The short version
- Typical range: £20 – £90 — see the full breast pump value guide
- What decides your price: condition, and how well you evidence it in photographs
- Cost to sell here: nothing, at any price

Before you photograph it
Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.
- Establish whether your pump is open or closed system. If milk can reach the tubing or the motor, it is open, and it should not be resold for use.
- For a closed-system pump, sterilise everything and note which parts a new owner must replace themselves — valves, membranes, tubing and flanges.
- Test the motor across its suction settings and confirm the power supply is the original one.
The photographs that sell a breast pump
Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.
- The pump unit and all included parts laid out together
- The motor unit with the model number legible
- Any documentation stating it is a closed system, if you have it
- The power supply and tubing, plus any wear or discolouration
Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.
Writing the title and description
Brand, model and system type: “Closed System Double Electric Breast Pump, [Brand] [Model]”. The words closed system belong in the title because informed buyers filter on exactly that. Say clearly which parts are new and which the buyer must replace.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Brand, model, and whether closed system or hospital grade
- Single or double, and whether mains, battery or both
- Which parts are included and which the buyer should replace themselves
- Whether the original power supply and instructions are present
What buyers will actually ask
You will receive the same three messages about a breast pump. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.
Answer definitively, with the model as evidence. This is the whole basis of whether the pump can safely change hands, so an uncertain answer means the sale should not proceed.
List them: valves, membranes, tubing, flanges and bottles are personal parts and a buyer should fit their own. Saying so unprompted marks you as a seller who knows the product.
Test it through the settings and describe what you observe. Motors weaken with use and buyers would rather know than discover.
Pricing it so it actually sells
Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.
The breast pump value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.
What you keep, compared
On a £55 sale — roughly the middle of the range for a breast pump — here is what the commission-charging platforms would take, and what you would keep on each:
| Where you sell it | Fee | You keep |
|---|---|---|
| WishThrift | £0 | £55 |
| Poshmark | −£11 | £44 |
| eBay | −£7 | £48 |
| Mercari | −£6 | £49 |
| Etsy | −£4 | £51 |
Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.
Timing and getting it to the buyer
Steady year round. Closed-system pumps from recognised brands sell quickly; anything that cannot be verified as closed system is slow and should probably not be listed for use at all.
Light and easy to post. Send the motor and hard parts only, and tell the buyer plainly to fit new personal parts before first use.
WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions
Can you sell a used breast pump?
It depends entirely on the type. Closed-system and hospital-grade pumps have a barrier preventing milk reaching the tubing and motor, and are designed to be used by more than one person with new personal parts. Open-system pumps cannot be hygienically decontaminated and should not be resold for use — that is the honest answer even though it costs you the sale.
What is a used breast pump worth?
Typically £20 to £90 for closed-system electric models. See the breast pump value guide for the condition bands.
Which parts should the new owner replace?
Valves, membranes, tubing, flanges and bottles — all the parts that contact milk or skin. Say this in the listing; it costs the buyer little and it is the responsible way to sell one.
