Top-up the Difference
If values don't match, simply pay the difference. More matches. More choices. More value.
One transaction instead of four
- 1. You sell your item
- 2. You receive cash
- 3. You buy what you need
- 4. You receive it
You sell one thing to get cash, then use cash to get another thing.
Value friction ≈ £200 on a £1,000 item · Time: several days to weeks
You exchange directly. Top up if values differ.
Marcha removes the sell-first step.
Value gap → top-up · Potentially same-day once matched
The goal: Marcha value — not run a mini resale business.

Where Marcha works
Marcha is a UK exchange marketplace, starting in London. You choose your general area or postcode district and a distance of 1 to 50 miles, and see listings within that radius on a map, as swipeable cards, or as a list.
How matching works
You say what you have and what you want. Marcha looks for listings whose owners want something like yours, and shows how closely each one fits. A match is a suggestion — nothing happens until both members show interest.
Negotiated top-ups
If the two items are worth different amounts, you can propose a straight exchange or a top-up paid by either side. Either member can counter or decline, and only the newest proposal can be accepted. A Marcha is agreed only when both accept the same proposal. Suggested values are estimates, not guarantees, and agreeing a top-up does not take any payment.
Privacy
Other members see your first name, general area, ratings and completed Marchas. Listings show an approximate area only — never your full postcode or address. Phone numbers and emails stay private unless you both choose to swap them. Chats are private between the two members.
Arranging the exchange
Once a Marcha is agreed, both members agree the meet-up details in chat and can add them to their calendar. Items are exchanged in person between members. Marcha does not hold money and provides no escrow, insurance, couriers or authenticity guarantees.
What you can't list
Live animals cannot be listed or exchanged on Marcha. Pet products such as beds, carriers, cages and toys are fine.
