Declutter and Earn: How to Make Money Selling Secondhand in the UK

SYM

The average UK household contains an estimated £2,000–3,000 worth of unused items. Selling secondhand has never been easier — multiple platforms cater to different item types, and successful sellers can clear thousands in a decluttering sweep. Whether it's old electronics, clothes that no longer fit, books, or furniture, here's a platform-by-platform guide to where and how to sell for maximum return.

Clothes, Fashion and Accessories

Vinted is now the UK's dominant platform for secondhand clothing, with 16 million UK users. Seller fees are zero (buyers pay a small service fee), making it the highest-return platform for most clothing items. List everything — items worth as little as £2 sell regularly. Photograph items on a plain background, clean and well-presented. Include measurements, brand, and condition in descriptions. For higher-value items (designer, vintage, branded streetwear), eBay often generates higher bids — the auction format works well for items with genuine demand. ASOS Marketplace is better for genuine vintage and indie brands. Preloved and Depop suit vintage and youth/streetwear respectively.
  • •Vinted: best for everyday clothing, zero seller fees
  • •eBay: best for branded/designer items, auction format maximises high-demand pieces
  • •Depop: youth and streetwear-focused, 10% seller fee
  • •ASOS Marketplace: vintage and independent brands
  • •Photography tip: natural light, plain background, show labels and measurements

Electronics and Tech

Electronics hold value well if in good working order. Trade-in sites (musicMagpie, Decluttr, Zapper, envirofone) offer instant quotes and free postage — convenient but typically 30–40% less than a direct sale. For direct sales, eBay is the strongest platform for most consumer electronics. Facebook Marketplace is excellent for larger items (TVs, monitors, printers) where local collection avoids postage costs and risks. Back Market focuses specifically on refurbished electronics and takes your items on consignment with professional refurbishment — worth it for iPhones and MacBooks. Wipe all personal data before selling — reset to factory settings and de-register iCloud/Google accounts.
  • •Trade-in sites (Decluttr, musicMagpie): convenient but lower return
  • •eBay: best direct-sale return for most electronics
  • •Facebook Marketplace: best for large items (TVs, monitors) — local collection
  • •Back Market: premium for iPhones/MacBooks in good condition
  • •Critical: factory reset and remove all accounts before selling

Books, CDs, DVDs, and Games

Physical media (books, CDs, DVDs, games) has lower individual value but sells in volume. musicMagpie and Zapper are best for bulk selling — you scan barcodes, get an instant quote per item, box them up and post free. Individual prices are low (often 5–50p per book), but a box of 100 items can return £30–80 with zero effort. For gaming specifically — retro games and consoles can be worth significantly more. Valuable console games (PS3 exclusives, certain Nintendo titles, early editions) sell for £15–100+ on eBay. CeX (retail and online) offers cash or credit for games, consoles, and DVDs. Local charity shops also take books and DVDs — no return, but simple and good for the community.
  • •musicMagpie/Zapper: bulk scanning, free postage, good for large collections
  • •eBay: best return for retro games, rare books, collector editions
  • •CeX: cash or credit for games, consoles, tech accessories
  • •Charity shops: simple option for low-value items or large quantities
  • •Check retro game values first — some are worth considerably more than you'd expect

Furniture, Homewares, and Large Items

Furniture and large homewares are almost always better sold locally to avoid logistics. Facebook Marketplace is the dominant platform for furniture in the UK, with active local buyer communities. Gumtree remains popular for larger items. For premium or vintage furniture, Vinterior and 1stDibs cater to buyers willing to pay more for quality. eBay allows collection only listings. Include measurements, condition details, and multiple photos from different angles. Price fairly — buyers need to arrange collection and will factor in effort. Offering free delivery (if you have a van or know someone) can command a 20–30% premium over collection-only pricing.
  • •Facebook Marketplace: most active local buyers for furniture
  • •Gumtree: good for large items, still active in most UK areas
  • •Vinterior/1stDibs: premium vintage and designer furniture
  • •Include: measurements, condition, multiple photos from all angles
  • •Offering delivery: typically commands 20–30% premium

Frequently Asked Questions

Do I need to pay tax on money made selling secondhand?+

Selling personal possessions at a profit is generally subject to Capital Gains Tax (above your annual exempt amount), but selling items for less than you paid (most secondhand selling) creates no taxable gain. If you sell in volume as a business, income tax applies. HMRC has guidance on the distinction.

What are the safest payment methods when selling?+

Bank transfer (BACS/Faster Payments) or PayPal for online sales. Cash on collection for local sales. Avoid cheques, and be cautious of PayPal 'friends and family' payments which have no seller protection.

How do I protect myself against scammers when selling?+

Use the platform's internal messaging system. Don't share personal contact details early. For high-value items, insist on tracked postage and photograph the item before shipping. Be suspicious of overpayment offers or requests to ship internationally to a 'forwarding agent'.

Is there a maximum I can earn before needing to declare it?+

The £1,000 Trading Allowance covers casual occasional selling. Above this, register as self-employed or include the income in a self-assessment return.
