Sell phone privately vs buyback site: which pays more in the UK?

When it's time to get rid of an old phone, you have two main options: sell it yourself through a marketplace like eBay, Facebook Marketplace, or Gumtree, or hand it to a buyback service that pays you directly. Both routes have real merits and real drawbacks. This guide lays them out honestly so you can choose based on your phone, your situation, and how much your time is worth.

Private sale: how it works and what to expect

Selling privately means listing your phone yourself, fielding enquiries, negotiating on price, arranging payment, and posting the device or meeting a buyer in person. The main draw is the headline price: for a well-maintained, in-demand handset like a recent iPhone or Samsung flagship, a private listing can attract more than any buyback service will offer.

The catches are real, though.

Fees reduce what you actually keep

eBay charges a selling fee (currently around 12.8% of the sale price including postage for most categories, plus a fixed charge per listing). PayPal fees no longer apply for domestic transfers in the UK, but many sellers still lose 5 to 13% of the headline figure before they see a penny. On a phone listed at £300, that can mean £40 or more gone in fees alone.

Time and effort add up

Writing a listing, taking photos, answering the same questions repeatedly, waiting for bids to close, re-listing when it sells and the buyer disappears. A typical eBay sale for a phone takes several hours of active effort spread over days or weeks. Facebook Marketplace and Gumtree are faster but messier: low-ball offers, time-wasters, and buyers who ghost you after agreeing a price are common.

Scams and chargebacks are a real risk

Phone fraud on peer-to-peer platforms is well-documented. Fake payment confirmations, buyers claiming the phone never arrived, eBay claims opened weeks after a sale, and "overpayment" cheque scams all target private sellers. eBay's buyer protection policies tend to favour the buyer, which means a dishonest buyer can sometimes initiate a return even after using the phone for weeks.

In-person sales carry their own risks

Meeting a stranger to hand over an expensive item has obvious safety considerations. Counterfeit notes are occasionally used. Buyers may attempt to swap devices during inspection or claim a fault on the spot to force a lower price.

Postage and transit risk

If you post the phone yourself, you are responsible for packing it securely, buying tracked postage, and dealing with any transit damage or loss. Standard Royal Mail services do not cover the full value of a smartphone. Specialist postal insurance adds cost and admin.

Buyback service: how it works and what to expect

A buyback service gives you a quote, you post the phone using a prepaid label, the company inspects it, and pays you. The whole process typically takes two to three days from posting. See exactly how it works at Cash My Tech if you want the step-by-step.

The headline price is usually lower than what you could get from a private sale for a pristine flagship. That gap is smaller than it looks once you account for fees and time, but it exists and it is worth acknowledging.

No fees, no negotiations

The price you are quoted is what you receive. No platform fees, no commission, no PayPal deductions. What you see is what arrives in your bank account.

Free postage and transit cover

Reputable buyback services provide a prepaid Royal Mail tracked label. The device is covered in transit, and you have proof of sending. You do not need to buy packaging or insurance separately.

Accepts broken and damaged phones

Private buyers on eBay almost always want a working phone in reasonable condition. Buyback services buy phones in any condition, including cracked screens, water damage, and faulty devices. If your phone is broken, private sale is rarely a realistic option.

No scams, no chargebacks, no strangers

You are selling to a business with legal obligations. There is no risk of fake payment, no eBay claim thirty days later, and no meeting in a car park. For most people, that peace of mind is worth the difference in headline price.

Same-day payment

Services like Cash My Tech pay by same-day bank transfer for devices inspected before 2pm. If you need money quickly, a buyback beats waiting for an eBay listing to close and funds to clear.

Which should you choose?

Go private if:

• Your phone is a current-generation flagship (iPhone 15 or 16 series, Samsung S24 or S25) in excellent or mint condition
• You have the time to manage a listing properly
• You are comfortable absorbing the fees and the small risk of buyer disputes
• Maximising the final pound figure is more important than speed or simplicity

Use a buyback service if:

• Your phone is more than two years old, or mid-range rather than a flagship
• The screen is cracked, the phone has faults, or it won't turn on
• You need payment quickly, ideally the same day you post
• You want to avoid fees, negotiations, and the risk of scams
• You want someone else to handle the certified data wipe

For most people selling a phone that is more than eighteen months old, the maths tend to favour a buyback once fees and time are factored in. For a pristine iPhone 16 Pro, a well-managed eBay listing might genuinely net more after fees, particularly if you are not in a rush.

If you are unsure whether your phone qualifies as "in-demand enough" to justify the private sale effort, check current completed listings on eBay (filter by sold items) and compare that net figure (minus around 13%) against a buyback quote. That comparison takes about five minutes and removes the guesswork.

A note on data security

Whichever route you take, remove your accounts and do a factory reset before handing the phone over. With a private sale, that is the end of your data protection: once the buyer has the phone, there is nothing further you can control. A buyback service like Cash My Tech performs a certified data wipe after receiving the device, in line with UK GDPR and the WEEE Regulations 2013. That is an extra layer of assurance, not a replacement for doing your own reset first.
