InPost lockers for standard items, Royal Mail for heavy items

Last updated 30 September 2026

Nivaii ships within the UK. Standard items go to an InPost parcel locker. Items over 15 kg go by Royal Mail. The listing decides which method applies, and the purchase is completed in the Nivaii app.

Shipping costs

  • Standard items (InPost) — £3.49, paid by the buyer at checkout.
  • Heavy items (Royal Mail) — Free for the buyer. The seller covers the shipping cost.

InPost locker delivery

This is the default for standard items. The parcel is sent to a self-service locker near the buyer and can be collected 24 hours a day.

For buyers

  1. During checkout, choose an InPost locker near you on the map.
  2. The seller ships the parcel to that locker.
  3. You get a notification when it arrives.
  4. Collect it from the locker with the code in the app.

For sellers

  1. After a sale, you receive a shipping label.
  2. Drop the parcel at any InPost locker.
  3. It is routed to the buyer’s chosen locker, and a tracking number is created automatically.

Royal Mail

Royal Mail is used for heavy items over 15 kg, which do not fit InPost locker limits. The item is delivered to the buyer’s address.

  1. The buyer’s delivery address is provided after the sale.
  2. Ship the item by Royal Mail.
  3. Enter the Royal Mail tracking number in the app.

Tracking

Open My Orders and the order details. Once the seller has shipped, the tracking number and link are shown there.

Delivery times

  • The seller has up to 7 days to ship after purchase.
  • InPost — Usually at the locker within 1–3 business days after the seller drops the parcel off.
  • Royal Mail — Typically 1–3 business days for UK addresses.

Heavy items

Anything over 15 kg is a heavy item. It cannot go in an InPost locker, so it ships by Royal Mail. The seller marks this when they create the listing. Shipping is free for the buyer.

If your parcel has not arrived

  1. Check tracking in the order. It may still be in transit.
  2. For InPost, confirm you are at the locker you chose.
  3. If tracking says delivered and you do not have the parcel, raise a dispute from the order within the 48-hour protection window.

Changing the delivery address

Once the order is placed, the address cannot be changed. An InPost locker cannot be changed after purchase either.

If the seller does not ship

If the seller does not ship within 7 days, the order is cancelled automatically and you receive a full refund, including the shipping fee. The seller is penalised for the missed shipment.

Home delivery

Standard home delivery is not available. Standard items are collected from an InPost locker. Heavy items are delivered by Royal Mail. For a shipping question, contact us or message the seller in the app.
