. A 4-yard or a 6-yard – not an 8-yard of rubble. Two small skips beat one overloaded large one. |
| Clinical and medical waste | No | Landfill guidance bans infectious medical or veterinary waste. Medicines do not belong in a skip or the bin. | Out-of-date or unwanted medicines: take them to a pharmacy. The NHS says do not put them in the bin or flush them. Sharps and other clinical waste: ask your council or GP – pharmacies are not obliged to take them. |
| Upholstered seating that may contain POPs (sofas, armchairs, and similar) | No – do not mix it | Environment Agency guidance (England, updated 29 July 2026): waste upholstered domestic seating containing persistent organic pollutants must not be mixed with other waste in a skip or HWRC bay. If it is mixed, the whole load is treated as POPs waste until the seating can be separated. It must be incinerated, not landfilled. | Council bulky collection or the HWRC’s POPs / bulky-seating bay. Covered items include sofas, sofa beds, armchairs, upholstered dining chairs, stools, bean bags and similar. Mattresses and scatter cushions under 60 cm × 60 cm are outside that guidance – still ask, because operators often refuse mattresses anyway. Full page: sofas, POPs seating and skips. |
| Batteries, fluorescent tubes and other mercury lamps | No | Household hazardous waste. Fluorescent tubes contain mercury. Batteries start fires in compactors. | HWRC battery and lamp banks, or the hazardous-waste finder above. Car batteries are a separate stream at most tips. |
What “the hire company can refuse” means
Two different things get mixed up.
- The law and the regulator. Asbestos, liquid waste, infectious clinical waste, used tyres to landfill, and POPs seating mixed into other waste have official rules. The operator cannot “take it anyway” and stay inside those rules.
- The operator’s list. Soil, a small amount of bagged plasterboard, a mattress, or a single electrical: firms disagree. Their T&Cs win for that booking. They can leave the skip, surcharge you, or reclassify the whole load.
If you add your own waste to a tradesperson’s skip, the duty of care on what you added is yours. If the tradesperson produced the waste as part of the job, that waste is theirs to dispose of – GOV.UK: dispose of household waste.
A working rule
If it is hazardous, electrical, a tyre, a sofa, a gas bottle, a liquid or a sheet of plasterboard, keep it out of the mixed skip until the operator says otherwise. Size the rest of the job on the size guide.
