How to Sell Used Books in the UK (2026)
You have a shelf — or a cupboard, or a few boxes in the loft — of books you are done with. Some are worth real money, most are not, and the only way to tell has always been to check them one at a time. Here is how selling used books actually works in the UK: what eBay costs, how Royal Mail prices a parcel, and how TroveScore turns a shelf into a sorted list from one photo.
eBay costs you nothing to sell as a private seller
If you are clearing your own shelves, you are a private seller — and since 1 October 2024, eBay UK charges private sellers no final value fee, no per-order fee and no listing fee across nearly every category, including Books, Comics & Magazines. You also get a monthly allowance of free listings (300 at the time of writing); extra listings are 35p each.
The cost moved to the buyer. Every purchase from a UK private seller adds a Buyer Protection fee at checkout — 10p plus 7% of the price up to £20, then 4% up to £300. On a £10 book your buyer pays about £10.80. You never see that money, but it is worth knowing it is there: when you check what similar copies have sold for, a business seller’s listing has no Buyer Protection fee on top, so their price is not quite as high as it looks next to yours.
One note on business sellers: if you buy stock to resell, or your volume starts to look commercial, eBay moves you to a business account, which does pay category fees. Everything here is about selling books you already own.
Postage decides whether a book is worth listing
There is no special “media” postage rate in the UK. Royal Mail prices on size and weight, and one measurement matters more than any other: thickness.
Small Parcel — up to 450mm × 350mm × 160mm, 2kg. 2nd Class from about £4.39.
A typical paperback is 15–20mm thick and posts as a Large Letter for pennies. Wrap it in a padded envelope with too much bubble and you are at 27mm — a Small Parcel, four to five times the cost. On a £4 book, that difference is the whole profit.
- Measure the wrapped parcel, not the book. A snug board wrap keeps a paperback in Large Letter territory; a fat mailer does not.
- Bundles share one postage charge. Three books in one Small Parcel cost the same to send as one — which is what makes selling a series as a bundle work.
Hardbacks and trade paperbacks almost always go as Small Parcels, so they need to be worth clearly more than £4.39 before listing them on their own makes sense.
How TroveScore handles this for you
TroveScore identifies every book in a photo of your shelf and prices them all at once — no typing ISBNs. For a UK user, that means:
- Prices in pounds, from ebay.co.uk. Every scanned book is valued against live UK listings and shown in GBP, so the figure is what the book actually sells for on the site you would sell it on.
- A sell / donate / keep call on each book, using a resale-price threshold set in pounds, so cheap paperbacks are filtered out before you spend twenty minutes on them.
- One-tap listing to ebay.co.uk. Books you choose to sell are listed in GBP from a UK location, with Royal Mail 2nd Class postage and a returns policy already set.
- Country control. TroveScore detects your country automatically; if it gets it wrong, set it in Settings → Country and it stays put.
If you would rather not list them yourself
For books that are not worth an individual listing, UK buyback services take them in bulk and pay the postage: WeBuyBooks (books only, quick payment), Ziffit (scan-and-send, now part of World of Books), and Music Magpie (books alongside DVDs, CDs and tech). They pay per ISBN from a fixed price list, usually well below what eBay would get for anything in demand — you are selling convenience, not value.
That is the split TroveScore is built to make fast: list the handful worth listing, send the rest to a buyback service or a charity shop in one go, instead of checking forty ISBNs by hand to find the four that mattered.
A quick UK workflow
- Scan the shelf with TroveScore — every book identified and priced against ebay.co.uk at once.
- List the ones above the line. The threshold already accounts for what you net after postage.
- Bundle any series. Mid-series books sell poorly alone and share one postage charge.
- Clear the rest in bulk — buyback service or charity shop. Do not spend twenty minutes on a £1.50 paperback that costs £4.39 to post.
