Selling things you already own is one of the simplest ways to raise extra money without committing to a new job or business. It also reduces clutter, but the value depends on what you have and what buyers are willing to pay.
Start with obvious unused items
Look for clothing in good condition, children’s items that are no longer needed, electronics, tools, furniture, collectibles and household products that still have useful resale value.
Research sold prices, not hopeful asking prices
Where a marketplace provides completed-sale information, use it to understand what comparable items actually sell for. An unsold listing at a high price is not evidence of value.
Choose the platform to fit the item
Different marketplaces suit different products, values and collection requirements. Consider seller fees, postage, payment protection and the amount of effort required.
Use accurate descriptions
Photograph condition clearly and disclose faults. Accurate listings reduce disputes and wasted time.
Calculate your net proceeds
Deduct marketplace fees, packaging, postage and other selling costs before deciding whether an item is worth listing.
Stay alert to scams
Keep communication and payment within the marketplace where appropriate, and be cautious about unexpected links, overpayments or requests to move outside normal payment processes.
If you use the proceeds to strengthen household finances, consider directing some toward an emergency fund or another priority in your budget.
A practical guide to sorting, pricing, listing and handing over unwanted possessions safely—while understanding the time, fees and possible tax questions.
Selling something you already own can bring in useful money, but it is not guaranteed income. The final amount depends on condition, demand, fees and the time involved. Begin with a small batch of items you no longer use, and do not count expected sale money toward a bill until the buyer has paid and the transaction is complete.
Choose items that are worth the effort
Start with things that are clean, complete and easy to describe: children’s clothing bundles, toys with all parts, small appliances, tools, books, games, furniture or electronics. Check that the item belongs to you and that you are allowed to sell it. Do not sell recalled, unsafe or counterfeit goods. For children’s equipment, electrical products and anything safety-related, check current product safety notices and guidance before listing.
Sort items into four groups: sell, give away, recycle and keep. Selling every small item can take more time than it is worth. A bundle can make low-value clothing easier to move, while a higher-value item may deserve its own listing. If an item is damaged, decide whether a clear description still makes a sale sensible; otherwise recycle or dispose of it responsibly.
Research realistic prices
Search completed or sold listings for the same model, size, condition and included accessories where the platform provides them. Asking prices show what sellers hope to receive; completed sales give a better clue about what buyers paid. Compare several listings and note how long they were available if that information is shown. The price may vary by season, local demand and postage cost.
Decide your minimum acceptable amount before messages arrive. Include platform fees, payment fees, packaging, postage, travel to a collection point and the value of your time. For example, if an item might sell for £20 but fees and postage would take £7, your net proceeds are much closer to £13. These are example figures only; calculate the current costs for your platform and item.
Pick the selling route that fits the item
Online marketplaces can reach more buyers but may charge fees and require packing, postage or dispute handling. Local collection avoids postage but means arranging a safe handover and may attract no-shows. Charity shops or local reuse groups may be simpler for modest items, while a car boot sale can shift many low-value things at once but involves a stall fee and travel. Compare the likely net money and effort, not just the possible headline price.
Read the platform’s current rules for prohibited items, payment, seller protection, postage deadlines and returns. Keep messages and payment within the platform where required. A buyer asking to switch immediately to a separate messaging or payment service may remove protections and make it harder to resolve a dispute.
Prepare an honest listing
Clean the item safely and check that it works, where relevant. Photograph it in good light from several angles, including labels, model numbers, accessories and flaws. Avoid showing your address, children’s faces, school logos, personal documents or anything else that identifies your family. Use your own accurate photos and do not reuse a manufacturer’s image in a misleading way.
Write a title that names the item, size or model and condition. State what is included, what is missing, known faults, measurements and whether collection or postage is available. If you do not know something, say so rather than guessing. Honest descriptions reduce wasted questions and lower the risk of disagreement after the sale.
Set a safe collection and payment plan
For a local collection, agree a public or otherwise safe arrangement appropriate to the item and your circumstances. You do not have to invite a stranger into your home; if an item is too large to move, consider having another adult present or using a trusted delivery option. Share the plan with someone you trust. Do not hand over the item based on a screenshot or email that claims payment has been made—check the payment in your own account or the platform’s transaction record.
Be wary of overpayment stories, links to “release” funds, requests for a verification code, fake courier arrangements and buyers who pressure you to act immediately. Never share a one-time bank or platform security code. Open the marketplace app or website directly instead of following unexpected payment links. The National Cyber Security Centre has guidance on staying safe when shopping online; its advice is useful when dealing with suspicious online messages too.
For postage, package the item securely, use the service agreed through the platform and keep proof of postage and tracking. Photograph the item and packaging before dispatch for your own records. Do not mark an item as sent until it has actually been handed to the carrier.
Keep a simple record of money and costs
Write down the item, date listed, final sale amount, platform charges, postage or packaging and net money received. This helps you see which selling route is worthwhile and provides a clear record if you need to query a transaction. Remove the listing promptly when an item sells elsewhere so you do not accept payment twice.
Money from selling your own personal possessions is often treated differently from running a business or buying goods to resell. HMRC explains that personal possessions are items you owned for your own use, and that selling them is unlikely to mean Income Tax is due in many ordinary clear-out situations. However, tax can depend on what the item is, whether you made a gain, its value and whether your activity is actually trading. There are separate rules for some high-value possessions and for goods bought or made to sell. Read HMRC’s current online platform income guidance and use its checker if your circumstances are more than a straightforward clear-out. Platform reporting does not by itself mean tax is owed.
Use the money according to a plan
Before selling, decide where the proceeds will go: an overdue essential bill, a replacement item, a small emergency buffer or another priority in your household budget. If the money is shared with another owner, agree that first. For family items, involve the person whose belongings they are where appropriate. A sale can be useful, but it should not be treated as a reliable answer to a recurring shortfall.
If a listing gets no interest, review the photos, title, price and collection options once. If the likely return is too small, remove it and donate or recycle instead of spending weeks relisting. When money pressure is ongoing, review the family budget, check possible support and seek free debt advice if needed. Selling possessions is one option, not a measure of effort or worth.
A quick listing checklist
- Confirm ownership, condition and whether the item is safe and legal to sell.
- Check completed prices, current platform rules and all likely fees.
- Photograph the actual item and describe faults clearly.
- Choose a payment, postage or collection method you can verify safely.
- Record net proceeds and remove the listing when it is sold.
- Use HMRC’s current guidance if you are buying to resell or unsure about tax.

Handle disagreements and returns calmly
Read the platform’s dispute process before a problem arises. If a buyer says an item was not as described, keep the conversation factual, refer to your listing and photos, and use the platform’s resolution process. Do not send extra money or share account codes to “unlock” a refund. If you are selling as a trader rather than occasionally clearing personal belongings, different consumer responsibilities may apply; check current GOV.UK or Citizens Advice information before advertising.
Set a time limit for your own effort: for example, list a batch for a few weeks, then review. Re-photograph or adjust a realistic price once if needed. If the item still does not sell, choose a donation or reuse route and reclaim the space. A completed clear-out can be worthwhile even when it does not produce much cash.
