Shipping policy
Clear delivery, from payment to arrival.
Standard UK delivery is charged at £6.99 per order and is shown separately before checkout is submitted. Orders are prepared only after payment has cleared. This page explains our usual dispatch window, standard UK delivery estimate and what to do if a parcel is delayed, damaged or missing.

Unless a different timeframe is agreed, delivery will be completed without undue delay and within 30 days. If we cannot meet an agreed essential delivery date, contact us to discuss cancellation and a refund.
