What it is
You buy used trailers from private sellers, farms and auctions, check and tidy them, then resell them through online adverts. Viewings are by appointment at a rented yard, a farm unit or space you already have.
Your first three steps
- Study local used trailer adverts for a few weeks to learn typical prices for the types you want to specialise in
- Arrange somewhere safe and legal to store a few trailers and show them to buyers, and check the terms of your lease or tenancy
- Buy one or two well-priced trailers, fix any small faults, then advertise them with clear photos and full details
Who pays
Hobbyists, tradespeople, horse owners, smallholders and small businesses wanting a trailer without paying new prices.
How it makes money
You earn the margin between buying and selling prices, plus small extras such as new tyres, lights, spare wheels or delivery.
Skills that help
- Spotting faults and judging condition
- Negotiating when buying and selling
- Writing honest adverts with good photos
- Basic trailer maintenance
Watch out for
- Check ownership: make sure the seller can prove the trailer is theirs and that it is not stolen or on finance
- Consumer law applies to sales to individuals, so check your duties on description, quality and refunds
- Check that brakes, lights, tyres, couplings and plates are roadworthy before selling, and that the trailer is legal for its intended use
- Stock insurance, public liability insurance and theft cover for stored trailers are worth checking
- Check whether your home, farm or yard allows trade visits, and whether you need planning permission or landlord consent
- Tie up cash in stock, as a trailer can take weeks or months to sell

Questions people ask
How much does it cost to start selling used trailers in the UK?
Startup costs are typically around £1,500 to £8,000, depending on how many trailers you buy, your yard or storage space and your advertising. These are estimates, and stock ties up cash because a trailer can take weeks or months to sell.
How much can a used trailer dealer make?
Monthly revenue is typically around £1,000 to £8,000, depending on how many trailers you sell and the type you stock. That is revenue rather than profit, so allow for purchase prices, repairs, advertising and storage.
What should I check before reselling used trailers?
Check the seller can prove ownership and the trailer is not stolen or on finance. Check consumer law duties on description, quality and refunds, and that brakes, lights, tyres, couplings and plates are roadworthy. Also check stock and public liability insurance.
