Delivery When will my order arrive?
Allow 5–12 business days from checkout: 1–2 business days for us to pick and dispatch, then 4–10 business days with the carrier depending on where in the UK you are. These are typical times rather than promises — a tracking link lands in your inbox the moment your parcel ships.
Read the shipping policyReturns Can I send something back?
Yes — you have 30 days from delivery, whatever the reason. Get in touch first and we'll email the return address within 24 hours on business days; post the item back within 14 days after that. Keep items unused and in their original packaging. You cover return postage, unless we sent something damaged, faulty or incorrect — then it's on us.
Read the return policyRefunds How quickly does my money come back?
We inspect returns as they arrive, confirm by email, and refund your original payment method within 5 business days of receiving the parcel. Your bank or card provider may then take a further 5–10 business days to show it in your account.
Read the refund policyTracking How do I follow my parcel?
Every parcel ships tracked. Use the link in your dispatch email, or pop your details into our tracking page whenever you like. The first scan can take 24–48 hours to appear after dispatch, so an empty page right away is nothing to worry about.
Track an orderPayment How can I pay?
You can pay with American Express , Apple Pay , Google Pay , Maestro , Mastercard , PayPal , Shop Pay and Visa . Exactly which options appear at checkout depends on your device and region — Apple Pay shows on Apple hardware, for example. Every transaction runs over an encrypted connection and we never store your card details.
