Used fitness trackers in the UK typically sell for £15 to £90 (about $20 to $120). Fitness trackers sell on battery life and whether the strap is standard or proprietary, and both are worth stating before a buyer asks.

Selling a fitness tracker in the UK
Most private sales settle by bank transfer or cash on collection. Faster Payments clear in seconds, which makes a transfer as safe as cash for the seller — wait for it to land before the item leaves your hands.
The UK has the deepest second-hand habit of any of our markets — charity shops, car boot sales and online resale have been mainstream here for decades, so buyers arrive already comfortable with used goods and already know roughly what things are worth.
Royal Mail, Evri and InPost cover the whole country, and InPost lockers mean neither side has to be in for a delivery. Tracked 48 is the usual default for small parcels.
Distance selling rules bind traders, not private sellers, but an item must still be as described and anything sold as working must actually work.
Working out what yours is worth
- Confirm the model still works with a current app
- Charge fully and record real battery days
Getting it ready
- Charge fully and time a realistic period of use with the features you actually run.
- Note the strap width and whether it takes standard bands or a proprietary fitting.

Put in the description
- Brand, model and strap size
- Tested battery life in days with normal use
- Whether the strap is standard width or proprietary
Brand, model and strap: “Fitbit Charge 5, Small Strap, Charger Included”. Model is the search. Say whether the charger is included — almost all are proprietary and a missing one is an expensive nuisance.
Tiny and cheap to post. Include the charger and photograph exactly what goes into the parcel.
It costs nothing to list
There is no listing fee, no selling fee and no commission, so the £90 a buyer pays is the £90 you keep. You and the buyer settle up and arrange the handover between yourselves; WishThrift does not hold the money or ship the item.
Where in the UK
The United Kingdom is a big place and what sells well moves with it. These are the parts of the United Kingdom with their own page for fitness trackers.
Common questions
Where can I sell a fitness tracker in the UK?
List it free on WishThrift and deal with the buyer direct. There is no selling fee, so the whole amount stays with you. Most private sales settle by bank transfer or cash on collection. Faster Payments clear in seconds, which makes a transfer as safe as cash for the seller — wait for it to land before the item leaves your hands.
Can I use my own strap?
Measure the fitting and say whether it takes standard bands. Proprietary strap systems limit the buyer’s options.
Are fitness trackers worth selling?
For modest sums, and only if still app-supported. A tracker whose app has been withdrawn is close to worthless.
Should I unpair it first?
Yes. Remove it from your account and reset it, or the buyer cannot pair it to their own phone.
