The rules about what can go in a skip exist for legitimate reasons - environmental regulations, worker safety, and the requirements of the licensed waste facilities where skip contents are eventually processed. Homeowners are often surprised by what cannot be included, and getting it wrong can result in a skip being refused, an additional charge for hazardous waste handling, or in serious cases, a fine. Understanding the categories before filling the skip avoids these problems.

General waste - the standard content of most domestic skips - covers most household and construction waste. Timber, plasterboard, tiles, bricks, concrete, soil, garden waste, cardboard, plastic, old furniture, old fittings, and general renovation debris all fall within this category. This is what most skips are used for and what the standard pricing assumes. Filling a skip with a mix of these materials is straightforward and needs no particular attention beyond staying within the weight and volume limits.

Hazardous waste is separate cannot go in a general skip, and the list is longer than most people expect. Asbestos is the most obvious - any material suspected of containing asbestos, including old artex, some floor tiles, some pipe lagging, and cement-fibre roof sheets, must be handled by a licensed asbestos disposal service, not put in a skip. Paints and solvents in liquid form, chemicals of any kind, medical waste, and clinical materials all fall into hazardous categories.

Fluorescent tubes and other lamps containing mercury or heavy metals need separate disposal through a WEEE-compliant collector. Ordinary incandescent bulbs are fine in a skip, but strip lights and CFLs are not. Old refrigerators and freezers - particularly older ones containing certain refrigerant gases - are subject to specific regulations and cannot be tipped into general Bournemouth Skips. Some skip companies will accept fridges as a separate line item for a specific handling fee; others will not accept them at all.

Electrical items of any kind are technically WEEE waste and should be separated from general skip contents. In practice, small amounts of electronic waste - a broken kettle, an old radio - often go in with the general contents, but larger items or significant quantities of electronics should be disposed of separately. Batteries of any kind, particularly lithium-ion batteries from power tools or electronics, are a fire hazard in a skip and should be removed to a dedicated battery collection point.

Tyres are a specific category. Most skip companies will not accept car tyres in a general skip because they are difficult to process and are subject to specific disposal rules. Bicycle tyres are usually fine, but four car tyres tossed into a skip will typically result in an additional charge or the skip being refused. Any tyre disposal is best handled through a garage or a dedicated tyre recycling service.

Anything under pressure - gas bottles, oxygen cylinders, aerosol cans that are not completely empty, fire extinguishers - is a hazard in a skip because they can rupture or explode during handling and processing. Aerosols must be empty. Gas cylinders should be returned to the supplier or taken to a licensed disposal facility.

Plasterboard is the material most homeowners are surprised is regulated. Modern plasterboard waste is technically classed as hazardous when mixed with biodegradable waste because it can produce hydrogen sulphide gas in landfill conditions. Some skip companies accept plasterboard in general skips and separate it at the processing yard for an additional handling fee. Others require plasterboard to be in a dedicated skip, which effectively means a small plasterboard skip alongside a general skip for larger jobs.

Waste that looks harmless but is regulated includes some construction materials that are surprisingly problematic. Bonded roof felt and some flooring adhesives can contain traces of hazardous materials. Anything that was manufactured before 2000 and contains any kind of adhesive or waterproofing agent is worth checking before putting into a skip - the age of the material is often a reliable guide to whether it contains anything now regulated as hazardous.

The practical approach for anyone filling a skip is to think about the mix as it goes in. Keep hazardous materials completely separate. If unsure about a specific item, ask the skip company before tossing it in. Any local skip provider will happily talk through what can and cannot go in, and it takes a minute of phone conversation to prevent an issue when the skip is collected. The general rule is that if in doubt, ask - a five-minute phone call costs nothing and avoids potential handling charges or, in the worst case, having to unload a full skip to remove disallowed items.
