What Not to Sell at a Car Boot Sale (UK Rules)

At a UK car boot sale you must not sell counterfeit goods, stolen goods, banned weapons such as flick knives and zombie knives, prescription medicines, alcohol without a licence, or fireworks, and you must not sell knives, tobacco or vapes to under-18s. Many organisers go further and ban live animals, food, second-hand child car seats and anything that looks unsafe. Below is what is illegal, what is risky, and what is simply not worth packing.

This is a plain-English guide, not legal advice. Every organiser sets its own rules too, so if in doubt, ask them before you load the car.

Illegal to sell

• Counterfeit and copied goods. Fake designer clothes, bags, perfume and football shirts, and copied DVDs, CDs and games, break trade mark and copyright law. Trading Standards officers do visit car boot sales.
• Stolen goods. Obvious, but if something looks too good to be true in a buyer's hands, it may be in a seller's too.
• Banned weapons. Flick knives, gravity knives, butterfly knives, knuckledusters, disguised knives and "zombie-style" knives and machetes cannot be sold to anyone.
• Prescription-only medicines, and in practice any medicines. They can only be supplied through a pharmacy.
• Alcohol, unless the sale has a licence to sell it. That includes unopened bottles from the back of the cupboard.
• Fireworks. Selling them needs registration or a licence and is limited to set times of year. They are not for a car boot table.
• Disposable (single-use) vapes, which have been banned from sale in England since June 2025.
• Realistic imitation firearms. Replica guns that could be mistaken for real ones are restricted by law. Leave air weapons and replicas at home too: the rules on selling them are strict, and organisers do not allow them.

Illegal to sell to under-18s

• Knives and bladed items, including kitchen knives, craft knives, penknives with longer blades, axes and razor blades. If you sell them at all, ask for ID and keep them behind the table.
• Tobacco, cigarette papers, vapes and e-liquids.
• Solvents, lighter refills and aerosol paint have age restrictions too.
• Games and films rated 18: do not sell them to children.

Unsafe or risky: think twice

• Second-hand child car seats and cycle or motorbike helmets. You cannot tell whether a seat or helmet has been in an accident, and road safety charities advise against buying them used. Many organisers ban car seats.
• Upholstered furniture, mattresses and cushions without a fire-safety label. Traders must meet the Furniture and Furnishings (Fire) (Safety) Regulations 1988, and many organisers ask every seller to follow them. Keep the label on sofas and armchairs.
• Electrical items that are damaged, have frayed leads, taped plugs or are missing their safety marks. If you do bring electricals, make sure they work and are safe, and say if they are untested.
• Recalled products. Check the government's product safety recalls list for baby equipment, toys, chargers and appliances before you sell them.
• Opened cosmetics and toiletries, and anything past its use-by date.
• Home-made food. Selling food can need registration with the council as a food business. Most car boot sales leave food to their own caterers.
• Live animals. Selling pets as a business needs a licence, and almost every organiser bans animal sales.

Legal, but it will not sell

These are fine to bring, but they usually come home again, so they are not worth the space in the car:

• VHS tapes, cassette tapes (except collectable ones) and old encyclopaedias
• Large old TVs, printers and computer monitors
• Exercise bikes, treadmills and bulky gym kit
• Jigsaws and board games with missing pieces
• Stained, bobbled or damaged clothes
• Single odd items from sets, and chipped glass and china

Charity shops, recycling centres and free-to-collector groups are a better home for most of them. For what does sell, see what sells best at car boot sales, and for the day itself the selling guide and seller checklist. The general car boot sale rules cover pitches, set-up times and trader rules.

Frequently asked questions

What are you not allowed to sell at a car boot sale?

Counterfeit and stolen goods, banned weapons such as flick knives and zombie knives, prescription medicines, alcohol without a licence, fireworks and disposable vapes. Knives, tobacco and vapes must not be sold to under-18s. Organisers often also ban live animals, food and child car seats.

Can you sell knives at a car boot sale?

Ordinary kitchen and tool knives can be sold to adults, but it is an offence to sell a knife or bladed item to anyone under 18, and banned types such as flick knives and zombie knives cannot be sold at all. Many organisers ban knives entirely, so check first.

Can I sell electrical items at a car boot sale?

Yes, if they are safe. Check leads and plugs, make sure the item works, and tell buyers if it is untested. Do not sell anything damaged or recalled.

Can I sell second-hand furniture at a car boot sale?

Yes. Upholstered furniture such as sofas and armchairs should keep its fire-safety label; traders must meet the fire safety regulations, and many organisers expect every seller to. Wooden and metal furniture has no such rule.

Can you sell food at a car boot sale?

Usually not. Selling food can mean registering as a food business with the council, and most organisers only allow their own caterers. Ask the organiser before you bring any.
