How to Start Reselling in the UK with £100

£100 is a genuinely workable starting float for UK reselling, but only if you treat it as working capital rather than spending money. The people who fail at this level usually don't fail because £100 is too little. They fail because they spend it on one thing, get it wrong, and have nothing left to try again with.

Split it, don't spend it

Divide the £100 into four buys of roughly £25 rather than one of £100. Four attempts gives you four chances to learn what sells, and one bad call costs you a quarter of your float instead of all of it. At this stage the information is worth more than the margin.

What to buy first

• Things you already understand. If you know trainers, buy trainers. Category knowledge is the only edge you have before you have capital, and it's the difference between spotting a genuine underpriced item and guessing.
• Items that sell in days, not months. A £15 profit that takes two weeks beats a £40 profit that takes four months when you've only got £100 in play. Turnover is what compounds a small float.
• Small and light. Postage eats margin fastest at low price points, and a bulky item can turn a £12 profit into £4.

Costs people forget at this level

1. Postage materials. Bags, tape, labels. Perhaps £10 to £15 to start, and it comes out of your float.
2. Postage itself. Your actual cost, not what you charge the buyer. See our eBay UK fees guide for how fees apply to postage too.
3. Returns. One return on a £25 item can wipe the profit from two successful flips.

When to reinvest and when to stop

Put everything back in for the first few months. A £100 float that turns over twice a month at 25% margin becomes meaningfully larger by the end of the year, but only if you're not drawing from it. Equally, if three or four consecutive flips lose money, stop and work out why before spending more. Persistence is only a virtue when the underlying approach is sound.

The honest expectation

£100 will not replace an income. What it will do is teach you which categories work, how long things actually take to sell, and whether you enjoy the process enough to keep doing it. If you're still going after three months with more than you started with, that's a genuinely good outcome at this level. For the bigger picture, our beginner's guide to retail arbitrage covers the fundamentals.

With a small float, the fee side matters more than usual. Our free fee calculator shows what you keep, and as a private seller that is currently the full sale price.
