How do I tell if a car-boot seller is a trader or a mum clearing out?

Why does trader versus private seller change my rights?

Citizens Advice's 22 November 2018 marketplace briefing said over 50% of customers did not know they have fewer rights when they buy from a private seller than from a business. The same piece sets out "buyer beware" for a private sale: the seller must not misdescribe the item, but they can omit information. A later Citizens Advice page on returning faulty goods (England) says that if you bought from a business, it does not matter that the item was second-hand — you still have rights if it is not of satisfactory quality, not fit for purpose, or not as described.

Business Companion, written for England and Wales and last reviewed in December 2025, says a genuine non-trader is "largely outside the controls of consumer law", with exceptions. Goods must still match their description under the Sale of Goods Act 1979 (the Consumer Rights Act 2015 is the business-to-consumer statute). A "sold as seen" sign, on their trader section, does not wipe a trader's duties.

This is a process page about who you are buying from. It is not a verdict on whether a used cot, toy or charger is listed on a recall database. Search the model on GOV.UK Product Safety Alerts as a separate job.

What trader tests does Business Companion actually list?

Their car-boot guide says there is no hard and fast rule, then tells the seller to ask themselves the questions below. As a buyer you can ask the same questions out loud. A mum who flinches at "do you do other fields?" is giving you data.

How do I spot a regular trader posing as a clear-out?

1. 1
   Ask the Business Companion questions in plain English "Is this from your house, or do you buy stock in?" "Do you do this every week?" "Have you got the same things at the market?" A genuine mum clearing a loft can usually name the child and the age the item was used. A trader often cannot.
2. 2
   Look at the stock pattern One car of mixed, worn, named-size baby kit leans private. Several sizes of the same unused garment, or toys still in factory wrap with duplicate barcodes, leans bought-in stock — their first test.
3. 3
   Look at the stall furniture A branded gazebo, printed banners, a card reader, numbered receipts and a business name are the Companies Act / Consumer Contracts clues their guide says a trader must be ready to show (identity, address, total price).
4. 4
   Write down what was said Citizens Advice tells marketplace buyers to keep screenshots. At a field sale the equivalent is a phone photo of the stall, the item, and any card receipt. Private-sale disputes turn on the description actually given.

Business Companion says most people who sell at boot sales "probably don't consider themselves to be in trade" even if they sell several times a year. Regularity is still one of their tests. A seller's self-description ("I'm just a mum") is not the legal test.

What rights sit on each side of that line?

• Business seller (trader): Business Companion summarises the Consumer Rights Act 2015 — satisfactory quality, as described, fit for purpose. Within 30 days the consumer may reject and claim a refund; after that, repair or replacement, then a price reduction. A fault in the first six months is assumed to have been there unless the trader proves otherwise. "No refunds" and "sold as seen" signs are called out as misleading about rights.
• Private seller: Their guide says you are largely outside consumer-law controls, but goods must match their description. Citizens Advice's 2018 piece: if a laptop is described as in "excellent working condition" and it is faulty, you can ask for the money back; if that phrase was never used, you may not be able to. Omission is allowed; a false description is not.
• Distance sales extra: Citizens Advice's changing-your-mind page says a 14-day cooling-off period applies when you buy from a business without seeing the item, and does not apply to a private individual. A field sale you attend in person is not a distance contract.

Citizens Advice's 2018 press release also reported more than 13,000 marketplace problems in the previous year and an average loss of £215. That figure is about online marketplaces in 2017–18, not a 2026 car-boot average. Do not treat it as today's field-sale loss rate.

If the stall is a business, which extra product rules sit in the background?

Business Companion reminds traders that goods sold must be safe under the Consumer Protection Act 1987 and the General Product Safety Regulations 2005, and flags toys, electricals, cosmetics, upholstered furniture and nightwear. For toys placed on the Great Britain market, GOV.UK's Toys (Safety) Regulations 2011 guide (updated 24 March 2025) is aimed at businesses. It applies to toys designed or intended for play by children under 14, and sets essential safety requirements and UKCA / CE marking duties.

A cot, Moses basket or car seat is not automatically a "toy" under that guide. Do not use the Toys Regulations as a cot standard. Use them as evidence that a trader stall selling toys has duties a loft-clearing mum does not. Business Companion also tells even private sellers to think twice about nightwear, children's coats with hood cords, and lists prams and pushchairs among "other danger areas".

What should I leave the field with?

1. A working guess against the five Business Companion tests — stock source, regularity, hired help, other venues, income share.
2. The seller's own words about whether this is household clear-out or bought-in stock.
3. Photos of the stall and the item, plus a card receipt if you paid that way.
4. If it is baby kit with a model number, a GOV.UK recall search as a separate job. Trader or mum does not decide what is on the OPSS list.

In shortIn short: quote Business Companion's tests, not a vibe. Regular bought-in stock, other venues and hired help lean trader. A one-off loft clear-out leans private. Citizens Advice is the source for "most people do not know the rights change". Keep the description you were given — that is what a private-sale dispute turns on.
